Evaluation of PET/MRI for Tumor Volume Delineation for Head and Neck Cancer

INTRODUCTION Computed tomography (CT), combined positron emitted tomography and CT (PET/CT), and magnetic resonance imaging (MRI) are commonly used in head and neck radiation planning. Hybrid PET/MRI has garnered attention for potential added value in cancer staging and treatment planning. Herein, we compare PET/MRI vs. planning CT for head and neck cancer gross tumor volume (GTV) delineation. ...

Primary tumor volume delineation in head and neck cancer: missing the tip of the iceberg?

BACKGROUND The aim was to evaluate the geometric and corresponding dosimetric differences between two delineation strategies for head and neck tumors neighboring air cavities. METHODS Primary gross and clinical tumor volumes (GTV and CTV) of 14 patients with oropharynx or larynx tumors were contoured using a soft tissue window (S). In a second strategy, the same volumes were contoured with an...

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...

Oropharyngeal candidiasis and resistance to antifungal drugs in patients receiving radiation for head and neck cancer

BACKGROUND: Oropharyngeal candidiasis is a common infection in patient receiving radiotherapy for head and neck cancer. Accurate and rapid identification of candida species is very important in clinical laboratory, because the incidence of candidiasis continues to rise after radiotherapy. The genus Candida has about 154 species that show different level of resistance to antifungal drugs and hav...

Impact 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...
