Long-term results (10 years) of intensive breast conserving therapy including a high-dose and large-volume interstitial brachytherapy boost (LDR/HDR) for T1/T2 breast cancer.

Background And Purpose: During the past 15 years many retrospective studies and prospective randomized trials have been published supporting the use of breast conserving treatment (BCT) including surgery and radiotherapy. However, there are still many controversies on the necessary amount of resection, the width of the resection margins and the optimal radiation technique, dose and volume, in particular of the boost. In this retrospective study a large cohort of 410 women with early breast cancer treated with BCT including an interstitial brachytherapy (BT) boost is evaluated after a long follow-up period.

Attitude towards prophylactic surgery and effects of genetic counselling in families with BRCA mutations. Austrian Hereditary Breast and Ovarian Cancer Group.

The intent of this study was to evaluate the effect that an awareness of being a BRCA1 or BRCA2 mutation carrier has on the attitude towards prophylactic surgery and on developing depression symptoms. Thirty-five families were selected on the basis of previously detected BRCA1 or 2 mutations and 90 family members were given the appropriate questionnaires. Prophylactic mastectomy (PM) was considered by 21% of the Austrian mutation carriers (29% affected and 8% non-affected carriers).

Denaturing high-performance liquid chromatography detects reliably BRCA1 and BRCA2 mutations.

Denaturing high-performance liquid chromatography (DHPLC) is a recently developed method of comparative sequencing based upon heteroduplex detection. To assess the reliability of this method, 180 different mutations (54 deletions, 12 insertions, and 117 single base substitutions) in BRCA1 and BRCA2 were tested. Second, 25 index individuals with complete DHPLC analysis of BRCA1 were reanalyzed by dye-terminator sequencing.

Global sequence diversity of BRCA2: analysis of 71 breast cancer families and 95 control individuals of worldwide populations.

The aim of this study was to evaluate the prevalence of simple sequence variation in the BRCA2 gene. To this end, 71 breast and breast-ovarian cancer (HBC/HBOC) families along with 95 control individuals from a wide range of ethnicities were analyzed by means of denaturing high-performance liquid chromatography (DHPLC) and direct sequence analysis. In the coding (10 257 bp) and non-coding (2799 bp) sequences of BRCA2, 82 sequence variants were identified.

Subjective perception of seizure precipitants: results of a questionnaire study.

We evaluated self-perception of seizure precipitants in 149 adult subjects with epilepsy: 71% of the subjects reported at least one factor that, according to the perception, increased the risk of suffering from a seizure. The subjects most often reported psychological stress, change of weather and sleep deprivation. Among the disease-related factors, seizure frequency and the state of consciousness at the onset of the seizures influenced perception of precipitants.
