Stereotactic ablative radiotherapy (SABR) has been recognized as a standard alternative treatment to surgery for inoperable early stage non-small cell lung cancer (NSCLC). Guaranteed local control rates over 90% makes oncologists wonder whether SABR is qualified enough to challenge surgery in operable patients. The role of SABR for centrally located lesions would be another question because of the increased risk of severe toxic effect. Plenty of studies suggest that optimization of dose regimen and appropriate case selection would be helpful...

BACKGROUND: The aim of this study was to investigate the diagnostic value of the intravoxel incoherent motion (IVIM) for distinguishing non-metastatic from metastatic mediastinal lymph nodes in lung cancer. METHODS: IVIM-diffusion weighted imaging (DWI) exams were performed preoperatively on 66 patients with lung cancer from October 2015 to June 2016 in Beijing Chao-Yang Hospital, Capital Medical University. Fifty patients underwent enhanced chest computed tomography (CT) in our hospital, while the other 16 patients already had enhanced chest CT images when they were admitted...

Programmed cell Death Ligand 1 (PD-L1) is part of an immune checkpoint system that is essential for preventing autoimmunity and cancer. Recent approaches in immunotherapy targeting immune checkpoints have shown great promise in a variety of cancers, including metastatic melanoma. The use of targeted molecular imaging would help identify patients who will best respond to anti-PD-L1 treatment while potentially providing key information to limit immune-related adverse effects (irAEs). Recently, we developed an antibody based PD-L1-targeted imaging agent to identify PD-L1 positive tumors in vivo...

Cytotoxic T lymphocyte antigen-4 (CTLA-4) is expressed during cluster of differentiation (CD)4+ T-cell activation and terminates immune responses by interrupting CD28-enhanced activation. In addition, CTLA-4 is known to be constitutively expressed in regulatory T-cells (Tregs) and to contribute to immune suppression by enhancing the suppressive function of Tregs. However, the molecular mechanisms underlying CTLA-4-mediated Treg suppression remains incompletely understood. Furthermore, it is uncertain whether the in vivo immune suppressive functions of CTLA-4 are mediated only by a reduction in the level of conventional T-cell activity, or enhancement of Treg function...

BACKGROUND: Advances in cancer immunotherapy have generated encouraging results in multiple malignancies refractory to standard chemotherapies. As the use of immune checkpoint inhibitors (ICI) proliferates, the incidence of autoimmune side effects associated with these agents, termed immune related adverse events (irAE), is expected to increase. The frequency of significant irAE in ICI treated patients is about 10-20% and early recognition is critical to prevent serious morbidity and even mortality...

In 2017, immunotherapy is the standard of care for patients with non-small cell lung cancer (NSCLC) either in the first or second line depending on programmed death ligand-1 (PD-L1) and mutation status. For first-line therapy, pembrolizumab is currently the standard of care for patients whose tumors express PD-L1 >50%. All patients with NSCLC should undergo PD-L1 testing before initiating treatment on pembrolizumab. For patients not eligible in the first line, immunotherapy is the standard of care for most in the second line...

Year after year, a growing number of cases of non-small cell lung cancer (NSCLC), mostly caused by smoking, have been noted. Most patients die because of the late detection of cancer and tumor resistance to treatment with cytostatics. Treatment of patients with advanced NSCLC is impeded by the low sensitivity of the tumor to cytostatic agents and the co-existence of many diseases, which substrate is, like lung cancer, cigarette smoking. Along with the development of molecular biology, targeted therapy has started to be used, affecting specific signaling pathways involved in the processes of oncogenesis...

In this study, the safety and clinical efficacy of cryosurgery combined with allogenic NK cell immunotherapy for the treatment of advanced non-small cell lung cancer (NSCLC) were evaluated. From July 2016 to March 2017, we enrolled 60 patients who met the enrollment criteria and divided them into two groups: (1) the simple cryoablation group (n = 30) and (2) the cryoablation combined with allogenic NK cell group (n = 30). The changes in immune function, quality of life, and clinical response were evaluated...

Anaplastic lymphoma kinase (ALK) inhibitors have been successfully developed for non-small cell lung carcinoma (NSCLC) displaying chromosomal rearrangements of the ALK gene, but unfortunately resistance invariably occurs. Blockade of the PD-1-PD-L1/2 inhibitory pathway constitutes a breakthrough for the treatment of NSCLC. Some predictive biomarkers of clinical response to this therapy are starting to emerge, such as PD-L1 expression by tumor/stromal cells and infiltration by CD8(+) T cells expressing PD-1...

