There are approximately 1,000 patients who undergo mastectomies each year in Korea. However, there is no company who manufactures mastectomy brassieres and breast prosthesis in Korea. The purpose of this study is to evaluate the wearing conditions of the imported mastectomy brassieres with breast prosthesis and to develop the better-fitted and comfortable mastectomy brassieres in reasonable price. 254 patients participated in this survey. In the results of our survey, 117 out of the 254 patients were wearing mastectomy brassieres and breast prostheses, which have been imported mostly from USA. The degree of satisfaction at wearing mastectomy brassieres was low. The patients generally feel hot when wearing mastectomy brassieres, specially in summer and also pointed out the heavy weight of breast prosthesis and the discomfort in wearing mastectomy brassiere for a long period of time.

This study proposes an algorithm for predicting breast cancer prognosis based on genetic network. We identify prognosis-specific network using gene expression data and PPI(protein-protein interaction) data. To acquire the network, we calculate Pearson's correlation coefficient(PCC) between genes in all PPI pairs using gene expression data. We develop a prediction model for breast cancer patients with estrogen-receptor-negative using the network as a classifier. We compare classification performance of our algorithm with existing algorithms on independent data and shows our algorithm is improved. In addition, we make an functionality analysis on the genes in the prognosis-specific network using GO(Gene Ontology) enrichment validation.

This study was to investigate the effects of joint mobilization with two different electrotherapy methods on shoulder external rotation range of motion and pain in mastectomy patients. Thirty mastectomy patients were divided into STMG (joint mobilization+pain scrambler therapy, n=15) and TENMG (joint mobilization+transcutaneous electrical nerve stimulation, n=15). The measurements were performed shoulder external rotation range of motion (ROM), pain (VAS). In both groups, there was a significant difference in the shoulder external rotation ROM, pain after intervention (p <.05). STMG was more decrease in VAS score than TENMG (p <.05). There was no significant difference in shoulder external rotation ROM between the two groups. In order to decrease the pain of mastectomy patients, it was confirmed that STMG was more effective than TENMG.. It is thought that a control group is added to confirm various differences, and more subjects are needed.

Little is known about roles of adipose tissue, although obesity is one of the potential risk factors in causing breast cancer and adipose tissue surrounding breast ductal cells is the largest organ. To identify the genes that are regulated by factors secreted from adipocytes in breast cancer cells, MDA-MB-231 cells were treated with the culture medium of adipocytes. In present study glucocorticoid-induced TNF receptor-related protein ligand (GITRL) gene was studied among the induced genes. It was found that GITRL was significantly increased by the culture medium of adipocytes. Proteinase K-treated adipocyte culture supernatants failed to induce GITRL expression. These findings indicate that unknown protein factors are responsible for the induction of GITRL expression. The expression of GITRL did not affect the invasive ability of MDA-MB-231 cells, but coculture with NK92 expressing GITR suppressed the invasiveness of MDA-MB-231 cells.

본 연구는 전국 6개 광역시 및 각 도별로 우리 나라 주요 암의 지역적 분포 현황을 살펴보고 그러한 지역차의 원인을 규명해 보고자 한다. 전국 시 도별 암 등록 현황 자료를 토대로 위암, 직장.결장암, 간암, 폐암과 유방암의 전체 암에 대한 시 도별 상대적 위험도를 분석하여 지리정보체계(GIS)를 이용한 지도화를 근간으로 분석하였다. 위암의 경우 위암 발생의 상대적 위험도는 해당 지역 병원이 부담해야 하는 인구수와 관련성이 있는 것으로 보여졌다. 또한, 폐암의 경우도 대도시지역이 상대적으로 낮은 발병율을 보였으며, 농촌지역은 폐암의 고위험지역으로 나타났다. 이러한 폐암 환자의 분포 현황은 도시 지역에 비해서 농촌 지역의 흡연율이 높은 것과 밀접한 관련성이 있는 것으로 보인다. 직장.결장암의 상대적인 위험도도 도시지역보다는 농촌지역에서 높았다. 이러한 분포 패턴은 농촌지역의 노령화 현상과 관계가 있는 것으로 보인다. 그렇지만, 유방암의 경우 농촌지역보다 대도시지역에서 높은 발암율을 보였다. 이것은 유방암 발생이 식생활을 포함하는 서구화된 생활방식과 관련성이 있음을 시사해 주는 것이다. 간암은 부산, 경남 및 전남 지역에서 높은 환자 빈도를 나타냈다. 특히, 이 해안지역에서의 간암의 상대적으로 높은 위험성은 ‘회’의 섭취로 인한 감염성 질환과 관련이 있는 것으로 보인다.

