  • 연구배경: 소세포폐암은 빠른 증식속도와 조기에 전신전이를 나타내지만 화학요법에 비교적 반응을 잘한다고 알려져 있다. 최근 10년간 CAV에 실패한 환자의 이차 치료로서 사용되던 cisplatin과 etoposide 복합 화학요법(PVP)을 소세포 폐암 환자에서 일차 치료로서 시행하여 높은 반응률을 보고하고 있다. 이에 저자등은 PVP요법의 유효성 및 안정성을 평가하고자 하였다. 방법: 1989년 11월부터 1991년 12월까지 원자력 병원에서 소세포 폐암으로 진단받은 61명의 환자들을 대상으로 cisplatin $30mg/m^2$와 etoposide $100mg/m^2$을 제1일부터 제3일까지 정주하고 매 3주 간격으로 반복 치료하여 그 결과를 판정 하였다. 결과: 총 61명의 환자중 평가가 가능한 55명에서 완전반응이 13예(24%), 부분반응이 29예(53%), 불변이 9예(16%), 진행이 4예(7%)로 총반응률은 77% 였다. 제한기에서는 완전반응이 8예(26%), 부분반응이 21예(68%)였고 확대기에서는 완전반응이 5예(21%), 부분반응이 8예(33%)였으며, 전체 생존기간의 중앙치가 55.8주, 제한기가 61.1주, 확대기가 51.3주였다. 그리고 전체 반응군의 반응유지기간은 29.1주였고 심각한 부작용은 없었다. 결론: 소세포 폐암에 있어서 PVP요법은 일차치료로 사용시 심각한 부작용이 없으면서 비교적 효과적인 복합 화학요법으로 생각된다.

  • Objective : The Korean Association of Anxiety Disorders developed Korean guidelines for treatment of panic disorder (PD) 2018. In this paper, we discussed the consensus among psychiatrists, regarding initial and maintenance treatment strategies for pharmacological treatment of PD in Korea. Methods : Based on current treatment guidelines published by the American Psychiatric Association, the National Institute for Clinical Excellence, and the Canadian Psychiatric Association, we developed questionnaires pertinent to initial and maintenance treatment strategies for pharmacological treatment of PD. Seventy-two experts in PD answered questionnaires. We classified expert opinions into three categories, first, second, and third-line treatment strategies, by analyzing the 95% confidence interval. Results : Antidepressants, benzodiazepine anxiolytics, and cognitive-behavioral therapy (CBT) were recommended as treatments of choice (ToC), and first-line strategies for initial treatment of PD. Escitalopram, paroxetine, sertraline, and venlafaxine were preferred from among many anti-panic drugs. Mean starting dose of anti-panic drugs for initial treatment of PD was relatively lower, than that for other psychiatric illnesses such as major depressive disorder. In the case of maintenance treatment of PD, antidepressants and CBT were selected as ToC and first-line strategies. Patients were typically examined every four weeks during treatment, to review effectiveness and side effects of the drug. Pharmacotherapy was generally continued for one year or more. Conclusion : This study provides information about consensus among Korean experts regarding pharmacological treatment strategies for patients with panic disorder.

  • 목 적 : 비소세포 폐암의 치료용적의 크기가 크거나 폐 용적이 작고, 몸의 정중선(Mid line)에 위치한 경우 척수의 허용선량을 고려한 방사선치료계획에서 폐 선량이 많아지게 되는데, 본 연구는 비소세포 폐암 환자의 3차원입체조형치료(Three dimensional conformal radiotherapy, 3D CRT), 제한된 각도를 이용한 세기변조방사선치료(Intensity modulated radiotherapy, IMRT)와 용적변조회전치료(Volumetric Modulated Arc therapy, VMAT) 치료계획을 각각 적용하여 전체 폐 선량을 비교 및 평가하고자 한다. 대상 및 방법 : TrueBeam STx($Varian^{TM}$, USA) 10 MV 에너지를 이용하여 4명의 환자에 대하여 3D CRT, 제한된 각도를 이용한 IMRT와 VMAT 치료계획을 세우고, 총 선량 66 Gy/30 Fx 처방하였을 때, 선량용적히스토그램(Dose Volume Histogram, DVH)을 이용하여 치료계획용적(Planning Target Volume, PTV), 전체 폐 그리고 척수에 들어가는 선량을 평가하였다. PTV에 대한 처방선량지수(Conformity Index, CI), 선량균질지수(Homogeneity index, HI), 처방선량포함지수(Paddick's Conformity Index, PCI)를 구하고, 폐의 30 Gy 용적($V_{30}$), $V_{20}$, $V_{10}$, $V_5$, 평균선량(Mean dose)을 평가하고, 척수의 최대선량 값을 평가하였다. 결 과 : PTV에 대한 CI, HI, PCI의 평균값은 각각 $0.944{\pm}0.009$, $1.106{\pm}0.027$, $1.084{\pm}0.016$으로 평가되었다. 전체 폐에 대한 첫 번째 환자의 $V_{20}$은 3D CRT, IMRT, VMAT 각각 30.7%, 20.2%. 21.2%, 두 번째 환자의 $V_{20}$은 33.0%, 29.2%. 31.5%, 세 번째 환자의 $V_{20}$은 51.3%, 34.3%. 36.9%, 네 번째 환자의 $V_{20}$은 56.9%, 33.7%. 40%로 제한된 각도를 이용한 IMRT 치료계획에서 가장 낮게 평가되었다. 척수에 대한 최대선량 값은 모두 허용선량 미만으로 평가되었다. 결 론 : 비소세포 폐암의 방사선치료계획에서 3D CRT와 비교했을 때, 제한된 각도를 이용한 IMRT나 VAMT을 이용하면 척수의 허용선량을 넘지 않으면서 폐 선량을 줄여줄 수 있는 치료계획을 세울 수 있었다. IMRT와 VAMT을 비교해보면 PTV의 선량포함과 척수선량을 고려했을 때 IMRT 치료계획에서 보다 좁은 각도를 이용한 치료계획이 가능하였고, 이는 폐 선량을 좀 더 줄여줄 수 있는 결과를 얻을 수 있었다.

