Aim of the study was to evaluate the influence of clinical characteristics to the prognosis of disease and effectiveness of postoperative radiotherapy and adjuvant chemotherapy using lomustine, cisplatinum and vincristin in the treatment of children with medulloblastoma.
This study was performed 2000 – 2005 in the Kaunas University of Medicine Hospital, department of children diseases. The data of patients, treated with medulloblastoma in 1994 - 2003, were used in this study. During ten-years period in Lithuania the medulloblastoma was diagnosed for 32 children. Twenty-seven of them were included in this study.
The diagnostic tests made for the patients of the study: preoperative computer tomography or/and magnetic resonance imaging of brain; postoperative control computer tomography of brain; magnetic resonance imaging of spinal cord; bone scintigraphy with radioactive technetium; chest X-ray and ultrasound examination of the abdominal organs
The spread of the disease and size of the residual postoperative tumor separates patients of this study into two: standard and high risk groups.
Patients depending to the standard risk group were treated with radiotherapy alone. Patients included in the high risk group were treated by 2 different treatment methods: patients diagnosed with medulloblastoma between 1994 and 1998 were treated with craniospinal radiotherapy alone, other patients treated between 1999 and 2003 received radiotherapy with adjuvant chemotherapy with lomustine...

Skrandžio vėžys yra ketvirta pagal dažnį ir antra pagal mirtingumą onkologinė liga pasaulyje. Sergančių šia liga 5 metų išgyvenamumas siekia tik 25 proc. Esant didelei ligos atkryčio rizikai dažniausiai skiriama adjuvantinė chemoterapija, nors daugumoje atsitiktinių imčių studijų statistiškai reikšmingo išgyvenamumo pagerėjimo nenustatyta. Dažniausia skrandžio vėžio gydymo nesėkmės priežastis yra lokoregioninis recidyvas (40-65 proc. ligonių, kuriems atliktos radikalios operacijos) ir pilvaplėvės metastazės. Siekiant sumažinti lokoregioninių recidyvų dažnį, pradėtas taikyti suderintas chemospindulinis gydymas.
Šio tyrimo tikslas- nustatyti adjuvantinio gydymo efektyvumą po radikalių skrandžio vėžio operacijų su D2 limfadenektomija ir pagrįsti šio gydymo metodo tikslingumą. Darbo tikslui įgyvendinti buvo suformuluoti šie uždaviniai.
1. Įvertinti radikaliai dėl skrandžio vėžio operuotų su D2 limfadenektomija pacientų išgyvenamumą taikant adjuvantinį chemospindulinį gydymą arba adjuvantinę chemoterapiją.
2. Įvertinti adjuvantinio chemospindulinio gydymo toksiškumą po radikalių operacijų su D2 limfadenektomija, palyginti jį adjuvantinės chemoterapijos 5-fluoruracilu ir leukovorinu sukeliamu toksiškumu.
3. Įvertinti ankstyvos pooperacinės intraperitoninės chemoterapijos toksiškumą ir palyginti jos efektyvumą taikant su adjuvantiniu chemospinduliniu gydymu.

[toliau žr. visą tekstą]Gastric cancer is the fifth most common cancer and the second leading cause of cancer-related death worldwide. The 5-year survival rate of these patients is approx. 25. Adjuvant chemotherapy is frequently used for treatment, despite the fact that many randomized studies failed to demonstrate a better patient survival. The high rate of recurrence, even in patients undergoing state-of-the art curative resection, suggests that effective adjuvant chemoradiation and chemotherapy might indeed be an attractive concept to improve the overall outcomes of patients with gastric cancer. The aim of this study was to evaluate the effectiveness of the adjuvant therapy after curative resection with D2 lymphadenectomy for gastric cancer and determine its role in the treatment of cancer patients. The goals of this study were: 1. To compare the survival of patients receiving adjuvant chemoradiation or adjuvant chemotherapy after the curative resection with D2 lymphadenectomy for gastric cancer. 2. To evaluate the toxicity of the adjuvant chemoradiation after the curative resection with D2 lymphadenectomy for gastric cancer and to compare it with the toxicity caused by adjuvant chemotherapy with 5- Fluorouracil and Leucovorin. 3. To assess the toxicity of the early postoperative intraperitoneal chemotherapy and compare its effectiveness with the combined intraperitoneal chemotherapy and adjuvant chemoradiation therapy. 4.

