The concept of response to therapy in differentiated thyroid cancer (DTC) was introduced as a dynamic risk stratification used to assess the status of the disease at the time of the evaluation during the follow-up and the risk of recurrence in the future. Our aim in this study was to evaluate the natural course over time of different response to therapy statuses. Methods: We studied 501 nonselected DTC patients (102 males and 399 females) with a median age of 37 years (interquartile range [IQR] 29–48). All patients underwent near-total or total thyroidectomy followed by I-131 ablation (initial management). Results: Of the 501 patients, 387 patients (77.2%) did not have any additional therapuetic interventions after the initial management. In this group, the response to therapy status at the time of the first evaluation after I-131 (median 17 months, IQR 14–22) was an excellent response in 258 (66.7%), an indeterminate response in 101 (26.1%), biochemically incomplete in 17 (4.4%), and structurally incomplete in 11 patients (2.8%). The status changed spontaneously without any intervention in many of them. At the last follow-up visit (median duration 101 months, IQR 71–126), 357 patients (92.2%) achieved an excellent response, 4 (1%) an indeterminate response, 8 (2.1%) a biochemically incomplete status, 16 (4.1%) a structurally incomplete status, and 2 (0.5%) died secondary to DTC with a structurally incomplete status. The response to therapy in the other 114 patients who underwent additional interventions changed from before intervention to the last evaluation as follows: excellent response, 0 to 60 patients (52.6%), indeterminate response, 20 (17.5%) to 1 patient (0.9%), biochemically incomplete 25 (21.9%) to 10 patients (9%), and structurally incomplete 69 (60.5%) to 43 patients (37.7%). Overall, at the last evaluation, 417 (83.2%) were in an excellent response, 5 (1%) in an indeterminate response, 18 (3.6%) in a biochemically incomplete status, 50 (10.2%) in a structurally incomplete status, and 11 (2.2%) died secondary to DTC with a structurally incomplete status. Conclusions: The response to therapy at the initial evaluation is predictive of the long-term outcome. Most patients with the indeterminate response and some in the biochemically incomplete statuses spontaneously regress to an excellent status. Mortality and progression of DTC occur mostly in the structurally incomplete status.

美国甲状腺协会对分化型甲状腺癌治疗状态(动态风险分层)反应的自然过程

分化型甲状腺癌 (DTC) 治疗反应的概念被引入作为动态风险分层,用于评估随访期间评估时的疾病状态和未来复发的风险。我们在这项研究中的目的是评估随着时间的推移对治疗状态的不同反应的自然过程。方法:我们研究了 501 名未选择的 DTC 患者(102 名男性和 399 名女性),中位年龄为 37 岁(四分位距 [IQR] 29-48)。所有患者均接受了近全或全甲状腺切除术,随后进行了 I-131 消融(初始治疗)。结果:在 501 名患者中,387 名患者 (77.2%) 在初始治疗后没有进行任何额外的治疗干预。在该组中,在 I-131(中位 17 个月,IQR 14-22)后第一次评估时对治疗状态的反应在 258 例(66.7%)中有很好的反应,在 101 例(26.1%)中有不确定的反应,17 例(4.4%)生化不完整,11 例(2.8%)结构不完整。状态自发地改变了,其中许多人没有任何干预。在最后一次随访时(中位持续时间 101 个月,IQR 71-126),357 名患者 (92.2%) 达到了极好的反应,4 名 (1%) 反应不确定,8 名 (2.1%) 生化不完全状态,16 (4.1%) 结构不完整状态,2 (0.5%) 继发于 DTC 死亡,结构不完整状态。其他 114 名接受额外干预的患者对治疗的反应从干预前到最后一次评估的变化如下:良好反应,0 至 60 名患者 (52.6%),不确定的反应,20 (17.5%) 至 1 名患者 (0.9%) ),生化不完整 25 (21.9%) 至 10 名患者 (9%),和结构不完整 69 (60.5%) 至 43 名患者 (37.7%)。总体而言,在最后一次评估中,417 人(83.2%)处于良好反应,5 人(1%)处于不确定反应状态,18 人(3.6%)处于生化不完整状态,50 人(10.2%)处于结构不完整状态, 11 例(2.2%)继发于 DTC,结构不完整。5%) 至 1 名患者 (0.9%),生化不完整 25 (21.9%) 至 10 名患者 (9%),结构不完整 69 (60.5%) 至 43 名患者 (37.7%)。总体而言,在最后一次评估中,417 人(83.2%)处于良好反应,5 人(1%)处于不确定反应状态,18 人(3.6%)处于生化不完整状态,50 人(10.2%)处于结构不完整状态, 11 例(2.2%)继发于 DTC,结构不完整。5%) 至 1 名患者 (0.9%),生化不完整 25 (21.9%) 至 10 名患者 (9%),结构不完整 69 (60.5%) 至 43 名患者 (37.7%)。总体而言,在最后一次评估中,417 人(83.2%)处于良好反应,5 人(1%)处于不确定反应状态,18 人(3.6%)处于生化不完整状态,50 人(10.2%)处于结构不完整状态, 11 例(2.2%)继发于 DTC,结构不完整。结论:初始评估时对治疗的反应可预测长期结果。大多数反应不确定的患者和一些处于生化不完全状态的患者会自发地恢复到良好状态。DTC 的死亡和进展大多发生在结构不完整的状态。
