Abstract
Background
Oncoplastic surgery (OPS) replaces lumpectomy as standard technique in breast conserving
surgery (BCS). OPS has shown to give good cosmetic results, but is it as safe as standard
lumpectomy? We conducted a retrospective cohort study to determine postoperative complications,
resection margins and re-excision rates for OPS compared to standard lumpectomy.
Methods
Based on data from the ‘Netherlands Cancer Registry’ and medical records we scored
patient, treatment and follow-up related variables. All consecutive patients, with
an initially breast conserving operation for primary breast cancer, performed between
January 2010 and December 2014 in a dedicated breast center were eligible. Breast
surgeons performed the operations. Invasive and in situ tumors were included. Postoperative
complications within 30 days after surgery and the need for additional treatment were
classified using the Clavien Dindo classification. Involved margin rates and subsequent
re-excision were compared.
Results
We included 828 women with 842 breast cancers, who had a standard lumpectomy (62.7%)
or oncoplastic resection (37.3%). OPS was performed more often for larger tumors (17.5 mm
vs 13.6 mm, p = 0.002) and for tumors in the caudal half of the breast (33.1% vs 16.9%,
p < 0.001). There was no significant difference in postoperative complications. Positive
surgical margins were similar (OPS 22.6%, lumpectomy 18.2%, p = 0.119), as were re-excision
rates (p = 0.337).
Conclusion
Oncoplastic breast surgery can be safely applied in larger tumors, resulting in comparable
postoperative complications, resection margins and re-excision rates compared to standard
lumpectomy.
