概括
隐性乳腺癌 (OBC) 呈现为淋巴结转移而没有原发性瘤. 最终的病态淋巴结阶段是这些病例中复发的关键预测因素.
科学领域:
- 在瘤学瘤学.
- 病理学 病理学 病理学
- 放射学 放射学是一门学科.
背景情况:
- 隐性乳腺癌 (OBC) 诊断时,乳腺癌转移到下淋巴结,而没有乳腺中可检测的原发性瘤.
- 以前对OBC的研究主要集中在治疗策略上.
研究的目的:
- 研究隐性乳腺癌的临床,形态和免疫组织化学特征.
- 确定与OBC患者复发相关的预后因素.
主要方法:
- 在1996年至2021年期间,对68名被诊断患有OBC的患者进行了回顾性分析.
- 纳入标准:经过活检证明的状转移性乳腺癌和非贡献性乳房影像/超声波后的MRI.
- 排除标准:之前有乳腺癌史.
主要成果:
- 大多数OBC (81%) 差异化很差,没有特殊类型 (管道) 癌.
- 免疫组织化学亚型包括激素受体阳性 (57.4%),HER2阳性 (33.3%) 和三阴性 (22.8%).
- 最终的病态淋巴结阶段是复发的唯一显著预测因素 (P<0.001).
结论:
- OBC表现出多样化的形态和免疫组织化学特征.
- 病理性淋巴结分期对预测隐性乳腺癌复发风险至关重要.
- 对OBC最佳管理策略的进一步研究是有必要的.

7.7K
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 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...
