Objective:To investigate the clinical value of preserving intercostobrachial nerve( ICBN) in modified radical mastectomy. Methods:Eighty-three breast cancer patients treated with modified radical mastectomy were divided into the observation group(41 cases treated with preserving ICBN) and control group(42 cases treated without preserving ICBN). All patients were followed up for 3 months to 3 years. The operation time,number of dissecting lymph nodes,indicence rate of sensory dysfunction,limb lymphedema rate and local recurrence rate between two groups were compared. Results:The mean operation time and number of dissecting lymph nodes in observation group were(113. 56 ± 5. 78) min and(12. 28 ± 2. 19),respectively. The mean operation time and number of dissecting lymph nodes in control group were(110. 17 ± 5. 41) min and(12. 83 ± 2. 13),respectively. The differences of the operation time, number of dissecting lymph nodes and limb lymphedema rate between two groups were not statistically significant(P >0. 05). The postoperative sensory dysfunction rates in observation group and control group were 21. 95% and 66. 67%,respectivly,the difference of which between two groups was statistically significant(P0.0.5).观察组术后皮肤感觉异常发生率为21.95%,明显低于对照组的66.67%(P<0.05).2组患者术后随访期间均未发现肿瘤局部复发.结论:乳腺癌改良根治术中清扫腋窝淋巴结时,予以保留ICBN可明显减少术后患侧胸壁和上臂内侧感觉异常的发生率,值得推广.
