Immuno-oncology therapies represent a new treatment opportunity for patients affected by metastatic melanoma. The purpose of this study was to estimate the costs of immune-related adverse events (irAEs) associated with the new anti-PD1 immuno-oncology therapies, with the anti-CTLA-4 immuno-oncology therapy and with the combined therapy (CTLA4 + anti-PD1) in patients affected by metastatic melanoma. ⋯ This study may represent a useful tool to understand the economic burden associated with the management of irAEs associated with patients affected by metastatic melanoma.

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.
