ONCOPLASTIC PATTERNS IN THE CONSERVATIVE TREATMENT OF BREAST CANCER AND HIGH RISK LESIONS

Abstract

Objective: To demonstrate the effectiveness of oncoplastic techniques by the breast surgeon performing the lumpectomy with satisfactory cosmetic outcomes, at the Centro Clínico Familia, Puerto Ordaz. Patients and method: A prospective study in patients with breast cancer and risk lesions, between September 2009 -December 2011, in whom conventional lumpectomy would cause cosmetic defect and this was determined by the size, location, and relation tumor/breast volume, multicentric or bilateral lesion. Results: Eleven patients were operated. Eight with diagnosed breast cancer. Invasive carcinoma: seven patients (63.7%), lobular in situ carcinoma: one patient (9%) and with
atypical ductal hyperplasia: three patients (28.1%). The oncoplastic technique more used was the vertical mamoplasty with inferior single branch pedicle: six patients (54.5%). The vertical mammoplasty with superior branch single pedicle and Grisotti´s technique: two patients (18%) respectively. periareolar mamoplasty: one case (9%). Sentinel lymph node biopsy was performed on five patients without complications due to the subareolar injection of patent blue. The cosmetic results were satisfactory. One patient presented a little asymmetry of height of complex areola - nipple and another patient presented a hematoma that was drained ambulatory. Conclusion: Oncoplastic techniques are effective surgical techniques in the conservative treatment of breast cancer and allow extensive resection with excellent cosmetic results. These procedures can be performed by the breast surgeon without formal training in plastic surgery, but based on a thorough planning
of techniques without excessive complexity.
