  • 목 적 : 가와사끼병 환아의 특성과 관상동맥 이상, IVIG에 대한 비반응 및 병의 재발 등에 대해 관련된 인자를 찾아보고자 하였다. 방 법 : 1990년 9월부터 2003년 12월까지 본원에 내원, 가와사끼 병으로 진단받고 IVIG을 투여한 1,000명을 대상으로 후향적으로 분석하였다. 내원시 관상동맥 확장군과 관상동맥 정상군을 비교하였고 IVIG 1회 투여에 대한 반응군과 비반응군 및 재발군과 비재발군의 비교도 시행하여 두 군간에 의미있는 요인을 찾아보려고 하였으며 재발된 환아를 대상으로 처음 발병시와 두번째 발병시의 각종 자료를 분석하였고 두 군간에 관상동맥 이상이 생기는 정도도 비교해 보았다. 또한 첫 IVIG을 투여하기 전까지의 발열기간과 상관비례하는 인자를 알아보려 하였다. 결 과 : 1) 관상동맥 확장은 16%에서 관찰되었으며 중등도 이상(${\geq}5mm$)의 관상동맥 확장 및 중증(${\geq}8mm$) 관상동맥 확장의 빈도는 각각 2%와 0.5%로 나타났다. 또한 입원당시 관상동맥 이상의 빈도는 1년간 추적관찰 했을 때와도 비슷한 수준을 보였다. 2) 첫 IVIG을 투여하기 전까지의 발열기간이 길수록(7일 이상), 첫 IVIG 투여 종료 후부터 최종적으로 열이 소실될 때까지의 기간이 길수록, 남아일수록, 내원 당시 검사상 Hgb(10 g/dL이하), Hct(30% 이하)수치가 낮을수록, WBC 수치($12,000/mm^3$ 이상)및 과립구 분율이 높을수록, CRP 값이 높을수록(10 mg/dL 이상), Harada's score가 높을수록(4점 이상) 관상동맥 이상군과 관련이 있었다. 3) IVIG 한번 투여에 반응이 없었던 경우는 8%였으며 내원당시 검사수치상 WBC 수치가 높을수록($12,000/mm^3$ 이상), 과립구 분율이 높을수록, CRP 수치가 높을수록(10 mg/dL 이상), SGPT가 높을수록, Harada's score가 높을수록(4점 이상), 농뇨를 보일수록 1회의 IVIG 투여에 반응이 없었다. IVIG을 두 번이상 투여한 군에서는 한번 투여에 반응이 있었던 군보다 향후 재발율이 더 높았다. 또한 중증도 이상의 관상동맥 확장의 경우는 두 번 이상 투여하게 된 군에서 의미있게 높았다. 4) 재발은 6%에서 나타났고 재발을 예측할 수 있는 지표는 없었으며 재발한 환아들에서 관상동맥 이상의 빈도 또한 별 차이가 없었다. 5) 재발된 환아들의 처음 발병시와 두 번째 발병시의 비교에서, 두 번째 발병시에 WBC 수치와 CRP 값은 첫 번째 발병시 보다 낮았고 첫 IVIG 투여 전까지의 발열기간도 낮았으나 두 군간에 관상동맥 이상이 생기는 정도에는 차이가 없었다. 6) 첫 IVIG을 투여하기 전까지의 발열기간과의 상관 인자 조사에서는, WBC 수치와 CRP 값, Harada's score의 경우 양의 상관관계를 보였고 Hgb의 경우 음의 상관관계를 보였다. 결 론 : 내원 당시 높은 WBC 수치와 CRP 값 및 Harada'score는 관상동맥 병변 발생 및 IVIG 투여에 대한 비반응과 관련이 있으며 또한 첫 IVIG을 투여하기 전까지의 발열기간과도 상관관계가 있었다. 따라서 되도록이면 조기에 발견하여 IVIG을 투여하는 것이 비록 비반응률을 낮추지는 못하더라도 관상동맥 병변 발생의 위험률은 낮출 수 있을 것으로 생각된다. 또한 IVIG 비반응군에서는 차후 재발률이 더 높았으며 중등도 이상의 관상동맥 확장이 더 많이 발견되었으므로 이들을 대상으로 한 집중적인 치료와 관리가 도입될 필요가 있다. 재발을 예측할 수 있는 기타 지표는 찾아볼 수 없었으며 따라서 보호자의 교육을 통한 조기 발견 및 치료에 지속적으로 노력을 기울여야 할 것이고 재발한 환아들에서 관상동맥 이상의 빈도가 증가하지 않은 점은 현재 이루어지고 있는 이러한 노력의 성과로 여겨진다.

