Surgery lengthens survival for collecting duct carcinoma: analysis of hospital-based cancer registry data in Japan.

ABSTRACT:

Background

To identify the prognosis of Japanese patients with collecting duct carcinoma (CDC).

Methods

We used a hospital-based cancer registry data in Japan to extract CDC cases that were diagnosed in 2013, histologically confirmed, and determined the first course of treatment. We further investigated treatment modalities and estimated overall survival (OS) by the Kaplan-Meier method.

Results

A total of 61 CDC patients were identified. The 5-year OS rate for all CDC patients who were diagnosed in Japan during 2013 was 23.6% (95% CI: 15.0-37.4), with a median OS of 14 months (95% CI: 12-24). The 5-year OS rate for CDC patients at stages I, III, and IV were 53.0% (95% CI: 29.9-94.0), 35.7% (95% CI: 19.8-64.4), and 3.4% (95% CI: 0.5-23.7), respectively. Noteworthy, the
