e13635 Background: Melanoma is an aggressive skin malignancy with rising global incidence, for which checkpoint inhibitors (CPI) and BRAF-targeted therapies are standard of care in advanced disease. However, access to molecular diagnostics and CPI remains limited in conflict-affected regions such as Syria. Real-world data describing melanoma management in this setting are scarce. Methods: We conducted a retrospective study of all patients diagnosed with melanoma between 2022 and 2024 at Al-Bairouni University Hospital (ABUH), Syria’s primary oncology referral center. Demographic and clinical characteristics were analyzed for the entire cohort, and patients with advanced disease were evaluated for molecular testing and treatment patterns. Semi-structured interviews were conducted in a mixed advanced cancer subset (N = 35) to explore barriers to immunotherapy access. Results: Among 115 patients with melanoma, the median age at diagnosis was 57 years (IQR 44.5–67), and 54.7% were male. At presentation, 18.3% had stage I disease, 1.7% stage II, 2.6% stage III, and 40.9% stage IV disease; staging was unavailable in 36.5%. Among patients with advanced melanoma (n = 47), BRAF testing was performed in 17 (36.2%), with targeted therapy administered to 5/16 BRAF-positive patients. Only 7/47 patients (14.9%) received CPI, primarily as monotherapy. In the qualitative subset (predominantly lung cancer), five major barriers to immunotherapy access emerged: financial toxicity (n = 22), limited drug availability (n = 9), limited patient awareness (n = 8), geographic/logistical challenges (n = 5), and system delays (n = 4). Conclusions: Despite a substantial burden of advanced melanoma, access to molecular testing, targeted therapy and CPI in Syria remains limited. Qualitative findings highlight financial and structural barriers as primary drivers of limited access, underscoring the need for improved drug availability, diagnostic infrastructure, and patient education in conflict-affected settings.
