Objective: The objective of our study was to identify characteristic features of invasive lobular carcinoma on mammography and ultrasound examinations.
Materials And Methods: This is a retrospective multicenter study of women with biopsy-proven invasive lobular carcinoma. All patients had undergone diagnostic sonomammography. The imaging findings were identified by experienced breast imagers. Final surgical pathology results were used as the reference standard.
Results: Thirty-two women ranging in age from 42 to 63 years old (mean age, 53 years), All had biopsy-proven invasive lobular carcinomas. Common features on mammogram included dense mass followed by architectural distortion; three cases showed breast asymmetry and one case was reported as normal. On ultrasound, common features included solid mass with spiculated margins, posterior shadowing, and perpendicular to the skin.
Conclusion: Although no specific features could be linked to invasive lobular carcinoma, care should be directed to subtle signs such as architectural distortion and breast asymmetry in order not to miss any lesions. The combination of mammographic and sonographic helps to decrease the relatively high false negative diagnosis of this type of breast cancer.

Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) includes simple steatosis and metabolic dysfuncion-associated steatohepatitis (MASH), with fibrosis in MASH serving as a critical prognostic marker. This study investigates the effects of Roux-en-Y gastric bypass (RYGB) on fibrotic MASH, assessed using the fibrotic NASH index (FNI) and the non-invasive NASH detection score (NI-NASH-DS), as well as provides further data on the diagnostic accuracy of both scores.
Methods: A retrospective cohort study was conducted involving 104 individuals (91.
Invasive Lobular Carcinoma (ILC), a distinct subtype of breast cancer is hallmarked by E-Cadherin loss, slow proliferation, and strong hormone receptor positivity. ILC faces significant challenges in clinical management due to advanced stage at diagnosis, late recurrence, and development of resistance to endocrine therapy - a cornerstone of ILC treatment. To elucidate the mechanisms underlying endocrine resistance in ILC, ILC cell lines (MDA-MB-134-VI, SUM44PE) were generated to be resistant to tamoxifen, a selective estrogen receptor modulator.

Background The incidence of margin re-excision following breast conserving surgery (BCS) is a quality measure in the National Health Service. The threshold is less than 20% of all BCS procedures. Despite three decades of studies and a wealth of literature identifying multiple factors associated with increased risk for margin involvement, an accepted threshold rate affecting one in five procedures remains high.

Patients And Methods: Exploratory subgroup analysis of MINDACT trial patients with centrally assessed histology (n = 5929) with invasive breast cancer of no-special-type (NST), or pure ILC. In the trial patients were categorized based on the 70-gene signature for genomic risk and modified Adjuvant!Online for clinical risk.

To evaluate the neoadjuvant chemotherapy (NACTx) process in breast cancer (BC), its significant treatment-related adverse events (trAEs), tumor clinical response rates, and surgical and pathological outcomes, and to analyze factors influencing cavity shaving and axillary lymph node dissection (ALND) following sentinel lymph node biopsy (SLNB). A comprehensive retrospective study was conducted at a single center on patients who received NACTx for BC between 2015 and 2021. Medical records of 242 patients were reviewed.
