免疫检查点抑制剂 (ICI) 在一项试点研究中显著降低了行动性角质瘤 (AKs) 和角质细胞癌 (KCs). 这表明ICI可能提供一种新的策略,用于预防高风险个体的新皮肤癌症.
科学领域:
- 皮肤病学 皮肤病学
- 在瘤学瘤学.
- 免疫学 免疫学 免疫学
背景情况:
- 针对单个角质细胞癌 (KC) 的疗法不能防止阳光损伤皮肤中新的KC的发展.
- 现场癌症,其特点是行为性角质 (AKs) 和KCs,在皮肤癌管理中构成了持续的挑战.
研究的目的:
- 调查免疫检查点抑制剂 (ICI) 与现场癌症化变化之间的关联.
- 在12个月内评估ICI对AK和KC数量的影响.
主要方法:
- 一项前性队列研究,涉及23名接受ICI治疗的免疫能力强的成年人 (PD-1/PD-L1抑制剂).
- 在基线和3,6个月和12个月,AKs被计数和拍摄.
- 通过从ICI启动前后12个月的组织病理学报告来评估KC数量.
主要成果:
- 平均AKs显著下降,从基线时的47.2降至12个月后的14.3 (P < .001).
- 总的KC数量从42减少到17,皮肤状细胞癌从16减少到5.
- 年轻的患者和有太阳烧史的患者更有可能实现显著的AK减少.
结论:
- ICI显示了AKs的显著减少,这表明它有可能成为高风险个体的免疫预防策略.
- 需要进一步的研究来探索ICI用于管理现场癌症,考虑到它们的疗效,毒性和成本.

When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
