RESUMO

AIM: To analyze the indications of radical prostatectomy and lymph node dissection retained during the last 12 years in an academic surgical center in the Paris region in order to ensure their adequacy in relation to the current clinical guidelines. METHOD: Monocentric retrospective study of prospectively collected data, between 2007 and 2019. Analysis of the clinical and pathological characteristics which were taken into account during multidisciplinary meeting discussion for the treatment decision, and comparison of their evolution over the four 3-year period corresponding to the clinical guideline updates. RESULTS: Two thousand eighty-eight consecutive patients treated by radical prostatectomy between 16/03/2007 and 17/03/2019 were included. The proportion of patients classified as low, intermediate or high risk according to D'Amico system was 13.2%, 80.8% and 6.0% respectively. An increase in the frequency of surgical treatment of high-risk cancers has been observed. At the same time, there has been a decrease in the frequency of prostatectomies to treat low-risk cancers. CONCLUSION: The indications for radical prostatectomy and lymph node dissection have evolved in line with the current clinical guidelines which were taken into consideration in a onco-urological multidisciplinary meeting. LEVEL OF EVIDENCE: 3.

RESUMO

INTRODUCTION: The influence of the delay between prostate biopsy and radical prostatectomy for patients with localized prostate cancer is controversial. The objective of this study was to establish a time limit between prostate biopsy and radical prostatectomy beyond which the risks of upgradging and biochemical recurrence (BCR) are increased. MATERIAL AND METHODS: Between January 2013 and January 2017, a retrospective analysis of the clinical, biological and histological data of 513 patients treated with radical prostatectomy for localized prostate cancer was performed in a single center. The primary endpoint was the assessment of the risk of BCR by the difference between post-biopsy USCF-CAPRA and post-surgical CAPRA-S scores. The secondary endpoint was the evaluation of the upgrading by the difference between the Gleason score on biopsy and on surgical specimen. The risks of BCR and upgrading were compared by Student test according to different delays between prostate biopsy and radical prostatectomy. The shortest delays for which a significant difference was found were reported. RESULTS: In this study, 513 patients were included. The median age at the time of the biopsy was 65 years (IQR: 60-69). The median preoperative PSA was 7.30ng/mL (IQR: 5.60-9.94). The median time between biopsy and surgery was 108 days (IQR: 86-141). For the entire cohort, the risk of BCR was significantly higher above a threshold of 90 days (P=0.039). No threshold was found for Gleason 6(3+3) patients. A 90-day threshold was found for Gleason 7(3+4) patients (P=0.038). Gleason patients≥8 had more upgrading beyond a 60-day threshold (P=0.040). CONCLUSION: Our study showed that after a 3 months delay, the risk of BCR was significantly higher for localized prostate cancer. It seemed possible to extend this period for low-risk patients, whereas it seemed necessary to keep it for intermediate-risks and to reduce it to 2 months for high-risks. LEVEL OF EVIDENCE: 4.

RESUMO

BACKGROUND: To compare histological feature of prostate cancer (PCa) according androgenic status in patients who underwent radical prostatectomy (RP). METHODS: Between March 2007 and September 2013, we prospectively analysed 937 patients who were referred to our centre for RP. Clinical, pathological and biological data have been prospectively collected. Preoperative total testosterone (TT) and bioavailable testosterone (BT) serum determinations were carried out. The threshold for low serum testosterone was set at TT<3 ng/ml. Preoperative PSA value was registered. Gleason score (GS) and predominant Gleason pattern were determined in prostate biopsies and in prostate tissue specimens, crosschecked by two uro-pathologists. RESULTS: Nine hundred and thirty-seven consecutive patients were included. In all, 14.9% patients had low TT in the population. An exact match between biopsy and prostate specimens in GS grading was observed for 50.6% patients (n=474). Also, 40.9% of all patients were upgraded (n=383): 45.3% (n=63) in low serum testosterone patients and 40.1% (n=320) in normal serum testosterone patients. For prostate specimens, the proportion of patients with predominant Gleason pattern 4 was higher in patients with low TT compared with normal TT (41.7% vs 29.1%, P=0.0029). In all, 20.1% were upgraded from predominant Gleason pattern 3 on biopsies specimen to predominant Gleason 4 pattern on the prostate specimen in patients with low TT, whereas 11.6% were upgraded for normal TT patients (P=0.002). CONCLUSIONS: Low serum testosterone is an independent risk factor for predominant Gleason pattern 4 on prostate specimen after RP and for upgrading from low- to high-grade cancer between prostate needle biopsies and RP specimen. This observation should be taken into account in localised PCa management, especially for active surveillance or when a nerve-sparing approach is considered.

