Hypoxic lung cancer-derived exosome decreases anticancer activity of NK cell by targeting CD226

In conclusion, our study delineate a new mechanism used by lung cancer cells to inhibit NK cell’s anti-cancer activity through exosome delivery, and inspire further research into the clinical application of miR-150 inhibition for immunotherapy.

Authors: Li S, Zhang S, Liu J, Yang C, Zhang L, Cheng Y Abstract Background: This meta-analysis evaluated the efficacy of PD-L1/PD-1 immunotherapy compared with chemotherapy in IIIB or IV or recurrent squamous non-small cell lung cancer (NSCLC) patients. Methods: We performed a literature search on the PubMed, EMBASE, Web of Science, and Cochrane databases, in addition to the abstracts from major conference proceedings of the European Society for Medical Oncology (ESMO), the American Society of Clinical Oncology (ASCO), and the World Conference on Lung Cancer (WCLC) from 2004 to May 2019. Randomized controlled ...

AbstractSmall-cell lung cancer has defied our scientific community for decades. Chemotherapy has been the mainstay treatment for small-cell lung cancer (SCLC) and unlike its counterpart, non-small cell lung cancer, no significant therapeutic breakthroughs have been made since the 1970s. Among the reasons for this slow-paced therapeutic development, one that stands out is the distinctive and almost universal loss of function of the tumour suppressor genesTP53 andRB1 in this disease, for which pharmacological activation has yet to be achieved, despite having been highly sought after. Although no molecularly targeted approach...

Nature Reviews Clinical Oncology, Published online: 06 January 2020; doi:10.1038/s41571-019-0317-yThe CHECKMATE-227 trial of nivolumab and ipilimumab presents a potential new frontline chemotherapy-sparing treatment option for patients with PD-L1-positive non-small-cell lung cancer and perhaps, in the future, also for those with PD-L1-negative disease. Indeed, the true predictive value of PD-L1 as well as tumour mutational burden remains to be determined, as neither biomarker segregates clearly with responsiveness.

Treatment of stage IV Non Small Cell Lung Cancer (NSCLC) is rapidly evolving. Systemic chemotherapy, targeted therapy or immunotherapy represent the standard of care, depending on both disease biology and patient ’s characteristics. Results in terms of progression free survival (PFS) and overall survival (OS) range between 3-13 months and 5-25 months, respectively. [1–12]

Conclusions: Sebaceous carcinoma currently has few effective adjuvant treatment options. The expression of PD-1, PD-L1, and PD-L2 on infiltrating immune cells and PD-L2 on tumor cells restrains T-cells from full activation and proliferation, therefore limiting the antitumor effect of T-cells, tipping the balance toward unopposed tumor progression. Consequently, PD-1 or PD-L1 inhibitors may have a role in sebaceous carcinoma treatment. Given the prevalence of PD-L2 expression in sebaceous carcinoma and the lack of PD-L2 blockade therapy available, PD-1 blockade may provide benefit over PD-L1 inhibitors. PD-1 blockade in c...

Nivolumab is now a reference treatment for patients with advanced non-small cell lung cancer (NSCLC) after failure of prior platinum-based chemotherapy. Little data are available on treatment approaches following discontinuation of nivolumab and on the interest of a second course of immunotherapy after nivolumab discontinuation. The aims of this study were to describe treatment pathways following nivolumab discontinuation and to describe survival following retreatment with immunotherapy.

Conclusions: Our meta-analysis showed the superiority of combination therapy over monotherapy with chemotherapeutic agents in terms of tumor response, and long-term survival, but with an increased the 3 - 5 grade toxicity. And immune-checkpoint inhibitors alone showed similar tumor response, toxicity and long-term outcomes compared to platinum-based chemotherapy in selected patients.

Authors: Reck M, Shankar G, Lee A, Coleman S, McCleland M, Papadimitrakopoulou VA, Socinski MA, Sandler A Abstract Introduction: Cancer immunotherapy has revolutionized the treatment of patients with advanced or metastatic non-small cell lung cancer (NSCLC). However, specific patient groups (e.g. patients with activating epidermal growth factor receptor [EGFR] mutations) do not appear to derive benefit from immune checkpoint inhibitor (ICI) monotherapy. Combining ICIs, such as atezolizumab, with chemotherapy and/or targeted therapies may help to address this unmet need.Areas covered: Atezolizumab is an anti-program...

BackgroundTo compare survival outcomes of patients with advanced or metastatic non ‐small cell lung cancer (NSCLC) who received immunotherapy as first‐, second‐ or beyond line, versus matched patients receiving standard chemotherapy with special characterization of hyperprogressors.MethodsA retrospective cohort study of 296 patients with unresectable/metastatic NSCLC treated with either, first ‐, second‐, third‐ or fourth‐line of immunotherapy was conducted. A matched comparison with a historical cohort of first‐line chemotherapy and a random forest tree analysis to characterize hyperprogressors was conduct...
