Background: Triple-negative breast cancers lack expression of estrogen receptor, progesterone receptor, and human epidermal growth factor receptor -2. These tumors have been known to be clinically aggressive. We evaluate GATA-3, pAKT and Ki-67 expression in 35 triple negative breast carcinomas.Materials and Methods: A total of 35 triple negative breast carcinomas were included in this study. The histological subtyping was done according to Japanese guidelines for breast cancer.Results: GATA-3 was positive in 60% (21/35) of tumors. High GATA-3 expression was observed in ductal carcinoma in situ.  pAKT expression was demonstrated in 85.7 % (30/35) of TNBCs. The levels of expression of GATA-3 and pAKT showed no significant association with nuclear grading. (P=0.761 and P=0.487, respectively). Ki-67 labeling index was positively correlated with nuclear grading (p<0.001).Conclusion: GATA-3 expression has no relation with ER and PR expression and pAKT and GATA-3 are strongly expressed in TNBCs.

Abstract Background Triple-negative breast carcinoma (TNBC) patients do not benefit from hormone- or human epidermal growth factor receptor 2- (HER2-) targeted therapies. Accurate testing is pivotal for these patients. Methods TNBC cases that were retested at our institution during a 3-year period were evaluated for concordance rates in estrogen (ER) and progesterone (PR) receptor and HER2 results. Results We found 19 (22%) discrepancies (13 major/6 minor) among 86 cases. Minor discrepancies were in HER2 changes by immunohistochemistry, and all cases were demonstrated to be negative by and dual in situ hybridization. All major discrepancies were in ER/PR expression changes. In only 2 cases the treatment changed based on repeated results and/or patient history. Conclusions Discrepancies in prognostic/predictive testing continue to be frequent despite rigorous regulations. However, since for the majority of patients in our setting, the treatment plan did not change, reflex retesting for TNBC has been deemed unnecessary in our institution.

ObjectiveWe aimed to investigate the correlation of the perfusion parameters of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) with the molecular biological expression of breast infiltrating ductal carcinoma (IDC) in order to guide appropriate therapeutic advice and clinical outcome prediction.Materials and MethodsIn a prospective analysis of 67 patients with breast IDC, preoperative DCE-MRI and routine MRI images were obtained. The double-chamber model (extended Tofts model) was employed to calculate the perfusion parameters. Postoperative pathological immunohistochemistry was examined, including human epidermal growth factor receptor 2 (HER-2), estrogen receptor (ER), progesterone receptor (PR), cell nuclear-associated antigen (Ki-67), cytokeratin 5/6 (CK5/6), and epidermal growth factor receptor (EGFR). Statistical analysis was applied to explore the relationship between the perfusion parameters and the molecular biomarkers of breast cancer.ResultsA total of 67 lesions were included in our study. The mean maximum diameter of lesions was 4.48 ± 1.73 cm. Perfusion parameters had no correlation with tumor diameters (p &gt; 0.05). The volume transfer constant (Ktrans) and the rate constant (kep) had positive correlations with Ki-67 (p &lt; 0.05). The plasma volume ratio (vp) had a statistical difference between CK5/6 positivity and CK5/6 negativity. The maximum rising slope (MAX Slope) was higher in HER-2-enriched tumors than that in luminal A or B tumors (p &lt; 0.05). kep was higher in HER-2-enriched tumors than that in luminal A tumors (p &lt; 0.05). The extravascular extracellular space volume fraction (ve) was higher in triple-negative tumors than that in HER-2-enriched and in luminal A and B tumors (p &lt; 0.05). The time to peak enhancement (TTP) was lower in HER-2-enriched tumors than that in luminal A and B tumors (p &lt; 0.05). Maximum concentration (MAX Conc) was higher in triple-negative tumors than that in luminal B tumors (p &lt; 0.05).ConclusionDCE-MRI perfusion parameters can behave as a noninvasive tool to assess the molecular biological expression and the molecular subtypes of breast IDC. They may aid in predicting breast IDC invasiveness, metastasis, and prognosis.

