概括
对形淋巴瘤激酶 (ALK) 氨酸激酶抑制剂 (TKI) 的耐药性在非小细胞肺癌 (NSCLC) 中很常见. 针对ALK-TKI耐药性的治疗策略取决于已识别的耐药性机制,而洛拉提尼布是关键选择.
科学领域:
- 在瘤学瘤学.
- 分子生物学分子生物学
- 药理学 药理学是指药理学的学科.
背景情况:
- 无细胞淋巴瘤激酶 (ALK) 基因重组发生在3%至5%的非小细胞肺癌 (NSCLC) 中.
- ALK-氨酸激酶抑制剂 (TKIs) 显著提高了ALK重组NSCLC的存活率.
- 对ALK-TKIs的获得性耐药性是一个主要的挑战,通过ALK依赖和独立的机制导致疾病进展.
研究的目的:
- 审查对第二代ALK-TKI耐药性的机制.
- 概述ALK重组NSCLC患者的临床管理策略,这些患者对第二代ALK-TKI产生耐药性.
主要方法:
- 对第二代ALK-TKI耐药性机制的文献综述.
- 基于耐药性概况的临床管理策略的分析.
主要成果:
- 对第二代ALK-TKI的耐药性可以是ALK依赖的或ALK独立的.
- 洛拉提尼布是对抗第二代ALK-TKI的ALK突变患者的主要治疗选择.
- 特定的耐药性突变 (例如G1202R,L1196M) 引导治疗选择,而洛拉提尼布显示了广泛的覆盖范围.
结论:
- 第二代ALK-TKI衰竭后的治疗策略必须根据抵抗机制量身定制.
- 洛拉提尼布因其广泛的活性而被推用于ALK依赖的抗性突变.
- 对于没有抗药性突变的病例,阿特佐利祖马布,贝瓦齐祖马布和基于的化疗是替代选择.

Targeted Cancer Therapies
7.7K
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

Treatment Resistant Cancers
3.3K
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

Chemotherapy-Induced Nausea and Vomiting: Neurokinin-1 Receptor Antagonists
184
Neurokinin 1 (NK1) receptors are distributed across the GI tract, vagal afferents, and key CNS regions including the central vomiting center and chemoreceptor trigger zone (CTZ) Chemotherapy agents stimulate enterochromaffin cells in the gastrointestinal (GI) tract to release large amounts of substance P (SP). SP is a neuropeptide released by specific sensory nerves in response to many different stressors, including those in the GI mucosa affected by chemotherapy. SP binds and activates...

Combination Therapies and Personalized Medicine
4.9K
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...

Tumor Immunotherapy
551
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
