To enhance the accuracy of radioactive seed implants in the head and neck, a digital model individual template, containing information simultaneously on needle pathway and facial features, was designed to guide implantation with CT imaging. Thirty-one patients with recurrent and local advanced malignant tumors of head and neck after prior surgery and(More)
Oral squamous cell carcinoma (OSCC) is predominantly a disease of middle-aged men with long-term exposure to tobacco and alcohol. An increasing trend has been reported at a younger age worldwide. Clinical records of 100 patients under the age of 45 years treated specifically for oral cavity SCC in our hospital during a 10-year period were retrospectively(More)
OBJECTIVE To detect the efficacy of (125)I radioactive seeds implanting treating malignant salivary gland tumors. METHODS Forty-three patients with malignant salivary gland tumors of head neck were treated with (125)I radioactivity seeds interstitial brachytherapy at Peking University Stomatologic Hospital between 2001 and 2008. These patients were(More)
OBJECTIVE To evaluate the feasibility of cone beam computed tomography (CBCT) for the evaluation of trabecular bone structure in mandibular condyle and to investigate the distribution of the trabecular bone structure within mandibular condyle. METHODS Eighty condyles from 40 healthy young volunteers (aged 20-32) were scanned by CBCT. A coronoid image was(More)
This retrospective study was undertaken to analyze data from patients receiving iodine-125 ([125I]) seed brachytherapy postoperatively for the treatment of acinic cell carcinoma (ACC) of the parotid gland along with the following risk factors: residual tumor, recurrent tumor, facial nerve invasion, positive resection margins, advanced tumor stage, or tumor(More)
OBJECTIVE To investigate clinical features of distant metastases (DM) and analyze clinicopathologic risk factors associated with DM from salivary gland carcinomas after being treated by surgery combined with 125I internal brachytherapy. METHODS Between October 2001 and March 2010, 197 patients with salivary gland carcinoma were treated by surgery combined(More)
Salivary adenoid cystic carcinoma (SACC), which is one of the most common malignant tumors of the salivary glands, is associated with a poor long-term outcome. There are currently few therapeutic options for patients with SACC. Recent studies have shown the potential of the application of ultraviolet-C (UV-C) irradiation for the treatment of human cancer.(More)
To transfer the preplan for the head and neck brachytherapy to the clinical implantation procedure, a preplan-based 3D-printed individual template for needle insertion guidance had previously been designed and used. The accuracy of needle insertion using this kind template was assessed in vivo In the study, 25 patients with head and neck tumors were(More)
We studied the incidence and dose–response relationship of radioepidermitis in parotid gland carcinoma patients treated with [125I] seed brachytherapy in the hopes of designing an optimized pre-implant treatment plan that would reduce the incidence and severity of radioepidermitis in patients receiving this therapy. Between January 2007 and May 2010, 100(More)
It was well recognized that Pb had a poisoning effect on a SCR catalyst. In this study, the deactivation mechanism of Pb on the Ce/TiO2 catalyst was investigated based on the characterization results of TPD and in situ DRIFT studies. It was found that the addition of Pb on the Ce/TiO2 catalyst not only inhibited the adsorption and activation of NH3 species,(More)
