RESUMEN

INTRODUCTION: Serum prostate specific antigen (PSA) is a well-known prognostic parameter in men with prostate cancer. The treatment of men with very high PSA values and apparently no detectable metastases is not fully established. PATIENTS AND METHODS: Ancillary analysis from the GETUG 12 phase 3 trial. Patients with non-metastatic high-risk prostate cancer by bone and computerized tomography (CT) scan were randomly assigned to receive androgen deprivation therapy (ADT) and docetaxel plus estramustine or ADT alone. Relapse-free survival (RFS), clinical RFS, metastases-free survival (MFS), overall survival (OS), and prostate cancer-specific survival (PCSS) were estimated using the Kaplan-Meier method for different levels of PSA (50 ng/mL, 75 ng/mL, and 100 ng/mL). The relationship between PSA and outcomes was studied using residual-based approaches and spline functions. RESULTS: The median follow-up was 12 years (range: 0-15.3). Baseline PSA (<50 ng/mL, n = 328; ≥50ng/mL, n = 85) was associated with improved RFS (P = .0005), cRFS (P = .0024), and MFS (P = .0068). The 12-year RFS rate was 46.33% (CI 40.59-51.86), 33.59% (CI 22.55-44.97), and 11.76% (1.96-31.20) in men with PSA values <50 ng/mL (n = 328), 50-100 ng/mL (n = 68), and ≥100 ng/mL (n = 17), respectively. Exploratory analyses revealed no deviation from the linear relationship assumption between PSA and the log hazard of events. CONCLUSIONS: Men with apparently localized prostate cancer and a high baseline PSA value have a reasonable chance of being long-term disease-free when treated with curative intent combining systemic and local therapy.

RESUMEN

PURPOSE: The role of pelvic elective nodal irradiation (ENI) in the management of prostate cancer is controversial. This study analyzed the role of pelvic radiation therapy (RT) on the outcome in high-risk localized prostate cancer patients included in the Groupe d'Etude des Tumeurs Uro-Genitales (GETUG) 12 trial. METHODS AND MATERIALS: Patients with a nonpretreated high-risk localized prostate cancer and a staging lymphadenectomy were randomly assigned to receive either goserelin every 3 months for 3 years and 4 cycles of docetaxel plus estramustine or goserelin alone. Local therapy was administered 3 months after the start of systemic treatment. Performance of pelvic ENI was left to the treating physician. Only patients treated with primary RT were included in this analysis. The primary endpoint was biochemical progression-free survival (bPFS). RESULTS: A total of 413 patients treated from 2002 to 2006 were included, of whom 358 were treated using primary RT. A total of 208 patients received pelvic RT and 150 prostate-only RT. Prostate-specific antigen (PSA) concentration, Gleason score, or T stage did not differ according to performance of pelvic RT; pN+ patients more frequently received pelvic RT than pN0 patients (P<.0001). Median follow-up was 8.8 years. In multivariate analysis, bPFS was negatively impacted by pN stage (hazard ratio [HR]: 2.52 [95% confidence interval [CI]: 1.78-3.54], P<.0001), Gleason score 8 or higher (HR: 1.41 [95% CI: 1.03-1.93], P=.033) and PSA higher than 20 ng/mL (HR: 1.41 [95% CI: 1.02-1.96], P=.038), and positively impacted by the use of chemotherapy (HR: 0.66 [95% CI: 0.48-0.9], P=.009). There was no association between bPFS and use of pelvic ENI in multivariate analysis (HR: 1.10 [95% CI: 0.78-1.55], P=.60), even when analysis was restricted to pN0 patients (HR: 0.88 [95% CI: 0.59-1.31], P=.53). Pelvic ENI was not associated with increased acute or late patient reported toxicity. CONCLUSIONS: This unplanned analysis of a randomized trial failed to demonstrate a benefit of pelvic ENI on bPFS in high-risk localized prostate cancer patients.

RESUMEN

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.

