Objectives : Purpose of this study was to investigate physiological and neurocognitive effects of total sleep deprivation by using laboratory blood tests and the computerized neurocognitive function test in healthy subjects. Methods : Sixteen healthy volunteers participated in this study. Subjects were recommended to remain awake for 48 hour sunder continuous surveillance. Lab tests of cortisol, Prolactin, thyroid hormone, growth hormone, and immunoglobulin (IgG, IgA, IgM, IgD, IgE), CBC, BC and the Vienna test were performed before and after 48 hours of total sleep deprivation. Results : Concentration of T3 and T4 significantly increased after deprivation. In the reaction test, distribution reaction time significantly increased, and correct reaction significantly decreased. In the vigilance test, amount of correct reaction Signifi-cantly decreased, and the mean value of correct reaction time was significantly delayed. Level of fasting blood sugar, total protein, albumin, alkaline phosphatase and potassium significantly increased, respectively, except for the level of total bilirubin which was decreased. After total sleep deprivation, WBC counts significantly increased. Regarding immunoglobulin level, IgG,IgA and Ag M concentrations appeared to decrease, but the results were not statistically significant. Conclusion : The effect of total sleep deprivation on physiological function was significant in the level of thyroid hormone. Although statistically not significant, the results of growth hormone and the immune system showed a trend in relations to the effect oftotal sleep deprivation. Results of blood chemistry suggest that sleep dephvation may influence metabolism Of hepato-biliary system. Cognitive impairment was also seen in reactive and vigilant functions after total sleep deprivation.

이후경,김선재,차정화,봉수연,안현주 대한신경정신의학회 2000 신경정신의학 Vol.39 No.2

연구목적: 집단정신치료는 또래집단을 중요시하는 품행장애 청소년의 치료로서 매우 효과적인 것으로 알려져 있으나 한국에서는 아직 활성화되지 못하고 있다. 이에 따라 저자들은 품행장애 청소년에게 효과적으로 적용될 수 있는 폐쇄형, 동질적인, 시간제한(10회), 외래집단정신치료를 주 1회 실시하였다. 본 연구의 목적은 ①품행장애 청소년을 대상으로 집단정신치료를 시행하여 효과성을 평가하고, ②치료요인을 조사하여, ③ 집단정신치료를 품행장애 청소년에게 효과적이면서 효율적으로 적용될 수 있는 치료방법으로 정착시키는 데 있다. 대상 및방법: 본 연구는 1998년 10월붜 12월까지, 1999년 4월부터 6월까지 두차례에 걸쳐 실시하였다. 대상군은 품행장애 범주에 해당하는 H고교 2학년 여학생 총 18명(4명 도중 탈락), 대조군은 같은 범주에 해당하는 H고교 2학년 여학생 중 치료에 참여하지 않은 총 18명(4명 도중 탈락)이었다. 평가도구로는 프로그램 실시 전후에 자기보고식 비행척도, 공격성척도, 충동성척도을 시행하였고, 매 회기가 끝난 직후 Yalom의 13가지 치료요인척도, 집단치료 만족도 설문지를 시행하였으며, 종결모임시 총평가 설문지를 시행하였다. 결과: 치료요인의 변화를 집단발단단계에 따라 전후반기로 나누어 비교하였을 때, 전반기(1∼5회)에 상위를 차지한 치료요인은 순서대로 실존적인자, 보편성, 카타르시스, 리더와의 동일시, 구성원과의 동일시이었으며, 후반기(6∼10회)에 상위를 차지한 치료요인은 카타르시스, 실존적인자, 리더와의 동일시, 구성원과의 동일시, 구성원의 조언이었다. 전반기에 비해 후반기에 상대적으로 카타르시스, 구성원의 조언이 상승하였고 보편성은 하락하였다. 이타주의와 일차가족집단의 교정적 반복발달은 전후반기 모두 최하위를 기록하였다. 집단치료 만족도 설문에서 전반기는 45.7%, 후반기에는 83.3%가 도움받는 것으로 나타났고, 총평가 설문에서 85.7%가 기회가 있다면 다음에도 참여하고 싶다고 보고하였다. 결론: 시간제한 외래집단정신치료가 품행장애 청소년 에게 적용할 때 매우 효과적이면서도 만족도가 높은 것으로 나타났다. 