Longitudinal blood immune-inflammatory and radiomic profiling to decode different patterns of acquired resistance to immunotherapy in patients with NSCLC.

Purpose: To uncover the underpinnings of acquired resistance (AR) to immunotherapy (IO), we determined whether distinctive clinico-pathological, radiomic and peripheral blood (PB) immune-inflammatory features reflect oligo- and systemic (sys)-AR in advanced NSCLC patients undergoing immune checkpoints inhibitors.

Experimental Design: On 105 consecutive IO-treated advanced NSCLC, PB immunophenotypes, cytokines and CT-derived radiomic features (RFs), extracted from primary and merged metastatic lesions, were prospectively collected at baseline (T0) and first disease assessment (T1, 9-12 weeks), and their delta (Δ) variation [(T1-T0)/T0] computed. AR, defined as progression after initial response (complete/partial) or stable disease ≥ 6 months, was subdivided according to the number of new and/or progressive lesions in oligoAR (≤3) and sysAR (>3).

CD26 Is Differentially Expressed throughout the Life Cycle of Infantile Hemangiomas and Characterizes the Proliferative Phase.

Infantile hemangiomas (IHs) are benign vascular neoplasms of childhood (prevalence 5-10%) due to the abnormal proliferation of endothelial cells. IHs are characterized by a peculiar natural life cycle enclosing three phases: proliferative (≤12 months), involuting (≥13 months), and involuted (up to 4-7 years). The mechanisms underlying this neoplastic disease still remain uncovered.

Differential impact of lipid profile according to neutrophil-to-lymphocyte ratio status in patients with advanced cancer treated with immunotherapy.

To investigate the different impact of each component of lipid profile in advanced cancer patients treated with immune checkpoints inhibitors (ICIs) according to neutrophil-to-lymphocyte ratio (NLR) value. We retrospectively collected total cholesterol (TC), triglycerides (TGs), low-density lipoproteins (LDL), high-density lipoproteins (HDL). 407 patients were enrolled.

Intersecting Blood Cytokines With Cholesterol Parameters to Profile Patients With Advanced Solid Tumors Receiving Immune Checkpoint Inhibitors.

The study investigated the relationship between serum proinflammatory cytokine levels, cholesterol metabolism, and clinical outcome in cancer patients undergoing immune checkpoint inhibitors (ICIs). Peripheral blood was collected before therapy from ICI-treated advanced cancer patients. We retrospectively assessed plasma total cholesterol (TC), ABCA1- and ABCG1-mediated cholesterol efflux (CE), passive diffusion (PD), cholesterol loading capacity (CLC), and serum IL-6, IL-10, and TNF-α.
