Multidrug chemotherapy increases responses in advanced soft tissues sarcoma. Can a 20% increase of relative dose intensity of the MAID regimen, more improve responses? From 1994 to 1997, 162 patients were randomized in a phase III study to the conventional drug combination (6 cycles of MAID: 60, 7,500, 900 mg/m2 for doxorubicin, ifosfamide and dacarbazine respectively), or at doses 20–33% higher per cycle (5 cycles of intensified MAID for similar cumulative doses) with systematic G-CSF. Primary endpoint was response rate; secondary were toxicity, event-free and overall survival. The objective response rate in assessable patients was 38% with intensified MAID and 35% with MAID (p = 0.72). Event-free and overall survivals were similar in both arms. Only grade 3–4 thrombocytopenia and anemia were significantly higher in intensified arm. Treatment with intensified MAID did not improve response rate neither survival and cannot be recommended for advanced or metastatic soft tissue sarcoma.