  • 방사선 단독 치료나 수술후 방사선 치료를 받았던 165명의 식도암 환자 중에서 평균 생존율은 6.6개원이였으며 3,5년 생존율은 $10\%,\;8\%$였다. 생존율을 semilogarithmical하게 나타낸 biphasic plotting에서 보면 non-responder group은 치료에도 불구하고 1년내 모두 사망하였고 responder group중에서는 수술후 방사선 치료를 받았던 환자 20명 $(54\%)$은 1, 2, 3년 생존율이 각각$80\%,\;70\%,\; 60%$였으며, 방사션 치료만 받은 환자 61명$(48\%)$의 생존율은 각각 $62\%,\;38\%,\;23\%$였다. 즉, 3년간의 생존율의 비교는 수술후 방사선 치료가 방사선 단독치료 보다는 좋았다 (P<0.01). 가장 많은 사망의 원인으로는 연하곤란$(55\%)$이였으며 환자의 대다수는 국소적인 치료실패에 의해 사망하였으며 $(62\%)$ 협착의 $88\%$는 지속적인 암의 존재와 관련이 있었다. 환자의 $50\%$는 국소적인 임파절 전이가 발견되었다. 수술전의 진단 실패율은 $54\%$가 국소임파절 전이 때문에, $29.7\%$가 육안적인 임파절 전이 때문에, $13.5\%$가 혈행성 전이 때문에 그리고 $14\%$가 국소적인 직접 침범 때문이였다. Conventional radiation (6000 cGy/30 fraction in 6 weeks)이나 hyperfractionation radiation (upto 6900cGy, l15cGy/fraction)이거나 관계없이 gross disease는 충분히 즉일수 없었다. 그러나 hyperfractionation 테크닉에 의해서 급성 방사선 염증이 감소되어서 환자의 고통을 덜어줄 수 있었으며 그 후의 만성 부작용으로서의 방사선 합병증이 현저히 감소되었다.

  • The purpose of this study was to verify the importance of apoptosis in genesis of osteosarcoma and whether apoptosis may play an important role as a predictive factor for the response to chemotherapy. Of the patients who were diagnosed osteosarcoma between January 1995 and June 1999, ten patients were selected. All specimens were obtained before and after preoperative chemotherapy and examined for the occurrence of apoptosis. Apoptosis was investigated by in situ end-labeling technique on paraffin-embedded sections and apoptotic indices were calculated before and after chemotherapy. The ages of ten patients ranged from 15 to 59 with equal sex ratio. All patients completed the planned pre-operative chemotherapy. Apoptosis occurs in osteosarcoma and apoptotic indices are increased after chemotherapy. Mean apoptotic index (AI) before and after chemotherapy were 17.2 (range 6-28.9) and 26.3 (9.6-46.2), respectively. Apoptotic cells were usually present around the necrotic area. The AI was increased as the progression of stage and in responder group more than in non-responder. Apoptosis is induced by pre-operative chemotherapy and the response is variable. Changes in AI levels before and after chemotherapy may possibly predict an individual patient's overall response.

  • Background: We examined the usefulness of urine osmolality, as a predictive factor in the treatment of monosymptomatic nocturnal enuresis (NE) with combination therapy of imipramine and desmopressin. Methods: From May 2014 to April 2015, 59 monosymptomatic NE patients participated in this study. Early morning urine osmolality was measured at 1 week and 1 day before combination therapy of imipramine and desmopressin, and at 1 week and 2 weeks after therapy. The response to combination therapy was evaluated at 3 months after treatment. The mean period of combination therapy was $6.4{\pm}4.2weeks$. Therapeutic response was classified as complete (0-1 wet night/week), partial (over 50% reduction of night) and non-responders (less than 50% reduction of night). Results: The cumulative rate of the complete and partial responders was 76.3%. Among the 3 groups, the statistically lowest value of pre-treatment urine osmolality was observed in the complete responder group (p<0.001). Urine osmolality increased in all groups after treatment, however, statistically the greatest difference between pre and post-treatment urine osmolality was observed in the complete responder group (p=0.024). No serious side effects were observed. Conclusion: Early morning urine osmolality and change of urine osmolality between pre and post-treatment have predictive values in the response to combined imipramine and desmopressin for treatment of monosymptomatic NE.

