Bladder-sparing surgery in locally advanced nonurological pelvic malignancy.

Abstract：

INTRODUCTION:The urinary bladder is commonly involved in pelvic malignancy. The incidence of apparent extension into adjacent organs in locally advanced colorectal malignancy is 5-12%. It is not known with other pelvic malignancy. No guidelines are available for its management. Often a dilemma exists between cystectomy and a bladder-sparing procedure. We studied the validity of bladder-sparing surgery (BSS) in locally advanced nonurological pelvic malignancy. METHODS:Hospital records of patients who underwent BSS along with other surgeries (abdomino-perineal resection, anterior resection, anterior exenteration, debulking surgery and total pelvic exenteration) from January 1992 to May 2003 were reviewed. RESULTS:BSS was done in 15 patients. 10 had locally advanced colorectal malignancy, 3 with soft tissue masses of the lateral pelvic wall, 1 had ovarian malignancy and the other had residual mass following radiotherapy and chemotherapy of cancer cervix. In those with locally advanced colorectal malignancy, symptoms suggestive of lower urinary tract involvement were present in 8 (80%). Urine examination and ultrasonography was not helpful in suggesting bladder involvement, unlike CT scan of abdomen and pelvis. Preoperative cystoscopy showed endoscopic evidence of bladder involvement in 7 (87.5%). Bladder was involved supratrigonally in 7. Partial cystectomy was done in 9 patients. The left ureter was involved in 6 patients, and they required ureteric reimplantation. Palliative transurethral resection was done in 1 patient with tumor infiltration at the bladder neck and prostate. 50% patients had bothersome lower urinary tract symptoms at 1 year. One patient died in the immediate postoperative period due to a nonurological cause. Overall 3-year survival rate was 40%. CONCLUSION:Unlike primary bladder cancers these lesions are not multifocal and hence en block conservative bladder-sparing surgery can be offered. Preoperative CT scan or MRI can predict lower urinary tract involvement and help in decision-making by both surgeon and patient. The ultimate decision for bladder sparing is based on intraoperative findings. Sparing the bladder might provide better quality of life by avoiding urinary diversion without altering survival.
