Strategies targeting intracellular negative regulators such as immune checkpoint inhibitors (ICPIs) have demonstrated significant antitumor activity across a wide range of solid tumors. In the clinical practice, the radiological effect of immunotherapeutic agents has raised several more relevant and complex challenges for the determination of their imaging-based response at single patient level. Accordingly, it has been suggested that the conventional Response Evaluation Criteria in Solid Tumors assessment alone, based on dimensional evaluation provided by computed tomography (CT), tends to underestimate the benefit of ICPIs at least in a subset of patients, supporting the need of immune-related response criteria...

BACKGROUND: The diagnosis of malignant diseases worldwide has been determined using (18)F-fluorodeoxyglucose positron emission tomography (FDG-PET). Glucose transporter type 1 (Glut-1) is a key protein associated with the accumulation of FDG in cancer cells. This study evaluated the relationship between Glut-1 expression and FDG accumulation to determine the usefulness of FDG-PET for prediction of long-term outcomes of pancreatic cancer. METHODS: The expression of Glut-1 was immunohistochemically examined in 138 surgically resected pancreatic cancer specimens...

A 65-year-old man had undergone high anterior resection for rectal cancer. Seven years after the surgery, a liver metastasis was identified, and the metastasis was surgically resected. A year after the liver surgery, blood testing showed high carcinoembryonic antigen(CEA). A fluorodeoxyglucose(FDG) / -positron emission tomography(PET)/CT examination showed a high FDG accumulation at the rectal anastomosis site, and we diagnosed local recurrence of rectal cancer and prostate invasion. Because there were no distant metastases, he underwent laparoscopic lower anterior resection, radical prostatectomy, and ileostomy...

Background Boron neutron capture therapy (BNCT) is a molecular radiation therapy approach based on the (10)B (n, α) (7)Li nuclear reaction in cancer cells. In BNCT, delivery of (10)B in the form of 4-borono-phenylalanine conjugated with fructose (BPA-fr) to the cancer cells is important. The PET tracer 4-borono-2-18F-fluoro-phenylalanine (FBPA) has been used to predict the accumulation of BPA-fr before BNCT. Purpose To determine the biodistribution and dosimetric parameters in 18F-BPA PET/CT studies. Material and Methods Human biokinetic data were obtained during clinical 18F-BPA PET studies between February and June 2015 at one institution...

Positron emission tomography (PET) with (18)F-fluorodeoxyglucose (FDG) is a diagnostic tool to evaluate metabolic activity by measuring accumulation of FDG, an analogue of glucose, and has been widely used for detecting small tumors, monitoring treatment response and predicting patients' prognosis in a variety of cancers. However, the molecular mechanism of FDG accumulation into tumors remains to be investigated. It is well-known that most cancers are metabolically active with elevated glucose metabolism, a phenomenon known as the Warburg effect...

Choline is a new positron emission tomography (PET) tracer useful for detection of prostate cancer and metastatic lesions. We report a 70-year-old man with prostate cancer and multiple abdominal, pelvic, and inguinal node metastases. PET scans demonstrated accumulation of (11)C-choline in the primary tumor and lymph node metastases but no accumulation of (18)F-FDG. Choline PET/computed tomography may be useful for diagnosis of advanced prostate cancer with suspected metastatic lesions and treatment planning...

INTRODUCTION: Immune cells utilize acetylcholine as a paracrine-signaling molecule. Many white blood cells express components of the cholinergic signaling pathway, and these are up-regulated when immune cells are activated. However, in vivo molecular imaging of cholinergic signaling in the context of inflammation has not previously been investigated. METHODS: We performed positron emission tomography (PET) using the glucose analogue 18F-FDG, and 11C-donepezil and 18F-FEOBV, markers of acetylcholinesterase and the vesicular acetylcholine transporter, respectively...

BACKGROUND: Hibernoma is a rare, benign, soft tissue tumor arising from brown fat that cannot be distinguished from other lipogenic tumors on computed tomography and magnetic resonance imaging (MRI) scans. On the other hand, the image of hibernoma on (18)F-fluorodeoxyglucose positron emission tomography ((18)F-FDG-PET) is different from that of other lipogenic tumors. However, fewer studies have investigated the typical features of hibernoma on PET scans. We present the case of a hibernoma that was incidentally detected on (18)F-FDG-PET...

Purpose: The current lack of tools for easy assessment of cancer stem cells (CSC) prevents the development of therapeutic strategies for hepatocellular carcinoma (HCC). We previously reported that keratin 19 (K19) is a novel HCC-CSC marker and that PET with (18)F-fluorodeoxyglucose ((18)F-FDG) is an effective method for predicting postoperative outcome in hepatocellular carcinoma. Herein, we examined whether K19(+) HCC-CSCs can be tracked using (18)F-FDG-PET.Experimental Design: K19 and glucose transporter-1 (GLUT1) expression was evaluated by IHC in 98 hepatocellular carcinoma patients who underwent (18)F-FDG-PET scans before primary tumor resection...

INTRODUCTION: High uptake of [(18)F]-2-fluorodeoxyglucose ([(18)F]FDG) by inflammatory cells is a frequent cause of false positive results in [(18)F]FDG-positron-emission tomography (PET) for cancer diagnostics. Similar to cancer cells, immune cells undergo significant increases in glucose utilization following activation, e.g., in infectious diseases or after vaccination during cancer therapy. The aim of this study was to quantify certain immune effects in vitro and in vivo by [(18)F]FDG-PET after stimulation with TLR ligands and specific antibodies...
