摘要目的 探讨乳癌手术腋窝淋巴结清扫时保留肋间臂神经(ICBN)的临床价值.方法 对146例Ⅰ、Ⅱ、Ⅲa期乳癌患者行改良根治术的临床资料进行分析.将其随机分为两组:保留组(67例)行腋窝淋巴结清扫术时保留ICBN,对照组(79例)行腋窝清扫时常规切除ICBN,比较两组在手术时间、淋巴结清扫数量及术后上臂内侧感觉异常等情况.结果 保留组及对照组术后1、3、6个月患侧上臂内侧感觉障碍发生率分别为17.9%、74.9%(P＜0.01);11.9%、60.7%(P＜0.01);7.4%、59.5%(P＜0.01),差异有统计学意义,手术时间及淋巴结清扫数无明显差异,术后8个月～5年随访无局部复发.结论 对Ⅰ、Ⅱ、Ⅲa期乳癌患者在行腋窝淋巴结清扫时保留ICBN可明显减少术后患侧上臂内侧感觉障碍,提高生活质量,不影响局部复发率.

abstractsObjective To study the clinical value of preserving intercostobrachial nerve(ICBN) during axillary lymph node dissection.Methods The clinical data of 146 cases of operated breast cancer of stage Ⅰ、Ⅱ、Ⅲa were analyzed.All cases were divided into twe groups randomly:preserved group(n=67) preserved ICBN in axillary lymph node dissection operation;control group(n=79) resected ICBN regulary in the operations.The number of lymph node dissection and the incidence of abnormal sense on the skin of inside upper arm were compared between groups.Results In one month,three months and six months followed up:the incidence of ahnormal sense on the skin of inside upper arm was 17.9%,11.9%,7.4% in preserved group,which was lower than that (74.9%,60.7%,59.5%) in control group significantly (P＜0.01).The diflrence between the two groups was significant.No local recurrence was occurred after opreations from eight months to five years examined.It was none difference that period of operation and the number of lymph node dissection between the groups.Conclusions Preserving ICBN in axillary lymph node dissection for breast cancer of stage Ⅰ、Ⅱ、Ⅲa could decrease the incidence of abnormal sence on the skin of inside upper arm.It eouldnt increase the incidence of local recurrence.It can improve the life quality of the patients after operations.
