Abstract:
Objective To determine the association of gallstone,cholecystectomy and colorectal cancer.Methods From 2000 through 2007,a historical cohort study was carried out in the check analysis of the cumulative incidence of colorectal cancer of 3809 gallstone patients who had had cholecystectomies (cholecystectomy sub-group),1764 gallstone patients who had not had cholecystectomies(noncholecystectomy sub-group)and 8187 nongallstone patients(control group)were also included in the analysis of the incidence of colorectal cancer.Results(1)The cumulative incidence of colorectal cancer of the gall-stone group was 0.43 ％(24/5573)while that of the control group was 0.13 ％(11/8187)(x2 =11.879,P =0.001).(2)The cumulative incidence of colorectal cancer in cholecystectomy sub-group was 0.45％(17/3890)while that of the non-cholecystectomy sub-group was 0.40％(7/1764)(x2=0.069,P =0.793).(3)The cumulative incidence of colorectal cancer was 0.23％(8/3467)in gallstone patients with a conrse ＜ 15 years,while that was 0.76％(16/2106)when the course ≥ 15 years(x2 =8.550,P =0.003).(4)Serum triglyceride level elevated in 20.83％(5/24)colorectal cancer cases of gallstone group,however serum triglyceride level elevated only in 5.86％(325/5549)of gallstone group with non-colorectal cancer cases(x2 =9.621,P =0.002).(5)The incidence of colorectal cancer in gallstone group was not related to gender,age,overweight,hypertension,diabetes mellitus and dysfunction of liver(x2 =1.444,P =0.229;x2=7.833,P=0.251;x2 =1.151,P=0.283;x2 =0.797,P=0.372;x2 =0.939,P=0.332;x2 =2.103,P =0.147).(6)The ratio of rectal cancer,right colonic cancer,left colonic cancer and multifocal carcinoma were 41％(10/24),38％(9/24),17％(4/24)and4％(1/24),respectively.Conclusions Gallstone is a high risk factor of colorectal cancer irrespective of whether or not a cholecystectomy is carried out.Over fifteen-years course of gallstone and hypertriglyceridemia significantly increases the risk of the colorectal cancer in gallstone patients.The incidence of rectal cancer and right colonic cancer is more frequently seen in gallstone related colorectal cancer.