Purpose : To evaluate the MRI findings of breast cancer with BRCA mutation. Materials and Methods: We collected information of the breast cancer patients who underwent the test for BRCA gene mutation as well as preoperative breast MRI from January 2007 to December 2010. A total of 185 patients were enrolled; 33 of these patients had BRCA mutations and 152 patients did not. Among them, a total of 231 breast cancers were detected. Images of the 47 breast cancers with BRCA mutation and of the 184 breast cancers without mutations were evaluated to compare the morphologic and enhancement features on MRI. Results: With MR imaging, there were no significant difference in morphologic characteristic between two groups. However, enhancement pattern in the group with BRCA mutation were more likely to have persistent enhancement (p < 0.233), and LN metastasis was more common in breast cancers without BRCA mutation. Breast cancers with BRCA 2 mutation tend to show more persistent enhancement pattern than BRCA 1 mutation. Conclusion: In breast cancer patients with BRCA mutation, MRI didn't show significant difference in morphologic characteristics, however breast cancers with BRCA gene mutation carriers tend to have benign morphologic features on MRI, such as Type 1 kinetic curve enhancement.

세계에서 매년 약 1,000만명의 새로운 암환자가 발생하고 있으며, 650만명이 암으로 사망하고 있다. 우리나라에서도 매년 약 85,000명의 새로운 암환자가 등록되고 있으며, 55,000명이 암으로 사망하고 있다. 이는 우리나라 전체 사망자의 20%를 차지하는 수치로서 사망원인으로는 단연 1위에 해당한다. 이처럼 암 발생과 암으로 인한 사망이 급격하게 증가함에 따라 암을 일으키는 원인인자를 밝히고 이러한 원인을 제거하여 암을 예방하려는 노력들이 활발하게 이루어지고 있다. 실제로 몇몇 암의 경우에는 그 발생 원인들이 일부 밝혀지고 있는데, 대표적으로 금연을 통하여 폐암의 발생을 예방하고 간염백신 접종을 통해 간암을 예방하는 경우 등이다. 한편, 세계보건기구에서는 의학적인 관점에서 암 발생인구 가운데 1/3은 예방가능하고, 1/3은 조기진단만 되면 완치가 가능하며, 나머지 1/3의 환자도 적절한 치료를 한다면 완치가 가능한 것으로 보고하고 있다. 특히 우리나라에서 가장 흔한 위암, 유방암, 자궁경부암, 대장암 등은 조기에 발견할 경우 거의 완치가 가능하기 때문에, 이러한 암들에 대해서 정기적으로 검진을 실시할 겨우 암으로 인한 사망을 상당수 줄일 수 있을 것으로 기대된다. 이에 정부는 2002년부터 저소득층을 대상으로 위암, 유방암, 자궁경부암에 대해 조기검진을 무료로 실시하고 있으며, 암 예방 교육 및 홍보를 통하여 국민들에게 암에 대한 정확한 지식과 조기검진의 중요성을 전달하고, 나아가 생활양식의 변화를 유도하여 암을 예방하도록 하는 마스터플랜을 추진하고 있다.

Breast cancer is the leading cause of cancer death in women worldwide and the number of women breast cancer patient was increased continuously. Most of breast cancer patient has suffered from unnecessary radiation exposure to heart, lung. Low radiation dose to the heart could lead to the worsening of preexisting cardiovascular lesions caused by radiation induced pneumonitis. Also, several statistical reports demonstrated that left-sided breast cancer patient showed higher mortality than right-sided breast cancer patient because of heart disease. In radiation therapy, Deep Inspiration Breath Hold (DIBH) technique which the patient takes a deep inspiration and holds during treatment and could move the heart away from the chest wall and lung, has showed to lead to reduction in cardiac volume and to minimize the unnecessary radiation exposure to heart during treatment. In this study, we investigated the displacement of heart using DIBH CT data compared to free-breathing (FB) CT data and radiation exposure to heart. Treatment planning was performed on the computed tomography (CT) datasets of 10 patients who had received lumpectomy treatments. Heart, lung and both breasts were outlined. The prescribed dose was 50 Gy divided into 28 fractions. The dose distributions in all the plans were required to fulfill the International Commission on Radiation Units and Measurement specifications that include 100% coverage of the CTV with ${\geq}95%$ of the prescribed dose and that the volume inside the CTV receiving >107% of the prescribed dose should be minimized. Scar boost irradiation was not performed in this study. Displacement of heart was measured by calculating the distance between center of heart and left breast. For the evaluation of radiation dose to heart, minimum, maximum and mean dose to heart were calculated. The present study demonstrates that cardiac dose during left-sided breast radiotherapy can be reduced by applying DIBH breathing control technique.
