Background:
Oncoplastic breast surgery refers to a wide range of techniques with a parallel goal of safely removing all malignant breast tissue while achieving the best possible esthetic outcome. We report the results of our oncoplastic breast operations from 2005 to 2007.
Methods:
Ninety selected breast cancer patients were treated with a variety of oncoplastic operations. The patients were prospectively monitored. Radiotherapy and systemic adjuvant treatment were given according to national guidelines.
Results:
Fifteen patients had an immediate surgical complication, of which 8 required a reoperation. Eleven patients had an inadequate surgical margin and required a completion mastectomy. During a median follow-up of 26 months no local or regional recurrences were noticed. Three patients developed distant metastases.
Conclusions:
Oncoplastic breast surgery offers tools for breast conservation in patients otherwise destined for mastectomy or poor esthetic outcome. Despite the high proportion of patients in this series with large-volume ductal carcinoma in situ (DCIS) or extensive intraductal component, the use of oncoplastic techniques achieved negative margins with acceptable cosmetic results in the majority (84%) of patients.
