摘要: 目的 探讨碘-131(131I)质量-剂量关联公式(每克甲状腺组织131I给予量μCi/g=100+甲状腺质量)治疗格雷夫斯甲亢(Graves'甲亢)伴重度甲状腺肿大的临床疗效。方法 随机分配本科Graves'甲亢伴重度甲状腺肿大的患者105例为三组,所有患者诊断明确,采用单光子计算机发射断层(SPECT)质量公式确定甲状腺质量,所有患者首次131I治疗前其质量≥60 g。三组患者131I治疗前皆使用抗甲状腺药物(ATD)治疗,病程24~240月。第1组患者131I剂量按每克甲状腺组织固定剂量 150 μCi 给予;第2组131I剂量按质量切除剂量公式计算之后给予;第3组131I治疗剂量根据质量-剂量关联公式给予(即每克甲状腺组织给予量μCi/g=100+甲状腺质量)。严格随访三组患者甲亢治疗疗效。每组患者需要第二次治疗时所用131I剂量按首次剂量计算方法进行。在131I治疗后6、12月据甲状腺功能状态(甲功)评价甲亢控制疗效。结果 分为甲亢持续(包括甲功正常后复发),甲功正常,甲状腺功能低下(甲减)。结果 ⑴ 三种治疗方法首次131I治疗后,第1组患者数甲亢持续、甲功正常、甲减分别为20、10、5;第2组患者分别为9、20、6;第3组患者分别为8、18、9。⑵ 三种治疗方法首次131I剂量治疗为(20.9±6.0) mCi;(25.9±11.8)和(26.9±9.0) mCi。⑶ 三种治疗方法在所有甲亢患者甲亢控制(甲功正常、甲减)后人均131I剂量和人均131I治疗次数分别为(31.5±16.0) mCi 和 1.86 次;(30.1±18.9) mCi 和 1.31 次;(30.8±15.1) mCi和 1.34 次。结论 质量-剂量关联公式简单可行,可以免除质量切除剂量公式计算的复杂性和有效半减期的测定,同时较每克甲状腺组织固定剂量 150 μCi/g 方法能减少131I治疗次数,值得临床广泛推广。

Abstract: AIM: To explore the efficacy of 131I doses calculated by thyroid weight-dosage relevant formula(131I dosage per g thyroid tissue: μCi/g=100+thyroid weight) on therapy for Graves' hyperthyroidism with large goiter. METHODS: Randomly distributed 105 Graves' hyperthyroidism with large goiter patients into 3 groups, Thyroid weigh was calculated by weight formula of SPECT. 131I Doses of the first group patients calculated by fixed dosage, that was 131I dosage per g thyroid tissue : μCi/g=150uCi; 131I dosage of the second group patients calculated by weight-excision formula, that was D=[d×8×m(g) ]÷[1.6×highest thyroid iodine uptake ×T1/2eff],d=m1÷m2×d0; d0 fixed to 55 Gy. 131I dosage of the third group patients calculated by thyroid weight-dosage relevant formula(131I dosage per g thyroid tissue : μCi/g=100+ thyroid weight). Comparing 131I Doses and frequency of 131I treatment for 3 groups patients when all 105 hyperthyroidism patients achieved normal thyroid function or hypothyroidism. RESULTS: ⑴ After the first 131I therapy, Thyroid function of The first group patients were 20 cases with hyperthyroidism, 10 cases with normal thyroid function and 5 with hypothyroidism; Thyroid function of The second group patients were 9, 20, 6 respectively; and the third group patients were 8, 18 , 9 respectively. ⑵ The doses of the first treatment of 131I were (20.9±6.0) mCi (the first group);25.9±11.8 (the second group) and 26.9±9.0 (the third group) respectively. ⑶ When all 105 hyperthyroidism patients achieved normal thyroid function or hypothyroidism, the mean 131I dose per patient were (31.5±16.0) mCi (the first group);30.1±18.9 (the second group) and 30.8±15.1 (the third group) respectively. CONCLUSION: 131I Doses calculated by thyroid weight-dosage relevant formula was a simple, feasible method. It can avoid the complex of weight-excision formula and could deserve of abroad clinical application.
