[Safety analysis of eight patients treated with erlotinib after severe gefitinib-induced liver injury].

Gefitinib and erlotinib are commercially available epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) that are widely used for the treatment of non-small-cell lung cancer (NSCLC). Acute severe liver injury, although rare, has been observed in patients receiving these EGFR-TKIs. Some studies have reported that erlotinib treatment does not cause severe liver toxicity in patients with NSCLC who previously presented with severe liver injury during the course of gefitinib treatment.
