Abstract

INTRODUCTION: Extreme oncoplastic breast-conserving surgery (eOBCS) describes the application of OBCS to patients who would otherwise need a mastectomy, and its safety has been previously described.

OBJECTIVE: We aimed to compare the costs of eOBCS and mastectomy.

METHODS: We reviewed our institutional database to identify breast cancer patients treated surgically from 2018 to 2023. We included patients with a large disease span (≥5 cm) and multifocal/multicentric disease. Patients were grouped by their surgical approach, i.e. eOBCS or mastectomy. The direct costs of care were determined and compared; however, indirect costs were not included.

RESULTS: Eighty-six patients met the inclusion criteria, 10 (11.6%) of whom underwent mastectomy and 76 (88.4%) who underwent eOBCS. Six mastectomy patients (60%) had reconstruction and 6 (60%) underwent external beam radiation therapy (EBRT). Reconstructions were completed in a staged fashion, and the mean cost of the index operation (mastectomy and tissue expander) was $17,816. These patients had one to three subsequent surgeries to complete their reconstruction, at a mean cost of $45,904. The mean cost of EBRT was $5542. Thirty-four eOBCS patients (44.7%) underwent 44 margin re-excisions, including 6 (7.9%) who underwent mastectomy. Sixty (78.9%) of the eOBCS patients had EBRT. The mean cost of their index operation was $6345; the mean cost of a re-excision was $3615; the mean cost of their mastectomies with reconstruction was $49,400; and the mean cost of EBRT was $6807. The cost of care for eOBCS patients remained lower than that for mastectomy patients, i.e. $17,318 versus $57,416.

CONCLUSION: eOBCS is associated with a lower cost than mastectomy and had a low conversion rate to mastectomy.
