BACKGROUND: The recent investigations have rendered microRNAs (miRs) as a novel biomarker in cancer research. In fact, alteration in miR expression may be associated with tumor suppression, tumorigenesis, metastasis, and poor prognosis in human breast cancer (BC). OBJECTIVES: The aim of this clinical experimental study was to measure the miR-328 expression level in breast cancer tissues, at first. Then, we tried to find out any possible correlation between miR-328 and prognostic and predictive biomarkers in BC...

Papillary breast lesions are a heterogeneous group of tumors which mainly arise in the central mammary region, ranging from benign to malignant. Among them, solid papillary carcinoma (SPC) represents a very uncommon variant with indolent clinical behavior and excellent prognosis. The categorization of papillary lesions as benign, atypical or malignant is often difficult even for experienced pathologists. Furthermore, for prognostic purposes, to decide whether to consider a lesions as in situ when it is not associated with frank invasive foci of carcinoma may be problematic...

BACKGROUND: The role of postmastectomy radiotherapy (PMRT) for women with pT3N0M0 breast cancer is controversial. We sought to determine the benefit of PMRT in this cohort using the National Cancer Database (NCDB). METHODS: We analyzed women with pT3N0M0 breast cancer who received mastectomy with or without PMRT between 2004 and 2012. We excluded men, women ≤18 years, neoadjuvant or unknown radiation or chemotherapy status, unknown estrogen or progesterone receptor status, unknown surgical margin status, histology other than invasive ductal or lobular carcinoma, and if death occurred <3 months after diagnosis...

Oncotype Dx is used to determine the recurrence risk (RR) in patients with estrogen receptor positive (ER+) and lymph node negative (LN-) breast cancer. The RR is divided into low (0-17), intermediate (18-30), and high (31) to predict chemotherapy benefit. Our goal was to determine the association between histomorphology, immunohistochemistry, and RR. We retrospectively identified 536 patients with ER+ and LN- breast cancers that underwent Oncotype testing from 2006 to 2013. Tumor size ranged from 0.2 cm to 6...

: 88 Background: System inefficiencies result in delayed breast cancer diagnoses. Inefficiencies include any non-value added steps between symptom onset/imaging abnormality to cancer diagnosis and treatment. Diagnostic delays can lead to more advanced disease and may negatively impact survival. Further, optimizing the efficiency of diagnostic evaluation models can reduce barriers to care and improve patient satisfaction. To achieve these efficiency goals, Banner MD Anderson Cancer Center (BMDACC) instituted the Undiagnosed Breast Clinic (UBC)...

A 90-year-old woman was referred to our hospital because of abdominal distension and pretibial edema. No tumors were palpable in either breast. Her abdomen was distended and palpitation was noticed. Laboratory examination revealed hypercalcemia and elevated levels of tumor markers(PIVKA- II , CEA, CA19-9, SCC). Contrast-enhanced computed tomography(CT) showed pleural effusion and ascites, an approximately 17-mm high-contrast mass in the D area of the left breast, and osteolysis of the dorsal lumber spine. We initiated treatment for pleural effusion, ascites, and hypercalcemia...

We report a case of recurrent breast cancer with involvement of the right adrenal grand, which was resected using laparoscopic surgery. The patient was a 41-year-old woman who underwent duct-lobular segmentectomy for ductal carcinoma in situ. Histopathology showed microinvasion, and tested positive for ER and PR, but negative for HER2, so we applied radiation to the remaining breast and administered tamoxifen. After 9 months, local recurrence was detected and quadrantectomy with axillary lymph node dissection was performed...

A49 -year-old woman presented with a 3.5 cm mass in her right breast. Mammography revealed a lobular mass with poorly defined margins and no microcalcification. Ultrasonography showed a hypoechoic mass with an irregular margin. The tumor was diagnosed as breast carcinoma using a core needle biopsy. The patient underwent a modified radical mastectomy with sentinel lymph node biopsy, and received adjuvant chemotherapy. The tumor consisted of 2 types of carcinoma. The center of the tumor was solid-tubular carcinoma, and the periphery was acinic cell carcinoma(ACC)...

BACKGROUND: The phrase "high-risk for breast cancer" is used to identify various groups at elevated cancer risk, and the appropriate surveillance and risk-reducing strategies differ based on the etiology of risk. Here, we review the utility of patient-reported data to capture women with modifiable lifestyle risk factors and those suitable for genetic counseling referral. METHODS: Patient-reported data from a web-based survey were used to capture personal history, multi-generational family history, and lifestyle factors (body mass index, alcohol consumption, physical activity)...

INTRODUCTION: Differentiating between primary and secondary ovarian cancer can be a difficult task. In hereditary conditions breast malignancies and primary ovarian cancer often coexist. PRESENTATION OF CASE: We present a 45-year-old patient with an ovarian mass two years after the diagnosis of a lobular, triple negative breast carcinoma. There was concern whether the lesion represented a metachronous ovarian cancer or a metastasis of the lobular carcinoma. The final histological examination showed a metastatic lesion, deriving from the lobular breast carcinoma, as evidenced by the immunohistochemical profile; nevertheless, there were changes in hormonal receptor expression in the metastatic lesion compared to the primary, triple negative tumor...

BACKGROUND: Invasive lobular carcinoma (ILC) is known to be the second most common histological type following invasive ductal carcinoma (IDC). Definitive clinical features of ILC are controversial. METHODS: We retrospectively analyzed a cohort of 330 patients with metastatic breast cancer, 303 of IDC, 19 of ILC, and 8 of others. We compared the patient age and tumor-node-metastasis factors, disease-free survival (DFS), estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor 2 (HER2) expression at the primary site between ILC and IDC...

Pleomorphic lobular carcinoma in situ (PLCIS) has only recently been identified as a distinct pathological entity within classic lobular carcinoma in situ (CLCIS). As such, there is currently no consensus among clinicians regarding the optimal treatment of this disease. The present study determined the risk of concomitant invasive disease and ductal carcinoma in situ (DCIS) if PLCIS is observed on core needle biopsy (CNB) and collated the evidence regarding the risk of recurrence in relation to surgical margins and adjuvant therapy...

The Oncotype DX breast cancer assay (Genomic Health, Redwood City, CA) is increasingly being used to guide treatment decisions for patients with early stage, hormone-positive, Her-2-negative breast cancer. The utility of the Oncotype DX in decision making for treatment of invasive lobular carcinoma (ILC) has not been investigated as the results reported by Genomic Health are largely in a population with invasive ductal carcinoma (IDC). The authors hypothesized that the Oncotype DX recurrence score (RS) distribution for ILC is different than that for IDC...

Gastrointestinal metastases from breast cancer are not common. We present a 58-year-old female diagnosed with lobular breast cancer some years before whose relapses were gastric and colonic mucosal. Simultaneous metastases are extremely rare. To our knowledge, no cases of initial dual affectation have been reported. The patient also showed gastritis by Helicobacter pylori. Invasive lobular breast carcinoma is the most frequent special type of breast cancer and carries some specific molecular alterations such as loss of expression of E-cadherin...
