概括
治疗前预后营养指数 (PNI) 可以预测接受免疫检查点抑制剂 (ICI) 的癌症患者的免疫相关不良事件 (irAEs). 较高的PNI (≥44.2) 与增加的irAE发病率和更长的无进展生存时间相关.
科学领域:
- 在瘤学瘤学.
- 免疫学 免疫学 免疫学
- 临床生物标志物 临床生物标志物
背景情况:
- 免疫相关不良事件 (irAEs) 是免疫检查点抑制剂 (ICI) 治疗的常见副作用,影响各种器官和患者的结果.
- 对irAEs的预测生物标志物对于优化癌症治疗策略和患者管理至关重要.
- 预后营养指数 (PNI) 是营养状况的标志物,尚未被广泛研究作为irAEs的预测指标.
研究的目的:
- 调查治疗前预后营养指数 (PNI) 与接受ICI治疗的癌症患者中IRE发生的相关性.
- 建立一个PNI切割值,预测irAE发展.
- 评估PNI对该患者队伍无进展生存期 (PFS) 的影响.
主要方法:
- 对接受固定剂量ICI单疗的111名癌症患者进行了回顾性调查.
- 在有和没有irAEs的患者中,PNI进行了比较.
- 确定了PNI截止值,并根据此截止值分析了irAE发生率和PFS.
主要成果:
- 与没有发生irrAEs的患者相比,患有irrAEs的患者的PNI明显更高.
- 在PNI和irAEs之间发现了显著的关联,即使经过调整以考虑混因素 (OR,1.12;95% CI,1.03-1.21)).
- PNI≥44.2与较高的irrAEs发病率 (75.0%对35.2%,p=0.0001) 和显著更长的PFS (p=0.025) 相关.
结论:
- 治疗前的PNI可以作为治疗ICI治疗的晚期复发性固体瘤患者的irAEs的预测生物标志物.
- 一个PNI≥44.2表明一个更高的风险的irAEs,需要谨慎的患者管理,以减轻潜在的严重不良事件.
- 虽然ICI可以有效,但PNI可能预测的IRE风险需要在治疗计划中考虑.

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding
148
Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.

Enteral Nutrition I: Orogastric and Nasogastric Feeding
287
Enteral nutrition delivers nutrients directly to the stomach or small intestine through a tube. This method is appropriate for patients who cannot eat but still have a functioning digestive system. It is also beneficial for individuals with swallowing difficulties, anorexia, malabsorption, or those who have undergone gastrointestinal (GI) surgery.
Orogastric (OG) and nasogastric (NG) feeding are two standard methods used for enteral nutrition. Enteral nutrition is often preferred over...

Psychoneuroimmunology: Diabetes and Cancer

Chronic stress has been linked to both the onset and progression of serious health conditions, including Type 2 diabetes and cancer. Type 2 diabetes, a widespread chronic illness, is closely associated with obesity and insulin resistance, both of which often worsen under stress. Studies indicate that men experiencing high levels of chronic stress face a 45% higher risk of developing diabetes compared to those with minimal stress. Stress triggers physiological responses that elevate blood...
