Partial cystectomy for muscle invasive urothelial carcinoma of the bladder: a contemporary review of the M. D. Anderson Cancer Center experience.
OBJECTIVE
Partial cystectomy is a surgical option for select patients diagnosed with urothelial carcinoma. We review our experience with partial cystectomy for muscle invasive urothelial carcinoma to assess local control and survival rates.


METHODS
From 1982 to 2003 a total of 37 patients with muscle invasive urothelial carcinoma underwent partial cystectomy with curative intent. Reviewed data included history of superficial tumors, presence of variant histology, tumor location, clinical stage, pathological stage, presence of carcinoma in situ, adjuvant therapy and disease status.


RESULTS
The 5-year overall, disease specific and recurrence-free survival rates were 67%, 87% and 39%, respectively. Mean followup was 72.6 months (range 6 to 217). Of the 37 patients 19 (51%) did not have tumor recurrence, 9 (24%) had superficial recurrence in the bladder that was treated successfully and 9 (24%) had recurrence with advanced disease. A total of 24 patients (65%) had an intact bladder with no evidence of disease after a median of 53 months. There were 6 patients (16%) who died of bladder cancer, 3 of whom died of late recurrence of muscle invasive cancer (41, 44 and 138 months after partial cystectomy). On multivariate analysis higher pathological stage (HR 3.4, p = 0.04) was associated with shorter recurrence-free survival. A history of superficial tumors (p <0.01) and clinical stage (p = 0.01) was associated with advanced recurrence-free survival. The use of adjuvant chemotherapy (HR 0.18, p = 0.03) was associated with prolonged advanced recurrence-free survival, however adjuvant chemotherapy did not impact overall survival.


CONCLUSIONS
Partial cystectomy provides adequate local control of muscle invasive bladder cancer in select patients. Because late recurrence is not uncommon and is potentially life threatening, lifelong followup with cystoscopy is recommended.
