BACKGROUND: Although extended colectomy is often chosen for patients with transverse colon cancer, the optimal surgical approach for mid-transverse colon cancer has not been established.
METHODS: We identified patients who underwent a transverse (TC) or an extended colectomy (EC) for mid-transverse colon cancer between 2004 and 2014. To adjust for potential selection bias between the groups, a propensity score matching analysis was performed.
RESULTS: A total of 103 patients were included, of whom 63% underwent EC (right 47%, left 17%) and 37% TC. EC patients tend to have worse short-term outcomes. Although fewer lymph nodes were harvested after TC, 5-year overall (OS) ad disease-free survival (DFS) was comparable between the groups. When comparing long-term outcomes stage-by-stage, worse OS and DFS were seen in stage-II. All stage-II patients died of a non-cancer-related cause and recurrence occurred in pT4 TC patients who did not receive adjuvant therapy. The propensity-matched cohort demonstrated similar postoperative morbidity, but more laparoscopic procedures in EC. Additionally, TC tumors were correlated with poorer histopathological features and disease recurrence was only seen after TC.
CONCLUSION: Our study underlines the oncological safety of a transverse colectomy for mid-transverse colon cancer. Although TC tumors were associated with poorer histopathological features, survival rates were comparable.
