Prostate cancer has the third highest incidence of all cancers in men worldwide with incidence and mortality being particularly high in affluent, developed countries. Tea, especially green tea, has demonstrated promise in the prevention of several cancers. Green tea contains several components including catechins, a category of polyphenols that have chemopreventive properties. Although evidence from epidemiological studies is not comprehensive, it is strengthened by animal and in vitro evidence suggesting that consumption of tea is associated with decreased risk or progression of prostate cancer. Emerging evidence and potential biological mechanisms for the role of green tea in prostate cancer prevention are presented in this review.
前列腺癌在全球男性所有癌症中的发病率位居第三，在富裕的发达国家，其发病率和死亡率尤其高。茶，尤其是绿茶，已显示出对多种癌症具有预防作用。绿茶含有多种成分，包括儿茶素，这是一类具有化学预防特性的多酚。尽管流行病学研究的证据并不全面，但动物和体外实验证据进一步支持了这一观点，即饮茶与降低前列腺癌风险或病情进展有关。本文综述了绿茶在预防前列腺癌方面的新证据及潜在生物学机制。