청소년을 대상으로 외래집단정신치료를 시행하는 것은 구성상의 어려움, 동기부족, 기금부족 등, 여러 제반 문제가 있으나 확대 시행되어야 할 것으로 생각된다. Objectives: Group psychotherapy is known to be an dffective treatment program for adolescents who attach importance to peer relationship, but it is not activated in Korea. Therefore, researchers performed weekly the closed, homogeneous, time-limited(10 sessions), outpatient group psychotherapy for adolescents with conduct disorder. Objectives of this study were as follows ; first, we practiced the group psychotherapy for adolescents with conduct disorder and evaluated its effectiveness ; second, we examined the therapeutic factors which were used by participants ; third, we intended to settlee down the group psychotherapy for adolescents with CD as an effective and efficient treatment modality. Methods: This study was performed two times from October to December in 1998 and from April to June in 1999. It was sponsored by Youth Counselling Center in H city. The case group were composed of 15 female students who were second grade in H high school, and 4 students were dropped out. The control group were composed of 18 female students who were same grade in H high school and 3 students were dropped out. Before and after this program, self-report delinquency scale, aggression scale and impulsivity scale were asked to them. And just after each session, Yalom 13 therapeutic factors scale and satisfaction questionnaire for group psychotherapy were asked to them. And at last meeting, total assessment questionnaire was asked to them. Results: We compared the change of therapeutic factors between the former half sessions (1-5) and the later half session(6-10), and the results were as follows ; in the former half, the upper ranks of therapeutic factors were existential factor, universality, catharsis, identi- fication with leader, and identification with members in order. And in the later half, the upper ranks of therapeutic factors were catharsis, existential factor, identification with leader, identi - fication with members, and guidance of members in order. The rank of catharsis and guidance of members went upward and the rank of universality went downward when we compared the ranks in the former half to those in the later half. Altruism and family enactment were the lowest ranked in both half. The satisfaction questionnair for group psychotherapy showed to be helped by participants at the rate of 45.7% in former half, 83.3% in later half. The total assessment questionnaire showed the willingness of re-participation at the rate of 85.7% if future opportunity of group psychotherapy is given for them. Conclusions: The time-limited group psychotherapy for adolescents diagnosed by conduct disorder was very effectively practiced and the participants reported high level of the satisfaction. The outpatient group psychotherapy for adolescents would be expanded and practiced though there are several accompanied problems including the difficulty of structuring, the deficit of motivation, and financial problem.

