Upper tract urothelial recurrence following radical cystectomy for transitional cell carcinoma of the bladder: an analysis of 1,069 patients with 10-year followup.

PURPOSE: Risk factors for upper tract recurrence following radical cystectomy for transitional cell carcinoma of the bladder are not yet well-defined. We reviewed our population of patients who underwent radical cystectomy to identify prognostic factors and clinical outcomes associated with upper tract recurrence. MATERIALS AND METHODS: From our prospective database of 1,359 patients who underwent radical cystectomy we identified 1,069 patients treated for transitional cell carcinoma of the bladder between January 1985 and December 2001. Univariate analysis was completed to determine factors predictive of upper tract recurrence. RESULTS: A total of 853 men and 216 women were followed for a median of 10.3 years (maximum 18.5). There were 27 (2.5%) upper tract recurrences diagnosed at a median of 3.3 years (range 0.4 to 9.3). Only urethral tumor involvement was predictive of upper tract recurrence. In men superficial transitional cell carcinoma of the prostatic urethra was associated with an increased risk of upper tract recurrence compared with prostatic stromal invasion or absence of prostatic transitional cell carcinoma (p <0.01). In women urethral transitional cell carcinoma was associated with an increased risk of upper tract recurrence (p = 0.01). Despite routine surveillance 78% of upper tract recurrence was detected after development of symptoms. Median survival following upper tract recurrence was 1.7 years (range 0.2 to 8.8). Detection of asymptomatic upper tract recurrence via surveillance did not predict lower nephroureterectomy tumor stage, absence of lymph node metastases or improved survival. CONCLUSIONS: Patients with bladder cancer are at lifelong risk for late oncological recurrence in the upper tract urothelium. Patients with evidence of tumor involvement within the urethra are at highest risk. Surveillance regimens frequently fail to detect tumors before symptoms develop. However, radical nephroureterectomy can provide prolonged survival.

Laparoscopic distal ureterectomy and anastomosis for management of low-risk upper urinary tract transitional cell carcinoma: preliminary results.

OBJECTIVE: To determine the surgical feasibility and early oncological outcomes of laparoscopic distal ureterectomy in patients with low-grade upper urinary tract transitional cell carcinoma (UUT-TCC). PATIENTS AND METHODS: We retrospectively reviewed patients treated laparoscopically with conservative management for a UUT-TCC between 2001 and 2005. We collected data on gender, age, mode of diagnosis, smoking, history of bladder cancer, complications, tumour site, size, stage, grade, hospital stay, recurrence and progression. RESULTS: Data were analysed for six patients with a mean (range) age of 68.5 (54-76) years. Four patients had a diagnostic ureteroscopy with biopsy. The operative duration was 173.3 (120-240) min, the estimated blood loss was 75 (50-200) mL and the length of ureteric resection was 5.23 cm. Two patients required a psoas hitch. JJ stents were maintained for 25.8 (15-30) days. The hospital stay was 6 (5-8) days. There were minor complications in three patients after surgery. The follow-up was 32 (17-46) months. The tumour size was 1.7 (0.8-2.6) cm. There were low-grade tumours in four patients and pTa in five. All patients are alive and free of disease; there were no anastomotic strictures. Two patients developed a recurrence, one in the ipsilateral renal pelvis and one in the bladder. CONCLUSION: Laparoscopic distal ureterectomy with direct re-implantation is technically feasible for low-risk UUT-TCC (i.e. low-grade, noninvasive), in the properly selected patient. Early oncological outcomes are promising but strict surveillance protocols must be followed.

Upper urinary tract tumour after radical cystectomy for transitional cell carcinoma of the bladder: an update on the risk factors, surveillance regimens and treatments.

