Extended versus segmental colectomy for mid-transverse colon cancers: An unsolved question

We read with interest the paper by Park et al [1]. The authors analyzed a population of 107 patients with mid-transverse colon cancer (MTCC), who underwent either extended hemicolectomy (EC=70) or segmental colectomy (SC=37) [1]. No statistically significant difference was found in perioperative and long-term outcomes, following propensity score matching [1]. In particular, the authors underlined the lack of significant differences in 3-year disease-free survival (DFS; 86.5% vs. 90.9%, p = 0.675) and 5-year overall survival (OS; 87.4% vs. 93.0%, p = 0.349) [1].
