Orthotopic urinary diversion is a viable option in patients undergoing salvage cystoprostatectomy for recurrent prostate cancer after definitive radiation therapy

Contemporary role of palliative cystoprostatectomy or pelvic exenteration in advanced symptomatic prostate cancer

OBJECTIVE

To access the feasibility of palliative cystoprostatectomy/pelvic exenteration in patients with bladder/rectal invasion due to prostate cancer (PC).

PATIENTS AND METHODS

Twenty-five men with cT4 PC were retrospectively identified in the institutional databases of six tertiary referral centers in the last decade. Local invasion was documented by CT or MRI scans and was confirmed by urethrocystoscopy. Oncological therapies, local symptoms, previous local treatments, time from diagnosis to intervention and type of surgical procedure were recorded. Patients were divided into groups: ADT group (12 pts) and 13 pts without any history of previous local/systemic treatments for PCa (nonADT groups). Perioperative complications were classified using the Clavien-Dindo system. Overall survival (OS) was defined as the time from surgery to death from any cause. A Cox regression analysis, stratified for ISUP score and previous hormonal treatment (ADT) was also performed for survival analysis.

RESULTS

Ileal conduit was the main urinary diversion in both cohorts. For the entire cohort, complication rate was 44%. No significant differences regarding perioperative complications and complication severity between both subgroups were observed (p = 0.2). Median follow-up was 15 months (range 3-41) for the entire cohort with a median survival of 15 months (95% CI 10.1-19.9). In Cox regression analysis stratified for ISUP score, no statistically significant differences in OS in patients with and without previous ADT before cystectomy or exenteration were observed (HR 3.26, 95% CI 0.62-17.23, p = 0.164).

CONCLUSION

Palliative cystoprostatectomy and pelvic exenteration represent viable treatment options associated with acceptable morbidity and good short-term survival outcome.

The role of cystoprostatectomy in management of locally advanced prostate cancer: a systematic review

Background

The role of cystoprostatectomy for the treatment of locally advanced prostate cancer (LAPC) was evaluated by a comprehensive review of contemporary literatures.

Methods

A systematic search of English language literatures using PubMed, EMBASE, Web of Science, and Cochrane library, from 1990 to 2018, was performed. Two independent authors reviewed abstracts as well as full-text articles and extracted data from the selected manuscripts.

Results

After the literature research, seven articles with a total of 211 patients were identified. Both 120 cases who received cystoprostatectomy for the primary treatment of LAPC and 91 cases for the salvage surgery after local recurrence were finally included. Overall incidence of positive surgical margins ranged from 25 to 78%. The incidence of major complications caused by the surgery during the follow-up time was limited. It had been reported that among LAPC patients who received cystoprostatectomy combined with adjuvant therapies, 5-year cancer-specific survival rate and 5-year biochemical progression-free survival was up to 87.1% and 62.2%. Moreover, symptoms such as hematuria and other urination dysfunctions, as well as patients’ quality of life were significantly improved after cystoprostatectomy in LAPC patients with the bladder invasion.

Conclusions

Cystoprostatectomy can serve as an alternative to the surgical step of multimodal therapy for highly selected LAPC patients with the bladder invasion, which may improve patients’ symptoms and related quality of life. Therefore, cystoprostatectomy as an option for the treatment of LAPC with the bladder invasion may be feasible and safe with considerable survival outcomes.

Radical cystectomy is the treatment of choice for invasive bladder cancer

[Value of cystoprostatectomy in locally advanced prostate carcinoma]

Patients suffering from locally advanced prostate carcinoma are often stressed by debilitating local symptoms limiting their quality of life. At the same time life expectancy often exceeds several years, whereas urologists and oncologists tend to underestimate their patients' life expectancy. Cystoprostatectomy for locally advanced prostate carcinoma is a reasonable therapeutic option concerning frequency and kind of imminent complications and possibly alleviates or completely eliminates local symptoms in 80% or more. According to the literature cancer-specific 10-year survival rates are 38% or median cancer-specific survival lies between 24 and 31 months. The role of neoadjuvant or adjuvant hormonal therapy, chemotherapy, or radiotherapy has not yet been defined. Mostly after cystoprostatectomy due to locally advanced prostate carcinoma an ileal conduit is formed for urinary diversion, but also orthotopic neobladders or continent pouches are used. Incontinence rates for orthotopic neobladders may reach 50% and more. In synopsis cystoprostatectomy may be a viable therapeutic option for patients suffering from locally advanced prostate carcinoma. It surely is important that the indication for surgery is based on an individual decision.

