Results of carbon ion radiotherapy for head and neck cancer.
PURPOSE To evaluate the efficacy of carbon ion radiotherapy for head-and-neck cancer in a phase II clinical trial. MATERIALS AND METHODS Between April 1997 and February 2006, 236 patients with locally advanced, histologically proven, and new or recurrent cancer of the head and neck were treated with carbon ions. The treatment dose was 64.0 GyE/16 fractions/4 weeks (or 57.6 GyE/16 fractions/4 ...
متن کاملMolecular imaging in radiotherapy planning for head and neck tumors.
Molecular imaging uses noninvasive techniques to visualize various biologic pathways and physiologic characteristics of tumors and normal tissues. In relation to radiation therapy, PET with the tracer (18)F-FDG offers a unique opportunity to refine the target volume delineation in patients with squamous cell carcinoma of the head and neck, in turn affecting dose distribution and, it is hoped, p...
متن کاملOtotoxicity after radiotherapy for head and neck tumors.
PURPOSE To investigate the incidence of radiation-induced ototoxicity according to the total dose delivered to specific parts of the auditory system, fractionation, and chemotherapy. METHODS AND MATERIALS Records of 325 patients treated for primary extracranial head and neck tumors with curative intent who received radiotherapy between 1964 and 2000 (median follow-up, 5.4 years) were retrospe...
متن کاملCarbon-ion Radiotherapy for Non-squamous Cell Head and Neck Malignancies
The head and neck region consists of subsites, including the oral cavity, pharynx, larynx, nasal sinuses, salivary glands, and orbits, and contains important organs performing functions that are directly related to the Quality of Life (QOL), such as chewing, swallowing, and phonation. It has been reported that 32% of head and neck cancers occur in the oral cavity, 24% in the larynx, 35% in the ...
متن کاملRadiation-induced Parotid Gland Atrophy in Patients with Head and Neck Cancer After Carbon-ion Radiotherapy.
BACKGROUND/AIM This study aimed to clarify the relationship between dosimetric factors and parotid gland (PG) atrophy after carbon ion radiotherapy (C-ion RT). PATIENTS AND METHODS Fifty-four patients with head and neck tumours were enrolled and 93 irradiated PGs were analyzed. Thirty and 24 patients were treated with total doses [relative biological effectiveness (RBE)] of 57.6 Gy and 64.0 G...
