Objectives: To identify predictive gene-expression signatures for immune-related adverse events (irAEs) in patients with melanoma treated with anti-PD-1 inhibitors, in the adjuvant therapy (AT) and first-line therapy (FLT).

Methods: This retrospective study analyzed baseline whole-blood gene expression profile from 161 patients with resected stage III or unresectable stage III-IV melanoma treated with anti-PD-1 inhibitors. RNA was extracted from baseline peripheral blood samples and profiled using the NanoString nCounter PanCancer IO 360 panel.

Patients with solid tumors and a higher body mass index (BMI) experience improved survival after receiving anti-PD1 antibodies. The predictive role of BMI in Hodgkin Lymphoma (HL), the most sensitive malignancy to PD1-blockade, remains unclear. We analyzed the association between BMI and survival outcomes in patients treated with the anti-PD-1 antibody nivolumab within the CheckMate 205 study.

Background: Immune checkpoint inhibitors (ICIs), such as anti-Cytotoxic T-Lymphocyte Antigen 4(CTLA-4) and anti-Programmed cell death protein 1 (PD-1) agents, have improved the prognosis of patients with metastatic melanoma. However, a proportion of patients develop resistance to these treatments, leading to a poor prognosis. Therefore, identifying potential non invasive and easy to measure biomarkers is crucial for guiding treatment strategies in patients with metastatic melanoma.

Testicular germ cell tumors (TGCTs), the most common malignancies affecting young men, are characterized by high sensitivity to cisplatin-based chemotherapy, which leads to high cure rates even in metastatic disease. However, approximately 30% of patients with metastatic TGCTs relapse after first-line treatment and those who can be defined as platinum-refractory patients face a very dismal prognosis with only limited chemotherapy-based treatment options and an overall survival of few months. Hence, to understand the mechanisms underlying cisplatin resistance is crucial for developing new treatment strategies.

We previously demonstrated that patients with metastatic unresectable stage IIIb-IV melanoma receiving cetirizine (a second-generation H1 antagonist antihistamine) premedication with immunotherapy had better outcomes than those not receiving cetirizine. In this retrospective study, we searched for a gene signature potentially predictive of the response to the addition of cetirizine to checkpoint inhibition (nivolumab or pembrolizumab with or without previous ipilimumab). Transcriptomic analysis showed that inducible T cell costimulator ligand (ICOSLG) expression directly correlated with the disease control rate (DCR) when detected with a loading value > 0.

Immune checkpoint inhibitors (ICIs) improve outcomes in advanced melanoma, but many patients are refractory or experience relapse. The gut microbiota modulates antitumor responses. However, inconsistent baseline predictors point to heterogeneity in responses and inadequacy of cross-sectional data.

Background: The impact of the order of treatment with checkpoint inhibitors or BRAF/MEK inhibitors on the development of brain metastases in patients with metastatic unresectable V600-mutant melanoma is unknown. The SECOMBIT trial examined the impact of the order of receipt of these treatments in such patients.

Methods: In this three-arm trial, we reviewed patients without brain metastases who received the BRAF/MEK inhibitors encorafenib and binimetinib until they had progressive disease followed by the immune checkpoint inhibitors ipilimumab and nivolumab (arm A); or treatment with ipilimumab and nivolumab until they had progressive disease followed by encorafenib and binimetinib (arm B); or treatment with encorafenib and binimetinib for 8 weeks followed by ipilimumab and nivolumab until they had progressive disease followed by retreatment with encorafenib arm binimetinib (arm C).

Article Synopsis
  • * Using a combination of proteomic and transcriptomic analyses on tissue samples from 22 patients, they found that certain protein and gene signatures were linked to poorer outcomes, specifically in progression-free survival (PFS) and overall survival (OS).
  • * Patients with low-risk signatures exhibited significantly worse treatment responses, showing that those with higher expression levels of the identified biomarkers had better PFS and OS results, highlighting the importance of these combined biomarkers for predicting patient outcomes.

