Background: Although positron emission tomography/computed tomography (PET/CT) findings are prognostic in lung cancer patients, the prognostic value of PET/CT findings in patients with pulmonary metastases has neither been comprehensively investigated nor clarified. The aims of this retrospective study were to evaluate the value of PET/CT and identify novel prognostic indicators for pulmonary metastasectomy. Methods: Between May 2004 and February 2017, 178 patients underwent PET/CT and resection of pulmonary metastases...

OBJECTIVE: The aim of this study was to evaluate fluorine-18-fluorodeoxyglucose (F-FDG) PET/CT for the selection of patients with nonresectable colorectal liver metastases (NCLM) for liver transplantation (LT). In the secondary cancer study, we reported an improved 5-year overall survival in patients treated with LT for NCLM (56%) compared with chemotherapy (9%). However, many patients were rejected for LT owing to the detection of extrahepatic disease at preoperative imaging. PATIENTS AND METHODS: F-FDG PET/CT and contrast-enhanced computed tomography (ceCT) examinations before tentative LT for NCLM were assessed, and findings contraindicating LT were registered...

INTRODUCTION: Colorectal cancer liver metastasis (CRLM) can be cured with surgery. To improve survival, optimal selection of CRLM patients should be done cautiously, which may be facilitated by preoperative [F-18] fluorodeoxyglucose positron emission tomography/computed tomography (18 F-FDG PET/CT). METHODS: A total of 245 patients with CRLM between February 2007 and January 2015 were retrospectively studied. All clinical variables, pathological data, and various PET/CT parameters were correlated with disease-free survival (DFS) and overall survival (OS)...

1) to evaluate efficiencies of gadoxetic acid-enhanced magnetic resonance imaging (Gd-EOB-MRI) for preoperative assessment of liver metastases from colorectal carcinoma, and 2) to compare them with other diagnostic imaging modalities. The subjects of the analysis were outpatients with advanced colorectal cancer who are at risk of developing liver metastases (initial setting: pre-test probability=20%). At initial setting, we performed a decision analysis to calculate numbers of true positive (TP), false negative (FN), false positive (FP) and true negative (TN) test results per 1000 patients of Gd-EOB-MRI and other imaging modalities (conventional contrast agent-enhanced MRI, contrast-enhanced CT and 18 F-FDG PET/CT)...

The US FDA granted accelerated approval to pembrolizumab for microsatellite instability-high and mismatch repair deficient cancers. The response of programmed death-1 blockade in mismatch repair proficiency (pMMR) colorectal cancer is very poor, however, whether such treatment is effective in pMMR nasopharyngeal carcinoma (NPC) remains unknown. We report a case of a 51-year-old man with NPC. PET-CT scan revealed a space-occupying lesion in the left lung, and the pathologic result confirmed the occupying lesion originated from NPC...

BACKGROUND: The assessment of colorectal liver metastases (CRLM) after treatment with chemotherapy is challenging due to morphological and/or functional change without changes in size. The aim of this review was to assess the value of FDG-PET, FDG-PET-CT, CT and MRI in predicting response to chemotherapy in CRLM. METHODS: A systematic review was undertaken based on PRISMA statement. PubMed and Embase were searched up to October 2016 for studies on the accuracy of PET, PET-CT, CT and MRI in predicting RECIST or metabolic response to chemotherapy and/or survival in patients with CRLM...

Background: FDG-avid thyroid incidentalomas (TI) are seen in approximately 2.5% of patients imaged for staging or response assessment of malignancy and represent thyroid cancer in approximately 35% of cases. Consequently, the 2015 ATA guidelines strongly recommend investigation of all FDG-avid nodules ≥1cm with US and fine needle aspiration cytology (FNA). This study aims to assess the overall and thyroid cancer specific survival in a large cohort of patients with FDG-avid TI with long-term follow-up to assess the validity of this approach...

BACKGROUND: Increased use of PET/CT scans in oncology patients has raised detection of Colorectal incidentalomas (CIs). The frequency and diagnostic outcomes of identifying these lesions in melanoma patients have not previously been studied. This studies primary objective was to determine the prevalence of CIs found on PET/CT scans in melanoma patients. The secondary objectives were to correlate the PET/CT findings with the pathology found at colonoscopy, and identify which patients were referred for colonoscopy...
