The study aims to provide an insight into the global research productivity in stomach cancer with an in-depth analysis of the growth & development of India and Iran. The study focuses on the authorship collaborative patterns among Indian and Iranian medical scientists as well. The study was conceived with the selection of terms on “Stomach cancer”. The terms- “Stomach Cancer, Stomach Neoplasm, Gastric Cancer, and Gastric Neoplasm” were selected from the Medical Subject Headings (MeSH) to retrieve the data from the Web of Science (WoS). The Boolean Operator “OR” was executed to retrieve the records. The data was retrieved from 1989-2017 and downloaded in the excel file after restricting the country to India and Iran. Later, Microsoft Excel and STATA software were used to analyze the data. Three important means- annual growth rate (AGR), relative growth rate (RGR), and Doubling Time (DT) have been used to trace the development of literature. Further, authorship patterns were analyzed using the authorship collaboration and collaborative coefficient methods. The findings of the study show that Japan has the highest contribution (16,616; 19.89%) followed by the USA (16,195; 19.38%) and China (15,683; 18.768%) respectively in the field of Stomach Cancer research. India stands at 15th position and Iran at 22thposition with 1104 (1.32%) and 718 (0.86%) publications respectively. The annual growth rate of India and Iran is slow in the onset as compared to the later years, which is a positive sign of the improvement in the research productivity. The collaborative patterns show that medical scientists prefer to work in collaboration.
