![]() ![]() ![]() Globally, 5-year observed survival rates were higher in Seoul, Republic of Korea (1993–1997 56.8% and 54.3% for colon and rectum cancers, respectively), Zhejiang province (2005–2010 52.9% for colon cancer), Tianjin (1991–1999 52.5% for colon cancer), Shanghai (2002–2006 50.0% for rectum cancer) of China, and in Japan (1993–1996, 59.6% for colorectal cancer). Estimates of observed and relative survival rates of colorectal cancer by sex, period, and country were extracted from original studies to describe the temporal patterns and trends from the late 1990s to the early 21st century. We performed a systematic search of China National Knowledge Infrastructure (CNKI), Wanfang Data, PubMed, Web of Science, EMBASE, and SEER and collected all population-based survival studies of colorectal cancer (up to June 2020). This review will describe the global patterns and trends of colorectal cancer survival, using data from the population-based studies or cancer registration. ![]()
