RESUMO

BACKGROUND: The optimal perioperative chemotherapy for patients with muscle-invasive bladder cancer is not defined. The VESPER (French Genito-Urinary Tumor Group and French Association of Urology V05) trial reported improved 3-year progression-free survival with dose-dense methotrexate, vinblastine, doxorubicin and cisplatin (dd-MVAC) versus gemcitabine and cisplatin (GC) in patients who received neoadjuvant therapy, but not in the overall perioperative setting. In this Article, we report on the secondary endpoints of overall survival and time to death due to bladder cancer at 5-year follow-up. METHODS: VESPER was an open-label, randomised, phase 3 trial done at 28 university hospitals or comprehensive cancer centres in France, in which adults (age ≤18 years and ≤80 years) with primary bladder cancer and histologically confirmed muscle-invasive urothelial carcinoma were randomly allocated (1:1; block size four) to treatment with dd-MVAC (every 2 weeks for a total of six cycles) or GC (every 3 weeks for a total of four cycles). Overall survival and time to death due to bladder cancer (presented as 5-year cumulative incidence of death due to bladder cancer) was analysed by intention to treat (ITT) in all randomly assigned patients. Overall survival was assessed by the Kaplan-Meier method with the treatment groups compared with log-rank test stratified for mode of administration of chemotherapy (neoadjuvant or adjuvant) and lymph node involvement. Time to death due to bladder cancer was analysed with an Aalen model for competing risks and a Fine and Gray regression model stratified for the same two covariates. Results were presented for the total perioperative population and for the neoadjuvant and adjuvant subgroups. The trial is registered with ClinicalTrials.gov, NCT01812369, and is complete. FINDINGS: From Feb 25, 2013, to March 1, 2018, 500 patients were randomly assigned, of whom 493 were included in the final ITT population (245 [50%] in the GC group and 248 [50%] in the dd-MVAC group; 408 [83%] male and 85 [17%] female). 437 (89%) patients received neoadjuvant chemotherapy. Median follow-up was 5·3 years (IQR 5·1-5·4); 190 deaths at the 5-year cutoff were reported. In the perioperative setting (total ITT population), we found no evidence of association of overall survival at 5 years with dd-MVAC treatment versus GC treatment (64% [95% CI 58-70] vs 56% [50-63], stratified hazard ratio [HRstrat] 0·79 [95% CI 0·59-1·05]). Time to death due to bladder cancer was increased in the dd-MVAC group compared with in the GC group (5-year cumulative incidence of death: 27% [95% CI 21-32] vs 40% [34-46], HRstrat 0·61 [95% CI 0·45-0·84]). In the neoadjuvant subgroup, overall survival at 5 years was improved in the dd-MVAC group versus the GC group (66% [95% CI 60-73] vs 57% [50-64], HR 0·71 [95% CI 0·52-0·97]), as was time to death due to bladder cancer (5-year cumulative incidence: 24% [18-30] vs 38% [32-45], HR 0·55 [0·39-0·78]). In the adjuvant subgroup, the results were not conclusive due to the small sample size. Bladder cancer progression was the cause of death for 157 (83%) of the 190 deaths; other causes of death included cardiovascular events (eight [4%] deaths), deaths related to chemotherapy toxicity (four [2%]), and secondary cancers (four [2%]). INTERPRETATION: Our results on overall survival at 5 years were in accordance with the primary endpoint analysis (3-year progression-free survival). We found no evidence of improved overall survival with dd-MVAC over GC in the perioperative setting, but the data support the use of six cycles of dd-MVAC over four cycles of GC in the neoadjuvant setting. These results should impact practice and future trials of immunotherapy in bladder cancer. FUNDING: French National Cancer Institute.

