Oncologic outcomes of surgically treated colorectal cancer in octogenarians: a comparative study using inverse probability of treatment weighting (IPTW).

ABSTRACT:

Purpose

Octogenarians constitute a growing number of diagnoses for colorectal cancer. However, the optimal treatment for these increasingly vulnerable octogenarians with colorectal cancer remains a challenging issue. The aim of this study was to evaluate the oncologic outcomes of colorectal cancer, comparing octogenarians (> 80 years) and younger age (60-79 years).

Methods

A total of 657 patients underwent surgery for colorectal cancer between January 2015 and December 2019 at Gangneung asan hospital. Among them, 444 patients over the age of 60 were enrolled. The exclusion criteria were as follows: only local resection, R1 and R2 resection, Stage IV, absence of data in follow-up, concurrent inflammatory bowel disease, concurrent malignancy, and prior history of malignancy.
