BACKGROUND A preliminary assessment was conducted of the feasibility, efficacy, and morbidity of 125I seed implantation for recurrent head and neck carcinoma after surgery and external beam radiotherapy. METHODS Nineteen patients with recurrent head and neck carcinomas underwent 125I seed implantation under ultrasound or computed tomography guidance. The(More)
BACKGROUND To assess the feasibility and efficacy of using 125I seed implantation under intraoperative ultrasound guidance for unresectable pancreatic carcinoma. METHODS Fourteen patients with pancreatic carcinoma that underwent laparotomy and considered unresectable were included in this study. Nine patients were pathologically diagnosed with Stage II(More)
Background: To assess the efficacy of intraoperative ultrasound-guided implantation of I seeds for the treatment of unresectable pancreatic carcinoma, and analyze the associated prognostic factors. Methods: Twenty-eight patients with pancreatic carcinoma who underwent laparotomy and were considered to have unresectable tumors were included in this study.(More)
The purpose of this study was to evaluate the safety and efficacy of percutaneous iodine-125 ((125)I) seed implantation using computed tomography (CT) or ultrasound guidance in the treatment of recurrent soft tissue malignancies after surgery and radiotherapy. From February 2002 to September 2009, 18 patients with recurrent soft tissue sarcomas were treated(More)

BACKGROUND The management of pediatric recurrent or metastatic soft tissue sarcoma after multimodal treatment remains challenging. We investigated the feasibility, efficacy, and morbidity of permanent interstitial (125)I seed implantation under image guidance as a salvage treatment for pediatric patients with recurrent or metastatic soft tissue sarcoma.

This study aimed to analysis outcome and prognosis of interstitial 125I seed implantation in patients with cervical lymph node recurrence after multimodal treatment of thoracic esophageal squamous cell carcinoma (ESCC). We conducted a retrospective review of 19 patients with 32 cervical lymph nodes recurrences after multimodal treatment (lymphadenectomy,(More)
BACKGROUND To assess the efficacy of intraoperative ultrasound-guided implantation of 125I seeds for the treatment of unresectable pancreatic carcinoma, and analyze the associated prognostic factors. METHODS Twenty-eight patients with pancreatic carcinoma who underwent laparotomy and were considered to have unresectable tumors were included in this study.(More)
Twenty-nine (29) patients with recurrent head and neck carcinomas underwent (125)I seed permanent implantation under ultrasonography guidance and the feasibility and efficacy of (125)I seed implantation were assessed. The postplan evaluation showed that the actuarial D90 of (125)I seeds ranged from 90 to 160 Gy (median, 130 Gy). The activity of each (125)I(More)
PURPOSE To evaluate color-Doppler features predictive of focal Hashimoto's thyroiditis. MATERIALS AND METHODS A total of 521 patients with 561 thyroid nodules that underwent surgeries or gun biopsies were included in this study. These nodules were divided into three groups: focal Hashimoto's thyroiditis (104 nodules in 101 patients), benignity other than(More)
