概括
免疫检查点抑制在未分化的多形肉瘤 (UPS) 和多纤维肉瘤 (MFS) 中具有前景,但有效性有限. 结合疗法和使用生物标记面板可以改善这些罕见的成人软组织瘤的结果.
科学领域:
- 癌症学
- 免疫疗法
- 癌症研究
背景情况:
- 不分化形肉瘤 (UPS) 和神经纤维肉瘤 (MFS) 是常见的成人软组织肉瘤 (STS).
- 这些亚型具有高度的遗传复杂性,缺乏治疗的特定分子标.
- 免疫检查点抑制 (ICI) 是一种潜在的治疗方法,但其在UPS和MFS中的疗效目前是不理想的.
研究的目的:
- 审查UPS和MFS的临床特征.
- 检查瘤微环境及其对ICI疗效的影响.
- 在UPS和MFS中确定ICI的生物标志物和临床试验.
主要方法:
- 临床特征,TME,生物标志物和临床试验的文献综述.
- 对UPS和MFS的当前和临床前免疫治疗策略的分析.
主要成果:
- 在UPS和MFS的ICI疗效低于其他癌症.
- 结合策略 (ICI + 辐射疗法) 对局部疾病有希望.
- 像三级淋巴体结构 (TLS) 这样的生物标志物正在被调查,但可能需要一个小组方法.
结论:
- 对于先进或不可切割的UPS和MFS,特别是生物标志物,ICI是一个考虑因素.
- 为了准确预测ICI反应,需要生物标志物 (TLS,免疫透,PD-L1) 的组合.
- 对免疫疗法组合和生物标志物的进一步研究对于改善UPS和MFS治疗结果至关重要.

Tumor Immunotherapy
659
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.

Targeted Cancer Therapies

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.

Combination Therapies and Personalized Medicine
5.1K
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

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...
