Single institutional experience of radiation therapy for angiosarcoma of the scalp without cervical lymph node metastases: Impact of concurrent chemoradiation with maintenance chemotherapy using taxanes on patient prognosis

Research output: Contribution to journalArticle

Abstract

Cutaneous angiosarcoma is a rare aggressive malignant tumor. Concurrent chemoradiation (CCRT) with maintenance chemotherapy using taxanes is one of the primary treatments. The aim of the present study was to retrospectively analyze the efficacy of CCRT with maintenance chemotherapy using taxanes in localized angiosarcoma of the scalp without cervical lymph node metastases. A total of 19 patients treated with radiation therapy for localized angiosarcomas of the scalp without cervical lymph node metastases were enrolled. The overall survival (OS), progression-free survival (PFS), and local control (LC) rates were calculated using Kaplan-Meier analysis. Univariate analyses were performed for various potential prognostic factors for OS, PFS, and LC. The median radiation dose was 70 Gy (range, 60-70 Gy), and the fractional dose was 2 Gy. Radiation therapy alone, radiation therapy + interleukin-2, surgery + CCRT with maintenance chemotherapy, CCRT with maintenance chemotherapy, and CCRT without maintenance chemotherapy were administered to 2, 4, 2, 9 and 2 patients, respectively. The 1- and 3-year OS, PFS, and LC rates were 88 and 52%, 47 and 33%, and 74 and 56%, respectively. CCRT with maintenance chemotherapy and surgery were significant prognostic factors for PFS (P=0.036 and 0.025, respectively). Therefore, CCRT with maintenance chemotherapy using taxanes might be effective in treating localized angiosarcomas of the scalp without cervical lymph node metastases.
