International Journal of Preventive Medicine (Int J Prev Med)2008-7802022015040414911491EN20150404<strong>Background:</strong> Global burden of cancer is on rise and trends and pattern of cancers are rapidly changing different geographic and population groups. Gall bladder cancers are emerging with<br />increasing proportion among select areas and groups and understanding these variations are important for appropriate strategies and interventions. However, absence of a well‑developed universal cancer registry system in India, institution based secondary data analysis can generate<br />useful information. The present study was conducted to determine the trend and pattern of cancer cases (with special reference to gall bladder cancer) treated in a tertiary care hospital in northern part of West Bengal.<br /><strong>Methods:</strong> Record based cross‑sectional study was conducted in Department of Radiotherapy, North Bengal Medical College and Hospital. All newly registered cases between (2010 and 2012)<br />were reviewed.<br /><strong>Results:</strong> A total of 2058 cancer cases were recorded during the 3‑year period. Of these, major types of cancers were oro‑pharynx (16.1%), breast (15.4%), cervix (13.2%), lung (12.7%), gall bladder (6.5%) stomach cancer (6.4%), etc., Increasing proportions was observed for breast<br />and gall bladder cancers. The proportion of gallbladder cancer cases in 2010, 2011, and 2012 were 3.8%, 7.3% and 7.8%, respectively. Among 134 gall bladder cancer cases, 93.3% were<br />females, 85.1% alcoholics, 57.4% had a history of fatty liver, 94% had adeno/adenosquamous<br />carcinomas, and 65.7% were metastatic in nature.<br /><strong>Conclusions:</strong> Increasing trend is observed in gall bladder cancer cases emphasizing the need for further large scale studies.<br /><strong>Keywords:</strong> Changing trends and patterns, gall bladder cancers, secondary datahttp://ijpm.mui.ac.ir/index.php/ijpm/article/view/1491http://ijpm.mui.ac.ir/index.php/ijpm/article/download/1491/1773
