本文报告应用PDT辅助手术治疗脑肿瘤30例,其中9例为复发性胶质瘤。用HpD4～7mg/kg体重,和激光波长630nm,剂量达到300J/cm~2辅助手术治疗,取得满意效果,且未增加并发症。经随访,平均生存时间已达18.5个月;1、2和3年的生存率分别达到50％、29％和25％。对照组平均生存时间仅达12.5个月;1、2和3年的生存率均为21％。证明PDT辅助手术治疗脑肿瘤优于单纯手术治疗。 This article reports the use of PDT-assisted surgical treatment of 30 brain tumors, of which 9 are recurrent gliomas. With HpD4 ~ 7mg/kg body weight, and the laser wavelength of 630nm, the dose reached 300J/cm~2 adjuvant surgery, with satisfactory results, and no increase in complications. After follow-up, the average survival time has reached 18.5 months; the 1-, 2-, and 3-year survival rates have reached 50%, 29%, and 25%, respectively. The average survival time of the control group was only 12.5 months; the survival rate at 1 year, 2 years, and 3 years was 21%. It is proved that PDT-assisted surgery for brain tumors is superior to surgery alone.
