There is a lack of large, prospective, randomized studies comparing thoracoscopic and open lobectomy in terms of long-term survival in the setting of NSCLC. Additionally, large case series evaluating the issue are limited. Until now, whether thoracoscopic lobectomy entails a long-term survival benefit compared with open lobectomy not been determined. ⋯ This propensity-matched study suggests that open and thoracoscopic lobectomy are associated with similar long-term survival in the setting of lung cancer. Thoracoscopic lobectomy is an acceptable surgical treatment of lung cancer.

Development of resistance to epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors is a clinical issue in patients with epidermal growth factor receptor gene (EGFR)-mutated non-small cell lung cancer (NSCLC). The aim of this study was to investigate the potential of combining gefitinib and pemetrexed in preventing the acquisition of resistance to EGFR tyrosine kinase inhibitors in NSCLC cell lines harboring EGFR exon 19 deletion. ⋯ The combination of gefitinib and pemetrexed is effective in preventing gefitinib resistance; the application of intermittent treatments requires that gefitinib not be administered before pemetrexed.

The efficacy of pemetrexed-based chemotherapy in patients with advanced lung adenocarcinoma with novel ROS proto-oncogene 1, receptor tyrosine kinase gene (ROS1) oncogenic rearrangement is unclear. This study aimed to compare the efficacy of pemetrexed-based chemotherapy in patients with advanced ROS1-fusion lung adenocarcinoma with its efficacy in those having different driver mutations. ⋯ ROS1 fusion positivity is probably a favorable factor of pemetrexed-based therapy for patients with lung adenocarcinoma.

Comparative Study
CT Features of Epidermal Growth Factor Receptor-Mutated Adenocarcinoma of the Lung: Comparison with Nonmutated Adenocarcinoma.
The purpose of this study was to analyze the high-resolution computed tomography (HRCT) features of lung carcinoma on the basis of epidermal growth factor receptor gene (EGFR) mutation status. ⋯ EGFR-mutated adenocarcinoma showed significantly higher frequencies of multiple bilateral lung metastases, convergence of surrounding structures, surrounding ground glass opacity, and notch at HRCT compared with the non-EGFR-mutated type. Conversely, EGFR-mutated adenocarcinoma showed cavity and pleural effusions less frequently than the nonmutated type did.

Multicenter Study
Patients' Knowledge, Beliefs, and Distress Associated with Detection and Evaluation of Incidental Pulmonary Nodules for Cancer: Results from a Multicenter Survey.
Pulmonary nodules are detected in more than 1 million Americans each year. Prior qualitative work suggests that the detection of incidental pulmonary nodules can be burdensome for patients, but whether these findings generalize to a broader sample of patients is unknown. We categorized patients' knowledge, beliefs, and distress associated with detection and evaluation of a pulmonary nodule, as well as their impressions of clinician communication. ⋯ A quarter of patients with incidental pulmonary nodules experienced clinically significant distress. Knowledge about cancer risk and evaluation was poor. Clinician communication may help bridge knowledge gaps and alleviate distress in some patients.
