OBJECTIVES This study investigated late toxicity and infield progression-free survival in patients with locally recurrent rectal cancer (LRRC) who had previously received irradiation to the pelvis. METHODS Twenty-two patients were treated by reirradiation to the pelvis between January 2000 and August 2007. All patients received curative surgery with(More)
BACKGROUND The objective of this study was to determine whether cyclooxygenase-2 (COX-2) overexpression was an indicator of prognosis in patients with International Federation of Gynecology and Obstetrics (FIGO) Stage IIB uterine cervical carcinoma who underwent radiation and concurrent chemotherapy. METHODS Seventy-five patients with FIGO Stage IIB(More)
PURPOSE The purpose of this study was to compare the validity of staging systems, as well as to identify the staging system with the best prognostic value, in hepatocellular carcinoma (HCC) patients treated with radiotherapy. METHODS AND MATERIALS From 1992 to 2003, a total of 305 patients undergoing radiotherapy for HCC were evaluated retrospectively.(More)
PURPOSE To investigate the patterns of local failure and the risk factors predictive of local failure and to establish the dose-response relationships influencing the probability of local control in patients with Stage I and II angiocentric T-cell or natural killer (NK)/T-cell lymphoma who were treated with radiotherapy (RT) alone. METHODS AND MATERIALS(More)
PURPOSE In order to determine the effect of additional radiotherapy (RT) after an incomplete transcatheter arterial chemoembolization (TACE) in an unresectable hepatocellular carcinoma (HCC), the treatment results of patients receiving TACE plus RT were analyzed and compared with those treated with TACE alone. MATERIALS AND METHODS One hundred and five(More)
AIM To determine the national practice processes of care and outcomes of radiotherapy for hepatocellular carcinoma (HCC) in Korea. PATIENTS AND METHODS A national survey of 53 institutions nationwide was conducted by requesting data on their experience of radiotherapy for HCC. Among them, 10 institutions were selected for performing more detailed(More)
PURPOSE The purpose of this study was to investigate the role of postmastectomy radiation therapy (PMRT) after neoadjuvant chemotherapy (NAC) in clinical stage II-III breast cancer patients with pN0. METHODS AND MATERIALS We retrospectively identified 417 clinical stage II-III breast cancer patients who achieved an ypN0 at surgery after receiving NAC(More)
BACKGROUND The aim of this study was to assess the results of curative surgery with and without radiotherapy in patients with T1-2N0-1 oral tongue squamous cell carcinoma (OSCC) and to evaluate survival and prognostic factors. METHODS Retrospective analysis of 86 patients with T1-2N0-1 OSCC who received surgery between January 2000 and December 2006.(More)
PURPOSE The purpose of this study was to identify radiotherapeutic parameters for predicting the occurrence of liver complications induced by radiotherapy of a liver tumor. METHODS AND MATERIALS From 2001 to 2003, a total of 131 patients with hepatocellular carcinoma received three-dimensional conformal radiotherapy. The total dose was determined by the(More)
PURPOSE To elucidate the clinical behavior and treatment outcome of low-grade primary orbital lymphoma arising from mucosa-associated lymphoid tissue (MALT). METHODS AND MATERIALS Forty-eight patients with pathologically confirmed marginal zone B-cell lymphoma of MALT were treated with radiotherapy (RT). Thirty-eight patients (79.1%) received thorough(More)
