A 68-year-old woman was diagnosed with stage IVA pulmonary LELC. After multiple-line chemotherapy, her disease progressed. Since the PD-L1 expression rate of the patient was 90%, nivolumab was administered. However, the therapeutic effect of nivolumab was not ideal; the disease continued to progress, and a new cervical lymph node metastasis appeared. FGFR3 gene amplification was detected in lymph node metastasis. Based on this gene abnormality, we added anlotinib to the treatment. After two cycles of anlotinib and nivolumab, the metastatic focus of the patient was significantly reduced. The patient continued to receive this combined treatment and achieved remission for more than 15 months.
