Full textAdvances in treatment have increased the overall 5-year survival rate for childhood cancers to approximately 80%. In France, it estimated that about 50,000 adults have survived childhood cancer. However, previous studies have demonstrated that by the second decade of life, more than 60% of survivor of childhood malignancies (CCS) will suffer from at least one chronic disease related to the treatment they have received.The general objective of this thesis was to advance knowledge about the very long morbidity associated with childhood cancer, with the ultimate target to improve both the long term outcome and quality of life of survivors.Using data from the French Childhood Cancer Survivor Study (FCCSS) cohort, which includes patients treated for a solid pediatric malignancy between 1942 and 2000, we found that that mortality among CCS remained higher than the general population even after more than 40 years of the primary cancer diagnosis. A major finding of this study was that mortality attributed to adverse effects of cancer treatments (secondary primary neoplasm and circulatory disease) declined among patients treated in more recent treatment periods. We also conducted a case control study nested in the FCCSS cohort and further affirmed the role of anthracycline in the occurrence of heart failure. We demonstrated that the median heart volume that received at least 30Gy was higher among heart failure cases and that exposing small volumes of the heart (10% of the volume of the left ventricle) to at least 30Gy was associated with an elevated risk of cardiac failure. This study was the first to derive a dose response relationship based on dose-volume metrics which can be used in current clinical practice.Our results also showed that unilateral nephrectomy was associated with a high risk of renal impairment. The effect of radiation dose to the kidneys was also different among nephrectomized patients for whom any exposure to radiation was associated with an elevated risk of chronic kidney disease even at doses less than 5 Gy.Furthermore, data from the renal epidemiology and information network (REIN) registry allowed us to investigated ESKD (end stage kidney disease) related to nephrotoxic chemotherapy and/or radiation. Our registry-based study showed that ESKD related to nephrotoxic cancer treatment has been steadily increasing over the past decade in the French population. These patients experienced a much lower rate of wait-listing than matched controls with other causes of ESKD, despite similar survival on dialysis.To conclude the results of this thesis are useful to identify survivors of childhood malignancies who are at risk of developing severe long term adverse effects related to the treatment of their primary cancer. Our results could be applied in current clinical practice to help adapt current treatment strategies and improve the long-term follow-up recommendations of childhood cancer survivors

Full textIntroduction Kidney transplantation confers both survival and quality of life advantages over dialysis for most people with end-stage kidney disease (ESKD). The mortality rate on dialysis is 10-15% per year, compared with 2-4% per year post-transplantation. Short-term graft survival is related to control of the acute rejection process, requiring on-going immunosuppression. Most current immunosuppressive algorithms include one of the calcineurin inhibitors (CNI: cyclosporin or tacrolimus), an anti-metabolite (azathioprine or mycophenolate) and corticosteroids, with or without antibody induction agents (Ab) given briefly peri-transplantation. Despite this approach, between 15-35% of recipients undergo treatment for an episode of acute rejection (AR) within one year of transplantation. Transplantation is not without risk, and relative mortality rates for kidney recipients after the first post-transplant year remain 4-6 times that of the general population. Longer-term transplant and recipient survival are related to control of chronic allograft nephropathy (rooted in the interplay of AR, non-immunological factors, and the chronic nephrotoxicity of CNI) and limitation of the complications of chronic ESKD and long-term immunosuppression: cardiovascular disease, cancer and infection, which are responsible for 22%, 39% and 21% of deaths respectively. This thesis is presented as published works on the theme of immunosuppression and cancer after kidney transplantation. The work presented in the first chapters of this thesis has striven to identify, evaluate, synthesise and distil the entirety of evidence available of new and established immunosuppressive drug agents through systematic review of randomised trial data, with particular emphasis on quantifying harms of treatment. The final chapters use inception cohort data from the Australian and New Zealand Dialysis and Transplant Registry (ANZDATA), which is first validated then used to explore the risk of cancer in more detail than was possible from trial data alone. Interleukin 2 receptor antagonists Interleukin-2 receptor antagonists (IL2Ra, commercially available as basiliximab and daclizumab) are humanised or chimeric IgG monoclonal antibodies to the alpha subunit of the IL2 receptor present only on activated T lymphocytes, and the rationale for their use has been as induction agents peri-transplantation. Introduced in the mid-1990s, IL2Ra use has increased globally, and by 2003 38% of new kidney transplant recipients in the United States and 25% in Australasia received an IL2Ra. This study aimed to systematically identify and synthesise the evidence of effects of IL2Ra as an addition to standard therapy, or as an alternative to other induction agents. We identified 117 reports from 38 randomised