Multicenter Study
Histology significantly affects recurrence and survival following SBRT for early stage non-small cell lung cancer.
Contrary to prevailing notions of uniform efficacy regarding stereotactic body radiation therapy (SBRT) for early-stage non-small cell lung cancer (NSCLC), a recent report has indicated increased risk of local failure for squamous cell carcinoma (SCC). As those data have not been corroborated by other studies, we performed a multi-institutional analysis to evaluate the influence of histology on post-SBRT outcomes. ⋯ This multi-institutional analysis corroborates that SCC histology is independently predictive for local, regional, and distant recurrence and worse overall survival. Future data are needed to determine if treatment paradigms should differ by histology for early stage NSCLC.

In lung cancer and other malignancies, the so-called "liquid biopsy" is quickly moving into clinical practice. Its full potential has not yet been fully identified, but the "liquid biopsy" is no longer a promise but has become a reality that allows for better treatment selection and monitoring of lung cancer. This emerging field has significant potential to make up for the limitations of the traditional tissue-derived biomaterials. ⋯ Recently, a growing number of studies has focused on exosomal cargo and their use in lung cancer genesis and progression. In addition, their utility as lung cancer diagnostic, prognostic and predictive biomarkers have also been studied. The current review primarily summaries lung cancer-related exosomal biomarkers that have recently been identified and discusses their potential in clinical practice.

Small-cell lung cancer (SCLC) has been viewed as a smoking-related disease, with only 2% to 5% patients being never-smokers. This study aimed to investigate the clinical characteristics of never-smoking and its association with treatment outcomes in Chinese SCLC patients in real world. ⋯ The current study indicated that never-smokers are increasingly prevalent in Chinese patients with SCLC. Never-smokers with SCLC had significantly longer PFS and OS compared with smokers, and smoking was an independent poor prognostic factor for PFS in patients with SCLC.

In patients with refractory or recurrent non-small-cell lung cancer (NSCLC) after first line chemotherapy, phase III trials showed superiority of nivolumab, an IgG4 programmed death-1 immune-checkpoint-inhibitor antibody, over docetaxel. We evaluated case mix, effectiveness and safety of nivolumab upon implementation in general practice. ⋯ Upon implementation of nivolumab therapy in general hospitals, the case mix was characterized by a more heavily pretreated population with a substantial fraction of patients with ECOG score 2. The median overall survival is slightly inferior to what was published in the randomized phase III trials. An ECOG score 2 and the presence of liver metastasis correlated strongly with a worse survival. We report a high prevalence of serious adverse events.
