概括
体重不足的体重指数 (BMI) 与晚期黑色素瘤患者的无进展生存率恶化有关. 较高的骨肌密度和较低的内脏脂肪改善了整体生存率,独立于其他因素.
科学领域:
- 在瘤学瘤学.
- 放射学 放射学是一门学科.
- 身体组成分析 身体成分分析
背景情况:
- 身体组成和黑色素瘤免疫疗法的有效性之间的关系尚不清楚.
- 关于体重指数 (BMI) 和治疗结果的现有研究显示了相互矛盾的结果.
研究的目的:
- 调查BMI和计算机断层扫描 (CT) 衍生的身体组成指标与先进黑色素瘤患者治疗一线免疫治疗的存活率的关联.
- 分析大量黑色素瘤患者队列,以澄清身体成分在预测治疗反应中的作用.
主要方法:
- 对来自11个中心的1471名晚期黑色素瘤患者进行了回顾性分析,这些患者接受了抗PD1±抗CTLA4治疗.
- 提取五个CT衍生体质成分指标:皮下脂肪组织指数,内脏脂肪组织指数,骨肌肉指数,密度和尺度.
- 这些指标与无进展生存率 (PFS),总生存率 (OS) 和黑色素瘤特异性生存率 (MSS) 的相关性,使用单变量和多变量Cox比例危险分析.
主要成果:
- 体重不足的患者表现出明显更差的PFS (HR=1.86).
- 较高的骨肌密度 (HR=0.88) 和尺度 (HR=0.61) 与改善的OS相关.
- 内脂肪组织指数增加与更差的OS相关 (HR=1.12).

Skin Cancer
3.0K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

Tumor Immunotherapy
463
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.
