Hürthle cell carcinoma (HCC) is a distinct type of thyroid cancer genetically characterized by DNA copy number alterations (CNA), typically of genome haploidization type (GH-type). However, whether CNA also occurs in benign Hürthle cell adenomas (HCA) or Hürthle cell hyperplastic nodules (HCHN), and have diagnostic impact in fine-needle aspiration (FNA) samples, remains unknown. To address these questions, we (1) analyzed 26 HCC, 24 HCA, and 8 HCHN tissues for CNA and other mutations using ThyroSeq v3 (TSv3) next-generation sequencing panel, and (2) determined cancer rate in 111 FNA samples with CNA and known surgical outcome. We identified CNA, more often of the GH-type, in 81% of HCC and in 38% HCA, but not in HCHN. Among four HCC with distant metastasis, all had CNA and three TERT mutations. Overall, positive TSv3 results were obtained in 24 (92%) HCC, including all with ATA high risk of recurrence or metastasis. Among 111 FNA cases with CNA, 38 (34%) were malignant and 73 (66%) benign. A significant correlation between cancer rate and nodule size was observed, particularly among cases with GH-type CNA, where every additional centimeter of nodule size increased the malignancy odds by 1.9 (95% CI 1.3-2.7; P = 0.001). In summary, the results of this study demonstrate that CNA characteristic of HCC also occur in HCA, although with lower frequency, and probability of cancer in nodules with CNA increases with nodule size. Detection of CNA, in conjunction with other mutations and nodule size, is helpful in predicting malignancy in thyroid nodules.

Hürthle 细胞结节的分子改变和术前癌症风险。

Hürthle 细胞癌 (HCC) 是一种独特类型的甲状腺癌,其遗传特征为 DNA 拷贝数改变 (CNA),通常为基因组单倍体化类型 (GH 型)。然而,CNA 是否也发生在良性 Hürthle 细胞腺瘤 (HCA) 或 Hürthle 细胞增生性结节 (HCHN) 中,并且对细针抽吸 (FNA) 样本有诊断影响,仍然未知。为了解决这些问题,我们 (1) 使用 ThyroSeq v3 (TSv3) 下一代测序面板分析了 26 个 HCC、24 个 HCA 和 8 个 HCHN 组织的 CNA 和其他突变,以及 (2) 使用 CNA 确定了 111 个 FNA 样本中的癌症发生率和已知的手术结果。我们在 81% 的 HCC 和 38% 的 HCA 中发现了 CNA,通常是 GH 型,但在 HCHN 中没有。在 4 例远处转移的 HCC 中,均具有 CNA 和 3 处 TERT 突变。总体,在 24 例(92%)HCC 中获得了阳性 TSv3 结果,包括所有具有复发或转移高风险的 ATA。在 111 例 CNA 的 FNA 病例中,38 例(34%)为恶性,73 例(66%)为良性。观察到癌症发病率与结节大小之间存在显着相关性,特别是在 GH 型 CNA 病例中,结节大小每增加一厘米,恶性肿瘤几率增加 1.9(95% CI 1.3-2.7;P = 0.001)。总之,这项研究的结果表明,HCC 的 CNA 特征也发生在 HCA 中,尽管频率较低,并且 CNA 结节的癌症概率随着结节大小而增加。CNA 的检测,连同其他突变和结节大小,有助于预测甲状腺结节的恶性程度。38 例(34%)为恶性,73 例(66%)为良性。观察到癌症发病率与结节大小之间存在显着相关性,特别是在 GH 型 CNA 病例中,结节大小每增加一厘米,恶性肿瘤几率增加 1.9(95% CI 1.3-2.7;P = 0.001)。总之,这项研究的结果表明,HCC 的 CNA 特征也发生在 HCA 中,尽管频率较低,并且 CNA 结节的癌症概率随着结节大小而增加。CNA 的检测,连同其他突变和结节大小,有助于预测甲状腺结节的恶性程度。38 例(34%)为恶性,73 例(66%)为良性。观察到癌症发病率与结节大小之间存在显着相关性,特别是在 GH 型 CNA 病例中,结节大小每增加一厘米,恶性肿瘤几率增加 1.9(95% CI 1.3-2.7;P = 0.001)。总之,这项研究的结果表明,HCC 的 CNA 特征也发生在 HCA 中,尽管频率较低,并且 CNA 结节的癌症概率随着结节大小而增加。CNA 的检测,连同其他突变和结节大小,有助于预测甲状腺结节的恶性程度。9(95% CI 1.3-2.7;P = 0.001)。总之,这项研究的结果表明,HCC 的 CNA 特征也发生在 HCA 中,尽管频率较低,并且 CNA 结节的癌症概率随着结节大小而增加。CNA 的检测,连同其他突变和结节大小,有助于预测甲状腺结节的恶性程度。9(95% CI 1.3-2.7;P = 0.001)。总之,这项研究的结果表明,HCC 的 CNA 特征也发生在 HCA 中,尽管频率较低,并且 CNA 结节的癌症概率随着结节大小而增加。CNA 的检测,连同其他突变和结节大小,有助于预测甲状腺结节的恶性程度。
