概括
许多乳腺癌免疫疗法试验未能报告结果,尤其是单中心研究. 很大一部分II期试验没有导致成功的III期试验,限制了临床影响.
科学领域:
- 在瘤学瘤学.
- 临床试验 临床试验
- 免疫治疗是一种免疫疗法.
背景情况:
- 临床试验对于开发新疗法至关重要,但报告失败可能会阻碍进展和患者的信任.
- 评估乳腺癌免疫疗法试验的结果对于了解它们对现实世界的影响至关重要.
研究的目的:
- 从2004年到2023年,分析乳腺癌免疫疗法试验的情况.
- 确定未能报告结果的试验比例,并确定相关的试验特征.
- 评估报告的试验的成功率和从II期研究转移到III期研究.
主要方法:
- 在clinicaltrials.gov.gov注册的乳腺癌免疫疗法试验的横截面研究.
- 从clinicaltrials.gov获取数据,并通过谷歌学者,pubmed和larvol clini的搜索进行补充.
- 使用费舍尔精确测试进行统计分析,以确定试验特征和报告结果之间的关联.
主要成果:
- 在331个启动的试验中,120个试验的完成日期为2022年11月,其中30个试验 (25%) 没有报告结果.
- 与多中心研究 (15.0%) 相比,单中心研究不报告 (35.2%) 的可能性要高得多.
- 在报告的90项试验中,52.2%为阳性,47.8%为阴性. 值得注意的是,报告的随机试验中有89.5%是负面的.
结论:
- 大量的乳腺癌免疫疗法试验产生了适度的临床影响.
- 有相当数量的单中心试验没有报告结果,这表明需要改进报告实践.
- 许多II期研究未能成功转化为III期试验,这表明药物开发管道存在差距.

Tumor Immunotherapy
504
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.

Cancer Vaccines
350
Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...
