ABSTRACT
INTRODUCTION: We aimed to enumerate the rate of pelvic recurrence following radical cystectomy at university-affiliated hospitals in Canada. METHODS: Canadian, university-affiliated hospitals were invited to participate. They were asked to identify the first 10 consecutive patients undergoing radical cystectomy starting January 1, 2005, who had urothelial carcinoma stages pT3/T4 N0-2 M0. The first 10 consecutive cases starting January 1, 2005 who met these criteria were the patients submitted by that institution with information regarding tumour stage, age, number of nodes removed, and last known clinical status in regard to recurrence and patterns of failure. RESULTS: Of the 111 patients, 80% had pT3 and 20% pT4 disease, with 62% being node-negative, 14% pN1, and 27% pN2; 57% had 10 or more nodes removed. Cumulative incidence of pelvic relapse was 40% among the entire group. CONCLUSIONS: This review demonstrates a high rate of pelvic tumour recurrence following radical cystectomy for pT3/T4 urothelial cancer.
ABSTRACT
Plasmacytoid variant of urothelial bladder carcinoma is rare. We report a case with a detailed discussion of features that help characterize this variant. A 50-year-old man originally presented with gross hematuria. Resections at that time revealed a grade I-II superficial urothelial carcinoma. He did not return for follow-up until recently, three years later, when he presented with recurrent gross hematuria. An extensive tumor was identified on cystoscopy. Resection revealed a high-grade non-invasive papillary urothelial carcinoma. CT scan revealed a large urinary bladder solid mass with bilateral hydronephrosis. Metastatic workup was negative. The patient underwent a radical cystectomy with creation of ileal conduit. Final pathology revealed plasmacytoid variant of urothelial carcinoma with extensive vascular invasion and extension to the perivesical adipose tissue. We present a rare variant of urothelial carcinoma with comprehensive analysis of the morphological and immunophenotypic clues that characterize this variant.