외래환자를 위한 시간제한 집단정신치료

이후경,차정화,윤성철,김정일 大韓神經精神醫學會 2001 신경정신의학 Vol.40 No.3

연구목적 : 최근 외래집단정신치료는 전통적인 장기치료에서 단기치료나 시간제한치료로 전환되고 있는 추세다. 단기는 보통 10∼40회 걸쳐 실시되는 것에 비해 시간제한(time-limited)은 시작부터 종결시기 및 횟수를 미리 정해놓고 실시한다. 이는 치료자와 환자간에 가능성 있는 구체적인 치료목표를 설정하고 적극적인 공동작업을 통하여 정해진 기간에 효과적인 치료결과를 가져올 수 있기 때문에 효율적인 치료방법으로 점차 부상되는 있는 양식이다. 본 논문의 연구목표는 다음과 같다 ① 정신과의원 외래환자를 대상으로 시간제한 집단정신치료를 시행하여 치료효과와 치료요인을 조사한다. ② 집단정신치료 시행과정에 나타나는 특징을 살펴본다. ③ 본 집단정신치료의 적절성과 타당성을 검증하여, 현재 한국 의료상황에 맞는 저비용, 고효율적인 모델로서 정착시켜 외래치료를 보다 효과적으로 할 수 있는 기반을 마련하다. 방 법 : 본 연구는 2000년 4월부터 동년 7월까지 매주 1회, 한번에 70∼80분씩, 총 12회 걸쳐 실시되었다. 실험군은 정신과의원 외래환자중 기능수준이 높은 정신병환자를 대상으로 하였다. 대조군은 비슷한 나이, 성별, 진단군, 유병기간을 일대일 짝을 지어 선정하였다. 각각8명이 참여하였다. 평가도구는 BDI, STAI,MMPI, 이화방어기제를 사전, 사후에 실시하였고, 매회 마다 13가지 치료요인 척도를 실시하였으며, 총평가 설문지를 마지막에 실시하였다. 결 과 : BDI는 실험군에서 대조군에 비하여 유의미하게 감소하였다. STAI-S는 실험군, 대조군 모두에서 차이가 없었고, STAI-T는 실험군에서 대조군에 비하여 유의미하게 감소하였다. MMPI는 실험군에서 대조군에 비하여 통계적으로 유의미하게 감소하였지만, 사전-사후 변화량에 대한 집단간 검사에서 유의미하지 않았다. 이는 두 군에 동일하게 노출된 약물치료와 지지치료의 영향으로 추측된다. 이화방어기제는 실험군에서만 미성숙 방어기제와 신경증적 방어기제의 유의미한 감소를 보였다. 치료요인은 초기, 중기, 말기로 나누어 비교했을 때, 전 회기에 걸쳐 실존적 인자가 1위를 차지하였고, 카타르시스, 치료자동일시, 보편성, 집단응집력이 내내 상위를 차지하였다. 초기, 중기에 중하위를 차지하였던 대인관계학습은 말기에 2위를 기록하였다. 총평가 설문에서 참여자의 100%에서 도움 받은 것으로 보고하였고, 75%에서 생활의 변화를 보고하였으며, 75%에서 재참여 의사를 밝혔다. 결 론 : 외래환자들에게 단순히 약물치료와 지지치료만을 시행하는 것에 덧붙여 시간제한 집단정신치료를 시행할 때 증상호전뿐만 아니라 성격변화의 효과도 가져오는 것으로 나타났다. 또한 참여자들의 집단정신치료에 대한 만족도도 매우 높은 것으로 나타났다. 집단정신치료는 정신치료에 뿌리를 두면서 이에 필적하는 치료효과가 있는 것으로 공인된 치료양식이다. 의약분업 및 의료비 감축 등의 급변하는 현 의료환경에서 집단정신치료와 시간제한치료가 정신치료와 장기치료만큼 효과 있으면서 저비용, 고효율적인 양식으로서 정착될 수 있을 것이다. Objectives : Recently, the outpatient group psychotherapy has been changed from traditional long-term therapy to short-term or time-limited therapy. The termination time and session numbers are given from start line in the time-limited therapy while 10 to 40 sessions are needed in the short-term therapy. And therapist and patients come to an agreement of the accomplishable therapeutic goal and work together actively. The time-limited group psychotherapy is being accepted newly as an efficient therapeutic modality because effective therapeutic outcomes within given time have been reported. The objectives of this study are as follows ; firstly, we examine the therapeutic outcomes and the therapeutic factors after performing the time-limited group psychotherapy for outpatients in the psychiatric clinic ; secondly, we analyze the characteristics showed in the process of study ; lastly, we verify the feasibility and the validity of this group psychotherapy and then establish the basis of the effective outpatient therapy that would be settled down as an applicable treatment modality economically and efficiently in the current medical environment of Korea. Methods : This study was performed weekly in total 12 sessions from July 1999, April 2000 to and each session took 70-80 minutes. The experimental group were composed of the highly-functioning psychotic patients among outpatients