Abstract: ObjectiveTo analyze Chinese oncology papers of 2012 included by Science Citation Index (SCI) and to facilitate domestic oncology researchers to better master the foreign periodical information and publish research results. MethodsChinese oncology papers included by SCI in 2011 and 2012 were retrieved, by using SCIExpanded database. The periodical distribution, subject distribution, organization distribution, fund and citations were analyzed. ResultsIn 2011, 6570 papers were included by SCI, while 9226 were included in 2012, with the increase rate of 40.426%. The major language was English, and the most frequent literature type was article. The amount of source journals  increased from 668 in 2011 to 749 in 2012. PLoS One published the most amount of literature both in 2011 and in 2012. The periodical with the highest impact factor (IF) in 2011 was Nature Genetics (IF=35.209), while in 2012 was Nature (IF=38.597). The university with the most amount of published literature was Sun Yatsen University (653, 7.078%), and the corresponding medical institution was PLA General Hospital (113, 0.932%) and the corresponding research institute was Chinese Academy of Medical Sciences (316, 3.425%). The most funded project was National Natural Science Foundation with the rate of 46.339% (1949/4206) in 2011 and 40.000% (3290/8225) in 2012. The total citation frequency was 36 569 in 2011 and 18 945 in 2012. ConclusionOver the past two years, Chinese oncology papers included by SCI make great progress, in terms of quantity and quality. English is the main written language, and there are more source journals but less journals with high IF.
