Abstract

OBJECTIVE

This prospective study evaluated the recurrence rate in low-risk patients with papillary thyroid cancer (PTC) who presented slightly elevated thyroglobulin (Tg) after thyroidectomy and who did not undergo ablation with131I.

SUBJECTS AND METHODS

The study included 53 low-risk patients (nonaggressive histology; pT1b-3, cN0pNx, M0) with slightly elevated Tg after thyroidectomy (> 1 ng/mL, but ≤ 5 ng/mL after levothyroxine withdrawal or ≤ 2 ng/mL after recombinant human TSH).

RESULTS

The time of follow-up ranged from 36 to 96 months. Lymph node metastases were detected in only one patient (1.9%). Fifty-two patients continued to present negative neck ultrasound. None of these patients without apparent disease presented an increase in Tg.

CONCLUSIONS

Low-risk patients with PTC who present slightly elevated Tg after thyroidectomy do not require ablation with 131I.

摘要

目的

本前瞻性研究评估了甲状腺乳头状癌(PTC)低风险患者在甲状腺切除术后甲状腺球蛋白(Tg)轻度升高且未接受131I消融治疗时的复发率。

对象与方法

该研究纳入了53例低风险患者(组织学无侵袭性;pT1b - 3,cN0pNx,M0),这些患者在甲状腺切除术后Tg轻度升高(>1 ng/mL,但在停用左甲状腺素后≤5 ng/mL或在重组人促甲状腺素刺激后≤2 ng/mL)。

结果

随访时间为36至96个月。仅1例患者(1.9%)检测到淋巴结转移。52例患者颈部超声检查持续为阴性。这些无明显疾病的患者中,Tg均未升高。

结论

甲状腺切除术后Tg轻度升高的PTC低风险患者无需接受131I消融治疗。
