Abstract:
Objective To understand the characteristics and trends of clinical epidemiology of colorectal cancer in recent years.Methods The data of 849 patients with colorectal cancer confirmed by pathology in Hongqi Hospital of Mudanjiang Medical College and Cancer Hospital of Mudanjiang City from January 2010 to December 2015 were collected and analyzed by chi square test and variance analysis.Results In recent years,the patients with colorectal cancer were aging (F~ =2.471,P ＜ 0.05).Though the elderly (＞ 60 years old) people were the main population (65.6 ％,557/849),the young (＜ 40 years old) patients with colorectal cancer still accounted for 3.5 ％ (30/849).The rectum was the most common site where the carcinoma arose (56.54 ％,480/849).There was a significant difference between male and female patients in the location and pathological type of tumor (x2 =10.294,P =0.006;x2 =10.468,P =0.015).The incidence of left and right colon was increased [20.02 ％ (170/849) and 23.44 ％ (199/849),x2 =29.023,P =0.004],and the proportion of adenocarcinoma was increased (x2 =40.203,P =0.001).Conclusion The number of elderly patients with colorectal cancer in Mudanjiang region of China is increased significantly in recent years.The adenocarcinoma is the most common pathological type,and its incidence is increasing in recent 5 years.Thus healthy education and colorectal cancer prevention should be strengthened.
