Prognostic impact of postoperative adjuvant chemotherapy on elderly patients with colorectal adenocarcinoma: A propensity score matching study.

Background And Aim: Currently, the primary treatment modality for patients with colorectal adenocarcinoma (CRA) is radical surgery combined with postoperative adjuvant chemotherapy (PAC). However, many elderly patients decline PAC due to concerns about their underlying physiological condition, and the impact of PAC on the prognosis of elderly patients remains uncertain.

Methods: We extracted data from the SEER database for CRA patients aged 75 and above between 2010 and 2019.
