Abstract
This review article examines 1,368 publications on prostate cancer in India, as covered in Scopus database during 2004-13, experiencing an annual average growth rate of 18.77% and citation impact of 5.23. The world prostate cancer output (89,994 publications) came from several countries, of which the top 15 (United States, United Kingdom, Germany, Canada, Italy, Japan, and China) accounts for 94.80% share of the global output during 2004-13. India’s global publication share was 1.52% and hold 14 th rank in global publication output during 2004-13. The Indian prostate cancer output came from several organizations and authors, of which the top 20 and 19 contributed 41.81% and 24.05% share, respectively, during 2004-13. India’s international collaborative share in prostate cancer was 23.39%, which decreased from 24.42% to 22.98% from 2004-08 to 2009-13. Medicine accounted for the largest share (59.50%) of output in prostate cancer followed by biochemistry, genetics and molecular biology (40.13%), pharmacology, toxicology & pharmaceutics (27.63%), chemistry (8.55%), agricultural and biological sciences (4.31% share), and immunology and microbiology (2.70% share) during 2004-13. Diagnosis, screening, chemotherapy, radiotherapy, pathology and prognosis together account for 60.24% publications share among treatments methods used in Indian prostate cancer research during 2004-13. Only Delhi, Maharashtra, Uttar Pradesh and Tamil Nadu together contributed 57.82% share in Indian publications output in prostate cancer during 2004-13. The authors stressed the need for developing national policy for prostate cancer which should take care of screening for detection and diagnosis, management and treatment options of the prostate cancer patients in India.

The prostate gland is covered in a layer of connective tissue called the prostatic capsule and is made up of different types of cells: (i) gland cells that produce the fluid portion of semen, (ii) muscle cells that control urine flow and ejaculation and (iii) fibrous cells that provide the supportive structure of the gland
Summary
The prostate gland is part of a man's reproductive and urinary systems. It is oval shaped with a rounded tip and its size varies (with age) from the size of a walnut to a small apple. The prostate cancer incidence varies across different geographical regions It is very high in developed regions such as Australia/New Zealand and North America (Age Standardized Rates (ASR) 111.6 and 97.2 per 100,000 respectively). It studied research output and global contribution of different countries in world output It mainly studied India’s cancer literature growth trends and explored the application of Bradford’s Law of Scattering for identifying core journals and Lotka’s Law for author productivity in Indian literature. Examined the articles in 39 issues of Indian Journal of Cancer during 2003-12 It studied the literature growth, author productivity, authorship pattern, average length of articles and country collaboration of cancer research in India. Growth of world and Indian research output by type of publication; Citation pattern of the Indian research output; Contribution, global publication share and citation impact of top 15 most productive countries; International collaboration share of publication of top 15 most productive countries and the extent of inter-country collaborative linkages among them and to identify the leading collaborative partners and their share in India’s output; Distribution of Indian research output by broad subject areas and study their growth and decline; Indian prostate cancer output by treatment methods and their distribution by geographical areas; Publication productivity and citation impact of most productive twenty Indian institutions and nineteen authors; and Leading media of communication
