Epidemiology of Gallbladder Cancer in North India - a Radiological Descriptive Study

ABSTRACT

Introduction: Gallbladder cancer (GBC) is one of thecommonest cancers in North India. Despite the high incidence,very little data is available of the staging distribution ofGBC in this region. We aimed at getting a snapshot of thedistribution of GBC at a single high volume centre.Material and Methods: One hundred and forty sevenpatients who were evaluated between 1st July 2017 and 31stOctober 2018 for staging of GBC, were included in this study.Radiological staging was done according to the AJCC TNM8th edition using a standardized reporting format.Results: Majority of patients were females (70%). Fundus ofGB was the most common site of tumor (39.4%) and liver(76.8%) was the most common adjacent organ involved aswell as the most common site of metastatic disease (36%).Only 42 (28.5%) patients had non-metastatic disease.Biliary obstruction was present in 63 (42.8%) patients, withmajority being type 2 hilar blocks (65%). Loco-regional nodalinvolvement was present in 87.1% patients, station 12 nodalinvolvement being most common (76.1%).Conclusion: This is the first study to describe the distributionof GBC stages in the high incidence region of North India.This should provide information for future research andfunding for GBC related research.