Urinary diversion: options, patient selection, and outcomes

Improved survival following radical cystectomy for bladder cancer as a result of advancements in combination chemotherapy and surgical technique has resulted in a philosophical change in the surgeon's approach to urinary diversion selection. Aims have evolved from the mere diversion of urine to a functional bowel conduit such as an ileal conduit or ureterosigmoidostomy, to providing the optimal diversion for the patient's quality of life. While quality of life is important, one must also consider the stage of cancer and individual patient comorbidities. Which diversion provides the best local cancer control, the lowest potential for complications (short and long term), and the easiest emotional adjustment in lifestyle while still allowing the timely completion of chemotherapy and therapeutic goals? A multidisciplinary approach to diversion selection that includes the patient, the medical oncologist, radiation oncologist, internist, and surgeon is ideal. We describe the three most commonly used types of diversions today, including conduits, continent cutaneous reservoirs, and orthotopic urethral diversions, as well as issues relative to patient selection and functional outcomes in patients undergoing radical cystectomy for the treatment of bladder cancer.

Superficial and Muscle-Invasive Bladder Cancer: Principles of Management for Outcomes Assessments

Bladder cancer is a heterogeneous disease. Non–muscle-invasive bladder cancer embraces a spectrum of tumors with varying degrees of clinical behavior. Transurethral resection remains the surgical mainstay for the treatment of non–muscle-invasive bladder cancer. In an attempt to decrease the recurrence or progression rate, intravesical chemotherapy or immunotherapy is also used. Radical cystectomy with bilateral pelvic lymph node dissection remains the gold standard for treating muscle-invasive bladder cancer. Over the last decade, the orthotopic neobladder has gained widespread popularity as the preferred mode of urinary diversion in both males and females with similar oncologic and functional outcomes. Well-designed trials with effective chemotherapy have shown a beneficial role for neoadjuvant chemotherapy.

Radikale Salvageprostatektomie bei lokalem Prostatakarzinomrezidiv nach Strahlentherapie

BACKGROUND

Although technically challenging, salvage radical prostatectomy (SRP) for radiorecurrent prostate cancer (PCA) is an effective option in carefully selected patients and offers the chance for cure and long-term survival. Sometimes local progression of PCA with subvesical obstruction following radiation therapy requires radical cystoprostatectomy or bladder-preserving urinary diversion. We present our experience with salvage radical prostatectomy in a group of 28 consecutive patients.

PATIENTS AND METHODS

Between January 2003 and August 2005, 25 patients underwent radical salvage surgery for locally recurrent PCA following external beam radiation (n=14), high-dose brachytherapy (n=8), and low-dose brachytherapy (n=6). All men had biopsy-proved recurrent or persistent PCA associated with PSA progression following radiation therapy. Preoperative imaging studies included bone scintigraphy and computed tomography without evidence of metastatic disease. Of the 28 men, 11 (39%) presented with bothersome irritative voiding dysfunction and rectal discomfort. Life expectancy was >10 years in all cases. We analyzed preoperative symptoms, treatment-associated morbidity, pathohistological findings, and functional and oncological outcome after a mean follow-up of 12.5 (2-29) months.

RESULTS

SRP was performed in all cases without significant intra- and perioperative complications: no rectal lacerations or ureteral lesions were encountered and mean blood loss was 520 (200-950) ml. A total of 21 (75%) men underwent SRP: in 4 cases radical cystoprostatectomy was necessary due to bladder neck infiltration and in 3 men SRP with bladder neck closure and continent appendicovesicostomy was performed due to preexisting urinary stress incontinence. All men with subvesical obstruction experienced significant relief of urgency and significant irritative voiding dysfunction following radical salvage surgery. Pathohistological analysis of the prostatectomy specimen revealed pT1-2b PCA in 19 (67.8%), pT3a/b PCA in 5 (17.8%), and lymph node metastasis or positive surgical margins in 7% of the patients. Two patients demonstrated a pT0 despite positive preoperative biopsies, and 20% demonstrated a Gleason score 8-10. With regard to functional outcome, 25% of the men need 2-3 pads daily whereas 78% of the men are continent. After a mean follow-up of 12.5 (2-29) months, two patients with pT3b and pN1 status exhibit a PSA relapse.

