PURPOSE To prospectively compare clinical breast examination (CBE), mammography, ultrasonography (US), and contrast material-enhanced magnetic resonance (MR) imaging for screening women at genetic-familial high risk for breast cancer and report interim results, with pathologic findings as standard. MATERIALS AND METHODS Institutional review board of each(More)
This report presents the preliminary results of the first phase (21 months) of a multi-centre, non-randomised, prospective study, aimed at evaluating the effectiveness of contrast-enhanced magnetic resonance imaging (MRI), X-ray mammography (XM) and ultrasound (US) in early diagnosis of breast cancer (BC) in subjects at high genetic risk. This Italian(More)
OBJECTIVES : To prospectively compare clinical breast examination, mammography, ultrasonography, and contrast-enhanced magnetic resonance imaging (MRI) in a multicenter surveillance of high-risk women. MATERIALS AND METHODS : We enrolled asymptomatic women aged ≥ 25: BRCA mutation carriers; first-degree relatives of BRCA mutation carriers, and women with(More)
State-of-the-art screening mammography allows the detection of nonpalpable breast lesions in approximately 30 % of patients. The presence of clustered microcalcifications without evidence of solid tumors usually requires further investigations, mainly biopsy. A 1.5-T magnet with a single breast coil was used to evaluate 32 patients with indeterminate(More)
AIMS To evaluate the reliability of magnetic resonance imaging (MRI) performed with three-dimensional (3D) sequences in mammographically detected breast microcalcifications. METHODS During an 8-month period, a group of 28 patients with mammographically detected microcalcifications suspicious for malignancy underwent MRI. Their ages ranged from 33 to 65(More)
Patients with diffuse pontine gliomas have a median survival of less than one year and represent a challenge for pediatric oncologists, prompting them to attempt experimental therapies. From 1987 to 2005, 62 children with diffuse pontine glioma, not amenable to curative surgery, were treated according to four successive pilot protocols: (1) concomitant(More)
BACKGROUND Although axillary surgery is still considered to be a fundamental part of the management of early breast cancer, it may no longer be necessary either as treatment or as a guide to adjuvant treatment. The authors conducted a single-center randomized trial (INT09/98) to determine the impact of avoiding axillary surgery in patients with T1N0 breast(More)
RATIONALE AND OBJECTIVES To review magnetic resonance imaging (MRI) findings in lobular breast carcinoma, the in situ or infiltrating subtype, with special attention to the dynamic curves with the aim to evaluate possible differences with ductal carcinoma. METHODS In 2 years, 27 patients with lobular and one with tubular carcinoma underwent MRI at the(More)
We evaluated whether 18F-3′-deoxy-3′-fluorothymidine positron emission tomography (FLT PET) can predict the final postoperative histopathological response in primary breast cancer after the first cycle of neoadjuvant chemotherapy (NCT). In this prospective cohort study of 15 patients with locally advanced operable breast cancer, FLT PET evaluations were(More)
AIMS AND BACKGROUND We evaluated the response of locally advanced breast cancer to induction chemotherapy using MRI techniques. The size and vitality of any residual pathologic tissue was quantified by means of morphologic and dynamic analysis. A curve derived from the dynamic parameters shows the uptake intensity with respect to the time elapsed since(More)
