瘢痕疙瘩手术加放射治疗复发因素分析

Factors related to recurrence of keloid after postoperative radiotherapy

目的分析瘢痕疙瘩术后放射治疗的疗效。方法回顾分析术后放射治疗的83例瘢痕疙瘩患者的复发情况。采用SAS6.12软件,以瘢痕疙瘩术后放射治疗后的复发与否为应变量,性别、年龄、病变部位、病变面积、开始照射时间、放射治疗方法为自变量,对其进行Logistic逐步回归分析。结果瘢痕疙瘩术后放射治疗复发与病变面积和开始照射时间相关,而与性别、年龄、病变部位等无关。结论采用几种疗效肯定的放射治疗方法治疗术后的瘢痕疙瘩,其复发与病变大小和开始照射时间相关。

Objective To report on the outcome of postoperative radiotherapy of keloid. Methods The recurrence rate of 83 patients with keloid which had been treated by surgery and postoperative radiotherapy were retrospectively reviewed with χ 2 check and stepsise LOGISTIC regression using software SAS 6.12. Results Recurrence of keloid after postoperative radiotherapy was correlate with size of lesion and interval after operation but not with sek,age or site of lesion. Conclusions With any an authentic method of postoperative radiotherapy,recurrence of keloid would only be correlated with size of lesion and interval after operation.
