Abstract

BACKGROUND:Postoperative hypocalcemia because of hypoparathyroidism is the most common complication of total thyroidectomy in children. We hypothesized that most children with postoperative hypocalcemia would be eucalcemic by 12 mo and sought to define risk factors for permanent hypoparathyroidism. METHODS:We retrospectively reviewed children who underwent total thyroidectomy at a single children's hospital from 2012 to 2019. Patients with prior neck surgery were excluded. Indication for operation, final pathologic diagnosis, and postoperative serum calcium up to 12 mo were recorded. Permanent hypoparathyroidism was defined as supplemental calcium requirement beyond 1 y postoperatively. RESULTS:Sixty-eight patients underwent total thyroidectomy. Graves' disease was the most common benign indication for surgery (38 patients). Twenty-six patients (38%) had cancer on final pathology. Central lymph node dissection (CLND) was performed in 12 cancer patients. Twenty-eight patients (41%) had postoperative hypocalcemia. Eight patients (12%) had hypocalcemia at 6 mo. Risk factors for hypoparathyroidism at 6 mo were a cancer diagnosis (odds ratio [OR] 6.7; P = 0.02), CLND (OR 12.6; P < 0.01), and parathyroid tissue in the surgical specimen on pathologic analysis (OR 19.5; P < 0.01). Only two patients (3%) developed permanent hypoparathyroidism, both of whom had thyroidectomy for cancer and underwent CLND. CONCLUSIONS:Children with thyroid cancer are at high risk for postoperative hypocalcemia after total thyroidectomy. The risk is further increased by CLND, which should be performed selectively. A majority of patients with hypoparathyroidism at 6 mo postoperatively regain normal parathyroid function by 1 y. Permanent hypoparathyroidism in children after total thyroidectomy at a pediatric endocrine surgery center is rare.

摘要

背景: 甲状旁腺功能减退症引起的术后低钙血症是儿童甲状腺全切除术最常见的并发症。我们假设大多数术后低钙血症的儿童在 12 个月前会出现尿尿,并试图确定永久性甲状旁腺功能减退的危险因素。 方法: 我们回顾性分析了 2012年-2019年在一家儿童医院接受甲状腺全切除术的儿童。既往颈部手术的患者被排除在外。记录手术指征、最终病理诊断和术后 12 个月的血钙。永久性甲状旁腺功能减退被定义为术后超过 1 y 的补充钙需要量。 结果: 68 例患者行甲状腺全切除术。Graves 病是最常见的良性手术指征 (38 例患者)。26 例患者 (38%) 在最终病理中患有癌症。12 例癌症患者行中央区淋巴结清扫术 (CLND)。28 例 (41%) 患者术后出现低钙血症。8 例 (12%) 患者在 6 个月时出现低钙血症。6 个月时甲状旁腺功能减退的危险因素是癌症诊断 (比值比 [OR] 6.7; P = 0.02) 、 CLND (OR 12.6; P < 0.01) 、病理分析手术标本中的甲状旁腺组织 (OR 19.5; P <0.01)。只有 2 例患者 (3%) 发生永久性甲状旁腺功能减退,两例患者均因癌症行甲状腺切除术并接受 CLND。 结论: 甲状腺癌患儿全甲状腺切除术后低钙血症的风险较高。风险进一步增加 CLND,应选择性地进行。大多数甲状旁腺功能低下患者在术后 6 mo 恢复正常甲状旁腺功能 1 y。小儿内分泌外科中心甲状腺全切除术后儿童永久性甲状旁腺功能减退罕见。

METHODS:OBJECTIVES:To assess the prevalence of Hashimoto thyroiditis (HT) in primary thyroid lymphoma (PTL) and whether it differs between mucosa-associated lymphoid tissue (MALT) lymphoma and diffuse large B-cell lymphoma (DLBCL). METHODS:Electronic databases were searched for studies assessing HT prevalence in PTL, based on antithyroid antibodies, clinical history, or pathology. Pooled prevalence of HT and its association with histotype (MALT or DLBCL) were calculated. RESULTS:Thirty-eight studies with 1,346 PTLs were included. Pooled prevalence results were 78.9% (any HT evidence), 65.3% (antithyroid antibodies), 41.7% (clinical history), and 64% (pathology). HT prevalence was significantly higher in MALT lymphoma than in DLBCL (P = .007) and in mixed DLBCL/MALT than in pure DLBCL (P = .002). CONCLUSIONS:Overall, 78.9% of patients with PTL have any HT evidence, but only half of these had been clinically followed. The difference in HT prevalence suggests that a subset of DLBCL may not derive from MALT lymphoma.

METHODS:Background Whether chronic lymphocytic thyroiditis (CLT) influences the risk of development and the progression of papillary thyroid cancer (PTC) remains uncertain. We investigated the effects of CLT on the clinicopathologic features and prognosis of PTC. Methods Two thousand nine hundred twenty-eight consecutive patients with PTC treated between 2009 and 2017 were divided into two groups: one with chronic lymphocytic thyroiditis and one without; 1174 (40%) of the patients had coincident CLT. Results In univariate analysis, CLT correlated positively with small tumor size, frequent extrathyroidal extension, multifocal diseases, and p53 but negatively with central lymph node (LN) metastasis and BRAF mutation. In multivariate analysis, CLT was associated with extrathyroidal extension and multifocal disease; however, it was not a prognostic factor for recurrence even though it was associated with two aggressive factors. Compared with patients with PTC alone, there were more retrieved central LNs in the PTC + CLT group, and these patients also underwent more invasive diagnostic tests such as fine needle aspiration cytology and frozen biopsy of LN. Conclusions The CLT patients with PTC had better behavior features and prognoses than did those with PTC alone despite frequent multifocality and extrathyroidal extension. However, precaution may be necessary to avoid performing invasive diagnostic procedures for lateral LN metastasis and to manage the patients appropriately.

METHODS::PTPN2 is one of the members of the protein Tyrosine Phosphatases (PTPs) family. To explore the promotive effect of upregulated PTPN2 induced by inflammatory response or oxidative stress on the progression of thyroid cancer. PTPN2 level in thyroid cancer tissues and cell lines was detected. Kaplan-Meier method was applied for evaluating the prognostic value of PTPN2 in thyroid cancer patients. After stimulation of inflammatory response (treatment of IFN-γ and TNF-α), or oxidative stress (treatment of H2O2), protein level of PTPN2 in K1 cells was measured by Western blot. Regulatory effects of PTPN2 on EdU-positive staining and Ki-67 positive cell ratio in K1 cells either with H2O2 stimulation or not were determined. PTPN2 was upregulated in thyroid cancer tissues and cell lines. Its level was higher in metastatic thyroid cancer patients than those of non-metastatic ones. High level of PTPN2 predicted worse prognosis of thyroid cancer. Treatment of either IFN-γ or TNF-α upregulated protein level of PTPN2 in K1 cells. Meanwhile, H2O2 stimulation upregulated PTPN2, which was reversed by NAC administration. With the stimulation of increased doses of H2O2, EdU-positive staining and Ki-67 positive cell ratio were dose-dependently elevated. Silence of PTPN2 attenuated proliferative ability and Ki-67 expression in K1 cells either with H2O2 stimulation or not. Inflammatory response or oxidative stress induces upregulation of PTPN2, thus promoting the progression of thyroid cancer.
