概括

针对BRAF-V600突变非小细胞肺癌 (NSCLC) 的一线向治疗或免疫瘤学 (IO) 产生类似的生存率. 患者的性别和PD-L1状态可以指导治疗决策.

科学领域:

在瘤学瘤学.
基因组学就是基因组学.
免疫治疗是一种免疫疗法.

背景情况:

用BRAF/MEK抑制剂治疗BRAF-V600突变非小细胞肺癌 (NSCLC) 是有效的,但面临抗药性.
免疫检查点抑制 (IO) 在BRAF突变NSCLC中提供潜在的长期益处.
对于BRAF突变NSCLC的最佳一线治疗序列仍然没有定义.

研究的目的:

调查转移性BRAF-V600突变NSCLC的第一线治疗的临床结果.
为了比较向疗法的疗效与基于IO的疗法.
确定影响治疗反应的因素,包括患者的性别和PD-L1状态.

主要方法:

对205名转移性BRAF-V600突变NSCLC患者的回顾性分析.
评估一线治疗方法,包括达布拉费尼布/特拉美丁尼布 (DAB/TRM),单独的IO和化疗-IO.
评估整体存活 (OS) 和治疗时间失败 (TTF).

主要成果:

第一线DAB/TRM和化疗-IO显示相同的中位 OS (28.0 vs 27.8 个月).
女性患者表现出优异的OS,特别是第一线DAB/TRM (OS HR 0.53).
高PD-L1状态 (≥50%) 与缩短的TTF相关,无论治疗类型如何.

Tumor Immunotherapy

Tumor Immunotherapy

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.

Combination Therapies and Personalized Medicine

Combination 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...

Targeted Cancer Therapies

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.
There are several types of targeted therapies against...

Cancer Vaccines

Cancer Vaccines

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...

Cancer Therapies

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...
