{Abstract}: Currently, women with metastatic or recurrent cervical cancer still have very limited treatment options. Despite the rapid advancements in targeted therapies, no targeted therapy was approved for cervical cancer, except for bevacizumab. In the present study, we reported a 52-year-old heavily pre-treated EGFR amplified patient with metastatic cervical squamous cancer who benefited from afatinib with a progression-free survival (PFS) of 5.5 months. The patient was administered with a first-line treatment of chemotherapy and bevacizumab with a PFS of 4.3 months. Subsequently the patient was treated with a second-line regimen of angiogenesis inhibitor apatinib plus chemotherapy and a third-line treatment of pembrolizumab. Genomic profiling revealed significant EGFR amplification in both primary (copy number [CN] =15.9) and metastatic lesions (CN =18). Afatinib monotherapy was then administered as the fourth-line regimen. She achieved partial response (PR) with a PFS of 5.5 months. At disease progression, the CN of EGFR was elevated to 39.9 accompanied by the emergence of PIK3CA amplification (CN =4.2). The patient was treated with everolimus and afatinib and achieved stable disease (SD) after 3 months. To the best of our knowledge, this is the first clinical evidence of an EGFR-amplified metastatic cervical cancer patient benefiting from afatinib as a single agent.
