概括
与皮肤黑色素瘤 (CM) 患者相比,在手术后接受辅助抗PD-1治疗的甲状腺黑色素瘤 (AM) 患者的复发风险更高,生存结果更差. 需要进一步的研究来改善高风险状黑色素瘤的治疗方法.
科学领域:
- 在瘤学瘤学.
- 皮肤病学 皮肤病学
- 免疫治疗是一种免疫疗法.
背景情况:
- 免疫检查点抑制剂 (ICI) 在不可切除的状黑色素瘤 (AM) 中显示出有限的疗效.
- 在AM切除后的辅助抗PD-1疗法的有效性尚未确定.
- 将AM和皮肤黑色素瘤 (CM) 之间的辅助抗PD-1结局进行比较至关重要.
研究的目的:
- 为了研究和比较状黑色素瘤与皮肤黑色素瘤的临床结果,在完全切除后接受辅助抗PD-1治疗的患者.
- 在两组患者中分析无复发生存率 (RFS),无远程转移生存率 (DMFS) 和整体生存率 (OS).
主要方法:
- 从荷兰黑色素瘤治疗注册表 (2018-2022) 中对1958名患者 (86 AM,1872 CM) 的回顾性分析.
- 纳入标准:接受辅助抗PD-1后完全切除的III-IV期AM和CM患者.
- 统计分析包括RFS的多变量考克斯回归,并对混因素进行调整.
主要成果:
- 在基线时,状黑色素瘤患者有更多的KIT突变,更高的疾病阶段和较差的表现状态.
- 与CM (37.4个月) 相比,AM的RFS中位数显著较短 (14.8个月) (p=0.002).
- 与CM相比,辅助抗PD-1疗法与AM复发的风险更高 (aHR1.53; p=0.019),DMFS恶化 (p=0.050) 和较低的OS (p=0.027) 相关.
结论:
- 与皮肤黑色素瘤患者相比,接受辅助抗PD-1治疗的甲状腺黑色素瘤患者的临床结果较差.
- 目前的辅助抗PD-1策略可能对状黑色素瘤不那么有效.
- 需要进一步的研究来评估辅助治疗的疗效,并探索高风险状黑色素瘤的替代策略.

Tumor Immunotherapy
510
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.

Skin Cancer
4.0K
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.