1. INTRODUCTION
Colon and rectum cancers (CRC) accounted for about 1 million new cases in 2002 (9.4 % of the world total) with about 529,000 deaths and 2.8 million alive with CRC diagnosed within 5 years of diagnosis [Parkin DM et al, 2005]. Recent estimates indicate that in 2004 CRC among the most common incident form of cancer in the Europe was in the second position with more than 380,000 new cases (13.2% of total). CRC was also one of two most common causes of cancer deaths in Europe (203,700 per year) [Boyle P et al, 2005].
A favourable pattern in CRC mortality for both genders was observed in most of western European countries from the 1990s onwards, but CRC mortality rates were still in the upward direction in some eastern European countries [Fernandez E et al, 2005]. For patients diagnosed with CRC during the early 1990s, the EUROCARE study showed that differences in stage at diagnosis were a key explanation for differences in survival between western European countries, and differences in therapy contributed to survival differences between eastern and western European countries [Gatta G et al, 2000].
The number of new cases of CRC in Lithuania is increasing every year. According to the data of Lithuanian Cancer Registry, there were diagnosed 1442 new colorectal cancer cases and 973 deaths in 2004 in Lithuania [The main results of cancer control in Lithuania. Transitional report 2004. Lithuanian Cancer Registry]. CRC is in the third position according new cancer... [to full text]

Aim of the study. To estimate patients’ opinion of services at the chemotherapy day-care department
Methods. A survey was carried out at the Kaunas Medical University Hospital Chemotherapy department November 2004. 207 patients participated in it (response rate – 77,5 %). Statistical analysis was carried out using SPSS 11.5 for Windows. Associations between the variables were tested by Chi squared (χ²) test. Patients’ satisfaction with the doctors and nurses work was analyzed by measuring means that were compared using the Student test (t). Significance level (p) less than 0.05 was considered as statistically significant.
Results. The biggest part (93 %) of the patients at the Chemotherapy day-care department were satisfied with the services they received there. Only 7 % of the patients were satisfactorily happy about the services. Nobody was unhappy or very unhappy about them. Majority of the patients (98 %) think the day-care department is necessary, and even 89 % of the patients would recommend the department to other people. If they had to choose where to get the treatment, more than two thirds of the patients would chose this department. Majority of the respondents liked and liked very much the physical environment in the department. Functional quality of the services was evaluated positively, though nurses’ work they liked better than doctors work. Factors that influenced satisfaction were: sex (men were more satisfied than women), problems patients have while coming... [to full text]

Vėžys dažniausiai asocijuojamas su mirtimi. Vis dėlto, ankstyva diagnozė ir taikomi nauji efektyvūs ligos gydymo būdai leidžia vėžiu sergančiam ligoniui vis ilgiau išgyventi. Tačiau suvokiama, kad, siekiant kaip galima ilgiau išsaugoti vėžiu sergančio žmogaus gyvybę, svarbu ne tik išgyventų metų skaičius, bet ir šių metų kokybė.
Šiame darbe buvo siekiama įvertinti vėžiu sergančių moterų gyvenimo kokybės ypatumus priklausomai nuo vėžio formos (krūties, ginekologinis, kitos formos), gydymo metodo (chemoterapija ir spinduliavimas, kiti metodai), moterų šeimyninės situacijos (netekėjusios, ištekėjusios, kitas statusas) palyginimui pateikiant vėžiu nesergančių moterų rezultatus.
Keliama hipotezė, kad vėžiu sergančios moterys savo gyvenimo kokybę vertina prasčiau nei vėžiu nesergančios moterys. Taip pat keliama hipotezė, jog gyvenimo kokybė yra prastesnė tarp tų vėžiu sergančių moterų, kurios yra gydomos chemoterapija ir spinduliavimu, ar tų moterų, kurios yra neištekėjusios.
Gyvenimo kokybei vertinti buvo naudojamas Pasaulinės sveikatos organizacijos Gyvenimo kokybės – WHOQOL-100. Lietuviškai šis klausimynas vadinamas PSO-100. Šis klausimynas pasirinktas dėl to, kad tai yra vienas išsamiausių gyvenimo kokybės klausimynų. Beje, jis parengtas tyrimams Lietuvoje ir yra sėkmingai naudojamas.

But longer survival is not the main point recently. Recently more and more it is perceived that life quality is the essence, not only quantity of survived years. Here we aim to evaluate life quality of women who have cancer in regard to different cancer types (breast, gynaecological, other), different treatment methods (chemotherapy, other) and women marriage status (married, unmarried, other). Also for comparison purposes there is given life quality results of women who do not have cancer. It is thought that women with cancer have lower life quality comparing with women without cancer. Also it is thought that life quality is worse among women who are treated with chemotherapy, or among women who are unmarried. In order to evaluate life quality for the purposes of this research there was used life quality questionnaire of World Health Organization - WHOQOL-100. It was chosen because it is the one of more comprehensive tools for life quality evaluation. Also it is prepared for researches in Lithuania. Life quality questionnaire of World Health Organization - WHOQOL-100 allows to evaluate general life quality, 6 main factors and 24 subfactors. 6 main life quality factors are the following: physical health, psychological, level of independence, social relationships, environment, spirituality/religion/personal beliefs.

