The study aims to provide global research productivity on lung 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 research started with the selection of terms on “Lung cancer”. Three terms- Lung Cancer, Lung Neoplasm, and Pulmonary 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 related to Lung cancer research from 1989-2017 was retrieved and downloaded in the excel file after restricting the country to India and Iran. Later, Microsoft Excel, STATA, and EViews 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 from 1989 to 2017. Further, authorship patterns were analyzed using the authorship collaboration and collaborative coefficient methods. The findings of the study show that there is a strong and considerable relationship between the Gross Domestic Production (GDP) of nations and publication productivity. The annual growth rate is slow in the onset as compared to the later years, which is a positive sign of the improvement in the research productivity of India and Iran while as relative growth rate shows a decrease, doubling time shows an increasing trend in both nations towards the end of 2017. Authors prefer to work in collaboration rather than individually.
