概括
主要乳腺侵入性导管癌 (IDC) 的正子发射断层扫描/磁共振成像 (PET/MRI) 特性预测转移潜力. 在PET/MRI上,更高的代谢活性和细胞性表明更具侵略性的瘤具有更大的远程传播风险.
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:
- 准确的乳腺侵入性导管癌 (IDC) 阶段确定对于治疗规划至关重要.
- 了解原发性瘤特征和转移性模式之间的关系对于改善患者的治疗结果至关重要.
研究的目的:
- 评估PET/MRI初级瘤成像特征,组织病理特征和新诊断乳腺IDC患者远程转移传播程度之间的关联.
- 为了确定成像参数是否可以提高转移的预测,而不是仅仅与组织病理特征相比.
主要方法:
- 对289名女性乳腺IDC患者的PET/MRI数据的回顾性分析.
- 对原发性瘤代谢参数 (Max SUV,MTV,TLG) 和扩散参数 (ADCmin) 的定量分析.
- 根据转移负担 (非转移性,小转移性,多转移性) 和转移部位 (隔离骨与混合/软组织) 进行患者分类.
主要成果:
- 较高的代谢活性 (MTV,TLG) 和较低的ADCmin值在与非转移性疾病相比,在患有寡头转移和多转移性疾病的患者中观察到.
- 代谢性瘤体积 (MTV) 在寡头转移和多元转移组之间显著差异化.
- PET/MRI参数与侵袭性组织病理特征相关 (3级,ER/PR阴性,HER2阳性,三阴性,高Ki-67).
- 结合成像参数的预测模型在远程转移检测方面表现出优异的分辨能力,与单独的基因病理参数相比.
结论:
- 主要乳腺IDC瘤具有较高的代谢-糖解活性和细胞性,表现出更具侵略性的行为和更大的转移潜力.
- 将PET/MRI成像特征与组织病理学数据相结合,可以更全面地了解乳腺IDC瘤生物学和转移风险.

5.6K
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...

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...

02:53Adaptive Mechanisms in Cancer Cells
5.8K
Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
