Patients with epidermal growth factor receptor (EGFR) gene-mutated non-small cell lung cancer (NSCLC) obtain substantial clinical benefit from EGFR tyrosine-kinase inhibitors (TKIs), but will ultimately develop TKI-resistance resulting in median progression-free survival of 9-15 months during first-line TKI-therapy. However, type and timing of TKI-resistance cannot be predicted and several mechanisms may simultaneously/subsequently occur during TKI-treatment. In this respect, we present a 49 year-old Caucasian male ex-smoker with metastatic pulmonary adenocarcinoma (ADC) that concomitantly harbored an EGFR exon 19-mutation (p. ⋯ The patient rapidly deteriorated and deceased. Thus, this advanced EGFR-mutated NSCLC displayed very rapid onset and heterogeneous genetic and phenotypic mechanisms of TKI-resistance occurring at different times and locations of metastatic disease: concomitant FGFR3-mutation before and during TKI-treatment as potential intrinsic mechanism for the rapid progression; transformation to SCLC at first progression during TKI-therapy; acquired T790M EGFR-mutation at second progression. Our case also underlines that, when achievable, rebiopsies of progressive sites during TKI-treatment are important for identifying heterogeneous histopathological and molecular resistance mechanisms and better defining possible treatment modifications.

Randomized Controlled Trial Multicenter Study
Relationship between nodule count and lung cancer probability in baseline CT lung cancer screening: The NELSON study.
To explore the relationship between nodule count and lung cancer probability in baseline low-dose CT lung cancer screening. ⋯ In baseline lung cancer CT screening, half of participants with lung nodules have more than one nodule. Lung cancer probability does not significantly change with the number of nodules. Baseline nodule count will not help to differentiate between benign and malignant nodules. Each nodule found in lung cancer screening should be assessed separately independent of the presence of other nodules.

Review
Patient-reported outcome measures (PROMs) in the management of lung cancer: A systematic review.
Lung cancer is often associated with a poor quality of life, as reflected by patient-reported outcome measures (PROMs). The aim of this paper is to describe and compare the PROMs that are available. In this manuscript, we review the impact of PROMs on the management of lung cancer. ⋯ The EORTC QLQ-C30 and its lung cancer-specific module QLQ-LC13 are the most frequently used instruments in lung cancer patients. PROMs have the potential to improve the quality of care with a proper implementation in the routine practice. PROMS are needed to value and understand the experience of the patient.

In a phase Ib trial, afatinib plus cetuximab demonstrated promising clinical activity (objective response rate [ORR]: 29%; median progression-free survival [PFS]: 4.7 months) in patients with epidermal growth factor receptor (EGFR) mutation-positive non-small-cell lung cancer (NSCLC) with acquired resistance to erlotinib or gefitinib. Here, a separate cohort exploring afatinib plus cetuximab after progression on afatinib is reported. ⋯ NCT01090011.
