Fotemustine compared with dacarbazine in patients with disseminated malignant melanoma: a phase III study.

PURPOSE: To compare fotemustine and dacarbazine (DTIC) in terms of overall response rate (ORR) as primary end-point and overall survival, duration of responses, time to progression, time to occurrence of brain metastases (BM), and to assess safety and quality of life in patients with disseminated cutaneous melanoma. PATIENTS AND METHODS: Patients received either intravenous fotemustine 100 mg/m2 weekly for 3 weeks or DTIC 250 mg/m2/d for 5 consecutive days every 4 weeks (two cycles). Nonprogressive patients received a maintenance treatment every 4 weeks (fotemustine 100 mg/m2 or DTIC 250 mg/m2 for 5 days). RESULTS: Two hundred twenty-nine patients were randomly assigned to fotemustine or DTIC arms. The best ORR was higher in the fotemustine arm than in the DTIC arm in the intent-to-treat population (n=229; 15.2% v 6.8%; P=.043) and in full analysis set (n=221) (15.5% v 7.2%; P=.053). Similar median durations of responses (5.8 months with fotemustine v 6.9 months with DTIC) and time to progression (1.8 v 1.9 months, respectively) were observed. In patients without BM at inclusion, the median time to BM was 22.7 months with fotemustine versus 7.2 months with DTIC (P=.059). Median survival was 7.3 months with fotemustine versus 5.6 months with DTIC (P=.067). The main toxicity was grade 3 to 4 neutropenia (51% with fotemustine v 5% with DTIC) and thrombocytopenia (43% v 6%, respectively). No significant difference was noted for quality of life between arms. CONCLUSION: ORR was higher in the fotemustine arm compared to the DTIC arm in first-line treatment of disseminated melanoma. A trend in favor of fotemustine in terms of overall survival and time to BM was evidenced.

Germline mutations of the INK4a-ARF gene in patients with suspected genetic predisposition to melanoma.

Germline anomalies of the INK4a-ARF and Cdk4 genes were sought in a series of 89 patients suspected of having a genetic predisposition to melanoma. Patients were selected based on the following criteria: (a) familial melanoma (23 cases), (b) multiple primary melanoma (MPM; 18 cases), (c) melanoma and additional unrelated cancers (13 cases), (d) age at diagnosis less than 25 years (21 cases), and (e) nonphoto-induced melanoma (NPIM; 14 cases). Mutations of INK4a-ARF and Cdk4 were characterised by automated sequencing, and germline deletions of INK4a-ARF were also examined by real-time quantitative PCR. Seven germline changes of INK4a-ARF, five of which were novel, were found in seven patients (8%). Four were very likely to be pathogenic mutations and were found in three high-risk melanoma families and in a patient who had a pancreatic carcinoma in addition to melanoma. Three variants of uncertain significance were detected in one MPM patient, one patient <25 years, and one NPIM patient. No germline deletion of INK4a-ARF was found in 71 patients, and no Cdk4 mutation was observed in the 89 patients. This study confirms that INK4a-ARF mutations are infrequent outside stringent familial criteria, and that germline INK4a-ARF deletions are rarely involved in genetic predisposition to melanoma.