Full textAbstract:
Treatment of pancreatic cancer is an important medical problem. Most pancreatic cancer patients are diagnosed with advanced disease and their prognosis is poor. In Lithuania there were 440 new cases in year 2004. More than fifty percent of patients are diagnosed with stage IV disease [Kurtinaitis J et al., 2005].
Median survival of patients diagnosed with pancreatic cancer, depending on a stage of a disease, spread of the tumor, treatment method, functional status of a patient is from 6 to 20 months. Five-year survival is only 0–5 percent [Bramhall S et al., 1998; Oya N, 2004].
Today, pancreatic cancer is treated by combined methods: surgery combined with RT and/or chemotherapy. It is questionable if a patient diagnosed with pancreatic cancer in early stages must be treated by adjuvant treatment methods, or should patients diagnosed with unresectable cancer be treated with chemotherapy or ChRT; and what is more important for the patient: increased survival or better quality of life.
Kaunas University of Medicine Clinic (KMUC) is a suitable hospital to treat patients diagnosed with pancreatic cancer. At the Clinic of Surgery pancreatic cancer patients are treated by radical and palliative surgery; and at the Clinic of Oncology patients with pancreatic cancer are treated applying contemporary methods of RT, chemotherapy and combined treatment methods. In this thesis treatment results of patients treated for resectable and unresectable pancreatic cancer from year 1987 to year... [to full text]

1. INTRODUCTION
Lung cancer is the most common malignancy in the world and accounts for 1.09 million new cases with 972 000 deaths per year. In Lithuania too, lung cancer is the most commonly diagnosed cancer in men with nearly 1500 new cases each year. Lung cancer is five times more common in men than in women. At present, most patients who receive an initial diagnosis of lung cancer have advanced stage disease (stage IV – 30.2%), making cure with currently available therapies unlikely.
The main prognostic information with regard to survival is associated with the biological characteristics of the primary tumour (histological subtype, aggressiveness, differentiation, etc.), the extent of spread to regional or distant lymph nodes or to the other structures, and the operability of the patient (age, function of residual lung, co-morbidity).
Because the outcome is associated with the histological subtype and stage of the lung cancer at the diagnosis, there has been persistent interest in designing and testing various radiological methods for early detection of lung cancer. Chest radiography, computed tomography (CT), magnetic resonance imaging (MRI) can not only identify specific features in lung nodules, but add important information about the localisation, size and extent of the primary tumour (T), detect invasion of major mediastinal structures and chest wall, and locoregional (N) and distal spread of the tumour. Although theoretically features such as nodal shape... [to full text]

Full textAbstract:
Cancer treatment with polymer-bound cytostatic drugs and its potentiation through immunomodulation Poly[N-2-(hydroxypropyl)-methacrylamide] (PHPMA) is a synthetic water soluble and biocompatible polymer which can be used as a carrier of a cytostatic drug and an antibody as a targeting moiety. The antibody ensures the site-specific delivery of the conjugate. Nevertheless, even polymeric conjugates without any tumor-specific targeting moiety are passively accumulated within solid tumors via so called Enhanced Permeability and Retention (EPR) effect, in case that their molecular wight is at least 40 kDa. Antibody-targeted polymeric drugs have been shown previously to have a cytostatic activity in vitro and an antitumor activity in vivo. Since treatment of cancer diseases in practice is far from such ideal conditions and many tumors have no strictly specific marker suitable for targeted therapy, upgrading of the treatment efficacy represents the major challenge. One of the possible ways how to improve insufficient chemotherapy outcome can be using of a combination of polymer-bound cytostatic drug and potent immunomodulation able to induce a robust anti-cancer immune response. In this study, we have used B cell leukemia BCL1 as an experimental tumor model. BCL1 cells express surface IgM with an unique...

The diploma thesis deals with the protection of personnel in cytoreductive surgery and hyperthermic intraperitoneal chemotherapy, focusing on non-medical healthcare workers - anesthetist nurses. The aim of the work was to analyze the knowledge of anesthesia nurses in the use of personal protective equipment, the specifics of selection for the given performance, the use of an electrocautery with integrated suction, the availability of decontamination aids In case of an accident of cytotoxic substances and if the staff is afraid of their own health. The data was obtained through a questionnaire. For the research were selected anesthesia nurses working in operating theaters in selected health care facilities in the Czech Republic. The total number of respondents who participated in the research was 35. The results of the survey revealed that the staff did not find out what PPEs are recommended for this type of operation. It's either because the staff is less linguistically equipped or does not know EBN / EBP or EBM. The staff only uses those PPEs that are available to them. As a good result, 49% of respondents use an integrated electric exhaust system. With regard to the availability of decontamination aids, I have found that most of the staff does not know whether these utilities are available at...

Full textAbstract:
Tumor microenvironment is an area, where the local immunosuppressive effects dominate and prevents the immune system to perform its physiological functions. The cells infiltrating the microenvironment have an important function among many cell types since they produce a large quantity of factors suppressing the immune response. In our work, we monitored the immune changes in the microenvironment during tumor growth and chemotherapy. For these purposes, we utilized the methods for analysis of the proportion and phenotype of the distinct populations of immunocytes and for analysis of the total level of expressions of selected genes associated with immunosuppression or with distinct populations of immunocytes. The aim of our work was to discover, using two types of mouse tumors (TRAMP-C2 and TC-1/A9), how 5-azacytidine (5AC), a cytostatic drug with epigenetic activity, affects the proportion of leukocytes infiltrating the tumor microenvironment and, further, whether these changes are accompanied by decreased expression of immunosuppressing genes. In addition, we have also focused on the changes of relative expression of genes encoding markers of lymphoid lines and, on other immunoregulating genes, encoding IL-6, IL-10, IL-12, IL-4 and IFNγ cytokines, in the microenvironment of these tumors....

