CONSERVATIVE SALVAGE SURGERY FOR SECOND PRIMARY MINIMALLY INVASIVE BREAST CARCINOMA OCCURRING AFTER BREAST CONSERVATION SURGERY-REPORT OF THE THREE CASES-

Abstract

We report three cases of second primary carcinoma detected after breast conservation surgery that were successfully treated by conservative salvage surgery. Case 1: A 46-year-old woman had undergone right quadrantectomy (Bq) with axillary dissection (Ax) for primary papillotubular carcinoma located in section C at the age of 44 years. She underwent wide excision (Bp) for the second primary papillotubular carcinoma in right section A. Case 2: A 49-year-old woman had undergone Bq+Ax for primary papillotubular carcinoma located in left section C at the age of 44 years. She underwent Bq+Ax for the second primary tubular carcinoma in right section A. Case 3: A 46-year-old woman had undergone Bq+Ax for non-invasive ductal carcinoma located in left section AB at the age of 41 years. She underwent Bq for the second primary papillotubular carcinoma in left section A. None of the three primary carcinomas had axillary lymph node metastasis, and radiation therapy was not performed in any of the three cases after the initial surgery with negative margins. All of the second primary carcinomas were nonpalpable, low-echoic masses measuring less than 1.0cm. We believe that ultrasonography is extremely useful as a modality leading to verify small local recurrence or second primary cancer after breast conservation treatment.