in the psychiatric clinic. The control group were composed of the similar patients through one-to-one matching of age, sex, diagnosis, and duration of illness. The participants were 8 patients each. BDI(Beck Depression Inventory), STAI(Spielbergs State-Trait Anxiety Inventory), MMPI(Minnesota Multiphasic Personality Inventory), and EDMT(Ewha Defence Mechanism Test)as the evaluation scales were performed before and after treatment. And 13-therapeutic factors scale was performed just after each session and the self-report total assessment questionnaire was performed only in experimental group at the end of this study. Results : The mean score of BDI was decreased significantly in experimental group in comparison with control group. The mean score of STAI-S was not changed significantly in both group, and the mean score of STAI-T was decreased in experimental group in comparison with control group. The mean score of MMPI was decreased significantly in experimental group in comparison with control group, but the comparison of difference scores(post-treatment score-pre-treatment score) between the experimental and control group was not decreased significantly. This result may come from psychopharmacotherapy and individual supportive psychotherapy given equally to both group. The mean scores of immature defence and neurotic defence in EDMT were decreased significantly in experimental group compared with control group. Comparing the therapeutic factors to divide into the first, middle, and the last stage, existential factor was ranked first, and catharsis, identification with therapist, universality, and group cohesiveness were ranked high in all stages. Interpersonal learning was ranked first in the last stage altinough being ranked low in the first and middle stage. The total assessment questionnaires about group psychotherapy were reported that 100% of participants were helped, 75% of participants were changed in their lives, and 75% of participants had minds to join this kind of program again if given for them. Conclusions : This result shows that not only symptom relief but also personality change was achieved when the time-limited group psychotherapy was practiced in addition to simple psychophamarcotherapy and individual supportive psychotherapy for outpatients. The degree of satisfaction for group psychotherapy of participants were evaluated highly. Group psychotherapy has been accepted in public as therapeutic modality that must be as equally effective as psychotherapy although group psychotherapy derives from individual psychotherapy. In out current medical environment that has been changed suddenly by the separation of medical practice and pharmaceutical dispensing and the decrease of medical fee, group psychotherapy or time-limited therapy would be settled down as low-expense and high-efficiency therapeutic modalities that were as equally effective as individual psychotherapy or long-term therapy

