Relation between residence place and long-term prognosis of colorectal cancer patients in a single-center:a real-world data study based on DACCA
Objective To analyze the distribution,prognostic differences,and characteristics of patients with colorectal cancer(CRC)from 2007 to 2022 based on the current version of the Database from Colorectal Cancer(DACCA),so as to provide a basis for clinical decision-making.Methods The eligible CRC patients based on the established screening criteria from the updated DACCA were collected.The distribution and survival status of CRC patients in different residence places were analyzed.The residence places included 21 cities(prefectures)within Sichuan Province.Results A total of 5 416 cases that met the screening criteria from 2007 to 2022 were collected.Among these,CRC patients were predominantly concentrated in Chengdu(44.77％),Meishan(5.78％),and Nanchong(4.56％)cities.A heatmap depicting the superimposed trend of CRC patients origins revealed the distribution of patients was basically divided into eastern and western regions along the axis of"Mianyang-Chengdu-Yaan cities".The majority of patients(5 359 cases,98.95％)was distributed in the eastern region,while a few in the western region(57 cases,1.05％).The patients in the eastern region were more high clustered(especially Chengdu city),while those in the western region was sporadically dispersed,and the patients in the western region increased slowly without aggregation.The 1,3,and 5-year cumulative overall survival rates of the CRC patients in the DACCA were 96.2％,89.7％,and 85.1％,respectively.The multivariate Cox proportional hazards regression model showed that the male,age ≥ 35-year old,adenocarcinoma(mucinous adenocarcinoma as a reference),poorly differentiated degree,pTNM stages Ⅲ and Ⅳ,obstruction,and perforation were the risk factors for median overall survival shortening in the CRC patients(all P＜0.05).The survival curve of patients with CRC drawn by Kaplan-Meier method showed that the overall survival of CRC patients in different cities(prefectures)had no statistical differences as compared with the integral CRC patients(P＞0.05),except for Neijiang city(was worse than that of the integral CRC patients,P＜0.05).Conclusions Based on data analysis for the DACCA from 2007 to 2022,the majority of CRC patients clusters in the eastern region.Chengdu city exhibits a high clustering,while the western region shows a sporadic distribution without aggregation phenomena.It is found that the cumulative overall survival of CRC patients in Neijiang city is worse than that of the integral CRC patients,while which in the other cities(prefectures)was relatively close to that of the integral CRC patients in Sichuan Province.
