摘要:
目的 探讨混合型早期胃癌淋巴结转移的规律以及淋巴结转移对远期预后的影响。 方法 选取2014年1月到2016年1月上海交通大学医学院附属苏州九龙医院收治的87例混合型早期胃癌患者作为研究对象,均接受手术治疗。对患者进行随访,观察总生存时间(OS),分析混合型早期胃癌淋巴结转移的规律以及淋巴结转移对OS影响。 结果 87例混合型早期胃癌患者中,20例淋巴结转移,67例未转移,淋巴结转移率为22.99%。淋巴结转移患者肿瘤直径、淋巴管受累率、黏膜下层比例、溃疡型比例高于非淋巴结转移患者,差异有统计学意义(P < 0.05)。Logistic分析结果显示,浸润深度、淋巴管受累、肿瘤大小是混合型组淋巴结转移的影响因素(P < 0.05)。随访时间48~72个月,平均随访时间(62.8±4.8)个月,失访6例,患者3 a生存率为90.1%,5 a生存率为86.4%。Kaplan-Meier法并Log-rank检验显示,混合型组淋巴结转移患者OS短于非淋巴结转移患者(P < 0.05)。Cox分析结果显示,淋巴管受累、淋巴结转移、血管受累、浸润深度是混合型早期胃癌患者生存的独立影响因素(P < 0.05)。 结论 混合型早期胃癌淋巴结转移率高,肿瘤直径大、浸润黏膜下层、淋巴管受累患者淋巴结转移风险增高,且淋巴结转移患者预后差,死亡率高。 Abstract:Objective To investigate the regularity of lymph node metastasis in mixed early gastric cancer and its effect on long-term prognosis. Methods Eighty-seven patients with mixed early gastric cancer admitted to Suzhou Jiulong Hospital, Shanghai Jiaotong University School of Medicine from January 2014 to January 2016 were selected as the research objects. All patients received surgery. The patients were followed up to observe the overall survival time (OS) and the regularity of lymph node metastasis in early gastric cancer and the effect of lymph node metastasis on OS were analyzed. Results Among the 87 patients with mixed early gastric cancer, 20 had lymph node metastasis and 67 had no metastasis. The lymph node metastasis rate was 22.99%. Patients with lymph node metastasis had higher tumor diameter, lymphatic involvement rate, submucosal ratio, and ulcer type than those with non-lymph node metastasis, the differences were statistically significant (P < 0.05). Logistic analysis showed that the depth of infiltration, lymphatic involvement, and tumor size were the influencing factors of lymph node metastasis in Mixed group (P < 0.05). The follow-up time was 48~72 months. The average follow-up time was (62.8 ± 4.8) months. Six patients were lost to follow-up. The 3-year survival rate was 90.1%, and the 5-year survival rate was 86.4%. Kaplan-Meier method and Log-rank test showed that the survival time of patients with lymph node metastasis was shorter than that of patients with non-lymph node metastasis (P < 0.05). Cox analysis showed that lymphatic involvement, lymph node metastasis, vascular involvement, and depth of invasion were independent factors affecting the survival of patients with mixed early gastric cancer (P < 0.05). Conclusions Lymph node metastasis rate of mixed early gastric cancer is high. Patients with large tumor diameter, submucosa, and lymphatic involvement have an increased risk of lymph node metastasis. Patients with lymph node metastasis have a poor prognosis and a high mortality rate. -
