BACKGROUND Brain metastases from esophageal carcinoma are extremely rare, and information regarding the natural history, results of treatment, and possible prognostic factors in these patients is limited. METHODS The records of 36 patients with brain metastases from esophageal carcinoma who were treated between 1986 and 2000 were reviewed. For brain(More)
Brain metastases from gynecological cancers were retrospectively investigated in 18 patients who were treated between 1985 and 2006. Six patients received surgical resection followed by radiotherapy, and 12 patients received only radiotherapy. The median survival for all patients was 4.1 months (range 0.7-48.2 months), and the actuarial survival rates were(More)
BACKGROUND Thymic carcinomas are rare neoplasms, and information regarding the results of treatment and possible prognostic factors in patients with these tumors is limited. METHODS The records of 40 patients with histologically confirmed thymic carcinoma who were treated between 1984 and 1998 were reviewed. Twenty-seven patients were treated with(More)
PURPOSE Optimal management of radiotherapy (RT) for intracranial germinoma remains controversial. This study was conducted to evaluate the long-term results of RT in patients with these tumors. METHODS AND MATERIALS The study group consisted of 126 patients with intracranial germinoma (50 patients with pathologically verified germinoma and 76 clinically(More)
PURPOSE To analyze retrospectively the risk factors of spinal recurrence in patients with intracranial germinoma and clinical outcomes of patients who developed spinal recurrence. METHODS AND MATERIALS Between 1980 and 2007, 165 patients with no evidence of spinal metastases at diagnosis were treated with cranial radiotherapy without spinal irradiation.(More)
BACKGROUND Optimal management of postoperative radiotherapy for patients with completely resected thymoma remains controversial. This study was conducted to assess the efficacy of postoperative mediastinal irradiation in patients with completely resected thymoma. METHODS The records of 103 patients with completely resected thymoma who received(More)
PURPOSE To identify the characteristics, risk factors, and clinical outcomes of radiation enterocolitis requiring surgery in patients with gynecologic malignancies. METHODS AND MATERIALS The records of 1,349 patients treated with pelvic radiotherapy were retrospectively reviewed. The majority of the patients (88%) were treated with 50 Gy or 50.4 Gy pelvic(More)
OBJECTIVE To assess the feasibility and outcome of concurrent chemoradiotherapy (CT-RT) with large regional field and high-dose external beam boost irradiation in thoracic esophageal cancer. METHODS Patients with clinical stage T1 (submucosal)-4N0-1M0 (UICC 1997) squamous cell carcinoma of the thoracic esophagus were eligible. Radiotherapy consisted of(More)
OBJECTIVE We retrospectively reviewed our experience with concurrent chemoradiotherapy (CCRT) using high-dose-rate intracavitary brachytherapy (HDR-ICBT) to assess its feasibility and efficacy in the treatment of patients with uterine cervical cancer. METHODS Forty patients with uterine cervical squamous cell carcinoma treated with CCRT using HDR-ICBT(More)
PURPOSE To determine an appropriate dose and fractionation schedule for a combination of external beam radiotherapy (EBRT) and high-dose-rate intracavitary brachytherapy (HDR-ICBT) for uterine cervical cancer. METHODS Eighty-eight patients with uterine cervical squamous cell carcinoma treated with EBRT and HDR-ICBT were analyzed. Twenty-five patients were(More)
