Immunotherapy with the programmed death receptor-1 (PD-1) antibody nivolumab has changed the field of metastatic non-small cell lung cancer (NSCLC) treatment. Nivolumab shows better outcome compared to standard second line chemotherapy, but reliable prognostic markers are lacking. High neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) are markers of host inflammation and associated with worse overall survival (OS) in several tumor types, but have not been analysed extensively in lung cancer in the era of immunotherapy. ⋯ Elevated pre-treatment NLR and PLR are associated with shorter OS and PFS and with lower response rates in patients with metastatic NSCLC treated with nivolumab independently of other prognostic factors.

Anaplastic lymphoma kinase rearrangement (ALK+) occurs in approximately 2-7% of patients with non-small cell lung cancer (NSCLC), contributing to a considerable number of patients with ALK+ NSCLC worldwide. Ceritinib is a next generation ALK inhibitor (ALKi), approved by the European Medicines Agency in 2015. In the first-in-human, phase I study, ceritinib demonstrated rapid and durable responses in ALK patients previously treated with a different ALKi and in those who were ALKi-naive. ⋯ Unfortunately, at some point, all patients experience progressive disease, with the central nervous system being a common site of metastases. Recommendations are made for continuing treatment beyond disease progression as long as a clinical benefit to patients is observed. Here, we review management of ceritinib treatment and adverse events and make recommendations on optimal management of patients.

ALK and ROS1 gene rearrangements are distinct molecular subsets of non-small-cell lung cancer (NSCLC), and they are strong predictive biomarkers of response to ALK/ROS1 inhibitors, such as crizotinib. Thus, it is clinically important to develop an effective screening strategy to detect patients who will benefit from such treatment. In this study, we aimed to validate analytical performance of Vysis ALK/ROS1 Dual Break Apart Probe Kit (RUO) in NSCLC. ⋯ Vysis ALK/ROS1 Dual Break Apart Probe Kit (RUO) can detect ALK and ROS1 rearrangement simultaneously in NSCLC.

This study was performed to clarify whether preoperative serum albumin level is related to the prognosis of non-small cell lung cancer patients undergoing surgical resection, and the relationships between serum albumin level and clinicopathological characteristics of lung cancer patients with emphysema or pulmonary fibrosis. ⋯ Preoperative serum albumin level was an important prognostic factor for overall survival and recurrence-free survival in patients with resected non-small cell lung cancer. Divided into normal lung, emphysema, and pulmonary fibrosis groups, serum albumin level showed no influence only in patients in the emphysema group.

The importance of smoking cessation interventions in lung cancer screening participants has been highlighted. This study aimed to describe the smoking habits of individuals who were ineligible for lung cancer screening and to investigate whether this encounter may represent an opportunity to reduce tobacco use. ⋯ A significant proportion of individuals applying to, but not qualifying for a lung cancer screening program are active smokers with significant nicotine dependence. Very few are currently participating in active smoking cessation programs but almost all are interested in quitting and in receiving help with quit attempts. Future studies need to investigate the most effective approaches for smoking cessation in this substantial group of older, long-term smokers, capitalizing on their motivation to receive cessation assistance.
