A 76-year-old woman with cT1bN2M1b stage IVA spindle cell carcinoma of the right lower lobe of the lung, no driver gene mutation, and programmed death ligand 1 < 1%, was started on ipilimumab+nivolumab+carboplatin+paclitaxel. After two courses, the patient initiated maintenance therapy with ipilimumab+nivolumab. New multiple brain metastases were observed during treatment but resolved with continued treatment. We report a unique case of spindle cell carcinoma treated with ipilimumab+nivolumab+carboplatin+paclitaxel that resulted in long-term response and resolution of new brain metastasis.
Keywords: brain metastasis; ipilimumab; lung cancer; nivolumab; spindle cell carcinoma.
