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 2011 and 2016. In order to examine these relationships, associations betor overall survival or progression free survival in this population appears not appropriate. read more However, due to the nature of heterogeneity, interpretation needs to be cautious.
Based on this analysis, use of objective response rate as a surrogate endpoint for overall survival or progression free survival in this population appears not appropriate. However, due to the nature of heterogeneity, interpretation needs to be cautious.
While transplant recipients are aware of increased malignancy risk, there is little consensus on the preventative measures. The goal of this review is to bring available preventative measures to light and prompt more research to be done with ultimate goal of developing an individualized prevention plan for each patient based on risk factors and available screening tools.

Transplant surgery offers patients with end-stage renal disease a longer life expectancy with help of immunosuppressive therapies. Nonetheless, life-long immunosuppression comes at a cost of post-renal transplant malignancies, which have become the leading cause of morbidity in this patient group.

Post-renal transplant cancers can develop through either de novo, by donor-related transmission, or recurrence of recipient's pre-transplant cancer. While immunosuppressive therapy is considered to be the leading cause, weakened immunosurveillance of neoplastic cells and inadequate immune response against oncogenic viruses also plays an importof choice, it may lead to graft failure. Given some of the presented malignancies have modifiable risk factors and options for screening, clinical outcomes can be improved. Limiting skin exposure, dermatologic screening, and prophylactic retinoids can help lower the incidence rate of skin malignancy. Endoscopic screening for renal transplant patients can help identify gastric adenocarcinoma early and improve survival rates. Some of the post-transplant malignancies have been responsive to anti-viral treatment.Atezolizumab is an immune checkpoint inhibitor that is a key drug in non-small-cell lung cancer treatment. However, it can cause immune-related adverse events, including liver injury. Several patterns of liver injury associated with immune checkpoint inhibitor therapy have been reported; however, not much is known about sclerosing cholangitis. We present here a case of lung adenocarcinoma with atezolizumab-induced secondary sclerosing cholangitis diagnosed using needle biopsy of the liver. A 77-year-old woman with lung adenocarcinoma, cT3N2M0, stage IIIA, was treated with concurrent chemoradiotherapy involving carboplatin and paclitaxel, which markedly reduced the tumor diameter. However, 5 months later, the lesion regrew, and she underwent 39 cycles of pemetrexed monotherapy. As pulmonary metastasis progressed, she was treated with atezolizumab. After 13 cycles of atezolizumab therapy, she complained of nausea. Laboratory tests showed elevated levels of the biliary tract and hepatic enzymes. Nevertheless, abdominal computed tomography and ultrasonography revealed no underlying related cause. Ultrasound-guided needle biopsy of the liver was performed, and histopathological analysis of biopsy samples showed features of sclerosing cholangitis. Further examinations were performed, and a diagnosis of atezolizumab-induced secondary sclerosing cholangitis without strictures and dilatations of the large bile ducts was established. Prednisolone was administered orally, after which the biliary tract and hepatic enzyme levels improved immediately. In patients presenting with a hepatic injury during immune checkpoint inhibitor therapy, clinicians should be aware of the possibility of immune checkpoint inhibitor-induced sclerosing cholangitis, even if the large bile ducts have no strictures and dilatations.On March 11, 2020 the World Health Organization announced that the COVID-19 disease developed into a global pandemic. In the present paper, we aimed at analysing how the implementation of Non-Pharmaceutical Interventions (NPI) as well as climatic, social, and demographic variables affected the initial growth rate of COVID-19. In more detail, we aimed at identifying and assessing all the predictors in a whole picture of the COVID-19 outbreak and the effectiveness of the response of the countries to the pandemic. It can be expected, indeed, that there is a subtle and complex interplay among the various parameters. As such, we estimated the initial growth rate of COVID-19 for countries across the globe, and used a multiple linear regression model to study the association between the initial growth rate and NPI as well as pre-existing country characteristics (climatic, social and demographic variables measured before the current epidemic began). We obtained a mean initial growth rate of 0.120 (SD 0.076), in the range 0.