RESUMO

PURPOSE: Variant histology or divergent differentiation (VH/DD) of urothelial carcinoma (UC) may impact outcomes after neoadjuvant chemotherapy (NAC) in muscle-invasive bladder cancer. Our aim was to assess the pathological response and progression-free survival (PFS) of patients with VH/DD in the prospective VESPER clinical trial. MATERIALS AND METHODS: This post hoc study included 300 NAC-treated patients with available transurethral diagnostic slides. Presence and percentage of VH/DDs were reviewed. For pathological response, logistic regression models were computed to measure association with VH/DD. For PFS, the associations were estimated in Cox proportional hazard regression model. All models were adjusted for randomization arm. RESULTS: VH/DD was identified in 177/300 patients (59%) and was predominant (≥50%) in 85/177. Compared to pure UC, VH/DD (≥10% or ≥50%) was not associated with a difference in proportion of complete pathological response (ypT0N0; OR adjusted: 0.79, 95% CI 0.49-1.29), downstaging (≤ypT1N0; OR adjusted: 0.62, 95% CI 0.37-1.02), or with an increased hazard of PFS (HR adjusted: 1.24, 95% CI 0.83-1.85). However, comparing specific VH/DD to pure UC, nested subtype was associated with decreased odds of complete pathological response (OR adjusted: 0.33, 95% CI 0.12-0.88) and downstaging (OR adjusted: 0.30, 95% CI 0.13-0.74), and an increased hazard of PFS was observed for UC with ≥ 50% squamous differentiation (HR adjusted: 2.11, 95% CI 1.01-4.38) or micropapillary subtype (HR adjusted: 2.03, 95% CI 0.98-4.22). CONCLUSIONS: In the VESPER trial, we did not observe evidence for association of VH/DD with outcomes after NAC, but the specific presence of a predominant squamous differentiation or micropapillary subtype may be associated with shorter PFS.

RESUMO

BACKGROUND: Severe chemotherapy-related toxicities are frequent among older patients. The Chemotherapy Risk Assessment Scale for High-Age Patients (CRASH) and the Cancer and Aging Research Group Study (CARG) score were both developed to predict these events. PATIENTS AND METHODS: The objective of this study was to evaluate the scores' predictive performance in a prospective cohort, which included patients aged 70 years and older referred for a geriatric assessment prior to chemotherapy for a solid tumor. The main endpoints were grades 3/4/5 toxicities for the CARG score and grades 4/5 hematologic toxicities and grades 3/4/5 non-hematologic toxicities for the CRASH score. RESULTS: A total of 248 patients were included, of which 150 (61%) and 126 (51%) experienced at least one severe adverse event as defined respectively in CARG and CRASH studies. The incidence of adverse events was not significantly greater in the intermediate and high-risk CARG groups than in the low-risk group (odds ratio (OR) [95% CI] = 0.3 [0.1-1.4] (P = .1) and 0.4 [0.1-1.7], respectively). The area under curve (AUC) was 0.55. Similarly, the incidence of severe toxicities was no greater in the intermediate-low, intermediate-high, and high-risk CRASH groups than in the low-risk CRASH group (OR [95%CI] = 1 [0.3-3.6], 1 [0.3-3.4], and 1.5 [0.3-8.1], respectively). The AUC was 0.52. The type of cancer, performance status, comorbidities, body mass index, and MAX2 index were independently associated with grades 3/4/5 toxicities. CONCLUSION: In an external cohort of older patients referred for a pretherapeutic GA, the CARG and CRASH scores were poor predictors of the risk of chemotherapy severe toxicities.

