A phase II trial of paclitaxel in the treatment of recurrent or metastatic soft tissue sarcomas or bone sarcomas.
The study aimed to determine the activity and toxicity of taxol in the treatment of recurrent or metastatic soft tissue sarcomas or osteosarcomas. The major findings are that five patients had stable disease after two cycles of chemotherapy but two of these patients were subsequently removed from the study at their own request. The other three patients progressed after an additional two cycles of chemotherapy. Seven patients progressed during the first two cycles and were removed from the study. One patient completed only one cycle of therapy and was deemed inevaluable for study response. There were eight episodes of grade 3 or 4 neutropenia and two episodes of grade 3 thrombocytopenia. One patient experienced grade 3 neurological toxicity and one patient grade 3 mucositis. Two patients are currently alive with progressing disease and one patient is alive with no evidence of disease after undergoing surgery and radiotherapy. The principal conclusions are that Paclitaxel is ineffective in treating recurrent or metastatic soft tissue sarcoma and osteosarcoma. Treatment at this dose is quite myelosuppressive, but toxicity is generally manageable. Further study of this agent is not justified in this setting.
