During last many decades, androgen deprivation therapy (ADT) was the main treatment of choice for metastatic castration-naïve prostate cancer (mCNPC). However, there are now more possible treatment options for mCNPC. In CHAARTED, GETUG-AFU 15, and STAMPEDE trial, docetaxel added to ADT improved overall survival compared to ADT alone in mCNPC. Also, STAMPEDE and LATITUDE trial revealed that abiraterone added to ADT improved overall survival compared to ADT alone for mCNPC patient. Furthermore, ARCHES and ENZAMET trial showed that enzalutamide added to ADT also can be a treatment option for mCNPC. Apalutamide added to ADT also improved survival compared to ADT alone in castration resistant prostate cancer patient. The usefulness of radiation therapy to primary tumor in mCNPC has also been studied in HORRAD and STAMPEDE trial. There are many ongoing trials for mCNPC setting. The aim of this paper is to review the current status of mCNPC management options.

벤치마킹은 기업의 경쟁력 향상 및 경영전략수립을 위한 효과적인 도구이나 대상과 방법이 적절치 못한 경우 그 실효성이 저하될 수 있다. 건설업의 경우 제조업과는 생산과 경영구조 그리고 수익구조 등 여러 가지 측면에서 다르기 때문에 다른 방식의 벤치마킹이 필요하다. 국내 건설업의 특성은 동일 유형의 경쟁기업이 다수 존재하고 법규 및 정책 등 외부환경변화에 영향을 많이 받는 등 다양하다. 따라서 건설기업의 벤치마킹은 특성상 기업군을 대상으로 하는 것이 효율적이며 자료수집 시자기업의 성과인 내부자료와 벤치마킹 대상의 성과인 기업자료 뿐 아니라 외부환경변화자료도 수집되어야 하며 기업 간 성과 비교 시 외부환경변화가 반드시 고려되어야 한다. 건설업 특성상 건설기업은 차입금과 자기자본 비율의 변화가 크기 때문에 최적자본구조에 대한 분석도 필요하다. 본 연구는 이와 같은 건설업 특성과 국내 기업의 상황을 분석하여 기존의 벤치마킹 프로세스와 차별된 건설기업 벤치마킹 프로세스를 제안한다. Benchmarking is an effective tool supporting improvement of corporate competitiveness and development of management strategy, however, its effectiveness may be compromised if its target and approach are not appropriate. Notably, the construction industry of Korea is unique in that it has a number of competitors sharing the same category and is significantly exposed to changes in external environment in terms of legal, regulatory and policy frameworks. Such characteristics make target corporate category rather than single company more suitable as benchmarking target and necessitate analysis of external environment. This study intends to analyze the characteristics of construction industry in Korea and conditions of domestic companies in order to propose a benchmarking process for construction industry differentiated from conventional ones.학교 건축공학과, 산학협력기술연구원;경희대학교 대학원;경희대학교 대학원;

Papillary renal cell carcinomas (RCCs) can be classified into 2 subtypes (types 1 and 2), depending on their characteristic cytogenetics, immunostaining profiles, and gene-expression profiles. Compared with type 1 papillary RCCs, type 2 papillary RCCs are relatively rare and show more aggressive features. For those reasons, they are associated with a worse prognosis. A 13-year-old patient was admitted to the hospital with right kidney mass. A laparoscopic radical nephrectomy was performed, and results of the histopathologic examination confirmed it to be type 2 papillary RCC. Type 2 papillary RCCs are rarely found in unilateral and multifocal forms, especially in adolescence. Here, we report the unique case of papillary RCC at a young age.
