Comparison of surgery alone with surgery and adjuvant radiotherapy for pT3N0 prostate cancer.

OBJECTIVE: To compare the outcome between patients with pT3N0 adenocarcinoma of the prostate treated with radical prostatectomy (RP) and those receiving RP followed by a planned course of postoperative radiation therapy (RT). PATIENTS AND METHODS: During a period of 22 years 622 patients with pT3N0 prostate cancer were treated in one medical centre by RP. Of these, 199 (32%) were treated with surgery alone while 423 (68%) received planned postoperative pelvic RT (median 48 Gy). Patients were selected for RT by having a higher incidence of adverse prognostic factors than those undergoing RP alone. These prognostic factors included pathological stage (P = 0.001) preoperative prostate specific antigen (PSA) level (P < 0.001) and Gleason score (P = 0.18). The patients' median age was 66 years; the median follow-up was 6.1 years for all patients, 7 years for RP + RT and 5 years for the RP-alone. RESULTS: The 5- and 10-year actuarial survival was 92% and 73%, respectively, for RP + RT patients, and nearly identical for those in the RP-alone group (P = 0.73). The 5- and 10-year disease-free survival (DFS; PSA < 0.05 ng/mL) was 69% and 51%, respectively, for the former, and 71% and 60%, respectively, for the latter group. There was no significant difference in DFS between the treatment groups by pathological stage and Gleason score (P = 0.77). Likewise, there was no significant difference in mean and median time to relapse. A preoperative PSA level of < 10 vs 10-25 vs > 25 ng/mL did not influence overall survival but a PSA of > 25 ng/mL was predictive of DFS (P = 0.02). In a multivariate analysis the Gleason score was the most important predictor for overall survival and DFS (P < 0.001), while pathological stage was predictive of clinical recurrence and DFS (P < 0.001). After controlling for pathological stage and Gleason score, RP + RT patients were predicted to recur at 92% of the rate of RP-alone patients (P = 0.65). In all, 43 (10%) patients developed a clinical recurrence in the RP + RT group, including 30 (7%) patients with distant metastases alone, 13 (3%) with local recurrence, with an additional 88 (21%) who had PSA recurrence (PSA > 0.05 ng/mL). This compared with 13 (6.5%) patients with clinical recurrence, including seven (3.5%) with local recurrence and 23 (11.6%) with PSA > 0.05 ng/mL in the RP-alone group. Postoperative RT was well tolerated and did not add to the incidence of surgical complications. CONCLUSION: We propose that postoperative RT, as described here, helped to reduce the incidence of local recurrence and improved DFS to equal that of a lower-risk group of patients treated with RP alone. A randomized comparison is needed to define the role of adjuvant RT in patients with pT3N0 disease.

T-mechanism applied to urinary diversion: the orthotopic T-pouch ileal neobladder and cutaneous double-T-pouch ileal reservoir.

PURPOSE: As the evolution of lower urinary tract reconstruction continues, newer and improved forms of urinary diversion have developed. Critical components of continent urinary reservoirs included an antireflux and continent mechanism that is effective, durable, easily constructed, and associated with little morbidity. MATERIALS AND METHODS: We describe the flap valve known as the T-mechanism as it applies to an afferent antireflux mechanism in an orthotopic ileal reservoir (T-pouch) and as an antireflux and efferent continence mechanism in the continent cutaneous ileal reservoir (double T-pouch). CONCLUSIONS: We believe the T-mechanism is an extremely effective and versatile flap-valve technique that can be easily learned and applied to the construction of continent urinary diversions.

Role of religion in the lives of Latino families of young children with developmental delays.

We interviewed 250 parents of Mexican and Puerto Rican origin living in the United States who had young children with developmental delays to determine the role of religion in their lives. Quantitative results indicate that parents largely viewed themselves as religious, were affiliated with a formal religion, and participated in religious activities. Most parents viewed both church and faith as supportive, but faith was shown to provide more support. Repeated measures a analysis of variance found some intragroup variations in religious support and changes in support after learning of the child's condition. Thematic analysis revealed specific religious beliefs and practices parents viewed as supportive, and content and cultural models analyses indicated the religious frameworks by which parents interpreted their child's disability.

Surgical approaches to venous tumor thrombus.

The extension of tumor thrombus into the vena cava by renal cell carcinoma remains a technically challenging surgical condition. Attention to surgical detail and perioperative care can provide long-term survival in the appropriately selected patient. In reviewing our experience of 99 patients with venous tumor extension: renal vein only (n = 31), infrahepatic vena cava (n = 22), intrahepatic vena cava (n = 34), and intra-atrial extension (n = 12), we have demonstrated overall 2- and 5-year survival rates of 54% and 33%, respectively. Level of tumor thrombus appears to be correlated with overall survival. We continue to advocate an aggressive, optimistic approach for those patients with clinically confined tumors with isolated venous tumor thrombus extension.

