摘　　要：目的观察^131Ⅰ-肿瘤细胞核人鼠嵌合单克隆抗体（^131Ⅰ-chTNT）放射免疫治疗中晚期肺癌的疗效。方法15例确诊的中晚期肺癌患者，通过静脉注射^131Ⅰ-chTNT进行治疗，并于治疗后1、3、5、7、9、15d行动态核素显像，以客观反应率（ORR）来评估疗效。结果完全反应者（CR）1例，部分反应者（PR）5例，7例无变化（NC），2例出现病情进展（PD），客观反应率为40％（完全反应＋部分反应）。核素显像显示，^131Ⅰ-chTNT能在较长时间内稳定地分布在肺肿瘤病灶处。主要的副作用为轻度的和可逆的骨髓抑制。结论^131Ⅰ-chTNT治疗中晚期肺癌近期疗效良好，治疗后动态放射性核素显像可客观显示病灶放射性摄取情况。Objective To assess the therapeutic efficacy of Iodine-131-labeled chimeric tumor necrosis treatment radioimmunotherapy（^131Ⅰ-ehTNT） in patients with advanced lung cancer. Methods 15 patients confirmed diagnosis of advanced lung cancer were treated with intravenous injections of ^131Ⅰ-chTNT, and radionuclide imaging was performed at 1,3,5,7,9,15 day after therapy, the objective response rate（ORR） was used to assess the therapeutic efficacy. Results The results showed an ORR of 40% （ complete response, 1 case ; partial response,5 cases ; no change, 7 cases ; and progressive disease, 2 cases） ; radionuelide imaging study demonstrated that ^131Ⅰ-chTNT had a long and stable retention in lung tumor. The most obvious adverse side effect was mild and reversible bone marrow suppression. Conclusion The short-term effect of ^131Ⅰ-chTNT in patients with advanced lung cancer is good, radionuclide imaging after therapy can objectively show localization of the radioactivity in tumors
