Hexamethylmelamine, methotrexate and 5-fluorouracil (HMF) for progressive ovarian carcinoma during therapy with cis-platinum, cyclophosphamide +/- doxorubicin.

Hexamethylmelamine, methotrexate, and 5-fluorouracil (HMF) is a second-line chemotherapy for patients with ovarian carcinoma refractory to platinum-based regimens. Two of 15 patients with tumor progression treated with HMF alone had objective complete responses while one had a 12-month disease-free interval (DFI). Among 8 patients treated with HMF and either intraperitoneal chromic phosphate and/or alternating platinum-based chemotherapy following second-look surgery which documented persistent carcinoma, 3 have experienced disease-free intervals of 19, 27, and 42 months. However, no one has been cured or had a long-term remission after HMF therapy alone.