CONCLUSION

Salvage RP or RCx is a technically challenging but feasible surgical approach with curative intent for the treatment of locally recurrent PCA in well selected patients preventing significant local complications such as subvesical obstruction, ureteral obstruction, hematuria, and rectal infiltration. Surgery-associated morbidity and complications are low and not comparable to earlier series. The indication for salvage RP requires positive biopsy and negative imaging studies.

Complications after cystectomy and urinary diversion in patients previously treated for localized prostate cancer

OBJECTIVES

To assess the morbidity associated with radical cystectomy in patients who had previously undergone definitive treatment of prostate cancer.

METHODS

A retrospective review was undertaken, identifying 35 patients undergoing radical cystectomy with a previous history of radical prostatectomy and/or radiotherapy for prostate cancer. The clinical and surgical information was analyzed to assess patient outcomes. Specific attention was given to the rate, severity, and time course of the postoperative complications. In addition, outcomes after orthotopic and continent cutaneous diversion in this patient cohort were examined.

RESULTS

An overall complication rate of 76% was seen in this patient cohort, with 47% of patients experiencing a complication that presented later than postoperative day 30. Radiotherapy was associated with a slightly greater complication rate compared with radical prostatectomy monotherapy (77% versus 71%). Continent urinary diversion (n = 14) was associated with increased morbidity compared with ileal conduit diversion (n = 21). However, a greater percentage of the complications occurring in patients undergoing ileal conduit diversion were major (80% versus 67%).

CONCLUSIONS

Our experience has suggested that radical cystectomy in patients previously treated for prostate cancer with radiotherapy and/or radical prostatectomy may be associated with a greater level of morbidity than previously reported. This finding may be, in part, because a significant portion of complications present in a delayed fashion and, as such, have not been seen in previous reports with limited follow-up. For this reason, careful consideration of these risks is necessary when counseling this patient cohort regarding the decision to undergo radical cystectomy.

Survival after Bladder-Preservation with Brachytherapy versus Radical Cystectomy; A Single Institution Experience

OBJECTIVE

To evaluate the long-term survival following brachytherapy and following cystectomy of patients with invasive bladder cancer treated in our institution.

PATIENTS AND METHODS

Between 1988 and 2000 108 patients with solitary, organ confined T1-T2 invasive bladder cancer of < or = 5 cm were treated with a transurethral resection, and a course of external beam radiotherapy (30 Gy) followed by 40 Gy brachytherapy. The overall and disease specific survival rates of these patients are compared with those of 77 patients with T1-T2 invasive bladder cancer treated with cystectomy between 1988-2003.

RESULTS

The 5/10 year overall survival rates were 62%/50% after brachytherapy and 67%/58% after cystectomy (p = 0.67). The 5/10 year disease specific survival rates were 73%/67% after brachytherapy and 72%/72% after cystectomy (p = 0.28). When adjusted for age, multiplicity, T-stage, N-stage and grade, the 5/10 year overall survival rates were 65%/53% after brachytherapy and 62%/51% after cystectomy, respectively. The adjusted disease specific survival rates were 75%/70% after brachytherapy and 66%/66% after cystectomy.

CONCLUSIONS

This study does not provide evidence regarding survival against the use of bladder preservation with brachytherapy for patients with solitary, T1-T2 invasive bladder cancer of < or = 5 cm diameter, seeking bladder-sparing alternatives to radical cystectomy.

Salvage cystectomy after failure of interstitial radiotherapy and external beam radiotherapy for bladder cancer

OBJECTIVE

To evaluate the long-term results of salvage cystectomy after interstitial radiotherapy (IRT) and external beam radiotherapy (EBRT) for transitional cell carcinoma, and to assess the morbidity and functional results of the different urinary diversions used.

PATIENTS AND METHODS

The records of 27 patients treated with salvage cystectomy in one institution between 1988 and 2003 were retrospectively analysed.