Most patients with Primary Mediastinal B-Cell Lymphoma (PMBCL) are cured by rituximab and doxorubicin-based immunochemotherapy, with or without radiotherapy. In cases with relapsed and refractory (RR) disease the prognosis was historically poor. Recently, immune checkpoint-based strategies have been shown to be highly effective in patients with RR-PMBCL.

Treatment duration with checkpoint inhibitors must be optimized to prevent unjustified toxicity, but evidence for the management of cutaneous squamous cell carcinoma is lacking. A retrospective study was performed to evaluate the survival of patients with cutaneous squamous cell carcinoma (CSCC) who discontinued cemiplimab due to different causes and without progression. Among 95 patients with CSCC who received cemiplimab, 22 (23%) patients discontinued immunotherapy due to causes other than progression, such as comorbidities, toxicity, complete response or lack of compliance (group that discontinued before censoring [DBC]), then 73 patients had standard treatment scheduled (STS).

Older patients have similar immune checkpoint inhibitor efficacy and rates of adverse events as younger patients, but appear to have decreased tolerability, particularly in the oldest patient cohort (>80 years), often leading to early cessation of therapy. We aimed to determine whether early discontinuation impacts efficacy of anti-PD-1 therapy in patients ≥80 years old. In this retrospective, multicenter, international cohort study, we examined 773 patients with 4 tumor types who were at least 80 years old and treated with anti-PD-1 therapy.

The monocyte-phagocyte system (MPS), including monocytes/macrophages and dendritic cells (DCs), plays a key role in anti-viral immunity. We aimed to analyze the prognostic value of the MPS components on in-hospital mortality in a cohort of 58 patients (M/F; mean age ± SD years) with COVID-19 pneumonia and 22 age- and sex-matched healthy controls. We measured frequencies and absolute numbers of peripheral blood CD169 monocytes, conventional CD1c and CD141 (namely cDC2 and cDC1), and plasmacytoid CD303 DCs by means of multi-parametric flow cytometry.

Article Synopsis
  • Prior to 2021, there was no available data to help choose between BRAF/MEK inhibitors and PD-1/CTLA-4 blockade for treating BRAFV600-mutant melanoma, leading to the SECOMBIT trial to study these options.
  • The trial assessed three treatment sequences: immunotherapy or targeted therapy first, or a combination approach, with the goal of evaluating overall survival.
  • Results indicated that immunotherapy followed by targeted therapy led to better long-term survival, and biomarker analyses suggested that specific genetic mutations may indicate improved outcomes, paving the way for future research on treatment predictions.

Article Synopsis
  • * High baseline NLR correlates with poorer patient prognosis and specific gene signatures associated with inflammation and tumor growth, while low NLR indicates immune activation.
  • * The findings suggest that an increase in NLR relates to a rise in immunosuppressive neutrophils, contributing to a negative impact on treatment outcomes for patients.

Background: Nivolumab is an anti-PD1 antibody that has dramatically improved metastatic melanoma patients' outcomes. Nevertheless, many patients are resistant to PD-1 inhibition, occasionally experiencing severe off-target immune toxicity. In addition, no robust and reproducible biomarkers have yet been validated to identify the correct selection of patients who will benefit from anti-PD-1 treatment avoiding unwanted side effects.

Purpose: No evidence exists as to whether type 2 diabetes mellitus (T2DM) impairs clinical outcome from immune checkpoint inhibitors (ICI) in patients with solid tumors.

Experimental Design: In a large cohort of ICI recipients treated at 21 institutions from June 2014 to June 2020, we studied whether patients on glucose-lowering medications (GLM) for T2DM had shorter overall survival (OS) and progression-free survival (PFS). We used targeted transcriptomics in a subset of patients to explore differences in the tumor microenvironment (TME) of patients with or without diabetes.

Melanoma displays a rising incidence, and the mortality associated with metastatic form remains high. Monoclonal antibodies that block programmed death (PD-1) and PD Ligand 1 (PD-L1) network have revolutionized the history of metastatic disease. PD-L1 is expressed on several immune cells and can be also expressed on human neutrophils (PMNs).
