Feasibility Research For The Preservation Of Intercostobrachial Nerve In Axillary Lymphadenectomy For The Stage ⅠandⅡ Breast Cancer

Objectives To discuss the operability and clinical significance of protect intercostobrachial nerve(intercostobrachial nerve, ICBN) in modified radical mastectomy of breast cancer axillary lymph node dissection.Methods 85 cases of Ⅰ, Ⅱ breast cancer patients were retrospectively analysis with modified radical mastectomy of breast cancer axillary lymph node dissection; 43 cases with a view were retained the integrity of the ICBN selection of patients and 42 cases with a view were resected the ICBN selection of patients. Compared the two groups of patients of the operation time, bleeding volume, the number of surgery to remove lymph node dissection and 3 day, 1 month, 2 months, 6 months monitoring of affected scope of upper arm feeling obstacle, the emergence of pain after surgery.Results The operative time(t=0.103, P=0.918), blood loss(t =-0.414, P =0.681)and number of lymph node dissection(t =0.729, P =0.468)of the retained group were no significant difference compared with the resection group. The sensory disturbances in the two groups with incidence of abnormal side armpit and the inside of the upper arm after 3days had no significant difference(χ2=1.797, P=0.180). The upper area of the skin after paresthesia had a significant difference after 1 month(χ2=25.366, P =0. 000), 2 months(χ2 =24.199, P =0.000), 6 months(χ2 =21.756, P =0.000). The remission rate of the skin of postoperative patients with sensory disturbances of arm area after 1 、 2 and 6months were( χ2=90.022, P=0.000);( χ2=29.205, P=0.000);( χ2=75.862, P=0.000), and had a significant difference. The pain of the patients with arm area had a significant difference after 1 month(χ2 =23.292, P =0. 000), 2 months(χ2 =14.853, P=0.005), 6 months( χ2=12.275, P =0.006). The remission rate of the skin of postoperative patients with the pain of the patients with arm area had a significant difference after 6 months(χ2 =35.877, P =0.000).Conclusions Retaining the intercostobrachial nerve does not increase the difficult surgery in modified radical mastectomy of breast cancer for the stageⅠ, Ⅱbreast cancer.It could significantly reduce the incidence of the upper arm area of the skin paresthesia,pain. It can also improve the quality of the patients, positive in clinical application.