Urothelial carcinoma is characterized by multiple, multifocal recurrences throughout the genitourinary tract; approximately 3% of patients treated by radical cystectomy (RC) for invasive transitional cell carcinoma (TCC) of the bladder will subsequently develop a subsequent TCC in the upper urinary tract (UUT) urothelium. Metachronous upper UUT tumours (mUUT-TCC) typically occur as a late oncological event (>3 years after RC). The vast majority of mUUT-TCCs are detected only after the progression to tumour-related symptoms, e.g. haematuria, flank pain or pyelonephritis, despite strict adherence to surveillance protocols. Failure of imaging and cytology to detect most asymptomatic tumours has led to questions about the need for routine UUT surveillance. Some authors have advocated a more tailored approach to surveillance after RC, targeting high-risk patients and with limiting imaging in those patients at lowest risk of developing a subsequent UUT-TCC. mUUT-TCCs are most common in patients with TCC in the ureter or urethra, and with organ-confined bladder cancer. Although the prognosis is generally poor, long-term survival can be achieved in a subset of patients after radical nephroureterectomy (NU). Minimally invasive techniques, e.g. ureteroscopic and percutaneous resection, have been proposed as renal-sparing alternatives to radical surgery for patients with low-stage and -grade de novo UUT-TCC. However, oncological control of renal-sparing therapies in those with high-risk mUUT-TCC remains largely unconfirmed. Until oncological outcomes equivalent to the standard, radical NU, are reported in patients after RC, conservative treatment strategies should be avoided.

Oncologic control after open or laparoscopic nephroureterectomy for upper urinary tract transitional cell carcinoma: a single center experience.

OBJECTIVES: To determine the surgical and oncologic outcomes in patients who underwent either open nephroureterectomy (ONU) or laparoscopic nephroureterectomy (LNU) for upper urinary tract transitional cell carcinoma. METHODS: We performed a retrospective review of data for patients who underwent ONU or LNU for upper urinary tract transitional cell carcinoma from 1994 to 2004 at one institution. The recorded data included sex, age, mode of diagnosis, smoking, history of bladder cancer, type of surgery, complications, tumor site, tumor size, tumor stage, tumor grade, length of hospital stay, recurrence, and progression. We also determined the recurrence and survival rates. RESULTS: We reviewed the data for 46 patients. The median age was 70 years. Seven patients had a history of bladder cancer. Overall, 26 patients underwent ONU and 20 LNU. No differences in the complication rate (15% versus 15%) were observed. The median hospital stay was 4 days (range 3 to 6) after LNU and 9 (range 7 to 12) after ONU (P <0.001). The tumor stage and grade were independent prognostic factors for survival on multivariate analysis (P <0.05). The 5-year disease-specific survival rate was 89.4% for low-grade tumors and 63.1% for high-grade tumors (P = 0.04). ONU was associated with high-grade (P = 0.02) or invasive (P = 0.001) tumors. The 5-year tumor-free survival rate after ONU and LNU was 51.2% and 71.6%, respectively (P = 0.59). CONCLUSIONS: LNU does not affect the mid-term oncologic control and enables a shorter hospital stay. It can be recommended as an alternative to ONU in the management of low-risk upper urinary tract transitional cell carcinoma (Stage T1-T2 and/or low-grade disease). However, long-term follow-up is necessary to recommend it for highly invasive tumors (Stage T3-T4 or N+).

Salvage radical prostatectomy: quality of life outcomes and long-term oncological control of radiorecurrent prostate cancer.

PURPOSE: We review our 20-year experience with salvage radical prostatectomy to determine prognostic variables predictive of oncological control of radiorecurrent prostate cancer. Using a standardized questionnaire we also evaluate outcome data regarding the long-term sexual and urinary effects of salvage radical prostatectomy. MATERIALS AND METHODS: Between 1983 and 2002 salvage radical prostatectomy was performed in 51 patients with locally recurrent prostate cancer following definitive radiotherapy. Clinical information was obtained from a prospective database. Quality of life data were collected using the UCLA Prostate Cancer Index, a validated, patient administered instrument. RESULTS: At 5 years 47% of patients were progression-free without androgen deprivation therapy. Among patients with pT2 disease 100% were progression-free at 5 years, compared with 35% of patients with pT3N0 disease or higher and 0% of patients with node positive (pTxN+) disease (p < 0.001). Preoperative PSA 5.0 ng/ml or less was predictive of organ confined disease, and strongly associated with prolonged progression-free and overall survival (p < 0.001 and 0.01, respectively). Mean urinary function scores for patients with or without an artificial urinary sphincter compared favorably with scores reported after standard, nonsalvage prostatectomy. Sexual dysfunction was nearly uniform in patients undergoing standard salvage radical prostatectomy but implantation of a penile prosthesis was associated with a clinically significant improvement in sexual function. CONCLUSIONS: When initiated early in the course of recurrent disease, salvage radical prostatectomy provides excellent oncological control of radiorecurrent prostate cancer without the need for androgen ablation. Implantation of an artificial urinary sphincter and inflatable penile prosthesis devices in patients with postoperative urinary incontinence or erectile dysfunction results in significantly improved quality of life parameters.

