概括

多焦点 papillary 甲状腺癌 (MPTC) 主要是由内腺转移引起的,而不是独立的起源. 这种转移形式显示出更大的侵入性,这表明需要对MPTC患者采取积极的,个性化的治疗策略.

科学领域:

在瘤学瘤学.
遗传学遗传学是一个
病理学病理学病理学

背景情况:

多焦点乳头甲状腺癌 (MPTC) 在确定多重甲状腺瘤的克隆起源方面存在挑战.
了解MPTC的起源对于有效的诊断和治疗计划至关重要.

研究的目的:

通过使用双基因和蛋白质检测来研究MPTC的克隆起源和生物行为.
区分MPTC的内腺转移和独立的多中心起源.

主要方法:

研究了52名MPTC患者使用免疫组织化学检测BRAF和TERT蛋白表达.
使用定量PCR和桑格测序来检测BRAF和TERT基因突变.
将MPTC病例分为内腺转移 (71.2%) 和独立多中心起源 (28.8%) 的两组.

主要成果:

在内腺转移组中,BRAF蛋白表达和基因突变显著更高.
两组之间没有发现TERT蛋白或基因状态的显著差异.
与多中心起源相比,内腺转移性MPTC显示出侵入性增加,侧淋巴结转移率更高,瘤囊入侵率更高.

结论:

MPTC最常见的结果是内腺转移,表明瘤行为更具侵略性.
内腺转移性MPTC与更高的侵入性和病原性基因变异有关.
强烈的和个性化的手术和后续策略建议用于内腺转移的MPTC.

Tumor Progression

Tumor Progression

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
