Follow-up after first-Line nivOlumab plus ipilimumab in patients with diffuse pleuRal mesotheliomA: a real-world Dutch cohort study-FLORA.

Background: Diffuse pleural mesothelioma (dPM) is an aggressive malignancy, primarily treated with palliative systemic therapy. Since 2022, nivolumab-ipilimumab (nivo/ipi) has replaced chemotherapy as the standard first-line treatment for dPM in the Netherlands. Chemotherapy remains a rational second-line treatment.

The prediction of treatment outcome in NSCLC patients harboring an EGFR exon 20 mutation using molecular modeling.

Introduction: The structural effect of uncommon heterogenous in-frame deletion and/or insertion mutations within exon 20 (EGFRex20+) in relation to therapy response is poorly understood. This study aims to elucidate the structural alterations caused by EGFRex20+ mutations and correlate these changes with patient responses.

Material And Method: We selected EGFRex20+ mutations from advanced NSCLC patients in the Position20 and AFACET studies for computational analysis.

A comprehensive overview of the heterogeneity of EGFR exon 20 variants in NSCLC and (pre)clinical activity to currently available treatments.

Activating EGFR mutations are commonly observed in non-small cell lung cancer (NSCLC). About 4-10 % of all activating epidermal growth factor receptor (EGFR) mutations are heterogenous in-frame deletion and/or insertion mutations clustering within exon 20 (EGFRex20+). NSCLC patients with EGFRex20+ mutations are treated as a single disease entity, irrespective of the type and location of the mutation.

High dose osimertinib in patients with advanced stage EGFR exon 20 mutation-positive NSCLC: Results from the phase 2 multicenter POSITION20 trial.

Introduction: Patients with life-threatening advanced non-small cell lung cancer (NSCLC) who harbor an exon 20 deletion and/or insertion mutation (EGFRex20 + ) have limited effective treatment options. The high dose 3rd generation tyrosine kinase inhibitor (TKI) osimertinib shows promising in vitro activity in EGFRex20 + NSCLC tumors.

Methods: The POSITION20 is a single arm phase II, multicenter study investigating 160 mg osimertinib in patients with EGFRex20+, T790M negative NSCLC.

A brief report on combination chemotherapy and anti-programmed death (ligand) 1 treatment in small-cell lung cancer: Did we choose the optimal chemotherapy backbone?

Extensive-stage small-cell lung cancer (ES-SCLC) is an aggressive cancer that remains very hard to treat. The life expectancy of a patient diagnosed with this disease has not changed over the past three decades. Recently, three large clinical studies showed a survival benefit by adding an anti-programmed death (ligand) 1 (PD-(L)1 antibody to the current chemotherapy regimen.
