Abstract
Carcinoma of the gallbladder is the third most common malignancy of the gastrointestinal tract in the Eastern Uttar Pradesh and Western Bihar regions of India. The main source of drinking water in this region is the river Ganges, which is heavily polluted with agricultural pesticides. Organochlorine pesticides were estimated in bile by gas liquid chromatography in 60 patients (30 carcinoma of the gallbladder and 30 cholelithiasis) to observe its association with aetiopathogenesis of carcinoma of the gallbladder. The mean biliary concentration of benzene hexachloride (BHC) was found to be significantly higher in carcinoma of the gallbladder (0.0471 ppm) than in cholelithiasis (0.0352 ppm) (P < 0.04). The mean biliary concentration of dichlorodiphenyltrichloroethane (DDT) was also significantly higher in carcinoma of the gallbladder (0.418 ppm) than in cholelithiasis (0.0103 ppm) (P < 0.03). Biliary aldrin and endosulfan concentrations were higher in carcinoma of the gallbladder (0.0008 and 0.00132 ppm) than in cholelithiasis (0.0005 and 0.0126 ppm) but the difference was statistically not significant (P < 0.06 and P < 0.9). The levels of pesticides in blood did not show significant differences in either carcinoma of the gallbladder or cholelithiasis. Significantly high biliary BHC and DDT concentrations suggest that these pesticides might be associated with gallbladder carcinogenesis.
