概括
清细胞癌 (ccRCC) 通常与希佩尔-林道基因突变有关,通过缺氧诱导因素和VEGF驱动瘤生长. 尽管有抗血管性和免疫疗法,ccRCC仍然难以治疗,需要进一步研究.
科学领域:
- 在瘤学瘤学.
- 分子生物学分子生物学
- 癌症研究 癌症研究
背景情况:
- 清细胞癌 (ccRCC) 在全球约占癌的80%.
- 大多数ccRCC病例都涉及到希佩尔-林道基因 (VHL) 中的失活突变.
- VHL基因突变导致低氧诱导因子 (HIF) 的稳定,通过血管内皮生长因子 (VEGF) 的过度表达促进血管生成.
研究的目的:
- 审查目前对ccRCC生物学的理解,重点关注VHL基因突变和VEGF的作用.
- 讨论用于ccRCC的现有抗血管生成疗法 (AAT) 和免疫检查点抑制剂 (ICI).
- 强调需要进一步研究ccRCC病理生理学和耐药机制,以开发新疗法.
主要方法:
- 关于ccRCC遗传学,血管新生和治疗方式的文献综述.
- 对参与ccRCC发展的分子途径的分析,包括VHL-HIF-VEGF轴.
- 检查当前的治疗策略,如抗VEGF疗法,氨酸激酶抑制剂和免疫检查点抑制剂.
主要成果:
- VHL基因失活是ccRCC的关键驱动因素,导致VEGF增加并促进瘤血管化.
- 目前的治疗方法包括抗血管原剂 (例如,VEGF抑制剂,TKIs) 和免疫检查点抑制剂 (抗PD-1,抗PD-L1,抗CTLA-4).
- 在瘤微环境中,VEGF和VEGFC在血管生成,淋巴血管生成和免疫逃避中发挥作用.
结论:
- 尽管在抗血管性和免疫疗法方面取得了进展,ccRCC仍然是一个具有挑战性的恶性瘤,有效治疗.
- 了解瘤微环境和抵抗机制对于开发改进的ccRCC疗法至关重要.
- 进一步的研究对于发现癌治疗的新治疗点和策略至关重要.

493
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.

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.

Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...

02:50Combination Therapies and Personalized Medicine

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...

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
