Randomized Controlled Trial Multicenter Study
A randomized controlled trial comparing indwelling pleural catheters with talc pleurodesis (NVALT-14).
Symptomatic malignant pleural effusion (MPE) occurs frequently in patients with metastatic cancer. The associated prognosis is poor and the success rate of talc pleurodesis (TP) is low. Indwelling pleural catheters (IPCs) are commonly inserted when TP has been unsuccessful. ⋯ IPC was not superior in the primary endpoint, improvement of the modified Borg scale (MBS). However, IPC patients had lower hospital stay, fewer admissions and fewer re-interventions. The IPC is an effective treatment modality in patients with symptomatic malignant pleural effusion.

Randomized Controlled Trial Clinical Trial
Preliminary evaluation of a telephone-based smoking cessation intervention in the lung cancer screening setting: A randomized clinical trial.
Incorporating effective smoking cessation interventions into lung cancer screening (LCS) programs will be essential to realizing the full benefit of screening. We conducted a pilot randomized trial to determine the feasibility and efficacy of a telephone-counseling (TC) smoking cessation intervention vs. usual care (UC) in the LCS setting. In collaboration with 3 geographically diverse LCS programs, we enrolled current smokers (61.5% participation rate) who were: registered to undergo LCS, 50-77 years old, and had a 20+ pack-year smoking history. ⋯ This study provides preliminary evidence that telephone-based cessation counseling is feasible and efficacious in the LCS setting. As millions of current smokers are now eligible for lung cancer screening, this setting represents an important opportunity to exert a large public health impact on cessation among smokers who are at very high risk for multiple tobacco-related diseases. If this evidence-based, brief, and scalable intervention is replicated, TC could help to improve the overall cost-effectiveness of LCS.

Case Reports
EGFR exon 18 delE709_T710insD mutated stage IV lung adenocarcinoma with response to afatinib.
Epidermal Growth Factor Receptor (EGFR) targetable mutations have changed the landscape for treatment of advanced stage non-small cell lung cancer in recent years. Three generations of tyrosine kinase inhibitors are now available to target cancers harboring these mutations. The most common EGFR mutations occur in Exons 19 and 21. ⋯ We discuss the reported cases of delE709_T710insD mutated non-small cell lung cancer variably treated with geftinib, erlotinib or afatinib. This particular exon 18 mutation seems to preferentially respond to afatinib as reported in two cases including the current case, and in an in vitro experimental model. These reports have implications in guiding decisions for treatment of patients harboring rare EGFR mutations.

Dysregulation of the downstream PI3K/AKT/mTOR signaling pathway is a proposed mechanism of resistance to epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs). We investigated safety and antitumor activity of afatinib plus sirolimus as a potential combination to reverse acquired resistance to EGFR-TKIs in a phase IB trial in patients with EGFR mutation-positive non-small-cell lung cancer (EGFR mut NSCLC) and/or disease progression following prior erlotinib/gefitinib. ⋯ NCT00993499.
