PubMed is a free web literature search service that contains almost 21 millions of abstracts and publications with almost 5 million user queries daily. The purposes of the study were to compare trends in PubMed-indexed cancer and biomedical publications from Egypt to that of the world and to predict future publication volumes.
The PubMed was searched for the biomedical publications between 1991 and 2010 (publications dates). Affiliation was then limited to Egypt. Further limitation was applied to cancer, human and animal publications. Poisson regression model was used for prediction of future number of publications between 2011 and 2020.
Cancer publications contributed 23% to biomedical publications both for Egypt and the world. Egyptian biomedical and cancer publications contributed about 0.13% to their world counterparts. This contribution was more than doubled over the study period. Egyptian and world's publications increased from year to year with rapid rise starting the year 2003. Egyptian as well as world's human cancer publications showed the highest increases. Egyptian publications had some peculiarities; they showed some drop at the years 1994 and 2002 and apart from the decline in the animal: human ratio with time, all Egyptian publications in the period 1991-2000 were significantly more than those in 2001-2010 (P < 0.05 for all). By 2020, Egyptian biomedical and cancer publications will increase by 158.7% and 280% relative to 2010 to constitute 0.34% and 0.17% of total PubMed publications, respectively.
The Egyptian contribution to world's biomedical and cancer publications needs significant improvements through research strategic planning, setting national research priorities, adequate funding and researchers' training.
PubMed是一项免费的网络文献检索服务，包含近2100万篇摘要和出版物，每天有近500万次用户查询。本研究的目的是比较埃及与世界范围内PubMed索引的癌症和生物医学出版物的趋势，并预测未来的出版物数量。
在PubMed中检索1991年至2010年（出版日期）之间的生物医学出版物。然后将所属机构限定为埃及。进一步限定为癌症、人类和动物出版物。采用泊松回归模型预测2011年至2020年期间未来的出版物数量。
癌症出版物在埃及和世界的生物医学出版物中均占23%。埃及的生物医学和癌症出版物占世界同类出版物的约0.13%。在研究期间，这一贡献增加了一倍多。埃及和世界的出版物逐年增加，从2003年开始迅速增长。埃及以及世界的人类癌症出版物增长最为显著。埃及的出版物有一些特点；它们在1994年和2002年有所下降，除了动物与人类的比例随时间下降外，1991年至2000年期间埃及的所有出版物均显著多于2001年至2010年期间（所有P<0.05）。到2020年，埃及的生物医学和癌症出版物相对于2010年将分别增加158.7%和280%，分别占PubMed总出版物的0.34%和0.17%。
埃及对世界生物医学和癌症出版物的贡献需要通过研究战略规划、确定国家研究重点、充足的资金和研究人员培训来显著提高。
