概括

朗格汉斯细胞囊细胞症 (LCH) 是一种由MAPK通路突变驱动的瘤性疾病. 目前的治疗方法对于传播的LCH是不够的,这突显了针对性治疗的必要性.

科学领域:

在瘤学瘤学.
血液学血液学血液学
免疫学免疫学免疫学

背景情况:

朗格汉斯细胞囊炎 (LCH) 是一种骨髓状瘤性疾病,具有多种临床表现,从局部性病变到危及生命的全身性疾病.
目前用于扩散性LCH的标准化疗疗法有效性有限,只有不到50%的患者获得治愈,并存在长期发病风险.
从历史上看,LCH的确切性质一直在争论中,但最近的发现已经确定了激活基因激活蛋白激酶 (MAPK) 路径突变,如BRAFV600E,在髓质前体中作为病变形成的驱动因素.

研究的目的:

审查目前对LCH生物学,临床特征和治疗策略的理解.
讨论理解LCH作为由特定突变驱动的克隆性瘤疾病的范式转变.
通过协调的研究和临床试验努力,确定改善患者治疗结果的机会.

主要方法:

关于LCH病原发生的开创性发现的综述.
分析当前的治疗策略及其局限性.
讨论基础科学发现与临床试验开发之间的翻译差距.

主要成果:

现在LCH被理解为一种由髓质前体中MAPK通路突变驱动的克隆性瘤疾病.
尽管了解病原发生有进展,但目前针对传播性LCH的治疗方法仍然不理想,治疗失败率很高.
对LCH生物学的洞察力为开发合理的,针对突变的治疗方法提供了希望.

结论:

LCH是一种瘤性疾病,而不仅仅是反应性疾病,是由特定的遗传突变驱动的.
迫切需要加快临床试验的开发,以将最近的生物学发现转化为有效的向治疗方法.
在药物优先级和临床试验设计方面的协调努力对于改善所有LCH患者的治疗结果至关重要.

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...

Tumor Progression

Tumor Progression

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Abnormal Proliferation

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...
