The study aims to provide an insight into the global research productivity in prostate 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 commenced with the selection of terms on “Prostate cancer”. Three terms- Prostate Cancer, Prostate Neoplasm, and Prostatic 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 prostate cancer research from 1989-2017 was retrieved and downloaded in the excel file. Later, Microsoft Excel software was 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 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 as is evident from the values of Collaboration Coefficient and Degree of Collaboration.
