The objective of this study was to determine the clinical outcome of patients with invasive transitional cell carcinoma of the bladder and pelvic lymph node metastases treated by radical cystectomy and bilateral pelvic lymphadenectomy in a single institution. From January 1980 to December 1993, 116 patients with transitional cell carcinoma of the bladder underwent bilateral pelvic lymphadenectomy and radical cystectomy at the Montreal General Hospital. Of these patients, 25 (21.6%) were found to have nodal metastases and form the basis of this retrospective analysis. Extent of nodal disease was as follows: 7 (28%) with N1, 17 (68%) with N2, and 1 (4%) patient with N3 disease. Of the 25 patients, 9 (36%) were alive with no evidence of disease and 1 (4%) died at 42 months from cardiovascular disease without clinical evidence of cancer recurrence. The median follow-up interval for these 10 patients was 26.5 months (mean, 31.4 months; range, 7-104 months). Fourteen (56%) patients died of recurrent bladder cancer and one patient was alive with systemic disease at 14 months. The median survival was estimated at 27 months, with 73% alive at 1 year, 51% alive at 2 years, and 33% alive at 3 years. Our data suggests that long-term survival free of disease can be achieved by radical surgery in some patients with node-positive bladder cancer.
