Real-world treatment patterns and clinical outcomes in advanced cutaneous melanoma patients in France

Abstract

Background: Since 2011, the management of advanced melanoma has radically changed with the availability of new therapies (immunotherapy and BRAF-targeted therapy) and with BRAF testing.

Objectives: Following the introduction of these new therapies, the objectives of this AMEL study were to describe treatment patterns and evaluate overall survival (OS) among unresectable stage III/IV melanoma patients, in a real-life setting in France.

Methods: The AMEL study is a multicentre retrospective record review study. Thirty-three physicians working in 33 unique treatment centres participated in the study. Two hundred and sixty-four patients diagnosed between 1 January 2012 and 31 October 2012 with unresectable stage III/IV melanoma were included in the study.

Results: 94.7% of the patients received a first-line antitumour drug treatment, 62.5% a second-line treatment while 26.9% received a third-line treatment with no significant differences between patients with a BRAF mutation (50.4%) and BRAF wild type (47.0%). First-line treatment differs according to the BRAF status: 74.8% of patients with a BRAF mutation received a BRAF inhibitor while 79.3% of the BRAF wild-type patients were treated with conventional chemotherapy. In second line and over, the treatment patterns were more heterogeneous, depending on the BRAF mutation, the treatment received previously, the speed of progression of the disease and the availability of immunotherapy at the time the treatment was initiated.

Conclusion: Regardless of the BRAF mutation status, the median OS of patients was 16 months (95% CI = 14-18). Compared to a similar study conducted in 2007 (MELODY), a gain of 4 months is observed. The gain seems to be higher for patients with a BRAF mutation (18 months) than for those without a BRAF mutation (14 months). The OS of patients who sequentially received both a BRAF inhibitor and ipilimumab (28 months) highlights the benefit of this treatment sequence.
