Drug: lidocaine patch 5% (Lidoderm®, Endo Pharmaceuticals Inc.), 1 patch was applied topically to the affected site(s) for 12 hours each day.

Drug: placebo patch, 1 patch was applied topically to the affected site(s) for 12 hours each day.

1 patch was applied topically to the affected site(s) for 12 hours each day.

Lidoderm patch

Placebo patch

This trial is part of a larger, longitudinal study of symptoms that occur in the breast surgical scar area and/or ipsilateral arm following breast cancer surgery. Women who develop pain in the breast scar area or ipsilateral arm will be randomized to a placebo patch or a lidocaine patch that they will wear on a daily basis for 12 weeks. We hypothesize that women who wear the lidocaine patch will report a decrease in pain and decreased interference with function compared to women who wear the placebo patch.

Symptom Management After Breast Cancer Surgery

A Randomized, Double-Blind, Placebo-Controlled Trial (RDBPCT) of the Effectiveness of the Lidocaine Patch in the Management of Neuropathic Pain After Breast Cancer Surgery

Patients scored their pain intensity in the breast and/or ipsilateral arm using a 0 to 10 numeric rating scale, ranging from no pain (0) to worst pain imaginable (10). The change in pain intensity was calculated from two time points as the later time point (12 weeks) minus the earlier time point (Baseline).

Worst pain intensity

Dr. Christine Miaskowski, PI

This study attempted to evaluate changes in average pain intensity following breast cancer surgery. However, since none of the patients in the lidocaine group completed the 12 week trial, the outcomes of this study cannot be evaluated.