Breast cancer is the most frequent malignancy in women population both in the Czech Republic and worldwide. Treatment of this disease involves surgical removal of the tumor, radiotherapy, chemotherapy and hormonal therapy. Recently, targeted biological treatment is also approached. Each patient reacts to the treatment individually and thus high variability in response is common. Multidrug resistance (MDR) presents one of the most important obstacles to successful chemotherapy. MDR is often associated with a decreased intracellular accumulation of anticancer drugs and an increased expression of ABC transporters such asABCC1 of our interest. The ABC family of membrane transport proteins includes the well-known mediators of resistance to anticancer drugs. In particular, ABCB1, ABCC1 and ABCG2 actively perform efflux of various types of drugs from cancer cells, thereby conferring resistance to those agents. The main aim of this study was to asses the genetic variability of the ABCC1 gene in 191 patients with breast cancer and to determinate the expression profile of ABCC1 in 30 patients from this cohort who were treated preoperatively. We evaluated relations between ABCC1 genotype, or phenotype and prognostic factors including the result of chemotherapy. Gene expression was measured in preamplificated...

Hematooncological diseases are often accompanied by dietary restriction, especially in cytotoxic therapy. The main purpose of the work was to assess the effect of high-dose chemotherapy on the change of nutritional status in two groups of hematooncological patients. A total of 16 patients were enrolled. Changes of the body composition were evaluated using bioelectrical impedance analysis supplemented by monitoring of biochemical nutritional indicators. Observations showed that in both groups the majority lost weight. In the first group of eight patients with acute myeloid leukemia observed during three consecutive hospitalizations, the median of change of body weight was -3.7 kg (-4.3%). Loss of lean body mass with a median value of -4.8 kg (-7.2%) was detected at all patients. Body fat was reduced at half of the patients. In some cases, with length of observation, there was an increase in fat mass along with visceral fat. In the second group, which included eight patients (after autologous hematopoietic stem cell transplantation) at whom one hospitalization was evaluated, body weight was reduced at six patients. The medianof change of body weight was -2.1 kg (-2.3%). At five patients, the treatment representeda loss of active metabolic mass. The change of the weight of the lean body mass was shown...

We have monitored the DNA damage induced by tumor chemotherapy. The combination of platin derivate (cis-platine or carboplatin) and another chemotherapy agent (gemcitabin, paclitaxel or vinorelbin) was applied to patients with lung carcinoma. The whole chemotherapy includes 4 cycles. We have monitored the DNA damage in peripheral blood lymphocytes through the first and the third cycle of chemotherapy and 3 weeks after the last cycle of chemotherapy. For detection we have used comet assay which seems to be accurate and reliable method. Lymphocytes were isolated from whole blood through the medium LSM lymfocyte and then were processed by the alkaline version of the single cell gel electrophoresis. We have analysed single strand breaks (SSB) and interstrand cross links (ICL). For the measurement of ICL isolated lymphocytes were incubated in the presence of 200 µM of styrene oxide (SO) to degrade the DNA by inducing strand breaks. Incubation of peripheral blood lymphocytes with 200 µM SO leads to the formation of comets. If ICLs are present in the DNA, the alkaline unwinding of DNA is blocked and the % of DNA in tail is reduced. Comets were stained with ethidium bromide and then analyzed by the software LUCIA Comet Assay. The damage of DNA caused by SSB before the chemotherapy was relatively low and...

Full textAbstract:
Multidrug resistance (MDR) is a common cause of failure in chemotherapy for malignant diseases. Cancer cells develop MDR most often via the up-regulation of P- glycoprotein (P-gp) expression. P-gp is an efflux pump with broad specificity belonging to ATP-binding cassette (ABC) transporters which decreases the intracellular concentration of various drugs. We designed polymeric conjugates based on an N-(2-hydroxypropyl)methacrylamide (HPMA) bearing a cytostatic drug and/or P-gp inhibitor and tested their cytostatic/cytotoxic activity in vitro and their therapeutic efficacy in vivo in MDR tumors. We demonstrated that HPMA copolymer conjugates bearing both the cytostatic drug (doxorubicin (Dox) or pirarubicin) and the P-gp inhibitor (derivative of reversin 121 (R121) or ritonavir) possess remarkable cytostatic and cytotoxic activity in MDR tumor cell lines in vitro and superior antitumor activity in vivo. Notably, the HPMA copolymer conjugate bearing both Dox and R121 showed significant antitumor activity in both P388/MDR and CT26 mouse tumor models and was capable to completely cure 6 out of 8 mice with established CT26 tumors. We explored the potential of micelle-forming HPMA copolymer-poly(propylene oxide) (PPO) diblock bearing Dox to overcome MDR in vitro and in vivo. The HPMA copolymer-PPO diblock...