RESUMO

PURPOSE: to assess the respective outcomes of patients with localized muscle-invasive bladder cancer (MIBC) treated by either radical cystectomy (RC) or trimodal treatment (TMT) depending on pathological response to previous neoadjuvant chemotherapy (NAC) assessed on cystectomy specimen or post-NAC transurethral resection (TURB) specimen, respectively. PATIENT AND METHODS: We retrospectively included all consecutive patients treated in one academic center with cisplatin-based NAC followed by RC or TMT for cT2-3N0M0 MIBC between 2014 and 2021. Primary endpoint was metastasis-free survival (MFS) in both treatment groups and according to pathological response to NAC. Local recurrence-free survival and conservative management failure (metastasis-free bladder-intact survival) for patients treated with TMT were assessed. RESULTS: 104 patients were included, 26 treated with TMT and 78 with RC. The rate of complete pathological response was 47.4% in patients treated with RC (ypT0) and 66.7% in patients treated with TMT (ycT0). Median follow-up was 34.9 months. Four-year MFS was 72% in both treatment groups. Four-year MFS was 85% in both ypT0 RC patients and ycT0 TMT patients. ycT0 stage was associated with low rates of intravesical recurrence and conservative management failure. CONCLUSION: Patients with post-NAC ycT0 stage treated with TMT have favorable oncological outcomes similar to those of ypT0 patients treated with RC. Assessment of complete histological response with TURB after NAC may help in selecting the best candidates for bladder preservation with TMT.

RESUMO

PURPOSE: This study aimed at describing the feasibility and oncological outcomes of standard cisplatin-based neoadjuvant chemotherapy (C-NAC) for muscle-invasive bladder cancer (MIBC) in patients aged ≥ 75 and assess the impact of baseline geriatric parameters. METHODS: This retrospective study included patients with stage cT2-4NanyM0 MIBC aged 75 and older treated with ≥ 1 cycle of C-NAC from 2011 to 2021 at a high-volume academic center. Primary outcome was overall survival (OS). Secondary outcomes were chemotherapy feasibility (administration of ≥ 4 cycles), safety, and pathological downstaging. RESULTS: Fifty-six patients were included. Median age was 79 (range 75-90). C-NAC regimen was ddMVAC in 41 patients and GC in 15. Seventy-three percent of patients received ≥ 4 cycles of C-NAC. Grade ≥ 3 toxicity was observed in 55% of patients. The febrile neutropenia rate was 7%. Thirty patients underwent cystectomy, and 13 underwent chemoradiotherapy. Three-year OS was 63%. Geriatric parameters polypharmacy, undernutrition, and age-adjusted Charlson comorbidity index ≥ 8 predicted worse OS. CONCLUSION: Standard-of-care C-NAC and local treatments are feasible in selected elderly MIBC patients, with efficacy and safety findings similar to that observed in pivotal trials with younger patients. The prognostic impact of geriatric parameters underlines the need for specialized evaluation before treatment initiation.

RESUMO

BACKGROUND: Stereotactic Body Radiation Therapy (SBRT) is an innovative modality based on high precision planning and delivery. Cancer with bone metastases and oligometastases are associated with an intermediate or good prognosis. We assume that prolonged survival rates would be achieved if both the primary tumor and metastases are controlled by local treatment. Our purpose is to demonstrate, via a multicenter randomized phase III trial, that local treatment of metastatic sites with curative intent with SBRT associated of systemic standard of care treatment would improve the progression-free survival in patients with solid tumor (breast, prostate and non-small cell lung cancer) with up to 3 bone-only metastases compared to patients who received systemic standard of care treatment alone. METHODS: This is an open-labeled randomized superiority multicenter phase III trial. Patients with up to 3 bone-only metastases will be randomized in a 1:1 ratio.between Arm A (Experimental group): Standard care of treatment & SBRT to all bone metastases, and Arm B (Control group): standard care of treatment. For patients receiving SBRT, radiotherapy dose and fractionation depends on the site of the bone metastasis and the proximity to critical normal structures. This study aims to accrue a total of 196 patients within 4 years. The primary endpoint is progression-free survival at 1 year, and secondary endpoints include Bone progression-free survival; Local control; Cancer-specific survival; Overall survival; Toxicity; Quality of life; Pain score analysis, Cost-utility analysis; Cost-effectiveness analysis and Budget impact analysis. DISCUSSION: The expected benefit for the patient in the experimental arm is a longer expectancy of life without skeletal recurrence and the discomfort, pain and drastic reduction of mobility and handicap that the lack of local control of bone metastases eventually inflicts. TRIALS REGISTRATION: ClinicalTrials.gov NCT03143322 Registered on May 8th 2017. Ongoing study.

