概括
新辅助化学放射疗法 (nCRT) 改善了第二阶段食道癌的存活率. 对于第三阶段,局部瘤从nCRT中获益,而转移型可能从新辅助化疗 (nCT) 中获益更多.
科学领域:
- 在瘤学瘤学.
- 手术瘤学手术瘤学
- 胃肠病学 胃肠病学
背景情况:
- 食道癌症的治疗需要定制的新辅助疗法.
- 个性化治疗策略对于优化患者的治疗结果至关重要.
- 了解瘤入侵模式会影响治疗决策.
研究的目的:
- 评估可操作的食道癌症的个性化新辅助疗法.
- 为了比较新辅助化疗或放射治疗 (nCRT),新辅助化疗 (nCT) 和单独手术的有效性.
- 根据瘤阶段和侵袭模式分析治疗结果.
主要方法:
- 从SEER数据库中对95,444名食道癌患者 (2010-2017年) 的回顾性分析.
- 对第二阶段食道癌进行nCRT,nCT和单独手术的比较.
- 在nCRT和nCT的有效性分析中,将III期患者分为"局部侵入性" (I型) 和"区域转移性" (II型) 组.
主要成果:
- 对于第二阶段食道癌,nCRT的整体存活率 (OS) (85.1%) 与nCT (3.0%) 和单独手术 (11.9%) 相比显著更高. 中位 OS:nCRT的54个月.
- 在第三阶段食管癌中,接受nCRT的"局部侵入型"患者的生存状况 (中位数为45个月) 比"区域转移型"患者 (中位数为28个月) 更好.
- 在接受nCT的III期"区域转移型"患者中,中位数的生存期为51个月,这表明相对于"局部侵入型" (中位数为40个月) 有潜在的益处.
结论:
- 新辅助化学放射治疗 (nCRT) 建议用于第二阶段食道癌.
- 患有"局部侵入型"瘤的第三阶段食道癌患者可能从nCRT中显著受益.
- 患有"区域转移型"瘤的第三阶段食道癌患者可能从nCT中获得更大的益处.

Endoscopic Studies I: Bronchoscopy and Thoracoscopy
Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...

Barrett Esophagus-I: Introduction
Barrett's esophagus is a medical condition where the esophageal mucosa is significantly damaged by stomach acid or other digestive fluids, often due to long-term exposure associated with gastroesophageal reflux disease (GERD). In GERD, a weakened or abnormally relaxed lower esophageal sphincter allows stomach acid to flow persistently into the esophagus.
This constant acid exposure transforms the esophagus's pink mucosal lining (stratified squamous epithelium) into a type of lining more similar...

Barrett Esophagus-II: Clinical Manifestations and Management
Individuals with Barrett's esophagus are often asymptomatic, but they may experience symptoms commonly associated with GERD, such as heartburn and acid regurgitation. Additional symptoms can include difficulty swallowing, chest pain, unintentional weight loss, blood in the stool (which may appear black, tarry, or bloody), and episodes of vomiting.
To diagnose Barrett's esophagus, healthcare providers often recommend an endoscopy for those showing symptoms of acid reflux. The procedure entails...

Endoscopic Procedures I: Esophagogastroduodenoscopy
An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:
