まとめ
グラスゴー予後スコア(GPS)および栄養予後指数(PNI)は、広範期小細胞肺癌(ES-SCLC)患者の転帰を予測する。好中球リンパ球比(NLR)は、このES-SCLCコホートでは有意な予後価値を示さなかった。
科学分野:
- 腫瘍学; 免疫栄養学; バイオマーカー
背景:
- グラスゴー予後スコア(GPS)、栄養予後指数(PNI)、および好中球リンパ球比(NLR)は、様々な癌において確立された予後指標である。広範期小細胞肺癌(ES-SCLC)におけるそれらの予後的重要性は議論の余地がある。免疫栄養状態は、癌患者の転帰にとって重要である。
研究 の 目的:
- ES-SCLC患者におけるGPS、PNI、およびNLRの予後的価値を評価すること。これらのマーカーがPFSおよびOSを予測できるかどうかを判断すること。ES-SCLCの予後を予測するための信頼できる免疫栄養マーカーを特定すること。
主な方法:
- 一次治療としてプラチナ製剤併用化学療法を受けた102人のES-SCLC患者の後ろ向き解析。治療開始前のGPS、PNI、およびNLRの評価。PFSおよびOS評価のためのカプランマイヤー解析およびコックス比例ハザードモデル。
主要な成果:
- より高いGPS(0/1)およびPNIは、PFSおよびOSの延長と有意に関連していた。NLR群ではPFSまたはOSに有意差は認められなかった。多変量解析により、GPSおよびPNIがPFSおよびOSの独立した予測因子であることが確認された。
結論:
- GPSおよびPNIは、ES-SCLC患者のPFSおよびOSの有意な予後指標である。GPSは、プラチナ製剤併用化学療法で治療されたES-SCLC患者の転帰を予測するためのシンプルで信頼性の高いマーカーである。NLRは、このES-SCLC集団において有意な予後因子ではない。

Certain organic substances change color in dilute solution when the hydronium ion concentration reaches a particular value. For example, phenolphthalein is a colorless substance in any aqueous solution with a hydronium ion concentration greater than 5.0 × 10−9 M (pH < 8.3). In more basic solutions where the hydronium ion concentration is less than 5.0 × 10−9 M (pH > 8.3), it is red or pink. Substances such as phenolphthalein, which can be used to determine the pH of a solution, are...

The Roles of Bacteria and Fungi in Plant Nutrition
47.1K
Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.

Parentral Nutrition: Centeral and Peripheral Parental Nutrition
813
Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...

Organisms exhibit remarkable metabolic diversity, categorized based on how they acquire energy and carbon. These strategies enable survival in various ecological niches and are essential for maintaining energy flow and nutrient cycling within ecosystems.Energy and Carbon SourcesOrganisms are classified as phototrophs or chemotrophs based on energy acquisition. Phototrophs use light as their energy source, while chemotrophs rely on oxidizing chemical compounds. Further differentiation arises...

The air in the lungs is measured in volumes and capacities. Lung volume measures reflect the amount of air taken in, released, or left over after a lung function, like a single inhalation. Lung capacity measures are sums of two or more lung volume measures.

Transcription Factors
82.3K
Tissue-specific transcription factors contribute to diverse cellular functions in mammals. For example, the gene for beta globin, a major component of hemoglobin, is present in all cells of the body. However, it is only expressed in red blood cells because the transcription factors that can bind to the promoter sequences of the beta globin gene are only expressed in these cells. Tissue-specific transcription factors also ensure that mutations in these factors may impair only the function of...
