        한방병원에 입원한 노인암 환자의 치료 특성 분석

        오혜경,이지영,류한성,윤성우,Oh, Hye-kyung,Lee, Jee-young,Ryu, Han-sung,Yoon, Seong-woo 대한한방내과학회 2016 大韓韓方內科學會誌 Vol.37 No.2

        Objective: Because the number of geriatric cancer patients is on the rise but information on treatments for this population is limited, this study aimed to analyze clinical characteristics and the factors that influence treatment decisions among elderly cancer patients.Method: Data on elderly cancer patients (≥65 years of age) who were admitted to a traditional Korean medicine hospital from March 2014 to February 2016 were collected. We compared the clinical characteristics and overall survival rates of the chemotherapy group and the non-chemotherapy group.Results: Nineteen patients were included in this study. Nine people received chemotherapy, and ten people did not receive chemotherapy due to concerns about quality of life. Age, activities of daily living (ADL) score, and Eastern Cooperative Oncology Group (ECOG) performance status all showed differences between the two groups, although median survival times did not differ significantly between the two. Compared with chemotherapy alone, traditional Korean medicine combined with chemotherapy prolonged median survival times.Conclusion: Old age and low ECOG performance status and ADL scores appear to be influential factors for the decision to undergo chemotherapy. Further studies are needed to confirm that these factors influence decisions about cancer treatment methods among geriatric cancer patients.

And smaller space is required for the maser bedroom and master bathroom.

      • Small sized lung SBRT 치료시 폐 실질 조직에서의 계획선량 전달 정확성 평가

        오혜경,손상준,박장필,이제희,Oh, Hye Gyung,Son, Sang Jun,Park, Jang Pil,Lee, Je Hee 대한방사선치료학회 2019 대한방사선치료학회지 Vol.31 No.1

        목 적: 본 연구에서는 lung SBRT가 적용되는 작은 계획 표적 용적(PTV)에 처방 선량이 정확히 전달되는지 실험을 통하여 알아보고자 한다. 치료계획 시스템에서 계산된 선량분포와 실험을 통하여 필름에 측정된 선량분포를 비교 분석하여 정확성을 평가해보고, 폐 실질 조직 내에서 계획 표적 용적의 margin 유용성 평가를 하고자 한다. 대상 및 방법: CT 촬영으로 얻은 Rando phantom 3D 영상의 우측 폐에 직경 2, 3, 4, 5 cm인 가상의 구 표적을 만들어 계획 표적 용적에 처방선량의 95 %가 전달될 수 있도록 6MV-FFF VMAT Arc 2개로 치료계획을 수립하였으며, Eclipse TPS와 동일한 위치에서 선량 비교하기 위해서, 필름을 가상 표적의 회전중심점에 횡단면 방향으로 삽입하고 방사선을 조사하였다. Dose profile을 Eclipse에서 획득하고, 측정값과 계산값을 비교하기 위해 Center point에서의 절대 선량값을 계산하였으며, off-axis 선량 분포를 얻어 RMSE, Coverage ratio 등 비교 인자를 통해 상대 선량 및 선량분포를 비교 분석하였다. 결 과: 직경 2, 3, 4, 5 cm 크기별로 center point에서의 %difference 값은 직경 2 cm에서 -4.65 %로 가장 차이가 큰 값을 보였고, 직경 5 cm일 때 -1.46 %로 가장 차이가 작은 값을 보였다. RMSE값은 직경 2 cm일 때 3.43으로 가장 큰 값을 보였고. 직경 5 cm일 때 2.85로써 가장 작은 값을 보였다. 표적 커버리지를 비교하기 위해 처방선량 95 %가 들어가는 용적의 길이($D_{95}$)를 구하였고, 직경 2 cm일 때, TPS와 필름에서 각각 2.02 cm, 1.86 cm로 커버리지 비율이 92 %로 나타났고 가장 큰 차이를 보였다. 또한 계획 표적 용적 100% 이내에 들어가는 평균선량($D_{mean}$)을 비교했을 때, 직경 2 cm 인 경우 측정 평균선량이 95.72 %로 가장 낮은 값을 보였다. 결 론: 본 연구에서는 실험을 통하여 작은 계획 표적 용적에 처방 선량이 충분히 전달되는지 알아보았다. 실험 결과 모든 비교 인자에서 직경 2 cm인 용적이 가장 큰 차이를 보였다. 이는 표적 용적 중심에서의 선량 감소가 주요인이라 판단된다. 따라서 선량계산 시스템에서 저밀도 조직 내의 작은 용적 치료 계획시 2 mm 이상의 마진(margin)을 더 두거나, 치료 계획 최적화(optimization)시 최대선량을 제한하지 않는 방법으로 표적 내 중심 선량을 높일 수 있을 것이라 사료된다. Purpose: The purpose of this study is to evaluate beam delivery accuracy for small sized lung SBRT through experiment. In order to assess the accuracy, Eclipse TPS(Treatment planning system) equipped Acuros XB and radiochromic film were used for the dose distribution. Comparing calculated and measured dose distribution, evaluated the margin for PTV(Planning target volume) in lung tissue. Materials and Methods : Acquiring CT images for Rando phantom, planned virtual target volume by size(diameter 2, 3, 4, 5 cm) in right lung. All plans were normalized to the target Volume=prescribed 95 % with 6MV FFF VMAT 2 Arc. To compare with calculated and measured dose distribution, film was inserted in rando phantom and irradiated in axial direction. The indexes of evaluation are percentage difference(%Diff) for absolute dose, RMSE(Root-mean-square-error) value for relative dose, coverage ratio and average dose in PTV. Results: The maximum difference at center point was -4.65 % in diameter 2 cm size. And the RMSE value between the calculated and measured off-axis dose distribution indicated that the measured dose distribution in diameter 2 cm was different from calculated and inaccurate compare to diameter 5 cm. In addition, Distance prescribed 95 % dose($D_{95}$) in diameter 2 cm was not covered in PTV and average dose value was lowest in all sizes. Conclusion: This study demonstrated that small sized PTV was not enough covered with prescribed dose in low density lung tissue. All indexes of experimental results in diameter 2 cm were much different from other sizes. It is showed that minimized PTV is not accurate and affects the results of radiation therapy. It is considered that extended margin at small PTV in low density lung tissue for enhancing target center dose is necessary and don't need to constraint Maximum dose in optimization.

