OBJECTIVE: To evaluate oncological outcomes of patients with carcinoma in situ (CIS) exclusively at radical cystectomy (RC) and no previous history of ≥T1 disease.
PATIENTS AND METHODS: Patients undergoing RC with curative intent for CIS between 1971 and 2008 at the University of Southern California were included if they met all the following criteria: (i) pathological CIS-only disease at RC, (ii) preoperative clinical stage cCIS and/or cCIS + cTa, and (iii) no previous history of lamina propria invasion (≥pT1). Kaplan-Meier plots were used to estimate the probabilities of recurrence-free survival (RFS) and overall survival (OS).
RESULTS: Of the 1964 consented patients 52 met the inclusion criteria with a median (range) follow-up of 8.5 (0.008-34) years. A median (range) of 36 (10-95) lymph nodes were identified per patient but no metastases found. Estimated 5- and 10-year RFS rates were 94% and 90%, respectively and estimated 5- and 10-year OS rates were 85% and 66%, respectively. Different mechanisms of recurrence were found in four (8%) patients after a median (range) interval of 2.4 (0.6-7.1) years. While two patients had metachronous recurrence within the urinary tract, the first of the other two had early systemic recurrence and the second late local recurrence.
CONCLUSIONS: We noticed excellent outcomes after RC for CIS-only disease. However, patients may have synchronous and/or develop metachronous tumours, as well as local and/or distant/systemic recurrence that can be cured but may also lead to fatal outcomes.
