[Ga]Ga-DOTAGA-Glu(FAPi) Shows Enhanced Tumor Uptake and Theranostic Potential in Preclinical PET Imaging.

The use of fibroblast activation protein inhibitors (FAPis) for positron emission tomography (PET) imaging in cancer has garnered significant interest in recent years, yielding promising results in preclinical and clinical settings. FAP is predominantly expressed in pathological conditions such as fibrosis and cancer, making it a compelling target. An optimized approach involves using FAPi homodimers as PET tracers, which enhance tumor uptake and retention, making them more effective candidates for therapy.

Opioid use disorders can be treated with psychosocial interventions which aim to increase quality of life and minimize problems maintaining drug use. In addition, pharmacological treatment with opioid maintenance therapy (OMT) can help minimize morbidity and mortality. The principle for OMT is substituting to another opioid with a more favourable pharmacological profile, primarily buprenorphine or methadone.

Young Danish HPV vaccinated women's knowledge, barriers and facilitators towards cervical cancer screening: A qualitative study.

Cervical cancer occurs more often in under-screened women, and participation rates in cervical cancer screening among young women are worryingly low worldwide. In Denmark only about half the women in their twenties participate in cervical cancer screening. 64-80% of women between 20 and 29 have been HPV vaccinated with a vaccine protecting against 70% of all cervical cancers.

Soluble programmed cell death protein 1 (sPD-1) and the soluble programmed cell death ligands 1 and 2 (sPD-L1 and sPD-L2) in lymphoid malignancies.

Background: The programmed cell death protein 1 (PD-1) and its ligand 1 and 2 (PD-L1/PD-L2) regulate the immune system, and the checkpoint pathway can be exploited by malignant cells to evade anti-tumor immune response. Soluble forms (sPD-1/sPD-L1/sPD-L2) exist in the peripheral blood, but their biological and clinical significance is unclear.

Method: Time-resolved immunofluorometric assay (TRIFMA) and enzyme-linked immunosorbent assay (ELISA) were used to measure sPD-1, sPD-L1, and sPD-L2 levels in serum from 131 lymphoma patients and 22 healthy individuals.

Soluble PD-1 but Not PD-L1 Levels Predict Poor Outcome in Patients with High-Risk Diffuse Large B-Cell Lymphoma.

Interaction of checkpoint receptor programmed death 1 (PD-1) with its ligand 1 (PD-L1) downregulates T cell effector functions and thereby leads to tumor immune escape. Here, we aimed to determine the clinical significance of soluble PD-1 (sPD-1) and soluble PD-L1 (sPD-L1) in patients with diffuse large B-cell lymphoma (DLBCL). We included 121 high-risk DLBCL patients treated in the Nordic NLG-LBC-05 trial with dose-dense immunochemotherapy.

High proportions of PD-1 and PD-L1 leukocytes in classical Hodgkin lymphoma microenvironment are associated with inferior outcome.

Immune checkpoint inhibition targeting the programmed death receptor (PD)-1 pathway is a novel treatment approach in relapsed and refractory classical Hodgkin lymphoma (cHL). Identifying patients with a high risk of treatment failure could support the use of PD-1 inhibitors as front-line treatment. Our aim was to investigate the prognostic impact of PD-1, programmed death-ligand 1 (PD-L1), and PD-L2 in the tumor microenvironment in diagnostic biopsies of patients with cHL.
