概括
立体体辐射疗法显著改善了医疗不可操作的早期非小细胞肺癌患者的瘤控制和存活率. 这种治疗为这个高危人群提供了高的局部控制率和可控的毒性.
科学领域:
- 在瘤学瘤学.
- 辐射瘤学 辐射瘤学
- 肺部医学 肺部医学
背景情况:
- 在医疗上无法手术的患者中,早期非小细胞肺癌 (NSCLC) 具有较低的原发性瘤控制率 (30% - 40%),高死亡率 (3年生存率,20% - 35%).
- 这凸显了在这个具有挑战性的患者群体中,对有效治疗策略的关键未满足需求.
研究的目的:
- 评估对患有早期,医学上不可手术的NSCLC的患者的立体体射线疗法 (SBRT) 的疗效和毒性.
- 评估SBRT对初级瘤控制,生存率和与治疗相关的不良事件的影响.
主要方法:
- 一项2期多中心研究招募了18岁以上的患者,其活检证明了外围T1-T2N0M0NSCLC (直径小于5厘米),不适合进行手术.
- 患者接受了SBRT,每小部分为18 Gy,为3个小部分 (共54 Gy) 超过1.5-2周.
- 主要终点是2年的原发性瘤控制;次要终点包括无病生存率,毒性和整体生存率.
主要成果:
- 分析了55名可评估患者 (44名T1,11名T2),随访时间中位数为34.4个月.
- 三年初级瘤控制率为97.6%. 三年后的地方区域控制为87.2%.
- 三年总生存率为55.8%,平均总生存时间为48.1个月. 在16.3%的患者中,发生了3/4级不良事件.

Acute Kidney Injury IV: Diagnostic Studies and Prevention
249
Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...

Disorders of Erythrocytes
2.0K
Disorders of erythrocytes, or red blood cells (RBCs), include a range of conditions affecting their number, shape, or function.
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.

Blood Transfusion and Agglutination
14.0K
Blood transfusion is a therapeutic measure to restore the blood volume after extensive blood loss due to an accident or a medical procedure. Blood transfusion involves drawing a certain amount of blood from a suitable donor and infusing it into the recipient.
History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...

Blood Typing
2.3K
Understanding an individual's blood group is a critical component of transfusion medicine. It ensures compatibility in blood transfusions, organ transplants, and even during pregnancy. Determining these blood groups involves the ABO and Rh blood typing systems, utilizing specific antigens and corresponding anti-sera to identify an individual's blood type.
Antigens are protein molecules that reside on the surface of red blood cells (RBCs). The ABO and Rh blood typing systems target...
