Intradiverticular bladder cancer: CT imaging features and their association with clinical outcomes

Abstract

Objectives: To evaluate if computed tomographic (CT) features of intradiverticular bladder cancer can predict clinical outcome.

Methods: Retrospective study of 34 patients with intradiverticular bladder cancer. Two radiologists independently evaluated all CT exams.

Results: CT tumor length and width were significantly associated with survival for both readers [hazard ratios (HRs) 1.31-1.62, P<.001-.043]. No other tumor features were significantly associated with survival. The interreader agreement for the assessment of CT features was fair to substantial (k=0.34-0.78, concordance correlation coefficient=0.56-0.66). There was no association between transurethral resection pathology stage and survival (HR 2.10, P=.21).

Conclusions: In patients with intradiverticular bladder cancer, the tumor length and width measured on the pretreatment CT predicted survival.

Keywords: Bladder cancer; Bladder diverticulum; CT; Imaging.
