Merkel cell carcinoma (MCC) is an aggressive cutaneous neuroendocrine malignancy with limited treatment options. Several lines of evidence support the programmed death-1/programmed death-ligand 1 (PD-1/PD-L1) axis as a likely contributor to immune evasion in MCC.
We report a case of a patient with metastatic MCC with a significant and durable response to nivolumab, a humanized IgG4 monoclonal anti-PD-1 antibody.
Immunotherapy with PD-1/PD-L1 inhibitors has become a rational and promising treatment option for MCC in the advanced or metastatic disease. Clinical trials are currently in progress to further evaluate these novel therapeutic agents.
默克尔细胞癌(MCC)是一种侵袭性皮肤神经内分泌恶性肿瘤,治疗选择有限。有几项证据表明,程序性死亡受体 1/程序性死亡配体 1(PD-1/PD-L1)轴可能是 MCC 免疫逃逸的原因之一。
我们报告了一例转移性 MCC 患者,其对 nivolumab(一种人源化 IgG4 单克隆抗 PD-1 抗体)有显著且持久的反应。
PD-1/PD-L1 抑制剂的免疫治疗已成为晚期或转移性 MCC 的一种合理且有前途的治疗选择。目前正在进行临床试验,以进一步评估这些新型治疗药物。
