まとめ
この研究では,BRCA2変異が,ポリアドプリボースポリメラーゼ阻害剤 (iPARP) を服用している卵巣がん患者における静脈および動脈性血栓塞栓症 (VTE/ AT) の予測因子であることが判明しました. ベバシズマブはVTE/ ATのリスクを軽減する.
科学分野:
- 腫瘍学
- トロンボシス 研究
- 薬用警戒について
背景:
- 卵巣がん患者には,ポリー- ADP- リボースポリメラーゼ阻害剤 (iPARP) を投与すると,血栓塞栓症の危険性があります.
- これらの出来事を予測する要因を特定することは,患者の管理に極めて重要です.
研究 の 目的:
- iPARP治療を受けている卵巣がん患者における静脈および動脈性血栓塞栓症 (VTE/ AT) の発生率を決定する.
- VTE/ATの予測要因を特定し,これらのイベントが全生存期に与える影響を評価する.
主な方法:
- iPARPで治療された329人の卵巣がん患者による多中心治験.
- 分析には,予測要因のロジスティック回帰と生存結果のKaplan- Meier分析が含まれていました.
主要な成果:
- VTE/ ATの発生率は4. 9%でした.
- BRCA2変異は,有意にVTE/ ATリスクの増加と関連していた (56. 3% vs 19. 2%; p < 0. 001).
- 併用ベバシズマブ治療は,血栓形成に対する保護効果を示した (OR: 0. 262; p = 0. 010).
結論:
- BRCA2変異は,iPARPを服用している卵巣がん患者のVTE/ ATの重要な予測因子です.
- ベバシズマブは血栓的事件のリスクを減らすことができますが,バイアスは可能です.
- 研究結果は,臨床試験における血栓予防戦略にインパクトを与える.

Targeted Cancer Therapies
7.8K
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
3.9K
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.

Antiplatelet Drugs: Prostaglandin Synthesis, P2Y12 and Glycoprotein IIb/IIIa Inhibitors
642
Antiplatelet drugs emerge as frontline defenders against the insidious threat of thromboembolic diseases, where abnormal clots obstruct vital blood vessels. These drugs stand as bulwarks, inhibiting platelet aggregation and clot formation, thereby mitigating the risk of life-threatening conditions like myocardial infarction, coronary artery disease, and thrombotic strokes.

Chemotherapy-Induced Nausea and Vomiting: 5-HT3 Receptor Antagonists
321
5-HT3 receptor antagonists, such as dolasetron, granisetron (Kytril), ondansetron (Zofran), and palonosetron (Axoli), are crucial in managing chemotherapy-induced nausea and vomiting (CINV) and postoperative nausea. These drugs selectively block 5-HT3 receptors in the visceral vagal and spinal afferent nerves, chemoreceptor trigger zone, and the vomiting center. They have a rapid onset of action and can be given as a single dose before chemotherapy. Ondansetron and granisetron, in particular,...
