BACKGROUND: A phase I study was designed for the amalgamation of two previously studied antisarcoma regimens (ifosfamide+doxorubicin and mitomycin+doxorubicin+cisplatin) supported by molgramostim. Thus, we hoped to develop a better regimen for the treatment of advanced sarcomas. PATIENTS AND METHODS: Fifteen adult advanced sarcoma patients and six other patients were registered and sequentially assigned to receive three progressively more myelosuppressive levels of chemotherapy: level I-ifosfamide 2500 mg/m2 + doxorubicin 40 mg/m2 + cisplatin 60 mg/m2 all given on day 0, followed by molgramostim 5 micrograms/kg every 12 hours for 14 days; level II-exactly the same chemotherapy from level I given on day 1 preceded on day 0 by ifosfamide 2500 mg/m2 and an additional four days of molgramostim given on days-6 through-3; level III-same as level II except for the addition of mitomycin 4 mg/m2 immediately prior to cisplatin on day 1. MENSA 500 mg/m2 was given five times on each day that involved ifosfamide treatment. For all levels, treatment was repeated at four-week intervals. RESULTS: Preliminary results and toxicity were reported three years ago (J Natl Cancer Inst 86: 312-4, 1994). Mature results confirm these unexpectedly favorable results with five advanced sarcoma patients still surviving after more than three years (four more than four years). HYPOTHESIS: Molgramostim given subcutaneously in a relatively intensive schedule might enhance the antitumor effects initiated by cytotoxic drugs in patients with advanced sarcomas. This idea should be tested formally in phase III studies.