RESUMO

BACKGROUND: The detection of lymph node metastases in bladder cancer has a major impact on treatment decisions and patients prognosis. Due to limited value of conventional imaging, the place of molecular and functional imaging needs to be precised, particularly in the neoadjuvant setting. METHODS: From June 2011 to June 2013, 102 patients with clinically localized BCa were simultaneously staged with (18)F-FDG PET/CT before RC. This study assessed the diagnostic accuracy of (18)F-FDG PET/CT for the detection of metastases in normal-sized lymph nodes using extended pelvic lymph node dissection and histopathology as the reference standard. RESULTS: A total of 1211 LNs were examined histopathologically. Sixty-seven (5.5%) metastatic nodes were found in 26/102 patients (25.5%). Lymph node density was 22%. On patient-based analysis, sensitivity, specificity, predictive positive value (PPV), negative positive value (NPV) and accuracy for (18)F-FDG PET/CT were calculated as 50%, 96.2%, 80%, 86.2% and 85.3% respectively. On a field-based analysis, sensitivity, specificity, PPV, NPV and accuracy for (18)F-FDG PET/CT were calculated as 50.0%, 99.0%, 71.9%, 97.4%, and 96.5% respectively. The majority of missed metastases were micrometastasis <5 mm in long axis diameter. CONCLUSIONS: (18)F-FDG PET/CT improves diagnostic efficacy for lymph node staging in patients staged N0 with conventional cross-sectional imaging. (18)F-FDG PET/CT could be used as a surrogate marker for detection of metastases in non-enlarged pelvic lymph nodes and enhances management strategy guiding patients selection for neoadjuvant chemotherapy.

RESUMO

OBJECTIVE: Study and evaluate the orthotopic Z-shaped neobladder in the long term and life quality of patients bearing this type of replacement. METHODS: Based on 162 medical records of patients who have undergone total cystoprostatectomy and orthotopic Z-shaped replacement because of bladder cancer with a minimal 5-year follow-up. Forty patients (113-month average follow-up) residing in the region were notified for a clinical consultation and were the basis for the target population of this study. A physical examination, a Pad test and a specific consultation allowed for continence evaluation whereas three validated surveys allowed for life quality appreciation. RESULTS: Continence was satisfactory for 82% of the patients during the day and 55% during the night. There was a significant negative correlation between a patient's age at the time of the cystoprostatectomy and diurnal continence. Life quality was estimated as good in the long term. CONCLUSION: The functional results of the Z-shaped ileal detubulated neobladder in the long term are satisfactory. It allows for good urination quality and satisfactory quality of life for patients subject to total cystoprostatectomy because of cancer as well as body schema's conservation.

RESUMO

OBJECTIVE: To evaluate the impact of imperative indication on the rate of complications and long term carcinological results after partial nephrectomy (PN). PATIENTS AND METHOD: Between 1985 and 2005, all patients who had a PN for localized cancer in two centers were reviewed. The rates of global, hemorrhagic and urinary complications were compared between group I (elective indication) and group II (imperative indication). Rates of survival without recurrence and specific at 5, 10 and 20 years were compared between these two groups. A multivariate analysis using the Cox model was carried out to research factors associated with recurrence and death on the whole of the series. RESULTS: Three hundred and five patients were included in the study. No significant difference was found between group I and group II as far as global complications were concerned (17 vs 20%), the rate of hemorrhagic complications (3.5 vs 3.8%) and the rate of urinary complications (3.9 vs 2.5%). The patients who had been operated on for an imperative indication had survived specifically and without recurrence which was significantly lower at 5, 10 and 20 years. On the whole of the series, the imperative indication was the only independent factor associated with recurrence and death in a multivariate analysis. CONCLUSIONS: Even if the rate of complication does not appear to be significantly associated with the indication for operating, patients of imperative indication represented a heterogeneous group with a poorer prognosis. This factor should be taken into account in studies on the subject of PN.

