Positional changes in parotid glands during head and neck radiation therapy
Introduction: Xerostomia is the most common complication due to radiation–induced damage to salivary glands in head and neck cancer radiotherapy and it reduces quality of life. Parotid glands are main glands which they are account for secretion of stimulated saliva. Studies have demonstrated that mean tolerance parotid’s radiation dose under 26-30 Gy result in an increase in t...
متن کاملQuantification of Partial Volume Effects in Salivary Glands SPECT Images after Radiation Therapy of Head and Neck Tumors
Introduction: Radical radiation therapy of head and neck cancers may injure the salivary glands and reduce their function. Single-photon emission computed tomography (SPECT) images maybe used to evaluate function post-therapy. However, accurate quantification is hindered by the partial volume effects (PVEs). The present study involved the introduction of a PVEs quantif...
متن کاملParotid sparing study in head and neck cancer patients receiving bilateral radiation therapy: one-year results.
Many patients with head and neck cancers receive radiation therapy as part of their treatment which frequently causes considerable morbidity, including various degrees of permanent salivary gland dysfunction. Three-dimensional treatment planning [3-DTP] and conformational dose delivery constitute a new therapeutic modality that conforms the high-dose radiation volume to the shape of the tumor v...
متن کامل[Radiation therapy for head and neck cancer].
Radiation therapy is the first choice of treatment for most of the early squamous cell carcinoma of the head and neck. Conventional radiotherapy however, contributes to the high local control rates only for carcinoma of the glottic larynx and the nasopharynx. Squamous cell carcinoma of the other sites cannot be sterilized easily only by external beam radiation therapy alone. Chemoradiotherapy, ...
متن کاملOropharyngeal 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...
