Recent studies in humans have shown an association between sleep-disordered breathing (SDB), including overnight hypoxia, and the incidence and mortality of cancer, but no study has focused on a specific type of cancer. The objective of this study was to analyze the relationship between some markers of cutaneous malignant melanoma (CMM) aggressiveness and the severity of SDB.Methods. We performed a prospective, multicenter observational study in 56 consecutive patients diagnosed with CMM. Measurements of CMM aggressiveness included: number of mitosis/mm2, Breslow Index, presence of ulceration and growth rate of melanoma (GRM). Every participant underwent a diagnostic respiratory polygraphy. Multivariate analyses were used to investigate the independent relationship between SDB severity measured by the apnoea-hypopnoea index (AHI) and oxygen desaturation indexes (ODI3% and ODI4%) and markers of CMM aggressiveness.Results. The prevalence of SDB (AHI≥5) in the cohort was 60.7% and severe SDB (AHI≥30) was present in 14.3% of the patients. In fully adjusted multivariate analyses, AHI (OR 1.17; 95%CI 1.03-1.34), ODI3% (OR 1.14; 95%CI 1.03-1.26) and ODI4% (OR 1.3; 95%CI 1.04-1.45) were independently associated with an increased GRM. Furthermore, AHI, ODI4% and ODI3% correlated with other aggressiveness factors of CMM, such as the Breslow Index, presence of ulceration and mitotic index.Conclusion. SDB severity independently predicts aggressiveness of cutaneous malignant melanoma.
