Oncoplastic Breast Surgery (OBS)

Rodrigo Arrangoiz MS, MD, FACS, FSSO
  • Oncoplastic breast surgery (OBS):
    • Combines principles of oncology and plastic surgery:
      • Toward achieving sound oncological and aesthetically pleasant results for breast tumors amenable to segmental mastectomies in patients with a favorable tumor to breast volume
  • OBS expands the indications for breast conservation:
    • Allowing the resection of much larger tumors, and is now an option for the surgical treatment of tumors larger than 4 cm and locally advanced cancers especially in large-breasted patients
    • When compared to conventional breast-conserving surgery (BCS):
      • OBS commonly results in higher specimen resection volumes and lower re-excision rates 
    • OBS does not eliminate or change the need for adjuvant therapies; most, if not all, patients undergoing segmental mastectomy for invasive breast cancers will benefit from adjuvant radiation therapy
    • OBS training is widely accepted as a prerequisite for performing these surgeries and should be represented in any multidisciplinary team, treating breast cancer and offering OBS: 
      • While no definitive test exists to assess aesthetic results and compare these between OBS and BCS for matched defects, most studies report favorable aesthetic results following OPS, in the majority of patients
