The aim of this study is investigate the research trends by analyzing the researches related to Korean and international genetics in oncology nursing. We conducted a text network analysis focusing on the key words presented in the abstracts of papers published in journals related to genetics in oncology nursing. Nurse, Cancer, Genetic, Patient, Knowledge, Care, and Genetic Test were identified as keywords and centralized keywords. As a result of studying research trends over time, researches including keywords such as information, care, and knowledge have increased since the completion of the Human Genome Project in 2003. Key words classified through the meta paradigm of nursing were health, nursing, human, environment order. This study is meaningful in that it can be used to identify trends in tumor genetic nursing research and to set the direction of development of nursing intervention for hereditary cancer patients.

Colorectal cancer is one of the most steeply increasing malignancies in Korea. Among 398,824 new patients recorded by the Korea Central Cancer Registry between 2003 and 2005, 47,915 cases involved colorectal cancers, accounting for 12.0 % of all malignancies. In 2002, total number of colorectal cancer cases had accounted for 11.2 % of all malignancies. Hereditary syndromes are the source of approximately 5% to 15% of overall colorectal cancer cases. Hereditary colorectal cancers are divided into two types: hereditary nonpolyposis colorectal cancer (HNPCC), and cancers associated with hereditary colorectal polyposis, including familial adenomatous polyposis (FAP), Peutz-Jeghers syndrome, juvenile polyposis, and the recently reported hMutYH (MYH)-associated polyposis (MAP). Hereditary colorectal cancers have unique clinical features distinct from sporadic cancer because these are due to germline mutations of the causative genes; (i) early age-of-onset of cancer, (ii) frequent association with synchronous or metachronous tumors, (iii) frequent association with extracolonic manifestations. The management strategy for patients with hereditary colorectal cancer is quite different from that for sporadic cancer. Furthermore, screening, genetic counseling, and surveillance for at-risk familial member are also important. A well-organized registry can plays a central role in the surveillance and management of families affected by hereditary colorectal cancers. Here, we discuss each type of hereditary colorectal cancer, focusing on the clinical and genetic characteristics, management, genetic screening, and surveillance.

Osteochomdromas, which are uncommon in the hand, are encountered most frequently with hereditary multiple exostosis. They can occur away from the epiphyseal plate region at the distal end of the proximal and middle phalanges. But little has been written about exostosis that occur at the distal end of the distal phalnges. We report one case of hereditary multiple exostosis that arose at the distal end of the distal phalnges. Complete excision was done and the patient was disease-free of 4 years follow-up.

Li-Fraumeni syndrome (LFS) is an autosomal dominant hereditary disorder characterised by a variety of different tumor types in children and young adults. That contains with a germline mutation in the tumor suppressor gene Tumor Protein p53 (TP53). That is extremely rare. Furthermore, this is sometimes overlooked. Here, we report a case of LFS which was confirmed by mutational analysis of the p53 gene. Also, literature review is intended to improve understanding of this disease entity.

Werner's syndrome is a rare autosomal recessive disorder manifesting as premature aging. It is also known to be characterized by a high frequency of malignant tumors, especially sarcomas. However, Werner's syndrome may be not only a premature aging disease but also a cancer syndrome, because the malignant tumors in these patients are different from those of normal population with respect to involved site, histological type, and age of onset. Recent studies found Werner's syndrome was caused by a mutation of Werner helicase suggesting that WRN helicase may participate in metabolism and repair of DNA. And a dysfunction of WRN helicase may induce the genomic instability causing somatic mutations. Further studies of Werner's syndrome associated with sarcoma might give much informations about the normal aging process and the pathogenesis of sarcomas.

In this paper, dielectric characteristics of pathological tissues cultivated using the xenograft method were analyzed. Since cancerous tissues were extracted from the nude mouse just before the measurements, they were maintained as fresh as living tissues in the measurements. This would be one of the advantages to get more accurate and reliable results. Dielectric properties of four cancerous tissues such as brain cancer, breast cancer, colon cancer and gastric carcinoma were measured in the frequency range between 45 MHz and 5 GHz. For the measurement of the dielectric properties, 58 xenografted samples were used. It was found that all of the cancerous tissues had the similar dielectric constant values. Comparing with the normal tissues, dielectric constant values of brain cancer, breast cancer and colon cancer were higher than those of the normal tissues except gastric carcinoma in the frequency range.

