Patients aged 80 and older undergoing surgery for colon cancer from 2011 to 2017 in an Italian hospital were retrospectively selected. MECC score [Mortality in Elderly patients with Colon Cancer] was calculated summing up the scores relating to: arterial saturation of O2, Systolic Blood Pressure, Heart Rate, WBCs, Albumin, Creatinine. Once CR-POSSUM was calculated, the two scores were compared.
CR-POSSUM is one of the most used surgical scores to predict mortality after colorectal surgery. Its main drawback is the requirement of intraoperative variables, whose collection is time-consuming and prevents from obtaining a purely preoperative risk assessment. The primary aim of the study is to develop a new surgical score using preoperative parameters to predict 30-day mortality after colon cancer surgery in the elderly population. The secondary objective is to analyze its efficacy compared to CR-POSSUM.
