Trimodal therapy is associated with higher overall survival than chemotherapy only in patients with metastatic inflammatory breast cancer
摘要
Systemic therapy is standard for metastatic inflammatory breast cancer (MIBC), but the role of locoregional therapy in survival remains unclear. The objective of this study was to compare overall survival (OS) between patients with MIBC who received trimodal therapy vs chemotherapy alone.
MethodsPatients diagnosed with MIBC between 2004 and 2021 were identified in the NCDB. The cohort was divided into those who received trimodal therapy vs chemotherapy only. Trimodal therapy included receipt of chemotherapy, surgery (modified radical or radical mastectomy), and radiation therapy. Overlap Propensity Score Weighted Cox proportional hazard models examined the association between treatment (chemotherapy versus trimodal therapy) and OS.
ResultsA total of 2872 patients with MIBC were included, of whom 403 (14.0%) underwent trimodal therapy and 2469 (86.0%) received chemotherapy alone. Median OS was longer with trimodality therapy than with chemotherapy alone (47.0 months vs 34.4 months, p < 0.001). Receiving trimodal therapy was associated with a 28% lower hazard of mortality compared to chemotherapy only (aHR: 0.72, 95% CI 0.62–0.84).
ConclusionsIn this NCDB cohort of patients with MIBC, receipt of trimodal therapy improved OS compared with chemotherapy only.
