Short-term and long-term outcomes after laparoscopic surgery for elderly patients with colorectal cancer aged over 80 years: a propensity score matching analysis

There has been an increase in the percentage of elderly patients with colorectal cancer (CRC). However, few studies have reported the short- and long-term outcomes of laparoscopic surgery for elderly patients with CRC aged over 80 years. This study included 529 patients who underwent laparoscopic resection for clinical stage 0–III CRC at Kobe University Hospital between January 2010 and December 2018. Propensity score matching (PSM) was used to create balanced cohorts of the elderly (aged ≥ 80, n = 113) and the non-elderly (aged