RESUMO

INTRODUCTION AND OBJECTIVES: The aim of this study was to evaluate preliminary results of tension-free vaginal tape (TVT), a new surgical procedure, performed during the learning phase for the treatment of stress urinary incontinence. MATERIAL AND METHODS: One-hundred consecutive patients underwent surgery, between June 1998 and December 1999, by six different senior surgeons. Indications were socially annoying urinary stress incontinence which persisted after complete physical therapy education. Preoperative examination included a urodynamic evaluation program. Surgical procedure was performed according to Ulmsten technique under local, regional or general anaesthesia. Results were evaluated by self-evaluation questionnaire and the patients were followed for at least 1 year. RESULTS: Perioperative complications were: 14 bladder injuries and one urethral perforation without sequelae (except prolonged bladder drainage up to 3 days). Postoperative complications were: 13 retentions including 3 persistent after 1 month. During the learning phase (50 first patients) bladder injuries, retention and dysuria were more frequent. Progressively, local anesthesia was abandoned while most of the 50 remaining patients had TVT performed under epidural anesthesia. Functional results were divided into 3 groups according to preoperative urethral closure pressure (UCP) and eventual concomitant prolapse repair (PR): (1) UCP >25 cm H2O no PR (59 patients): 39 were totally dry without any instability, 13 dry with de novo (4) or persistent (7) instability and 5 were moderately improved. (2) UCP <25 cm H2O no PR (25 patients): 11 were dry without instability, 5 dry with instability, 6 were improved and 4 failed. (3) PR (15 patients): 9 were dry, 4 were improved and 2 failed. For 2 patients a bladder erosion due to the tape occurred (7 and 11 months) after the TVT procedure. CONCLUSIONS: During the learning phase, bladder perforation (22%) and retention (20%) were much more frequent than previously reported. Nevertheless, our results confirm that TVT appears to be an efficient procedure: 97% of patients were cured or improved when UCP >25 cm H2O, 85% when UCP <25 cm H2O and 87% when a PR was associated.

RESUMO

PURPOSE: To assess the efficacy and the safety of a new transurethral endoscopic device using bipolar electrocautery, the Gyrus system. This system permits rapid prostate tissue removal by endoscopic vaporization with little bleeding and no pad return using saline irrigation and therefore eliminating TURP syndrome. PATIENTS AND METHODS: Forty-two patients (mean age 70; range 49-90 years) with symptomatic benign prostatic hyperplasia (BPH) without suspected cancer, confirmed by digital rectal examination and PSA tests, were treated between October 1998 and February 1999 with the Gyrus and evaluated at 1 and 3 months postoperatively by the International Prostate Symptom Score (IPSS) and maximum urinary flow rate. RESULTS: No postoperative bleeding necessitating catheterization for postoperative retention occurred. The duration of the procedure was < or = 30 minutes in 12 patients, 30 to 60 minutes in 27 patients, and >60 minutes in 3 patients. The mean time of postoperative continuous bladder irrigation was 1.2 days (0.5-3 days). The mean catheterization time was 1.4 days (range 0.5-5 days). Urethral stricture requiring treatment occurred in two patients. Dysuria was reported by four patients (mild two, severe two). The postoperative hospitalization was a mean of 2.2 days. The mean peak flow rate increased from 7.9 to 19.7 mL/sec at 3 months, and the IPSS decreased from 16 to 9 at 3 months. CONCLUSION: Our preliminary results with a bipolar electrode for electrovaporization of the prostate using the Gyrus suggest that it is a useful and safe endoscopic device. It appears to be an effective treatment for BPH; however, long-term results (i.e., 1-year follow-up) should be evaluated. This pilot series permits a comparative study with TURP to assess the benefits for patients and the health care system.

