To investigate the research status of radiation oncology in China through survey of literature in international radiation oncology journals and retrospectively compare the outputs of radiation oncology articles of the three major regions of China-Mainland (ML), Taiwan (TW) and Hong Kong (HK).
Radiation oncology journals were selected from "oncology" and "radiology, nuclear & medical image" category from Science Citation Index Expand (SCIE). Articles from the ML, TW and HK were retrieved from MEDLINE. The number of total articles, clinical trials, case reports, impact factors (IF), institutions and articles published in each journals were conducted for quantity and quality comparisons.
A total 818 articles from 13 radiation oncology journals were searched, of which 427 are from ML, 259 from TW, and 132 from HK. Ninety-seven clinical trials and 5 case reports are reported in China. Accumulated IF of articles from ML (1,417.11) was much higher than that of TW (1,003.093) and HK (544.711), while the average IF of articles from ML is the lowest.
The total number of articles from China especially ML increased significantly in the last decade. The number of articles published from the ML has exceeded those from TW and HK. However, the quality of articles from TW and HK is better than that from ML.
通过调查国际放射肿瘤学期刊中的文献，研究中国放射肿瘤学的研究现状，并回顾性比较中国大陆（ML）、台湾（TW）和香港（HK）三个地区放射肿瘤学文章的产出。
从科学引文索引扩展版（SCIE）的“肿瘤学”和“放射学、核医学与医学影像学”类别中选择放射肿瘤学期刊。从 MEDLINE 检索 ML、TW 和 HK 的文章。对总文章数量、临床试验、病例报告、影响因子（IF）、机构以及每个期刊发表的文章进行数量和质量比较。
共检索到 13 种放射肿瘤学期刊的 818 篇文章，其中 427 篇来自 ML，259 篇来自 TW，132 篇来自 HK。中国报告了 97 项临床试验和 5 项病例报告。ML 的文章累积 IF（1417.11）远高于 TW（1003.093）和 HK（544.711），而 ML 的文章平均 IF 最低。
过去十年，中国（尤其是 ML）的文章总数显著增加。ML 发表的文章数量已经超过了 TW 和 HK。然而，TW 和 HK 的文章质量要好于 ML。
