从1986年5月至1990年1O月间,作者等采用血卟啉衍生物(HPD)对50例胃肠道癌肿进行了诊断和治疗。50例患者中,男性40例,女性10例,年龄28～84岁,食管癌30例,胃癌20例。带有磁性蕊香红B的氩离子激光作为光源。病变部位使用200～400mW照射。经石英纤维于表面距焦,距病变处1～2cm注射HPD(5mg/kg)后48～72小时,采用动力氩离子激光持续照射15～20分钟。40例行荧光染色检查,35
From May 1986 to January 1990, the authors used hematoporphyrin derivatives (HPD) to diagnose and treat 50 cases of gastrointestinal cancer.