trials involving 4893 participants. Where IL2Ra were compared with placebo (17 trials; 2786 patients), graft loss was not different at one (Relative Risk -RR 0.84; 0.64 to 1.10) or 3 years (RR 1.08; 0.71 to1.64). AR was reduced at 6 months (RR 0.66; 0.59 to 0.74) and at 1 year (RR 0.66; 0.59 to 0.74) but cytomegalovirus (CMV) disease (RR 0.82; CI 0.65 to 1.03) and malignancy (RR 0.67; 0.33 to1.36) were not different. Where IL2Ra were compared with other antibody therapy no significant differences in treatment effects were demonstrated, but IL2Ra had significantly fewer side effects. Given a 40% risk of rejection, 7 patients would need treatment with IL2Ra in addition to standard therapy, to prevent 1 patient having rejection, with no definite improvement in graft or patient survival. There was no apparent difference between basiliximab and daclizumab. Tacrolimus versus cyclosporin for primary immunosuppression There are pronounced global differences in CNI use; 63% of new kidney transplant recipients in the USA but only 22% in Australia receive tacrolimus as part of the initial immunosuppressive regimen. The side effects of CNI differ: tacrolimus is associated more with diabetes and neurotoxicity, but less with hypertension and dyslipidaemia than cyclosporin, with uncertainty about equivalence of nephrotoxicity or how these relate to patient and graft survival, or impact on patient compliance and quality of life. This study aimed to systematically review and synthesise the positive and negative effects of tacrolimus and cyclosporin as initial therapy for renal transplant recipients. We identified 123 reports from 30 randomised trials involving 4102 participants. At 6 months graft loss was reduced in tacrolimus-treated recipients (RR 0•56; 0•36 to 0•86), and this effect persisted for 3 years. The relative reduction in graft loss with tacrolimus diminished with higher levels of tacrolimus (P=0.04), but did not vary with cyclosporin formulation (P=0.97) or cyclosporin level (P=0.38). At 1 year, tacrolimus patients suffered less AR (RR 0•69; 0•60 to 0•79), and less steroid-resistant AR (RR 0•49; 0•37 to 0•64), but more insulin-requiring diabetes (RR 1•86; 1•11 to 3•09), tremor, headache, diarrhoea, dyspepsia and vomiting. The relative excess in diabetes increased with higher levels of tacrolimus (P=0.003). Cyclosporin-treated recipients experienced significantly more constipation and cosmetic side-effects. We demonstrated no differences in infection or malignancy. Treating 100 recipients with tacrolimus instead of cyclosporin for the 1st year post-transplantation avoids 12 suffering acute rejection and 2 losing their graft but causes an extra 5 to become insulin dependent diabetics, thus optimal drug choice may vary among patients. Target of rapamycin inhibitors for primary immunosuppression Target of rapamycin inhibitors (TOR-I) are among the newest immunosuppressive agents and have a novel mode of action but uncertain clinical role. Sirolimus is a macrocyclic lactone antibiotic and everolimus is a derivative of sirolimus. Both prevent DNA synthesis resulting in arrest of the cell cycle. Animal models suggested TOR-I would provide synergistic immunosuppression when combined with CNI, but early clinical studies demonstrated synergistic nephrotoxicity. Since then diverse trials have explored strategies that avoid this interaction and investigated other potential benefits. The aim of this study was to systematically identify and synthesise available evidence of sirolimus and everolimus when used in initial immunosuppressive regimens for kidney recipients. We identified 142 reports from 33 randomised trials involving 7114 participants, with TOR-I evaluated in four different primary immunosuppressive algorithms: as replacement for CNI, as replacement for antimetabolites, in combination with CNI at low and high dose, and with variable dose of CNI. When TOR-I replaced CNI (8 trials, 750 participants), there was no difference in AR (RR 1.03; 0.74 to 1.44), but creatinine was lower (WMD -18.31 umol/l; -30.96 to -5.67), and bone marrow more suppressed (leucopoenia RR 2.02; 1.12 to 3.66, thrombocytopenia RR 6.97; 2.97 to 16.36, anaemia RR 1.67; 1.27 to 2.20). When TOR-I replaced antimetabolites (11 trials, 3966 participants), AR and CMV were reduced (RR 0.84; 0.71 to 0.99 and RR 0.49; 0.37 to 0.65) but hypercholesterolaemia was increased (RR 1.65; 1.32 to 2.06). When low was compared to high-dose TOR-I, with equal CNI dose (10 trials, 3175 participants), AR was increased (RR 1.23; 1.06 to 1.43) but GFR higher (WMD 4.27 ml/min; 1.12 to 7.41). When low-dose TOR-I and standard-dose CNI were compared to higher-dose TOR-I and reduced CNI AR was reduced (RR 0.67; 0.52 to 0.88), but GFR also reduced (WMD -9.46 ml/min; -12.16 to -6.76). There was no significant difference in mortality, graft loss or malignancy risk demonstrated for TOR-I in any comparison. Generally surrogate endpoints for graft survival favoured TOR-I (lower risk of acute rejection and higher GFR) and surrogate endpoints for patient outcomes were worsened by TOR-I (bone marrow suppression, lipid disturbance). Long-term hard-endpoint data from methodologically robust randomised trials are still needed. Monoclonal and polyclonal antibody therapy for treating acute rejection Strategies for treating AR include pulsed steroids, an antibody (Ab) preparation, the alteration of background immunosuppression, or combinations of these options. In 2002, in the USA 61.4% of patients with AR received steroids, 20.4% received Ab and 18.2% received both. The Ab available for AR are not new: horse and rabbit derived polyclonal antibodies (ATG and ALG) have been used for 35 years, and a mouse monoclonal antibody (muromonab-CD3) became