概括

新辅助性葡萄糖皮质激素 (GCs) 通过提高切除能力并使更少的侵入性手术成为可能,改善了高级B型胸腺瘤的手术结果. 这一战略还显示了中期疾病控制的改善,这表明了管理这些具有挑战性的瘤的有希望的方法.

科学领域:

在瘤学瘤学.
胸部外科手术胸部外科手术
药理疗法药理疗法药理疗法

背景情况:

局部发达的B型胸腺瘤带来了重大的手术切除挑战.
传统的新辅助疗法在改善手术可行性方面存在局限性.
葡萄糖皮质类药物 (GCs) 被探索为一种新辅助剂降级策略.

研究的目的:

评估新辅助性葡萄糖皮质激素 (GCs) 在改善晚期B型胸腺瘤手术结果方面的疗效.
评估GCs对切除能力,手术参数和患者存活率的影响.
为了比较接收GCs之后进行手术的患者与立即手术之间的结果.

主要方法:

对患有Masaoka-Koga阶段III-IV B型胸腺瘤的患者 (2017-2024) 的倾向性得分匹配分析.
干预组接受了手术前2-4周的口服普雷迪尼松酸盐 (0.6毫克/千克/天) (GC+手术,n=36).
对照组接受了立即手术 (手术,n=36). 结果包括手术参数,并发症和生存率.

主要成果:

新辅助性GCs实现了64.8%的客观响应率 (13.2%完全,51.6%部分).
在GC+手术组显示显著减少了手术时间 (182.8比426.0分钟) 和血液损失 (165比1285毫升).
R0切除率更高 (97.2%与86.1%相比),增强了VATS利用率 (55.6%与13.9%) 和改善了5年无进展生存率 (83.4%与72.4%相比).

结论:

新辅助性葡萄糖皮质类药物增强了高级B型胸腺瘤的切除能力.
这种方法可能有助于减少侵入性外科手术 (VATS).
GCs显示出改善中期疾病控制的潜力,在晚期胸腺瘤患者.

Drugs for Treatment of Crohn's Disease in IBD Using Glucocorticoids

Glucocorticoids, a class of anti-inflammatory drugs, are pivotal in treating moderate to severe Crohn's disease by inducing remission. They exhibit their anti-inflammatory action by inhibiting the production of inflammatory cytokines such as tumor necrosis factor (TNF)-α, interleukin (IL)-1, and chemokines like IL-8. In addition, they reduce the expression of inflammatory cell adhesion molecules and inhibit gene transcription of nitric oxide synthase, phospholipase A2, cyclooxygenase-2...

Inflammatory Bowel Disease V: Surgical Management

Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
Here are some common surgical interventions for IBD:
