1056P - Survival of patients with advanced melanoma according to first-line treatment and key prognostic factors: Real-world data from GEM1801 study

Background

Targeted therapy (TT) and immune-check-point inhibitors (CPi) have improved the survival of patients (pts) with advanced melanoma (mel). Real-world data of these treatments are needed to confirm the results of clinical trials.

Methods

GEM1801 is a prospective observational study including 400 pts with resected stage III and advanced mel diagnosed since 2018 in Spain. Objectives were to analyze the clinical and pathological presentation, treatment choice and health outcomes. We report results of the advanced mel group (N=357).

Results

Median age was 65 years, ECOG 0-1 85.7% and AJCC 8^th Ed stage IV 90.7% (24.9% a, 14.3% b, 34.7% c and 16.9% d). BRAF, reported in 348 pts (97.5%), was BRAF ^V600-mutated (Mut) in 50.4%. LDH, reported in 302 pts (84.6%), was > upper limit normal (ULN) in 32.8%. First-line (1L) was CPi in 94.9% of BRAF-wild-type (wt) and 30% of BRAF ^V600-Mut. For TT, BRAF+MEK inhibitors were selected as 1L in 64.1% of BRAF ^V600-Mut. Median follow up was 18.3 months (m) (95% CI 17.1-19.6). Median overall survival (OS) was (estimated) 28.1 m (95% CI 22.9-NA). With 1L CPi, 12 and 18-m OS was 79.4% and 70.5% respectively for BRAF-wt group and 90.2% and 82% for BRAF ^V600-Mut (median OS not reached in either group). In pts with BRAF ^V600-Mut and TT, 12 and 18m OS was 62.4% and 50.9% respectively and median OS 18.5m (95% CI 13.3-28.1). OS according to ECOG, LDH and M1 stage is in the table G3-4 AEs appeared in 7.9% of pts treated with TT and 9.2% with CPi. Table: 1056P

Conclusions

Survival of pts with advanced mel is similar to reported in clinical trials. 1L TT was chosen for 2/3 BRAF ^V600-Mut cases while 1/3 were treated with CPi. OS in pts treated with CPi seems superior to TT in BRAF ^V600-Mut group although potential bias must be considered since stage, LDH and ECOG impacted OS.
