Efficacy and safety analysis of the German expanded access program of osimertinib in patients with advanced, T790M-positive non-small cell lung cancer.

Purpose: Osimertinib, a third-generation irreversible mutant-selective inhibitor of EGFR kinase activity was clinically evaluated in the AURA trials, where it showed high clinical efficacy and a favorable toxicity profile in patients with acquired exon 20-EGFR pT790M mutation. We provide the clinical data of the German expanded access program that further characterizes the efficacy and safety of osimertinib in a heterogeneous patient population outside clinical trials.

Methods: We performed a retrospective data analysis on patients who were included into the German osimertinib EAP.

Cutaneous involvement as a rare first sign of systemic mantle cell lymphoma: A case report and review of the literature.

Mantle cell lymphoma (MCL) is a unique type of B-cell non-Hodgkin's lymphoma, which very rarely exhibits skin involvement. We herein describe the case of a 55-year-old woman, who initially presented with a nodular mass of the right infraorbital region. On histological analysis of the subcutaneous tissue, a diffuse neoplastic cell infiltration was identified, composed of medium-sized lymphoid cells with irregular nuclei, which was diagnosed as MCL.