정신병환자에서 집단정신치료와 싸이코드라마의 치료요인 비교

윤성철,이후경,정인과,이규항,함 웅,차정화 大韓神經精神醫學會 1998 신경정신의학 Vol.37 No.3

목 적 : 본 연구에서는 정신병환자를 대상으로 실시한 집단정신치료와 싸이코드라마에 작용하는 치료요인을 조사하여, 그 치료적 특성들을 비교하기 위한 목적으로 이루어졌다. 방 법 : 1996년 9월부터 1997년 5월까지 낮병원에 참여한 환자를 대상으로 하였다. 대상자는 총 35명의 정신병환자로 남자 22명, 여자 13명이었다. 동일한 낮병원 환자들에게 집단정신치료와 싸이코 드라마를 각각 시행한 후, 13가지 치료요인 척도를 사용하여 집단정신치료의 구성원, 싸이코드라마의 주인공, 싸이코드라마의 관객에 작용하는 치료요인의 순위를 각각 조사하였다. 이 세 집단을 모두 상위기능 집단과 하위기능집단으로 나누어 치료요인을 비교하였다. 상위와 하위기능집단은 낮 병동에서의 생활, 치료 프로그램에 참여하였을 때의 태도, 치료자와 면담하였을 때의 모습을 기준으로 하여 낮병원 치료팀 모임에서 치료자들의 합의에 의해 결정하였다. 각각의 치료 요인은 평균점수를 산출하여 치료 요인의 순위를 매겼으며, 이 순위에 의해 집단정신치료, 싸이코드라마의 주인공, 싸이코드라마의 관객에 작용하는 치료요인의 특징을 비교하였다. 결 과 : 본 연구에서 나타난 치료요인에 대한 특정적인 결과는 다음과 같다. 1) 싸이코드라마에서 주인공은 기능수준에 관계없이 모두 “카타르시스”와 “일차 가족 집단의 교정적 감정 경험”을 매우 중시하였다. 2) 싸이코드라마에서 주인공은 상위기능집단의 경우 “치료자의 조언”을 하위기능집단의 경우 “구성원의 조언”을 중시하였다. 3) 싸이코드라마에서 관객은 기능수준에 관계없이 모두 “치료자와의 동일시” 와 “구성원과의 동일시”를 매우 중시하였으며, 또한 보편성을 중시하였다. 4) 상위기능집단의 경우 집단정신치료 싸이코드라마의 관객 및 주인공에서 “대인관계학습”을 중시하였으며, 특히 집단정신치료에서 “대인관계학습”을 매우 중시하였다. 5) 하위기능집단에서 싸이코드라마의 주인공과 집단정신치료에서 모두 “사회화 기술의 발달”을 중시하였다. 결 론 : 본 연구의 결과를 종합하여 다음과 같이 제안할 수 있다. 먼저 집단정신치료나 싸이코드라마를 환자에게 시행할 때 치료자가 치료요인을 고려하여 치료를 진행하는 것이 효과적일 것으로 생각된다. 다음으로 집단정신치료와 싸이코드라마는 모두 동일하게 중요한 치료법으로 실제 임상에서 널리 이용하는 바람직한 것으로 생각된다. 마지막으로 집단정신치료와 싸이코드라마의 기법을 서로 혼합하여 사용한다면 매우 효과적인 치료법이 될 수 있을 것으로 생각된다. Objective : This study was performed to investigate the therapeutic factors of group psychotherapy and psychodrama which were applied to psychotic patients, and to compare the therapeutic characteristics of two therapies. Methods : The subjects of this study were patients of a day hospital from September 1996 to May 1997. The subjects were composed of 35 psychotic patients(22 males, 13 females). Both of group psychotherapy and psychodrama were done to the patients of the day hospital. After these therapeutic factors were checked by the members of group psychotherapy, the protagonists of psychodrama, and the audience of psychodrama using 13 therapeutic factors scale. All three groups divided into higher functioning group and lower functioning group by mutual consent of the therapists in the treatment team meeting according to the patient's life of the day hospital, the attitude in programs, and the state during the interview with the therapist. And then therapeutic factors of higher and lower functioning group were compared. By the mean score of each therapeutic factor the rank of therapeutic factors was decided. By these ranks we compared the important therapeutic factors on the members of group psychotherapy, the protagonists, and the audience. Results : The results were as follows : 1) The protagonists of psychodrama set a very high value on “catharsis” and “the corrective recapitulation of the primary family group”, regardless of their functional level. 2) The protagonists with a higher function set a higher value on “guidance of therapists”, while those who had a lower function set a higher value on “guidance of members”. 3) The audience of psychodrama set a very high value on “identification with therapists”, “identification with members”, and set a high value on “universality”. 4) The higher functioning group of the group psychotherapy, the audience, and the protagonists set a high value on “interpersonal learning”, especially the patients of group psychotherapy set a very high value on “interpersonal learning”. 5) The lower functioning group of the protagonists and the group psychotherapy set a high value on “development of socializing techniques”. Conclusion : From the results of this study, we can draw some suggestions. First, if therapists take the above-mentioned therapeutic factors into consideration during the sessions of group psychotherapy or psychodrama, they can obtain more effective therapeutic outcome. Second, it is desirable that both group psychotherapy and psychodrama should be used more extensively as important methods of treatment in clinical settings. Third, the combination group psychotherapy and psychodrama would be more effective than the separate application of each therapy.

