黑色素瘤

起源于黑色素细胞;发生于皮肤和黏膜;进展快,死亡率高;人种差异明显

黑色素瘤的“ABCDE”

Asymmetry 不对称性 Border 边缘 Color 颜色 Diameter 直径 Evolving 进展

 “丑小鸭理论”

在同一个体中观察越来越像彼此,而MM经常偏离本痣图案。这种临床实现指向不仅评估病变有关的形态,但也比较来周围病变,寻找在类似显现摩尔的背景的离群值的重要性。例如,该离群病变可以比周围的摩尔(图1A)放大和更暗,或者相反地,小型和红中的多个大的暗摩尔(图1B)的背景。最后,如果患者具有很少或没有其他摩尔(图1C),任何改变病变应被视为可疑异常值。

不同组织来源的肿瘤恶性进程不同

基因改变影响信号通路

早期诊断与早期治疗

完整切除;辅以放疗、免疫治疗;靶向治疗

最后,那么肿瘤消退是好现象吗?

        常见于水平生长期肿瘤;肿瘤部分消退与较薄黑色素瘤早期转移相关;

研究背景: 促分裂素原活化蛋白激酶 (MAPK) 信号转导通路是细胞内最重要的信号通路之一, 该通路通过RAS、RAF、有丝分裂原活化蛋白激酶 (MEK) 及胞外信号调节激酶 (ERK) 的特异性级联磷酸化将信号由细胞外传入细胞核内。BRAF是RAF三个亚型之一,是MAPK通路重要的转导因子。在催化底物方面, BRAF以MEK1/2为底物,是MEK最主要的活化激酶。 BRAF在3个亚型
