PURPOSE To evaluate the comparative accuracy of magnetic resonance (MR) imaging relative to mammography and ultrasonography (US) for assessing the extent of breast tumors. MATERIALS AND METHODS Histologic results and preoperative imaging findings (mammography, US, MR imaging) were analyzed regarding tumor size and multifocality of 61 tumors in 60 women(More)
Breast cancer multifocality was studied in mastectomy specimens by correlated specimen radiography and histologic techniques. The patients chosen for study were comparable to those eligible for breast-conserving surgical therapy. Two study groups, one with 282 invasive cancers (T1-2) and the other with 32 intraductal cancers, were selected from a group of(More)
Based on an extensive cost-effectiveness analysis, the Dutch nation-wide breast cancer screening programme started in 1990, providing a biennial screen examination to women aged 50 to 69 years. The programme is monitored by the National Evaluation Team, which annually collects tabulated regional evaluation data to determine performance indicators. This(More)
Mammographic screening for women aged 50-70 is effective in reducing breast cancer mortality, but the impact on quality of life and the attainable mortality reduction remain to be discussed. The consequences of expanding screening programmes to include women in other age groups are uncertain. We have predicted the effects and costs for 5 popular screening(More)
BACKGROUND The recall rate (i.e., the rate at which mammographically screened women are recalled for additional assessment) in the Dutch breast screening program (0.89% in 2000 for subsequent examinations) is the lowest worldwide, with possible consequences including higher rates of late-detected (i.e., "missed") interval and screen-detected cancers. To(More)
To find out whether ultrasound-guided fine-needle aspiration (FNA) and ultrasound and stereotactic-guided large core needle biopsy (LCNB) are reliable alternatives to needle-localised open breast biopsy (NLBB) in daily practice, we performed a retrospective study and evaluated the validity of these methods. In all, 718 women with 749 nonpalpable breast(More)
To assess the potential of breast-conserving treatment for ductal carcinoma in situ (DCIS), 82 mastectomy specimens were studied by Egan's serial subgross method. 42 (51%) of the tumours were larger than 50 mm and only 12 (15%) were smaller than 20 mm; the size distribution was not affected by the mode of detection (mammography 52 cases, clinical(More)
BACKGROUND Currently, there have been no reports of clear-cut beneficial effects of regular screening with mammography at a mean screening interval of 2 years in women younger than 50 years of age. It may be that, because of a higher growth rate of breast cancer, more frequent screening is necessary if any effect is to be observed in this age group.(More)
PURPOSE To evaluate the impact of high-energy transurethral microwave thermotherapy (TUMT) and transurethral prostatic resection (TURP) on quality of life (QoL) in patients with benign prostatic hyperplasia (BPH). MATERIALS AND METHODS A total of 147 patients with BPH were randomized to receive either high-energy TUMT treatment (Prostasoft 2.5) or a TURP(More)
Since January 1975 a population-based screening programme for the early detection of breast cancer has been carried out in the city of Nijmegen. During five interscreening periods of 2 years each a total of 158 so-called interval cancers were diagnosed. Careful revision of all screening and diagnostic mammograms was executed. Of all interval cancers 26%(More)
