The recurrence rate, disease free interval, and adverse reaction after operation were observed. 观察术后复发率和无瘤间期及不良反应发生情况。
The favorable prognostic factors for survival include disease free interval > 2 years, no involvement of regional lymph nodes and the recurrence presented as a single nodule. 生存率预后良好的因素包括无病间期>2年,无区域淋巴结累及和复发灶表现为单结节。
Multivariate analysis showed that disease free interval, involvement of regional lymph nodes and the number of recurrent nodules were independent factors influencing the survival. 多因素分析发现无病间期长短和有无区域淋巴结累及是影响生存率的独立因素。
