Abstract: ObjectiveTo analyze Chinese oncology papers included by Chinese biomedical literature database (CBM) and science citation index (SCI), and to comprehensively and objectively reflect the current situation of Chinese oncology literatures published in domestic and international journals. MethodsChinese oncology papers were retrieved by using CBM and SCI. A comparison analysis was made from the respects of subject distribution, district distribution, organization distribution and high citation situation. Results67 071 papers of 2012 were retrieved from CBM database, while 9226 papers were indexed by SCI. In terms of district distribution, the first three districts were Jiangsu (6707), Guangdong (4897) and Beijing (2214) in CBM database, while in SCI database, they were Beijing (2214), Shanghai (2008) and Guangdong (1393). The institute with the most amount of literature is university, respectively 9725 and 5755. Moreover, the mostly funded project is National Natural Science Foundation (4710, 35.38%; 3290, 35.68%). ConclusionThe 2012 Chinese oncology literatures published in domestic journals has advantage with respect to quantity, compared with the international published journals. However, there exists a bigger difference in terms of quality. Through the comparative analysis, the medical researchers in our country will have some implications in the research orientation.