RESULTS

Salvage cystectomy was used after failure of IRT in 14 or EBRT in 13 patients, with a 3- and 5-year survival probability of 46% (95% confidence interval 26-65) and 33 (11-54)%. The 5-year overall survival after cystectomy was 54% after IRT and 14% after EBRT (P = 0.12). Tumour category, response to radiation, American Society of Anesthesiology score, and complete tumour resection had a significant influence on survival. Five of seven patients with incomplete resection died because of local disease, with a median survival of 5 months. There was clinical understaging after radiotherapy in 41% of patients. Nine patients had an orthotopic neobladder, with complete day- and night-time continence in eight and four, respectively. All patients but one had good voiding function. There were early complications in two and late complications in six patients (for Bricker, seven of 14 and none; for Indiana, none of four and two of four). The duration of hospitalization was not influenced by the type of diversion. Erectile function was maintained in four of six patients after a sexuality-preserving cystectomy and neobladder.

CONCLUSIONS

Salvage cystectomy can be performed with acceptable morbidity using any type of urinary diversion. Understaging after radiotherapy is common, but preoperative selection needs improving. A very significant factor for an adverse outcome and death from local tumour recurrence was incomplete resection, suggesting that salvage cystectomy should only be attempted if complete resection is probable.

Salvage therapy for locally recurrent prostate cancer after external beam radiotherapy

The greatest obstacle in the cure of patients with locally recurrent prostate cancer after radiation therapy is the lack of early detection markers. The majority of patients who are candidates for local salvage therapy have locally advanced disease, precluding successful salvage therapy. A low pretreatment prostate specific antigen (PSA) has shown to be a favorable prognostic variable for disease progression, regardless of the specific local salvage therapy used. Of all the local salvage treatment options for these patients, we believe that salvage radical prostatectomy (RP) offers patients the greatest likelihood of a cure. The salvage RP results approach those achieved with standard RP for patients of similar pathologic stage. When patients are treated early in the course of recurrent disease (preoperative PSA < 10 ng/mL), an estimated two-thirds of patients will be disease-free 5 years after salvage RP alone. With better patient selection and continued technical modifications, the morbidity associated with salvage RP has substantially improved. Perioperative complications approach those observed with standard RP and approximately two-thirds of patients will recover urinary continence. Select patients may also recover functional erections when nerve-sparing techniques are used. Salvage cryotherapy and brachytherapy are minimally invasive alternatives to salvage RP. The cancer control results of these procedures appear to be inferior to results achieved with salvage RP. Each of these procedures is associated with significant morbidity and do not appear to provide a clear advantage over salvage RP in terms of posttreatment complications, urinary continence, and erectile function. A long-term cure is possible for patients with locally recurrent prostate cancer after radiation therapy. Local salvage therapy must be instituted early to be successful in the course of progressive disease.

Ileal conduit urinary diversion in patients with previous history of abdominal/pelvic irradiation

Urinary diversion among patients receiving prior radiation is common. Herein, we present our experience with ileal conduit (IC) diversion in patients with a history of prior abdominal and/or pelvic radiation therapy. We analyzed the charts of 177 patients who underwent IC urinary diversion between 1/1994 and 6/2000, and 36 patients were identified who had previously undergone radiation therapy. Decisions to proceed were based on surgeon preference as determined by intraoperative appearance and viability of the selected bowel segment. Chart review included serum studies, upper tract imaging studies, and complications related to diversion. Durability of diversion was determined by examining the interval between urinary diversion and the need for additional procedures. A total of 30 patients with at least 3 months follow-up were identified. Renal function remained stable in 86% (26/30) with a median follow-up of 21.5 months (range 3-63 months). Hydronephrosis was noted preoperatively in 4 patients (13%) who demonstrated stable upper tracts and serum creatinine in the post-operative period. Three patients (10%) developed unilateral hydronephrosis related to tumor recurrence, with one patient demonstrating a rise in baseline serum creatinine. Hydronephrosis was noted in 5 patients (16%) secondary to development of ureteroenteric stricture. Serum creatinine remained stable in 2 patients without intervention with 2 years follow-up. Intervention for obstruction was necessary in 3 patients at 22, 31, and 61 months following diversion. In one patient, an intraoperative decision to use the colon for urinary diversion was made secondary to appearance of small bowel. Minor complications were noted in 9 patients (30%), while 3 patients (10%) experienced major complications in the immediate post-operative period. Five patients (17%) experienced complications potentially related to the use of ileum for urinary diversion. The use of ileum for urinary diversion among patients with a history of radiation appears technically feasible and a viable treatment alternative. Our data support the use of ileum in the majority of patients as evidence by a low complication rate and a high rate of upper tract preservation. In addition, these data imply that a prior history of abdominal and/or pelvic radiation should not serve as the sole determining factor in the selection of bowel segment utilized during urinary diversion.

