CONCLUSIONS: In conclusion, male DCIS frequently shows activated hypoxia response, comparable to male IC. This indicates that the activated hypoxia response previously seen in male IC is not a late bystander but likely a genuine carcinogenetic event. PMID: 31653758 [PubMed - indexed for MEDLINE]

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]

Abstract Among lesions with uncertain malignant potential found at percutaneous breast biopsy, atypical ductal hyperplasia (ADH) carries both the highest risk of underestimation and the closest and most pathologist-dependent differential diagnosis with ductal carcinoma in situ (DCIS), matching the latter's features save for size only. ADH is therefore routinely surgically excised, but single-centre studies with limited sample size found low rates of upgrade to invasive cancer or DCIS. This suggests the possibility of surveillance over surgery in selected subgroups, considering the 2% threshold allowing for follow-...

n Jing Wang To characterize molecular changes accompanying the stepwise progression to breast cancer and to identify functional target pathways, we performed miRNA and RNA sequencing using MCF10A cell lines based model system that replicates the multi-step progression involving normal, preneoplastic, ductal carcinoma in situ, and invasive carcinoma cells, where the carcinoma most resemble the basal-like subgroup of human breast cancers. These analyses suggest that 70% of miRNA alterations occurred during the initial progression from normal to a preneoplastic stage. Most of these early changes reflected a global upreg...

Authors: Mori N, Mugikura S, Miyashita M, Mori Y, Maekawa Y, Nagasaka T, Takase K Abstract PURPOSE: To compare the image quality between turbo spin-echo (TSE)-diffusion weighted imaging (DWI) and single-shot echo-planar imaging (EPI)-DWI, and to verify the diagnostic performance of the apparent diffusion coefficient (ADC) parameters of the two techniques by using histogram analysis in terms of differentiation between ductal carcinoma in situ (DCIS) and invasive ductal carcinoma (IDC) lesions. METHODS: Ninety-four women with 94 lesions diagnosed as breast cancer by surgery underwent IRB-approved preoperative mag...

CONCLUSIONS: MBC has increasing incidence. PR-negative status was associated with better overall survival and disease-free interval. Indications to radiotherapy and hormonal therapy need standardization and will benefit from prospective randomized control trials. PMID: 32147980 [PubMed - in process]

The aim of this study was to identify the key differentially expressed genes (DEGs) and high-risk gene mutations in breast ductal carcinoma in situ (DCIS).

In conclusion, LOY is an early event in male breast carcinogenesis, which generally starts at the DCIS stage and is associated with ER and PR negative tumors.

We report the development of a robotic nipple-sparing mastectomy with immediate reconstruction through a single incision using the updated single-port surgical robot system for a patient with ductal carcinoma in situ (DCIS). Breast reconstruction was performed using implants. Postoperative pathological examination revealed DCIS in both breasts. There were no major immediate complications, except for a minor skin burn on the right breast. Overall, the initial operation using the updated platform was safely performed. PMID: 32140275 [PubMed]
