[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...

متن کاملIntraoperative radiation therapy for recurrent head and neck cancer.
Forty-seven patients with recurrent head and neck cancer in a previously irradiated field were treated with surgical resection and intraoperative radiation therapy (IORT). Recurrent disease occurred at a median of 18 months from primary treatment, and was at the primary tumor site in 31 and metastatic to regional lymph nodes in 16. Recurrences were squamous cell carcinomas in 42 and adenoid cys...
متن کاملIntensity-modulated radiation therapy for head and neck cancer.
Radiotherapy planning studies have confirmed dosimetric advantages of intensity-modulated radiation therapy over conventional and conformal radiation therapy. Utilization of intensity-modulated radiation therapy is ideal in head and neck cancer patients. Critical structures can be spared due to sharp dose gradients and limited organ motion with correct immobilization. Initial clinical results h...
