Several studies have demonstrated that patients who experience immune-related adverse events (irAE) as a result of immunotherapy treatment, exhibit significantly improved outcomes compared to patients without toxicity. Data regarding the impact of specific irAE is, however, currently lacking. This is a real-world single-site cohort of 415 advanced melanoma patients who were treated with immunotherapy as first-line between 2014 and 2020, with a median follow-up of 24.

Introduction: Immunotherapy has revolutionized the prognosis of patients with metastatic melanoma. To date, the most active regimen is the combination of ipilimumab + nivolumab (ipi-nivo) achieving a response rate of nearly 60% and a median survival (OS) of 6 years. However, approximately 40% of patients experience primary resistance, while around 50% experience secondary resistance, highlighting the need for an effective second-line treatment option The recently published results on the use of lenvatinib + pembrolizumab in the advanced line setting led to the adoption of this regimen at our institution.

Immunotherapy has revolutionized the treatment of advanced melanoma. Because the pathways mediating resistance to immunotherapy are largely unknown, we conducted transcriptome profiling of preimmunotherapy tumor biopsies from patients with melanoma that received PD-1 blockade or adoptive cell therapy with tumor-infiltrating lymphocytes. We identified two melanoma-intrinsic, mutually exclusive gene programs, which were controlled by IFNγ and MYC, and the association with immunotherapy outcome.

Background: Primary analysis of the phase 3 IMspire150 study showed improved investigator-assessed progression-free survival with first-line atezolizumab, vemurafenib, and cobimetinib (atezolizumab group) versus placebo, vemurafenib, and cobimetinib (control group) in patients with BRAF mutation-positive melanoma. With a median follow-up of 18·9 months (IQR 10·4-23·8) at the primary analysis, overall survival data were immature. Here, we report the results from the second, prespecified, interim overall survival analysis.

Introduction: Uveal melanoma (UM) is a subtype of melanoma arising from the ocular region. Despite various local therapies available, a significant portion of patients develop distant metastases, primarily to the liver. While cutaneous melanoma is very sensitive to immunotherapy, UM is known to be less responsive and patients were excluded from pivotal clinical trials.

Article Synopsis
  • A phase III trial, CheckMate 915, compared the effectiveness of combining nivolumab and ipilimumab with using nivolumab alone for treating high-risk resected melanoma patients.
  • The study involved 1,833 participants, who were randomly assigned to either the combination therapy or nivolumab alone, focusing on recurrence-free survival (RFS) as the primary outcome.
  • Results showed no significant difference in RFS between the two groups, with similar 24-month RFS rates; however, the combination therapy had higher rates of severe adverse events, reaffirming nivolumab as a standard treatment for melanoma adjuvant therapy.

The COVID-19 pandemic has not only accounted for a substantial number of deaths in the United States but also deleterious mental health outcomes. We integrated multiple lines of previous research to better understand psychological strengths and difficulties in the face of the pandemic by testing a moderated mediation model that posited that rumination mediates the relationship between COVID-related stress and depression, and mindfulness moderates the relationship between COVID-related stress and rumination. The participants were 196 young adults (79.

Article Synopsis
  • The study investigates how melanoma cells interact with T cells and how this interaction enhances the movement of new T cells towards tumors, highlighting the importance of HLA class I and IFNγ in this process.
  • Analysis of melanoma samples revealed that the ADAR1-p150 isoform is significantly linked to immune infiltration, with higher levels observed following immunotherapy and correlating with CD8+ T cell presence.
  • Findings suggest that the presence of T cells stimulates melanoma cells to produce ADAR1-p150, which plays a crucial role in promoting T cell migration through the regulation of chemokine secretion, thus impacting tumor immune responses.

Purpose: Guidelines addressing melanoma in-transit metastasis (ITM) recommend immune checkpoint inhibitors (ICI) as a first-line treatment option, despite the fact that there are no efficacy data available from prospective trials for exclusively ITM disease. The study aims to analyze the outcome of patients with ITM treated with ICI based on data from a large cohort of patients treated at international referral clinics.

Methods: A multicenter retrospective cohort study of patients treated between January 2015 and December 2020 from Australia, Europe, and the USA, evaluating treatment with ICI for ITM with or without nodal involvement (AJCC8 N1c, N2c, and N3c) and without distant disease (M0).

Despite the high rates of complete remission following chimeric antigen receptor (CAR) T cell therapy, its full capacity is currently limited by the generation of dysfunctional CAR T cells. Senescent or exhausted CAR T cells possess poor targeting and effector functions, as well as impaired cell proliferation and persistence in vivo. Strategies to detect, prevent or reverse T cell exhaustion are therefore required in order to enhance the effectiveness of CAR T immunotherapy.

Background: Immunotherapy has revolutionized outcomes for melanoma patients, by significantly prolonging survival and probably even curing a fraction of metastatic patients. In daily practice, treatment for responding patients is often discontinued due to treatment-limiting toxicity, or electively, following a major tumor response. To date, the criteria for a safe stop and the optimal duration of treatment remain unclear.

Purpose: Although patients with unresectable or metastatic melanoma can experience long-term survival with BRAF- and MEK-targeted agents or immune checkpoint inhibitors over 5 years, resistance develops in most patients. There is a distinct lack of pretherapeutic biomarkers to identify which patients are likely to benefit from each therapy type. Most research has focused on the predictive role of T cells in antitumor responses as opposed to B cells.
