Purpose To determine the role of lung transplantation in the treatment of patients presenting with bronchogenic carcinoma and end-stage lung disease. Methods An international survey was conducted to determine the outcome of patients with bronchogenic carcinoma in the explanted lung at the time of transplantation. A group of 69 patients was collected from 33 centers. Results Twenty-six patients underwent 29 lung transplantations for advanced multifocal bronchioloalveolar carcinoma (BAC) as the primary indication for transplantation, and 13 developed a recurrence, with an overall 5-year actuarial survival of 39%. Incidental bronchogenic carcinomas classified as stage I (n = 22), II (n = 12), and III (n = 2), or as incidental multifocal BAC (n = 7), were found in the explanted lung of the remaining 43 patients. The 5-year actuarial survival was 51% in patients with stage I carcinomas, and was significantly better than for patients with stage II and III carcinomas (survival of 14%) or with incidental multifocal BAC (survival of 23%). Time from transplantation to recurrence and from recurrence to death was significantly longer in patients with multifocal BAC than in patients with other types of bronchogenic carcinoma. In addition, the site of recurrence was limited to the transplanted lung in 88% of the patients with multifocal BAC, whereas it was always widespread in patients with other types of bronchogenic carcinoma. Conclusion This study demonstrates that long-term survival can be achieved after lung transplantation in patients with stage I bronchogenic carcinoma or with advanced multifocal BAC.

Background: The Connection between smoking and lung cancer is now generally accepted. The objective of this studywas to observe smoking habits among different histological types of bronchogenic carcinoma. Setting: Bahawal Victoria Hospital,Bahawalpur. P e r i o d : April 2000 to March 2003. M e t h o d s : This was a simple descriptive study comprising of 30 consectivehistopathologically / cytologically confirmed cases of bronchogenic carcinoma that were admitted in different medical units of BahawalVictoria Hospital, Bahawalpur. History regarding smoking was taken in detail including type of smoking, quantity of tobacco smoked andduration of smoking in years. Smoking patterns were observed with their age, gender, living conditions and type of bronchogenic carcinoma.Results: Among eighteen cases of squmous cell carcinoma, history of smoking was present in all males. Only one female who belongedto a village was non- smoker. Cases with small cell carcinoma were six in total and all were males with five smokers, three urban areas andtwo rural areas. Only one was a non- smoker with a rural background. Three females and one male had adenocarcinoma. One male fromcity and one female from a village were smokers, while remaining two females were non-smoker and lived in urban areas. Two men sufferingfrom large carcinoma were smokers residing in urban areas. C o n c l u s i o n : Cigarette smoking is present in 87% of all bronchogenic carcinomaespecially with squamous cell, and large cell varieties. The involvement of smoking cases of adenocarcinoma has been found to be the leastcommon.

Summary:PET/CT imaging is most likely to be of use in radiation oncology with patients who have poorly defined target volume areas, e.g. brain tumours, bronchogenic carcinoma, and cases of miscellaneous geographical miss. Other tumours that call for dose escalated radiotherapy, such as head and neck tumours, bronchogenic carcinoma, and prostate carcinomas may further benefit from an accurate delineation of the metabolically active tumour volume and its differentiation from surrounding healthy tissue, or tumour atelectasis.

