对６例原发性肝癌患者进行超声引导下１３１Ⅰ－碘化油内放射治疗。结果表明：该组６例病人穿刺全部成功，１３１Ⅰ－碘化油均浓集于肿瘤内，声像图表现为“白色云团”一样强回声，无声影。核素显像１３１Ⅰ－碘化油在肿瘤内有效半衰期为（６．２２±０．６１）ｄ，瘤／肝比值为（９．１５±３．４１），肺／肝＋肺比率为（５．１９±２．２８）。５例病人肿块明显缩小，ＡＦＰ迅速下降，无并发症发生。该文认为超声引导下１３１Ⅰ－碘化油内放射治疗原发性肝癌是一种简单、安全和有效的方法。
Ultrasound-guided 131I-iodinated intravital radiotherapy was performed on 6 patients with primary liver cancer. The results showed that the puncture was successful in all 6 patients in this group. The 131I-iodinated oil was concentrated in the tumor. The sonogram showed a strong echo of “white clouds” and no acoustic shadow. The effective half-life of radionuclide 131I-iodinated oil in tumors was (6.22±0.61) d, tumor/liver ratio was (9.15±3.41), lung/liver+lung ratio was (5 .19±2.28). In 5 patients, the mass was significantly reduced, AFP decreased rapidly, and no complications occurred. This article believes that ultrasound-guided 131I-iodinated oil radiotherapy for primary liver cancer is a simple, safe and effective method.
