Whole-Exome Sequencing Analysis of the Progression from Non-Low Grade Ductal Carcinoma In Situ to Invasive Ductal Carcinoma.

CONCLUSIONS: Intra-lesion genetic heterogeneity is a common feature in DCIS synchronously diagnosed with IDC-NST. DCIS is a non-obligate precursor of IDC-NST, whose mechanisms of progression to invasive breast cancer are diverse and vary from case to case. PMID: 32220886 [PubMed - as supplied by publisher]

Conclusion: We improved the prediction performance of DCIS upstaging by embedding two related pathology classes in different training phases. Significance: The three new strategies of embedding related class data all outperformed the baseline model, thus demonstrating not only feature similarities among these different classes, but also the potential for improving classification by using other related classes.

CONCLUSION: These findings support the use of prophylactic NSM in high-risk patients. The nipples could be preserved in the majority of patients, postoperative complication rates were low, and, with limited follow-up, there were no new breast cancers.

CONCLUSION: CD133 may play an important role in the occurrence and development of breast cancer. CD133 positive breast cancer cells are closely related to invasiveness and its expression may predict a poor prognosis. PMID: 32390595 [PubMed - as supplied by publisher]

This study evaluated the histopathological features of ductal carcinoma in situ (DCIS), including cytological grade, architectural pattern and immunohistochemistry (IHC) in pure DCIS and DCIS associated with invasive carcinoma of no special type (ICNST). Methods: We evaluated a series of 232 cases of pure DCIS and DCIS associated with ICNST from a total of 399 breast carcinomas from a population consisting by women diagnosed with breast cancer and submitted to breast surgery from 2011 to 2015. Results: DCIS presented a mixed architectural pattern in most cases (56%); the solid subtype was the most common morphology (30%). ...

We present a rare case of Paget disease of the nipple without the typical characteristics, detected by simple nipple scraping technique. A 62-year-old woman presented with a small fissure on the left nipple with scant clear nippledischarge. There were no other changes to the nipple-areola complex. The mammography and ultrasound were unremarkable. However, nipplescraping provided the immediate cytological diagnosis of Paget disease. Breast MRI with core biopsy showed high grade ductal carcinoma in situwith suggestion of microinvasion, confirmed histologically after mastectomy. Nipple scraping is a simple and inexpensive tec...

If you dread your annual mammogram, you’re not alone. For many women, this breast cancer screening examination can be painful, stressful, and just an overall hassle. You may wonder, are you old enough to give it up? If you’re over age 75, the answer is: maybe or maybe not. The fact is, breast cancer screening isn’t right for all older adults, but there’s no expert consensus on the right age to stop. This is mostly because scientific evidence in this area is lacking, says Dr. Kathryn Rexrode, associate professor of medicine at Harvard Medical School and chief of the Division of Women’s Health a...

Getting the news that you have cancer is overwhelming and frightening. The COVID-19 crisis adds another layer of anxiety. But know this: you can protect yourself from COVID-19 without compromising your cancer treatment. Don’t panic. In the vast majority of cases, a diagnosis of cancer is not an emergency even though it feels like one. There is time to learn about your options and sort out what is right for you. For now, there will be changes to how we do things. Some of the changes will feel disruptive, but many will lead to better, more patient-centered care. Minimizing your chances of exposure to the virus doesn&rs...

AbstractPurposeBRCA2 mutation carriers are offered annual breast screening with MRI and mammography. The aim of this study was to investigate the supplemental value of mammographic screening over MRI screening alone.MethodsIn this multicenter study, proven BRCA2 mutation carriers, who developed breast cancer during screening using both digital mammography and state-of-art breast MRI, were identified. Clinical data were reviewed to classify cases in screen-detected and interval cancers. Imaging was reviewed to assess the diagnostic value of mammography and MRI, using the Breast Imaging and Data System (BI-RADS) classificati...
