- 基于证据的医学是基于证据的医学.
背景情况:
- 质母细胞瘤 (GB) 是最具侵略性的原发性脑瘤,预后不佳.
- 新诊断的GB存在标准治疗方法,但对于渐进的GB缺乏共识.
- 目前正在研究针对GB的高级阶段的向疗法.
研究的目的:
- 系统地分析随机对照试验 (RCT),评估针对渐进性GB的向药物.
- 为治疗渐进性质母细胞瘤制定基于证据的建议.

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.

Treatment Resistant Cancers
Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...