Radical cystectomy in the treatment of invasive bladder cancer: long-term results in 1,054 patients.

PURPOSE: To evaluate our long-term experience with patients treated uniformly with radical cystectomy and pelvic lymph node dissection for invasive bladder cancer and to describe the association of the primary bladder tumor stage and regional lymph node status with clinical outcomes. PATIENTS AND METHODS: All patients undergoing radical cystectomy with bilateral pelvic iliac lymphadenectomy, with the intent to cure, for transitional-cell carcinoma of the bladder between July 1971 and December 1997, with or without adjuvant radiation or chemotherapy, were evaluated. The clinical course, pathologic characteristics, and long-term clinical outcomes were evaluated in this group of patients. RESULTS: A total of 1,054 patients (843 men [80%] and 211 women) with a median age of 66 years (range, 22 to 93 years) were uniformly treated. Median follow-up was 10.2 years (range, 0 to 28 years). There were 27 (2.5%) perioperative deaths, with a total of 292 (28%) early complications. Overall recurrence-free survival at 5 and 10 years for the entire cohort was 68% and 66%, respectively. The 5- and 10-year recurrence-free survival for patients with organ-confined, lymph node-negative tumors was 92% and 86% for P0 disease, 91% and 89% for Pis, 79% and 74% for Pa, and 83% and 78% for P1 tumors, respectively. Patients with muscle invasive (P2 and P3a), lymph node-negative tumors had 89% and 87% and 78% and 76% 5- and 10-year recurrence-free survival, respectively. Patients with nonorgan-confined (P3b, P4), lymph node-negative tumors demonstrated a significantly higher probability of recurrence compared with those with organ-confined bladder cancers (P <.001). The 5- and 10-year recurrence-free survival for P3b tumors was 62% and 61%, and for P4 tumors was 50% and 45%, respectively. A total of 246 patients (24%) had lymph node tumor involvement. The 5- and 10-year recurrence-free survival for these patients was 35%, and 34%, respectively, which was significantly lower than for patients without lymph node involvement (P <.001). Patients could also be stratified by the number of lymph nodes involved and by the extent of the primary bladder tumor (p stage). Patients with fewer than five positive lymph nodes, and whose p stage was organ-confined had significantly improved survival rates. Bladder cancer recurred in 311 patients (30%). The median time to recurrence among those patients in whom the cancer recurred was 12 months (range, 0.04 to 11.1 years). In 234 patients (22%) there was a distant recurrence, and in 77 patients (7%) there was a local (pelvic) recurrence. CONCLUSION: These data from a large group of patients support the aggressive surgical management of invasive bladder cancer. Excellent long-term survival can be achieved with a low incidence of pelvic recurrence.

Nonrandomized comparison of surgery with and without adjuvant pelvic irradiation for patients with pT3N0 adenocarcinoma of the prostate.

The purpose of this study was to evaluate the outcome of radical prostatectomy alone and compare it with that of surgery followed by planned adjuvant radiotherapy in patients with pT3N0 prostate cancer (CaP). A total of 402 patients with CaP were treated with prostatectomy, including 311 (77%) who received a planned course of adjuvant radiotherapy (RT) (surgery [S] + RT) to the prostatic fossa (median dose: 48 Gy) and 91 (23%) who had surgery alone. Patients in the former group had worse risk factors than those in the latter group, such as a higher clinical and pathologic stage (p = 0.001), higher Gleason score (p = 0.09), and higher preoperative prostate-specific antigen (PSA) level (p = 0.0001). PSA failure was defined as more than 0.05 ng/ml. Median follow-up was 59 months. The 5- and 10-year overall survival for the 311 S+RT patients was 91% and 81%, respectively, and it was similar for those 91 in the surgery-alone group, p = 0.59. The 5- and 10-year probability of freedom from PSA and/or clinical failure for the former group was 70% and 53%, respectively, whereas it was 66% and 46%, respectively, for the latter group, p = 0.72. Any recurrence developed in a total of 96 (31%) patients in the S+RT group as compared with 23 (25%) in the surgery-alone group. Local recurrence was noted in 10 (3.2%) S+RT and in 6 (6.6%) surgery-alone patients (N.S.). The time to clinical or chemical recurrence was also similar for both treatment groups (median time: 3.0 versus 3.8 years). Patients with pT3b tumors had relatively poor 5- and 10-year disease-free survival (53% and 32%, respectively, for S+RT and 38% and 0%, respectively, for surgery alone, p = 0.82). In multivariate analyses, pathologic stage and Gleason score were independent predictors of recurrence, each with p < 0.001 after controlling for the other. The worst prognostic category included patients with pT3bN0, Gleason score 7-10 disease who had 5.0 times the risk of recurrence as compared with pT3aN0, Gleason score 2-6 patients. No significant difference in disease-free survival by the treatment group was seen in Cox regression analysis controlling for pathologic stage (p = 0.59), Gleason score (p = 0.99), and PSA (p = 0.28). S+RT patients were predicted to have disease recurrence at 83% the rate of surgery-alone patients, p = 0.42. Preoperative PSA (>25 ng/ml) was predictive of recurrence (2.0 x risk) in univariate analysis, but it was not a significant predictor in multivariate analysis. It appears that moderate-dose, localized fields postoperative irradiation reduced the incidence of local recurrence in patients who were at a higher risk of recurrence as compared with those treated with surgery alone. New treatment strategies need to be developed to manage pT3bN0, Gleason score 7-10 patients whose 10-year disease-free survival was poor.

