概括

在胰腺癌 (PC) 的粒子放射治疗 (PRT) 后,胃肠道出血 (GIB) 发生在32%的患者中. 虽然在所有病例中都实现了静血,但并发化疗可能会降低GIB风险.

科学领域:

在瘤学瘤学.
辐射疗法辐射疗法
胃肠病学胃肠病学

背景情况:

粒子辐射疗法 (PRT) 为无法切除的胰腺癌 (PC) 提供了一种新的治疗方法.
在PC的PRT后,关于胃肠道出血 (GIB) 的现实数据有限,这是一个显著的不良事件.

研究的目的:

评估PC的PRT后GIB的发病率和结果.
在这个患者队列中确定与GIB相关的风险因素.

主要方法:

进行了一项单一中心的回顾性研究.
分析了34名为PC接受PRT的患者的数据.
评估了GIB的频率,结果和潜在的风险因素.

主要成果:

32%的患者在PRT后经历了急性GIB,中位数发病时间为13.2个月.
大多数情况下,输血是通过内镜或通过栓塞进行管理的;所有人都实现了血液静止.
同时进行化疗与GIB风险降低有关 (P=0.05).

结论:

胰腺癌的PRT后胃肠道出血可能比以前认为的更常见.
对于晚期胰腺癌的PRT需要对GIB进行仔细监测.
同时进行化疗可能会减轻GIB风险.

Esophageal Varices-II: Clinical Features and Management

Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.
In the initial assessment, a thorough review of the patient's medical history is vital to identify risk factors such as liver disease, alcohol...

Radiological Investigation III: Pulmonary Angiogram and PET Scan

Radiological Investigation III: Pulmonary Angiogram and PET Scan

Radiological investigations are paramount in the diagnosis and management of various pulmonary diseases. Two essential investigations are the Pulmonary Angiogram and the Positron Emission Tomography (PET) Scan.
Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
