摘    要:
目的分析比较三种光敏剂介导的光动力疗法治疗上消化道癌的近期疗效和不良反应。方法上消化道癌患者181例,分别应用血卟啉衍生物(67例)、血卟啉单甲醚(58例)及卟吩姆钠(56例)作为光敏剂,给药剂量分别为5、6和2mg/kg,于照光前6—24h静脉滴注。分别应用金蒸气激光和半导体激光作为治疗光源,功率密度200~400mW/cm^2,能量密度100~300J/cm^2。治疗1-5次后评价疗效:完全疗效(cR)、明显疗效(PR)、稍有疗效(MR)、无效(NR)。结果血卟啉衍生物组67例患者,cR5例(7.5%),PR40例(59.7%),MR16例(23.9%),NR6例(9.0%)。血卟啉单甲醚组58例患者,CR5例(8.6%),PR33例(56.9%),MR14例(24.1%),NR6例(10.3%)。卟吩姆钠组56例患者,CR6例(10.7%),PR33例(58.9%),MR12例(21.4%),NR5例(8.9%)。三组病例均未出现严重不良反应。结论血卟啉衍生物、血卟啉单甲醚和卟吩姆钠三种光敏光动力疗效治疗临床各期上消化道癌疗效相近,不良反应轻,耐受性好,是较好的姑息治疗手段。

关 键 词:激光  光敏剂  光动力疗法  上消化道肿瘤

Abstract:
Objective To study the clinical efficacy and adverse effects of photodynamic therapy for the upper gastrointestinal tract cancers by three different photosensitizers. Methods Totally 181 patients with upper gastrointestinal cancers in different clinical stages were treated with photodynamic therapy.HpD,HMME and porfimer sodium(Photofrin) were used as photosensitizers,which were given intravenously in a dose of 5mg/kg,6mg/kg or 2mg/kg 6-24 hours before irradiation,respectively.Gold vapor laser and diode lase...
Keywords:Laser  Photodynamic therapy  Upper gastrointestinal cancer
