Among 406 patients with Parkinson's disease, the cancer rate (all sites combined) was bout one-third that for the general population. The risk of cancer increased during the treatment period but remained significantly low. Malignant and benign thyroid neoplasms were significantly more frequent than expected among patients with Parkinson's disease. We suggest that high levels of total body potassium in patients with Parkinson's disease is the protective factor against cancer.
在406例帕金森病患者中，癌症发生率（所有部位合并计算）约为普通人群的三分之一。在治疗期间癌症风险有所增加，但仍显著较低。帕金森病患者中恶性和良性甲状腺肿瘤的发生率明显高于预期。我们认为帕金森病患者体内高水平的全身钾是预防癌症的保护因素。
