[Preliminary result of advanced soft tissue sarcoma treated by MAID regimen].

BACKGROUND &

OBJECTIVES

Chemotherapy combined with other therapeutic modalities is the main option for advanced and metastatic soft tissue sarcoma(STS). So far there is no standard regimen for STS yet. Adrimycin, ifosfamide, and dacarbazine are the most effective agents at present. The purpose of this clinical trial was to evaluate the efficacy and toxicity of MAID regimen (mesna/ifosfamide + Adriamycin + dacarbazine) in the treatment of advanced soft tissue sarcoma.

METHODS

Twenty-two patients with advanced STS were treated by MAID(Adriamycin 60 mg/m2, ifosfamide 6,000 mg/m2, and dacarbazine 1,000 mg/m2). These drugs were administered as continuous intravenous infusion for 72 hours while mesna was infused continuously for 96 hours.

RESULTS

Partial response rate was 36.4% without complete remission. The duration of response ranged from 2-10 months with median of 4.6 months. Main toxicities were myelosuppression, gastrointestinal toxicity and alopecia. Percentage of leucopenia, nausea/vomiting, and alopecia in WHO grade III and IV were 63.6%, 27.3%, and 50%, respectively.

CONCLUSIONS

The response rate of MAID for advanced STS was not satisfactory with evident myelosuppression. Further study on new anti-cancer agents and regimen are needed.
