https://www.selleckchem.com/products/bgb-283-bgb283.html Immune infiltration in neuroblastoma (NBL) has been associated with clinical outcome. However, the diversity of distinct immune subpopulations that comprise immune infiltrates in NBL has not been examined. To this end, the present study investigated the immunological landscape of NBL tumors and its clinical significance. CIBERSORTx, an established RNA deconvolution algorithm, was used to impute immune cell proportions from 153 primary NBL tumors. Associations between immune proportions and overall/event-free survival were analyzed by Kaplan-Meier curves and evaluated using log-rank test. Of the 22 subpopulations imputed, M2 macrophages were the most abundant subtype in NBL tumors. Furthermore, monocytes, CD4+ naïve T cells, and CD4+ activated memory T cells were significantly associated with survival. Altogether, the findings suggest differences amongst certain immune cell subsets comprising NBL tumor infiltration and these differences may be important determinants of prognosis. From 2011 to 2016, 13 randomized clinical trials with active controls were submitted to U.S. Food and Drug Administration (FDA) for the treatment of advanced melanoma. While regular approval is generally granted due to a substantial improvement in overall survival (OS), or a large, clinically meaningful improvement in progression-free survival (PFS), accelerated approval can be granted based on incremental change in a surrogate end point reasonably likely to predict clinical benefit, such as objective response (ORR) of large magnitude and long duration. However, the relationship between objective response rate and progression free survival or objective response rate and overall survival in advanced melanoma has not been established. We conducted analyses to assess the correlation of objective response rate with progression free survival as well as overall survival by examining all advanced melanoma trials submitted to the FDA between 2
