Meeting Highlights: The Second Consensus Conference for Breast Cancer Treatment in Korea.
Discussions on radiotherapy addressed the need for adjuvant radiotherapy and radiation field of regional lymph node in the context of various N1 breast cancer cases. The participants reached a consensus to recommend that N1 patients should receive regional nodal irradiation for a large tumor burden (e.g., three positive nodes, perinodal extension, or large primary tumor). Finally, the panels favored OFS in addition to endocrine therapy for premenopausal women with high risk factors such as a large tumor size, involvement of more than three nodes, and a high histologic grade.

Crotonis Fructus Extract Inhibits 12-O-Tetradecanoylphorbol-13-Acetate-Induced Expression of Matrix Metalloproteinase-9 via the Activator Protein-1 Pathway in MCF-7 Cells.
CONCLUSION: The results indicated that the inhibitory effects of CFE against TPA-induced MMP-9 expression and MCF-7 cell invasion were dependent on the protein kinase C δ/p38/c-Jun N-terminal kinase/AP-1 pathway. Therefore, CFE could restrict breast cancer invasiveness owing to its ability to inhibit MMP-9 activity. PMID: 28970848 [PubMed] (Source: Journal of Breast Cancer)

Gene Regulatory Network Analysis for Triple-Negative Breast Neoplasms by Using Gene Expression Data.
CONCLUSION: Our TNBN gene regulatory network was a scale-free one, which means that the network would be easily destroyed if the hub vertices were attacked. Thus, it is important to identify the hub vertices in the network analysis. In the TNBN gene regulatory network, ZDHHC20 and RAPGEF6 were found to be oncogenes. Further study of these genes could help to reveal a novel method for treating TNBN in the future. PMID: 28970849 [PubMed] (Source: Journal of Breast Cancer)

Copy Number Profiling of MammaPrint ™ Genes Reveals Association with the Prognosis of Breast Cancer Patients.
CONCLUSION: Based on these findings, a concordance of CNV-based genomic rearrangement with expression profiling of these genes and their putative roles in disease tumorigenesis was established. The results suggested that the CNV profiles of the MammaPrint™ genes can be used to predict the prognosis of breast cancer patients. In addition, this approach may lead to the development of new cancer biomarkers at the DNA level. PMID: 28970850 [PubMed] (Source: Journal of Breast Cancer)

Prognostic Influence of Preoperative Fibrinogen to Albumin Ratio for Breast Cancer.
Authors: Hwang KT, Chung JK, Roh EY, Kim J, Oh S, Kim YA, Rhu J, Kim S Abstract PURPOSE: Elevated serum concentration of fibrinogen and decreased serum concentration of albumin have been reported to be markers of elevated systemic inflammation. We attempted to investigate the prognostic influence of preoperative fibrinogen to albumin ratio (FAR) for breast cancer. METHODS: Data from 793 consecutive primary breast cancer patients were retrospectively analyzed. Serum levels of fibrinogen and albumin were tested before curative surgery.

Follow-up Outcomes of Benign Pathology Initially Assigned as Breast Imaging Reporting and Data System Category 4A and 3.
CONCLUSION: The initial category 4A or 3 of the Breast Imaging Reporting and Data System could be a significant factor that affects immediate surgical excision and follow-up compliance. Cancers were detected only in the initial category 4A group of concordant benign lesions. More attention should be paid to the concordant benign lesions from the initial category 4A group than from the category 3 group. PMID: 28970857 [PubMed] (Source: Journal of Breast Cancer)

A Novel Germline Mutation in BRCA1 Causes Exon 20 Skipping in a Korean Family with a History of Breast Cancer.
This report describes a family with a history of breast and ovarian cancers that harbored a novel BRCA1 germline mutation. A single nucleotide deletion in intron 20, namely c.5332+4delA, was detected in a 43-year-old patient with breast cancer. This mutation led to the skipping of exon 20, which in turn resulted in the production of a truncated BRCA1 protein that was 1773 amino acids in length. The mother of the proband had died due to ovarian cancer and had harbored the same germline mutation. Ectopically expressed mutant BRCA1 protein interacted with the BARD1 protein, but showed a reduced transcriptional function, as de...

Invasive Micropapillary Carcinoma in Axillary Ectopic Breast and Synchronous Ductal Carcinoma In Situ in the Contralateral Breast.
Authors: Oh SW, Lim HS, Lee JS, Moon SM, Park MH Abstract The development of ectopic breast tissue is attributable to the failure of primitive mammary tissue to regress after the development of the mammary ridge, except at pectoral breast sites, and is most often evident in the axillae. Several benign and malignant breast diseases have been reported in ectopic axillary breast tissues. The most common cancerous pathology of ectopic breast tissue is invasive ductal carcinoma. Ectopic breast cancer presenting with simultaneous primary cancer of the pectoral breast is extremely rare. Herein, we report an invasive micro...

Recent Advances in the Neoadjuvant Treatment of Breast Cancer.
Authors: Rubovszky G, Horváth Z Abstract In the last few decades, neoadjuvant therapy for breast cancer has gained considerable therapeutic importance. Despite extensive clinical investigations, it has not yet been clarified whether neoadjuvant therapy would result in improved survival in comparison with the standard adjuvant setting in any subgroups of patients with breast cancer. Chemotherapy is especially effective in the treatment of endocrine insensitive tumors, and such ther-apeutic benefit can be assumed for patients with triple-negative, or hormone receptor-negative and human epidermal growth factor ...

Overexpression of Uridine-Cytidine Kinase 2 Correlates with Breast Cancer Progression and Poor Prognosis.
Authors: Shen G, He P, Mao Y, Li P, Luh F, Ding G, Liu X, Yen Y Abstract PURPOSE: Uridine-cytidine kinase (UCK) 2 is a rate-limiting enzyme involved in the salvage pathway of pyrimidine-nucleotide biosynthesis. Recent studies have shown that UCK2 is overexpressed in many types of cancer and may play a crucial role in activating antitumor prodrugs in human cancer cells. In the current study, we evaluated the potential prognostic value of UCK2 in breast cancer. METHODS: We searched public databases to explore associations between UCK2 gene expression and clinical parameters in patients with breast cancer. Gene se...

CD49f Can Act as a Biomarker for Local or Distant Recurrence in Breast Cancer.
CONCLUSION: Our results indicated that breast tumors with CD49f(+) cancer cells are associated with an increased risk for disease recurrence after initial surgery with poor clinical outcomes (decreased DFS). Therefore, as it requires testing for only one additional protein, adding CD49f testing to conventional surgical pathology is a strategy that has great potential for prognostic and treatment-guidance purposes.

CONCLUSION: Most recurrent breast cancers showed the same cancer subtype as the primary tumor, and recurrent breast cancer subtypes correlated with the detection modality. Imaging surveillance of survivors of breast cancer might be more beneficial in cases of HR+HER2- type breast cancer or HER2+ type breast cancer than in cases of triple-negative type breast cancer.

Epigenetic Silencing of MORT Is an Early Event in Cancer and Is Associated with Luminal, Receptor Positive Breast Tumor Subtypes.
This study evaluated the epigenetic and transcriptional state of MORT in two premalignant conditions-ductal carcinomas in situ and colon adenomas. Results show that MORT silencing is an early epigenetic event in human carcinogenesis, likely occurring near the point where premalignant cells gain immortality; this epigenetic silencing is maintained throughout malignant transformation and metastatic growth. Additional associations between MORT loss and clinical and molecular features of breast tumors showed that silencing of MORT occurs predominantly in luminal, receptor-positive breast cancer; is associated with overexpressi...
