Incremental advances over the last two decades in the treatment of stage IV metastatic breast cancer (MBC) have resulted in significantly prolonging the average life expectancy. In 2008, the estimated 5-year relative survival rate for MBC is 27% which compares favorably to rates in stage IV lung (3%) and pancreatic cancers (1%). Despite these advances, MBC remains an incurable disease, often as...

BACKGROUND The measurement of circulating cell-free DNA (cfDNA) may transform the management of breast cancer patients. We aimed to investigate the clinical significance of sequential measurements of ESR1 mutations in primary breast cancer (PBC) and metastatic breast cancer (MBC) patients. RESULTS ESR1 mutations ratio in the PBC groups was used as the minimum cutoff for determining increases ...

A coumarin analogue, 8-methoxy-4-methyl-2H-benzo[g]chromen-2-one (MMBC), is almost non-fluorescent in non-polar media, whereas it exhibits dramatically enhanced fluorescence in polar protic solvents. This study investigates the mechanistic features of the significant solvent effects on the fluorescence properties of MMBC and a related compound, 4-methyl-2H-benzo[g]chromen-2-one (MBC), by time-r...

AIM The aim of this study was to evaluate the minimum bactericidal concentrations (MBC) of root-end filling materials ProRoot MTA, MTA Angelus and IRM. MATERIALS AND METHODS Macrodilution broth method was used. Microorganisms used were: Staphylococcus aureus (ATCC 29213), Enterococcus faecalis (ATCC 29212) and Streptococcus mutans. Serial two-fold dilutions of root-end filling samples were pr...

PURPOSE Breast cancer treatment has progressed significantly over the past 20 years. However, knowledge regarding male breast cancer (MBC) is sparse because of its rarity. This study is an investigation of the clinicopathologic features, treatments, and clinical outcomes of MBC. MATERIALS AND METHODS Clinical records of 59 MBC patients diagnosed during 1995-2014 from seven institutions in Kor...

BACKGROUND The androgen receptor (AR) expression and the CAG repeat length within the AR gene appear to be involved in the carcinogenesis of male breast carcinoma (MBC). Although phenotypic differences have been observed between MBC and normal control group in AR gene, there is lack of correlation analysis between AR expression and CAG repeat length in MBC. The purpose of the study was to inves...

Introduction: Metaplastic breast cancer (MBC) is a rare pathological type with an incidence rate of not more than 1%, and has been reported to be often detected after its progression and highly malignant with a high proportion of triple negative type tumors, with poor outcomes as compared to IDC [1] [2] [3]. We analyzed clinicopathological characteristics of patients who underwent surgery for e...

Major hepatectomy (MH) is often considered the only possible approach for colorectal liver metastasis (CRLM) at the hepato-caval confluence (CC), but it is associated with high morbidity and mortality. With the aim to reduce MH, we developed the "minor-but-complex" (MbC) technique, which consists in the resection of less than 3 adjacent liver segments with exposure of the CC and preservation of...

Metaplastic breast carcinoma (MBC) is an uncommon malignancy characterized by the co-existence of two or more cellular types, commonly a mixture of epithelial and mesenchymal components. A case of a female patient aged 46 years with MBC (carcinosarcoma) is presented, including mammographic, ultrasonic, gross examination, and pathological findings. After undergoing modified radical mastectomy of...

In this paper, we present a scheme that possess seamless channel transition property and is suitable for heterogeneous receivers simultaneously. We first modify the BroadCatch (MBC) scheme [28][29] by allowing an arbitrary number of base channels defined in BroadCatch. We then propose a seamless channel transition enhancement on top of MBC so that service provider can be capable of adjusting th...
