The incidence of gallbladder cancer (GBC) is very high in India and it increases day by day due to population aging and changing of life style. The current study scrutinized the trend analysis of gallbladder cancer of Dibrugarh district. The registered gallbladder cancer data for the period of 14 years, i.e., 2003-2016, is collected from Population-Based Cancer Registry (PBCR), Upper Assam. The Mann Kendall and Sen's Slop test is performed to analyze the gallbladder cancer data. A total of 716 number of patients with gallbladder cancer were included and overall gallbladder cancer was found highest among patients of age 50-70 years, accounting for 56.84% (n = 407). The disease was most common in females (69.13%) in comparison to males (30.87%) and most of the patients were from urban areas (66.89%). Majority (29.19%) of the patients had completed their primary education whereas 22.07% were illiterate. Mean of age at the time of diagnosis was 54.51 ± 12.29 years which was 57.43 ± 12.19 for male and 53.21 ± 12.13 for female. The time trends and patterns of gallbladder cancer have striking differences within the country as well as in the state of Assam. Large, focussed, inclusive studies are required in India to assess early detection and diagnosis of gallbladder cancer in the country.
