The Complex Management of the Breast Angiosarcoma: A Retrospective Study

Abstract

<b><i>Background/Aim:</i></b> Breast angiosarcoma is a rare and aggressive disease with a poor prognosis. Two subtypes have been identified: primary angiosarcoma (PBA) and secondary breast angiosarcoma (SBA). In this retrospective analysis, we describe and compare our institute experience with the data existing in the literature. <b><i>Materials and Methods:</i></b> We included in our analysis 29 patients who received a diagnosis of PBA or SBA between 2006 and 2019. <b><i>Results:</i></b> All patients received surgery as frontline treatment, but only 6 patients underwent to adjuvant treatment. Neoadjuvant chemotherapy was administered 2 patients. The preferred chemotherapeutic regimen was taxanes with or without gemcitabine and associated with anthracyclines. A lower median RFS and OS were reported in patients with PBA compared to those with SBA, but the difference observed was not statistically significant. Patients with PBA had a lower median age at the diagnosis (38 vs. 75). <b><i>Conclusion:</i></b> In our analysis, we have shown a lower median RFS and OS in patients with PBA compared with those with SBA, and a significantly younger age at diagnosis in patients affected by PBA.
