To evaluate if computed tomographic (CT) features of intradiverticular bladder cancer can predict clinical outcome.
Retrospective study of 34 patients with intradiverticular bladder cancer. Two radiologists independently evaluated all CT exams.
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).
In patients with intradiverticular bladder cancer, the tumor length and width measured on the pretreatment CT predicted survival.
评估膀胱憩室内癌的计算机断层扫描（CT）特征能否预测临床结局。
对34例膀胱憩室内癌患者进行回顾性研究。两名放射科医生独立评估所有CT检查。
两位阅片者均发现CT肿瘤长度和宽度与生存率显著相关[风险比（HRs）为1.31 - 1.62，P <.001 -.043]。无其他肿瘤特征与生存率显著相关。阅片者之间对CT特征评估的一致性为中等至高度（k = 0.34 - 0.78，一致性相关系数 = 0.56 - 0.66）。经尿道切除术病理分期与生存率之间无关联（HR 2.10，P =.21）。
对于膀胱憩室内癌患者，治疗前CT测量的肿瘤长度和宽度可预测生存率。
