The safety and prognosis of radical surgery in old patients of colorectal cancer / 中华普通外科杂志

ABSTRACT

Objective:To evaluate the safety and feasibility of radical surgery and explore prognostic factors affecting cancer-specific survival (CSS) in elderly patients with colorectal cancer (CRC).Methods:From Jan 2010 to Dec 2020, a total of 372 elderly (aged over 80 years) CRC patients who underwent curative resection at the National Cancer Center were enrolled. Preoperative clinical features, perioperative outcomes and postoperative pathological characteristics were collected.Results:In the multivariable COX regression analysis, BMI ≥30 kg/m 2 ( HR2.30, 95% CI 1.27-4.17, P=0.006) and N1-N2 stage ( HR 2.97,95% CI1.48-5.97, P=0.002) correlated with worse CCS. Conclusions:The results of this study demonstrated that radical resection for CRC is safe and feasible for patients over 80 years of age. BMI and N stage were independent prognostic factors for elderly CRC patients after radical resection.