[Place of laparoscopic nephroureterectomy in the treatment of upper urinary tract transitional cell carcinoma]. / Place de la néphrourétérectomie laparoscopique dans le traitement des carcinomes urothéliaux de la voie excrétrice urinaire supérieure.

The current reference treatment for upper urinary tract transitional cell carcinoma is open nephroureterectomy via a lumbar incision and an iliac incision with resection of a large bladder cuff: Since the first laparoscopic nephroureterectomy performed in 1991, several teams have studied this approach for the treatment of urinary tract tumours. Laparoscopy has the advantage of decreased morbidity for the patient and allows early return to work. Recent published series do not demonstrate any difference in terms of cancer control between open and laparoscopic nephroureterectomy. However, the follow-up of laparoscopic nephroureterectomy is still limited and the safety of this technique has not been fully demonstrated. It therefore appears preferable to limit the indications for laparoscopic nephroureterectomy to small and/or low-grade tumours to avoid excessive manipulation of large transitional cell carcinomas in a gaseous atmosphere that can predispose to dissemination during dissection. Diagnostic ureteroscopy has therefore become a useful tool in the preoperative assessment. Biopsies can determine the tumour grade and guide the surgeon's choice of surgical approach.

The prognostic and staging value of lymph node dissection in the treatment of invasive bladder cancer.

Regional lymph node dissection (LND) at the time of radical cystectomy is an essential component of the surgical management of invasive bladder cancer and might provide diagnostic and therapeutic benefits for both node-negative and node-positive patients. The benefits obtained in pathologically node-negative patients might result from more complete resection of undetected micrometastases or from a more meticulous surgical technique. Advanced nodal disease also seems to be amenable to thorough surgical resection in a subpopulation of patients with bladder cancer. Despite the growing body of evidence to support the role of a more extended LND, no guidelines regarding the optimal boundaries of LND have been established. An increased number of resected nodes and wider LND boundaries have been associated with improved local disease control and prolonged survival. Additionally, mapping series indicate that the common iliac and presacral nodal regions are more frequently involved with tumor metastases than previously recognized. Efforts to limit any unnecessary dissection in patients at low risk for metastases--a tailored approach--has been proposed, but remains unproven. From the available evidence, the most reliable diagnostic and therapeutic approach to LND includes the routine extended LND in all patients undergoing cystectomy with curative intent.

The importance of an extended lymphadenectomy in the management of high-grade invasive bladder cancer.

The role of a regional lymphadenectomy in the surgical management of high-grade invasive bladder cancer has evolved over the last several decades. A growing body of evidence suggests that an extended lymph node dissection may provide, not only improved prognostic information, but also a clinically significant therapeutic benefit for both lymph node-positive and -negative patients undergoing radical cystectomy. The extent of the primary bladder tumor, number of lymph nodes removed and the lymph node tumor burden are important prognostic variables in patients undergoing cystectomy. In addition, the concept of lymph node density may further improve stratification of lymph node-positive patients. The historical development and contemporary rationale for an extended pelvic lymphadenectomy in patients undergoing radical cystectomy are reviewed.

The evolving role of pelvic lymphadenectomy in the treatment of bladder cancer.

Regional lymphadenectomy is integral to the surgical management of high-grade invasive bladder cancer. A growing body of evidence suggests that a lymph node dissection may provide not only improved prognostic information, but also a clinically significant therapeutic benefit for both lymph node positive and negative patients undergoing radical cystectomy. While the inclusion of lymph node resection in conjunction with radical cystectomy for patients with clinically negative nodes is well accepted, the extent of the nodal dissection remains highly contentious. Similarly, the benefit of node dissection for patients with advanced disease and gross adenopathy or for those with superficial disease (Ta, T1 or TIS) remains a topic of heated debate. This review describes the historical evolution of lymphadenectomy in the surgical treatment of bladder cancer and provides a comprehensive review of the current literature addressing the role of lymph node dissection in the treatment of bladder cancer.
