This study was conducted to estimate incidence rate of female breast cancer in a defined area of Chungchongbuk-do in Korea. The presumptive breast cancer cases were selected from two different sources, i.e., medical utilization database of the National Health Insurance Corporation and the database from the National Cancer Registry. Medical students visited each hospital where the presumptive cases had been treated as a breast cancer patient, and made a dictation of medical record of each patient based on the claims stored in the Insurance Corporation from January to December 1995. The diagnoses in the claims included one of the following diagnostic codes; ICD-9 174-175(malignant neoplasms of the breast), 233(carcinoma in situ of the breast and genito-urinary system)or ICD-10 C50(malignant neoplasms of the breast), D05(carcinoma in situ of the breast and genito-urinary system). Each case has been confirmed as having a breast cancer by a breast surgeon through a medical record review. Age-standardized incidence rate of female breast cancer to the Korean population was estimated to be 10.5(95%confidence interval : 8.1-12.9)per 100,000 persons in 1995. Age-standardized rate to the world population was 9.8 per 100,000 persons, and the truncated rate for ages 35-64 was 27.2 per 100,000 persons. Validity of these estimates is discussing in comparison with previous methods of incidence estimation in Korea.

Cowden syndrome (CS), also known as multiple hamartomas syndrome, is a rare hereditary autosomal dominant disorder caused by a germline mutation in the phosphatase and tensin homolog (PTEN) gene mapped on chromosome 10. The clinical features of CS are variable, primarily presenting as mucocutaneous lesions (99%). A mucocutaneous lesion, such as trichilemmoma of the face or keratosis of the extremities, is an important diagnostic marker for CS. CS has been reported to increase the incidence of benign and malignant neoplasms in the breast, thyroid, and gastrointestinal tract. The risk of developing malignancy in individuals with CS is up to 10 times higher than general population throughout an entire life time.

유방암 환자의 흉막 전이는 흔한 소견이다. 흉수가 가장 흔한 증상이고 흉수를 동반하지 않는 흉막 결절이나 흉막 판은 비교적 드물다. 본 환자는 말기 유방암으로 인해 흉수를 동반하지 않는 빠른 속도로 악화되는 거대 흉막 종양이 생겨났고 그로 인해 심한 호흡곤란을 경험했던 환자로 보기 드문 증례로서 보고를 하며 이와함께 말기암환자의 호흡곤란의 치료에 대해 고찰해 보고자 한다.

Purpose: The purpose of this study was to explore the association between breastfeeding and the prevalence of breast, thyroid, and cervical cancer among Korean adult women. Methods: The study was a secondary analysis of data from the Korea Genome and Epidemiology Study. The final samples were 113,944 Korean women among 173,205 urban-based cohort participants collected between 2004 and 2013 for adults aged forty and over. To determine the association between female cancers and breastfeeding experience, the number of childbirth, and total breastfeeding duration, logistic regression analysis was done. The demographic characteristics, health behavior, and female history were adjusted. Results: The prevalence of breast cancer was 1.37 times higher in the non-breastfeeding group than in the breastfeeding group. Compared to having breastfed for more than 36 months, the prevalence of thyroid cancer was 1.68 times higher at breastfeeding for 13 to 36 months, 1.67 times higher at breastfeeding for 6 to 12 months, and 2.06 times higher at breastfeeding less than 6 months. Also, the prevalence of cervical cancer was 1.54 times higher at breastfeeding for 13 to 36 months, compared to breastfeeding for more than 36 months. Conclusion: The study found that breastfeeding experience and a longer breastfeeding duration are associated with reduced risk of breast, thyroid, and cervical cancer in Korean women. It can be used as a basis for encouraging breastfeeding, and suggests further research on modifiable factors that reduce cancer risks.

다발성 원발성 악성 종양은 한 환자에서 2개 이상의 원발성 악성 종양이 각각 독립적으로 발생하는 경우를 말한다. 저자들은 78세 남자 환자에서 동시에 발생한 유방의 점액성 선암과 유방외 림프종의 증례를 경험하여 보고하고자 한다. 환자는 2개의 만져지는 덩이를 주소로 내원하여 외과적 생검을 통해 좌측 유방의 점액성 선암과 우측 서혜부의 미만성 거대 B세포 림프종을 확진하였다. 이후 수술 전 시행한 PET/CT에서 좌측 혀편도의 우연종이 발견되었고, 절제 생검을 통해 미만성 거대 B세포 림프종을 확진하였다. 유방암 환자에서 불특정한 림프절 비대가 발견되는 경우 전이성 병변으로 간주되기 쉬우나, 이 증례의 환자와 같이 고령의 환자군에서는 림프종을 감별 진단으로 함께 고려함으로써 오진 및 치료 지연을 방지할 수 있을 것이다.

