Growing burden of cancer in West Bengal: a retrospective study Dr, Annesha Lahiri, PGT, IPGMER and SSKM Hospital, Kolkata Dr Sounik Das, PGT, IPGMER and SSKM Hospital, Kolkata Dr Bikramjit Chakraborty, Asst Professor, IPGMER and SSKM Hospital, Kolkata Dr Santanu Pal, Professor, IPGMER and SSKM Hospital, Kolkata Purpose- To analyse the burden of cancer and its patterns in West Bengal in a single institution based cancer registry. Background- Cancer has become one of the leading causes of death worldwide. Analysis of the growing burden and changing pattern according to geographical locations helps in designing epidemiological studies and planning of cancer prevention and control programs. In India, since cancer is not a notifiable disease, various cancer registries under the NCRP carry out active data collection. In this study, we have attempted to understand the distribution of cancer burden in West Bengal based on data collected from patients attending the Out Patient Department of Radiotherapy, IPGMER and SSKM Hospital, Kolkata over a period of one year. Materials and methods- The data of a total of 3342 new patients who attended the Out Patient Department of Radiotherapy, IPGMER and SSKM Hospital, Kolkata from June 2016 to June 2017 were analysed. Medical records were evaluated and relevant information regarding age, sex, primary site of cancer and demography were extracted. 304 patients were excluded from analysis, due lack of of knowledge of primary site of malignancy or benign nature of tumour. Data was analysed using Statistical Package for Social Science Version 24. Results- Proportion in males: females was 1.48:1. In males, four most common primary sites of malignancy; Lung (16.2%), Oral cavity (5.6%), Larynx (5.4%), Stomach (5.0%). Similarly in females; Breast (27.3%), Cervix (14.6%), Gall bladder (8.8%), Ovary & Lung (4.9%) Highest burden of cancer is from the following districts:- Kolkata - 16.4% (most common- lung, breast & gall bladder cancers) South 24Pgs - 14.6%(Lung, breast, stomach cancers) Howrah - 13.6 % North 24Parganas - 7.4% Murshidabad - 6.9% Geographical distribution of four most common malignancies in our study population Lung Cancer (11.9%) Kolkata (20.5%), South 24Parganas (17.5%) Howrah (11.4%) Breast Cancer (10.4) Howrah & Kolkata (17.3%), South 24Parganas (12.9%), North 24Parganas (12.2%) Cervical Cancer (5.5%) Murshidabad (12.0%), West Mednipur(10.7%), Bankura & South 24Parganas(9.3%) Oral cavity (4.4%) Howrah(21.3%), Kolkata (14.8%), South 24Parganas(13.1%) CA Gall Bladder (4.0%) Kolkata (18.2%), Howrah (14.5%), South 24Parganas (12.7%) Conclusions- Males were found to be almost 1.5 times more afflicted by cancer than females. Highest cancer burden is found to be from Kolkata, closely followed by South 24 Parganas. When compared with data from Population based cancer registry, Kolkata, 2006-07, lung and breast cancer remain the most common malignancies in males and females respectively, though the subsequent pattern differs, especially in males, where number of prostate cancer patients has reduced and carcinoma stomach has risen. Among lung cancers, in general, squamous is the major histology. However, adenocarcinoma is catching up in urban areas like Kolkata(1.3 : 1) (ratio in rural areas like East Mednipur 4.5:1 & Murshidabad 4:1). Majority of the most commonly occurring malignancies, lung, breast, oral cavity and gall bladder cancers occur more in urban and suburban areas like Kolkata, South & North 24 Parganas, Howrah whereas cancer of the cervix appears to be from Murshidabad, Mednipur, Bankura. As the data was collected from a tertiary care centre in Kolkata, there is possibility of demographical bias. Also, IPGMER is one of the three brachytherapy referral institution for the entire state of West Bengal at the time of study, which might result in biased data of carcinoma cervix. However, there is scope for further studies, integrating data from other government medical colleges, private health care institutes in the various districts for a more comprehensive result.
