A 20-year review of haemangiopericytoma in Auckland, New Zealand

Abstract

The records of all patients registered with a histological diagnosis of haemangiopericytoma in Auckland between 1970 and 1990 were reviewed retrospectively, with the aim of determining the natural history of the disease and the response to various treatment modalities. A total of 24 patients were identified, having a median age of 45 years. Twenty-one patients (87.5%) underwent surgery; the remaining three were deemed to be unfit for surgery. Seven patients (29%) were treated with surgery alone; nine (37.5%) received a radical course of radiotherapy and three (12.5%) received palliative radiation therapy for pain relief and/or dyspnoea. Five patients (21%) received chemotherapy during the course of their disease. Eight of the 24 patients (33%) were alive and disease free, 13 (54%) having died and three (13%) being lost to follow-up. Seven patients (29%) died as a result of metastatic disease. Three of the seven (43%) who were treated with surgery alone are known to be alive and disease free. The three patients who had received palliative radiotherapy, died within 2 months of completing the latter treatment. Five of the nine patients (56%) receiving a course of radical radiotherapy are alive and disease free at present. No local recurrence was noted following surgical excision and postoperative radical radiotherapy, whilst eight (67%) of those initially treated by excision alone developed recurrent disease. None of the patients treated with chemotherapy obtained significant palliation. Results suggest that adequate surgical excision followed by postoperative radiotherapy is effective in controlling haemangiopericytoma and that metastatic disease is at present invariably fatal. The role of chemotherapy needs further investigation.