Purpose: This study was performed to evaluate Korean nurses' knowledge about hereditary colorectal cancer (HCRC). Methods: A modified 15-item HCRC knowledge questionnaire was developed based on previous research. One hundred and forty-eight nurses have completed the questionnaire from February to April, 2011. Results: The average score of nurses' knowledge was $11.25{\pm}1.54$. Ninety-seven percent of nurses knew about colonoscopy check up schedule and family pedigree. However, only 20% of nurses knew about the rate of passing on mutation genes to offspring and risk of developing CRC among carriers. Only 13.5% of nurses had previous genetic education experiences. Working in oncology units, taking care of CRC patients, and participating in genetic education were not associated with nurses' HCRC knowledge. Conclusion: Various factors influence nurses' knowledge about HCRC. Repeated study with larger national sample of nurses is recommended to identify the factors affecting nurses' knowledge level in order to develop efficient genetic education programs for HCRC patients and their families by nurses.

Purpose: This study was aimed to analyze the incidence and the anatomical distributions of HME (Hereditary Multiple Exostoses) on upper limbs and its related change in alignment of the upper limbs in HME patients. Materials and Methods: Thirty eight patients who had been diagnosed HME between 2001 and 2009, were categorized into two groups; (1) group A (1-2 involvements); (2) group B (${\geq}$3 involvements). We checked the carrying angle, VAS (Visual Analogue Scale), limitations in daily activities, cosmetic satisfaction according to the number of exostoses invasion. Results: Among the 38 patients, 23 patients (43 cases) had exostoses in the upper limbs. The locations of exostoses in the upper limbs were proximal humerus in 33 cases (30%), distal ulna in 31 cases (28.2%), and distal radius in 24 cases (21.8%). The carrying angle of group A and B was $10.7^{\circ}$, $13.8^{\circ}$, VAS was 1.3, 3.5, and the limitations in daily activities was 7.3, 6.6 of 8 points. The cosmetic satisfactory cases were 13 and 10 cases, respectively. Conclusion: The deformity in upper limbs was observed in 65% of the HME patients. As the number of invasion increases, carrying angle and VAS were increased but limitations in daily activities and cosmetic satisfaction were decreased.

이식 전 수정란의 성판정은 많은 축산인의 소망이었다. 많은 방법이 제기되었지만, 세포유전학적 분석방법은 ET의 상용화에 거의 무의미할 정도로 한계가 많았고, 이후 개발된 응성 특이적 항원이나 X-염색체에서 발현되는 효소의 활동을 통한 성판정 방법은 흥미롭기는 하나 산업적 적용에 제약이 많았다. 80년대 중반 Y-염색체 특이적인 DNA 탐침자의 개발과 PCR을 통한 DNA증폭기술의 개발은 수정란 성판정을 획기적으로 개선시켰다. DNA기술을 통한 수정란의 성판정은 분자생물학을 현장으로 진출시킨 첫 경우이기도 했다. 90년대에 세포유전학적 분석에서 FISH가 소개되었으며, 염색체 특이적 library는 다른 기초적이고 응용세포유전학적 연구에 유용한 도구가 되었다. 최근에는 사람에서는 착상전 수정란의 성판별 및 유전진단을 위해 실시되고 있는 형광직접접합법(fluorescent in situ hybridization, FISH)은 효소적 유전자 증폭(polymerase chain reaction; PCR)에 비해 높은 민감도와 정확성을 보이고 있으나 hybridization 및 washing 과정에 매우 긴 시간이 소요되고, 절차도 까다로워 현장에서의 적용이 용이치 않았다. 그러나 direct labelled probe의 이용, heat programmable instrument의 개발, denaturing chemical의 사용배제 등을 통해 소요시간 및 절차의 대폭적인 간소화를 이루어 현장의 적용 가능성을 한층 높이고 있다. 현재 사람의 세포유전학 및 종양학에서는 FISH의 다양한 기술이 많이 이용하고 있으나 소에서는 탐침자(probe)가 개발되어 있지 않아 그 이용이 미미하다. 본 연구는 FISH를 이용하기 위한 탐침자의 개발을 궁극적인 목표로 삼았으며, 이를 위해 접근이 용이한 방식을 개발하여 기존의 방식과는 다른 소 배아세포의 성을 판별 할 수 있는 접근방법을 소개 하고자한다.

The melanotic neuroectodermal tumor of infancy(MNTI) is a rare childhood neoplasm with a clinical presentation. Because of its rapid growth pattern and bone resorption, the lesion can be mistaken for a malignant neoplasm. Although an aggressive growth rate and radiographic appearance, the MNTI almost always behaves in a benign fashion and can be treated with total excision. We presented the MNTI occured in the left maxillary alveolar ridge of 5 month old female infant. showing bluish enlargenent of alveolar mucosa with the displacement of central decidious incisor. And after the surgical excision of the mass, there is no recurrent tendency.
