It has been reported that pure ductal carcinoma in situ of the breast has morphologic differences from the in situ component of the invasive ductal carcinoma, as well estrogen and progesterone receptors expression according to their cytokeratin expression. However, there is no data comparing other tumor markers without using the cytokeratin expression. The objective of this study is to compare the expression of estrogen receptor (ER) and progesterone receptor (PR), HER-2/neu, p53, and Ki67 between pure ductal in situ carcinoma (pDCIS) and the in situ component of the invasive ductal carcinoma (DCIS + IDC) of the breast, and the in situ component to the invasive component of the same tumor (DCIS + IDC). The immunohistochemistry expression of the tumor markers was performed in 45 cases of pDCIS and DCIS + IDC, yielding a total of 90 cases. Statistical analysis was carried out using Fisher exact test, having a P < 0.05, and Kappa index (kappa) to assess intratumoral concordance. In DCIS + IDC, the in situ and invasive components did not show a significant difference and Kappa index (kappa) was high (0.7-1) for positive and negative expression. ER and PR were significantly different between the pDCIS and DCIS + IDC (ER: 86.7 vs. 66.7% P = 0.04; PR: 80% vs. 55.6% P = 0.02). These findings suggest that in situ component of DCIS + IDC and pDCIS are distinct conditions.

Purpose: To evaluate the use of contrast enhanced mammography (CEM) in suspicious microcalcifications and to discuss strategies to cope with its diagnostic limitations.
Methods: We retrospectively evaluated patients with suspicious calcifications who underwent CEM at our institution. We collected and analyzed morphological findings, enhancement patterns and pathological findings of suspicious microcalcifications on CEM.

An estimated 55,720 new cases of ductal carcinoma in situ (DCIS) will be diagnosed in 2023 in the USA alone because of the increased use of screening mammography. The treatment goal in DCIS is early detection and treatment with the hope of preventing progression into invasive disease. Previous studies show progression into invasive cancer as well as reduction in mortality from treatment is not as high as previously thought.

Invasive ductal carcinoma (IDC) is the most common type of breast cancer, primarily affecting women in the United States and across the world. This review summarizes key concepts related to IDC causes, treatment approaches, and the identification of biological markers for specific prognoses. Furthermore, we reviewed many studies, including those involving patients with IDC and ductal carcinoma in situ (DCIS) that progressed to IDC.

Background: Contrast-enhanced ultrasound (CEUS) shows potential for the differential diagnosis of breast lesions in general, but its effectiveness remains unclear for the differential diagnosis of lesions highly suspicious for breast cancers.
Objective: This study aimed to evaluate the diagnostic value of CEUS in differentiating pathological subtypes of suspicious breast lesions defined as category 4 of US-BI-RADS.
Methods: The dataset of 150 breast lesions was prospectively collected from 150 patients who underwent routine ultrasound and CEUS examination and were highly suspected of having breast cancers.

Introduction: Ductal carcinoma (DCIS) accounts for 25% of newly diagnosed breast cancer cases with only 14%-53% developing into invasive ductal carcinoma (IDC), but currently overtreated due to inadequate accuracy of mammography. Subtypes of calcification, discernible from histology, has been suggested to have prognostic value in DCIS, while the lipid composition of saturated and unsaturated fatty acids may be altered in synthesis with potential sensitivity to the difference between DCIS and IDC. We therefore set out to examine calcification using ultra short echo time (UTE) MRI and lipid composition using chemical shift-encoded imaging (CSEI), as markers for histological calcification classification, in the initial step towards application.
