Clinicopathological Characteristics and Incidence of Gastric Cancer in Eastern India: A Retrospective Study

Purpose: To study the association of gastric cancer with various clinicopathological traits in eastern India which can be used as an important factor for further analysis, understanding of the diseases and amelioration of patients.

Methods: The retrospective study includes the patients who underwent subtotal or total gastrectomy from surgical oncology department of Chittaranjan National Cancer Institute (hospital) of West Bengal, India between 2014 and 2018. The study includes 751 gastric cancer patients from Chittaranjan National Cancer Institute. We used electronic hospital records to collect data on various clinical parameters and other information. We used Microsoft Office Excel 2007 spreadsheets for the statistical analyses.

Results: Incidence of gastric cancer is associated with mid age (40-59 years) group male patients and lymph node metastasis. Frequency of gastric cancer is highest in the antrum (42.21%). Of the mid age group gastric cancer patients, 35.02% were having much high risk of developing diffused type of adenocarcinoma (P < 0.00001). Tobacco intake in form of smoking was found as an important risk factor in gastric cancer development with risk ratio and odds ratio of 1.18 and 3.14 respectively.

Conclusion: Collectively, the results of the present study confirm that incidence of diffused type of gastric cancer is increasing as an alarming rate in mid age group male patients and tobacco intake in the form of smoking as an independent risk factor for this type of cancer in eastern India. This result can be used to manage gastric carcinoma in future prospective clinical studies and in patient's improvement.