available in the late 1980s. These preparations remove the functional T-cell population from circulation, producing powerful saturation immunosuppression which is useful for AR but which may be complicated by immediate toxicity and higher rates of infection and malignancy. The aim of this study was to systematically evaluate and synthesise all evidence available to clinicians for treating AR in kidney recipients. We identified 49 reports from 21 randomised trials involving 1394 participants. Outcome measures were inconsistent and incompletely defined across trials. Fourteen trials (965 patients) compared therapies for 1st AR episodes (8 Ab versus steroid, 2 Ab versus another Ab, 4 other comparisons). In treating first rejection, Ab was better than steroid in reversing AR (RR 0.57; CI 0.38 to 0.87) and preventing graft loss (RR 0.74; CI 0.58 to 0.95) but there was no difference in preventing subsequent rejection (RR 0.67; CI 0.43 to 1.04) or death (RR 1.16; CI 0.57 to 2.33) at 1 year. Seven trials (422 patients) investigated Ab treatment of steroid-resistant rejection (4 Ab vs another Ab, 1 different doses Ab, 1 different formulation Ab, 2 other comparisons). There was no benefit of muromonab-CD3 over ATG or ALG in reversing rejection (RR 1.32; CI 0.33 to 5.28), preventing subsequent rejection (RR 0.99; CI 0.61 to 1.59), graft loss (RR 1.80; CI 0.29 to 11.23) or death (RR 0.39; CI 0.09 to 1.65). Given the clinical problem caused by AR, comparable data are sparse, and clinically important differences in outcomes between widely used interventions have not been excluded. Standardised reproducible outcome criteria are needed. Validity of cancer data in an end stage kidney disease registry Registries vary in whether the data they collect are given voluntarily or as a requirement of law, the completeness of population coverage, the breadth of data collected and whether data are assembled directly or indirectly through linkage to other databases. Data quality is crucial but difficult to measure objectively. Formal audit of ANZDATA cancer records has not previously taken place. The aim of this study was to assess agreement of records of incident cancer diagnoses held in ANZDATA (voluntary reporting system) with those reported under statute to the New South Wales (NSW) state Central Cancer Registry (CCR), to explore the strengths and weaknesses of both reporting systems, and to measure the impact of any disagreement on results of cancer analyses. From 1980-2001, 9453 residents received dialysis or transplantation in NSW. Records from ANZDATA registrants were linked to CCR using probabilistic matching and agreement between registries for patients with 1 or more cancers, all cancers and site-specific cancer was estimated using the kappa-statistic (κ). ANZDATA recorded 867 cancers in 779 (8.2%) registrants; CCR 867 cancers in 788 (8.3%), with κ =0.76. ANZDATA had sensitivity 77.3% (CI 74.2 to 80.2), specificity 98.1% (CI 97.7 to 98.3) if CCR records were regarded as the reference standard. Agreement was similar for diagnoses whilst receiving dialysis (κ =0.78) or after transplantation (κ =0.79), but varied by cancer type. Melanoma (κ =0.61) and myeloma (κ =0.47) were less good; lymphoma (κ =0.80), leukaemia (κ =0.86) and breast cancer (κ =0.85) were very good. Artefact accounted for 20.8% non-concordance but error and misclassification did occur in both registries. Cancer risk did not differ in any important way whether estimated using ANZDATA or CCR records. Quality of cancer records in ANZDATA are high, differences largely explicable, and seem unlikely to alter results of analyses. Risk of cancer after kidney transplantation Existing data on the magnitude of excess risk of cancer across different kidney recipient groups are sparse. Quantifying an individual transplant candidate’s cancer risk informs both pre-transplant counselling, treatment decisions and has implications for monitoring, screening and follow-up after transplantation. The aims of this study were firstly to establish the risk of cancer in the post-transplant population compared to that experienced by the general population, and secondly to quantify how excess risk varied within the transplanted population, seeking to establish meaningful absolute risk estimates for post-transplant cancer based on unalterable recipient characteristics known a priori at the time of transplantation. 15,183 residents of Australia and New Zealand had a transplant between 1963 and 2004, and were followed for a median of 7.2 years (130,186 person-years), with 1642 (10.8%) developing cancer. Overall, kidney recipients had 3 times the cancer risk, with risk inversely related to age (Standardised Incidence Ratio of 15 to 30 in children reducing to 2 in people > 65 years). Female recipients aged 25 -29 had rates of cancer (779.2/100,000) equivalent to women aged 55 - 59 from the general population. The risk pattern of lymphoma, colorectal and breast cancer was similar to the overall age trend, melanoma showed less variability across ages and prostate cancer showed no risk increase. Within the transplanted population cancer risk was affected by age differently for each sex (P=0.007), and was elevated for recipients with prior non-skin malignancy (Hazard Ratio: HR 1.40; 1.03 to 1.89), of white race (HR 1.36; 1.12 to 1.89), but reduced for those with diabetic ESKD (HR 0.67; 0.50 to 0.89) Rates of cancer in kidney recipients were similar to non-transplanted people 20 -30 years older, but risk differed across patient groups. Men aged 45 - 54 at transplantation with graft function at 10 years had a risk of cancer that varied from 1 in 13 (non-white, diabetic ESKD, no prior cancer) to 1 in 5 (white, prior cancer, ESKD from other causes).

