Among the individuals with PD who died, the authors observed 48 cases of melanoma. The estimated RR for melanoma in patients with PD who died was 1.95; and an increased risk for death with PD was noted among the patients with melanoma (RR, 1.65). Researchers also found prostate cancer in 212 patients with PD who died (RR, 1.71) and an increased risk for death with PD was found among the prostate cancer patients (RR, 1.39), according to the results.
"Thus, these data argue strongly for a significant shared genetic risk for specific cancers on the one hand and neurodegeneration on the other. .These studies provide a framework for future definition of the precise nature of shared genetic variation leading to neurodegeneration in some individuals, but skin or prostate cancers in others, and they may influence strategies for skin and prostate cancer screening," the authors conclude.