Salvage prostatectomy in patients who have failed radiation therapy or cryotherapy as primary treatment for prostate cancer

Asymptomatic prostate-specific antigen (PSA) recurrence after radiation therapy for prostate carcinoma poses a diagnostic and therapeutic dilemma for clinicians. Patients with locally recurrent disease can consider treatment options of salvage surgery, cryotherapy, watchful waiting, or androgen deprivation. Of these options, only salvage surgery has been shown to result in long-term disease-free survival for selected patients. However, salvage surgery is associated with significant morbidity, including urinary incontinence and rectal injuries. Ideally, salvage surgery outcomes can be optimized with careful patient selection according to clinical stage, serum PSA levels before radiation and surgery, the medical condition of the patient, and clear expectations of the physician and patient. Among patients with locally recurrent disease, those with localized prostate carcinoma amenable to radical prostatectomy before radiation or cryotherapy would be the most suitable candidates for salvage surgery.

Radical cystectomy for bladder cancer after definitive prostate cancer treatment

OBJECTIVES

To review our perioperative experience with patients presenting with high-risk bladder cancer who had undergone prior therapy for prostate cancer. With the increase in diagnosis and subsequent treatment of prostate cancer, more patients presenting with high-risk bladder cancer have undergone prior therapy for prostate cancer. Radical cystectomy in these patients can be technically challenging and may be associated with added morbidity.

METHODS

A retrospective review of 458 patients treated with radical cystectomy between January 1993 and January 2002 revealed 29 patients (mean age 72 years) who had received definitive treatment for prostate cancer prior to cystectomy for bladder carcinoma. The initial treatment in this cohort was radical prostatectomy or external beam radiotherapy in 12 (41%) and 17 (59%) men, respectively. Cystectomy was performed for transitional cell carcinoma in 25 (86%), small cell carcinoma in 2 (6%), and sarcoma in 2 (6%) patients.

RESULTS

At the time of cystectomy, the mean blood loss was 1175 mL (range 275 to 3500), and the median length of hospitalization was 8 days (range 4 to 23). No intraoperative or perioperative deaths occurred in this cohort. Twenty-seven early complications were identified in 16 (55%) of 29 patients; no rectal injuries occurred. Patients with prior radiotherapy had a higher rate of extravesical bladder carcinoma (60%) than those patients treated with prior prostatectomy (33%). An orthotopic neobladder diversion was created in 5 patients (17%).

CONCLUSIONS

Patients with bladder cancer previously treated for prostate cancer with external beam radiotherapy or radical prostatectomy have an increased risk of perioperative complications compared with patients undergoing cystectomy without prior therapy. This risk is not prohibitive, and radical cystectomy should remain the treatment of choice for high-risk bladder cancer in this population. Furthermore, orthotopic urinary diversion may be a reasonable option and should be considered in select patients.

Salvage radical prostatectomy

Although technically challenging, salvage prostatectomy for radiorecurrent prostate cancer is an effective option in carefully selected patients and offers the best chance for cure and long-term survival. Alternatively, cystoprostatectomy may be indicated in some patients who have a small capacity fibrotic bladder or intractable voiding symptoms related to radiation cystitis. Good long-term results can be expected in this patient group; however, exenterative surgery in patients with locally advanced disease is associated with comparably inferior results and should not be advocated. If cystectomy is necessary, orthotopic urinary diversion can be performed safely in young motivated patients who wish to maintain a better quality of life with associated morbidity. Although the higher rate of incontinence and impotence after salvage procedures may detract from the quality of life, the impact of these long-term complications on the patient's overall well-being is less than previously believed, and most patients are satisfied with their treatment outcome and adjust well to the circumstances, accepting some increased degree of morbidity. This observation emphasizes the value of careful preoperative counseling and the discussion of treatment options and outcomes, which also should incorporate quality of life issues.

What is new in urinary diversion

There have been some suggestions for changes in technique and investigations of the quality of life. As experience has grown, there have been increasing numbers of reports of complications. Careful attention to technique, especially in nerve-sparing cystectomy and orthotopic cystoplasty may reduce the rate of incontinence. Increasing awareness of quality of life issues should improve preoperative counselling of patients, especially those whose underlying condition is not life-threatening.
