Abstract
INTRODUCTION: The density of gallbladder carcinoma differs in different parts of the world. It is an aggressive tumor with poor prognosis presenting in advanced stages due to paucity of signs and symptoms. This research was conducted to analyze the frequency of incidental and clinically suspected gallbladder carcinoma with clinicopathological correlation. METHODS: This is a retrospective cohort study conducted in the Department of Pathology, Manipal College of Medical Sciences, Pokhara, Nepal from January 2005 to December 2020. RESULTS: The study included 35 cases of gallbladder carcinoma compiled over a period of 16 years. There were 11 males and 24 females with a male to female ratio of 1: 2.1. Age ranged from 29 to 75 years with a mean age of 56.51 ± 11.38 years. Incidental carcinoma was observed in 26 (74.28%) cases while clinically suspected carcinoma was identified in 9 (25.71%) cases. Gallstone was associated in 14 (40%) cases of incidental carcinoma. Tumor staging of both incidental and clinically suspected carcinomas showed 13 (37.14%) cases in T1 stage, 15 (42.85%) cases in T2 stage and 7(20%) cases in T3 stage. CONCLUSION: Our analysis established prevalance of gallbladder carcinoma from 5th to 7th decades with female predominance and higher association of gallstones in incidental carcinoma. The principal histology in incidental carcinoma was well differentiated carcinoma while poorly differentiated carcinoma was encountered only in clinically suspected carcinoma.