Bronchogenic carcinoma (lung cancer) is a major source of morbidity and mortality in industrialized nations. Although bronchogenic carcinoma is largely a preventable neoplasm, it will undoubtedly remain a major medical concern throughout this century, and considerable effort needs to be directed towards its early detection, establishing effective treatment, and understanding the neoplastic process. The objective of this study was to develop a practical and reliable model of localized bronchogenic carcinoma in laboratory rodents. This was done by impregnating cotton threads with the potent carcinogen, benzo(a)pyrene (BP). These BP-impregnated threads were then coated with a silicone rubber sheath to control the release of BP from the threads. The prepared threads were sewn around four cartilage rings in the ventral tracheal wall of guinea pigs and hamsters. The animals were sacrificed periodically, and two histopathologists graded the tracheal epithelium adjacent to the thread. The first experiment consisted of 94 Camm-Hartley guinea pigs: 48 experimental animals with BP-impregnated threads and 46 control animals with non-impregnated threads. The second experiment consisted of 70 Golden Syrian hamsters: 54 experimental and 16 control animals. The data showed that the implantation of the thread in the trachea induced a regenerative hyperplasia of the epithelium, and that the BP initiated carcinogenesis. Squamous metaplasia and progressive intraepithelial neoplasia (IEN) was evident prior to the development of squamous cell carcinoma (CA). In the experimental guinea pigs, only one guinea pig developed an invasive CA at 265 days. In the experimental hamsters, the first CA was seen at 55 days and after 120 days, 65% of the animals showed histopathologic evidence of CA. Most of the hamsters with CA also had spindle cell tumors in the tracheal stroma. The control hamsters and guinea pigs did not develop IEN, and the mature respiratory epithelium was reconstituted. We conclude that this method produced localized, readily accessible preneoplastic and neoplastic lesion in the trachea of hamsters, and to a lesser extent in guinea pigs. The model should prove useful in the study of tumor ultrastructure, the immunologic response to cancer, and the relationship of diet to cancer.<br>Medicine, Faculty of<br>Pathology and Laboratory Medicine, Department of<br>Graduate

UVOD: Savremenim dijagnostičkim i terapijskim dostignućima, kao i unapređenjem preventivnih mera produžen je životni vek ljudi. Starenje stanovni&scaron;tva je fenomen koji zahvata ceo svet. Povećanje broja starijeg stanovni&scaron;tva je udruženo sa porastom broja obolelih od karcinoma u ovoj starosnoj grupi, jer je starenje samo po sebi riziko faktor za nastanak karcinoma. Incidenca pojave karcinoma naglo raste od 50-te godine života sa vrhom u 80-toj godini života. U osoba starijih od 65 godina se dijagnostikuje 58% svih karcinoma, a 30% u starijih od 70 godina. Godine starosti nisu kontraindikaciija za sprovođenje hemioterapije kod starih bolesnika sa karcinomom. Starenje je povezano sa izmenjenom farmakodinamikom i farmakokinetikom antitumorskih lekova i povećanom osetljivo&scaron;ću normalnog tkiva na toksične komplikacije, te je odluka kliničara kod davanja hemioterapije ovoj starosnoj kategoriji bolesnika sa karcinomom uvek vrlo kompleksna i zahteva dobru procenu i odgovarajuću selekciju bolesnika za ovaj tretman. MATERIJAL I METODE: Doktorska disertacija obuhvata rezultate delom restrospektivnog, a delom prospektivnog opservacionog istraživanja sprovedenog u periodu 01.01.2011. do 31.12.2013.godine u Institutu za plućne bolesti Vojvodine u Sremskoj Kamenici, u kojem je praćeno 152 bolesnika starosti 65 i vi&scaron;e godina kod kojih je dijagnostikovan nemikrocelularni karcinom bronha u uznapredovalom stadijumu bolesti, a koji su lečeni kombinovanim hemioterapijskim režimom na bazi platine. Kao prognostički faktori su uzeti: starosna dob bolesnika (grupa mlađih od 75 godina i starih 75 i vi&scaron;e godina), pol, navika pu&scaron;enja cigareta (pu&scaron;ač, nepu&scaron;ač, biv&scaron;i pu&scaron;ač), navika konzumiranja alkohola, performans status (prema ECOG-Eastern Cooperative Oncology Group skali) u momentu postavljanja dijagnoze, patohistolo&scaron;ki tip tumora (adenokarcinom, skvamozni karcinom, drugo), stadijum bolesti (IIIb, IV), veličina tumora (manje od 6 cm i 6 cm i vi&scaron;e), TNM status prema