PURPOSE: The prognostic value of the tumor-to-liver uptake ratio (TLR) from 18-fluoro-2-deoxyglucose positron emission tomography/computed tomography ((18)F-FDG-PET/CT) in the early stage of colorectal cancer (CRC) is unclear. Notably, some stage IIA CRC patients experience early recurrence even after curative resection and might benefit from neoadjuvant or adjuvant chemotherapy. This study aims to evaluate whether elevated TLR from (18)F-FDG-PET/CT can predict poor prognosis in stage IIA CRC patients undergoing curative resection...

Physical measurement of tumor volume reduction is the most commonly used approach to assess tumor progression and treatment efficacy in mouse tumor models. However, it is relatively insensitive, and often requires long treatment courses to achieve gross physical tumor destruction. As alternatives, several non-invasive imaging methods such as bioluminescence imaging (BLI), fluorescence imaging (FLI) and positron emission tomography (PET) have been developed for more accurate measurement. As tumors have elevated glucose metabolism, 18F-fludeoxyglucose (18F-FDG) has become a sensitive PET imaging tracer for cancer detection, diagnosis, and efficacy assessment by measuring alterations in glucose metabolism...

Several reports have described dramatic increase over recent decades in the incidence of thyroid cancer, even as thyroid cancer-related mortality rates have not changed substantially. Nevertheless, in several retrospective studies the incidence of malignancy in focal (18)F-fluorodeoxyglucose (FDG) thyroid uptake discovered on whole body (18)F-FDG PET/CT, carried out for non-thyroid cancers, is 13-64%. Our aim was to design a practical algorithm for management of an increasing number of thyroid incidentalomas, identified by (18)F-FDG PET/CT...

A diagnosis of ductal carcinoma in situ (DCIS) at needle biopsy often changes to that of invasive ductal carcinoma as the definitive pathological diagnosis following the surgical procedure. The present study sought to identify the factors associated with invasive disease in cases diagnosed as DCIS on needle biopsy by analyzing (18)F-fluorodeoxyglucose-proton emission tomography (FDG-PET) findings. The present study retrospectively investigated the cases of 24 consecutive patients with primary breast cancer who were preoperatively diagnosed with DCIS by needle biopsy...

Purpose: Late-stage, unresectable pancreatic ductal adenocarcinoma (PDAC) is largely resistant to chemotherapy and consequently has a very poor 5-year survival rate of < 5%. The ability to assess the efficacy of a treatment soon after its initiation would enable rapid switching to potentially more effective therapies if the current treatment is found to be futile. We have evaluated the ability of the PET imaging agent, (89)Zr-anti-γH2AX-TAT, to monitor DNA damage in response to fluouracil (5-FU), gemcitabine, or capecitabine treatment in a mouse model of pancreatic cancer...

BACKGROUND: To identify the radio-resistant subvolumes in pretreatment FDG-PET by mapping the spatial location of the origin of tumor recurrence after IMRT for head-and-neck squamous cell cancer to the pretreatment FDG-PET/CT. METHODS: Patients with local/regional recurrence after IMRT with available FDG-PET/CT and post-failure CT were included. For each patient, both pre-therapy PET/CT and recurrence CT were co-registered with the planning CT (pCT). A 4-mm radius was added to the centroid of mapped recurrence growth target volumes (rGTV's) to create recurrence nidus-volumes (NVs)...

The molecular bases for sex differences in cancer remain undefined and how to incorporate them into risk stratification remains undetermined. Given sex differences in metabolism and the inverse correlation between fluorodeoxyglucose (FDG) uptake and survival, we hypothesized that glycolytic phenotyping would improve glioma subtyping. Using retrospectively acquired lower-grade glioma (LGG) transcriptome data from The Cancer Genome Atlas (TCGA), we discovered male-specific decreased survival resulting from glycolytic gene overexpression...

The aim of this study was to describe the influence of HIV infection on the staging of gastric cancer by using positron emission tomography/computed tomography (PET/CT) imaging. We treated a patient with local advanced gastric cancer. PET/CT showed an unusual hypermetabolic activity of lymph nodes, and the patient was later found to be HIV-positive. PET/CT scans in cancer staging of patients with chronic HIV infection may show advanced stage disease. Spread of primary tumor to unusual sites should be a warning sign for the possible concurrent diseases...
