Treatment Options for Patients with Non-Small Cell Lung Cancer and Liver Metastases

Lung cancer represents the most common cause of cancer-related death. Patients with non-small cell lung cancer (NSCLC) and liver metastases have worse prognosis, with an overall survival (OS) from three to six months. The majority of them have a poor response to chemotherapy, and the data are controversial regarding the response to immunotherapy. This could be because the liver is considered to be an immune-tolerant organ, which is characterized by T-cell anergy and immunosuppressive signals. This review evaluates current treatment options for patients with NSCLC and liver metastases. Combination therapies might be a better treatment option for this subgroup of patients. The addition of radiotherapy to immunotherapy could also be an option in selected patients. The resection of single liver metastasis should also be considered.