MIN 모듈을 갖는 Hidden Markov Model의 학습 방법에 관한 연구

김대극,이정주,정호균,이상희 강원대학교 정보통신연구소 2001 정보통신논문지 Vol.5 No.-

In this paper, we propose the HMM with the MIN module. Because initial and re-estimated variance vectors are important elements for performance in HMM recognition systems, we propose a method which compensates for the mismatched statistical feature of training and test data. The MIN module is an element of the generalized learning vector quantization (GLVQ) network, which generalizes learning conditions of LVQ and minimizes errors of the cost function given to generate optimized reference vectors. The proposed hybrid HMM/MIN module is a unified network in which the observation probability in the HMM is replaced by the MIN module neural network. Two kinds of experiments were performed to compare the performance of the proposed HMM and the conventional HMM.

조수진,박은애,유은선,김혜순,손세정,서정완,이승주,한후재 이화여자대학교 의과대학 2003 EMJ (Ewha medical journal) Vol.26 No.2

목적: 급성 파종성 뇌척수염은 감염이나 예방 접종 후 발생하는 중추 신경계의 급성 자가 면역 염증성 질환으로 탈수초를 일으킨다. 신경학적인 증상으로 발현되고 대부분 환전히 회복되지만 신경학적 후유증을 남기거나 사망 할 수도 있다. 이에 저자들은 본원에서 발생 한 14명을 분석하여 조기 진단과 치료에 도움을 주고자 하였다. 대상과 방법: 1998년 3월부터 2003년 8월까지 이대목동병원에서 급성 파종성 뇌척수염으로 진단 받은 14명의 의무기록을 후향적으로 조사하였다. 결과: 환자들의 평균 발생 연령은 5±7.8개월이였고, 특정계절이나 연도에 집중되어서 나타나지는 않았다. 선행질환은 주로 비특이적인 상기도 감염이 가장 많았고, 초기증상으로는 경련이 가장 많았다. 그 외에 의식저하나 운동장애도 있었다. 뇌척수액 검사에서 백혈구 증가증이 발견된 경우는 있었으나 단백이 증가된 경우는 없었다. 뇌 자기공명 촬영에서 T2 증강시 뇌백질과 기저핵에 고음영의 다발성 병소가 발견되었고 추적 촬영에서 대부분에서 소실되었다. 뇌파 검사가 시행되었던 경우 전반적인 서파가 가장 많았고 국소적인 극파가 나온 경우도 한 명 있었다. 환자들은 정맥 면역 글로블린과 메틸프레드니졸론으로 치료하였고 치료 시작 후 3~7일내 증상이 호전되었다. 모든 환자를 2달 이상 추적 관찰하였고 항경련제가 지속적으로 필요한 정도의 경련성 질환이 두 명, 신경아교증이 남아잇는 경우가 한 명, 외래에서 다발성 경화증이 의심되는 경우가 한 명 있었다. 결론: 급성 파종성 뇌척수염은 침범 부위에 따라서 다양한 임상 상으로 나타나며 면역 글로블린과 메틸프레드니졸론이 치료에 효과적이였다. 본 연구에서는 대상 환자수가 적어 신경학적 후유증의 위험요소는 밝힐 수는 없으나, 예후는 검사소견과 연관되어 있지는 않았고, 대부분에서 양호하여 완전히 회복되었으나, 신경학적 후유증이 남은 경우도 있었다. Objective:Acute disseminated encephalomyelitis(ADEM) is an acute demyelinating autoimmune inflammatory disease of the central nervous system which develops after infection of vaccination. It may be fatal, and produce a permanent residual static disability or fully recover. We retrospec-tively studied 14 cases to investigate the clinical findings and outcome of ADEM. Methods : 14cases of ADEM diagnosed at Ewha Womans University Mokdong Hospital from 1998 to 2003 were retrospectively reviewed. Results : The age of onset was 5years±7.8 months and no seasonal clustering was found. The time of onset of symptoms was between 3 to 30 days. The preceding events were nonspecific upper respiratory infections in 9 cases, aseptic meningitis in 4 cases, and gastroenteritis in one case..The initial symptoms were seizure, altered consciousness, hemiparesis, fever, headache, and vomiting. Brain MRI showed multifocal high signal intensity lesions on T2 weighted image mainly in the cerebral whith matter, basal ganglia and periventricular white matter. EEG was performed in some cases and showed generalized or focal slow waves and only one case showed focal spikes. Patients were treated with IV globulin and methylprednisolone and the symptoms improved within 3-7 days after treatment. All patients were followed up for more than 2 months and most of them fully recovered except two. Conclusion : ADEM presents in various clinical manifestations depending on its involvement of the brain lesions. Most cases recovered fully but in some cases, residual permanent neurologic sequelae remained.

Lee, Sea-Won,Hwang, Tae-Kon,Hong, Sung-Hoo,Lee, Ji-Youl,Chung, Mi Joo,Jeong, Song Mi,Kim, Sung Hwan,Lee, Jong Hoon,Jang, Hong Seok,Yoon, Sei Chul The Korean Society for Radiation Oncology 2014 Radiation Oncology Journal Vol.32 No.3

Purpose: This single institutional study is aimed to observe the outcome of patients who received postoperative radiotherapy after radical prostatectomy. Materials and Methods: A total of 59 men with histologically identified prostate adenocarcinoma who had received postoperative radiation after radical prostatectomy from August 2005 to July 2011 in Seoul St. Mary's Hospital of the Catholic University of Korea, was included. They received 45-50 Gy to the pelvis and boost on the prostate bed was given up to total dose of 63-72 Gy (median, 64.8 Gy) in conventional fractionation. The proportion of patients given hormonal therapy and the pattern in which it was given were analyzed. Primary endpoint was biochemical relapse-free survival (bRFS) after radiotherapy completion. Secondary endpoint was overall survival (OS). Biochemical relapse was defined as a prostate-specific antigen level above 0.2 ng/mL. Results: After median follow-up of 53 months (range, 0 to 104 months), the 5-year bRFS of all patients was estimated 80.4%. The 5-year OS was estimated 96.6%. Patients who were given androgen deprivation therapy had a 5-year bRFS of 95.1% while the ones who were not given any had that of 40.0% (p < 0.01). However, the statistical significance in survival difference did not persist in multivariate analysis. The 3-year actuarial grade 3 chronic toxicity was 1.7% and no grade 3 acute toxicity was observed. Conclusion: The biochemical and toxicity outcome of post-radical prostatectomy radiotherapy in our institution is favorable and comparable to those of other studies.