Introduction: Colorectal cancer (CRC) is one of the most frequent malignancies and affects approximately 5% of worldwide population. More than 75% of CRC cases represent sporadic forms. Susceptibility to nonhereditary CRC is significantly influenced by polymorphisms and mutations in low-penetrance genes. Variations in biotransformation and DNA repair genes may result in acumulation of toxins and DNA damage in cells leading to the development of cancer. Furthermore, different gene expression profiles of membrane transporters affecting the accumulation of anticancer drugs in tumour cells, e.g. ABC drug transporters, may largely influence inter-individual variability in drug response and chemotherapy outcome. The aim of this study was to evaluate the role of genetic and lifestyle factors in the risk of onset and progression of colorectal cancer. This study followed selected genetic alterations in xenobiotic-metabolizing enzymes (CYP1B1, GSTM1, GSTT1, GSTP1, NQO1 and EPHX1) and genes involved in response to DNA damage (CHEK2 and NBN), as potential CRC susceptibility factors. Another aim of this study was to investigate expression profile of all human ABC transporter genes to follow their prognostic and predictive potential in colorectal carcinoma. Materials and methods: The polymorphisms and other...

Breast carcinoma is the most common cancer among women in our country and worldwide. One of the obstacles to successful therapy is a multidrug resistance. It can be caused by different factors, such as overexpression of ABC transporters, or decreased expression of SLC transporters, deregulation of drug metabolizing enzymes, variability of the targets of anticancer drugs, failure of apoptosis or increased capacity of repair genes. The aim of this study was to search for associations of genes of drug transport and metabolism with the prognosis of patients or response to chemotherapy. From the view of preventive medicine, this aim constitutes an important part of both secondary and tertiary prevention of cancer, i.e., discovery of markers enabling optimal therapy selection for each patient, decreasing the risk of disease progression to advanced and resistant stage, and elimination of side effects of chemotherapy. The expression profile of ATP-binding cassette (ABC) transporters (49 genes), cytochromes P450 (CYPs, 10 genes), aldo-keto reductases (AKRs, 13 genes) and carbonyl reductase 1 was analyzed in the tumor and adjacent non- tumor control tissues in a cohort of neoadjuvantly treated patients. Genes deregulated in tumors compared with control tissues or genes associated with clinical data were assessed in...

Author: Bc. Martina Plšková Title: The effect of chemotherapy on the microflora in the oral cavity and intestinal microflora in cancer patients Field of study: Specialist in laboratory methods Objective: The aim of this study is to assess and compare changes of side effects of chemotherapy on the microflora in the oral cavity and large intestine in patients with colorectal cancer and breast cancer and to evaluate bacterial colonization during cancer treatment. Methods: Microbiological diagnostic testing of culture of swabs from the mouth and rectum. Results: The investigators found that chemotherapy has a important influence on the composition of microflora in the oral cavity and rectum. The biggest changes in the incidence of micro-organisms were observed in the Candida albicans, which is parcipitated for mucositis. Conclusions: Chemotherapy can damage the mucous membrane as in the oral cavity and in the intestine, resulting in an imbalance in the bacterial colonization of mucous membranes. This leads to an increased representation of conditionally pathogenic bacteria that are normally suppressed by the natural microflora.

The impact was assessed of clinical and nutritional factors on prognosis of 107 oesophageal cancer patients treated with neoadjuvant chemoradiotherapy (CHRT) and surgery. Individualised nutritional support, according to grade of dysphagia was carried out in all the patients. Serum leptin, soluble leptin receptors (SLR), TNF, IGF and fatty acid (FA) profiles in plasma phosphatidylcholine (PC) were studied as well. Addition of paclitaxel to carboplatin and continual fluorouracil significantly increased toxicity without influencing efficacy of the treatment. Post-operative node negativity, grade of dysphagia, weight loss and serum albumin were proved to be prognostic factors of survival and time to progression. CHRT led to decrease of SLR, palmitoleic and oleic acid and increase of n-3 polyunsaturated FA in PC. Lower concentrations of SLR were associated with improved survival of the patients.

Aim: 5-Fluorouracil (5-FU) is the most commonly used anticancer drug for colorectal cancer (CRC). Initially, we aimed to compare expression of 5-FU metabolic enzymes genes: thymidylate synthase (TS), thymidin phosphorylase (TP) and dihydropyrimidine dehydrogenase (DPD) in colorectal cancer and normal colon mucosa. We have tried to prove the correlation of the mRNA levels in fresh frozen tissues and protein expression using immunohistochemistry in paraffin-embedded colorectal cancer and adjacent normal tissues. Finally, we aimed to clarify the prognostic and predictive value of the expression of the 5-FU metabolic enzyme genes in patients with early colorectal cancer. (...) Results: We have found significantly higher DPD mRNA levels in normal colon tissue than in tumor tissue (p=0,03), but no significant differences in TS mRNA (p=0,34) and TP mRNA (p=1,0) levels in tumor and normal tissue. Immunohistochemically we have determined significantly higher TS expresion in tumor than in normal tissue (p=0,02) and significantly higher TP expression in stroma 9 cancer tissue than in normal tissue (p<0,001).

