Hexokinase is thought to be one of the key factors of glucose catabolism in the cell. The aim of this study was to investigate the relationship between HK-II expression and 18F-fluoro-2-deoxy-D-glucose (FDG) uptake in human untreated oral squamous cell carcinoma (OSCC). Pre-operatively FDG positron emission tomography (PET) was performed 60 min after FDG injection in all the patients. Maximum standardized uptake value (SUV) was used for evaluation of tumor FDG uptake. Tumor sections were stained immunohistochemically for HK-II. All the tumor sections stained positive for HK-II. Eighteen (95%) tumors in HK-II showed immunostained positive area >50%. HK-II findings revealed eleven (58%) tumors with strong intensity, six (32%) with moderate intensity and two with weak intensity (10%). There was no statistically significant correlation between SUV and the expression of HK-II (p = 0.46). In conclusion, OSCC showed increased FDG accumulation and overexpression of HK-II. However, we did not find any significant relationship between high FDG uptake and overexpression of HK-II in this patient population, and thus other properties need to be evaluated in order to elucidate key factors responsible for FDG activity in OSCC.

Elevated protein lactylation promotes immunosuppressive microenvironment and therapeutic resistance in pancreatic ductal adenocarcinoma.

Metabolic reprogramming shapes tumor microenvironment (TME) and may lead to immunotherapy resistance in pancreatic ductal adenocarcinoma (PDAC). Elucidating the impact of pancreatic cancer cell metabolism in the TME is essential to therapeutic interventions. "Immune cold" PDAC is characterized by elevated lactate levels resulting from tumor cell metabolism, abundance of pro-tumor macrophages, and reduced cytotoxic T cell in the TME.

Purpose: To evaluate the diagnostic accuracy and clinical impact of fibroblast activation protein (FAP)-targeted PET/CT imaging in primary and metastatic breast cancer and compare the results with those of standard-of-care imaging (SCI) and [F]FDG PET/CT.
Methods: We prospectively analyzed patients with diagnosed or suspected breast cancer who underwent concomitant FAP-targeted PET/CT (radiotracers including either [Ga]Ga-FAPI-46 or [F]FAPI-42) and [F]FDG PET/CT scans from June 2020 to January 2024 at two medical centers. Breast ultrasound (US) imaging was performed in all treatment-naïve patients as SCI.
One-day dual-tracer examination in neuroendocrine neoplasms: a real advantage of low activity LAFOV PET imaging.

Purpose: Somatostatin receptor (SSTR)-PET is crucial for effective treatment stratification of neuroendocrine neoplasms (NENs). In highly proliferating or poorly differentiated NENs, dual-tracer approaches using additional [F]FDG PET can effectively identify SSTR-negative disease, usually requiring separate imaging sessions. We evaluated the feasibility of a one-day dual-tracer imaging protocol with a low activity [F]FDG PET followed by an SSTR-PET using the recently introduced [F]SiFAlin-TATE tracer in a long axial field-of-view (LAFOV) PET/CT scanner and its implications in patient management.

Background And Aims: Patients with head and neck cancer (HNC) are often malnourished with a low muscular mass at the outset of management. This is thought to be mainly due to poor nutritional intake. The aim of this study was to assess the correlation between tumor metabolic activity, inflammatory status and body composition in HNC patients.

Klippel-Feil syndrome (KFS) is a rare congenital disorder characterized by the fusion of cervical vertebrae, with a clinical presentation that can vary widely due to genetic and phenotypic diversity. While KFS can occur as an isolated anomaly, it is often associated with other congenital conditions, such as Sprengel deformity, which may present with or without an omovertebral bone, complicating diagnosis and management. This particular case also involves diffuse large B-cell lymphoma (DLBCL), the most common subtype of non-Hodgkin lymphoma.
