Aims: This multicenter phase II trial evaluates the efficacy of everolimus in poor prognosis grade 2 (G2) pancreatic neuroendocrine tumors (PNETs), defined by 2-[fluorine-18]fluoro-2-deoxy-d-glucose (FDG) positron-emission tomography (PET) avidity. FDG-PET avidity in NETs is associated with a significantly higher risk of death, outperforming Ki-67 index or liver metastases as a poor prognostic factor. We hypothesized that everolimus has efficacy in patients with FDG-PET-avid G2 PNETs and prospectively evaluated progression-free survival (PFS) and response in the first-line setting.
Methods: Patients with FDG-PET-avid G2 advanced PNET received everolimus 10 mg daily until disease progression. Patients were staged every 12 weeks with CT/MRI and FDG-PET and every 24 weeks with Gallium 68 (68Ga) 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid (DOTA)-octreotate (DOTATATE, GaTate) PET. The primary endpoint was PFS at 6 months. Overall survival rate, PET/structural imaging response and toxicity were also measured.
Results: Nine patients were accrued from December 2012 to February 2015. Median treatment duration was 13.8 months. The estimated PFS rate at 6 months was 78%. The best response on CT/MRI was stable disease in nine patients (100%) and partial response on FDG-PET in five patients (55.5%). Treatment-related adverse effects were consistent with previous studies of everolimus.
Conclusion: Everolimus is active with prolonged disease control in poor prognosis FDG-avid G2 PNETs. Treatment individualization based on functional imaging warrants further evaluation.

Background: Cardiac involvement in amyloid light chain (AL) amyloidosis significantly influences prognosis, necessitating timely diagnosis and meticulous risk stratification.
Objectives: This prospective study aimed to delineate the molecular phenotypes of AL cardiac amyloidosis (AL-CA) by characterizing fibro-amyloid deposition using F-florbetapir and gallium-68-labeled fibroblast activation protein inhibitor-04 (Ga-FAPI-04) positron emission tomography (PET)/computed tomography (CT) imaging. The authors also proposed a novel molecular stratification methodology for prognosis.

mRNA delivered using lipid nanoparticles (LNPs) has become an important subunit vaccine modality, but mechanisms of action for mRNA vaccines remain incompletely understood. Here, we synthesized a metal chelator-lipid conjugate enabling positron emission tomography (PET) tracer labeling of LNP/mRNA vaccines for quantitative visualization of vaccine trafficking in live mice and non-human primates (NHPs).

The duration of the response to radiotherapy-related treatment is a critical prognostic indicator for patients with nasopharyngeal carcinoma (NPC). Persistent tumor status, including residual tumor presence and early recurrence, is associated with poorer survival outcomes. To address this, we developed a prediction model to identify patients at a high risk of persistent tumor status prior to initiating treatment.

Background: To examine the feasibility and safety of the SENSEI drop-in gamma probe for robot-assisted, prostate-specific membrane antigen (PSMA)-radioguided salvage surgery (RGS) in lymph node or local oligorecurrent prostate cancer (PCa), detected via PSMA positron emission tomography/computed tomography (PET/CT).
Methods: The first thirteen patients with pelvic oligorecurrent PCa who underwent [Tc]Tc-PSMA-I&S RGS using the SENSEI drop-in gamma probe at the Martini-Klinik (February-June 2024) were retrospectively analyzed. Radioactivity measurements in counts per second (CPS) as absolute values or ratios (CPS of tumor specimens/mean CPS from the patients' benign tissues) were correlated with preoperative imaging and pathological findings (benign/malignant, lesion size).