Changes in the regulation of apoptosis and cell cycle are involved in tumor development, progression, and resistance to antitumor therapy. The aim of this work was to evaluate the importance of apoptotic caspases and regulators of cytokineses as possible prognostic and predictive markers in breast carcinoma patients. In addition to determining the transcript levels of selected genes in tumor and control tissues obtained from breast carcinoma patients, we have also focused on the importance of alternative splice variants of caspases and their potential genetially determined regulation. We analysed the obtained data in relation to the clinical-pathological characteristics of the tumors, the progression-free survival of patients and to the response of the patients to the neoadjuvant chemotherapeutic treatment. Part of the work was determination of protein expression levels and verification of the importance of selected candidates for the effect of chemotherapy by functional study.

The dissertation is focused on the effect of three antivirals (acyclovir, rimanatadine or zidovudine) for their potencial use in the process of chemotherapy in the combination of meristem culture method as a possible method for Onion yellow stripe virus, Leek yellow stripe virus, Garlic common laten virus and Shallot latent virus eradication in in vitro conditions. Antivirals were always applied separately into cultivation media and two amounts of antivirals (25 or 50 mg.l-1) were used. The treatment time was two weeks. Meristem culture only was a control method. Murashige and Skood medium was used for all variants. During the first year, young plants of the variety D Alsace Freres cultivated in vitro were treated with chemotherapy. These plants had been treated with the meristem culture only in the past but the treatment had not been successful. The virus presence was detected with the ELISA method. Rimantadine variant in the amount of 50 mg.l-1 was the most effective variant for the monitored virus elimination. More sensitive method reverse transcription polymerase chain reaction (RT-PCR) was optimized for monitored viruses in the next parts of this work. Garlic common latent virus (GCLV) primers were designed as well. During the second year, the chemotherapy was applied on explants with the size 0.8 mm during meristem culture. Explants of the varieties Blanin, Sukoradský and Japo, however, did not regenerate and the chemotherapy could not be evaluated. In the next two years of the work, the chemotherapy was applied on individual cloves of the Unikát variety. Whilst detecting the presence of viruses in plants prior the treatment, it was established that only one plant was free from all the monitored viruses. After treatment, acyclovir variant in amount of 25 mg.l-1 was evaluated as the most effective variant for the virus complex elimination, and also from the economical point of view. Real-Time PCR method for virus detection has been started in the dissertation. The detection of GCLV was optimized from the start. Isolates which had been negative for the GCLV presence after RT-PCR were tested with Real-Time PCR. A higher percentage of GCLV positive plants were detected with Real-Time PCR. Real-Time PCR optimization for other viruses will be the objective of futur experiments.

The submitted thesis is based on comparison of therapeutical effectivity of two different methods using in multiple myeloma patients for therapy. The best therapy seems to be single or tandem autologous stem cell transplantation ASCT with stimulation and separation of periferal blood stem cells (PBSCs). The stimulation could be done by CFA (cyclofosfamid) or cytostatik combinaňtion, e.g. IVE (ifosfamide, vepeside, epirubicine) in combination with G - CSF (granulocyte - colony - stimulating factor). The question which is not answered is which one of those methods is more effective. And which one of single or tandem ASCT is more profitable if any. The goal of the study is to compare two different methods of stimulation and separation of PBSCs (CFA and IVE). I compare the effectivity from a viewpoint of breeding PBSCs and also time consuming of the separation meňthods. Nobody has done this comparison before us. To separate PBSCs was used COBE Spectra apheresis systém. Spectra is efficient to separate the whole blood into its components. The group for my study were 167 patients with Multiple Myeloma.

A new method was developed for testing antiviral compounds against plant viruses based on rapidly growing brassicas in vitro on liquid medium. While using ribavirin as a standard for comparison, phytotoxicity and ability of the acyclic nucleotide analogues(R)-PMPA, PMEA, PMEDAP, and (S)-HPMPC to eliminate ssRNA Turnip yellow mosaic virus (TYMV) were evaluated by this method. Double antibody sandwich ELISA was used for relative quantification of viral protein in plants. Ribavirin had the most powerful antiviral effect against TYMV. On the other hand, (R)-PMPA and PMEA had no antiviral effect and almost no phytotoxicity compared to the control. (S)-HPMPC and PMEDAP showed moderate antiviral effect, accompanied by higher phytotoxicity.