Tube gastrostomy after radical cystectomy and urinary diversion: surgical technique and experience in 709 patients.

We describe our surgical technique of tube gastrostomy and report our experience with 709 patients who underwent cystectomy and urinary diversion with gastrostomy tube placement from January 1988 to December 1997. This modified Stamm technique provides an effective means of gastric decompression without the discomfort associated with nasogastric decompression, is associated with a low complication rate (0.05%), and may be considered as the procedure of choice when gastric drainage is required after radical cystectomy and lower urinary tract reconstruction.

Comparison of outcomes of radical prostatectomy with and without adjuvant pelvic irradiation in patients with pathologic stage C (T3N0) adenocarcinoma of the prostate.

Patients with localized adenocarcinoma of the prostate gland (CaP) are frequently (approximately 50%) found at radical prostatectomy to have extracapsular disease or positive surgical margins. The management of these patients is a subject of controversy because some question the impact of this manifestation of CaP on patient survival or disease-free survival. Between 1976 and 1991, 241 patients with pathologic stage C (T3N0) were treated in this medical center. Of these 241 patients, 201 (83%) received a planned postoperative pelvic irradiation consisting of 48 Gy given to the prostatic fossa, whereas 40 (17%) patients were treated with radical prostatectomy alone. The two study urologists selected these patients not to receive postoperative irradiation based on intraoperative findings and important prognostic factors. Comparison of treatment outcomes in these two treatment groups is a subject of this report. The 201 patients treated with surgery-radiotherapy (S+RT) combination had a higher pathologic stage, greater incidence of seminal vesicle involvement, p = 0.002, and higher mean and median preoperative prostate-specific antigen level, p < 0.0001, than the 40 surgery (S) alone patients. There was no significant difference in the incidence of higher Gleason's score by the treatment group, p = 0.14. In univariate analysis, there was no significant difference in survival, disease-free survival, and time to failure between the two treatment groups. In multivariate analysis after controlling for pathologic stage and Gleason's score, the 201 adjuvant radiotherapy patients were predicted to have recurrence at 68% (95% confidence interval 39%-118%) the rate of the 40 surgery-alone patients. Local recurrence with or without metastatic disease was found in 10% of surgery-alone patients as compared to 5% in those also receiving postoperative irradiation. Treatment tolerance was very good with minor radiotherapy complications only. There was no significant difference in the incidence of incontinence between the two treatment arms. In summary: (a) The use of moderate-dose postoperative radiotherapy was of low toxicity and it did not increase the incidence of incontinence. (b) Local recurrence was 5% in S+RT and 10% in S-alone patients. (c) In multivariate analysis, S+RT patients had 68% rate of recurrence of S-alone patients. (d) Adjuvant RT probably reduces the risk of recurrence in patients with poor prognostic factors. (e) These data need to be interpreted with caution because of the nonrandomized nature of the study.

Quality of life after radical cystectomy for bladder cancer in patients with an ileal conduit, cutaneous or urethral kock pouch.

