目的：探讨三维适形放疗后程补量照射对体部恶性肿瘤的治疗价值。方法：选择体部恶性肿瘤患者180例，先行常规外照射DT 40～50 Gy(20～25 F/4～5 W)，再行三维适形放射治疗后程补量照射治疗，放射源为直线加速器15 MVX射线，利用多叶光栅实现4～6个三维适形照射野，分次治疗方法为DT 4～6 Gy/F，隔日1次，4～6次为1疗程，平均补量为DT 30 Gy(24～36 Gy)。结果：治疗后3～6个月，CT及MRI复查显示：134例原发癌中118例肿瘤缩小或消失(占88%)、46例转移癌中38例肿块明显缩小(占83%)；160例患者KPS评分均有提高(占89%)；全部病例未出现明显放疗并发症。结论：三维适形放射治疗体部恶性肿瘤疗效肯定，其后程补量结合常规放疗对于改善患者预后是有益的。

Objective:To explore the therapeutic value of late course 3 dimensional conformal radiation therapy in the treatment of bodily malignant neoplasms.Methods: One hundred and eighty patients with bodily malignant neoplasms including 46 of 180 patients with metastases tumor were chosen to study. All patents were undertaken late course 3 dimensional conformal radiation therapies after the routine radio therapy. The stereotactic mean radio dose was 30Gy. All patients followed up 3 to 12 months.Results: After the 3 dimensional conformal radiation therapy 3-6 months, 118 in 134 patients primary tumor were reduced, 38in 46 patients metastases tumor were reduced. KPS was improved in 160 of 180 patients. All patients had no radiogical complication.Conclusion: The 3 dimensional conformal radiation therapy for bodily malignant neoplasms were effective, late 3 dimensional conformal radiation therapy combination general radiotherapy were effective in improving prognosis with patients.
