[背景]评价三维适形放射治疗对恶性肿瘤所致阻塞性黄疸的治疗价值.[病例报告]给10例恶性肿瘤引起的阻塞性黄疸患者进行三维适形放射治疗,单次剂量为200cGy,共22～25次,每日照射1次,每周5次,总剂量为4 400～5 000cGy.放射治疗后3个月时复查CT检查表现,安全缓解为1例,部分缓解为7例,无变化为2例,总有效率为80%(8/10),黄疸消退率为100%;不良反应主要为轻度的恶心、呕吐和乏力.[讨论]三维适形放射治疗对恶性肿瘤引起的阻塞性黄疸疗效较好,不良反应轻.
[Background] To evaluate the therapeutic value of three-dimensional conformal radiotherapy for malignant tumor-induced obstructive jaundice. [Case Report] Ten patients with obstructive jaundice caused by malignant tumors underwent three-dimensional conformal radiotherapy at a single dose of 200 cGy for a total of 22 to 25 times a day, once a day, 5 times a week for a total dose of 4 400 to 5 000 cGy.After 3 months of radiation therapy to review the performance of CT examination, the safety of relief in 1 case, partial relief in 7 cases, no Change to 2 cases, the total effective rate was 80% (8/10), jaundice regression rate was 100%; adverse reactions were mainly mild nausea, vomiting and fatigue [Discussion] three-dimensional conformal radiotherapy caused by malignant tumors Obstructive jaundice better efficacy, mild adverse reactions.