Full textDuring embryonic kidney development, PAX2 exerts an anti-apoptotic function however its expression typically attenuates during the post-natal period. On the other hand, PAX2 aberrant expression is observed in the majority of Renal Cell Carcinomas (RCC). RCC is resistant to chemotherapy; up-regulation of anti-apoptotic genes is recognized to contribute to tumor resistance to chemotherapy. We hypothesized that the anti-apoptotic effect of the PAX2 gene that is expressed in RCC cells contributes to RCC and their resistance to chemotherapy-induced cell death.
Human embryonic kidney (HEK293) cells transfected with a PAX2 expression vector and exposed to cisplatin, were protected from apoptosis compared to control cells. Conversely, murine collecting duct cells stably transfected with PAX2 antisense cDNA had twofold increases in cisplatin-induced apoptosis. Similarly, PAX2 knockdown using PAX2 siRNA in RCC cells CAKI-1 and ACHN enhances cisplatin-induced apoptosis in vitro.
To test the combination of PAX2 expression silencing and cisplatin treatment in vivo we developed a model of renal tumors by injecting ACHN cells as a xenograft under the skin of nude mice. I showed that a PAX2 shRNA successfully knocks down PAX2 mRNA and protein levels in a RCC cell line (ACHN). ACHN cells stably transfected with shRNAs targeted against the PAX2 homeodomain, are more susceptible to cisplatin-induced caspase-3 activation than the control ACHN cell line. Furthermore, growth of subcutaneous ACHN/shPAX2 xenografts in nude mice is significantly more responsive to cisplatin therapy than control of ACHN cell tumors. This work proposes PAX2 as a potential therapeutic gene target in metastatic renal cell carcinoma and suggests that adjunctive PAX2 knockdown may enhance the efficacy of chemotherapeutic agents such as cisplatin.
Wilms tumor, the most common pediatric renal cancer, is thought to arise from a progenitor cell of the metanephric mesenchyme that fails to complete nephrogenesis. In addition to its characteristic triphasic histology, WT can exhibit myogenic differentiation. Myogenic programming during muscle development is controlled by a PAX3 transcription factor determinant for muscle development; unexpectedly PAX3 transcriptional activity has been recently identified in the embryonic mouse kidney. These observations led us to hypothesize that PAX3 plays a role during kidney development. Furthermore, we predict that if PAX3 expression is verified during renal development, PAX3 may also be expressed in Wilms tumor with a myogenic component.
I showed that PAX3 is expressed in the metanephric mesenchyme and stromal compartment of the developing mouse kidney. In a panel of 20 Wilms tumors, PAX3 was identified in tumor samples with myogenic histopathology. Furthermore, mutations of WT1 were consistently associated with PAX3 expression in Wilms tumors and modulation of WT1 expression in HEK293 cells was inversely correlated with the level of endogenous PAX3 protein.
This work supports a novel model of normal renal development in which progenitor cells of the metanephric blastema express PAX3 when targeted toward the stromal cell fate. Suppression of PAX3 is integral to the mesenchyme-to-epithelium transition, which defines the nephrogenic cell fate and may be accomplished, in part, by WT1. Conversely, failure to suppress PAX3 may account for the myogenic phenotype in a subset of WT1-negative Wilms tumors.

Full textAdult mouse organoids are promising models for kidney research. However, their characterization has not been pushed forward to a satisfying level. Here, I have generated and characterized a long-term 3D mouse organoid (tubuloid) model, which recapitulates renewal and repair, and the architecture and functionality of the adult tubular epithelia. In the future, the model will allow detailed investigations of trajectories of self-renewing cells towards both the partial recreation and malignant transformation of the kidney. Clear cell renal cell carcinoma (ccRCC) is the most common and aggressive kidney cancer. Inactivation of the Von Hippel-Lindau (VHL) tumor suppressor gene is the major driver of ccRCC. Earlier, we identified the upregulation of Wnt and Notch signaling in CXCR4+MET+CD44+ cancer stem cells (CSCs) from primary human ccRCCs. Blocking Wnt and Notch in patient-derived xenografts, organoids and non-adherent spheres using small-molecule inhibitors impaired self-renewal of CSCs and tumor growth. To mimic CSC-governed human ccRCC in genetic mouse models, I started from the generation of two double mouse mutants; β-catenin-GOF; Notch-GOF and Vhl-LOF; β-catenin-GOF. Surprizingly, I observed neither tumors or tumor precursor lesions nor higher cell proliferation rates in the mutant kidneys. Further analyses revealed that the mutant mice displayed features of chronic kidney disease (CKD). Thus, β-catenin-GOF; Notch-GOF and Vhl-LOF; β-catenin-GOF mouse mutants did not develop kidney tumors under the given experimental conditions.