RESUMO

OBJECTIVES: Cystectomy is the reference treatment for invasive bladder cancer and superficial tumours with a high risk of recurrence. However, the long-term results of this treatment remain controversial. Progress in anaesthesia-intensive care and surgical techniques appear to have improved the prognosis of this disease over the last two decades. The availability of numerous adjuvant therapies (radiotherapy and chemotherapy) and the development of alternative conservative management therefore require a re-evaluation of the long-term results of cystectomy for bladder cancer performed over the last 20 years. MATERIAL AND METHODS: The case files of 504 consecutive patients undergoing cystectomy for bladder cancer in our department from 1981 to 1997 were reviewed. The operative and postoperative morbidity and actuarial survival by stage were studied. Histological prognostic factors and the influence of adjuvant therapies were also studied. RESULTS: According to the TNM 97 classification, 55% of tumours (on the cystectomy specimen) were intravesical (< T3), and 70% of patients had negative lymph nodes (N0). The perioperative mortality was 1.56%. The overall survival at 2 years, 5 years and 10 years for the total patient population was 83.1%, 52.3% and 46.6%, respectively. The 5-year survival of tumours confined to the bladder (< T3) was 79.4% versus 27.5% when the tumour extended beyond the bladder (> T3). The lymph node status considerably influenced survival. N0, N1 and N2-3 patients had 5-year survival rates of 64%, 48% and 14%, respectively. Neoadjuvant chemotherapy or radiotherapy did not appear to improve survival. CONCLUSIONS: Survival after cystectomy for bladder cancer essentially depends on pathological stage and lymph node status. Patients with a localized tumour have a 5-year survival greater than 80%. Prospective studies are required to determine the real benefit of adjuvant chemotherapy, as its value has not yet been formally demonstrated.

RESUMO

PURPOSE: Proliferation rate is an important determinant of bladder tumor progression. However, this factor has not yet been correlated to bacillus Calmette-Guérin (BCG) therapy response in a selected high-risk population of patients with stage T1 grade G3 bladder cancer. To assess the predictive value of the proliferation rate, an immunoreactivity test with monoclonal antibodies MIB-1 was carried out. The aim of this study was to evaluate the prognostic value of an MIB-1 labeling index by selecting a group of responsive patients prior to intravesical therapy. MATERIALS AND METHODS: After complete transurethral resection, 35 patients with T1G3 bladder carcinoma received 6 weekly installations of BCG (intravesical Pasteur strain: 75 mg in 50 ml course of BCG therapy). After treatment a cystoscopy and randomized biopsies of the bladder mucosa were carried out and all recurrences were systematically resected. All tissue samples were fixed in Bouin's solution, embedded in paraffin and stained with hematoxylin-eosin-safran. Pathologists had sufficient material to perform immunomarking in 25 patients using peroxidase-antiperoxidase (PAP) technique, with antiprotein monoclonal antibody MIB-1 (Immunotech, Marseilles, France) to study MIB-1 expression before BCG therapy. Consensus was obtained from three independent pathologists for all sections. The results were expressed in a percentage of marked nuclei. Ten percent increment thresholds were established from 10 to 60%. Contingency tables were established, chi2 (p1) and Fisher exact test (p2) were performed for each threshold of 10%. RESULTS: Median follow-up was 57.3 months (range 25-144). Of the 25 patients, 8 (32%) did not respond to BCG therapy, 17 (68%) responded positively. With a 20% threshold, there was a statistical difference (p1 = 0.03, p2 = 0.04) between responder (R) and nonresponder (NR) patients. All the 7 patients with less than 20% of nuclear activity positively responded to BCG. At this threshold level, sensitivity was high but specificity low (positive predictive value = 0.44). If we consider other reactivity thresholds there were no statistical differences between R and NR patients (10%) threshold p1 = 0.13, p2 = 0.19; 30% p1 and p2 = 0.20; 40% p1 = 0.82, p2 = 0.61; 50% p1 = 0.57, p2 = 0.55). CONCLUSION: Our study indicates that the proliferation rate, assessed by MIB-1 immunoreactivity in Bouin's solution-fixed primary tissue, could be a useful predictive marker of outcome in T1G3 bladder carcinoma. With a 20% reactivity cut-off, a negative MIB-1 immunomarking appears to predict a positive response to BCG instillations. However, on the other hand, MIB-1 is of limited clinical use because the low specificity of this test cannot predict failure and then select candidates for cystectomies.

