概括
在初始诊断时测量的明显扩散系数 (ADC) 可以预测喉平细胞癌 (LSCC) 患者的未来转移. 较低的ADC值与更高的局部和远程转移发病风险有关.
科学领域:
- 在瘤学瘤学.
- 放射学 放射学是一门学科.
- 医疗成像医学成像
背景情况:
- 喉平细胞癌 (LSCC) 是一种常见的头癌.
- 预测LSCC中转移的发展对于治疗计划和患者的治疗结果至关重要.
- 表面扩散系数 (ADC) 是一个量化MRI参数,反映了组织细胞性.
研究的目的:
- 评估ADC对未经治疗的LSCC患者未来转移发展的预测能力.
- 为了确定最初的ADC值是否可以识别具有较高局部或远程转移风险的患者.
主要方法:
- 从37名从未接受过治疗的LSCC患者的MRI扫描进行了回顾性分析.
- 在初始诊断时评估瘤体积和ADC值.
- 随访使用正子发射断层扫描 (PET) 扫描检测转移.
主要成果:
- 在ADC值和局部 (p=0.042) 和远程 (p=0.046) 转移的发展之间发现了显著的关联.
- 随后发生转移的瘤中,平均ADC值明显较低 (p=0.017).
- 还考虑了瘤体积与转移的发展有关.
结论:
- 治疗前的ADC值可以作为预测LSCC未来转移的早期指标.
- ADC测量,以及瘤体积,可以帮助对LSCC患者的风险分层.

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...

Metastasis
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...

Cancer Stem Cells and Tumor Maintenance
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...
