Through our involvement in KEYNOTE-059, we unexpectedly observed durable responses two patients with metastatic gastroesophageal adenocarcinoma (mGEA) who received ramucirumab (anti-VEGFR-2)/paclitaxel after immune checkpoint inhibition (ICI). To assess the reproducibility of this observation, piloted an approach to administer ramucirumab/paclitaxel ICI more patients, and explored changes microenvironment. Nineteen consecutive mGEA followed by ramucirumab/paclitaxel. Most (95%) did not...
Plasma-based circulating cell-free tumor DNA (ctDNA) genomic profiling by next-generation sequencing (NGS)is an emerging diagnostic tool for pancreatic cancer (PC). The impact of detected alterations and variant allele fraction (VAF) in response to systemic treatments outcomes is under investigation.Patients with advanced PC who had ctDNA profiled at time initial diagnosis were retrospectively evaluated. We considered the somatic alteration highest VAF as dominant clone frequency (DCAF). NGS...
PURPOSE Thrombocytopenia is a relatively common dose-limiting toxicity during peptide receptor radionuclide therapy (PRRT) in patients with NET. Although uncommon, some develop persistent cytopenia and eventually therapy-related myeloid neoplasm (t-MN), which has dismal prognosis. As the indications for PRRT are expanding, it important to investigate factors that may predict cytopenias during/after PRRT. We prospectively evaluated prevalence of clonal hematopoiesis (CH) NET undergoing...