Comparison between preoperative and postoperative concurrent chemoradiotherapy for rectal cancer: an institutional analysis

Lee, Jeong Won,Lee, Jong Hoon,Kim, Jun-Gi,Oh, Seong Taek,Chung, Hyuk Jun,Lee, Myung Ah,Chun, Hoo Geun,Jeong, Song Mi,Yoon, Sei Chul,Jang, Hong Seok The Korean Society for Radiation Oncology 2013 Radiation Oncology Journal Vol.31 No.3

Purpose: To evaluate the treatment outcomes of preoperative versus postoperative concurrent chemoradiotherapy (CRT) on locally advanced rectal cancer. Materials and Methods: Medical data of 114 patients with locally advanced rectal cancer treated with CRT preoperatively (54 patients) or postoperatively (60 patients) from June 2003 to April 2011 was analyzed retrospectively. 5-Fluorouracil (5-FU) or a precursor of 5-FU-based concurrent CRT (median, 50.4 Gy) and total mesorectal excision were conducted for all patients. The median follow-up duration was 43 months (range, 16 to 118 months). The primary end point was disease-free survival (DFS). The secondary end points were overall survival (OS), locoregional control, toxicity, and sphincter preservation rate. Results: The 5-year DFS rate was 72.1% and 48.6% for the preoperative and postoperative CRT group, respectively (p = 0.05, the univariate analysis; p = 0.10, the multivariate analysis). The 5-year OS rate was not significantly different between the groups (76.2% vs. 69.0%, p = 0.23). The 5-year locoregional control rate was 85.2% and 84.7% for the preoperative and postoperative CRT groups (p = 0.98). The sphincter preservation rate of low-lying tumor showed significant difference between both groups (58.1% vs. 25.0%, p = 0.02). Pathologic tumor and nodal down-classification occurred after the preoperative CRT (53.7% and 77.8%, both p < 0.001). Acute and chronic toxicities were not significantly different between both groups (p=0.10 and p = 0.62, respectively). Conclusion: The results confirm that preoperative CRT can be advantageous for improving down-classification rate and the sphincter preservation rate of low-lying tumor in rectal cancer.

Purpose: To evaluate the treatment outcomes of preoperative versus postoperative concurrent chemoradiotherapy (CRT) on locally advanced rectal cancer. Materials and Methods: Medical data of 114 patients with locally advanced rectal cancer treated with CRT preoperatively (54 patients) or postoperatively (60 patients) from June 2003 to April 2011 was analyzed retrospectively. 5-Fluorouracil (5-FU) or a precursor of 5-FU-based concurrent CRT (median, 50.4 Gy) and total mesorectal excision were conducted for all patients. The median follow-up duration was 43 months (range, 16 to 118 months). The primary end point was disease-free survival (DFS). The secondary end points were overall survival (OS), locoregional control, toxicity, and sphincter preservation rate. Results: The 5-year DFS rate was 72.1% and 48.6% for the preoperative and postoperative CRT group, respectively (p = 0.05, the univariate analysis; p = 0.10, the multivariate analysis). The 5-year OS rate was not significantly different between the groups (76.2% vs. 69.0%, p = 0.23). The 5-year locoregional control rate was 85.2% and 84.7% for the preoperative and postoperative CRT groups (p = 0.98). The sphincter preservation rate of low-lying tumor showed significant difference between both groups (58.1% vs. 25.0%, p = 0.02). Pathologic tumor and nodal down-classification occurred after the preoperative CRT (53.7% and 77.8%, both p < 0.001). Acute and chronic toxicities were not significantly different between both groups (p=0.10 and p = 0.62, respectively). Conclusion: The results confirm that preoperative CRT can be advantageous for improving down-classification rate and the sphincter preservation rate of low-lying tumor in rectal cancer.
