Sci Rep:乳头状肾细胞癌亚型MYC免疫组化治疗的不同预后值分析

2017-12-11 AlexYang MedSci原创

乳头状肾细胞癌(pRCCs)的组织形态学亚型分类改善了病人的长期生存的预测。基于之前的研究,有研究人员假设MYC原癌基因会在pRCC不同的亚型中展现出不同的表达模式。为了验证这个假设,研究人员在一个204名pRCC患者的多类型群体中,评估了免疫组化标记MYC、MINA53和Ki67在预测病人长期生存中的附加值。临床结果点为总生存(OS)和癌症特异性生存(CSS)。研究人员还构建了列线图来预测每个病

乳头状肾细胞癌(pRCCs)的组织形态学亚型分类改善了病人的长期生存的预测。基于之前的研究,有研究人员假设MYC原癌基因会在pRCC不同的亚型中展现出不同的表达模式。

为了验证这个假设,研究人员在一个204名pRCC患者的多类型群体中,评估了免疫组化标记MYC、MINA53和Ki67在预测病人长期生存中的附加值。临床结果点为总生存(OS)和癌症特异性生存(CSS)。研究人员还构建了列线图来预测每个病人死亡的风险。MYC染色模式的使用允许了研究人员对pRCC类型1病人进行分层,从而分配到更好的和更差的预后小组中。

研究发现,患有pRCC类型1肿瘤和良好的MYC染色模式的病人没有因肿瘤相关起因导致死亡。并且该预后值在外科手术、肿瘤病理阶段和淋巴结入侵中,不依赖于病人的年龄。另外,研究人员指出,MYC的免疫组化评估和pRCC的组织形态学亚型分析能够对pRCC类型1肿瘤进行分层,并且还考虑到OS和CSS。最后,研究人员指出,pRCC亚型组织形态学的确定结合MYC免疫组化染色模式,能够促使人们对病人个人的死亡风险进行更为准确的评估。
