J Am Acad Dermatol:基因突变和家族史会影响黑色素瘤患者的结局

2017-08-31 MedSci MedSci原创

研究人员已经注意到,多发性原发性侵袭性皮肤恶性黑色素瘤(MPM)患者比单一原发性黑色素瘤患者有更差的结局。

背景:研究人员已经注意到,多发性原发性侵袭性皮肤恶性黑色素瘤(MPM)患者比单一原发性黑色素瘤患者有更差的结局。目的:本研究旨在探讨黑色素瘤的家族史和MPM患者的生殖细胞系CDKN2A突变影响后续黑色素瘤的其它癌症的发展的风险,以及它们影响生存结果的风险。方法:研究人员通过瑞典国家卫生和人口登记处数据获得了MPM患者的癌症诊断和死亡的综合数据、他们的亲属,并给患者匹配了对照组。结果:在第二个黑色素瘤被诊断出时,存在生殖细胞系CDKN2A突变的家族性MPM病例的年龄最年轻(年龄中位数为42岁),且在整个MPM队列中,与对照组相比,改组患者未来黑色素瘤>2个的相对风险最高(RR 238.4,95% CI 74.8-759.9)。与对照组相比,CDKN2A突变的MPM患者和他们的直系亲属是唯二的非皮肤癌风险增加的两组(RR 3.6,95% CI 1.9-147.1和RR 3.2,95% CI 1.9-5.6)。此外,与存在家族史和罕见的野生型MPM患者相比,CDKN2A突变的MPM患者的生存更差(分别为:HR 3,95% CI 1.3-8.1;HR 2.63,95% CI 1.3-5.