klasifikaciji tumora (7.revizija), parametri krvne slike (vrednosti leukocita, hemoglobina, trombocita), biohemijski parametri (vrednosti laktat-dehidrogenaze (LDH), alkalne fosfataze, aspartat- aminotransferaze (AST), alanin-aminotransferaze (ALT), kalijuma, natrijuma, bilirubina) na početku terapije, komorbiditeti u momentu postavljanja dijagnoze (broj komorbiditeta po sistemima, Charlson index), simptomi bolesti (ka&scaron;alj, hemoptizije, otežano disanje, bol u grudnom ko&scaron;u, promuklost, smetnje gutanja, sindrom gornje &scaron;uplje vene, bol u kostima, simptomi od strane centralnog nervnog sistema, povi&scaron;ena telesna temperatura), gubitak na telesnoj masi (vi&scaron;e od 5% u prethodnih 6 meseci), indeks telesne mase (&lt;18,5kg/m&sup2; pothranjen, 18,5-24,9kg/m&sup2; normalno uhranjen, 25-29,9kg/m&sup2; prekomerna telesna masa, ˃30kg/m&sup2; gojaznost). Svi potencijalni prognostički faktori su evaluirani univarijantnom analizom, a potom su svi faktori rizika za koje je utvrđena značajnost analizirani primenom multivarijantne logističke regresije, u cilju prepoznavanja nezavisnih prediktora za dvogodi&scaron;nje preživljavanje. Za otkrivanje nezavisnih prediktora preživljavanja na dve godine je primenjena binarna logistička regresiona analiza, a kao potencijalni prediktori su bile sledeće varijable: starost ispod 75 godina, pu&scaron;ačka navika, patohistolo&scaron;ki tip karcinoma, stadijum bolesti IV, T4 status, M1b status, prisustvo respiratornog komorbiditeta, otežano disanje, bol u grudima. Kumulativno preživljavanje je prikazano Kaplan-Meier-ovim krivama. Primenom multivarijantne Cox- regresione analize su dobijeni nezavisni prediktori kumulativnog preživljavanja. Iz dobijenih prognostičkih faktora koji se izdvajaju kao nezavisni prediktori za preživljavanje su kreirani matematički modeli za dvogodi&scaron;nje preživljavanje. CILJ ISTRAŽIVANJA: Utvrditi uticaj pojedinih prognostičkih faktora na dvogodi&scaron;nje preživljavanje ovih bolesnika i iz toga izvesti matematički model za stratifikaciju ovih bolesnika u odnosu na dvogodi&scaron;nje preživljavanje. REZULTATI: Analizom prognostičkih faktora je utvrđeno da grupa bolesnika starih 75 godina i vi&scaron;e ima ne&scaron;to duže dvogodi&scaron;nje preživljavanje od grupe bolesnika mlađih od 75 godina, ali bez statističke značajnosti, bolesnici sa tumorom veličine 6 cm i vi&scaron;e imaju kraće dvogodi&scaron;nje preživljavanje u odnosu na bolesnike sa tumorom manjim od 6 cm, bolesnici kod kojih je u momentu postavljanja dijagnoze T status tumora bio T4, a M status M1b imaju kraće dvogodi&scaron;nje preživljavanje, bolesnici kod kojih je na početku tretmana u laboratorijskim nalazima bila prisutna anemija i povi&scaron;ene vrednosti LDH imaju kraće dvogodi&scaron;nje preživljavanje, prisustvo vi&scaron;e komorbiditeta utiče na kraće preživljavanje, bolesnici sa gubitkom na telesnoj masi većim od 5% u periodu 6 meseci pre postavljanja dijagnoze bolesti imaju kraće dvogodi&scaron;nje preživljavanje. Kreirana su dva matematička modela (jedan za preživljavanje na 2 godine i jedan za kumulativno preživljavanje) za stratifikaciju gerijatrijskih bolesnika sa uznapredovalim stadijumom nemikrocelularnog karcinoma bronha lečenih hemioterapijom na bazi platine u odnosu na dvogodi&scaron;nje preživljavanje. ZAKLJUČAK: Dobijeni matematički modeli za preživljavanje gerijatrijskih bolesnika sa uznapredovalim stadijumom nemikrocelularnog karcinoma bronha lečenih hemioterapijom na bazi platine na jednostavan način stratifikuju bolesnike u odnosu na preterapijske prognostičke faktore za razliku od sveobuhvatne gerijatrijske procene koja je vremenski zahtevna procedura i zahteva obučen kadar.<br>INTRODUCTION: Nowadays life expectancy is prolonged due to modern diagnostic and therapy achievements, as well as promotion of preventive measurements. Aging of population is a phenomenon in the whole world. Increasing number of elderly population is accompanied with the increased number of diagnosed cancer in this age group, because the aging themselves is a risk factor for development of cancer. The appearance of cancer rapidly rises from the age of fifty with the peak at the age of eighty. 