Trends in surgical treatment for prostate cancer: Analysis of National Database Open Data in Japan

We conducted a study to clarify the trends in surgical treatments for prostate cancer in Japan between 2014 and 2020 by analyzing the National Database (NDB) Open Data in Japan. Intriguingly, the number of patients over 70 years old who underwent robotic-assisted radical prostatectomy (RARP) nearly doubled from 2015 to 2019, while that in those 69 years old and younger remained almost constant during the same period. The increase in the number of patients over 70 years of age may reflect the fact that RARP can be safely applied to elderly patients. With the new development and spread of surgery-assisting robots, we can foresee a further increase in the number of RARPs performed for elderly patients in the future.
