There has been a gradual shift away from radical surgery towards conservation treatment for breast cancer. The pectoralis minor muscle is increasingly preserved in women undergoing axillary clearance as part of either breast conservation or mastectomy.
A retrospective study was conducted to determine the axillary node count in 578 patients who underwent axillary clearance, 276 with removal of pectoralis minor and 302 who had the muscle preserved.
The mean number of nodes excised in the group who had pectoralis minor excised was 25.5 (range 8-50) compared with 24.5 (range 9-68) in the preservation group.
For the majority of patients with operable breast cancer, retention of the pectoralis minor muscle is not associated with understaging or undertreatment of the axilla.
乳腺癌的治疗已逐渐从根治性手术转向保守治疗。在接受腋窝清扫术的女性中，无论是保乳手术还是乳房切除术，胸小肌越来越多地被保留。
进行一项回顾性研究，以确定578例行腋窝清扫术患者的腋窝淋巴结数量，其中276例切除胸小肌，302例保留该肌肉。
切除胸小肌组切除的平均淋巴结数为25.5个（范围8 - 50个），而保留组为24.5个（范围9 - 68个）。
对于大多数可手术乳腺癌患者，保留胸小肌与腋窝分期不足或治疗不足无关。
