Preservation of the intercostobrachial nerve during axillary dissection for breast cancer

Preservation of the intercostobrachial nerve during axillary dissection in 50 patients with stage I breast cancer resulted in a significant improvement in sensory function compared with the standard dissection in which the nerve is routinely sacrificed. No local recurrence was found during the 3 to 5 year follow-up period. This modification is worthwhile in patients with axillas that are clinically negative for cancer.