RESUMEN

OBJECTIVES: To define the profile of patients with prostate cancer (PCa) receiving a 3-month or 6-month formulation of luteinizing hormone-releasing hormone (LHRH) agonist in France and the reasons for choosing between formulations. METHODS: This prospective 1-year observational study included patients with PCa starting LHRH agonist therapy in everyday practice. Reasons for prescription and patient preference were recorded at inclusion, 3 or 6 months, and 12 months. The percentage of patients with a renewed initial prescription was recorded during follow up. RESULTS: A total of 1438 patients with PCa were included. Hormonotherapy was initiated more frequently with a 6-month (n = 903; 62.8%) than with a 3-month formulation (n = 535; 37.2%). The initial prescription was renewed in most patients after 3 or 6 months (86.1%) and 12 months (71%); 170 patients switched from a 3-month to a 6-month formulation during follow up. Presence of metastases influenced initial prescription (odds ratio 0.439; 95% confidence interval 1.095-1.892), with a 3-month formulation more often prescribed than a 6-month formulation to men with metastatic PCa at diagnosis (21.3% versus 15.8%, respectively). The most frequent reasons given by physicians for choosing the 6-month formulation were 'simplification of therapeutic regimen' (86.9%) or 'fewer unnecessary visits' (46.8%). Similar reasons were given for switching from a 3-month to a 6-month formulation during follow up. The most frequent reasons given by physicians to initiate therapy with a 3-month formulation were 'usual practice/habit' (55.5%) or 'closer patient management' (46.2%). 'Closer patient management' and 'reassuring effect upon patient' were the main reasons for switching from a 6-month to a 3-month formulation during follow up. Approximately 80% of patients were satisfied with the formulation they were prescribed and patients' reasons for preferring one formulation over another were similar to the physicians' reasons for prescribing these formulations. CONCLUSIONS: Slow-release formulations of LHRH agonists are useful therapies for physicians treating patients with PCa and there may be a preference for the 6-month formulation.

RESUMEN

This French observational, longitudinal, prospective study described the health-related quality of life (HRQoL) of elderly men (≥75 years old) with prostate cancer after initiating gonadotropin-releasing hormone (GnRH) agonist therapy. At baseline and 3-6 months after baseline, European Organisation for Research and Treatment of Cancer quality of life questionnaire-core 30 (QLQ-C30) and prostate-specific (QLQ-PR25) questionnaires were completed by patients. Data from 1276 patients were analyzed. At baseline, mean (±SD) age was 80 (±4.1) years, 29.1% of patients had Gleason scores ≥8 and 24.9% had metastases. At baseline, increasing age, presence of metastasis and presence of comorbidity had a negative impact on QLQ-C30 and QLQ-PR25 scores. At follow-up, improvement in emotional-functioning (2.8; p < 0.001), social-functioning (1.7; p = 0.011), global HRQoL (1.6; p = 0.029), sleep-disturbance (-2.1; p = 0.011), appetite-loss (-4.0; p < 0.001) and pain (-4.1; p < 0.001) QLQ-C30 scores were observed. In addition, there was a worsening in treatment-related symptom (8.6; p < 0.001), sexual-activity (-5.5; p < 0.001) and sexual-functioning (-22.6; p < 0.001) QLQ-PR25 scores, and an improvement in urinary symptoms (-3.7; p < 0.001) and incontinence aid (-2.9; p = 0.023) QLQ-PR25 scores. This study shows that, apart from the expected impact on sexual functioning domains, HRQoL is not adversely affected by 3-6 months of GnRH agonist therapy in older men with prostate cancer.

RESUMEN

After cystectomy, the urine is eliminated by the uretra (orthotopic neobladder) or through a stoma. Orthotopic neobladder is done by priority when feasible. Practical aspects have to be managed very strictly by the urologist and the staff nurse. Side effects and complications are quite frequent (incontinence, retention, infection, diminished renal function, metabolic disorders, stoma complications) and need an adapted follow-up to propose adapted management if necessary.

RESUMEN

BCG therapy, which is the standard treatment for non-muscle invasive bladder tumours with high risk of recurrence and progression, has potential life-threatening adverse effects (AEs). Rapid deterioration of general condition in a patient with history of bladder tumour should question about an ongoing treatment with BCG and specify the date of the last instillation. Trauma during catheterization and untreated concomitant urinary infection upon instillations are risk factors of severe AEs. In emergency, the diagnosis of severe AEs of BCG therapy is only based on the medical questioning with the notion of current BCG treatment and risk-bearing event upon instillation. Management of AEs is related to their pathophysiological mechanisms and relies on a combination of antibiotics against BCG, the symptomatic treatment, and corticosteroid therapy which has shown to improve patient outcomes.

RESUMEN

AIM: To assess docetaxel-estramustine in patients with localised high-risk prostate cancer. PATIENTS AND METHODS: After staging pelvic lymph node dissection, patients with high-risk prostate cancer randomly received androgen deprivation therapy (ADT) (3 years)+DE (4 cycles of docetaxel 70 mg/m(2)/3 weeks+estramustine 10mg/kg/dd1-5) or ADT alone. Local therapy was administered at 3 months. RESULTS: Four hundred and thirteen patients were accrued: T3-T4 (67%), Gleason score ~8 (42%), PSA >20 ng/mL (59%), pN+ (29%). In the chemotherapy arm, 94% of patients received the planned four cycles of docetaxel. Local treatment consisted of radiotherapy in 358 patients (87%) (median dose 74 Gy in both arms). ADT was given for 36 months in both arms. A PSA response (PSA ~0.2 ng/mL after 3 months of treatment) was obtained in 34% and 15% in the ADT+DE arm and in the ADT arm, respectively (p<0.0001). Febrile neutropenia occurred in only 2%. Moderate to severe hot flashes occurred less often in the ADT+DE arm (2% versus 22%; p<0.001). There was no toxicity-related death, no secondary leukaemia, and no excess second cancers. Chemotherapy had a negative impact on quality of life (global health status, p = 0.01; fatigue, p = 0.003; role functioning, p = 0.003; social functioning, p = 0.006) at 3 months but this effect disappeared at 1 year. CONCLUSION: Docetaxel-estramustine can be combined safely with standard therapy in high-risk prostate cancer, with a promising PSA response rate and no negative impact on quality of life after 1 year. Long-term follow-up is required to assess the impact on relapse and survival.

