科学领域:

血液学血液学血液学
在瘤学瘤学.
基因组学就是基因组学.

背景情况:

抗化学疗法和复发是治疗T细胞急性淋巴细胞白血病 (T-ALL) 的关键挑战.
瘤异质性是T-ALL治疗失败的可疑驱动因素,但特定的细胞和遗传因素仍然不清楚.
了解这些因素对于开发针对高风险T-ALL的向治疗至关重要.

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...
