概括
双重免疫检查点抑制剂 (IOIO) 和免疫检查点抑制剂加氨酸激酶抑制剂 (IOTKI) 在转移性细胞癌 (mRCC) 中的存活率相似. 像骨转移和BMI这样的患者因素可能会指导个性化的IOIO或IOTKI选择.
科学领域:
- 在瘤学瘤学.
- 免疫治疗是一种免疫疗法.
- 细胞癌研究 细胞癌研究
背景情况:
- 组合疗法,包括免疫检查点抑制剂,已经改变了转移性细胞癌 (mRCC) 的第一线治疗方法.
- 双重免疫检查点抑制剂 (IOIO) 和免疫检查点抑制剂加氨酸激酶抑制剂 (IOTKI) 之间的直接比较临床试验数据有限.
- 这种缺乏数据在选择基于个体患者资料的最佳第一线mRCC治疗时造成不确定性.
研究的目的:
- 为了比较双重免疫检查点抑制剂 (IOIO) 与免疫检查点抑制剂加氨酸激酶抑制剂 (IOTKI) 在mRCC的第一线治疗中的疗效.
- 为了确定可能影响IOIO和IOTKI治疗方案之间的治疗结果的患者特异性因素.
主要方法:
- 在171名mRCC患者的数据上使用治疗权重的逆概率 (IPTW) 分析.
- 评估无进展生存率 (PFS) 和总生存率 (OS) 作为主要终点.
- 根据患者特征进行子组分析,以探索基于患者特征的不同治疗效果.
主要成果:
- 在整体IPTW队列中,IOIO和IOTKI之间没有观察到PFS或OS的显著差异.
- 在没有骨转移的患者中,IOTKI治疗证明了改善PFS和OS.
- 在BMI>25的患者中,IOTKI与更好的生存状况相关,而IOIO在BMI<18.5.5的患者中显示出更好的生存状况.
结论:
- IOIO和IOTKI都是对mRCC的有效一线治疗方法.
- 患者的特征,包括骨转移和体重指数 (BMI) 的存在,对于定制治疗选择至关重要.
- 这项研究支持针对mRCC的个性化治疗策略,通过将患者与最合适的组合疗法相匹配来优化治疗结果.

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
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
488
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.

Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...

Cancer Therapies
7.6K
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...
