概括
LEN-TAP疗法显著改善了救援肝脏切除率和在不可切除的肝细胞癌 (uHCC) 中的客观反应. 这种组合疗法对HHCC转化有前途,特定的T细胞预测治疗成功.
科学领域:
- 肝胆瘤学 肝胆瘤学
- 翻译癌症研究 翻译癌症研究
- 免疫治疗是一种免疫疗法.
背景情况:
- 不切除的肝细胞癌 (uHCC) 具有有限的治疗选择,转化疗法的有效性往往未被证明.
- 目前对HHCC的现有策略缺乏可靠的证据,需要新的治疗方法.
- 作为一种潜在的转化疗法,LEN-TAP疗法 (伦瓦蒂尼布,跨动脉化学栓塞,PD-1抑制剂) 正在研究中.
研究的目的:
- 为了比较LEN-TAP疗法的疗效和安全性,单独对抗非切除性肝细胞癌 (uHCC) 的患者的跨动脉化学血栓化 (TACE).
- 评估救援肝切除率 (SLR) 的主要结果和二次结果,包括客观反应率 (ORR),整体存活率 (OS),无事件存活率 (EFS),无复发存活率 (RFS) 和安全.
- 探索预测治疗反应的潜在生物标志物.
主要方法:
- 一项前性,第二阶段的多中心试验 (NCT04997850) 招募了142名符合条件的HHC患者.
- 参与者被随机分配到接受LEN-TAP疗法 (n=71) 或TACE单疗法 (n=71).
- 探索性分析包括单细胞测序和流细胞测量,以评估免疫细胞群和信号通路.
主要成果:
- 与TACE单独治疗相比,LEN-TAP队列的SLR率 (59.2%与18.3%,P<0.001) 和ORR (78.9%与16.9%,P<0.001) 显着更高.
- 在LEN-TAP组中,中位数的OS,EFS和RFS显著延长 (分别未达到与23.0个月,P<0.001;20.03与6.52个月,P<0.001;36.6与19.0个月,P=0.048).
- 与治疗相关的3级不良事件在LEN-TAP治疗中更频繁 (60.6%对21.1%,P<0.001),但没有观察到4级或更高毒性. 循环中的HLA-DR+CD38+CD8+T细胞增加与反应改善相关.
结论:
- 该LEN-TAP协议显示显著的承诺作为一个有效的转换治疗不可切除的肝细胞癌 (uHCC),改善关键的瘤结果.
- 该疗法与可接受的耐受性有关,尽管3级不良事件的发病率较高.
- 循环中的HLA-DR+CD38+CD8+T细胞可以作为接受LEN-TAP治疗的HHCC患者治疗反应的预测生物标志物.

Other than maintaining genome stability via DNA repair, homologous recombination plays an important role in diversifying the genome. In fact, the recombination of sequences forms the molecular basis of genomic evolution. Random and non-random permutations of genomic sequences create a library of new amalgamated sequences. These newly formed genomes can determine the fitness and survival of cells. In bacteria, homologous and non-homologous types of recombination lead to the evolution of new...

Predicting Products: SN1 vs. SN2
15.9K
Nucleophilic substitution reactions of alkyl halides can proceed via an SN1 or an SN2 mechanism. While in SN2 reactions, the nucleophile attacks the substrate simultaneously as the leaving group departs, in SN1 reactions, the substrate first dissociates to give the carbocation intermediate. Various factors such as the structure of the substrate, the strength of the nucleophile, and the nature of the solvent promote one mechanism over the other.

Drug Administration and Therapy Phases: Overview
1.3K
Drugs, the chemical agents used in diagnosing, treating, or preventing diseases, undergo a four-phase process of development: pharmaceutic, pharmacokinetics, pharmacodynamics, and therapeutic.
The pharmaceutical phase focuses on leveraging the physicochemical properties of the drug to design and manufacture an effective product. Variants include orally administered tablets or capsules, topical creams or ointments, and parenteral-delivery solutions or emulsions.

Disassembly of Intermediate Filaments
2.6K
Intermediate filaments (IFs) do not undergo spontaneous disassembly. Enzymes, kinases, and phosphatases add and remove phosphates from specific sites to regulate their disassembly. The IF concentration in the cytoplasm also regulates the disassembly. If the concentration crosses a threshold, it activates the protein kinases in the vicinity, allowing the phosphorylation of IFs.

Types of Intermediate Filaments
4.8K
The intermediate filaments are an essential component of the cytoskeleton. Presently six types of intermediate filament have been identified. Type I and II are acidic and basic keratin proteins. Type III is of mesodermal origin and comprises four proteins: vimentin, desmin, glial fibrillary acidic protein (GFAP), and peripherin. Vimentin is commonly found in mesenchymal cells, desmin in muscle cells, GFAP in astrocytes, while peripherin is found in peripheral nervous system neurons (PNS). Type...