RESUMEN

Several types of gastrointestinal complications can occur during treatment with targeted therapies: diarrhoea, nausea and vomiting, abnormalities in hepatic and pancreatic profiles, etc. Gastrointestinal problems in targeted therapy can have a significant impact on the general status of patients, their weight and their adherence to the treatment. The prevention, screening and rapid treatment of these side-effects are essential elements of patient care and can limit the associated dose reductions and loss of therapeutic benefit. In the case of diarrhoea, treatment must be started at the onset of grade 1 or 2 diarrhoea (four to six stools per day), with loperamide or racecadotril. Treatment with targeted therapy must be stopped if there is diarrhoea of grade 3 or 4 (more than six stools per day). In the case of nausea/vomiting or burning pain in the oesophagus, symptomatic treatment without stopping the targeted therapy is recommended. Biological assessment including transaminases, total and conjugated bilirubin should be prescribed before treatment initiation with targeted therapy. An elevation in alkaline phosphatases without elevation of transaminases suggests primarily the existence of hepatic metastases. In the event of worsening of the hepatic profile, if ALT greater than 5N, treatment must be stopped and specialist advice sought.

RESUMEN

OBJECTIVE: To assess the oncological safety of laparoscopic procedures for the management of urothelial carcinomas of the urinary tract. METHODS: Data on laparoscopic management of urothelial carcinomas in the literature were analysed using MEDLINE and by matching the following keywords: urological malignancies, upper tract tumours, bladder carcinomas, laparoscopic approach, recurrence, follow-up and metastasis site. RESULTS: Minimally invasive techniques are being used increasingly in the management of these tumours and successfully achieving the benefits of lower blood loss and more rapid patient recovery. To date, no evidence level 1 information is available and published series of these technically challenging cases are small and follow-up limited. Short to medium term follow-up appears encouraging in terms of recurrence and survival rates, but long-term data are immature compared to the established open techniques these procedures seek to duplicate. Specific concerns in terms of the oncologic safety of laparoscopy, especially with regard to the pneumoperitoneum, tumour manipulation and specimen extraction are addressed. Port-site metastases and tumour seeding are rare events and appear to be mainly related to the grade and stage of the tumour. Specific precautions are required to minimise these risks. CONCLUSION: Oncological results of the laparoscopic approach are difficult to compare with those of open surgery. However, recent series have not reported unusual tumour dissemination or a higher rate of recurrence with this approach. Laparoscopic techniques are not yet standard of care in invasive urothelial carcinomas. Long-term assessment is ongoing and awaited.

RESUMEN

Prostate carcinoma is the most frequent cancer in French men. Prostate carcinoma in elderly is the topic of this review. The review included chapters on age as the main factor for prostate carcinoma, the modification of disease presentation or PSA level depending on age, and then the challenge of age in therapeutic decisions. Finally, we evaluate the place of elderly patients in prospective trials and in adjustable therapies.

RESUMEN

We discuss the efficacy and safety of high-intensity focused ultrasound (HIFU) in patients with prostate cancer, to define the best indications for HIFU in daily clinical practice as primary therapy. We searched Medline and Embase for clinical studies evaluating the efficacy and safety of HIFU in prostate cancer (July 2007), and abstracts presented at the 2005-2007 annual meetings of the European Association of Urology and American Urological Association were screened. In all, 37 articles/abstracts were selected. As the data on HIFU as salvage therapy were limited, we focused on HIFU as primary therapy. Studies consisted of case series only. Included patients were approximately 70 years old with T1-T2 N0M0 disease, Gleason Score or=70 years) with T1-T2 N0M0 disease, a Gleason score of <7, a PSA level of <15 ng/mL and a prostate volume of <40 mL. In these patients HIFU achieves short-term cancer control, as shown by a high percentage of negative biopsies and significantly reduced PSA levels. The median-term survival data also seem promising, but long-term follow-up studies are needed to further evaluate cancer-specific and overall survival rates before the indications for primary therapy can be expanded.