  • Objective : Mechanical thrombectomy (MT) for acute intracranial internal carotid artery (ICA) occlusion is often complicated by difficult revascularization and non-involved territory embolization possibly related with larger clot-burden. This study aims to evaluate the efficacy of proximal aspiration thrombectomy (PAT) using a balloon-tipped guide catheter for clot-burden reduction in such cases with period-to-period analysis (period 1 : standard MT without PAT; period 2 : PAT first, then standard MT for the remaining occlusion). Methods : Eighty-six patients who underwent MT for acute intracranial ICA occlusion were included in this analysis from the prospectively maintained stroke registry (33 patients in period 1 and 53 in period 2). In period 2, 'responder' was defined as a case where some amount of clot was retrieved by PAT and the following angiography showed partial or full recanalization. Results : Fifteen of fifty-three patients in period 2 (28.3%) were 'responders' to PAT. There was a significantly higher incidence of atrial fibrillation in the 'responder' subgroup. Period 2 showed a significantly shorter puncture-to-reperfusion time (94.5 minutes vs. 56.0 minutes; p=0.002), a significantly higher Thrombolysis in Cerebral Infarction of 2b-3 reperfusion (45.5% vs. 73.6%; p=0.009), but only a trend for better 3-month favorable outcome (mRS 0-2; 36.4% vs. 54.7%; p=0.097). There was no increase in the incidence of procedure-related complications or intracranial hemorrhage in period 2. Conclusion : A strategy of PAT before standard MT may result in shorter puncture-to-reperfusion time and better angiographic outcome than a strategy of standard MT for acute intracranial ICA occlusion.

  • Background: Prior studies have reported that 40%-90% of the patients with celiac plexus-mediated visceral pain benefit from the neurolytic celiac plexus block (NCPB), but the predictive factors of response to NCPB have not been evaluated extensively. This study aimed to identify the factors associated with the immediate analgesic effectiveness of NCPB in patients with intractable upper abdominal cancer-related pain. Methods: A retrospective review was performed of 513 patients who underwent NCPB for upper abdominal cancer-related pain. Response to the procedure was defined as (1) a decrease of ≥ 50% or ≥ 4 points on the numerical rating scale (NRS) in pain intensity from the baseline without an increase in opioid requirement, or (2) a decrease of ≥ 30% or ≥ 2 points on the NRS from the baseline with simultaneously reduced opioid consumption after NCPB. Logistic regression analysis was performed to determine the factors associated with successful responses to NCPB. Results: Among the 513 patients included in the analysis, 255 (49.8%) and 258 (50.2%) patients were in the non-responder and responder group after NCPB, respectively. Multivariable logistic regression analysis showed that diabetes (odds ratio [OR] = 0.644, P = 0.035), history of upper abdominal surgery (OR = 0.691, P = 0.040), and celiac metastasis (OR = 1.496, P = 0.039) were the independent factors associated with response to NCPB. Conclusions: Celiac plexus metastases, absence of diabetes, and absence of prior upper abdominal surgery may be independently associated with better response to NCPB for upper abdominal cancer-related pain.

  • Purpose : It is very important to endow the cancer patients underwent chemotherapy with satisfactory quality of life (QOL). However, little is known about the factors influencing QOL during chemotherapy. Therefore, we designed this study to find out the factors influencing QOL in the cancer patients who underwent chemotherapy. Methods : Ninety-seven cancer patients were studied, prospectively. The patients' characteristics were as follows; median age(range): 48(19{\sim}83) years, male:female; 57:40, PS:0,1/2,3;55/42 patients, diagnosis(number): lymphoma (28), lung cancer (22), gastrointestinal cancer (18), sarcoma (12), breast cancer (12), gynecological cancer (5), Stage: I,II/III.IV;37/60 patients. We used EORTC QLQ-C30 questionnaires to evaluate QOL. EORTC QLQ-C30 scores were performed before the onset of chemotherapy and after the end of 3 cycles of chemotherapy. The correlation of these scores with performance status (PS), diagnosis, disease stage, response to chemotherapy, and regimen related toxicity was evaluated. Results : The responder group (CR, PR) demonstrated marked improvement of social functional and emotional scales to non-responder group (SD,PD) (P=0.024, 0.045). Non-hematologic regimen related toxicity such as mucositis, nausea and vomiting was significantly correlated with pain scale change (P=0.043). Other factors had no notable correlation with QOL changes. Conclusion : Our preliminary study results may suggest as follows. The response to chemotherapy is associated with the change of social functional and emotional scales and the severity of non-hematologic regimen related toxicity is associated with pain scale change.

