食管癌淋巴结转移相关研究

Lymph Node Metastases from Carcinoma of the Thoracic Esophagus and Gastric Cardia: A Random Sampling Report

  • 摘要: 淋巴结是食管癌转移的主要部位,其淋巴引流区域涉及颈部、胸部和腹部,对其检测和监测有着重要的临床意义。目前科技不断发展,各种检查手段不断应用于临床,有利于对病情进行客观准确的评价。另外,食管癌的淋巴结转移受肿瘤分化程度、浸润深度、肿瘤长度等多种因素的共同影响,其中部分因素还存在一些不同的观点或认识。因此,准确的术前淋巴结(N)分期和术中评估为临床淋巴结清扫范围提供了重要指导。由于病理诊断技术的进步,对淋巴结微转移的认识和检测使N分期的准确率得到进一步提高。多数研究认为食管癌有淋巴结转移明显影响着预后,然而新的国际TNM分期中仅将淋巴结转移状况分为N1和N0两种状态,而未将淋巴结转移部位、数量及频度等考虑在内。根治性手术仍是治疗食管癌主要手段之一,食管切除及淋巴结清扫术的开展明显提高了食管癌病人生存率,但对于食管癌淋巴结清扫范围的界定目前尚缺乏统一的认识,且术后并发症也随手术范围的扩大而增加。随着研究的不断深入,各种报道不断地对食管癌现有N分期进行再认识和补充,多角度地阐明淋巴结转移所产生的不良影响,这将有助于我们更加全面和深入地认识和理解N分期,进而指导临床选择个体化的手术方式。

     

    Abstract: Objective : To observe the status of lymphatic metastases from carcinoma of the esophagus and gastriccardia and to analyze the factors correlated with lymph node metastases. Methods : Clinical data from 1,526patients with carcinoma of the thoracic esophagus and gastric cardia seen in our hospital between January1996 and December 2004 were analyzed. Factors including the age, tumor location, tumor diameter, patholog-ical classification, the depth of tumor invasion, vascular tumor embolus, the involvement of other organs, andthe status of tumor residues were stratified and analyzed with SPSS13.0 software. Results : Carcinoma of theupper thoracic esophagus mainly metastasized to thoracic and cervical lymph nodes; carcinoma of the mid-dle-third thoracic esophagus metastasized bidirectionally; and carcinoma of the lower-third thoracic esopha-gus mainly metastasized to the lymph nodes of the lateral esophagus, lateral cardia and gastric artery. Thelymph node metastasis rate of lower-third esophageal cancer was higher than that of upper and middle-thirdesophageal cancer (P<0.0125). Compared with thoracic esophageal cancer, carcinoma of the gastric cardiachad a higher rate of metastasis to lymph nodes in the abdominal cavity, lateral cardia and gastric artery (P<0.05). No statistical significance was found in the metastasis to the lateral esophageal lymph nodes betweencarcinoma of the gastric cardia and thoracic esophageal carcinoma (P>0.05). Results of Multiple Factors Lo-gistic Regression Analysis showed that tumor diameter, the depth of tumor invasion, vascular tumor embolusand the status of carcinoma residues influenced the status of lymphatic metastasis. Conclusion : Upper tho-racic esophageal carcinoma mainly metastasizes to cervical and thoracic lymph nodes; middle-third thoracicesophageal carcinoma tends to extend bidirectionally; lower-third thoracic esophageal carcinoma mainlymetastasizes to abdominal and thoracic lymph nodes; and carcinoma of the gastric cardia mainly metasta-sizes to abdominal lymph nodes and lateral esophageal lymph nodes. Tumor diameter, the depth of tumor in-vasion, vascular tumor embolus and the status of tumor residues are correlated to lymphatic metastasis.