RESUMO

OBJECTIVE: The treatment of La Peyronie disease is still controversial. ESWL has been recently proposed to treat symptomatic plaques. The results, although discordant and often based on subjective assessment criteria, appear to show a certain degree of efficacy on so-called young plaques, i.e. during the acute phase of the disease. This study was designed to evaluate the results obtained with a classical lithotriptor (Siemens Multiline) on plaques present for less than 6 months. MATERIAL AND METHOD: 26 patients were included in this prospective study. All presented a painful plaque on erection. The plaque was palpated under general anaesthesia and 0.5 to 2 ml of contrast agent were injected to allow radiological visualization. All patients received 3000 impacts at a power of 7 kilojoules in 1 session and all were reviewed 1 month and 3 months after the ESWL session. RESULTS: Treatment was perfectly tolerated. Among the 26 patients treated: 19 patients (73%) reported a very marked reduction of pain on erection and 8 (31%) reported a reduction of curvature on erection, but this reduction was demonstrated objectively (by tracing or photographs) for only 3 patients (11%). Seven patients (27%) experienced softening of the plaque. Six (37%) of the patients suffering from erectile dysfunction reported improvement of the quality of erection, as reflected by the HEF score. CONCLUSION: A standard lithotriptor can be used to treat La Peyronie plaques. ESWL appears to have a marked analgesic effect, but its efficacy on correction of curvature of the penis was not demonstrated in this study.

RESUMO

PURPOSE: Bacillus Calmette-Guerin (BCG) therapy is considered to be an effective prophylactic and therapeutic agent for high risk superficial transitional cell carcinoma of the bladder. Nevertheless, in a select uncommon population of stage Ta grade 3 superficial lamina-free tumors the results of this treatment have not yet been well established. We evaluated recurrence and progression rates, and the success of BCG therapy in a population with stage Ta grade 3 transitional cell carcinoma of the bladder. MATERIALS AND METHODS: Of the 605 patients treated at our institution from 1982 to 1996 for the histopathological diagnosis of primary bladder cancer 32 (5.3%) with stage Ta grade 3 noninvasive primary bladder tumor were treated with intravesical instillations of 75 mg. Pasteur strain BCG in 50 ml. saline weekly for 6 weeks. At a followup of 2 to 13 years (mean 58.4 months) patients were evaluated with urinary cytology, cystoscopy, transurethral resection and random mucosal biopsies. Recurrence, grade and stage progression, death and causality were analyzed. RESULTS: Of the 32 patients 9 (28%) responded positively to BCG without recurrence, while disease recurred as stage Ta in 8 (25%) and T1 in 7 (22%), and progressed to muscle layer infiltration in 8 (25%). Four patients (12%) died of bladder cancer. The number of tumors at primary resection, gross examination, the mitotic index or an association with carcinoma in situ did not appear to be predictive factors of progression to muscle invasion. Urine cytology (I to II versus III to IV) appeared to correlate highly with progression and BCG response (p<0.001) with excellent sensitivity (1) but low specificity (0.67). CONCLUSIONS: Our study demonstrates the high progression potential of stage Ta grade 3 tumors, since nearly 50% recurred and 25% progressed to invasive disease. These results may be closely compared with the results of previous trials of stage T1 grade 3 disease. We suggest that recurrence should be detected at an early stage using long-term followup with strict observance of the surveillance protocols during a minimum 5-year tumor-free period.

