概括
对于1-4厘米以上的乳头甲状腺癌 (PTC),2厘米或更小的瘤大小与显著降低侵略性因素的风险有关. 这一发现有助于量身定制较不广泛的手术方法.
科学领域:
- 内分泌学 在内分泌学.
- 手术瘤学手术瘤学
- 病理学 病理学 病理学
背景情况:
- 目前的指导方针建议在乳头甲状腺癌 (PTC) >4厘米的情况下进行全甲状腺切除术.
- 对于PTC>1-4厘米的外科治疗仍在争论中,可能会采用不那么密集的方法.
- 识别PTC>1-4厘米的风险因素对于治疗缓和至关重要.
研究的目的:
- 为了确定PTC中风险因素的流行>1-4厘米.
- 评估原发性瘤大小与风险因素存在之间的关联.
- 为了确定最佳的瘤大小切断界限来识别较低风险的PTC患者.
主要方法:
- 对857名PTC>1-4厘米的患者进行了回顾性分析,这些患者接受了全甲状腺切除术 (2000-2020年).
- 风险因素的评估:血管侵袭,阳性边缘,甲状腺外延伸,侵略性组织学,淋巴结和远程转移.
- 统计分析以将瘤大小与风险因素流行率相关联.
主要成果:
- 不到一半 (47.0%) 的瘤>1-4厘米至少有一个危险因素.
- 瘤大小>2-4厘米与增加的风险因素显著相关 (不包括侵袭性组织学和积极边缘).
- 瘤大小切断值为2.0厘米最好地预测了不良因素的累积风险 (p<0.0001).
结论:
- 瘤小于2.0厘米的PTC患者与瘤≥2.0厘米的患者相比,不良因素的风险几乎降低了两倍.
- 2厘米的切线可以帮助识别高于1-4厘米的大小范围内的低风险PTC患者.
- 这一发现支持基于瘤大小的选择PTC患者的降级手术方法.

02:07Tumor Progression
6.2K
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...

Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.

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...
