Purpose To compare the effectiveness of mammography, breast ultrasound, and magnetic resonance imaging (MRI) for surveillance of women at increased familial risk for breast cancer (lifetime risk of 20% or more). Patients and Methods We conducted a surveillance cohort study of 529 asymptomatic women who, based on their family history and/or mutational analysis, were suspected or proven to carry a breast cancer susceptibility gene (BRCA). A total of 1,542 annual surveillance rounds were completed with a mean follow-up of 5.3 years. Diagnostic accuracies of the three imaging modalities used alone or in different combinations were compared. Results Forty-three breast cancers were identified in the total cohort (34 invasive, nine ductal carcinoma-in-situ). Overall sensitivity of diagnostic imaging was 93% (40 of 43 breast cancers); overall node-positive rate was 16%, and one interval cancer occurred (one of 43 cancers, or 2%). In the analysis by modality, sensitivity was low for mammography (33%) and ultrasound (40%) or the combination of both (49%). MRI offered a significantly higher sensitivity (91%). The sensitivity of mammography in the higher risk groups was 25%, compared with 100% for MRI. Specificity of MRI (97.2%) was equivalent to that of mammography (96.8%). Conclusion Mammography alone, and also mammography combined with breast ultrasound, seems insufficient for early diagnosis of breast cancer in women who are at increased familial risk with or without documented BRCA mutation. If MRI is used for surveillance, diagnosis of intraductal and invasive familial or hereditary cancer is achieved with a significantly higher sensitivity and at a more favorable stage.

Aim. To analyze sensitivity of magnetic resonance imaging (MRI) in the diagnosis of breast cancer when used after mammography and breast ultrasound.Methods. The study included 70 patients with nonpalpable breast lesions who had changes of breast tissue found at previous studies (mammography and breast ultrasound). MRI was performed with the use of Siemens Magnetom Avanto with magnetic field 1.5 Tl.Results. Most frequently nonpalpable lesions were diagnosed in 45 to 60-year old patients (60%), a little rarer - in 39 to 45-year old patients (22.9%), in patients at the age of 61 to 69 - in 10.0% (7 patients). 7.1% patients were over 70. All first detected nonpalpable lesions of breast were biopsied for morphological verification. With the combined use of mammography, sonography, MRI and stereotactic biopsy the diagnosis was made in 100% patients. MRI with contract enhancement showed no relation between sensitivity, specificity and reliability and density of breast tissues.Conclusions. MRI is considered a highly sensitive method of diagnosis and identification of changes found at mammography and breast ultrasound.

Aims and background Breast cancer is the most common cancer affecting women, and it is associated with or due to a genetic predisposition in 5%-10% of the cases. Owing to the higher risk of developing breast cancer and the early onset of the disease in women proved or suspected to be carriers of a breast cancer susceptibility gene, a dedicated screening should be offered as a less invasive approach with the otherwise suggested prophylactic mastectomy. This should be optimized in order to overcome the limitations of conventional breast imaging with the application of new technologies such as breast magnetic resonance imaging. Methods A diagnostic protocol for routine control in patients at high risk of developing breast cancer has been prepared. Within a 7-month period, 23 patients suspected or proved to carry a breast cancer susceptibility gene underwent breast magnetic resonance imaging. Results Four breast cancers were identified with breast magnetic resonance imaging. In these cases, mammography was negative because of the density of the parenchyma or for its fibroglandular pattern. Ultrasound was negative in 2 cases, not specific for malignancy in 1 case, and considered as only possibly malignant but with biopsy recommendation on the basis of magnetic resonance findings in the last one. Clinical analysis was positive for a mass in 2 cases. Conclusions The accuracy of breast magnetic resonance imaging is known to be higher than that of conventional imaging in the study of breast parenchyma. High spatial resolution, no breast density influence and multiplanarity can give more detailed information about the smaller lesions and the right extension of the disease. Preliminary studies where breast magnetic resonance imaging is performed in addition to mammography within this group of patients are encouraging. We also believe that the application of breast magnetic resonance imaging can be very useful in the detection of cancer as early as possible with the aim to obtain the highest chance of survival after treatment.

Background. Triple negative breast cancer has a poor prognosis. Therefore, it is vital to detect this subtype of breast cancer in its early stage. The imaging features of this clinically important subtype of breast cancer are not well known. There have been no published reports about radiological diagnostics of triple negative breast tumour in Lithuania. The purpose of this study was to review the imaging characteristics of triple receptor negative cancers in mammography, ultrasonography and magnetic resonance imaging (MRI). Materials and methods. The published data for the period 2006–2011 concerning the imaging of triple negative breast cancer were analyzed. There were ten retrospective, ten prospective studies and five reviews. Five studies were on mammography imaging, three on both mammography and ultrasonography imaging, and five studies dealt with MR imaging data. Two studies analysed all three diagnostic methods. Results. In mammography, triple negative breast (TRN) cancers often present as a mass and are most frequently round, oval or lobular in shape, less frequently being irregular. TRN tumours aren’t associated with calcifications. Moreover, architectural distortion is not a characteristic feature of triple negative breast cancer. In ultrasonography, TRN cancer appears as a parallel. TRN breast tumours mostly are irregular in shape and have a circumscribed margin. Attenuating posterior echoes and hypervascularity are not their characteristic features. In MR imaging, TRN breast cancer tends to have a lobulated, round or oval mass shape. Rim enhancement is identified in most of TRN tumours. Initially, rapid enhancement with a washout pattern (a sign of malignancy) does not usually apply to triple-negative breast cancers. Conclusions. TRN breast cancer is difficult to diagnose, because usually it has no specific imaging signs typical of breast cancer. In mammography, TRN cancers aren’t associated with microcalcifications. In ultrasonography, attenuating posterior echoes and hypervascularity are not characteristic features of TRN tumours. In MRI, initially rapid enhancement with a washout pattern does not usually apply to triple-negative breast cancers.
