概括
与PD-1抑制剂和TP疗法的新辅助化疗免疫疗法显著改善了局部晚期下癌 (LAHPC) 的病理反应和喉保存率. 这种方法表明了良好的无进展生存率,特别是在第四阶段的患者中.
科学领域:
- 在瘤学瘤学.
- 免疫治疗是一种免疫疗法.
- 头部和部癌症研究研究
背景情况:
- 局部晚期下腺癌 (LAHPC) 存在重大治疗挑战.
- 新辅助疗法旨在改善手术结果和生存率.
研究的目的:
- 在LAHPC中评估新辅助化学免疫治疗 (PD-1抑制剂+TP疗法) 的疗效.
- 评估病理反应,喉保护手术 (LPS) 率和无进展生存率 (PFS).
主要方法:
- 对46名接受新辅助PD-1抑制剂和TP (阿尔伯结合的帕克利塔塞尔+思普拉丁) 的LAHPC患者进行了回顾性研究.
- 主要终点:主要病理反应 (MPR). 二级终点:整体反应率 (ORR),LPS率,PFS.
- 分析了MPR和ORR之间的相关性.
主要成果:
- 高ORR (71.9%) 和LPS率 (80.4%,在第四阶段为76.5%).
- 观察到显著的MPR (52.2%) 和病理完整反应 (pCR) (32.6%).
- 优秀的一年和两年PFS率 (97.1%和93.8%). 实现MPR与更好的预后相关 (P=0.008).
结论:
- 与PD-1抑制剂和TP疗法的新辅助化疗免疫疗法对LAHPC有效.
- 改善了MPR和LPS率,特别是在IV期患者中.
- 该疗法显示出有利的安全性概况,具有可管理的不良事件.

491
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

02:49Cancer Therapies
7.6K
Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

1.4K
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