RESUMO

INTRODUCTION: Cisplatin-based neoadjuvant chemotherapy (NAC) followed by surgery is the standard treatment for patients with non-metastatic muscle invasive bladder cancer (MIBC). Unfortunately, many patients are not candidates to receive cisplatin due to renal impairment. Additionally, no predictive biomarkers for pathological complete response (pCR) are currently validated in clinical practice. Studies evaluating immune checkpoint inhibitors in the peri-operative setting are emerging with promising results. Clinical trials are clearly required in the neoadjuvant setting in order to improve therapeutic strategies. METHODS AND ANALYSIS: Oncodistinct 004 - AURA is an ongoing multicenter phase II randomized trial assessing the efficacy and safety of avelumab single-agent or combined to different NAC regimens in patients with non-metastatic MIBC. Patients are enrolled in two distinct cohorts according to their eligibility to receive cisplatin-based NAC. In the cisplatin eligible cohort, patients are randomized in a 1:1 fashion to receive avelumab combined with cisplatin-gemcitabine or with dose-dense methotrexate-vinblastine-doxorubicin-cisplatin. In the cisplatin ineligible cohort, patients are randomized at a 1:1 ratio to paclitaxel-gemcitabine associated to avelumab or avelumab alone. Primary endpoint is pCR. Secondary endpoints are pathological response and safety. ETHICS AND DISSEMINATION: The study is approved by ethics committee from all participating centers. All participants provide informed consent prior inclusion to the study. Once completed, results will be published in peer-reviewed journals. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov (NCT03674424).

RESUMO

BACKGROUND: Patients with advanced urothelial carcinoma that progresses after platinum-based chemotherapy have a poor prognosis and limited treatment options. METHODS: In this open-label, international, phase 3 trial, we randomly assigned 542 patients with advanced urothelial cancer that recurred or progressed after platinum-based chemotherapy to receive pembrolizumab (a highly selective, humanized monoclonal IgG4κ isotype antibody against programmed death 1 [PD-1]) at a dose of 200 mg every 3 weeks or the investigator's choice of chemotherapy with paclitaxel, docetaxel, or vinflunine. The coprimary end points were overall survival and progression-free survival, which were assessed among all patients and among patients who had a tumor PD-1 ligand (PD-L1) combined positive score (the percentage of PD-L1-expressing tumor and infiltrating immune cells relative to the total number of tumor cells) of 10% or more. RESULTS: The median overall survival in the total population was 10.3 months (95% confidence interval [CI], 8.0 to 11.8) in the pembrolizumab group, as compared with 7.4 months (95% CI, 6.1 to 8.3) in the chemotherapy group (hazard ratio for death, 0.73; 95% CI, 0.59 to 0.91; P=0.002). The median overall survival among patients who had a tumor PD-L1 combined positive score of 10% or more was 8.0 months (95% CI, 5.0 to 12.3) in the pembrolizumab group, as compared with 5.2 months (95% CI, 4.0 to 7.4) in the chemotherapy group (hazard ratio, 0.57; 95% CI, 0.37 to 0.88; P=0.005). There was no significant between-group difference in the duration of progression-free survival in the total population (hazard ratio for death or disease progression, 0.98; 95% CI, 0.81 to 1.19; P=0.42) or among patients who had a tumor PD-L1 combined positive score of 10% or more (hazard ratio, 0.89; 95% CI, 0.61 to 1.28; P=0.24). Fewer treatment-related adverse events of any grade were reported in the pembrolizumab group than in the chemotherapy group (60.9% vs. 90.2%); there were also fewer events of grade 3, 4, or 5 severity reported in the pembrolizumab group than in the chemotherapy group (15.0% vs. 49.4%). CONCLUSIONS: Pembrolizumab was associated with significantly longer overall survival (by approximately 3 months) and with a lower rate of treatment-related adverse events than chemotherapy as second-line therapy for platinum-refractory advanced urothelial carcinoma.

RESUMO

Combining quality and quantity of life is one of the challenges of geriatric oncology This requires early diagnosis and a full medical, psychological and social assessment of the patient. The aim of this assessment is to take a global approach to the patient's care management, to take into consideration his or her own opinion and to define a suitable treatment. Once the treatment has been established, the setting up of follow-up care for any comorbidities and symptoms, as well as the putting in place of help where needed, can help to improve quality of life.

RESUMO

Although human epidermal growth factor receptor 2 (HER2) may represent a therapeutic target, its evaluation in urothelial carcinoma of the bladder does not rely on a standardized scoring system by immunohistochemistry or fluorescent in situ hybridization (FISH), as reflected by various methodology in the literature and clinical trials. Our aim was to improve and standardize HER2 amplification detection in bladder cancer. We assessed immunohistochemical criteria derived from 2013 American Society of Clinical Oncology (ASCO)/College of American Pathologists (CAPs) guidelines for breast cancer and investigated intratumoral heterogeneity in a retrospective multicentric cohort of 188 patients with locally advanced urothelial carcinoma of the bladder. Immunohistochemistry was performed on 178 primary tumors and 126 lymph node metastases, eligible cases (moderate/strong, complete/incomplete membrane staining) were assessed by FISH. HER2 overexpression was more frequent with 2013 ASCO/CAP than 2007 ASCO/CAP guidelines (p < 0.0001). The rate of positive HER2 FISH was similar between primary tumor and lymph node metastases (8%). Among positive FISH cases, 48% were associated with moderate/strong incomplete membrane staining that were not scored eligible for FISH by 2007 ASCO/CAP criteria. Among 3+ immunohistochemistry score cases, 67% were associated with HER2-positive FISH. Concordance between primary tumors and matched lymph node metastases was moderate for immunohistochemistry (κ = 0.54 (CI 95%, 0.41-0.67)) and FISH (κ = 0.50 (CI 95%, 0.20-0.79)). HER2-positive FISH was more frequent in micropapillary carcinomas (12%) and carcinoma with squamous differentiation (11%) than in pure conventional carcinoma (6%). Intratumoral heterogeneity for HER2 immunohistochemistry was observed in 7% primary tumor and 6% lymph node metastases; 24% positive HER2 FISH presented intratumoral heterogeneity. Our study suggests that HER2 evaluation should include an immunohistochemistry screening step with eligibility for FISH including incomplete/complete and moderate/strong membrane staining. Spatial or temporal intratumoral heterogeneity prompts to perform evaluation on both tumor and lymph node, and for each histological variant observed.

RESUMO

This study's purpose was to have residents evaluate Radiation Oncology (RO) theoretical teaching practices in France. An anonymous electronically cross-functional survey on theoretical teaching practices in the RO residents was conducted by (i) collecting data from residents in the medical faculties in France, (ii) comparing the data across practices when possible and (iii) suggesting means of improvement. A total of 103 out of 140 RO residents responded to the survey (73.5% response rate). National, inter-university, university and internships courses do not exist in 0% (0), 16.5% (17), 53.4% (55) and 40.8% (42) of residents, respectively. Residents need additional training due to the shortage of specialised postgraduate degree training (49.5% (51)), CV enhancement to obtain a post-internship position (49.5% (51)) or as part of a career plan (47.6% (49)). The topics covered in teaching to be improved were the following: basic concept 61.2% (63), advanced concept 61.2 (63) and discussion of frequent clinical cases 50.5% (52). The topics not covered in teaching to be improved were the following: the development of career (66.0% (68)), medical English (56.3% (58)), the organisation of RO speciality (49.5% (51)) and the hospital management of RO department (38.8% (40)). This is the first national assessment of theoretical teaching of RO residents in France.

