How Does Oncoplastic Surgery Compare with Standard Partial Mastectomy? A Systematic Review of Patient-Reported Outcomes

Abstract

Many breast-conserving surgical options exist for patients with breast cancer. Surgical choices can have lasting effects on a patient's life, so patient satisfaction is important to assess. Patient-reported outcome measures provide important tools when evaluating surgical modalities. This systematic review aimed to evaluate how patients describe breast-conserving surgical choices in standard partial mastectomy and oncoplastic surgery options. A Preferred Reporting Items for Systematic Reviews and Meta-Analyses search was performed in PubMed for studies discussing standard partial mastectomy or oncoplastic surgery and measurement of preoperative and postoperative patient-reported outcomes using the BREAST-Q or other validated patient-reported outcome measures. Oncoplastic surgery was categorized as volume displacement or volume replacement. Articles in languages other than English, not involving partial mastectomy or oncoplastic surgery, or not measuring patient-reported outcomes were excluded. Weighted proportions were generated and analyzed with a Welch t test. Of 390 articles, 43 met inclusion criteria, and 8784 patients were included in a pooled database. Although standard partial mastectomy scored well, oncoplastic surgery performed significantly better than partial mastectomy in all postoperative BREAST-Q categories: satisfaction with breasts (74.3 versus 65.7), psychosocial well-being (81.3 versus 78.0), sexual well-being (61.6 versus 54.9), and satisfaction with outcome (85.4 versus 62.2). Level 2 volume displacement surgery had the most favorable scores. Breast-conserving surgical choices that include a variety of oncoplastic surgery and partial mastectomy methods all score well in patient-reported outcome measures, with oncoplastic surgery significantly preferred over partial mastectomy. Oncoplastic surgery should be considered in all cases, and the appropriate breast-conserving surgical choice should depend on the patient's tumor presentation and anatomy.
