まとめ
高リスクの非転移性患者では,毎日のアスピリンは乳がんの再発や生存率を改善しませんでした. アスピリンは,この研究で効果がないため,乳がん治療の補助剤として推奨されません.
科学分野:
- 腫瘍学
- 臨床試験
- 薬理学について
背景:
- 観察研究ではアスピリンは乳がんの生存率を向上させることが示唆されています.
- 乳がんの再発予防のためのアスピリンの将来性研究は限られている.
研究 の 目的:
- 乳がんの生存者においてアスピリンが侵襲性がんのリスクを軽減するかどうかを判断する.
- 乳がんの再発を予防するアスピリンの有効性を評価する.
主な方法:
- 高リスクの非転移性乳がん患者3020人を対象に,ランダム化,プラセボ対照のダブルブラインド試験 (NCT02927249) を実施した.
- 参加者は毎日300mgのアスピリンまたはプラセボを5年間服用しました.
- 主要結果:侵襲性疾患のない生存 副次結果:全生存
主要な成果:
- 暫定分析の無効性により,研究を早期に中止しました.
- アスピリンは侵襲性疾患の生存率を有意に改善しなかった (HR,1.27;P=.06).
- アスピリン群では数値的に高い侵襲的な事件と,全生存率の違いは観察されなかった.
結論:
- 高リスクの非転移性乳がん患者では,毎日のアスピリンの治療で乳がんの再発リスクや生存率が改善されなかった.
- アスピリンは乳がんの補助治療として推奨されません.
- 特定のサブグループでの潜在的利益を探るにはさらなる研究が必要かもしれません.

Antiplatelet Drugs: Prostaglandin Synthesis, P2Y12 and Glycoprotein IIb/IIIa Inhibitors
522
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.

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.

Adrenergic Agonists: Therapeutic Classification
775
Adrenergic agonists can be classified based on their therapeutic uses and mechanisms of action. They serve various purposes in clinical applications.
Vasopressor or pressor agents: They increase blood pressure and function as cardiac stimulants. Examples include endogenous catecholamines (norepinephrine and dopamine) and synthetic agents (phenylephrine).
Bronchodilators: β2-agonists can relax bronchial muscles and widen airways. They are commonly used for treating obstructive pulmonary...