RESUMO

OBJECTIVES: The objective of this study was to compare the proliferation index (immunolabelling by monoclonal antibody Ki67 - MIB-1) of renal cell carcinomas as a function of the presence or absence of renal vein thrombus. Analysis of the numbers of Ki67-positive nuclei can be used to assess the degree of aggressiveness of the cell populations of these various carcinomas (tumour without thrombus, tumour with thrombus and neoplastic thrombus). METHODS: Twenty three renal cell carcinomas with renal vein thrombus were matched for Furhman grade (1st degree), tumour volume (2nd degree) and the patient's age (3rd degree) with 23 renal cell carcinomas not presenting any vascular embolus on histology. Monoclonal antibody MIB-1 immunolabelling was performed on 69 paraffin-embedded specimens: 23 tumours with thrombosis, the 23 corresponding neoplastic thrombi and 23 tumours without vascular embolus. RESULTS: A correlation between Furhman grade and the percentage of immunolabelled nuclei was observed (mean: 2.67% for low-grade tumours and 14.34% for high-grade tumours). No labelling difference was observed between the two populations of primary tumours (with thrombus/without embolus). Primary tumours presented significantly weaker Ki67 labelling than their corresponding neoplastic thrombus (mean of 2.47% versus 10.3%, p < 0.01). CONCLUSION: This study shows that there is no difference of the proliferation index between tumours with neoplastic venous thrombus and those with no histological vascular embolus. However, a difference of proliferation index was observed between the primary tumour and its corresponding thrombus, which presented a statistically higher immunolabelling. This finding suggests that the thrombus possesses more dividing cells than the primary tumour, i.e. has a shorter doubling time.

RESUMO

OBJECTIVES: Vasoactive drugs used for self-administered intracavernous injections are currently the reference treatments for erectile dysfunction after radical prostatectomy. The acceptability of and compliance with this treatment often limit their use. This study analysed these two parameters as a function of the type of andrological management decided before radical prostatectomy. MATERIAL AND METHOD: From January 1996 to January 1997, 45 sexually active patients, aged 52 to 69 years, requiring radical prostatectomy without preservation of the nervi erigentes, for localized prostate cancer, were included in this prospective study. Before the operation all 45 patients were informed about the high risk of erectile dysfunction following radical prostatectomy. Fifteen patients (group 1) did not receive any particular advice concerning the management of erectile dysfunction after radical prostatectomy, but were possibly referred for an andrology consultation depending on their complaints. Fifteen patients (group 2) were systematically referred for an andrology consultation three months after radical prostatectomy for information about the available treatment options. For 15 patients (group 3), the andrology consultation (3 months after the operation) had been planned before radical prostatectomy to perform a test injection of prostaglandin E1. The injections, started before the operation in this group 3, therefore constituted an integral part of the global management of prostate cancer. All these patients were followed for at least 1 year in the urology department. RESULTS: Only 7 of the 15 patients of group 1 consulted an andrologist. Five of these patients received a test intracavernous injection versus 14 in group 2 and 15 in group 3. The 5 patients of group 1 who received an intracavernous injection accepted this modality as treatment versus 8 in group 2 and 12 in group 3. After one year, 4, 5 and 9 patients in groups 1, 2 and 3, respectively, continued intracavernous injections. CONCLUSION: The management of erectile dysfunction after radical prostatectomy must start with the decision to operate. Systematic encouragement to use intracavernous injections after radical prostatectomy helps to improve access to this treatment for impotence. The acceptability, and especially the compliance, appear to be better in patients in whom intracavernous injections were integrated into the global management of their prostate cancer.