58% of cancer diagnoses are in the people older than sixty-five years and 30% in people older than seventy years. The age is not contraindication for chemotherapy treatment in older patient with cancer. The aging is associated with disturbed pharmacodynamics and pharmacokinetics of antitumor drugs and increased susceptibility of normal tissue for toxic complications, therefore clinical decision for introducing chemotherapy is very complex and requires good assessment and proper selection of the patients for this treatment. MATERIAL AND METHODS: This doctoral thesis includes results of partly retrospective and partly prospective observational research conducted in the period 01.01.2011. until 31.12.2013. at the Institute for pulmonary diseases of Vojvodina in Sremska Kamenica, which includes 152 lung cancer patients 65 and more years old with diagnosed non-small cell lung cancer in advanced stage treated with combined platinum based chemotherapy regimen. These prognostic factors are included: age of patients (group &lt;75 years, group &ge;75 years old), sex, smoking cessation (smoker, former smoker, non smoker), alcohol consuming habit, performance status (according to the ECOG-Eastern Cooperative Oncology Group scale) in the moment of confirmed diagnosis, pathohistological type of tumor (adenocarcinoma, squamous cell carcinoma, other), stage of disease (IIIb, IV), tumor size (&lt;6cm and &ge;6cm), TNM status according tumor classification (7th revision), blood count parameters (leucocyte, hemoglobin level, thrombocyte), biochemical parameters (lactate-dehydrogenase level (LDH), alkaline phosphatase level, aspartate aminotransferase level (AST), alanine aminotransferase level (ALT), potassium level, sodium level, bilirubin level) on the start of the chemotherapy, comorbidities at the moment of diagnosis (number of comorbid conditions, Charlson index), symptoms of the disease (cough, hemoptysis, dyspnea, chest pain, hoarseness, swallowing difficulties, caval venae compression symptoms, bone pain, central nervous symptoms, increased body temperature), weight loss (˃ 5% in the previous 6 months), body mass index (&lt;18,5kg/m&sup2; underweight 18,5-24,9kg/m&sup2; normal weight, 25-29,9kg/m&sup2; overweight , ˃30kg/m&sup2; obese). All potential prognostic factors were evaluated with univariante analysis, and after that all factors with confirmed significance were analysed with multivariante logistic regression, in order to identify independent predictors for 2-year survival. Binary logistic regression analysis was applied for identifying independent predictors for 2-years survival and those variables were analysed : age &lt;75 years, smoking cessation, pathohistological type of cancer, stage of disease IV, T4 status, M1b status, presence of respiratory comorbidity, dyspnea, chest pain. Cumulative survival of those patients was shown with Kaplan-Meier prognostic curves. Two mathematical model for 2-year survival was created from the factors confirmed as independent predictors for survival. AIM: This research objectives were to determine the influence of certain prognostic factors on 2-years survival of those patients and to create mathematical model for stratification of those patients related to 2-years survival. RESULTS: Univariante analysis confirmed that the group of patients older than 75 years and more have had better 2-year survival than group of patient younger than 75 year, but without the statistically significance, patients with tumor size &ge;6cm have had worst 2-year survival in comparison with patients with tumor size &lt;6cm, patients with tumor status T4 at the moment of diagnosis and M status M1b have had the shorter 2-year survival, patients with anemia and increased LDH level on the start of the chemotherapy treatment have had shorter 2-year survival, the presence of more comorbid conditions at the moment of diagnosis influence on shorter 2-year survival, patients with weight loss more than 5% in the previous 6 months have had shorter 2-year survival. Two mathematical models were created (one for 2-year survival and the other for the cumulative survival) for stratification of elderly patients with advanced staged non-small cell lung cancer treated with combined platinum based chemotherapy regimen related to 2-year survival. CONSLUSION: Created mathematical models for stratification of elderly patients with advanced staged non-small cell lung cancer treated with combined platinum based chemotherapy regimen more easily stratify patients compared to pretreatment prognostic factors as opposed to comprehensive geriatric assessment which is time-consuming procedure and requires trained personnel.

