Although studies have found a significant prognostic impact of cancer location for right-sided colon cancers compared with those of the left-side, evidence is lacking in a Japanese population. Therefore, we investigated 5-year net survival in colon cancer by tumor site in a Japanese population.<h4>Methods</h4>Diagnoses obtained between 2006 and 2008 in 21 population-based cancer registries from the Monitoring of Cancer Incidence in Japan (MCIJ) project were used. Colon cancer patients were categorized as having right-sided (C18.0-18.4) or left-sided colon cancer (C18.5-C18.7). We calculated the 5-year net survival for subjects diagnosed from 2006 until 2008 by anatomical subsite according to sex, age groBMC cancerPrognostic impact of tumor location in colon cancer: the Monitoring of Cancer Incidence in Japan (MCIJ) project.PMC650981317K15840H29-political-general-016H29-political-general-015Nakagawa-Senda HMatsuda THori MIto HfalsePrognostic impact of tumor location in colon cancer: the Monitoring of Cancer Incidence in Japan (MCIJ) project.<h4>Background</h4>Colorectal cancer (CRC) is globally one of the most common cancers.
