摘要
采用立体定向技术可以准确的把放射性核素置入脑瘤进行近距离放疗。本文报告1991年12月31日以来立体定向对脑深部肿瘤142例进行了铱-192后装管置入进行间质内放疗。男106例,女36例,年龄5 ̄77岁,平均35.9岁,肿瘤位置:额叶内29例,顶叶内25例,颞叶内5例;枕叶内6例;脑实质内多发灶18例,丘脑基底节区28例,三脑室后部13例,鞍区8例;其它部位共16例,立体定向活检证实;
CT-Guided stereitactic procedures make it easy to place radioactive material in tu-mors at exact and reproducible sites. A stereotactic program of interstitial iridium-192 radiothera-py in deep-seated brain tumors has been applied in 142 cases since December 31, 1992. There were106 males and 36 females, ranging in age from 5-77 years (median 35. 9 years). Primary and re-current tumor sites included the frontal lobe (29), parietal lobe (25), temporal lobe (15), multi-ple 18, Posterior of third ventricle (13), basal ganglion (28), occipital lobe (6), and other lesions(10). Stereotactic biopsy were astrocytoma in 80 cases, glioblastoma in 13, oligodendroglioma in5, ependyma in 2, metastasis in 12, lymphoma in 2, meningioma in 4, pinealocytoma in 13, cran-iopharyngioma in 5, chordoma in 2, colloid cyst in 1, engioneoplasm in 1 and medulloblastoma in2. 120 Patients were up up followed from 1 to 4 years, with a median of 2. 2 years. Our resultsshowed that the median survival of this group of patients was 26 months which wasw significantlyhigher than the median survival of 13 months for a group of similar patients treated without an im-plant boost.
