Efficacy of FDG-PET for defining gross tumor volume of head and neck cancer
We analyzed the data for 53 patients with histologically proven primary squamous cell carcinoma of the head and neck treated with radiotherapy between February 2006 and August 2009. All patients underwent contrast-enhanced (CE)-CT and (18)F-fluorodeoxyglucose (FDG)-PET before radiation therapy planning (RTP) to define the gross tumor volume (GTV). The PET-based GTV (PET-GTV) for RTP was defined...
متن کاملImpact of primary tumor volume on local control after definitive radiotherapy for head and neck cancer.
BACKGROUND The impact of primary tumor volume (pTV) on local control after definitive radiotherapy (RT) for head and neck squamous cell carcinoma (HNSCC) is unclear. METHODS Pertinent literature was reviewed to address the impact of pTV on local control after definitive RT for HNSCC. RESULTS Reproducibility of pTV calculations is probably influenced by interobserver variability and may be r...
متن کامل18F-FDG PET/CT-based gross tumor volume definition for radiotherapy in head and neck Cancer: a correlation study between suitable uptake value threshold and tumor parameters
BACKGROUND To define a suitable threshold setting for gross tumor volume (GTV) when using 18Fluoro-deoxyglucose positron emission tomography and computed tomogram (PET/CT) for radiotherapy planning in head and neck cancer (HNC). METHODS Fifteen HNC patients prospectively received PET/CT simulation for their radiation treatment planning. Biological target volume (BTV) was derived from PET/CT-b...
متن کاملThe role of tumor volume in radiotherapy of patients with head and neck cancer
The assumption that the larger tumor contains a higher number of clonogenic cells what may deteriorate prognosis of patients treated with RT has been confirmed in many clinical studies. Significant prognostic influence of tumor volume (TV) on radiotherapy (RT) outcome has been found for tumors of different localizations including patients with head and neck cancer (HNC). Although TV usually is ...
متن کاملAutomatic Segmentation of the Gross Tumor Volume in Prostate Carcinoma Using Fuzzy Clustering in Gallium-68 PSMA PET/CT Scan
Introduction: Modern radiotherapy (RT) techniques allow a highly precise deposition of the radiation dose in tumor. So, high conformal tumor doses can be reached while sparing critical organs at risk. Materials and Methods: This study was conducted in three phases. In the first phase; Fourteen patients with primary or recurrent prostate cancer receive Gallium-...
