Profiles of gall bladder cancer reported in the hospital cancer registry of a Regional Cancer Center in the North-East India.

Background: The incidence of gall bladder cancer (GBC) is very high in this part of the world and there is little information on the descriptive epidemiology of GBC from our population. Methods: A retrospective study on the data set of hospital cancer registry was analyzed. The data set consisted of patient information registered during the period of January 2011 to December 2012. The cases included for the present study were histologically confirmed and radiologically diagnosed cases of GBC. All the cases were retrospectively analyzed for gender, age, urban-rural residences, religion of patients and their educational levels. Descriptive statistics was calculated and Chi square test was done to see the significance differences among categories. Results: A total of 837 cases of GBC were registered, F:M was 2.33, median age in females and males was 54 and 50 years respectively, majority of cases in both the genders were seen in 50-59 years of age, 81.1% patients were from rural areas and 18.8% from urban areas, Chi square on comparison with other cancers showed p<0.05, and there was no major religious and educational pattern of GBC seen in our population. Conclusion: In our population females are at high risk especially past 40 years of age and rural population with its varied environmental, lifestyles and infective agents should be investigated for possible risk factor in the causation of GBC.
