まとめ
ペムブロリズマブは,パクリタキセルと比較して,進行した胃がんの生存率を有意に改善しませんでした. しかし,ペンブロリズマブは,この患者集団において優れた安全性プロファイルを示した.
科学分野:
- 腫瘍学
- 免疫療法
- 胃腸がん
背景:
- 化学療法で進行した胃と食道関節の癌は 予後が悪い.
- プラチナとフッ素ピリミジンによる第一線化学療法が 標準的な治療法です
研究 の 目的:
- ペムブロリズマブとパクリタキセルの有効性と安全性を比較する.
- PD- L1 CPS ≥ 1 の患者の全生存期および進行性生存期を評価する.
主な方法:
- 30カ国の148センターで実施されたランダム化オープンフェーズ3試験です.
- 患者はペムブロリズマブまたはパクリタキセルを1対1でランダムに割り当てられました.
- 主要エンドポイントは,PD- L1 結合陽性スコア (CPS) が1以上であった患者における全生存率と進行性のない生存率でした.
主要な成果:
- ペムブロリズマブは全生存期間を有意に改善しなかった (9. 1 vs 8. 3ヶ月; HR 0. 82; p=0. 0421).
- 発症しない生存期間はペムブロリズマブより短かった (1. 5 vs 4. 1ヶ月; HR 1.27)
- 治療に関連したグレード3〜5の有害事象は,ペンブロリズマブでは有意に減少した (14%対35%).
結論:
- Pembrolizumabは,PD- L1 CPS ≥1の進行した胃がんにおいて,パクリタキセルに比べて有意な全生存効果を示さなかった.
- ペムブロリズマブはパクリタキセルに比べ,より好ましい安全性プロファイルを示した.
- 胃がんと胃食道がんにおけるペンブロリズマブのさらなる研究が必要である.

Gastric Phase of Digestion
3.4K
The gastric phase of digestion begins as soon as food enters the stomach. The incoming food bolus triggers neural and hormonal mechanisms, which last approximately 3 to 4 hours. During this phase, the stomach undergoes significant changes to prepare the food for further digestion and absorption.
When food enters the stomach, it stretches the stomach walls and activates stretch receptors. This triggers local reflexes of the enteric nervous system, mediated through the myenteric plexus. These...

Phase-lead and Phase-lag Controllers
574
Understanding the working function of different types of controllers can be illustrated with practical analogies, such as adjusting a stereo's volume equalizer. Cranking up the bass involves a phase-lead controller, which functions as a high-pass filter, while increasing the treble uses a phase-lag controller, which acts as a low-pass filter. PD controllers, similar to high-pass filters, enhance the system's response to high-frequency components. PI controllers, akin to low-pass...

Time and frequency -Domain Interpretation of Phase-lead Control
477
Phase-lead controllers are commonly used in various control systems to enhance response speed and stability. Adjusting the brightness on a television screen offers a practical example of phase-lead control. When contrast is enhanced, a phase-lead controller is employed. Mathematically, phase-lead control is identified when the first parameter is smaller than the second.
The design of phase-lead control involves the strategic placement of poles and zeros to balance steady-state error and system...

Time and frequency -Domain Interpretation of Phase-lag Control
422
Phase-lag controllers are widely used in control systems to improve stability and reduce steady-state errors. A dimmer switch controlling the brightness of a light bulb serves as a practical example of phase-lag control, gradually adjusting the bulb's brightness. Mathematically, phase-lag control or low-pass filtering is represented when the factor 'a' is less than 1.
Phase-lag controllers do not place a pole at zero, but instead influence the steady-state error by amplifying any...

Clinical Trials: Overview
5.0K
Clinical development focuses on how the drug will interact with the human body and encompasses four key phases of clinical trials, each serving a specific purpose in assessing the safety and effectiveness of new drugs. These phases overlap and build upon one another. Phase I involves a small group of healthy volunteers (typically 20-80 individuals) or, in cases where significant toxicity is expected, patients with the targeted disease, such as cancer or AIDS. The volunteers are tested for...

Trial and Error and Algorithm
425
A problem-solving strategy is a plan of action used to find a solution. Different strategies have distinct action plans. Trial and error involves trying different solutions until one works. For instance, to fix a broken printer, you might check ink levels, ensure the paper tray isn't jammed, and verify the printer's connection to your laptop. This method can be time-consuming but is commonly used. Thomas Edison, for example, used trial and error to find a suitable filament for the light...
