BackgroundPostmastectomy pain syndrome (PMPS) has been reported following procedures involving complete lymph node dissection (CLND). Since the triggering event is probably related to nerve injury, sentinel lymph node dissection (SLND) should decrease the incidence of PMPS. The purpose of this report is to determine the impact of SLND on the number of patients referred to the pain clinic for PMPS treatment.MethodsThe records of all breast surgical patients with a diagnosis of PMPS referred to the Moffitt Cancer Center pain clinic were reviewed. The criterion for diagnosis of PMPS was a history of postoperative pain in the upper anterior chest wall, upper extremity, axilla, and/or shoulder in the absence of recurrent disease.ResultsA total of 55 patients with a diagnosis of PMPS were seen in the pain clinic since 1991. Treatments included local anesthetics/corticosteroid injection, stellate ganglion block, and tricyclic antidepressants. A decrease from 15 patients in 1991 to 3 in 1998 was observed. All but one of the 55 patients with PMPS had CLND, and none referred to the pain clinic had undergone SLND.ConclusionsPMPS is a complication of CLND. The increased use of SLND in our center has reduced the number of referrals to the pain clinic for treatment of PMPS. This benefit of SLND reduces suffering in the postoperative breast patient.
