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


Di Paolo, Pier Luigi; Vargas, Hebert Alberto; Karlo, Christoph A; Lakhman, Yulia; Zheng, Junting; Moskowitz, Chaya S; Al-Ahmadie, Hikmat A; Sala, Evis; Bochner, Bernard H; Hricak, Hedvig (2015). Intradiverticular bladder cancer: CT imaging features and their association with clinical outcomes. Clinical Imaging, 39(1):94-98.

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.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
