Abstract

PURPOSE
Sensory changes in the upper limb are complications of a mastectomy with immediate breast reconstruction with the treatment of breast cancer. The purpose of this study is to clarify whether immediate breast reconstruction worsens the sensory changes. METHODS: From March 2004 to December 2005, 20 patients who had a mastectomy with immediate breast reconstruction(reconstruction group) were compared with 23 patients who had a mastectomy alone(control group). All patients had stage I or II breast cancer. The sensory changes were assessed in a blind manner by one examiner that used light touch sensation, static two-point discrimination, pain, vibration, hot and cold temperature perception. The sensory changes were identified along the sensory dermatome for diagnosing the damaged nerves. The following factors and their relationship with the sensory changes were analyzed:age, complications, and the mastectomy method.
RESULTS
There was no statistical difference in the static two-point discrimination, pain, vibration, hot and cold temperature perception between the two groups. However, the ability to recognize light touch was significantly better(p=0.045) in the reconstruction group than in the control group. The main site of sensory change was the proximal and medial portion of the upper limb in both groups. At these sites, the mean value of Semmes-Weinstein monofilament was 1.01g/ mm2(reconstruction group 0.82, control group 1.17) and 2-point discrimination was 51.74(converted to perfect score of 100; reconstruction group 42.50, control group 59.78). The total rate of early complications was found to be significantly lower(p=0.006) in the reconstruction group than in the control group.
CONCLUSION
These findings suggest that an immediate breast reconstructive procedure following a mastectomy is as safe as or safer than a mastectomy alone with respect to postoperative sensory changes of the ipsilateral upper limb.
