Solitary fibrous tumor/hemangiopericytoma (SFT/HPC) is a rare tumor derived from mesenchymal tissue. Although standard chemotherapy for SHT/HPC has not been established, temozolomide plus bevacizumab (TMZ+Bev) therapy for SFT/HPC has been reported. The effectiveness and safety of TMZ+Bev (temozolomide 150 mg/m2 orally on days 1-7 and days 15-21 and bevacizumab 5 mg/kg intravenously on day 8 and day 22 on a 28-day cycle), which was administered from December 2013 until April 2019 to four patients with SFT/HPC, were retrospectively analyzed. ⋯ All patients experienced Grade 3 or higher lymphopenia, and three had Grade 3 or higher leukopenia and neutropenia. One patient subsequently received doxorubicin; another, pazopanib. TMZ+Bev therapy for SFT/HPC is safe and effective for maintaining long-term SD.
