概括
复发性头角状细胞癌 (HNSCCs) 的遗传分析显示,瘤多样性增加,免疫细胞存在性降低. 重复活检对于在复发性HNSCC时选择有效的治疗方法至关重要.
科学领域:
- 在瘤学瘤学.
- 基因组学就是基因组学.
- 免疫学 免疫学 免疫学
背景情况:
- 头部和部状细胞癌 (HNSCCs) 在起源和病因学方面呈现异质性.
- 了解从诊断到复发和进展的遗传进化对于治疗选择至关重要,特别是针对性疗法和免疫疗法.
研究的目的:
- 与原发性瘤相比,研究复发性HNSCC中的基因组和转录组变化.
- 评估这些变化对瘤多样性和免疫微环境的影响.
主要方法:
- 来自9名患者的初级和复发性HNSCC样本的整体外体序列测序和转录组分析.
- 在PhenoCycler平台上使用多重免疫光 (IF) 分析突变特征和免疫细胞存在.
主要成果:
- 复发性瘤获得了新的突变,并保持了一些来自初级瘤的突变,从而增加了基因多样性.
- 与初级瘤相比,复发样本显示免疫细胞透率降低和免疫反应基因的下调.
- 突变特征也在初级和复发的HNSCC之间演变.
结论:
- 分析每个患者的多个样本,可以全面了解瘤的演变.
- 建议在复发或治疗失败时进行再活检,以指导HNSCC的最佳治疗策略.

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...

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...
