Axillary evaluation is not warranted in patients preoperatively diagnosed with ductal carcinoma in situ by core needle biopsy

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 cancer (IBC). Positive axillary lymph nodes were identified in 41 (6.79%) patients. Predictors of upstaging included tumor size on ultrasonography (>2  cm) (OR 1.786,P = .002) and ER+HER2+ status (OR 1.874,P = .022) in multivariate analysis. Factors associated with axillary lymph nodes metastasis included tumor size on pathology (OR 2.336,P = .038) and number of lesions (OR 3.354,P = .039) in multivariate analysis. In addition, upstaging on final pathology had a significant influence on axillary lymph nodes status (P 2  cm), multifocal lesions or ER+HER2+ status. Despite of a 51.98% upstaging rate, the rate of axillary metastasis in these patients was relatively low, supporting the omission of axillary evaluation in selected patients with low risk of upstaging or axillary metastasis.

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...

Abstract Breast cancer is the most prevalent malignant tumor and main oncologic cause of mortality in women. Although most diagnosis of breast pathology is accomplished using hematoxylin and eosin stained sections, some cases require immunohistochemistry for proper evaluation. We investigated the latter cases including distinctions between ductal and lobular carcinoma, in situ and invasive carcinoma, typical ductal hyperplasia and atypical ductal hyperplasia/ductal carcinoma in situ, papillary and spindle cell lesion assessment, metastasis evaluation, and assessment of prognostic and therapy markers. E-cadherin is...

CONCLUSION: The high consistency between the features of primary DCIS and those of subsequent IBC (in the rare but not negligible cases of local failure) should be borne in mind when considering the therapeutic options. Treatment de-escalation and accrual of patients for active surveillance trials could be appropriate for luminal-like precursors. PMID: 31446852 [PubMed - as supplied by publisher]

.M. van Deurzen The underlying mechanism of the progression of ductal carcinoma in situ (DCIS), a non-obligate precursor of invasive breast cancer (IBC), has yet to be elucidated. In IBC, Apolipoprotein B mRNA Editing Enzyme, Catalytic Polypeptide-Like 3B (APOBEC3B) is upregulated in a substantial proportion of cases and is associated with higher mutational load and poor prognosis. However, APOBEC3B expression has never been studied in DCIS. We performed mRNA expression analysis of APOBEC3B in synchronous DCIS and IBC and surrounding normal cells. RNA was obtained from 53 patients. The tumors were categorized based on ...

Abstract PURPOSE: Ductal carcinoma in situ (DCIS) is widely recognized as the precursor of invasive ductal carcinoma (IDC). We aimed to analyze the clinicopathological characteristics and clinical outcomes of coexisting DCIS component in IDC and its clinical significance according to molecular subtypes. METHODS: Data from 3001 patients with IDC (79.4%) and IDC/DCIS (20.6%) who underwent surgery from January 2009 to June 2016 were retrospectively assessed. The clinical outcomes of IDC with coexistent DCIS in different molecular subtypes were evaluated. RESULTS: IDC/DCIS patients were more likely to be younger (P

CONCLUSION: This is the first reported Australian experience using neoadjuvant dual anti-HER2 and taxane therapy for HER-2 positive nonmetastatic breast cancer. The authors have demonstrated favorable pCR rates for invasive disease compared to the NEOSPHERE trial (68% vs 46%), with reasonable patient tolerability. Larger collaborative data sets are required to fully evaluate correlation of pCR with survival outcomes, and cost-effectiveness. National funding models need to be considered.

ConclusionsBreast cancer with concomitant PD was associated with more aggressive tumor characteristics and worse survival outcomes. The HR status, HER2 status, and combined molecular subtype could not affect the prognosis of breast cancer with PD. Moreover, a portion of the PD ‐DCIS cases were invasive breast cancer cases that required special treatment.

Conclusion MTDH is pro-oncogenic factor playing multifaceted and diverse roles in cancer progression. Its association and central role in regulating signaling pathways such a MAPK, wnt/β-catenin, PI3K/AkT, NF-κβ pathways in various cancers shows that it plays a vital role in metastasis. MTDH contribution to chemo and radiotherapy resistance provides a new direction for the development of anticancer therapeutics. Multiple mechanisms converge to promote expression of MTDH in cancers. Further studies are therefore warranted to determine whether the elevated MTDH expression has prognostic value for development...