RESUMO

Medical treatment of metastatic kidney cancer: targeting the tumor micro-environment. Metastatic kidney cancer has a poor prognosis. Progress has been made in recent years with the development of drugs targeting the tumor microenvironment, namely angiogenesis and immune infiltrate. First-line drugs inhibit neo-angiogenesis and target the vascular endothelial growth factor receptor. Nivolumab is an anti-PD1 human monoclonal antibody that, by binding to its target, interrupts binding with its ligand PD-L1 and thus restores T-cell activation and destroys the tumor cell. The median overall survival of patients is about 2 years.


Traitements médicaux des cancers du rein métastatiques : le ciblage de l'environnement tumoral. Le cancer du rein métastatique a un pronostic sombre. Des progrès ont néanmoins été réalisés au cours des dernières années avec le développement de médicaments ciblant le microenvironnement tumoral, à savoir la néo-angiogenèse et plus récemment l'infiltrat lymphocytaire. Les médicaments utilisés en première intention inhibent la néo-angiogenèse et ont pour cible le récepteur du vascular endothelial growth factor. Le nivolumab est un anticorps monoclonal humain anti-PD1 qui, en se fixant sur sa cible, interrompt la liaison avec son ligand PD-L1 et permet ainsi de restaurer l'activation du lymphocyte T et de détruire la cellule tumorale. La médiane de survie globale des patients est d'environ 2 ans.

RESUMO

PURPOSE: To investigate sunitinib in the real-life first-line treatment of metastatic renal cell carcinoma (mRCC). METHODS: SANTORIN is a French observational multicentre cohort. Patients initiating sunitinib in first-line mRCC therapy were included (January 2008 to April 2010) and followed for 24 months. Data were collected from medical files. The outcomes were 24-month overall survival (OS) and progression-free survival (PFS), response and safety. RESULTS: Three hundred two patients were included: median age, 64.8 years; male, 73.2%; clear cell mRCC, 83.1%; prior nephrectomy, 85.4%; >1 metastatic sites, 64.2%; brain metastases, 6.3%; ECOG-PS ≥ 2, 9.9%. Median duration of first-line therapy with sunitinib was 10.7 months. Initial sunitinib dose was 50 mg/day for 83.4% of patients; dose reduction occurred in 65.2%. Sunitinib was discontinued in 73.2% of the patients: for progression (61.1%), death (31.2%) or adverse events (6.8%). More than half (58.3%) had grade ≥3 adverse events, mainly hypertension (12.6%) and hand-foot syndrome (12.3%). The 24-month OS and PFS rates [95%CI] were 49.5% [43.7;55.0] and 16.4% [12.5;20.9], respectively. Median OS was 23.6 months [20.2;-] and median PFS 8.4 months [7.6;9.9]. Overall best response rate was 31.1%. CONCLUSIONS: Results from this large observational study suggest that effectiveness of sunitinib in first-line mRCC as predicted by clinical trials is maintained in real-life clinical practice. The expected benefit in poor-prognosis patients that were not evaluated in the pivotal clinical trial remains; however, questionable and long-term safety monitoring is still warranted.