PURPOSE: Radical cystectomy for bladder cancer is associated with many changes in bodily function with sexual and urinary dysfunction most prevalent. However, little research has been done on how efforts to improve erectile function relate to quality of life. Also, the psychological benefits associated with continent urinary diversion have not been fully explored. We compared long-term quality of life outcomes among 3 urinary diversion groups, and between patients who had and had not received an inflatable penile prosthesis. MATERIALS AND METHODS: The 224 participating patients completed 4 self-reporting questionnaires, including the profile of mood states, and adapted versions of the sexual history form, body image dissatisfaction scale and quality of life questionnaire. We compared self-reports of emotional distress, global quality of life, sexuality, body image dissatisfaction, urinary diversion problems, and problems with social, physical and functional activities in patients with advanced bladder cancer who underwent urinary diversion, including an ileal conduit in 25, cutaneous Kock pouch in 93 and urethral Kock pouch in 103. Patients who had or had not received an inflatable penile prosthesis after cystectomy were also compared in regard to quality of life variables. RESULTS: Regardless of type of urinary diversion the majority of patients reported good overall quality of life, little emotional distress and few problems with social, physical or functional activities. Problems with urinary diversion and sexual functioning were identified as most common. After controlling for age analysis of variance showed no significant differences among urinary diversion subgroups in any quality of life area. However, t tests controlling for age indicated that penile prosthesis placement was significantly associated with better sexual function and satisfaction. CONCLUSIONS: Quality of life appears good in these long-term survivors of advanced bladder cancer. The type of urinary diversion does not appear to be associated with differential quality of life. Findings suggest that physicians may wish to discuss urinary diversion problems and sexual dysfunction as long-term correlates of radical cystectomy for bladder cancer. Furthermore, they may also wish to discuss the option of erectile aids in men with erectile dysfunction after cystectomy.

Adjuvant radiotherapy in patients with pathologic Stage C (pT3N0) adenocarcinoma of the prostate.

OBJECTIVES: This report is an update on the outcomes in the management of pathologic Stage C (T3N0) prostate cancer (CaP) with postoperative irradiation. METHODS: Between 1976 and 1994, 311 patients with pathologic Stage C CaP were treated with radical prostatectomy. Pathologic stage was as follows: C1, 60 patients (19%), C2, 146 patients (47%), and C3, 105 patients (34%). Gleason score was 2 to 4 in 10 patients (3.2%), 5 to 6 in 121 (39%), 7 in 101 (32%), and 8 to 10 in 76 (24%); median prostate-specific antigen (PSA) level was 11.9 ng/mL. Postoperative irradiation consisted of a median dose of 48 Gy. Follow-up was up to 18 years (median 5). RESULTS: The 10-year actuarial survival was 81% and 10-year disease-free survival was 51%. Pathologic stage and Gleason score were independently predictive of recurrence, each with P >0.001 after controlling for the other. Patients with pathologic Stage C3 and Gleason score 7 to 10 were in the worst prognostic category and had 5.4 times the risk of recurrence compared with patients with pathologic Stage C1-C2, Gleason score 2 to 6. Preoperative PSA was a good (P = 0.02) predictor of disease-free survival. Clinical recurrence was seen in 28 patients (9%), including 10 (3.2%) with local recurrence. PSA recurrence (PSA greater than 0.05 ng/mL) developed in 68 patients (22%). CONCLUSIONS: With the known limitations of a nonrandomized clinical trial, on the basis of the experience of this study we recommend the use of moderate dose, limited-field postoperative radiotherapy in patients with pathologic Stage C disease with Gleason score greater than 4.

Orthotopic urinary diversion with preservation of erectile and ejaculatory function in men requiring radical cystectomy for nonurothelial malignancy: a new technique.

PURPOSE: Nerve sparing techniques to preserve sexual function in men undergoing cystoprostatectomy have been well documented. The patient who desires to remain fertile with ejaculatory function poses an additional challenge. We describe a new technique for radical cystectomy and orthotopic diversion with preservation of the vasa deferentia, seminal vesicles, posterior prostate and neurovascular bundles. MATERIALS AND METHODS: Four men with a median age of 26 years presented with bladder pathology necessitating cystectomy, including signet ring carcinoma of the bladder dome, leiomyosarcoma of the anterior bladder wall, leiomyosarcoma of the lateral bladder wall, and extensive polypoid cystitis glandularis of the trigone and posterior wall refractory to conservative and transurethral management. All patients wished to maintain fertility and ejaculatory function. We detail the surgical technique of extirpation of the bladder and anterior proximal prostate en bloc with preservation of the vasa deferentia, seminal vesicles, posterior prostate and neurovascular bundles as well as construction of an orthotopic reservoir. RESULTS: Followup ranges from 4 months to 5 years. All patients remain completely continent and void to completion without difficulty. Erectile function is normal in all cases. Of 3 patients who ejaculate antegrade 1 has fathered a child. The remaining patient ejaculates retrograde. There has been no tumor recurrence. CONCLUSIONS: The technique of cystectomy with preservation of the vasa deferentia, seminal vesicles, posterior prostate and neurovascular bundles is an excellent option in men with nonurothelial malignancy or another pathological condition that necessitates cystectomy, and in whom preservation of fertility and potency is desirable. All of our patients are fully potent and achieve ejaculation. Even the patient with retrograde ejaculation remains fertile. In terms of practicality semen retrieval from urine is much simpler than epididymal sperm aspiration and in vitro fertilization.