Full textThe therapeutic management of renal tumors has changed considerably in recent years with the advent of minimally invasive therapies (such as percutaneous radiofrequency) that maximize nephron savings, improves patient comfort with efficiency comparable to surgical oncology treatments reference. The next step would be to propose transcutaneous treatment (HIFU, stereotactic radiotherapy ...) as efficient with optimized morbidity and mortality.The objective of this work in the context of the LIIE of CERIMED (Aix-Marseille Université) and CRCHUM (Université de Montréal) was to develop an alternative to percutaneous renal radiofrequency we use in clinical practice Marseille for over 10 years and has proved its worth. This alternative must be capable of treating renal masses with a level of effectiveness and complication rates at least equal to the RFA, by applying transcutaneous physical agents without percutaneous approach (project KITT (Kidney Tracking Tumor)). This requires the design of technical point detection in real time of the renal tumor.We were able to develop a reliable identification algorithm that has yet to be optimized (speed of calculation) and be validated on a model that is not yet available. Work optimization and validation of segmentation algorithms, cross correlation merit function associated with Simplex optimization function, are underway as part of an international collaboration to French-Canadian LIIE and LIO.Even if we have not the opportunity to offer this type of treatment, our work allows to approach in order to offer them in the coming years

Full textKidney cancer is the 7th largest solid tumors in adults and its incidence is rising. The purpose of our research was to study renal carcinogenesis and to identify prognostic biomarkers in clear cell renal cell carcinoma.We used the isobaric tagging iTRAQ® to perform a relative quantification of kidney tumor proteins. After proteomic analysis, 928 constitutive proteins were identified and 346 had a modified expression in tumor compared with that of normal tissue. Pathway and integrated analyses indicated the presence of an up-regulation of the pentose phosphate pathway in aggressive tumors. In total, 14 proteins were excreted and could potentially become biomarkers. Among them, we confirmed that TGFBI was significantly associated with oncologic outcomes.To understand renal carcinogenesis, we investigated the 12p11.23 renal cancer susceptibility locus. The first step was to confirm this locus by an independent study. Then we performed a functional analysis of the 12p11.23 region in relation to RCC risk. Our results suggest rs7132434 is a functional SNP at 12p11.23 responsible for the GWAS RCC signal, and that this locus acts as an enhancer of SHARP1 expression by binding c-Jun. Further investigations will be necessary to understand the role of SHARP1 in renal carcinogenesis

Full textClear cell renal cell carcinoma (ccRCC) is a heterogeneous tumor. The metastatic rate is 50% and metastases are only rarely surgically excised. The objective of this thesis was to analyze the predictive factors of metastasis in the primary tumor on one hand; and to compare primary and metastatic phenotypes on the other hand. We combined different histopathological and genomic approaches. Considering prognostic factors, the new WHO/ISUP classification replaces the previous Fuhrman grade. The interest of tumor necrosis is also highlighted. A tumor of a certain grade with necrosis has a prognosis that is close to a tumor of higher grade without necrosis. The percentage of grade 4 cells could additionally help in stratifying patients. A significant difference in survival is observed between tumors with more than 50% grade 4 cells and tumors with less than 10%. At a molecular level, the VHL gene status (tumor suppressor gene inactivated by a double hit) could be implicated in the prognosis of patients. ccRCCs with no alteration of the gene are more aggressive tumors that need to be identified. There exists a morphological and immunohistochemical similarity between metastases and the high-grade component in corresponding primary tumors. Moreover, the chromosomal profile of metastases differs from those of the corresponding primary tumors. Recurrent cytogenetic events are observed in different metastatic sites (+2p, +3q, +5, +8q, +12, +20). The tumor heterogeneity phenomenon in primary tumors is also observed in metastases with inter- and intra- metastatic heterogeneity. The combined analysis of transcriptomic and genomic analyses of 14 specimens extracted from a single ccRCC and its metastases divided samples into three classes of sub-clones with no spatial link. We observe a multi-colonization process that implies not only one but several tumor clones that could cooperate in the metastatic process
Lawrentschuk, Nathan Leo. "Hypoxia and angiogenesis in renal cell carcinoma." Connect to thesis, 2009. http://repository.unimelb.edu.au/10187/6790.
Full textInvasive polarographic oxygen sensor measurements have demonstrated hypoxia in solid tumours and it is generally defined to occur at an oxygen tension less than ten mmHg.10 Perhaps of more importance is that hypoxia has been demonstrated to be a prognostic indicator for local control after treatment with radiotherapy in glioma, head and neck and cervical cancers.11-13 It has also been able to predict for survival and the presence of distant metastases in soft tissue sarcomas.14 Finally, the significance of hypoxia in the activation and induction of functional molecules such as hypoxia inducible factors (HIFs) and VEGF, the modulation of gene expression (e.g. carbonic anhydrase IX), increased proto-oncogene levels, activation of nuclear factors and accumulation of other proteins (e.g. TP53) although progressing, is yet to be defined.15,16
Thus, it is of clinical interest to understand the levels of hypoxia and numbers of hypoxic cell populations in tumours, particularly those resistant to radiation and chemotherapy. In doing so clinicians and researchers may formulate more accurate prognostic information and develop treatments targeting hypoxic cells. Renal cell carcinoma (RCC) is a tumour resistant to radiation and chemotherapy that is yet to have its oxygen status investigated.
