近年研究表明．手术、放疗结合化疗尚难以改善晚期胃癌生存率及生存质量[1]。尤其是老年食管、胃癌患者．全身化疗不仅反应重，且可致机体免疫机能下降，预后更差。2年来，我们用自行研制的微粒活性炭（AT）作为载体，吸附丝裂霉素（MMC），在内镜下向食管、胃癌患者的瘤体内注
Recent studies have shown. Surgery, radiotherapy combined with chemotherapy is still difficult to improve the survival rate and quality of life of advanced gastric cancer [1]. Especially elderly esophageal and gastric cancer patients. Systemic chemotherapy is not only of heavy reaction, but also can cause the body’s immune function to decline and the prognosis is worse. In the past 2 years, we have used self-developed microparticle activated carbon (AT) as a carrier to adsorb mitomycin (MMC) and intravitreal injections into esophageal and gastric cancer patients.
