Minimum surgical volume to ensure 5-year survival probability for six cancer sites in Japan.

ABSTRACT:

Background

In Japan, the government designates hospitals specialized in cancer care, requiring them to perform 400 surgeries annually without requiring surgical volume per cancer site. This study aimed to estimate the site-specific minimum surgical volume per year based on its associations with 5-year survival probability.

Methods

The data of 64,402 patients who had undergone surgery for six types of cancers (including esophageal, stomach, colorectal, pancreatic, lung, and breast cancers) at designated cancer care hospitals in Osaka between 2007 and 2011 were analyzed. The hospitals were categorized by the average annual surgical volume per cancer type (e.g., 0-4, 5-9, 10-14…). We estimated the adjusted 5-year survival probability per surgical volume category using multivari