Although the “gold standard” of oxygen tension measurement is the Polarographic Oxygen Sensor (POS or Eppendorf pO2 histograph), non-invasive means of measuring oxygen status via imaging, immunohistochemistry or serum tumour markers are more practical. As highlighted by Menon and Fraker, it is imperative that reliable, globally usable, and technically simplistic methods be developed to yield a consistent, comprehensive, and reliable profile of tumour oxygenation. Until newer more reliable techniques are developed, existing independent techniques or appropriate combinations of techniques should be optimized and validated using known endpoints in tumour oxygenation status and/or treatment outcomes.17
Hanahan and Weinberg 18 surmised that the field of cancer research has largely been guided by a reductionist focus on cancer cells and the genes within them- a focus that has produced an extraordinary body of knowledge. Looking forward in time, they believe that progress in cancer research would come from regarding tumours as complex tissues in which mutant cancer cells have conscripted and subverted normal cell types (endothelial cells, immune cells, fibroblasts) to serve as active collaborators in their neoplastic agenda. The interactions between the genetically altered malignant cells and these supporting coconspirators will prove critical to understanding cancer pathogenesis and to the development of novel, effective therapies.18
Essentially, the background outlined here not only highlights the core aim of this thesis: to better understand the oxygen status of renal cell carcinoma and the relationship of this to angiogenesis so that better targeted therapies may be pursued in the future; but it also places this research in the context of the future proposed by Hanahan and Weinberg,18 by clearly focusing on collaborators in the neoplastic agenda, rather than just tumour cells themselves, to better understand RCC.

Full textBACKGROUND AND AIMS: The improvement in the survival rates of cancer patients due to the new oncological and biological agents has led to an increase in those who develop kidney diseases. It is now well known that chronic kidney disease (CKD) and cancer are connected in several ways. However, the overall incidence and prevalence of CKD in cancer patients are still uncertain, but much evidence suggests that the risk is high and increasing. The purpose of the study is to provide data on the prevalence and incidence of CKD in patients included in the Cancer Registry of the province of Reggio Emilia from January 1st to December 31st 2016. METHODS: single-center, observational and retrospective study. For all patients included, data on sex, age, ethnicity, serum creatinine and related eGFR, type and number of tumors, diagnosis of diabetes mellitus were collected. The main cancer sites considered were breast, colorectal, lungs, pancreas, stomach, prostate, lymphomas and leukemias. An eGFR ≥ 60 ml/min1.73m2 was indicative of a normal kidney function, while an eGFR <60 ml/min/1.73m2 as kidney impairment. All the eGFR data were calculated not only with the CKD-EPI formula, now recognized as the reference formula for estimating eGFR in the general population, but also with the Wright formula which seems to provide the best evaluation in cancer patients. RESULTS: 4254 patients with a cancer diagnosis were identified between January 1st and December 31st 2016; of these, 171 patients were excluded due to lack of data. Of the remaining 4083 patients, 776 (19%) had at least an eGFR value <60 mL/min/1.73m2 prior to cancer diagnosis and 497 patients (11.7%) were identified as affected by CKD. The prevalence of CKD was 4.4% (186 patients) calculated in the following 24 months from cancer diagnosis. For both cohorts of patients (pre-existing CKD and CKD diagnosed at the time of cancer diagnosis), descriptive analyzes were conducted related to personal and clinical data. Referring to the CKD-EPI formula, in patients with pre-existing CKD (497 patients), the mean age was 81 years, 53.7% were men, 18.3% had a known diagnosis of type 2 diabetes mellitus, 3.6% of these patients had 2 or more cancer diagnosis in the study period. 44.3% were alive at the end of the follow-up (December 31st, 2018). Using Wright formula, 504 patients with CKD already present at the time of cancer diagnosis were identified; these patients had an average age of 82 years and in 55.4% of cases were men; 18.8% had type 2 diabetes mellitus and 3.8% had 2 or more cancer diagnosis. CONCLUSIONS: Knowledge of association between CKD and cancer is critically relevant information. Therefore, the rapid evolution of treatments and the diagnostic anticipation have changed the risk and prognostic factors of kidney diseases in cancer patients. Application of measures to reduce the risk progression of CKD could improve the clinical outcomes high risk cancer patients.

Full textA dimercaptosuccinic acid (DMSA) scintigraphy is used to test for pyelonephritis, an inflammation of the kidneys with risk of renal scarring. Aiming to investigate if DMSA scan after pyelonephritis in children is justified, we calculated the general cancer risk, the specific increased renal cancer risk, the number of discovered renal scarring and potential differences between the sexes. The method was retrospective and quantitative and data was based on results from DMSA scans of children aged 0-2 years. From the original set of 91 children (52 girls, 39 boys), 16 were excluded. Of the remaining 75, six (8 %) had renal scarring; with an average age of 9,2 months, and there was no significant difference between sex and renal parenchymal damage (p=0,0246). The mean activity from a DMSA scan equaled an effective dose of 0.69 mSv, with general cancer versus renal cancer risk being 0.01-0.014 and 0.00019, respectively. Even though only a few children develop renal scarring, there is still a risk of complications. Renal scarring is therefore important to discover. The increased risk for cancer and renal cancer after a DMSA scan is low. The benefits (discovering renal scarring) are greater than the risk (radiation), making the DMSA scan justified.

