概括
胃肠道 stromal 瘤 (GIST) 治疗由于突变而面临抗药性. 新的疗法针对这些突变和耐药性机制进行先进的GIST管理.
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:
- 大多数胃肠道 stromal 瘤 (GIST) 是通过激活 Proto-oncogene c-KIT (KIT) 或 PDGFRA 受体氨酸激酶 (RTK) 的突变驱动的.
- 伊马替尼,一种氨酸激酶抑制剂 (TKI),彻底改变了先进的GIST管理,但通过二次突变在2年内出现了耐药性.
- 一些患者出现了新的抗药性,包括具有PDGFRA外因子18突变或缺乏KIT/PDGFRA突变的患者.
结论:
- 高级GIST的有效管理需要解决原发性突变和获得性耐药性机制.
- 目前正在进行的临床试验对于评估针对抗性GIST的新疗法策略至关重要.
- 未来的方向涉及组合疗法和针对表观遗传修饰以改善GIST结果.

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
3.4K
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...

Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
