Diagnosis and treatment of hemangiopericytoma in the central nervous system

Objective: This study aimed to explore the clinical characteristics and treatment of the hemangiopericytoma (HPC) in the central nervous system. Materials and Methods: Clinical data from 14 patients with HPC in the central nervous system who were followed up for 12–107 months were retrospectively analyzed, and relevant literature was reviewed. Results: All 14 patients underwent surgery and postoperative pathologic diagnosis, including 8 cases of total excision, 3 cases of subtotal excision, and 3 cases of partial excision. There were 7 recurrent cases (50%, 4 cases of total excision, 1 case of subtotal excision, and 2 cases of partial excision, none of them received postoperative radiotherapy) with a median relapse time of 39 months, where the median relapse time after total excision was 41.5 months, and after nontotal excision was 17 months. In addition, patients could survive for a long time after reoperation following relapse and after receiving postoperative radiotherapy. Conclusion: The diagnosis of HPC depends on the pathology. Currently, the surgery and postoperative radiotherapy provide a good treatment results, while the wholeness of surgical resection is of particular importance.
