Accuracy of Tumor Size Measurements Performed by Magnetic Resonance, Ultrasound and Mammography, and Their Correlation With Pathological Size in Primary Breast Cancer

ConclusionsMRI is the best predictor of tumor size in breast cancer. Histologic type and tumor size are key parameters when estimating tumor size and should be taken into account when planning surgery. Patient age does not interfere with the interpretation of imaging tests.ResumenIntroducciónEl objetivo de este estudio fue evaluar qué prueba de imagen de las empleadas para medir el tamaño del cáncer de mama primario preoperatorio (mamografía, ecografía o resonancia magnética (RM)) se correlacionó mejor con el tamaño del tumor en la pieza quirúrgica postoperatoria.MétodosAnálisis retrospectivo de mujeres con diagnóstico de cáncer de mama y con indicación de tratamiento quirúrgico primario operadas desde Enero de 2014 a Diciembre de 2016. Se recogieron variables sociodemográficas, vinculadas a técnicas de imagen e histológicas. Los resultados se presentaron según edad, tamaño tumoral y tipo histológico.ResultadosSe estudiaron 224 mujeres. Al comparar el tamaño mamográfico y de la RM con el histológico final no se encontraron diferencias significativas, tanto de forma global como teniendo en cuenta el grupo histológico o la edad, sin embargo, ambas infraestimaron significativamente los tumores grandes y sobrestimaron significativamente los pequeños. La ecografía infraestimó signi...

Conclusion: The texture analysis for breast DCE-MRI proposed in this study demonstrated potential utility in HER2 2+ status discrimination. Background Human epidermal growth factor receptor 2 (HER2) is an orphan tyrosine kinase receptor. It is reported that HER2 is overexpressed in 15–20% of breast cancers. Overexpression of HER2 in breast cancer correlates with shortened disease-free survival. Compared with HER2-negative patients, patients with HER2-positive breast cancers have a poor prognosis, a high probability of lymph node metastasis and a high risk of recurrence (1–3). However, previous studies h...

Conclusion: For lesions initially described as BI-RADS 3 and 4a with a histological diagnosis of fibroadenoma after biopsy, short-term follow-up can be avoided.Breast Care 2017;12:238-242

Abstract Women who underwent chest radiation therapy (CRT) during pediatric/young-adult age (typically, lymphoma survivors) have an increased breast cancer risk, in particular for high doses. The cumulative incidence from 40 to 45 years of age is 13–20 %, similar to that of BRCA mutation carriers for whom contrast-enhanced magnetic resonance imaging (MRI) is recommended. However, in women who underwent CRT, MRI sensitivity is lower (63–80 %) and that of mammography higher (67–70 %) than those observed in women with hereditary predisposition, due to a higher incidence of ductal...

Conclusion Among imaging modalities, breast MRI can potentially distinguish between ypT0 and ypTis after NCT, especially in patients with triple-negative breast cancer. This information can help clinicians evaluate tumor response to NCT and plan surgery for breast cancer patients of all subtypes except for those with HER2-enriched tumors after NCT.

This article presents a retrospective review of patients with BND and negative conventional imaging, comparing outcome of patients who went directly to CDE without MRI to those patients who underwent preoperative MRI. Of 115 patients who underwent mammography and US alone prior to CDE, eight cancers were detected (seven ductal carcinoma in situ [DCIS] and 1 IDC, 7 mm [T1b]; incidence: 7%). Of 85 patients who underwent conventional imaging followed by MRI prior to surgery, eight cancers were detected (all DCIS; incidence: 9.4%), seven of which were identified by MRI. The one false‐negative MRI had subtle findings which, i...

Abstract: Sclerosing adenosis (SA) is a less common histopathological lesion of the breast that can coexist with proliferative lesions as well as malignancies. We aimed to analyze the clinicopathological characteristics of SA and to investigate the radiological features of SA. Patients who underwent breast surgery at our institute from 2007 to 2013 were retrospectively reviewed. A total of 815 breasts (722 patients) were included in the final analysis. Synchronous bilateral SA was defined as the detection of another SA arising in the contralateral breast within 1 month after surgery for the initial breast lesion. Baseline ...

Abstract Breast magnetic resonance imaging (MRI) has demonstrated increased sensitivity over conventional imaging in identifying and characterizing in situ and invasive, multifocal, and multicentric disease. A histologic diagnosis is required for any enhancing lesion displaying suspicious features, especially in the presence of lower and often variable reported specificity values. Breast MRI findings occult on mammography and ultrasound should undergo an MR‐guided biopsy. We retrospectively evaluate our 8 years’ experience with this procedure. Our study included 259 lesions in 255 consecutive patients referred for ...

Conclusion: This case suggests that the diagnosis of masses of the breast during pregnancy and lactation can be quite difficult. Diagnosis should be confirmed by an excision biopsy and by histological examination through an experienced pathologist. As a significant proportion of papillomas contain malignant regions, an argument exists for the complete excision of all papillary tumours.Breast Care

Purpose To evaluate the breast cancer screening efficacy of mammography, ultrasound, and magnetic resonance imaging (MRI) in a high-risk population and in various population subgroups. Patients and Methods In a single-center, prospective, nonrandomized comparison study, BRCA mutation carriers and women with a high familial risk (> 20% lifetime risk) for breast cancer were offered screening with mammography, ultrasound, and MRI every 12 months. Diagnostic performance was compared between individual modalities and their combinations. Further comparisons were based on subpopulations dichotomized by screening rounds, mutat...
