assessed in Japan, especially for esophageal, biliary tract, and pancreatic cancer, although …

The relationship between hospital volume and patient outcome is globally known; thus,
hospital volume is widely used as a quality indicator. In Japan, however, recent studies on …

According to former population-based studies in Japan, there is considerable interhospital
differences in terms of survival for stomach1) 2), lung1), breast1), ovarian3) and uterine4) …

Background Many studies have assessed the volume-outcome relationship in cancer
patients, but most focused on better outcomes in higher volume groups rather than …

Background Recent studies reported that hospital procedure volume (ie volume of patients
per hospital receiving a particular treatment) was directly proportional to cancer survival; …

Despite the large number of surgical operations for stomach cancer in Japan, no study
based on data from population‐based cancer registries has been conducted regarding the …

Background: There is limited data on the relationship between hospital volumes and
outcomes with respect to cancer survival in Japan. The primary objective of this study was to …

Background Minimum case volume thresholds for complex cancer operations have been
proposed by the Leapfrog Group. There has been no formal study of how these standards …