Chemotherapy is one of the basic therapeutic procedures of breast cancer (BC) which may precede and/or follow the surgical resection of a tumor as a part of neoadjuvant or adjuvant therapy. However, the selective pressure of chemotherapy on tumor cells may change their molecular and expression profile and thus also their chemosensitivity. The aim of our work was to document the expression changes of selected markers in BC after neoadjuvant chemotherapy, which may contribute to the understanding of the role of these proteins and genes in tumor response to chemotherapy and the development of chemoresistance. Immunohistochemical analysis of expression of standard BC markers [estrogen (ER) and progesterone receptors (PR), HER2 and proliferation activity (Ki67)] and intercellular junction proteins (claudin 1, 3 and 4, E- and N-cadherin) before and after neoadjuvant chemotherapy revealed a decrease of PR, Ki67 and claudin 3 expression and an increase of claudin 1 expression. The expression of ER, HER2, claudin 4, E- and N-cadherin proved to be stable. Assessment of standard BC markers is performed routinely during a bioptic investigation as a necessary factor for therapy indication.

Full textAbstract:
The transplantation of bone marrow - more generally said of hematopoietic cells - is in the present time one of the modern therapeutical methods used in cases of malfunction of haematogenesis inside of the bone. The ususal reason for going through with transplantation is leukemia, lymphomas, also anemia, congenital metabolic disorders, autoimmune disorders or some of the solid tumors. Thanks to the transplantation of hematopoietic cells, it is possible to highten the chance of restoration in more than 50 % of patients suffering from oncological disease. The submitted thesis is processed in theoretical form, it is goal is to present the important points leading to progress of this presently very much used treatment and also thorough descripton of present trends in the area of transplantation of hematopoietic cells, that are almost identical in local transplatation centers as they are in the world. Another goal is to describe the role of a general nurse during providing of the care for a patient before and after transplantation of hematopoietic cells. The thesis is focused on the key areas of the issues of transplatation of hematopoietic cells and it is divided into several parts. The first part deals with the general description of the topic, it presents short introduction into the transplantation of hematopoietic cells, the basic division, historical and current indications and short preamble into todays trends. It describes closely the area of the registry of the bone marrow donors, which is the basics for the choosing of the suitable unrelated donor. The second part of the thesis deals with the desciption of historical progress since the very beginnings, through the progress during postwar period, the development of 70s and 80s of the previous century and also the 90s of the 20th century up until the present day. The third part is focused on current methods of collection of hematopoietic cells and following transplatation, it also describes closely the ways of donating hematopoietic cells, the preparation of the patient for transplantation, the course of transplantation and what should the patient prepare for during the early posttransplantation period. The fourth part is focused on nursing, it states thoroughly the role of a nurse in the nursing care before and after transplantation of hematopoietic cells, the principles a nurse has to abide by, and it also closely describes the role of a nurse during transplant application. It also describes dietary and important regimen measures the patient is set to follow after transplantation. The last part is focused especially on complications that are possible after hemopoetic cells transplantation. The necessary data have been obtained through thorough study of professional Czech and foreign monoghraphs and scientific periodicals. The acquisition of the data was significantly contributed to by the attended internsip in Internal hematological and oncological clinic of the Faculty hospital Brno Bohunice. The findings regarding nursing were obtained especially by the study of nursing standards. This thesis points out the important role of transplatation of hemopoetic cells as a method of treatment predominantly of hemooncological illnesses in current medicine and the most important roles of a nurse during the nursing of transplantation patients. The thesis provides a comperehensive overview on the issue of transplants of the hematopoietic cells and describes key areas that are considered as important. It focuses on the historical progress and the desciption of present trends thanks to which the transplantology can be considered as a highly professional and top field. It also highlights the main roles of a nurse during nursing that must be proffesional, qualified, meticulous, considerate and individualized. The results of the survey are supposed to provide the professional and amateur public enough information about the issue of transplantation of the hematopoietic cells.

Full textAbstract:
Acute myeloid leukemia (AML) is a very heterogeneous disease associated with cytogenetic aberrations and genetic mutations. Many of these changes have been revealed and their detection became usual part of the diagnostic process today. However, changes of expression profiles of small, noncoding RNAs, so called microRNAs (miRNAs), are less known and not used for diagnostics yet. These RNAs, 19-24 nucleotides long, take part in the regulation of expression of different genes through complementary base pairing to the 3'non- translated region (3'UTR) of the target messenger RNA (mRNA). They can influence key processes of the cell, like differentiation, proliferation or apoptosis. The changes in expression of different miRNAs are known from different types of cancers. In solid tumors, they are usually detected from bioptic samples; but also plasma samples are now in the center of attention as so called liquid biopsies providing the information about molecular genetic events in the organism. Many studies have revealed deregulated miRNAs in the bone marrow, full blood or isolated progenitor cells (CD34+) of AML patients, only four of them have analyzed plasma samples. We focused on the plasma samples and we targeted on such miRNAs, which levels differ at AML diagnosis and after the chemotherapy. Out of...

