Background Management of locally advanced colon cancer (LACC) is challenging. Surgery is the mainstay of the treatment, yet its outcomes remain unclear, especially in the setting of multivisceral resections. The aim of the study was to examine the outcomes of standard and multivisceral colectomy in patients with LACC. Patients and methods Patients demographics, clinical and perioperative data of patients operated within study period 2004-2018 were collected. LACC was defined as stage T4 colon cancer including tumor invasion either through the visceral peritoneum or to the adjacent organs/structures. Accordingly, either standard or multivisceral colectomy (SC and MVC) was performed. Results Two hundred and three patients underwent colectomy for LACC. Of those, 112 had SC (55.2%) and 91 (44.8%) had MVC. Severe morbidity and mortality rates were 5.9% and 2.5%, respectively. MVC was associated with an increased blood loss (200 ml vs. 100 ml, p = 0.01), blood transfusion (22% vs. 8.9%, p = 0.01), longer operative time (180 minutes vs. 140 minutes, p < 0.01) and postoperative hospital stay (11 days vs. 10 days, p < 0.01) compared with SC. The complication-associated parameters were similar. Male gender, presence of ≥ 3 comorbidities, tumor location in the left colon and perioperative blood transfusion were associated with complications in the univariable analysis. In the multivariable model, the presence of ≥ 3 comorbidities was the only independent predictor of complications. Conclusions Colectomy with or without multivisceral resection is a safe procedure in LACC. In experienced hands, the postoperative outcomes are similar for SC and MVC. Given the complexity of the latter, these procedures should be reserved to qualified expert centers.
背景 局部晚期结肠癌(LACC)的治疗颇具挑战性。手术是治疗的主要手段,但治疗效果仍不明确,特别是在进行多脏器联合切除时。本研究旨在探讨 LACC 患者行标准结直肠切除术与多脏器联合切除术的治疗效果。
方法 收集 2004 年至 2018 年期间接受手术治疗的 LACC 患者的人口统计学、临床和围手术期数据。LACC 定义为 T4 期结肠癌,肿瘤侵犯内脏腹膜或邻近器官/结构。因此,行标准结直肠切除术(SC)或多脏器联合切除术(SC 和 MVC)。
结果 203 例患者因 LACC 行结直肠切除术。其中 112 例行 SC(55.2%),91 例行 MVC(44.8%)。严重并发症发生率和死亡率分别为 5.9%和 2.5%。与 SC 相比,MVC 术中出血量(200ml vs. 100ml,p=0.01)、输血率(22% vs. 8.9%,p=0.01)、手术时间(180min vs. 140min,p<0.01)和术后住院时间(11d vs. 10d,p<0.01)更长。并发症相关参数相似。单因素分析显示,男性、合并≥3 种合并症、肿瘤位于左半结肠和围手术期输血与并发症相关。多因素模型分析显示,合并≥3 种合并症是并发症的唯一独立预测因素。
结论 在 LACC 患者中,行标准结直肠切除术或多脏器联合切除术均是安全的。在有经验的术者手中,SC 和 MVC 的术后效果相似。鉴于后者的复杂性,这些手术应保留给有资质的专家中心。
