Metastatic small cell neuroendocrine carcinoma of the cervix treated with the PD-1 inhibitor, nivolumab: a case report

摘要

BackgroundNivolumab is an immune checkpoint inhibitor specific for the programmed death 1 (PD-1) receptor that has led to clinical responses in many cancer types. Identifying biomarkers predictive of response to PD-1 blockade is an area of active investigation. Case presentationWe present a patient with recurrent, metastatic, PD-L1-negative small cell neuroendocrine carcinoma of the cervix (SCNEC) who experienced a complete response to nivolumab. Though nivolumab was discontinued over 4?months ago due to treatment-related adverse events, she continues to have no evidence of disease. ConclusionsImmune checkpoint inhibitors may be active in neuroendocrine cervical cancer, with potential for dramatic responses in a modest subset of patients.