Full textMetastatic RCC resistant to tyrosine kinase inhibitors are amenable to new therapies based on immune checkpoint blockade (ICB). However, ICB induces responses in a sizeable minority of patients and efforts are ongoing in order to identify mechanisms driving resistance. ICB compromise the integrity of the intestinal barrier, hereby affecting the composition of the intestinal microbiome, thereby promoting either the intestinal accumulation or the translocation of immunogenic commensals capable of modulating the systemic immune tone and reprogramming the tumor microenvironment. To address whether distinct microbial patterns of the intestinal microbiome could account for the resistance to ICB in RCC, during my PhD I showed in a cohort of 249 patients with cancers treated with ICB that antibiotic (ATB) prescription in a therapeutic window of -2 months up to +1 month after starting ICB significantly decreased progression-free survival (PFS) and overall survival (OS) compared to patients without ATB. We confirmed this data analyzing 121 RCC treated with ICB at Gustave Roussy and 239 NSCLC treated with ICB at Memorial Sloan Kettering Cancer Center. We validated that ATB-related dysbiosis decreases activity of ICB. More precisely, patients in RCC ATB group treated with ICB had a higher rate of primary progressive disease. Subsequently, we prospectively analyzed the fecal microbiomes of 100 patients with tumours amenable to anti-PD-1 mAb using quantitative metagenomics (MG) by shotgun sequencing. We demonstrated that gut bacteria present before anti-PD-1 therapy was consistently different between patients who responded (R) to treatment and patients who did not (NR). In R we observed an overrepresentation of un- and classified Firmicutes. The commensal most significantly associated with favorable clinical outcome and PFS was Akkermansia muciniphila. Within a large cohort of RCC patients (n = 85) treated in the NIVOREN study with anti-PD-1 Ab at Gustave Roussy, we analyzed the fecal microbiome of 69 patients. Specific MG-fingerprints were related to best responses and PFS. A. muciniphila and Bacteroides spp were more abundant in R (Derosa et al. ASCO Merit Award 2018). To validate the relevance of these findings, we brought up two major lines of evidence. First, we demonstrated that in NSCLC patients, the presence of specific IFNγ+ memory CD4+ and CD8+ T cells toward A. muciniphila predicted a longer PFS. Secondly, fecal microbiota transplantation (FMT) was performed using patient feces to recolonize germ-free or ATB-treated mice in two tumor models (MCA-205 and RENCA, the renal cell carcinoma model). Feces from R conveyed a stronger immune response against the tumor compared to feces from NR. Next, in MCA-205 model oral supplementation with A. muciniphila post-FMT with NR feces restored the efficacy of PD-1 Abs. In this setting, dendritic cells secreted more IL-12, increasing the recruitment of CCR9+CXCR3+CD4+ T lymphocytes from the mesenteric lymph nodes into tumor beds as well as an increase of CD4+/Treg ratio within the tumor bed of mice co-treated with anti-PD-1 mAb and A. muciniphila. Finally, we showed that oral supplementation with Bacteroides (B. salyersiae but not B. xylanisolvens) or A. muciniphila could restore the efficacy of ICB in "unfavorable/dysbiotic" FMT. The discovery of immunogenic bacteria capable of predicting and increasing clinical benefit of ICB will help for the development of novel biomarker tools and a future therapeutic concept, whereby treatment of cancer can be improved by the modulation of gut microbiome

Full textLas enfermedades renales se derivan de defectos congénitos, lesiones renales agudas (AKI) o enfermedad renal crónica (CKD), entre otras causas. La lesión renal de isquemia / reperfusión (IRI), que se encuentra en muchas situaciones clínicas, es una de las causas principales de AKI que causan lesiones y muerte de células epiteliales del túbulo proximal (PTEC). La gravedad de AKI y la capacidad de regenerarse después de la lesión son determinantes importantes de la morbilidad y mortalidad de los pacientes en un entorno hospitalario. Los hombres son más propensos a la enfermedad renal aguda y crónica y avanzar hasta la enfermedad renal en fase final (ESRD) que las mujeres y actualmente se acepta que los andrógenos, y no la ausencia de estrógenos, son responsables de esto. Se acepta que la regeneración por PTEC superviviente es el mecanismo predominante de reparación/regeneración después de lesiones tubulares isquémicas en el riñón adulto de mamífero. Las PTEC son también el lugar donde se origina el carcinoma de células renales de células claras (ccRCC) en humanos. El ccRCC también presenta diferencias de sexo, con los hombres que tienen casi el doble de la incidencia de las mujeres a nivel mundial. Esto condujo a la hipótesis de que la regeneración después de lesiones renales y el desarrollo de ccRCC podrían compartir repertorios de expresión génica similares. Los andrógenos son muy relevantes en el desarrollo de los riñones, lo que sugiere que la regeneración y el cáncer en las células del túbulo proximal pueden recapitular, en parte, los programas dependientes de los andrógenos en el desarrollo del riñón. En este proyecto, hemos querido encontrar dianas que participen en la regeneración renal y en procesos de cáncer renal. Además, nos interesó estudiar la regulación de la hormona sexual en estas vías. Se realizaron análisis detallados de datos transcriptómicas de un modelo porcino de AKI. Se determinaron genes que expresaban un dimorfismo sexual en toda la IRI y se validaron dianas en muestras humanas. Además, se determinaron los conjuntos de genes implicados en la IRI y se caracterizaron de forma sexual y de tiempo. Encontramos que los grupos genéticos relacionados con los procesos de regeneración eran más activos en las mujeres que en los hombres. Además, la respuesta inmune a la lesión fue mayor en hombres que en mujeres. Después, hemos vinculado los procesos de regeneración con ccRCC mediante la superposición entre los análisis del transcriptomas AKI y ccRCC. Además, encontramos diferencias importantes entre los transcriptomas de riñón de ratón y de cerdo tras la lesión renal. Se estableció un modelo in vitro de IRI renal y se permitió validar parcialmente los hallazgos in vivo. Entre otros, observamos que durante la IRI renal, STAT3 está regulado por la fosforilación de diferentes residuos. Este estudio constituye una caracterización extensiva de las diferencias de sexo existentes durante la IRI renal. Ofrece una plantilla para caracterizar más las diferencias de sexo en enfermedades renales a nivel molecular.
