Dual targeting of the epidermal growth factor receptor using combination of nimotuzumab and erlotinib in advanced non-small-cell lung cancer with leptomeningeal metastases: A report of three cases

Abstract

Leptomeningeal metastases (LM) occur in 3–5% of patients with advanced non-small-cell lung cancer (NSCLC) and are associated with a dismal prognosis. We report three cases of NSCLC with LM who were treated with the combination of nimotuzumab and erlotinib. Magnetic Resonance Imaging (MRI) evaluation during follow-up showed significant improvement in cancer symptoms and decreased tumor size in all three patients. Grade 3 and 4 toxicities were rarely seen. Based on apparent efficacy of the regimen and fewer side effects, we suggest that nimotuzumab in combination with erlotinib may be a promising option for the treatment of NSCLC with LM.
