Cancers, Vol. 12, Pages 609: Ductal Carcinoma In Situ of the Breast: An Update with Emphasis on Radiological and Morphological Features as Predictive Prognostic Factors Cancers doi: 10.3390/cancers12030609 Authors: Lucia Salvatorelli Lidia Puzzo Giada Maria Vecchio Rosario Caltabiano Valentina Virzì Gaetano Magro Ductal carcinoma in situ (DCIS) shows overlapping epidemiology with invasive ductal carcinoma of the breast, sharing similar risk factorssuch as age, mammographic density, family history, and hormonal therapy as well as genetic factors such as BRCA1/BRCA2, histotypes, and molecular subtypes such as luminal A and B, HER2 enriched, and basal-type, thus suggesting its potential precursor role. A small percentage of patients with a history of DCIS die without a documented intermediate diagnosis of invasive breast carcinoma (IBC). The increased risk of death is usually associated with ipsilateral recurrence such as IBC. The slightly variable incidence of DCIS in different countries is mainly due to a different diffusion of mammographic screening and variability of the risk factors. The majority of DCIS lesions are not palpable lesions, which can be only radiologically detected because of the association with microcalcifications. Mammography is a highly sensitive diagnostic procedure for detecting DCIS with microcalcifications, while magnetic resonance imaging (MRI) is considered more sensitive to detect DCIS without calcifications and/or multifoca...

CONCLUSIONS: Community-detected breast cancers were associated with increased government and out-of-pocket costs. Implications for public health: These costs should be considered when evaluating current and alternative breast cancer screening strategies. PMID: 32311194 [PubMed - as supplied by publisher]

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]

AbstractPurpose of ReviewBreast Ductal Carcinoma in Situ (DCIS) is an increasingly common diagnosis and already accounts for ~20% of screen-detected breast cancers. A subset of patients with DCIS will experience disease recurrence and some will die from breast cancer. Tailored strategies for treatment are lacking at this time. Human Epidermal Growth Factor Receptor 2 (HER2) is a tumor associated antigen that is shown to correlate with poorer outcomes among patients with early breast cancer, including DCIS. Significant interactions between the humoral and cellular branches of the immune system were observed in tumorigenesis...

In this study, we aimed to evaluate the prognostic significance of CTSV in DCIS. METHODS: CTSV protein expression was immunohistochemically assessed in a well-characterised and annotated cohort of DCIS comprising pure DCIS (n=776) and DCIS coexisting with IBC (n=239). CTSV expression was analysed in tumour cells and surrounding stroma, including its association with clinicopathological parameters and outcome. RESULTS: In pure DCIS, high CTSV expression was observed in 29% of epithelial tumour cells and 20% of surrounding stroma. High expression in both components was associated with features of poor prognosis inc...

ConclusionThis demonstrates procoagulant phenotypic changes occur in fibroblasts at the preinvasive stage. Fibroblast procoagulant phenotype is associated with aggressive breast cancer subtypes and reduced survival. Coagulation may be a therapeutic target in breast cancer.

Authors: Zheng J, Zhou T, Li F, Shi J, Zhang L Abstract Background: To investigate the differences of clinic-pathological features among ductal carcinoma in situ (DCIS), ductal carcinoma in situ with micro-invasion (DCIS-MI) and early invasive carcinoma (IDC) in stage T1.Methods: From January 2014 to December 2018, 308 cases DCIS, DCIS-MI 92 cases and 111 cases of T1a, 343 cases of T1b, and 1032 cases of T1c were investigated in a retrospective analysis. The population and clinic-pathological characteristics including age, menstrual status, surgical mode, lymph node status and molecular markers were compared in eac...

Conclusions: Targeting mTORC1 can inhibit DCIS progression to IDC via MMP9 and may be a potential strategy for DCIS or Early-Stage IDC therapy. PMID: 31871301 [PubMed - as supplied by publisher]

AbstractThe risk of radiotherapy-induced malignancies (RIMs) is a concern when treating Li –Fraumeni syndrome (LFS) or Li–Fraumeni Like (LFL) patients. However, the type ofTP53 pathogenic germline variant may possibly influence this risk.TP53 p.R337H mutation is particularly prevalent in Brazil. We aimed to evaluate the outcomes of patients with pathogenicTP53 variants treated for localized breast cancer in a Brazilian cohort. We evaluated retrospectively a cohort of patients with germlineTP53 pathogenic variants treated for localized breast cancer between December 1999 and October 2017. All patients were follo...

AbstractS100A10 promotes tumor invasion in various cancers. Although genetic studies on S100A10 in breast carcinoma (BC) have been used for molecular biological classification, immunohistochemical studies are lacking. We aimed to identify the correlation between S100A10 expression in BC and various pathological parameters, including morphological features to determine histological grade (HG). Immunostained serial paraffin-embedded tissue sections from 176 cases of resected BC or normal mammary ducts (controls) were assessed for the membrane expression of S100A10. Of the 176 cases, 125 conventional infiltrating ductal carci...

This study sought to identify clinicopathological factors associated with upstaging and axillary metastasis in patients preoperatively diagnosed with DCIS by CNB.Materials and MethodsThis study identified 604 patients (cT1 ‐3N0M0) with preoperative diagnosis of pure DCIS by CNB who had undergone axillary evaluation from August 2006 to December 2015 at Fudan University Shanghai Cancer Center (FUSCC). Predictors of upstaging and axillary lymph nodes metastasis were analyzed, respectively.ResultsOf all 604 patients, 121 (20.03%) and 193 (31.95%) patients were upstaged to DCIS with microinvasion (DCISM) and invasive breast c...
