Pembrolizumab for choroidal metastases from non-small cell lung cancer: a case report and literature review

Abstract

We described a 65-year-old male with choroidal metastases (CM) from non-small cell lung cancer (NSCLC). Pembrolizumab (Keytruda) combined with pemetrexed and capecitabine achieved excellent outcomes. After two cycles of pembrolizumab and chemotherapy, blurred vision and left eye pain were significantly relieved. Imaging and ophthalmologic examinations demonstrated complete resolution of the CM, as well as reduction of pulmonary shadow. CM from NSCLC shows complete and durable response to pembrolizumab and chemotherapy. We suggesting that immunotherapy combined with chemotherapy is a promising treatment for CM from NSCLC.
