Long Term Survivor with Erlotinib in Metastatic Lung Cancer-Squamous Cell Carcinoma Subtype.

Currently, data that supports the clinical benefit of agents targeting the epidermal growth factor receptor (EGFR) in the therapy of squamous cell carcinoma (SCC) histologic version of the lung cancer (LC) is insufficient. In the following report we present the case of a patient treated with erlotinib for SCC NSCLC. At the time of initiation, there were no available guidelines recommendations regarding the EGFR status in for initiation of EGFR tyrosine kinase inhibitors (TKIs) therapy for NSCLC, thus the sample was never tested for the EGFR mutational status. Not widely used in the treatment of SCC, EGFR-TKIs remain a valid therapeutic option in selected groups of patients.
