近年来,已广泛应用纤维内窥镜,X线造影、脱落细胞学等检查方法诊断消化道癌。但这些检查方法由于种种条件的限制尚不能普遍应用于大规模人群的普查。因此当前各地正在从事这方面的研究工作,并尽可能利用一滴血、一泡尿为标本,试图建立一种简易,效果可靠的筛选方法。宋德中氏报告以尿液玫瑰红反应检查12例癌患者全为阳性,48例非癌患者 In recent years, fiber endoscopes, X-ray radiography, and exfoliative cytology have been widely used to diagnose gastrointestinal cancer. However, these inspection methods cannot be universally applied to large-scale population surveys due to various conditions. Therefore, current research work in this area is being carried out, and as far as possible, a drop of blood and a blister of urine are used as specimens, trying to establish a simple, reliable screening method. Song De’s Zhongshi reports that 12 patients with cancer were all positive and 48 non-cancer patients were examined with urine rose red reaction.
