概括
卢克索利提尼布 (RUX) 的使用并没有增加患有骨髓增殖性瘤 (MPNs) 的老年患者出现第二次原发性恶性瘤 (SMs) 的风险. 这项研究发现,RUX用户和非用户之间的SM发展没有显著差异.
科学领域:
- 血液学 血液学 血液学
- 在瘤学瘤学.
- 药理学 药理学是指药理学的学科.
背景情况:
- 骨髓增殖性瘤 (MPNs),包括真多细胞血症 (PV),基本血栓细胞血症 (ET) 和骨髓纤维化 (MF),与第二次原发性恶性瘤 (SMs) 的风险增加有关.
- 尽管已知与非黑色素瘤皮肤癌的相关性,但在SMs,特别是固体和淋巴细胞癌的发展中,如 ruxolitinib (RUX) 等疗法的作用仍然是研究的主题.
研究的目的:
- 评估鲁克索利提尼布 (RUX) 使用与在老年患者中诊断出骨髓增殖性瘤 (MPNs) 的第二次原发性恶性瘤 (SMs) 的发生率之间的关联.
- 为了确定RUX是否会影响这种患者群体中发展固体或淋巴性SM的风险.
主要方法:
- 从2012年到2019年使用监测,流行病学和最终结果-医疗保险相关数据库进行了回顾性队列分析.
- 数据包括6043名患者 (2396名PV,2944名ET,703名MF),平均年龄为76岁,比较了513名RUX用户和5530名非用户.
- 采用多变量比例分区危险回归模型,将死亡作为竞争风险.
主要成果:
- 在RUX使用者和非使用者 (HR,0.96;95%CI,0.65-1.42;P = .84) 之间没有观察到任何SM发展的总体风险的显著差异.
- 暴露于RUX并没有显著影响固体SM (HR,0.77;95% CI,0.48-1.23;P = .27) 或淋巴性SM (HR,1.73;95% CI,0.79-3.80;P = .17) 的风险.
- 此外,RUX所覆盖的日数比例也与MS发展风险无关.
结论:
- 卢克索利提尼布 (RUX) 的使用似乎不会增加患有骨髓增殖性瘤 (MPNs) 的老年患者出现第二次原发性恶性瘤 (SMs) 的风险.
- 这些发现表明,RUX可以在没有对该特定患者群体中二次癌症发展的高度担忧的情况下使用.

Rous Sarcoma Virus (RSV) and Cancer
6.1K
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.

Treatment Resistant Cancers
3.7K
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...

Abnormal Proliferation
5.1K
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...

Targeted Cancer Therapies
8.6K
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.

mTOR Signaling and Cancer Progression
4.6K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

Non-LTR Retrotransposons
13.1K
As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...
