Objective: The clinical features and the management of alveolar soft part sarcoma (ASPS) are not well known. The efficacy of chemotherapy for soft tissue sarcoma, including high-dose ifosfamide and cisplatin, has not been established yet. Some reports suggest ASPS may occur primarily in bone.
Methods: We report on a series of 57 patients with ASPS over 20 years. Their ages ranged from 7 to 75 years (mean 25).
Results: There were 37 females and 20 males. Thirteen lesions (23%) showed bone involvement at the primary site, and 6 of them were diagnosed as bone tumors at presentation. Thirty-seven patients had distant metastases at presentation. Tumor size, bone involvement at the primary site and the presence of metastases at presentation were prognostic indicators (p < 0.05). Marginal excision with radiotherapy or wide excision without radiotherapy achieved good local control. Chemotherapy was performed in 47 patients with different regimens. Two patients treated with intra-arterial chemotherapy regimens responded partially, but intravenous chemotherapy with high-dose ifosfamide or cisplatin failed.
Conclusions: ASPS can present primarily as a bone tumor. No advantage of chemotherapy with high-dose ifosfamide or cisplatin could be demonstrated.
