Safety, Efficacy, and Biomarker Analysis of Crizotinib in MET-Mutated Non-Small Cell Lung Cancer-Results from the Drug Rediscovery Protocol.

Purpose: To provide patients with MET-mutated advanced non-small cell lung cancer (METmut aNSCLC) access to crizotinib, further substantiate evidence of its efficacy and safety in this setting, and find potential biomarkers for nonresponse.

Patients And Methods: In the Drug Rediscovery Protocol (NCT0295234), patients with an actionable molecular profile are treated with off-label registered drugs. Both treated and untreated patients with aNSCLC harboring MET exon 14 skipping or other MET mutations received crizotinib 250 mg BID until disease progression or intolerable toxicity.

Birt-Hogg-Dubé syndrome in apparent primary spontaneous pneumothorax patients; results and recommendations for clinical practice.

Background: Birt-Hogg-Dubé syndrome (BHD) is an inherited disease caused by pathogenic variants in the FLCN gene. One of the characteristics is the increased risk for spontaneous pneumothorax, likely due to the presence of pulmonary cysts mainly distributed under the carina. Due to variable expression and lack of awareness, BHD is likely to be underdiagnosed.

Renal imaging in 199 Dutch patients with Birt-Hogg-Dubé syndrome: Screening compliance and outcome.

Birt-Hogg-Dubé syndrome is associated with an increased risk for renal cell carcinoma. Surveillance is recommended, but the optimal imaging method and screening interval remain to be defined. The main aim of our study was to evaluate the outcomes of RCC surveillance to get insight in the safety of annual US in these patients.
