| description | <i>Background and Objectives:</i> An increasing number of studies have shown the influence of primary tumor location of colon cancer on prognosis, but the prognostic difference between colon cancers at different locations remains controversial. After comparing the prognostic differences between left-sided and right-sided colon cancer, the study subdivided left-sided and right-sided colon cancer into three parts, respectively, and explored which parts had the most significant prognostic differences, with the aim to further analyze the prognostic significance of primary locations of colon cancer. <i>Materials and Methods:</i> Clinicopathological data of patients with colon cancer who underwent radical surgery from the Surveillance, Epidemiology, and End Results Program database were analyzed. The data was divided into two groups (2004–2009 and 2010–2015) based on time intervals. Two tumor locations with the most significant survival difference were explored by using Cox regression analyses. The prognostic difference of the two locations was further verified in survival analyses after propensity score matching. <i>Results:</i> Patients with right-sided colon cancer had worse cancer-specific and overall survival compared to left-sided colon cancer. Survival difference between cecum cancer and sigmoid colon cancer was found to be the most significant among six tumor locations in both 2004–2009 and 2010–2015 time periods. After propensity score matching, multivariate analyses showed that cecum cancer was an independent unfavorable factor for cancer specific survival (HR [95% CI]: 1.11 [1.04–1.17], <i>p</i> = 0.001 for 2004–2009; HR [95% CI]: 1.23 [1.13–1.33], <i>p</i> < 0.001 for 2010–2015) and overall survival (HR [95% CI]: 1.09 [1.04–1.14], <i>p</i> < 0.001 for 2004–2009; HR [95% CI]: 1.09 [1.04–1.14], <i>p</i> < 0.001 for 2010–2015) compared to sigmoid colon cancer. <i>Conclusions:</i> The study indicates the prognosis of cecum cancer is worse than that of sigmoid colon. The current dichotomy model (right-sided vs. left-sided colon) may be inappropriate for the study of colon cancer. |
