The Immunomodulatory Effects of Dexamethasone on Neoadjuvant Chemotherapy for Triple-Negative Breast Cancer.

Introduction: The immunomodulatory impact of corticosteroids and concurrent chemotherapy is poorly understood within triple-negative breast cancer (TNBC). On a biochemical level, steroids have been linked to the signaling of chemotherapy-resistant pathways. However, on a clinical level, steroids play an essential role in chemotherapy tolerance through the prevention of chemotherapy-induced nausea and vomiting (CINV) and hypersensitivity reactions.

Mean platelet volume, thrombocytosis, and survival in non-small cell lung cancer patients treated with first-line pembrolizumab alone or with chemotherapy.

Introduction: Patients treated with immune checkpoint inhibitors (ICIs) may not response to treatment and are at risk for immune-related adverse events (irAEs). Platelet function has been linked to both oncogenesis and immune evasion. We studied the association between the change in mean platelet volume (MPV), platelet count, survival, and the risk of developing irAEs in patients with metastatic non-small cell lung cancer (NSCLC) who have received first-line ICI.

Immune checkpoint inhibitor-induced hepatitis injury: risk factors, outcomes, and impact on survival.

Purpose: Immune checkpoint inhibitors (ICIs) are associated with a unique set of immune-related adverse events (irAEs). Few studies have evaluated the risk factors and outcomes of patients who develop ICI-induced hepatitis (ICIH).

Methods: We utilized an institutional database of patients with advanced cancers treated with ICI to identify patients with ICIH.

Combining immune checkpoint inhibition plus tyrosine kinase inhibition as first and subsequent treatments for metastatic renal cell carcinoma.

Background: Immune checkpoint inhibitor/tyrosine kinase inhibitor (ICI/TKI) combinations are a new standard of care for the initial treatment of metastatic renal cell carcinoma (mRCC). Their efficacy and toxicity beyond the first-line setting remain poorly defined.

Methods: We retrospectively reviewed charts for 85 adults with mRCC of any histology receiving combination of ICI/TKI in any line of treatment at two academic centers as of 05/01/2020.

Salvage nivolumab and ipilimumab after prior anti-PD-1/PD-L1 therapy in metastatic renal cell carcinoma: A meta-analysis.

Background: Salvage nivolumab and ipilimumab after prior anti-PD-1/PD-L1 therapy is frequently used off-label for clear cell metastatic renal cell carcinoma (mRCC). However, limited data are available to guide such therapy. We performed a meta-analysis to characterize further the safety and efficacy of salvage nivolumab and ipilimumab.

Assessment of Leptomeningeal Carcinomatosis Diagnosis, Management and Outcomes in Patients with Solid Tumors Over a Decade of Experience.

Objective: Leptomeningeal carcinomatosis (LMC), a common complication of advanced malignancies, is associated with high morbidity and mortality, yet diagnosis and treatment decisions remain challenging. This study describes the diagnostic and treatment modalities for LMC and identifies factors associated with overall survival (OS).

Materials And Methods: We performed a single-institution retrospective study (registration #: OSU2016C0053) of 153 patients diagnosed with LMC treated at The Ohio State University, Comprehensive Cancer Center, (OSUCCC)-James between January 1, 2010 and December 31, 2015.

Immune checkpoint inhibitor-related thrombocytopenia: incidence, risk factors and effect on survival.

Introduction: Immune checkpoint inhibitors (ICI) are associated with unique immune-related adverse events (irAEs). Immune-related thrombocytopenia (irTCP) is an understudied and poorly understood toxicity; little data are available regarding either risk of irTCP or the effect of irTCP on clinical outcomes of patients treated with ICI.

Methods: We conducted a retrospective review of sequential cancer patients treated with ICI between 2011 and 2017 at our institution.

Bone Metastases, Skeletal-Related Events, and Survival in Patients With Metastatic Non-Small Cell Lung Cancer Treated With Immune Checkpoint Inhibitors.

Background: Bone metastases and skeletal-related events (SREs) are a frequent cause of morbidity in patients with metastatic non-small cell lung cancer (mNSCLC). Data are limited on bone metastases and SREs in patients with mNSCLC treated using immune checkpoint inhibitors (ICIs), and on the efficacy of bone-modifying agents (BMAs) in this setting. Here we report the incidence, impact on survival, risk factors for bone metastases and SREs, and impact of BMAs in patients with mNSCLC treated with ICIs in a multi-institutional cohort.

Brief report: inhaled corticosteroid use and the risk of checkpoint inhibitor pneumonitis in patients with advanced cancer.

Background: Checkpoint inhibitor pneumonitis (CIP) is an immune-related adverse event that may complicate treatment with immune checkpoint inhibitors (ICI) and can cause significant morbidity. We sought to identify predictors for the development of CIP, and whether the use of inhaled corticosteroids (ICS) at time of ICI may be protective.

Methods: Patients with advanced cancer treated with ICI from 2011 and 2018 were included in this study.

Inferring the role of the microbiome on survival in patients treated with immune checkpoint inhibitors: causal modeling, timing, and classes of concomitant medications.

Background: The microbiome has been shown to affect the response to Immune Checkpoint Inhibitors (ICIs) in a small number of cancers and in preclinical models. Here, we sought to broadly survey cancers to identify those in which the microbiome may play a prognostic role using retrospective analyses of patients with advanced cancer treated with ICIs.

Methods: We conducted a retrospective analysis of 690 patients who received ICI therapy for advanced cancer.

Effects of pre-freeze Nigella sativa oil supplementation on cryosurvival of ovine spermatozoa.

The study was designed with three experiments to evaluate the effects of pre-freeze supplementation of Nigella sativa oil (NSO) and thymoquinone (TQ) on total motility, progressive motility, biokinetic characteristics, acrosomal integrity and DNA integrity of cryopreserved ovine spermatozoa. Semen samples collected from three proven fertile Merino rams were diluted with a Tris-based cryomedia containing different levels of NSO (Experiment I: 0, 10, 100 and 1,000 g/ml), TQ (Experiment II: 0, 1, 10 and 20 g/ml) and their optimum levels (Experiment III: 100 g/ml of NSO, 10 g/ml of TQ and 1 mM of α-tocopherol and cryopreserved as pellet (200µL) and subsequently evaluated at different post-thaw incubation periods (0, 2 and 4 hr). The results revealed that the percentage of total motility, progressive motility and biokinetic characteristics such as average path velocity, curvilinear velocity and straight-line velocity were higher (p < 0.
