Temodar for melanoma – pro

Temozolomide is a cytotoxic prodrug that, when hydrolyzed, inhibits DNA replication by methylating nucleotide bases. In preclinical testing, temozolomide has shown a broad spectrum of antineoplastic activity. In a randomized phase III trial involving patients with advanced malignant melanoma, temozolomide produced an objective response rate of 13.5% compared with 12.1% in the dacarbazine group. Temozolomide produced a modest increase in PFS time compared with dacarbazine (1.9 vs 1.5 months). There was a statistically significant difference in favor of the temozolomide-treated group in the physical functioning and cognitive functioning domains.

The guidelines support the proposed recommendation. It is reasonable to use temozolomide at a dose of 200 mg/m2 orally for five days every four weeks as initial systemic treatment for patients with unresectable metastatic malignant melanoma. It is listed by NCCN.
