Both anastrozole and tamoxifen were effective at preventing recurrence of breast cancer in postmenopausal women with ductal carcinoma in situ. Age, toxicities should drive choice, say investigators. Medscape Medical News

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]

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]

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]

Abstract PURPOSE: Primary endocrine therapy for ductal carcinoma in situ (DCIS) as a potential alternative to surgery has been understudied. This trial explored the feasibility of a short-term course of letrozole and sought to determine whether treatment results in measurable radiographic and biologic changes in estrogen receptor (ER)-positive DCIS. PATIENTS AND METHODS: A phase II single-arm multicenter cooperative-group trial was conducted in postmenopausal patients diagnosed with ER-positive DCIS without invasion. Patients were treated with letrozole 2.5 mg per day for 6 months before surgery. Breast magne...

Conclusion: Our results demonstrate persistent use of advanced imaging tests for routine metastatic screening among patients with stage 0–II breast cancer despite the release of the ASCO Choosing Wisely recommendations and the update of our provincial breast cancer staging guideline. Investigation of strategies for guideline translation to improve upon value-based care of patients with early breast cancer is warranted. PMID: 32109016 [PubMed - as supplied by publisher]