Thesis (MMed)--Stellenbosch University, 2014.<br>ENGLISH ABSTRACT: Background: Sputum is a non-invasive, economic investigation whereby bronchogenic carcinoma can be identified. Manual cytological screening is labour intensive, time-consuming and requires a continuous high level of alertness. Automation has recently been successfully introduced in gynaecological cytology. Since sputum samples are similar to cervical smears, the question arises as to whether they are also suitable for automated screening. Objective: This study presented with various objectives: 1) To test automated sputum screening using the BD FocalPoint™ Slide Profiler (FP) and compare with manual sputum screening. 2) To determine the sensitivity and specificity of sputum in identification of bronchogenic carcinoma. 3) To ascertain if any clinical, radiological or bronchoscopy findings would be predictors for bronchogenic carcinoma. 4) To determine the significance of adequacy. Method: Sputum samples were collected prospectively from patients attending the Division of Pulmonology at Tygerberg hospital for a transbronchial fine needle aspiration biopsy (TBNA) or a transthoracic fine needle aspiration biopsy (TTNA) for the period from 2010 to 2012. A pre-bronchoscopy sputum was collected and submitted for processing. Stained slides were put through the FP for automated screening. After slides were qualified, sputum slides were put back in the routine screening pool. Correlation was done using the TBNA/TTNA result as the standard to evaluate the sputum results. Results: 108 sputum samples were included in this study. Of the 84.3% malignant (n=91) and 15.7% benign (n=17) cases confirmed with a diagnostic procedure, sputum cytology had a sensitivity of 38.5% (35/91 malignant cases), and a specificity of 100% (17/17 benign cases). Automated screening had a better sensitivity of 94.3% (33/35 positive sputum cases), while manual screening showed a sensitivity of 74.3% (26/35 positive sputum cases) when compared to the final sputum result. Individual parameters with a significant association with positive sputum included the presence of an endobronchial tumour, partial airway obstruction / stenosis, round mass, spiculated mass (negative association), loss of weight (negative association) and squamous cell carcinoma as the histological subtype. Adequacy was not as significant as hypothesised since 85.3% of true positive sputum, but also 65.5% of false negative sputum, had large numbers of alveolar macrophages present. Conclusion: Sputum cytology remains an important part of the screening programme for bronchogenic carcinoma in the public health sector of South Africa. Results confirm that sputum cytology is very specific, and automated screening improves sensitivity. Automated screening proved to be more time efficient, resulting in 83.1% reduction (p<0.0001) in the screening time spent per case by a cytotechnologist. Results confirm that the quantity of alveolar macrophages is not directly proprtional to pathology representation. Positive sputum results did however improve with sputum adequacy, but had no significant association. Recommendations from this study include adopting automated sputum screening.<br>AFRIKAANSE OPSOMMING: Agtergrond: Die verkryging van ‘n sputummonster is ‘n nie-indringende, ekonomiese ondersoek waardeur bronguskarsinoom identifiseer kan word. Nie-geoutomatiseerde sitologiese ondersoek is arbeidsintensief, tydrowend en vereis ‘n deurlopende hoë vlak van konsentrasie en fokus. Outomatisering is onlangs suksesvol geïmplementeer in ginekologiese sitologie-ondersoeke. Aangesien sputummonsters soortgelyk aan servikale monsters is, het die vraag ontstaan of sputummonsters ook geskik sou wees vir geoutomatiseerde sifting. Doelwit: Hierdie studie het verskeie doelwitte gehad: 1) Om geoutomatiseerde sifting van sputummonsters te toets deur gebruik te maak van BD Focal Point ™ Slide Profiler (FP), en te vergelyk met nie-geoutomatiseerde sputum sifting. 2) Om die sensitiwiteit en spesifisiteit van sputum in die identifikasie van bronguskarsinoom te bepaal. 