多项实验研究与流行病学调查表明 :非甾体抗炎药物阿司匹林可降低结肠直肠癌及腺瘤的发生。腺瘤是大多数结肠直肠癌的早期表现 ,预防腺瘤的发生也极有可能降低结肠直肠癌的发病率。为此 ,此文作者将阿司匹林作为结肠直肠腺瘤的化学预防药物 ,进行了一项随机双盲的实验研究。方 A number of experimental studies and epidemiological investigations show that aspirin, a non-steroidal anti-inflammatory drug, can reduce the incidence of colorectal cancer and adenoma. Adenoma is an early manifestation of most colorectal cancers and prevention of adenoma is also likely to reduce the incidence of colorectal cancer. To this end, the author of aspirin as a chemoprevention drug for colorectal adenomas, conducted a randomized double-blind experimental study. square