      • 한약 및 천연물의 항암 임상연구 방법론에 대한 고찰

        오혜경,이지영,류한성,윤성우,Oh, Hye Kyung,Lee, Jee Young,Ryu, Han Sung,Yoon, Seong Woo 대한암한의학회 2015 大韓癌韓醫學會誌 Vol.20 No.1

        Objectives : The cancer incidence and cancer burden is increasing. In addition, the use of botanical agents in cancer care is increasing. This article aims to review a research strategy for botanical agents. Methods : The clinical studies of anticancer botanical agents and the papers about clinical research methodology of botanical agents were reviewed. Results : In phase I study, safety confirmation, optimal dose determination and drug interaction study are important. Most botanical agents have low toxicity and some have non-monotone dose response. Therefore, dose-response curve must be evaluated separately from the dose-toxicity curve to determine optimal dose. Although anticancer botanical agents can't shrink tumor size rapidly, they do extend survival. So, in phase II study, response should be evaluated by the survival. Conclusions : Clinical research of botanical agents in cancer is different from traditional methods and strategies. Considering the characteristics of botanical agents and experimental mechanism is necessary in conducting botanical based clinical trials.

        오혜경(Oh Hye-Kyung),황성혜(Hwang Seong-Hye) 가정과삶의질학회 2009 가정과삶의질연구 Vol.27 No.1

        The purpose of this study is to analyze the effectiveness of a host family experience program on the adaptive behavior and self-management skills of children with severe disabilities and to suggest its applicability into clinical practice. The investigators developed a host family experience program and researched the pre-test and post-test designs with nonequivalent groups. The experiment and comparison groups were comprised of 34 children with severe disabilities that lived at S, a care facility for the severely disabled. They were examined for the program's effects on them before and after the application. After analyzing 17 cases for differences in the subjects' quantitative scores, a qualitative analysis was carried out on one representative case. The quantitative analysis results reveal that the experiment group showed a significant increase in their scores of adaptive behavior and self-management skills compared to the comparison group. Positive changes were also observed among the former group in the qualitative analysis. Thus the host family experience program was effective in improving the adaptive behavior and self-management skills of the children with severe disabilities at the facility. These findings indicate that the host family experience program played a positive role in enhancing the adaptive behavior and self-management skills of the children with severe disabilities at the facility and that such host family experience programs should be applied and reinforced in the field of social welfare practice.