3) Om vas te stel of enige kliniese, radiologiese of brongoskopiese bevindings bronguskarsinoom sou kon voorspel. 4) Om die belang van ‘n verteenwoordigende monster te bepaal. Metode: ‘n Prospektiewe studie van die pasiënte wat die Divisie van Pulmonologie by Tygerberg Hospitaal vir transbrongiale nodale aspirasie (TBNA) of ‘n transtorakale aspirasie (TTNA) vanaf Julie 2010 tot Mei 2012 bygewoon het, is gedoen. ‘n Prebrongoskopiese sputum is geneem en gestuur vir prosessering. Die gekleurde skuifies is deur die FP gestuur vir geoutomatiseerde ondersoek. Indien die sputumskuifies gekwalifiseer het vir geoutomatiseerde sifting, is hulle in die groep vir ondersoek ingesluit. ‘n Korrelasiestudie, om die sputumresultate te evalueer, is uitgevoer deur die TBNA/TTNA bevindings as standaard te gebruik. Resultate: Vir hierdie studie is 108 sputummonsters ingesluit. Vanuit die 84.3% maligne (n=91) en 15.7% benigne (n=17) gevalle, bevestig deur ‘n diagnostiese prosedure, het sputumsitologie ‘n sensitiwiteit van 38.5% (35/91 maligne gevalle) en ‘n spesifisiteit van 100.0% (17/17 benigne gevalle), getoon. Geoutomatiseerde sifting het ‘n beter sensitiwiteit met 94.3% (33/35 maligne gevalle), terwyl nie-geoutomatiseerde (ondersoek) ‘n sensitiwiteit van 74.3% (26/35 maligne gevalle) wanneer met die finale resultaat vergelyk, gevind. Individuele parameters met ‘n betekenisvolle assosiasie het die teenwoordigheid van ‘n endobrongiale tumor, gedeeltelike lugwegobstruksie / stenose, ronde massa, ‘n spekuleerde massa (negatiewe assosiasie), gewigsverlies (negatiewe assosiasie) en plaveiselkarsinoom as die histologiese subtipe, ingesluit. Geskiktheid van die monster was nie so betekenisvol as wat in die hipotese gestel is nie: aangesien 85.3% van ware positief gediagnoseerde sputummonsters, maar ook 65.5% van die vals negatiewe sputummonsters, groot hoeveelhede alveolêre makrofae ingesluit het. Gevolgtrekking: Sputumsitologie bly steeds ‘n belangrike deel van die siftingsprogram vir bronguskarsinoom in die openbare gesondheidssektor in Suid-Afrika. Resultate van hierdie studie bevestig dat sputumsitologie baie spesifiek is en dat geoutomatiseerde sifting die sensitiwiteit verbeter. Ge-outomatiseerde sifting het bewys dat dit meer tydsbesparend is, met ‘n 83.1% vermindering (p<0.0001) in die siftingstyd wat deur een sitotegnoloog per geval bestee word. Resultate het bevestig dat die hoeveelheid alveolêre makrofae nie direk proporsioneel verwant is tot die patologie nie. Hoe meer verteenwoordigend die sputummonster was, hoe groter was die kanse om ‘n akkurate positiewe diagnose te maak. Die assosiasie van die geskiktheid van die sputummonster en die positiewe resultate het egter nie ‘n statisties betekenisvolle resultaat getoon nie. Aanbevelings vir hierdie studie sluit in die aanwending van geoutomatiseerde sputumondersoeke.

&Scaron;irom sveta, karcinom bronha je i dalje vodeći po incidenci i mortalitetu, sa 2,1 milion novih slučajeva i predviđenih 1,8 smrtnih ishoda u 2018. godini. Karcinom bronha predstavlja skoro petinu (18,4%) svih smrtnih ishoda od karcinoma. Istraživanje je sprovedeno kao retrospektivna studija za period 2010-2016 godine. Svi podaci potrebni za sprovođenje ovog istraživanja direktno su prikupljeni iz zdravstvenog informacionog sistema i registra za karcinom bronha Instituta za plućne bolesti Vojvodine (IPBV), koji je referentna ustanova za pacijente sa karcinomom bronha za celu Autonomnu Pokrajinu Vojvodinu. Cilj rada je bio da se utvrdi uticaj demografskih i kliničko-patololo&scaron;kih karakteristika na ukupno vreme preživljavanja kod bolesnika sa karcinomom bronha, kao i da se izradi geoprostorna analiza incidencije i mortaliteta od karcinoma bronha na teritoriji Vojvodine. Podaci o broju novoobolelih i broju umrlih pacijenata potrebni za analizu incidencije i mortaliteta prikupljeni su od lokalnih Instituta za javno zdravlje za svaki od sedam okruga. Za potrebe analize overall survivall, survival rate ukupno je obuhvaćeno 8142 bolesnika lečenih u IPBV, od kojih je nakon provere uključujućih i isključujućih kriterijuma, u konačnu analizu u&scaron;lo njih 7540.