RESUMO

BACKGROUND: The ovarian yolk sac tumor (OYST) is a very rare malignancy arising in young women. Our objective was to determine whether an early decline in serum alpha-fetoprotein (AFP) during chemotherapy has a prognostic impact. METHODS: This retrospective study is based on prospectively recorded OYST cases at Gustave Roussy (Cancer Treatment Center). Survival curves were estimated using the Kaplan-Meier method. The serum AFP decline was calculated with the formula previously developed and validated in male patients with poor prognosis non-seminomatous germ cell tumors. Univariate and multivariate analyses were performed using the log-rank test and logistic regression, respectively. RESULTS: Data on AFP were available to calculate an early AFP decline in 57 patients. All patients had undergone surgery followed by chemotherapy. The 5-year overall survival (OS) and event-free survival (EFS) rates were 86% (95% CI: 74%-93%) and 84% (95% CI: 73%-91%), respectively. The disease stage, presence of ascites at presentation, use of the BEP regimen, serum AFP half-life and an early AFP decline were significantly predictive factors for OS and EFS in the univariate analysis. The OS rate was 100% and 49% (95% CI: 26%-72%) in patients with a favorable AFP decline and in those with an unfavorable decline, respectively (p<0.001). In the multivariate analysis, only the presence of ascites at diagnosis (RR=7.3, p=0.03) and an unfavorable early AFP decline (RR=16.9, p<0.01) were significant negative predictive factors for OS. CONCLUSIONS: An early AFP decline during chemotherapy is an independent prognostic factor in patients with OYSTs. CONFLICT OF INTEREST STATEMENT: No conflict of interest.

RESUMO

OBJECTIVE: To perform a phase II study evaluating a combination of gemcitabine and cisplatin in a population of patients with squamous cell carcinoma (SCC) of the penis and unresected locoregional lymph nodes and/or distant metastases, who had a poor prognosis with no standard of chemotherapy. PATIENTS AND METHODS: Eligible patients had histologically confirmed SCC of the penis with unresected locoregional lymph nodes and/or distant metastases, at initial diagnosis or at relapse, and measurable disease as defined by Response Evaluation Criteria in Solid Tumors (RECIST) criteria. Patients were treated with a combination of gemcitabine 1250 mg/m(2) on day 1 over 30 min and cisplatin 50 mg/m(2) on day 1 over 1 h, every 2 weeks. The primary endpoint was the objective response rate; secondary endpoints were time to progression (TTP) and overall survival (OS). RESULTS: In all, 25 patients were included in the first phase of the study between February 2004 and January 2010 and received a median of five cycles. For the intent-to-treat population, two patients (95% confidence interval [CI] 0.98-26.0) presented an objective response and 13 patients (52%) had stable disease (95% CI 35.5-76.8). The median TTP was at 5.48 months (95% CI 2.40-11.73). After a median follow-up of 26.97 months (95% CI 17.77, not reached), nine patients were still alive. The median OS and 2-year OS rate were respectively estimated at 14.98 months (95% CI 9.76-32.9) and 39.32% (95% CI 19.15-59.03). Eleven patients had a serious adverse event (44%), 24% being relied to chemotherapy. CONCLUSION: Every 2 weeks' administration of the combination of gemcitabine and cisplatin showed non-significant responses in patients with unresected locoregional or metastatic penile SCC. Despite manageable side-effects, this combination cannot be recommended as a standard of care, due to disappointing response rates seen in this negative study. Further regimens should be explored to improve the OS of these patients with poor prognosis.

RESUMO

The case of a 54-year-old woman is presented. She underwent right sided unilateral nephrectomy for metastatic bilateral renal tumour of the Bellini collecting ducts. Progression of the contralateral tumour resulted in acute complete anuric renal failure. Haemodialysis was started along with palliative gemcitabine (1000 mg/m(2))-cisplatine (70 mg/m(2)) chemotherapy. In parallel, renal function was improving and dialysis could be stopped at the end of the chemotherapy line comprising 6 cycles. Half a year later the patient was lost of uncontrolled local and pulmonary progression. The potentially nephrotoxic cisplatine chemotherapy associated to complex supportive treatment improved the renal function by controlling diffusely infiltrative tumour growth and allowed a survival benefit over one year with active household keeping capacity.

