Osimertinib is the best treatment choice for patients with epidermal growth factor receptor (EGFR)-mutated advanced non-small-cell lung cancer (NSCLC) whose disease progresses on a first- or second-generation EGFR-tyrosine kinase inhibitor due to acquired T790M mutation. On the other hand, there is a lack of therapeutic strategies with proven efficacy at the time of progression on osimertinib. If not administered previously, platinum-based chemotherapy can provide some clinical benefit, while immunotherapy does not seem to work in this setting.

Abstract

Osimertinib is the best treatment choice for patients with epidermal growth factor receptor (EGFR)-mutated advanced non-small-cell lung cancer (NSCLC) whose disease progresses on a first- or second-generation EGFR-tyrosine kinase inhibitor due to acquired T790M mutation. On the other hand, there is a lack of therapeutic strategies with proven efficacy at the time of progression on osimertinib. If not administered previously, platinum-based chemotherapy can provide some clinical benefit, while immunotherapy does not seem to work in this setting. Here, we report on a unique case of response to osimertinib rechallenge after intervening chemotherapy in an EGFR T790M-positive NSCLC patient pretreated with the sequence erlotinib-osimertinib.
