Circulating molecular biomarkers of lung cancer may allow the pre-selection of candidates for computed tomography screening or increase its efficacy. We aimed to identify features of serum mass profile distinguishing individuals with early lung cancer from healthy participants of the lung cancer screening program. ⋯ We developed a serum mass profile-based signature identifying patients with early lung cancer. Although this marker has insufficient value as a stand-alone preselecting tool for LD-CT screening, its potential clinical usefulness in evaluation of indeterminate pulmonary nodules deserves further investigation.

Human epidermal growth factor receptor 2 (HER2, ERBB2) mutations occur in 3% of lung adenocarcinomas. While case reports and series have shown activity of HER2 targeted agents in these patients, little is known about outcomes of chemotherapies. Patients with stage IV HER2-mutant lung cancers at Memorial Sloan Kettering were reviewed. ⋯ The median duration of chemotherapy was 4.3 months (68 treatments, range 0-21 months): 6.2 months for pemetrexed ±platinum/bevacizumab, 4 months for taxane ±platinum/bevacizumab, 2.6 months for gemcitabine, 3.5 months for vinorelbine. The median duration of HER2 tyrosine kinase inhibitors was 2.2 months (28 treatments, range 0.3-16.3 months). As we search for better targeted therapies for patients with HER2-mutant lung cancers, chemotherapy remains an important component of care.

Immunotherapy such as nivolumab is a new promising therapeutic option for advanced stage non small cell lung cancer (NSCLC). Due to the interference with the immune system previously unknown side effects are observed both in clinical studies and experience. ⋯ Up to now there is only limited information regarding potential cardiac side effects. We present a case of symptomatic drug induced myocarditis after nine cycles of nivolumab in a patient with efficient anticancer response.

Programmed death-ligand 1 (PD-L1) is known to be over-expressed in non-small cell lung cancer (NSCLC). However, the impact of chemotherapy on the altered status of PD-L1 expression has not been examined for NSCLC. The present study was intended to examine the impact of neoadjuvant chemotherapy on PD-L1 expression and its prognostic significance in lung squamous cell carcinoma (SCC). ⋯ Neoadjuvant chemotherapy may up-regulate the expression of PD-L1. As compared with the status of PD-L1 expression prior to chemotherapy, the postoperative expression of PD-L1 is a better prognostic factor for overall survival in SCC.

Prior studies have shown an anticancer effect of statins in patients with certain malignancies. However, it is unclear whether statins have a mortality benefit in lung cancer. We compared survival of patients with stage IV non-small cell lung cancer (NSCLC) receiving vs. not receiving statins prior to diagnosis. ⋯ Statin use is associated with improved survival among patients with stage IV NSCLC suggesting a potential anticancer effect. Further research should evaluate plausible biological mechanisms as well as test the effect of statins in prospective clinical trials.