Lipofilling is a reconstructive and aesthetic technique that has recently grown in popularity and is increasingly being used in breast surgery. Previous concerns had been raised regarding its safety when used for remodelling and reconstruction of the breast; however, these concerns have since been dismissed. Over the subsequent two decades, little evidence has been found to support these early theoretical concerns, and growing numbers of proponents of the procedure are confident in its safety. Many developments and refinements in the technique have taken place in recent years, and several studies have been published regarding the safety of lipofilling in the breast. We reviewed the current literature regarding the use of different lipofilling techniques as well as the current evidence regarding the oncological safety of the procedure in patients seeking aesthetic breast enhancement and in patients requiring reconstruction after treatment for breast cancer.

남성 유방암은 드물며 유방암의 약 1%를 차지한다. 유방 외 악성 종양이 남성 유방으로의 전이는 매우 드물다. 남자에서 유방으로 전이되는 가장 흔한 원발성 종양은 전립선암, 폐암, 위암, 대장암, 흑색종 및 육종이다. 남자에서 방광암의 유방으로의 전이 유방암은 드물게 보고되었고, 종괴가 아닌 침윤성 소견의 전이 소견을 보이는 경우는 매우 드물다. 방광암이 유방으로 전이된 59세 남자 환자의 유방촬영술 및 초음파에서의 영상 소견을 보고하고자 한다.

Objectives: This study investigated the association between menopausal-specific quality of life (MENQOL) and breast cancer screening beliefs among Hong Kong Chinese menopausal and postmenopausal women. Methods: A cross-sectional study was employed to collect data. The questionnaire was distributed to a convenience sample of 218 women aged above 45. The outcome variables were breast cancer screening beliefs and breast examination. Multiple regression analyses were conducted to test the effect of 4 domains in MENQOL (vasomotor, psycho-social, physical, and sexual symptom) and the health behaviors on the 2 outcome variables. Results: This study found that the overall MENQOL scores (in particular psycho-social, and physical aspects) were significantly associated with positive attitudes toward health check-ups and better knowledge and perceptions in breast cancer. Regular exercise was also significantly related to breast examination. Conclusions: MENQOL (especially psycho-social and physical domain) and regular exercise are important factors associated with breast cancer screening beliefs. The results of this study illuminate health care professionals to develop primary health care strategies to improve the quality of life of mid-life women.

Cancer is the leading cause of death worldwide. In developed as well as developing countries, breast cancer is the most common cancer found among women. Currently, treatment of breast cancer consists mainly of surgery, chemotherapy, hormone therapy, and radiotherapy. In recent years, because of increased understanding of the therapeutic potential of immunotherapy in cancer prevention, cancer vaccines have gained importance. Here, we review various immunotherapeutic breast cancer vaccines including peptide-based vaccines, whole tumor cell vaccines, gene-based vaccines, and dendritic cell vaccines. We also discuss novel nanotechnology-based approaches to improving breast cancer vaccine efficiency.

Metastasis from primary cancer to the thyroid is uncommon in breast cancer. Here we present a case of lobular breast carcinoma that metastasized to the thyroid. A 54-year-old woman without symptoms was admitted to our institution for staging of the lymph node above the left clavicle. An $^{18}F$-fluoro-deoxy-D-glucose positron emission tomography scan was performed for staging, and low uptakes were observed in the left supraclavicular and cervical lymph nodes. High uptake was seen in the posterior and lower left lobe of the thyroid. Histologic findings indicated lobular breast carcinoma (positive GATA3, loss of E-cadherin expression) metastatic to the thyroid with a luminal profile. Immunohistochemical analysis was negative for primary thyroid or parathyroid carcinoma. To our knowledge, this is the first report of a patient presenting a metastatic invasive lobular carcinoma in the thyroid and lymph nodes without a prior diagnosis of breast cancer.
