Twelve patients with hepatocellular carcinoma and chronic hepatitis developed radiation-induced liver disease (RILD) after three-dimensional conformal radiotherapy. Six patients died of RILD and six recovered. Mean prescribed dose was 50.6+/-4.3Gy, in a daily fraction of 1.8-2.0Gy. Commonly used dosimetric parameters, such as fraction volume of normal liver(More)
PURPOSE To define a subgroup of patients at high risk of locoregional recurrence (LRR) who might be benefit from postmastectomy radiotherapy in invasive breast cancer and tumor size <5 cm with one to three involved axillary lymph nodes (T1-2 N1). METHODS AND MATERIALS Between April 1991 and December 2005, 544 patients with T1-2 N1 invasive breast cancer(More)
PURPOSE To evaluate the treatment outcome, patterns of failure, and prognostic factors for patients with unresectable hepatocellular carcinoma (HCC) treated with local radiotherapy alone or as an adjunct to transcatheter arterial chemoembolization (TACE). METHODS AND MATERIALS From March 1994 to December 1997, 25 patients with unresectable HCC underwent(More)
PURPOSE To analyze the incidence and risk factors for locoregional recurrence (LRR) in patients with breast cancer who had T1 or T2 primary tumor and 1-3 histologically involved axillary lymph nodes treated with modified radical mastectomy without adjuvant radiotherapy (RT). MATERIALS AND METHODS Between April 1991 and December 1998, 125 patients with(More)
The purpose of our study was to evaluate the outcome, patterns of failure, and toxicity for patients with unresectable hepatocellular carcinoma (HCC) treated with radiotherapy, transcatheter arterial chemoembolization (TACE), or combined TACE and radiotherapy. Forty-two patients with unresectable HCC were treated with combined radiotherapy and TACE (TACE+RT(More)
BACKGROUND The purpose of this study was to determine the potential role of three-dimensional (3-D) conformal radiotherapy (RT) in treatment of unresectable hepatocellular carcinoma (HCC). METHODS Thirteen patients were included in this study, which was conducted between 1993 and 1996. Nine patients (group A) were treated with 3-D conformal RT alone(More)
PURPOSE To retrospectively assess the risk of locoregional recurrence (LRR) and analyze the prognostic factors of this pattern of failure in patients with breast cancer and one to three positive axillary lymph nodes treated with modified radical mastectomy (MRM) without adjuvant radiotherapy. METHODS From April 1991 through December 1997, 649 patients(More)
