Resumen:
Epidemiological associations linking between obstructive sleep apnea and poorer solid malignant tumor outcomes have recently emerged. Putative pathways proposed to explain that these associations have included enhanced hypoxia inducible factor (HIF)-1 alpha and vascular endothelial growth factor (VEGF) cell expression in the tumor and altered immune functions via intermittent hypoxia (IH). Here, we examined relationships between HIF-1 alpha and VEGF expression and nocturnal IH in cutaneous melanoma (CM) tumor samples. Prospectively recruited patients with CM tumor samples were included and underwent overnight polygraphy. General clinical features, apnea-hypopnea index (AHI), desaturation index (DI4%), and CM characteristics were recorded. Histochemical assessments of VEGF and HIF-1 alpha were performed, and the percentage of positive cells (0, < 25, 25-50, 51-75, > 75%) was blindly tabulated for VEGF expression, and as 0, 0-5.9, 6.0-10.0, > 10.0% for HIF-1 alpha expression, respectively. Cases with HIF-1 alpha expression > 6% (high expression) were compared with those < 6%, and VEGF expression > 75% of cells was compared with those with < 75%. 376 patients were included. High expression of VEGF and HIF-1 alpha were seen in 88.8 and 4.2% of samples, respectively. High expression of VEGF was only associated with increasing age. However, high expression of HIF-1 alpha was significantly associated with age, Breslow index, AHI, and DI4%. Logistic regression showed that DI4% [OR 1.03 (95% CI: 1.01-1.06)] and Breslow index [OR 1.28 (95% CI: 1.18-1.46)], but not AHI, remained independently associated with the presence of high HIF-1 alpha expression. Thus, IH emerges as an independent risk factor for higher HIF-1 alpha expression in CM tumors and is inferentially linked to worse clinical CM prognostic indicators.
