This paper reports 50 cases of gastrointestinal tumors treated by photodynamic therapy. The dose of HpD was 5 mg/kg. Fourty-eight to 72 hours after HpD injection, laser (wavelength 630 nm, power density 100-250 J/cm2), transmitted through a quartz fiber, was given. The criteria of therapeutic effectiveness were: complete remission (CR), significant remission (SR), minor remission (MR) and no remission (NR). All patients received endoscopic examination 4 weeks after treatment. No severe complication was observed. Thirty-eight of 50 cases gave CR, SR or MR (76%). The factors effecting treatment are discussed.
本文报道了50例接受光动力疗法治疗的胃肠道肿瘤患者。血卟啉衍生物（HpD）的剂量为5毫克/千克。注射HpD后48至72小时，通过石英纤维传输的激光（波长630纳米，功率密度100 - 250焦/平方厘米）进行照射。治疗效果标准为：完全缓解（CR）、显著缓解（SR）、轻度缓解（MR）和无缓解（NR）。所有患者在治疗后4周接受内镜检查。未观察到严重并发症。50例患者中有38例达到CR、SR或MR（76%）。文中讨论了影响治疗的因素。
