Oncological Followup After Radical Cystectomy for Bladder Cancer—Is There Any Benefit?

PurposeTumor recurrence after radical cystectomy for bladder cancer can be detected in an asymptomatic patient by regular followup or in a symptomatic patient by symptom guided examination. To our knowledge it is still unknown whether detecting tumor recurrence at an asymptomatic stage offers a better survival rate.Materials and MethodsA total of 1,270 radical cystectomies for bladder cancer were performed at a single institution between January 1, 1986 and December 2006. All patients had regular followup examinations with chest x-ray and abdominal ultrasound every 3 months, computerized tomography of the abdomen every 6 months, and bone scan and excretory urography every 12 months. Additional examinations were required for symptomatic disease. We analyzed the first site and date of tumor recurrence. Survival was compared using the log rank test.ResultsThe 20-year recurrence rate was 48.6% in the complete series. Tumor recurrence developed in 444 patients, including 154 asymptomatic and 290 symptomatic patients, with a mean time after radical cystectomy of 20 and 17.5 months, respectively. The most frequent symptoms were pain, ileus, acute urinary retention, hydronephrosis with flank pain, hematuria, neurological symptoms and a palpable mass. Of the 444 patients 182 (41%) had local recurrence and 324 (73%) had distant failure at the time of first recurrence. The overall survival rate 1, 2 and 5 years after first recurrence was 22.5%, 10.1% and 5.5% in asymptomatic patients, and 18.9%, 8.2% and 2.9% in symptomatic patients, respectively (log rank not significant).ConclusionsThis study fails to demonstrate a survival benefit for detecting tumor recurrence early at an asymptomatic stage by regular followup examinations. These data show that symptom guided followup examinations may provide similar results at lower cost.
