摘要:
Objective To evaluate the significance of different clinicopathologic features on prognosis of patients with squamous cell carcinoma of vulva. Methods We retrospectively analyzed the prognostic relevance of different clinicopathological variables of 201 patients with squamous cell carcinoma of vulva treated in Cancer Hospital, Chinese Academy of Medical Sciences. The data including age, initial symptoms, stage, location, tumor size, histological grade, number and size of metastatic lymph nodes, treatment mode, and presence of leukoplakia vulva was used to evaluate the prognosis of vulvar squamous cell carcinoma. Results The median age of onset was 62.0 years old, with 74 patients in stage Ⅰ, 27 in stage Ⅱ, 55 in stage Ⅲ and 9 in stage Ⅳ. The median progression?free survival was 90.0 months. The 5?year progression?free survival rate of the total patients was 55.5%, while the 10?year progression?free survival rate was 48.5%. Univariate analysis showed statistically significant prognostic parameters included clinical stage, number of metastatic lymph nodes, tumor size and treatment mode ( all P<0.001 ). Multivariate analysis showed that number of metastatic lymph nodes ( P<0.05 ) was an independent prognostic factor for progression?free survival. Conclusion The study illustrates that number of metastatic lymph nodes represents important independent factor for progression?free survival of patients with vulvar squamous cell carcinoma.%目的 分析外阴鳞癌的临床病理特征,探讨外阴鳞癌的预后影响因素.方法 收集中国医学科学院肿瘤医院初治的201例外阴鳞癌患者的临床病理资料,包括发病年龄、首发症状、是否存在外阴白斑、发病部位、病灶大小、组织分化程度、治疗方式、手术分期、有无淋巴结转移、转移淋巴结数目及大小、复发时间、生存现状,进行回顾性研究.预后影响因素的单因素及多因素分析采用Cox回归模型.结果 全组患者的中位发病年龄为62.0岁,Ⅰ期74例,Ⅱ期27例,Ⅲ期55例,Ⅳ期9例.中位无进展生存时间为90.0个月,5年无进展生存率为55.5%,10年无进展生存率为48.5%.单因素Cox回归分析显示,病灶大小、国际妇产科联盟( FIGO)分期、淋巴结转移数、治疗方式与外阴鳞癌患者的无进展生存有关(均P<0.001).淋巴结转移数为外阴鳞癌患者无进展生存的独立影响因素(P<0.05).结论 淋巴结转移数是外阴鳞癌患者无进展生存的独立影响因素.