Urađena je analiza incidencije i mortaliteta od karcinoma bronha na teritoriji AP Vojvodine i utvrđeno je da postoje značajne regionalne razlike u incidenciji i mortalitetu od karcinoma bronha na teritoriji AP Vojvodine.<br>Worldwide, lung cancer remains the leading cause of cancer incidencije and mortality, with 2.1 million new lung cancer cases and 1.8 million deaths predicted in 2018. Methodology: For the purpose of this retrospective study we collected data of 21915 patients from seven Public Health Institutes, one for each district. This data was categorized by five-year age groups during 2010&ndash;2016. Survival analysis data of 8142 patients was collected from the Institute for Pulmonary Diseases of Vojvodina Hospital Information System and the Lung Cancer Registry. The primary objective was to determine the impact on overall survival by assessing demographic and clinical pathological characteristics in these patients. The secondary objective was to analyze the incidencije and mortality of lung cancer in the region of Vojvodina. Incidencije and mortality rates were directly age-standardized to the World and Europe Standard Population. A total of 7540 patients were eligible for the survival analysis, 5456 (72.4%) males and 2084 (27.6%) females. The average survival time, including all stages and cancer types was 17.1 months for men and 23.2 months for women (p = 0.000). There was statistically significant difference in survival time by gender in subtypes of adenocarcinoma (p = 0.000), squamous cell carcinoma (p= 0.000) and microcellular carcinoma (p = 0.001). Analysis showed significant difference in survival by age (p = 0.000), cancer type (p = 0.000), stage of the disease (p = 0.000), ECOG performance status (p = 0.000), smoking status (p = 0.001), TNM stage of disease (p = 0.000) and among districts (p = 0.014). Male gender (p = 0.000), age over 60 (p = 0.000), ECOG performance status 2 and greater (p = 0.000), smoking habit (p = 0.002), lower socioeconomic status (p = 0.000), stage IV of disease (p = 0.000) and small cell lung cancer as tumor type (p = 0.000) were identified as independent prognostic factors. One-year survival in 1A stage was 78.1%, in 1B stage 73.2%, 2A stage 70.4%, 2B stage 52.1%, 3A stage 42.3%, 3B stage 28.3 %, while in stage 4 was 17.9%. Three-year survival in 1A stage was 40.8%, in 1B stage 37.5%, 2A stage 31.2%, 2B stage 21.6%, 3A stage 9.7%, 3B stage 5.5 %, while in stage 4 was 2.9%. Five-year in 1A stage is 32.1%, in 1B stage 19.3%, 2A stage 16.2%, 2B stage 13.3%, 3A stage 4.4%, 3B stage 2.6 %, while in stage 4 was 1.6%. The incidencije rate was 118.9 per 100000 for males and 43.3 per 100000 for women. The standardized incidencije rate was 65.4 per 100000 for males and 21.7 per 100000 for females. There was a statistically significant difference by districts (p = 0.001). Mortality rate was 125.1 per 100000 for males and 43.8 per 100000 for females. The standardized mortality rate was 67.6 per 100000 for males and 20.9 per 100000 for females. There was also a statistically significant difference by district (p = 0.001). There was a statistically significant difference in overall survival by gender (p = 0.000), age (p = 0.000), place of residence (p = 0.014), smoking status (p = 0.001), ECOG performance status (p = 0.000), and socioeconomic status (p = 0.000). There was also a statistically significant difference in the overall survival by tumor type (p = 0.000), stage of disease (p = 0.000), T-descriptor (p = 0.000), N-descriptor (p = 0.000), and M-descriptor (p = 0.000). One-year survival rate was 32.5%, three-year survival was 9.2%, and five-year survival rate was 5.0%. Incidencije and mortality rates data were analyzed for the territory of Vojvodina, and it was found that there were significant regional differences.

Lung cancer is the second most common type of cancer in the UK. It is termed ‘primary’ if it originates in the lungs. and ‘secondary’ if it manifests elsewhere in the body but then spreads to the lungs. The main types of primary lung cancer are small cell lung carcinoma and non-small cell lung carcinoma. Bronchial carcinoids account for up to 5% of lung cancer. These are generally small when diagnosed and occur most commonly in people under 40 years of age. Unrelated to cigarette smoking, carcinoid tumours can metastasize and a small proportion of these tumours secrete hormone-like substances that may cause specific symptoms related to the hormone being produced. Carcinoids generally grow and spread more slowly than bronchogenic cancers, and many are detected early enough to be amenable to surgical resection. Mesothelioma is a rare type of cancer that affects the pleura.