RESUMO

A ureteric tumour was discovered in a patient presenting with an episode of renal colic and a history of prostatectomy for prostatic adenocarcinoma. Segmental ureterectomy was performed. Histological examination showed a metastasis from prostatic adenocarcinoma. This is a rare site of secondaries: less than 40 cases have been reported in the literature, essentially based on autopsy series. Metastatic spread occurs via lymphatics or the blood stream, and the secondary tumour develops from the adventitia before invading the ureteric wall. Although this diagnosis may be suggested by the clinical features and imaging, it can only be confirmed by histology. After ureterectomy, treatment can combine all of the recognized treatment modalities against prostatic adenocarcinoma: endocrine therapy and adjuvant radiotherapy.

RESUMO

The aim of this retrospective study was to evaluate the effects and results of low-dose bacillus Calmette-Guérin (BCG) therapy on a selective high-risk population of stage T1, grade 3 (G3) bladder tumours. Recurrence and progression were also analysed. Thirty-five consecutive patients presenting with T1 G3 tumours were treated with intravesical BCG. All patients underwent complete transurethral tumour resection. A course of BCG 75 mg Pasteur strain was begun 4 weeks after the first resection of the diagnosed tumour and continued for a 6-week period. At the end of treatment, a complete urological evaluation was routinely carried out: urine cytology test, cystoscopy with bladder biopsies randomly performed, and any recurrences were resected. In cases of abnormal cytology and/or recurrence an additional course of BCG was initiated, followed by the same tests. Follow-up examination and cystoscopy or fibroscopy were conducted every 3 months for 1 year, semiannually and annually thereafter. Median follow-up was 45 months (range 10-120); 7 patients (20%) did not respond to BCG instillations. Of these patients, 5 underwent cystectomy and in 2 patients the bladder was left in place in spite of recurrence because of age (+80 years). Twenty-eight patients (80%) responded positively, 24 after one single course of BCG, and 4 patients after two courses. During follow-up, recurrence was observed in 8 cases: stage T1 G3 in 4 patients, T1 CIS (carcinoma in situ) in 2 patients, Ta G2 and Ta G1 in 2 patients. Three of these patients were treated by cystectomy and the remaining patients with transurethral resection alone or combined with additional courses of BCG. Overall, 25 patients (71%) were considered free of tumour occurrence after low-dose BCG therapy. Ten patients underwent cystectomy (29%) or remained in occurrence and 2 patients died of the disease. These results can be closely compared to the results of other trials conducted on stage T1 G3 and BCG treatment, using a different dosage and BCG protocol therapy. BCG is an effective prophylactic and therapeutic agent for T1 G3 carcinoma of the bladder responders. The identification of these responders before beginning instillations still remains a challenge.

RESUMO

OBJECTIVE: The management of the male urethra after cystectomy for bladder cancer continues to be a dilemma. Patients who undergo a cystectomy require either urinary diversion or bladder substitution. Therefore, the use of the urethra to ensure voiding is important. On the other hand, the probable risk of urethral carcinoma recurrence is generally estimated at approximately 10%. The aim of this study was to assess the predictive value of preoperative urethral biopsies, and of frozen sections during cystoprostatectomy, in patients with invasive bladder cancer. METHODS: From 1982 to 1986, 118 male patients underwent a cystoprostatectomy for transitional cell carcinoma of the bladder. All patients underwent endoscopic latero-montanal biopsies 2 weeks preoperatively and urethral frozen cut section during radical prostatocystectomy. RESULTS: Carcinoma was observed in 12 patients on both examinations. All patients underwent en bloc urethrectomy during cystectomy. In the remaining 106 patients, the frozen cut margin was negative (including 9 with positive latero-montanal biopsies), and these patients had the urethra preserved. After a 10-year minimum follow-up, no recurrence was observed in these patients with negative frozen cut-section. No significant risk factors for urethral recurrence were found. Latero-montanal biopsies did not reveal a positive specificity, and this procedure was later abandoned in our institution (in 1986). CONCLUSIONS: The urethral frozen section was the only guideline used for simultaneously performing the urethrectomy. All male patients with negative frozen cut sections should be considered candidates for bladder substitution. A prophylactic urethrectomy is only indicated in patients with carcinoma (minimum carcinoma in situ) in the frozen urethral margin section during cystectomy.
