Abstract

Objective: To evaluate surgical and oncological results of standard and extended lymph node dissection (D2 and D3) in patients with colon cancer.

Material and methods: We analyzed treatment outcomes in 74 patients with colon cancer stage T1-4aN0-2M0 who underwent right- and left-sided hemicolectomy, resection of sigmoid colon with standard and extended lymph node dissection (D2 and D3).

Results: Surgical approach and level of D3 lymph node dissection did not increase intra- and postoperative morbidity. Laparoscopic interventions were followed by significantly lower intraoperative blood loss and earlier gas discharge. Metastatic lesion of apical lymph nodes was observed in 5 out of 36 patients who underwent D3 lymph node dissection (13.8%), and metastases in regional lymph nodes rN1-2 were found in all these patients. Overall 5-year survival was 86%. Disease-free and overall 5-year survival were similar after D2 and D3 lymph node dissection.

Conclusion: D3 lymph node dissection is safe for colon cancer. Metastatic lesions of apical lymph nodes during D3 lymph node dissection were detected only in patients with lesions of regional lymph nodes (rN1-2). Disease-free and overall 5-year survival were similar after D2 and D3 lymph node dissection.

[结肠癌 D2 和 D3 淋巴结清扫术]。
摘要评估结肠癌患者接受标准和扩大淋巴结清扫术(D2和D3)的手术和肿瘤学效果:我们分析了74例T1-4aN0-2M0期结肠癌患者的治疗结果,这些患者接受了左右侧半结肠切除术、乙状结肠切除术以及标准和扩大淋巴结清扫术(D2和D3):结果:手术方式和 D3 淋巴结清扫水平不会增加术中和术后发病率。腹腔镜手术后,术中失血量明显减少,出院时间也更早。在接受D3淋巴结清扫术的36例患者中,有5例(13.8%)观察到顶端淋巴结转移病灶,所有这些患者均发现区域淋巴结rN1-2转移。5年总生存率为86%。D2和D3淋巴结清扫术后的无病生存率和5年总生存率相似:结论:D3淋巴结清扫术对结肠癌是安全的。结论:D3淋巴结清扫术对结肠癌是安全的,D3淋巴结清扫术仅在区域淋巴结(rN1-2)有病变的患者中发现根尖淋巴结转移病灶。D2和D3淋巴结清扫术后的无病生存率和5年总生存率相似。