Monoclonal antibodies that target either PD-1 or PD-L1 have recently been approved for treatment of advanced non-small cell lung cancer. These antibodies are immune checkpoint inhibitors which have been shown to exacerbate Myasthenia Gravis (MG) and other autoimmune diseases. While effective in preventing tumor cells from evading immune attack, immune checkpoint inhibitors such as nivolumab, an antibody directed against the programmed cell death protein-1 (PD-1) receptor located on T-cells, may also cause immune dysregulation and could cause or potentiate pre-existing autoimmune conditions...

Cancer survival rates are generally increasing in the United States. These trends have been partially attributed to improvement in therapeutic strategies. Cancer immunotherapy is an example of one of the newer strategies used to fight cancer, which primes or activates the immune system to produce antitumor effects. The first half of this review paper concisely describes the cell mechanisms that control antitumor immunity and the major immunotherapeutic strategies developed to target these mechanisms. The second half of the review discusses in greater depth immune checkpoint inhibitors that have recently demonstrated tremendous promise for the treatment of diverse solid tumor types, including melanoma, non-small cell lung cancer, and others...

Immunotherapy is a promising field that harnesses the power of the immune system as a therapeutic agent for cancer treatment. Beneficial outcomes shown in patients with non-small cell lung cancer (NSCLC) and malignant pleural mesothelioma (MPM) with relatively higher tumor-infiltrating T cells, combined with impressive responses obtained in a cohort of patients with NSCLC following checkpoint blockade therapy, lays a strong foundation to promote effector immune responses in these patients. One such approach being investigated is administration of tumor antigen-targeted T cells with transduction of a chimeric antigen receptor (CAR)...

Nivolumab, a PD-1 immune-checkpoint inhibitor antibody, has been approved in the second line for metastatic squamous non-small cell lung cancer (sqNSCLC)(1). However, only a minority of patients respond to anti-PD-1 immunotherapy, and mechanisms of de novo and adaptive resistance to nivolumab are unclear. There are limited treatment options to rescue the immunotherapy refractory status. We herein describe a patient who was nivolumab refractory and subsequently developed global response after a course of palliative thoracic radiotherapy (RT)...

BACKGROUND: Lung cancer risk prediction models have the potential to make programs more affordable; however, the economic evidence is limited. METHODS: Participants in the National Lung Cancer Screening Trial (NLST) were retrospectively identified with the PLCOm2009 risk-prediction tool. The high-risk subgroup was assessed for lung cancer incidences and demographic character compared with the low-risk subgroup and the Pan-Canadian Early Detection of Lung Cancer Study (PanCan)-an observational study, that was high-risk selected in Canada...

High hydrostatic pressure (HHP) can be used to generate dendritic cell (DC)-based active immunotherapy for prostate, lung and ovarian cancer. We showed here that HHP treatment of selected human cancer cell lines leads to a degradation of tumor antigens which depends on the magnitude of HHP applied and on the cancer cell line origin. Whereas prostate or ovarian cell lines displayed little protein antigen degradation with HHP treatment up to 300MPa after 2h, tumor antigens are hardly detected in lung cancer cell line after treatment with HHP 250MPa at the same time...

Lung cancer is the leading cause of cancer-related deaths worldwide with over 1 million deaths each year. The overall prognosis of lung cancer patients remains unsatisfactory, with a 5-year overall survival rate of less than 15%. Although most lung cancers are a result of smoking, approximately 25% of lung cancer cases worldwide are not attributable to tobacco use. Notably, more than half of the lung cancer cases in women occur in non-smokers. Among non-small-cell lung cancer (NSCLC) cases, cigarette-smokers have a greater association with squamous cell carcinoma than adenocarcinoma, which is more common in non-smokers...

In recent years, immunotherapy has come to the forefront as a major development in cancer treatment. Evasion of the immune system by tumor cells has been identified as one of the hallmarks of cancer and multiple therapies have been developed to counter this process. Programmed cell death 1 ligand 1 (PD-L1), a ligand to programmed cell death protein 1 (PD-1), is expressed by many cancer cells and the binding of PD-L1 to PD-1 results in the suppression of T-cell-mediated immune response against cancer cells. Atezolizumab is a monoclonal antibody that binds to PD-L1 and blocks its interaction with PD-1, thereby enhancing T-cell activity against tumor cells...
