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.

Objective To update our previous analysis of the clinical and pathological impact of the change in the submission of lymphadenectomy specimens from en bloc to 13 separate anatomically defined packets, which took place at the University of Southern California in May 2002, and to determine whether lymph node (LN) packeting resulted in any change in oncological outcomes. Patients and Methods A total of 846 patients who underwent radical cystectomy (RC) with super-extended LN dissection for cTxN0M0 bladder cancer between January 1996 and December 2007 were identified. Specimens of 376 patients were sent en bloc (group 1), and specimens of 470 patients were sent in 13 separate anatomical packets (group 2). Results The pathological tumour stage distribution and the proportion of LN-positive patients (group 1: 82 patients [22%] versus group 2: 99 patients [21%]; P = 0.80) were similar between the two groups: the median [range] number of total LNs identified increased significantly (group 1: 32 [10–97] versus group 2: 65 [10–179]; P < 0.001). LN density decreased (group 1, 11% versus group 2, 4%; P = 0.005). The median [range] number of positive LNs removed was similar (group 1: 0 [0–30] versus group 2: 0 [0–97]; P = 0.87). No nodal stage shift was observed. The 5-year overall survival (group 1: 58% versus group 2: 59%; P = 0.65) and recurrence-free survival rates (group 1: 68% versus group 2: 70%; P = 0.57) were similar. Conclusions The incidence of patients with positive LNs remained unchanged, regardless of how the LN specimen was submitted. Submitting 13 separate nodal packets significantly increased the total LN yield, but did not result in a significant increase in the number of positive LNs or a consecutive nodal stage shift and did not affect oncological outcomes. Based on these results LN density is not an accurate prognosticator.
