UNLABELLED Predicting outcome after aggressive therapy for advanced rectal cancer remains difficult. (18)F-FDG PET has emerged as a valid method for predicting patient outcomes after therapy in an increasing number of cancers. We evaluated the prognostic information obtained from the degree of change in tumor (18)F-FDG PET uptake induced by chemoradiation(More)
BACKGROUND Combined positron emission tomography (PET)/computed tomography (CT) using fluorine-18 fluorodeoxyglucose (FDG) is an exciting technique for cancer evaluation, but false-positive results are a recognized limitation. The aim of the study was to evaluate how oncologists deal with focal extrathyroidal FDG abnormalities considered by imaging(More)
The purpose of this study was to evaluate the impact of FDG-PET following chemoradiotherapy (CRT) on treatment planning and survival in patients with oesophageal cancer (OC). Fifty-three consecutive OC patients had a post-treatment PET scan to evaluate tumour response to CRT prior to possible surgery. Baseline pre-CRT PET was performed in 33 patients.(More)
BACKGROUND & OBJECTIVE Fluorine-18 fluorodeoxyglucose ((18)F-FDG) PET/CT could increase the accuracy of diagnosis, staging, and treatment effectiveness monitoring of many malignant diseases, such as lung cancer and esophageal cancer. This study was to evaluate the clinical application of (18)F-FDG PET/CT to the staging, restaging, and treatment(More)
PURPOSE Changes in F-18 fluorodeoxyglucose (FDG) uptake in normal tissues after chemoradiation therapy (CRT) potentially limit the ability of positron emission tomography (PET) to provide early assessment of therapeutic response. This study evaluated whether such changes negatively impact interpretation of posttherapy PET performed within 6 weeks of CRT(More)
PURPOSE The influence of positron emission tomography in the management of recurrent rectal cancer is well established but its role in primary rectal cancer remains uncertain. This study therefore prospectively assesses the impact of position emission tomography scanning on the management of primary rectal cancer. METHODS Forty-six patients with advanced(More)
The aim of this prospective pilot study in patients with suspected or known brain tumour was to establish the diagnostic value of O-(2-[(18)F]-fluoroethyl)-L-tyrosine (FET) positron emission tomography (PET) when compared to fluorine-18 fluorodeoxyglucose (FDG) PET. Twenty-five FET PET and FDG PET scans were performed on 21 consecutive patients within 24(More)
UNLABELLED The aim of this study is to evaluate the incremental staging information, management impact, and prognostic stratification of PET/CT in the primary staging of esophageal cancer in a cohort of patients with mature survival data. METHODS Between July 2002 and June 2005, 139 consecutive patients with newly diagnosed esophageal cancer underwent(More)
OBJECTIVE The optimal method of assessing disease distribution in endometrial cancer is widely debated. Knowledge of disease distribution assists in planning adjuvant radiotherapy; in this study we used positron emission tomography/computed tomography (PET/CT) to assess disease distribution before radiotherapy. METHODS Seventy-three consecutive patients(More)
PURPOSE Concomitant chemoradiotherapy (CRT) increases survival rates compared with radical radiotherapy alone (RT) in Stage III non-small-cell lung cancer (NSCLC), as a result of improved local control. The effect of CRT on local control in Stage I NSCLC is less well documented. We retrospectively reviewed local control and survival following CRT or RT for(More)
