摘要
Background: A prospective clinical analysis was carried out to assess the diagnostic and therapeutic impact of fluorodeoxyglucose positron emission tomography (FDG-PET) on planning radiotherapy in patients with advanced head and neck cancer in AJCC Stages III/IV. Methods: From July 1999 to May 2004 FDG-PET was performed in 49 patients prior to radiotherapy for exclusion of systemic disease, synchronous second or unknown primary tumors. Results: 45/49 (91.9%) FDG-PET findings could be confirmed in comparison with conventional imaging and the clinical follow up of 9.5 months. 21/49 FDG-PET (42.8%) yielded new diagnostic information with therapeutic implications in 20/49 (40.8%) cases. The therapy strategy was changed in 14/49 patients, minor modifications in the portal design occurred in 6/49 patients. 9/49 (18.3%) FDG-PET supported a curative strategy, 11/49 (22.4%) a palliative one. Conclusions: FDG-PET is a useful and important diagnostic tool mainly for exclusion of systemic disease in advanced head and neck cancer, thus influencing radiotherapy in 20/49 (40.8%) of patients investigated in our study.