RESUMO

BACKGROUND: Early risk-stratified chemotherapy is a standard treatment for breast, colorectal, and lung cancers, but not for high-risk localised prostate cancer. Combined docetaxel and estramustine improves survival in patients with castration-resistant prostate cancer. We assessed the effects of combined docetaxel and estramustine on relapse in patients with high-risk localised prostate cancer. METHODS: We did this randomised phase 3 trial at 26 hospitals in France. We enrolled patients with treatment-naive prostate cancer and at least one risk factor (ie, stage T3-T4 disease, Gleason score of ≥8, prostate-specific antigen concentration >20 ng/mL, or pathological node-positive). All patients underwent a staging pelvic lymph node dissection. Patients were randomly assigned (1:1) to either androgen deprivation therapy (ADT; goserelin 10·8 mg every 3 months for 3 years) plus four cycles of docetaxel on day 2 at a dose of 70 mg/m(2) and estramustine 10 mg/kg per day on days 1-5, every 3 weeks, or ADT only. The randomisation was done centrally by computer, stratified by risk factor. Local treatment was administered at 3 months. Neither patients nor investigators were masked to treatment allocation. The primary endpoint was relapse-free survival in the intention-to-treat population. Follow-up for other endpoints is ongoing. This study is registered with ClinicalTrials.gov, number NCT00055731. FINDINGS: We randomly assigned 207 patients to the ADT plus docetaxel and estramustine group and 206 to the ADT only group. Median follow-up was 8·8 years (IQR 8·1-9·7). 88 (43%) of 207 patients in the ADT plus docetaxel and estramustine group had an event (relapse or death) versus 111 (54%) of 206 in the ADT only group. 8-year relapse-free survival was 62% (95% CI 55-69) in the ADT plus docetaxel and estramustine group versus 50% (44-57) in the ADT only group (adjusted hazard ratio [HR] 0·71, 95% CI 0·54-0·94, p=0·017). Of patients who were treated with radiotherapy and had data available, 31 (21%) of 151 in the ADT plus docetaxel and estramustine group versus 26 (18%) of 143 in the ADT only group reported a grade 2 or higher long-term side-effect (p=0·61). We recorded no excess second cancers (26 [13%] of 207 vs 22 [11%] of 206; p=0·57), and there were no treatment-related deaths. INTERPRETATION: Docetaxel-based chemotherapy improves relapse-free survival in patients with high-risk localised prostate cancer. Longer follow-up is needed to assess whether this benefit translates into improved metastasis-free survival and overall survival.

RESUMO

BACKGROUND: This study aims to better define prognostic factors for patients with metastatic urothelial carcinoma (mUC), and to identify patients who will benefit from first-line cisplatin-based chemotherapy. We test the hypothesis that early objective response (EOR), defined as the occurrence of an objective response following 2 or 3 courses of chemotherapy, could be a prognostic factor for overall survival (OS) and thus be used to guide treatment decisions. Data from 113 patients with evaluable mUC receiving first-line cisplatin-based treatment between January 2004 and December 2006 was collected retrospectively from prospectively-maintained databases across seven French cancer centers. Clinical factors potentially associated with survival and EOR were analyzed in univariate and multivariate analysis. RESULTS: One hundred three patient records were complete and available for inclusion in the multivariate model. Four factors were independently associated with OS: Performance status 1 and 2 (HR 2.3 [95 % CI 1.3-3.9], p = 0.002; HR 3.4 [95 % CI 1.6-7.2], p = 0.001 respectively); presence of visceral metastases (HR 2.2 [95 % CI 1.3-3.9], p = 0.004); abnormal hemoglobin levels (HR 1.7 [95 % CI 1.01-2.8], p = 0.045); disease progression (HR 10.1 [95 % CI 4.2-24.1], p < 0.001). CONCLUSIONS: This study confirms the prognostic factors previously reported in first-line chemotherapy for mUC. However, we failed to demonstrate that EOR was an independent predictive factor of OS. Nevertheless, an early response evaluation is recommended since early progression is an important parameter that can be used to decide whether treatment should be interrupted and changed for alternative strategies integrating the concept of personalized medicine or new immune therapies.
