BACKGROUND AND PURPOSE To measure the distance between surgical clips and edge of CT-defined seroma in a coronal plane in women who have undergone wide local excision of breast cancer and to evaluate dosimetric coverage of CT-defined boost volumes by conventional clip-based electron fields. MATERIALS AND METHODS Planning CT images of 30 lumpectomy(More)
PURPOSE To assess the factors that predict local control and survival in patients with thymoma treated with adjuvant radiotherapy (RT) and suggest strategies for optimizing adjuvant RT. METHODS AND MATERIALS The study population comprised 47 patients with noninvasive thymoma and 128 patients with invasive thymoma. Treatment was surgery in 175 patients and(More)
BACKGROUND To investigate patterns of failure and survival rates of elective irradiation of upper neck in N0 nasopharyngeal carcinoma patients. METHODS From February 1996 to November 2002, 97 patients without cervical lymph node involvement were admitted for radiotherapy alone. Before treatment, each patient underwent enhanced CT of nasopharynx and neck.(More)
The purpose of this study was to evaluate the efficacy and toxicity of cisplatin plus gemcitabine chemotherapy and intensity-modulated radiation therapy (IMRT) for locoregionally advanced nasopharyngeal carcinoma (NPC). A total of 54 patients (stage IIB: 6, stage III: 24, stage IVA–B: 24) with locoregionally advanced NPC were treated with cisplatin 25 mg/m2(More)
PURPOSE To document the long-term efficacy of intraoperative electron radiotherapy (IOERT) followed by concurrent chemotherapy and external-beam radiotherapy (EBRT) in the management of locally advanced gastric cancer. MATERIALS AND METHODS A total of 97 consecutive patients with T3/4 or N+ gastric adenocarcinoma were enrolled. Fifty-one patients received(More)
OBJECTIVES To follow up the efficacy and incidence of radiation-induced complications of late course accelerated fractionation (LCAF) radiotherapy in early-stage nasopharyngeal carcinoma (NPC). MATERIALS AND METHODS From December 1995 to November 2002, 158 patients with stages I-II NPC were admitted for radiotherapy alone. For the first two-thirds of the(More)
OBJECTIVE Surgery is the mainstay treatment for transitional cell carcinoma (TCC) of the ureter; however, local recurrence remains a common cause of treatment failure for locally advanced disease after surgery, and the benefit of adjuvant radiotherapy has not been completely determined. The objective of this analysis was to evaluate the outcome of(More)
