美国 Temple 大学将试验一种可调染料激光器疗法,这种疗法依靠激光激活的化学反应去杀死癌细胞,但不会损害健康细胞。采用这种方法可比外科手术方法更有效地探查出和杀死膀胱与口腔肿瘤中的癌细胞。激光与为治疗而在48小时注入病人体内的二血卟啉醚进行反应。还有9所医院也将试验这种技术。(美刊《Technology Update》,1986年10月20日,Vol. Temple University in the United States will experiment with a tunable dye laser therapy that relies on laser-activated chemical reactions to kill cancer cells without damaging healthy cells. Using this method can detect and kill cancer cells in bladder and oral tumors more effectively than surgical methods. The laser reacted with dihematoporphyrin ether injected into the patient for treatment at 48 hours. There are also 9 hospitals that will also test this technology.