Kidney diseases arise from congenital defects, acute kidney injury (AKI) or chronic kidney disease (CKD), among other causes. Renal ischemia/reperfusion injury (IRI), which is faced in many clinical situations, is a major cause of AKI leading to injury and death of proximal tubule epithelial cells (PTEC). The severity of AKI and the capacity to regenerate after injury are important determinants of patient morbidity and mortality in the hospital setting. Men are more prone to acute and chronic kidney disease and to progress to end-stage renal disease (ESRD) than women and it is currently accepted that androgens, and not the absence of estrogens, are responsible for that. It is accepted that regeneration by surviving PTEC is the predominant mechanism of repair/regeneration after ischemic tubular injury in the adult mammalian kidney. PTEC are also the site where the clear cell renal cell carcinoma (ccRCC) originates in humans. ccRCC also exhibits sex differences, with males having almost twice the incidence of females globally. This led to the hypothesis that regeneration after kidney injury and ccRCC development might share similar gene expression repertoires. Androgens are very relevant in kidney development, which suggests that regeneration and cancer in proximal tubule cells might recapitulate, in part, androgen-dependent programs in kidney developmental. In this project, we aimed to find targets that participate in renal regeneration and in renal cancer processes. Moreover, we were interested to study the sex hormone regulation of these pathways. Thorough analyses of transcriptomic data from a porcine model of AKI was performed. We determined genes that expressed a sexual dimorphism throughout IRI and we validated theses targets in human samples. Furthermore, we determined the gene sets involved in IRI and characterize them in a time and sex manner. We found that gene sets related to regeneration processes were more active in females than in males. Also, the immune response at injury was higher in males than in females. Afterwards, we linked regeneration processes with ccRCC by the overlap between AKI and ccRCC transcriptome analyses. Besides, we found major differences between the mouse and the pig kidney transcriptomes upon renal injury. An in vitro model of renal IRI was established and allowed to partially validate the in vivo findings. Among others, we observed that during renal IRI, STAT3 is regulated by phosphorylation of different residues. This study constitutes an extensive characterization of the sex differences that exist during renal IRI. It offers a template for further characterization of sex differences in kidney diseases at the molecular level.

Full textObjective: Approximately 30% of patients with metastatic renal cancer are resistant to targeted therapy agents. The other patients will eventually develop long-term therapeutic resistances. An improvement in the clinician's ability to predict therapeutic response before treatment initiation could improve patients' prognosis. The aim of our projet was to develop a patient-derived xenograft models to be able to test the sensibility of each patient's renal tumor cells to the different available targeted therapy agent prior to treatment.Methods: The chicken embryo chorioallantoic membrane has been the base of our model. In a first phase of our work, a xenograft of human kidney tumor cells has been carried out in order to verify that the histologic and phenotypic characteristics of the original tumors were preserved in the xenografts performed on our model. As a second step, fragments of the kidney tumor speciments of 5 patients undergoing cytoreductive nephrectomy in our hospital center were grafted on our model (> 60/patient). Different targeted therapy agents were tested on the xenografts we performed.Results: The histopathologic and phenotypic characteristics of the original renal tumors were preserved in our xenografts. There was intra-tumor spatial heterogeneity in terms of sensitivity in different targeted therapy agents. There was also a nucleotide polymorphism within the different regions of each renal tumor.Conclusion: This patient-derived renal xenograft model could be useful prior to treatment for the evaluation of each patients'renal tumor cells to the different available targeted therapy agents. This model could make it possible to personalize the treatment of each metastatic kidney cancer patient, prior to systemic treatment. A prospective evaluation of our model could help assess the potential clinical benefits of its use
