Objective To understand the relation between the occupation and long-term prognosis of the patients with colorectal cancer (CRC) based on the Database from Colorectal Cancer (DACCA). Methods The selected updated DACCA database as of June 29, 2022 was used for this study. The included patients were assigned into intellectual occupations group (intellectual group) and manual occupations group (manual group) referring to relevant regulatory documents in China. The survival status of the intellectual group and the manual group was compared, and then were stratified by pTNM stage. Results A total of 1 974 patients were included from the DACCA database according to the selection criteria, 349 of whom in the intellectual group and 1 625 of whom in the manual group. The intellectual group had higher 5-year cumulative overall survival rate (92.1% vs. 84.5%, P<0.001) and disease-specific survival rate (92.1% vs. 85.8%, P=0.002), as well as higher 10-year cumulative overall survival rate (72.4% vs. 55.2%, P<0.001) and disease-specific survival rate (75.4% vs. 59.1%, P<0.001) compared to the manual group. The stratified analysis by pTNM stage found that, for the patients with pTNM Ⅲ stage, the 5- and 10-year cumulative overall survival rates of the intellectual group were higher than those of the manual group (94.0% vs. 82.3%, P<0.001; 67.1% vs. 43.7%, P=0.014), simultaneous the 5- and 10-year cumulative disease-specific survival rates were the same as the overall survival rate (94.0% vs. 83.5%, P=0.001; 69.5% vs. 47.9%, P=0.026). Furthermore for the the patients with pTNM Ⅱ stage , it was found that the the 10-year cumulative disease-specific survival rate of the intellectual group was higher than that of the manual group (93.5% vs. 78.7%, P=0.009).Conclusions From the analysis results of this study, occupation might be related to long-term prognosis in CRC cancer patients. A general trend is that the long-term prognosis of patients with intellectual occupations might be better than that of patients with manual occupations, and this difference might be relatively marked in the patients with pTNM Ⅱ and Ⅲ stages, but it needs to be autious and objective.
