{Abstract}: BACKGROUND: Cutaneous melanoma (CM) is a malignancy with a variable incidence worldwide and a poor advanced-stage prognosis. Melanoma growth is closely associated with the immune system.
METHODS: A cross-sectional study was performed on CM patients admitted at the Hospital de Cancer de Pernambuco (HCP) between 2015 and 2018. Fifty-one CM patients were included, and 30 healthy individuals. The study aimed to evaluate the association of platelet activation mechanisms and inflammatory response in patients with cutaneous melanoma.
RESULTS: Elevated serum IL10 and low serum TNF levels in CM patients compared to controls (p < 0.05). High IL6 levels in patients with negative lymph nodes LN (-) compared to positive lymph nodes group (LN +, p = 0.0005). Low RANTES levels in patients compared to controls (p < 0.05). Elevated levels of platelet-lymphocyte (PLA), platelet-monocytes (PMA), and platelet-neutrophils (PNA) aggregates were observed in patients compared to controls (p < 0.05). CM patients with stage II had lower PMA levels than stages I and III (p < 0.05). High PMA levels were observed in patients with LN (+) compared to the LN (-) group (p < 0.0001). Patients with SSM had high levels of sCD40L and sCD62P compared to controls (p < 0.05)). High sCD40L levels in stage II compared to the stage III group, and sCD62P in stages I and II compared to the stage III group (p < 0.05). High sCD62P levels in patients with LN (-) compared to the group LN (+) (p < 0.05).
CONCLUSIONS: It was observed the immunosuppressive profile in CM may favor tumor progression. High levels of platelet-leukocyte aggregates, sCD40L, and sCD62P may be associated with the worst prognosis.
