Phase I trial of high-dose melphalan, high-dose etoposide and autologous bone marrow re-infusion in solid tumors: an Eastern Cooperative Oncology Group (ECOG) study.
The purpose of this work was to determine the maximum tolerated (phase II) dose of melphalan and etoposide that can be given in conjunction with autologous BM re-infusion in patients who have refractory or relapsed solid tumors. Twenty-six patients with refractory or relapsed breast cancer (n = 15), small cell lung cancer (n = 1), ovarian cancer (n = 3), colorectal cancer (n = 3) or malignant melanoma (n = 4) were enrolled and treated in this phase I study. Patients ranged in age from 31 to 60 years (median 44.5 years). Melphalan 180 mg/m2 (60 mg/m2/day for 3 consecutive days i.v. over 30 min) and etoposide 1200-3600 mg/m2 (400-1200 mg/m2/day for 3 consecutive days i.v. over 4 h) were given followed by autologous BM infusion 60-72 h after completion of chemotherapy. Ten patients received GM-CSF or G-CSF therapy after marrow re-infusion. Regimen-related toxicities included fever, pancytopenia, mucositis, nausea, vomiting, diarrhea, esophagitis, hepatic dysfunction and infection. Neutrophils recovered to > 500 x 10(6)/l and platelets recovered to > 20 x 10(9)/l (without transfusions) a median of 17 days and 20.5 days after marrow infusion, respectively. Dose-limiting toxicity occurred at an etoposide dose of 3600 mg/m2, since 4 of 6 patients treated at this dose level experienced grade 4 NCI Common Toxicity Criteria (mucositis (n = 3) and infection (n = 1)). Complete responses were noted in 7 patients (breast cancer (n = 5), colorectal cancer (n = 1) and melanoma (n = 1)); partial responses were observed in 5 patients. Melphalan 180 mg/m2 and etoposide 3000 mg/m2 is a potent high-dose chemotherapy regimen with significant antineoplastic activity, particularly for breast cancer, and has acceptable toxicity when administered in conjunction with autologous BM re-infusion.
