Preservation of the Intercostobrachial Nerve during Axillary Dissection for Breast Cancer at the Surgical Oncology Unit of Cancer Department of Dakar University
The intercostobrachial nerve
(ICBN) is responsible for the sensory innervation of a part of the inner side of the arm.
Injury of the intercostobrachial nerve is a
complication of axillary dissection during lymph node dissection.Objective: This study aimed to determine the effect of
preservation of the intercostobrachial
nerve on postoperative sensory disturbances. Methods: This is a prospective, single-center study which was carried out in 90 patients followed
in the oncology department of the Aristide Le Dantec hospital in Dakar,
suffering from breast cancer and having
undergone breast surgery associated with axillary dissection, for a period of 6 months. The patients
were divided into two groups depending on whether the intercostobrachial
nerve (ICBN) was preserved or not. The two
groups were compared in terms of the incidence of sensory disturbances. Results: Sixty patients without nerve preservation and 30 patients with nerve
preservation were included in the study, i.e.,
90 patients in total. ICBN was injured in 60
patients of which 41 patients (83.7%) developed numbness in the inner
arm. While in the preserved group, only 8 patients suffered from numbness
(16.3%) with a significant P value of 0.002; however, for other variables
such as the incidence of neuropathic pain and hypoesthesia-like sensory
