Malignant melanoma rarely originates from the female nipple. Tumors that develop on the skin of the breast are often subject to a delayed diagnosis. Cytologic examination provides excellent diagnostic capabilities and is a safe procedure with a lower risk of local implantation, compared to needle or incisional biopsy. We herein report a patient who underwent surgical resection of a primary malignant melanoma of the nipple. An elastic soft nodule was observed on the left nipple, and no abnormal lesions were identified in the breast...

In this study, we aimed to evaluate the economic loss due to the diagnosis of breast cancer within the female South Korean working-age population. A population-based cost analysis was performed for cancer-related diagnoses between 1999 and 2014, using respective public government funded databases. Among the five most common cancers, breast cancer mortality was strongly associated with the growth in gross domestic product between 1999 and 2014 (R=0.98). In the female population, breast cancer represented the greatest productivity loss among all cancers, which was a consequence of the peak in the incidence of breast cancer during mid-working age in the working-age population, in addition to being the most common and fastest growing cancer among South Korean women...

Triple-negative breast cancer (TNBC) has a higher risk of death within 5 years of being diagnosed than the other forms of breast cancer. It is the second leading cause of death due to cancer among women. Currently, however, no diagnostic blood-based biomarker exists to identify the early stages of TNBC. To address this point, we utilized a human protein microarray system to identify serum autoantibodies that showed different expression patterns between TNBC and normal serum samples, and identified five autoantibodies showing TNBC-specific expression...

Purpose: Vascular endothelial growth factor (VEGF) signal transduction mainly depends on its binding to VEGF receptor 2 (VEGFR-2). VEGF downstream signaling proteins mediate several of its effects in cancer progression, including those on tumor growth, metastasis, and blood vessel formation. The activation of VEGFR-2 signaling is a hallmark of and is considered a therapeutic target for breast cancer. Here, we report a study of the regulation of the VEGFR-2 signaling pathway by a small molecule, isomangiferin...

The Korean Breast Cancer Society (KBCS) has established a nationwide breast cancer database using an online registration program in 1996. The present study aimed to analyze the basic findings and trends of breast cancer in Korea in 2015 using the data provided by the Korea Central Cancer Registry and the KBCS. In 2015, a total of 22,550 patients were newly diagnosed with breast cancer, of which 3,331 were carcinoma in situ cases and 19,219 were invasive cancer cases. The incidence rate of breast cancer in Korea has steadily increased since the nationwide database was established, and the crude rate and age-standardized rate including that of carcinoma in situ , were 88...

Ectopic breast tissue and male breast cancer are both very rare diseases with only a few reports in the literature. Here, we present the first case of ectopic male breast cancer in the perineum. The patient was a 70-year-old man with a palpable mass in the perineum. A wide local excision and inguinal lymph node dissection revealed invasive breast carcinoma of no special type involving the skin and subcutis, and inguinal lymph node metastases. Immunohistochemical staining showed that the tumor cells were strongly positive for estrogen and progesterone receptors and negative for human epidermal growth factor receptor 2...

Two consecutive surveys for breast surgeons in Korea were conducted to comprehend the practice patterns and perceptions on margin status after breast-conserving surgery. The surveys were conducted online in 2014 (initial) and 2016 (follow-up). A total of 126 and 88 responses were obtained in the initial and follow-up survey, respectively. More than 80% of the respondents replied to routinely apply frozen section biopsy for intraoperative margin assessment in both surveys. Re-excision recommendations of the margin for invasive cancer significantly changed from a close margin to a positive margin over time ( p =0...

Purpose: Breast cancer has a high prevalence in Korea. To achieve personalized therapy for breast cancer, long-term follow-up specimens are needed for next-generation sequencing (NGS) and multigene analysis. Formalin-fixed paraffin-embedded (FFPE) samples are easier to store than fresh frozen (FF) samples. The objective of this study was to optimize RNA extraction from FFPE blocks for NGS. Methods: RNA quality from FF and FFPE tissues (n=5), expected RNA amount per unit area, the relationship between archiving time and quantity/quality of FFPE-extracted RNA (n=14), differences in quantitative real-time polymerase chain reaction (qRT-PCR) and NGS results, and comparisons of both techniques with tissue processing at different institutions (n=96) were determined in this study...
