概括
在手术前,在乳头甲状腺癌 (PTC) 患者中,循环瘤细胞 (CTC) 普遍存在. 甲状腺切除术后,CTC数量下降,表明液体活检.
科学领域:
- 在瘤学瘤学.
- 分子诊断学 分子诊断
- 手术瘤学手术瘤学
背景情况:
- 乳头甲状腺癌 (PTC) 是一种常见的内分泌恶性瘤.
- 在PTC中评估外科治疗疗效通常需要侵入性方法.
- 循环瘤细胞 (CTC) 是一种潜在的非侵入性生物标志物.
研究的目的:
- 调查PTC患者中CTC的患病率和亚型分布.
- 为了评估甲状腺切除术前后的CTC计数变化.
- 确定CTC计数是否可以作为PTC中外科疗效的非侵入性标记.
主要方法:
- 62名接受甲状腺切除术的PTC患者的前性评估.
- 外周血液样本采集于手术前,手术后2周和3个月.
- 使用负选择和免疫光染色进行表型分类的CTC分析 (表皮,表皮-介质细胞,介质细胞).
主要成果:
- 在87%的患者中检测到手术前的CTC,其中介质细胞/表皮细胞-介质细胞表型占主导地位.
- 甲状腺切除术后的平均CTC计数显著下降 (从8.0到5.3在2周,4.3在3个月).
- 在患有淋巴侵袭,淋巴结转移或BRAF V600E突变的患者中,术后的CTC减少更为显著.
结论:
- 在PTC中经常检测到CTC,显著的比例经历了上皮细胞-介质细胞过渡.
- 甲状腺切除术后CTC计数显著下降表明手术干预成功.
- 通过液体活检检测CTC显示承诺作为一个非侵入性工具监测PTC手术治疗疗效.

Metastasis
5.5K
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

The Tumor Microenvironment
6.6K
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...
