OBJECTIVE The purpose of this study is to elucidate the usefulness of magnetic resonance imaging (MRI) and positron emission tomography (PET) for the detection of parametrial involvement and lymph node metastasis in patients with cervical cancer. METHODS Thirty-six patients with cervical cancer were retrospectively enrolled. MRI and PET scans were(More)
Although cisplatin-based chemotherapy is the standard of care for advanced transitional cell carcinoma, tolerability is a challenging issue in unfit patients. This study was conducted to evaluate the efficacy, toxicity, and tolerability of the combination of gemcitabine and carboplatin in unfit patients with advanced transitional cell carcinoma. Thirty-one(More)
We report the results of radiotherapy for abdominal lymph node metastasis from hepatocellular carcinoma (HCC). From 1998 to 2004, 45 cases were treated with radiotherapy (RT), with a dose between 30 and 55 Gy. The radiation response, overall survival, prognostic factors, and complications were evaluated. Thirty-nine cases were able to be evaluated for(More)
BACKGROUND To determine the optimal whole breast irradiation technique in patients with small-sized breasts, tangential and field-in-field IMRT (FIF) techniques were compared. METHODS Sixteen patients with ≤3 cm breast height and ≤350 cc volume were included. Seven patients had 4D CTs performed. The planning target volumes (PTV), editing 5 and 2 mm from(More)
PURPOSE To evaluate the response to local radiotherapy (RT) for unresectable hepatocellular carcinoma (HCC) and to analyze the dose-response relationship and the treatment-related morbidities. METHODS AND MATERIALS Between 1998 and 2002, 59 patients who were treated with localized RT were evaluated. RT was delivered with a curative intent, and the(More)
BACKGROUND The purpose of this study was to analyze the prognostic factors affecting local control and survival rates for patients with early breast cancer who received breast conserving treatment (BCT) and to find out the optimal treatment according to their risk factors. METHODS From October 1994 to December 2001, 605 patients with 611 stage I and II(More)
OBJECTIVE To evaluate the treatment outcome of three-dimensional conformal radiotherapy in hepatocellular carcinoma patients with portal vein thrombosis, concerning survival and treatment response of thrombosis. METHODS Forty-five patients with hepatocellular carcinoma who had portal vein thrombosis treated from March 2005 to March 2011 were the subjects(More)
AIMS AND BACKGROUND To determine whether the residual tumor volume measured using the Eclipse treatment planning system correlates with pathologic tumor regression grade after preoperative chemoradiotherpy for rectal cancer. MATERIALS AND METHODS The study included 30 patients with rectal cancer who had undergone preoperative chemoradiotherpy followed by(More)
To address the challenges of the parameterization of ocean color inversion algorithms in optically complex waters, we present an adaptive implementation of the linear matrix inversion method (LMI) [J. Geophys. Res.101, 16631 (1996)], which iterates over a limited number of model parameter sets to account for naturally occurring spatial or temporal(More)
PURPOSE To evaluate long-term local control rate and toxicity in patients treated with external beam radiotherapy (EBRT) for pituitary adenomas. MATERIALS AND METHODS We retrospectively reviewed the medical records of 60 patients treated with EBRT for pituitary adenoma at Korea University Medical Center from 1996 and 2006. Thirty-five patients had hormone(More)
