[Evidence-based surgical management for early colon cancer].

In recent years, the incidence of early colon cancer (ECC) in China showed a rising trend. Accurate definition of ECC is of great significance for disease assessment, treatment decision-making and prognosis judgment. Although endoscopic resection has become an option in the treatment of ECC, surgical intervention is still needed for tumor residue and high risk pT1 tumors in order to prevent recurrence and metastasis. There is no consensus on indication, timing, radical resection range and tumor location of ECC surgery. The innovation of laparoscopic surgical techniques strongly promoted the progress of ECC minimally invasive surgery. Postoperative follow-up should be systematic, standardized and individualized, based on the stratification of ECC recurrence risk factors.我国早期结肠癌检出率逐年增加，明确早期结肠癌的定义对于病情评估、治疗决策及预后判断具有重要意义。尽管内镜切除已成为早期结肠癌治疗的可选方案，对肿瘤残留、高复发风险pT1期结肠癌，仍需及时外科干预以降低复发率和转移率。针对早期结肠癌外科手术的治疗时机、根治范围和肿瘤定位等关键问题，目前国内外尚未形成明确、统一的共识，腹腔镜手术技术的革新则有力推动了早期结肠癌微创外科的进步。外科手术后的随访应基于早期结肠癌的定义特征和复发风险因素，对早期结肠癌患者进行系统、规范和个体化的全程管理。.