Triple negative is a term applied to breast cancers that do not meaningfully express the estrogen or progesterone hormone receptors or overexpress the human epidermal growth factor receptor 2 tyrosine kinase. At present, the only proven method for systemic management of triple-negative breast cancer for both early-stage and metastatic settings is cytotoxic chemotherapy. Here, we provide a comprehensive review of management strategies that are best supported by available data. We also review recent advances most likely to affect treatment of triple-negative breast cancer in the coming years with particular emphasis on targeted agents, biologics, and immunotherapy.

Patients with human epidermal growth factor receptor 2 (HER2neu)-positive breast invasive cancer are known to have larger, more aggressive tumors. Little research exists on the relationship between HER2neu status and extent of ductal carcinoma in situ (DCIS). A retrospective review of a single-institution database was performed for patients with DCIS between the years 2002 and 2011. A single blinded breast radiologist reviewed preoperative imaging. Pathology was reviewed for extent of DCIS. Primary outcome was mastectomy. Multivariate logistic regression was used to determine adjusted mastectomy risk. There were 166 cases, 34 HER2neu-positive. HER2neu receptor-positive patients had larger lesions on imaging: 4.0 versus 2.7 cm, by 2.9 versus 1.5 cm ( P = 0.0499 and 0.0182). HER2neu-positive patients with DCIS were more likely than HER2neu-negative to undergo mastectomy than lumpectomy (53 vs 28%, P = 0.006). Pathology revealed a trend toward larger lesions in HER2neu-positive patients (2.96 vs 2.22 cm, nonsignificant). Patients with HER2neu-positive disease were three times more likely to undergo mastectomy (odds ratio, 2.9; 95% confidence interval, 1.23 to 6.78). Patients with HER2neu-positive DCIS had greater extent of disease by imaging and were more likely to undergo mastectomy than HER2neu-negative. These findings will help surgeons counsel patients on surgical treatment.

Breast cancer can recur even decades after the primary therapy. Markers are needed to predict cancer progression and the risk of late recurrence. The estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor-2 (HER2), proliferation marker Ki-67, and cytokeratin CK5 were studied to find out whether their expression or occurrence in subgroups of breast cancers correlated with the time of recurrence. The expression of HER2, ER, PR, Ki-67, and CK5 was studied by IHC in 72 primary breast cancers and their corresponding recurrent/metastatic lesions. The patients were divided into three groups according to the time of the recurrence/metastasis: before two years, after 5 years, and after 10 years. Based on their IHC profiles, the tumors were divided into surrogates of the genetically defined subgroups of breast cancers and the subtype definitions were as follows: luminal A (ER or PR+HER2–), luminal B (ER or PR+HER2+), HER2 overexpressing (ER–PR–HER2+), triple-negative (ER–PR–HER2–), basal-like (ER–PR–HER2–CK5+), non-classified (ER–PR–HER2–CK5–) and luminobasal (ER or PR+CK5+). In multivariate analysis, tumor size and HER2 positivity were a significant risk of early cancer relapse. The metastases showed a significantly lower CK5 expression. CK5 positivity distinguished triple negative tumors into rapidly and slowly recurring cancers. The IHC subtype ER or PR+HER2– luminal A presented a significantly lower risk of early tumor recurrence. Ki-67 expression denoted early-relapsing tumors and correlated linearly with tumor progression, since Ki-67 positivity declined gradually from early-relapsing toward late-recurring cancers.

Triple-negative breast cancers (TNBCs), negative for estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2, account for 15 to 20% of all female breast cancers. TNBC is heterogeneous based on gene expression microarray, and identification of TNBC subtypes and their behavior has the potential to enable more targeted, neoadjuvant, and adjuvant interventions. TNBCs usually are higher grade (Nottingham score 3) and are more common in younger, Hispanic, and African American women. They are more aggressive, have an increased likelihood of distant disease and mortality, are larger at presentation, and are more likely to be associated with lymph node metastases. Patients with TNBC are at a higher risk for visceral metastases early in the course of the disease. Genetic risk evaluation is recommended for patients with TNBC diagnosed at or before 60 years of age. Surgical management may be influenced by gene testing results. Standard adjuvant chemotherapy is anthracycline or taxane based. This review contains 5 figures, 8 tables, and 51 references. Key Words: adjuvant, BRCA, chemotherapy, hormone receptor negative, neoadjuvant, genetics, triple-negative breast cancer, breast neoplasm.
