A prospective randomized multicentre phase III trial of fotemustine plus whole brain irradiation versus fotemustine alone in cerebral metastases of malignant melanoma.

The main objective of this prospective multicentre randomized phase III study was to compare a combined regimen of fotemustine plus whole brain irradiation with fotemustine alone in terms of cerebral response and time to cerebral progression in patients with melanoma cerebral metastases. Seventy-six patients were randomized to receive either fotemustine (arm A, n = 39) or fotemustine plus whole brain irradiation (arm B, n = 37). Fotemustine was administered intravenously at 100 mg/m(2) on days 1, 8 and 15, followed by a 5 week rest period, then every 3 weeks in non-progressive patients. In arm B, concomitant whole brain irradiation was performed at a total dose of 37.5 Gy (2.5 Gy/day on days 1-5 for three consecutive weeks). Although patients who received fotemustine alone had worse prognostic factors, there was no significant difference in cerebral response (arm A, 7.4%, arm B, 10.0%) or control rates (objective responses plus stable disease) after 7 weeks (arm A, 30%; arm B, 47%) or in overall survival (arm A, 86 days; arm B, 105 days). However, there was a significant difference in favour of arm B for the time to cerebral progression (P = 0.028, Wilcoxon test). In conclusion, fotemustine plus whole brain irradiation delayed the time to cerebral progression of melanoma cerebral metastases compared with fotemustine alone but without a significant improvement in terms of objective control or overall survival.
