PURPOSE Radiation therapy (RT) restricted to the tumor bed, by means of an interstitial implant, and lasting 4 to 5 days after lumpectomy was prospectively evaluated in early-stage breast cancer patients treated with breast-conserving therapy (BCT). The goals of the study were to determine whether treatment time can be reduced and whether elective treatment(More)
BACKGROUND Several phase III trials have demonstrated equivalent long-term survival between breast conserving surgery plus radiation therapy and mastectomy in patients with early-stage breast cancer but have not provided information on the optimal volume of breast tissue requiring post-lumpectomy radiation therapy. Therefore, we examined the 5-year results(More)
BACKGROUND The link of the apolipoprotein (APOE) -epsilon4 allele to Alzheimer disease (AD) has led to studies investigating the role of apoE polymorphisms in Parkinson disease (PD). The authors hypothesized that any association between PD and APOE alleles and genotypes would be too small to be detected or precisely estimated by an individual(More)
The apolipoprotein E (APOE) epsilon2 allele has been associated with both Parkinson's disease (PD) and lower low-density lipoprotein cholesterol (LDL-C). We tested the hypothesis that lower LDL-C may be associated with PD. This case-control study used fasting lipid profiles obtained from 124 PD cases and 112 controls. The PD cases were recruited from(More)
PURPOSE We present the preliminary findings of our in-house protocol treating the tumor bed alone after lumpectomy with low-dose-rate (LDR) interstitial brachytherapy in selected patients with early-stage breast cancer treated with breast-conserving therapy (BCT). METHODS AND MATERIALS Since March 1, 1993, 60 women with early-stage breast cancer were(More)
PURPOSE We reviewed our institution's experience treating patients with ductal carcinoma-in-situ (DCIS) with breast-conserving therapy (BCT) to determine the impact of patient age on outcome. PATIENTS AND METHODS From 1980 to 1993, 146 patients were treated with BCT for DCIS. All patients underwent excisional biopsy, and 64% underwent re-excision. All(More)
AIM Thalassaemia is a good candidate disease for control by preventive genetic programmes in developing countries. Accurate population frequency data are needed for planning the control of thalassaemia in the high risk Guangdong Province of southern China. METHODS In total, 13397 consecutive samples from five geographical areas of Guangdong Province were(More)
PURPOSE We reviewed our institution's experience treating patients with ductal carcinoma in situ (DCIS) of the breast to determine risk factors for ipsilateral breast tumor recurrence (IBTR) and cause-specific survival (CSS) after breast-conserving therapy (BCT) or mastectomy. MATERIALS AND METHODS Between 1981 and 1999, 410 cases of DCIS (405 patients)(More)
PURPOSE A new device has been developed with the goal of making breast-conserving therapy more widely available, by making breast brachytherapy as monotherapy simpler and more accurate. This is the first published report on the dosimetric characteristics of this device. MATERIALS AND METHODS The experience of a single institution participating in a(More)
BACKGROUNDS AND OBJECTIVES We present the interim findings of our in-house protocol treating the tumor bed alone after lumpectomy with low-dose-rate (LDR) interstitial brachytherapy in selected patients with early-stage breast cancer treated with breast conserving therapy (BCT). METHODS From 1 March 1993 through 1 January 1995, 50 women with early-stage(More)