  • Purpose: We sought to evaluate the clinical outcomes of 3-dimensional conformal radiation therapy (3D-CRT) for portal vein tumor thrombosis (PVTT) alone in patients with advanced hepatocellular carcinoma. Materials and Methods: We retrospectively analyzed data on 46 patients who received 3D-CRT for PVTT alone between June 2002 and December 2011. Response was evaluated following the Response Evaluation Criteria in Solid Tumors. Prognostic factors and 1-year survival rates were compared between responders and non-responders. Results: Thirty-seven patients (80.4%) had category B Child-Pugh scores. The Eastern Cooperative Oncology Group performance status score was 2 in 20 patients. Thirty patients (65.2%) had main or bilateral PVTT. The median irradiation dose was 50 Gy (range, 35 to 60 Gy) and the daily median dose was 2 Gy (range, 2.0 to 2.5 Gy). PVTT response was classified as complete response in 3 patients (6.5%), partial response in 12 (26.1%), stable disease in 19 (41.3%), and progressive disease in 12 (26.1%). There were 2 cases of grade 3 toxicities during or 3 months after radiotherapy. Twelve patients in the responder group (15 patients) received at least 50 Gy irradiation, but about 84% of patients in the non-responder group received less than 50 Gy. The 1-year survival rate was 66.8% in responders and 27.4% in non-responders constituting a statistically significant difference (p = 0.008). Conclusion: Conformal radiotherapy for PVTT alone could be chosen as a palliative treatment modality in patients with unfavorable conditions (liver, patient, or tumor factors). However, more than 50 Gy of radiation may be required.

  • According to the recent epidemiological data, the numbers of patients of Reumatoid Arthritis(RA) in the world are reported to be 350mi11ion and 700,000 in the world and in Japan, respectively For the treatment of RA, NASIDs as the first choice drug have been widely used worldwide, and more than 50 NSAIDs have been in market up to today in Japan. Early 1990s, DMARDs as the new drug for RA treatment came into market, and the number of DMARDs has been increased every year. These drugs are recognized to have several advantages in treatment of RA, however, disadvantages are also reported, i.e., (1) high incidence of side effects, (2) high non-responder population, (3) decreased efficacy in chronic treatment, and (4) slow starting of the efficacy. For example, Methotrexate which has been widely used as the immunosuppressant has been recently used for treatment of Reumatoid. However, this drug has several disadvantages such as 60-70% improvement of the disease, 80% incidence of side effects, and 2-4 weeks to recognize the efficacy after treatment. In addition to these two.

  • 연구방법: 수술적 절제가 불가능하거나, 수술을 거부한 40예의 병기 3기와 4기의 비소세포성 폐암환자에서 MVP 복합화학요법을 2회이상 시행하였다. 결과: 1) 반응률에 있어서는, 부분 관해를 보인 예는 9예(23%)였으며, 23예(57%)에서 불변이었고, 8예(20%)에서 진행성 병변을 보였다. 완전 관해를 보인 예는 없었다. 2) 전체적인 중앙생존기간은 36주이었으며, 반응군에서의 중앙생존기간은 60주로서 비반응군의 31주에 비해 유의하게 연장되었다(p=0.03). 3) 여성에서 생존기간이 유의하게 연장되었다(p=0.01). 그외 예후인자인, 나이, 활동도, 조직형, 병기, LDH치, 혈색소치, 혈청 CEA치 등에 따른 반응률과 생존기간의 유의한 차이는 없었으나, 활동도가 양호한 군에서 반응률이, stage IIIa군에서 반응률 및 생존 기간이 높았음이 관찰되었다. 4) 화학 요법만을 받은 군과 고식적인 방사선 요법을 받은 군간의 생존기간의 차이는 없었다. 5) 부작용은 2예(5%)에서 지속적인 백혈구 감소증, 5예(12.5%)에서 말초 신경염이 관찰되었으나, 대다수 예에서 부작용 정도는 가역적이었고, 수용할만 하였다. 결론: 진행된 비소세포성 폐암의 치료에 있어서 MVP 요법은 반응률을 증가시키고 전체적인 생존기간을 연장시키는데 만족스럽지 못하였으나, 반응군에서는 유의하게 생존기간이 연장 되었다. 그래서, 새로운 화학요법의 개발과 아울러 대규모의 대상으로 수술이나 방사선 요법과의 병용치료등에 대한 연구가 필요하겠다.
