維他命C對防治癌症的檢視

The role of vitamin c for the treatment of cancer

許多研究指出，高濃度維他命C有抗癌作用。臨床前的研究亦認為，靜脈注射維他命C對癌症治療有助益，唯臨床的研究尚無結論。在藥理劑量達高濃度，即維他命C在血漿濃度達1 mM，便會減少細胞增殖、發炎和產生自然凋亡，因此，高濃度靜脈注射維他命C可作為現階段的輔助治療，或替代治療來防治癌症。既然維他命C便宜、副作用少，有效提升癌症患者的生活品質，加上有部份的抗癌作用，因此強烈建議使用靜脈注射維他命C來治療某些惡性腫瘤。

It has been shown that the concentration of vitamin C may be significant decreased in cancer patients compared to healthy subjects. Although the results of preclinical studies showed promising efficacy of the intravenous administration, the result of clinical trials are inconclusive and have not delivered solid evidence of clinical efficacy in the treatment of cancer. At the pharmacological dose (1 mM) vitamin C decreased cell proliferation, and inflammation, and induced apoptosis. Therefore, high doses of vitamin C are administered intravenously by complementary and alternative medicine as an additional treatment for patients with respect to its low price, limited number of side effects, improvement of the quality of life of cancer patients and somewhat anti-cancer activity, it seems there is a solid rationale for the possible introduction of vitamin C administration via intravenous infusion to the treatment of selected malignant neoplasms.
