Is Proton Beam Radiotherapy Worthwhile in the Management of Angiosarcoma of the Scalp?

In inoperable patients, the management of angiosarcoma of the scalp is challenging. Due to intrinsic, dosimetric and radiobiological properties, proton beam radiotherapy may be an effective and safe option to offer to these difficult-to-cure patients. Here, we report a case of angiosarcoma of the scalp treated successfully with proton beam radiotherapy. Angiosarcoma is a rare malignancy concerning around 2% of soft-tissue sarcomas and 5% of cutaneous soft-tissue sarcomas. Cutaneous angiosarcomas can occur in any part of the body, but the head and neck region is a common primary site and the scalp is a frequent site in elderly patients.
