Safety and efficacy of immune checkpoint therapy for the treatment of patients with cardiac metastasis: a multicenter international retrospective study.
Abstract Background: Data on the safety profiles and clinical outcomes of patients with solid tumors and cardiac metastasis treated with immune checkpoint inhibitors (ICIs) are limited. Methods: This is an international multicenter retrospective study of patients with cancer and cardiac metastasis at baseline. Patients who had received ≥1 dose of ICI were included. Treatment-related adverse events (trAEs) were graded per Common Terminology Criteria for Adverse Event V.5.0. Objective response rates (ORR) were evaluated by Response Evaluation Criteria in Solid Tumors V.1.1 when available. Overall survival (OS) and progression-free survival (PFS) were estimated by the Kaplan-Meier method. Results: Among 110 pts, median age [...]
Neoadjuvant triplet immune checkpoint blockade in newly diagnosed glioblastoma.
Abstract Glioblastoma (GBM) is an aggressive primary adult brain tumor that rapidly recurs after standard-of-care treatments, including surgery, chemotherapy and radiotherapy. While immune checkpoint inhibitor therapies have transformed outcomes in many tumor types, particularly when used neoadjuvantly or as a first-line treatment, including in melanoma brain metastases, they have shown limited efficacy in patients with resected or recurrent GBM. The lack of efficacy has been attributed to the scarcity of tumor-infiltrating lymphocytes (TILs), an immunosuppressive tumor microenvironment and low tumor mutation burden typical of GBM tumors, plus exclusion of large molecules from the brain parenchyma. We hypothesized that upfront [...]
Clinical outcomes and management following progressive disease with anti-PD-(L)1 therapy in patients with advanced Merkel Cell Carcinoma.
Abstract Aim: Merkel Cell Carcinoma (MCC) is a rare skin cancer with a rising incidence worldwide. Anti-programmed death-1/ligand-1 (anti-PD-(L)1) therapies are effective for the treatment of advanced MCC. This study examines patterns of response / progression of advanced MCC to anti-PD-(L)1 therapies and describes subsequent management. Method: This is a multi-centre international retrospective cohort study with data collected up to May 2023 from 17 centres across 6 countries. Outcomes included objective response rate (ORR), duration of response (DOR), progression-free survival (PFS), and overall survival (OS) for anti-PD-(L)1 and subsequent therapy. Results: One-hundred and eighty-five advanced MCC patients received anti-PD-(L)1 therapy. At median [...]
A scoping review of factors influencing the implementation of liquid biopsy for cancer care.
Abstract Background: Liquid biopsy (LB) offers a promising, minimally invasive alternative to traditional tissue biopsies in cancer care, enabling real-time monitoring and personalized treatment. Despite its potential, the routine implementation of LB in clinical practice faces significant challenges. This scoping review examines the barriers and facilitators influencing the implementation of liquid biopsies into standard cancer care. Methods: Four academic databases (PubMed, Scopus, Embase, and Web of Science) were systematically searched without language restrictions. We included peer-reviewed articles that were published between January 2019 and March 2024 that focused on the implementation of LB in cancer care or described barriers and facilitators [...]
Prognostic and predictive value of metformin in the European Organisation for Research and Treatment of Cancer 1325/KEYNOTE-054 phase III trial of pembrolizumab versus placebo in resected high-risk stage III melanoma.
Abstract Background: Metformin is a commonly prescribed and well-tolerated medication. In laboratory studies, metformin suppresses BRAF wild-type melanoma cells but accelerates the growth of BRAF-mutated cells. This study investigated the prognostic and predictive value of metformin, including with respect to BRAF mutation status, in the European Organisation for Research and Treatment of Cancer 1325/KEYNOTE-054 randomised controlled trial. Methods: Patients with resected high-risk stage IIIA, IIIB, or IIIC melanoma received 200 mg of pembrolizumab (n = 514) or placebo (n = 505) every 3 weeks for twelve months. Pembrolizumab prolonged recurrence-free survival (RFS) and distant metastasis-free survival (DMFS) at approximately 42 months [...]

Phase Ib Study of Immunocytokine Simlukafusp Alfa (FAP-IL2v) Combined with Pembrolizumab for Treatment of Advanced and/or Metastatic Melanoma.
Abstract Purpose: This study explored the combination of fibroblast activation protein (FAP) IL2 variant (FAP-IL2v), a novel immune-cytokine, with pembrolizumab in patients with advanced and/or metastatic melanoma. Patients and methods: This open-label, multicenter, phase Ib clinical study (NCT03875079) evaluated the safety, tolerability, pharmacodynamics, pharmacokinetics, and antitumor activity of FAP-IL2v (simlukafusp alfa, RO6874281) in combination with pembrolizumab. Patients with advanced and/or metastatic melanoma were either checkpoint inhibitor (CPI)-naïve or CPI-experienced. Patients received 10 mg FAP-IL2v either continuously once every 3 weeks (Q3W) or in an induction/maintenance setting consisting of a 3-week induction phase with weekly (QW) dosing followed by continuous Q3W dosing. [...]
Adjuvant Pembrolizumab in Stage II Melanoma: Outcomes by Primary Tumor Location in the Randomized, Double-Blind, Phase III KEYNOTE-716 Trial.
Abstract Background: Previous results from the KEYNOTE-716 trial demonstrated significantly improved recurrence-free survival (RFS) and distant metastasis-free survival (DMFS) with adjuvant pembrolizumab versus placebo in patients with resected stage IIB or IIC melanoma. We present a post hoc analysis of efficacy according to primary tumor location. Methods: KEYNOTE-716 (NCT03553836) is a randomized, multicenter, double-blind, phase III study. Patients aged ≥ 12 years with newly diagnosed, resected stage IIB or IIC melanoma (sentinel node-negative) were randomly assigned (1:1) to pembrolizumab 200 mg every 3 weeks (2 mg/kg up to 200 mg for pediatric patients) or placebo. This post hoc analysis evaluated RFS [...]