Introduction Axillary dissection has little diagnostic and therapeutic benefit in the node-positive breast cancer patients in whom axillary disease has been completely eradicated after neoadjuvant chemotherapy (ypN0). We sought to assess the efficacy of an algorithm used for the identification of the ypN0 patients consisting of intraoperative evaluation of sentinel and tattooed (initially positive) lymph nodes. Methods Included were T1 and T2 breast cancer patients with one to three positive axillary lymph nodes marked with carbon who were referred for neoadjuvant chemotherapy followed by a surgery. Axillary dissection was performed only in the patients with residual axillary disease after neoadjuvant chemotherapy on ultrasound or with metastases described in the sentinel or tattooed lymph nodes either intraoperatively or in the final histology. Results Out of 62 included initially node-positive patients, 15 (24%) were spared axillary dissection. The detection rate of tattooed lymph node after neoadjuvant chemotherapy was 81%. The ypN0 patients were identified with 91% sensitivity and 38% specificity using ultrasound and intraoperative assessment of both sentinel and tattooed lymph node according to the final histology. Discussion/Conclusion Lymph node marking with carbon dye is a useful and...

Key words: adenocarcinoma of the esophagus and esophagogastric junction, neoadjuvant chemotherapy, PET/CT, histopathological response, technique of esophagogastric anastomosis, anastomotic leak, anastomotic stricture Previous studies have shown that preoperative chemotherapy of locally advanced AEG is beneficial only for patients with a good histopathological response, the so-called responders. The aim of the first part of the thesis was to prospectively verify whether positron emission tomography (PET/CT) could be used for early identification of histopathological non- responders, who could be spared ineffective neoadjuvant treatment. Our study did not prove that the early metabolic response, expressed as the percentage change of the consumption of glucosis on PET/CT performed before (PET1) and 12 to 22 days after the start of the first cycle of preoperative chemotherapy (PET2) correlated with the histopathological response in the resection specimen in the entire population of 90 patients. In a post hoc explorative analysis we found the correlation between metabolic and histopathological response in a subgroup of patients with PET2 performed ≤16 days after the start of the therapy, but this hypothesis needs to be prospectively validated. Our study suggests that PET/CT performed after the first...

Charles University Faculty of Pharmacy in Hradec Králové Department of Biochemical Sciences Candidate: Nikola Jaščevská Supervisor: PharmDr. Anna Jirkovská, Ph.D. Title of diploma thesis: The effects of topoisomerase II beta on the sensitivity of the cancer cells to the antineoplastics Topoisomerase II (TOP II) is a cellular enzyme responsible for solving topological problems of double-stranded DNA. Alpha and beta isoforms of TOP II are different gene products having similar catalytic activities. The expression of TOP IIα is cell-cycle dependent, peaking in G2/M phase, while TOP II isoform is expressed constitutively throughout the cell cycle. It is therefore present also in non-proliferating differentiated cells. Anthracycline antibiotics are an old class of anticancer drugs, belonging to TOP II poisons. Although their clinical usefulness is high, the incidence of side effects (especially myelotoxicity and cardiotoxicity) may limit the therapy. The key role of TOP II inhibition, which is present also in cardiomyocytes, has been increasingly discussed. Dexrazoxane, the only clinically used cardioprotective, leads to depletion of TOP II in cardiomyocytes, which may explain its cardioprotection. Although TOP II was previously shown to be dispensable for cellular proliferation, its possible...

Cancer remains one of the most pressing issues of contemporary science and medicine. Incidence of malignant diseases is rising worldwide and they represent a major problem for the society due to both economic and ethical issues they cause. Although the progress in cancer biology, therapy and immunology has led to the introduction of many novel therapeutic protocols, approaches and drugs with specificity defined on a molecular level into clinical practice, many malignancies retain their poor prognosis. Therefore, intense research into new ways to increase our therapeutic options is warranted. Unfortunately, bringing a completely novel drug into clinical use takes extremely high amounts of time and money and entails a high risk of failure. Therefore, a promising approach has been recently adopted which lies in repurposing compounds already used in human medicine for cancer treatment. This form of research can advance through clinical trials for a new indication much easier, faster and cheaper than researching completely new drugs. The aim of this study was to examine the anticancer potential of one such drug, mebendazole. An anthelminthic from the family of benzimidazoles, mebendazole has been in common clinical use from the 1970s and is marked by its low toxicity as well as its very low solubility....

Tumor malignancies are the second leading cause of death worldwide. One of the reasons for the failure of oncological treatment are the uniformly set clinical guidelines, which neglect the effect of high intertumoral heterogeneity. The in vitro chemosensitivity and resistance (CSRA) assays allow for the stratification of patients prior to therapy. Therefore, the CSRA are a long-considered method for personalization of components of chemotherapy regime. Nevertheless, none of them is being routinely used in clinical practice. Certain chemotherapeutics used for their cytotoxic and cytostatic effect are also able to induce so-called immunogenic cell death (ICD) of tumor cells and activate an anti-tumor immune response. Monitoring of changes in the expression of molecules associated with the regulation of the innate immune system on the surface of dying tumor cells would enable to predict the patient's ability to respond to treatment involving modern immunotherapeutics. The feasibility of CSRA using flow cytometry and microscopy is critically evaluated in this thesis on a model of bladder cancer. Simultaneously, the correlation of the immunogenic phenotype of tumor cells and their sensitivity to selected chemotherapeutics is discussed.
