Systemic and local immunosuppression in patients with high-grade meningiomas

ConclusionsPatients with meningiomas exhibit signs of peripheral immunosuppression, including increased PD-L1 on myeloid cells and elevated MDSC abundance proportional to tumor grade. Additionally, the tumors express substantial PD-L1 proportional to tumor grade. These results suggest a role for immune checkpoint inhibitors targeting the PD-L1/PD-1 pathway in combination with standard therapies for the treatment of high-grade meningiomas.

Publication date: Available online 20 July 2019Source: Seminars in Cancer BiologyAuthor(s): Nancy A. Espinoza-Sánchez, Martin GötteAbstractOver the past few decades, understanding how tumor cells evade the immune system and their communication with their tumor microenvironment, has been the subject of intense investigation, with the aim of developing new cancer immunotherapies. The current therapies against cancer such as monoclonal antibodies against checkpoint inhibitors, adoptive T-cell transfer, cytokines, vaccines, and oncolytic viruses have managed to improve the clinical outcome of the patients. However,...

Authors: Olbryt M Abstract Melanoma is the most aggressive skin cancer with an increasing number of cases worldwide and curable mostly in its early stage. The improvement in patients' survival in advanced melanoma has been achieved only recently, due to development of new biological drugs for targeted therapies and immunotherapy. Further progress in the treatment of melanoma is clearly dependent on the better understanding of its complex biology. This review describes the most important molecular mechanisms and genetic events underlying skin melanoma development and progression, depicts the way of action of newly d...

Authors: Cabanillas ME, Ryder M, Jimenez C Abstract The treatment of advanced thyroid cancer has undergone rapid evolution in the past decade, with multiple kinase inhibitor drug approvals for each subtype of thyroid cancer and a number of other commercially available drugs that have been studied for this indication. While most of the FDA approved drugs are anti-angiogenic multikinase inhibitors-vandetanib, cabozantinib, sorafenib, lenvatinib-there are two FDA indications that are mutation specific-dabrafenib/trametinib for BRAF mutated anaplastic thyroid cancer and larotrectinib for NTRK fusion thyroid cancer. Fur...

Authors: Gilmore E, McCabe N, Kennedy RD, Parkes EE Abstract Historically the development of anticancer treatments has been focused on their effect on tumor cells alone. However, newer treatments have shifted attention to targets on immune cells, resulting in dramatic responses. The effect of DNA repair deficiency on the microenvironment remains an area of key interest. Moreover, established therapies such as DNA damaging treatments such as chemotherapy and PARP inhibitors further modify the tumor microenvironment. Here we describe DNA repair pathways in breast cancer and activation of innate immune pathways in DNA...

Kim, Hong Shan, Depei Wu, Wen JiangImmune cells rely on a functional vascular network to enter tissues. In solid tumors, blood vessels are abnormal and dysfunctional and, thus, immune effector cell infiltration is impaired. Although normalizing the tumor vasculature has been shown to improve the efficacy of cancer immunotherapies, recent studies suggest that enhanced immune stimulation also, in turn, improves tumor vascular normalization. Thus, this new paradigm of immune syst...