  • This paper has surveyed above all what the patients call for physically, psychologically, and socially and researched how the ministers have acknowledge on cancers, their patients and hospice by means of enquete. To the difficulty the pastors should give their hands. This study researched what thoughts and behaviors the ministers actually had by the method of questionnaire. It was done from October 20, 1997 through December 10, 1997 on seven thousand of questionnaire paper of which 149 given back on the line of post or firsthandly were analyzed. The questioness consisted of 141 men(94.6%), 8 women(5.4) and 104 pastor on appentice(69.8%). There were 58 questionees(38.9%) who were hospitalized of their own diseases, and 121 questionees(81.3%) who had cancer patients hospitalized among their church people, relatives, or friends. Most of all the questionees(79.9%) had not any experience, such as they took some instruction about cancer patients. 72.5% of all the questionees had not ever served patients around them. The followings are the contents of the enquete: the questionees' view to chronic patients and death, where they put the priority in the case of that they look after patients who are under terrible pain ahead of death, what they think of such a situation as a patient has no technical possibility to be recuperated, why they think pastors do not like to visit chronics, which therapy they choose, whether they mainly control their pain or they do their best in order to heal their diseases, how much the questioned ministers know hospice, where and how they get the information on it, how much important role they play in the hospice team, whether the volunteers for hospice have not worked on account of pastors' misunderstanding to hospice service, whether the ministers want to take part in hospice service with their church people or not, and so forth. Suggestion: First, the education and P.R. about hospice are requested for the ministers. Second, the ministers must participate in hospice activities actively. Therefore the ministers and the churches must firsthandly take part in hospice activities beyond the education only and the raising of the recognition to them.

  • Background: Pemetrexed has been prescribed newly as a second line chemotherapy in advanced non-small cell lung carcinoma (NSCLC). The aim of study was to determine the efficacy and toxicity of pemetrexed in advanced NSCLC. Methods: Patients with histologically or cytologically confirmed NSCLC were evaluated from June 2006 to December 2008. The patients had relapsed or progressed after prior chemotherapy treatment. They were treated with intravenous pemetrexed $500mg/m^2$ for 10 min on Day 1 of each 21-day cycle. Results: A total of 89 patients were eligible for analysis. The response rate and disease control rate were 11% and 66%. Non-squamous cell carcinoma histology was significantly associated with a superior response rate (p=0.035) and disease control rate (p=0.009) than squamous cell carcinoma histology. The median survival time was 13 months and the median progression free survival time was 2.3 months. The median survival time of patients with ECOG PS 0~1 was 13.2 months, whereas median survival time was 11.6 months for patients with PS 2 (p=0.002). The median progression free survival time of patients with PS 0~1 were 3.8 months, but 2.1 months for patients with PS 2 (p=0.016). The median progression free survival time of smokers with non-squamous cell carcinoma was 3.4 months, which was significant (p=0.014). Grade 3~4 neutropenia were seen in 7.9% patients. Conclusion: Pemetrexed has efficacy in patients who had prior chemotherapy with advanced NSCLC and less hematologic toxicity.

  • Background: It has been demonstrated that neutrophil:lymphocyte (NLR) and platelet:lymphocyte (PLR) ratios are associated with prognosis in cancer patients. The aim of this study was to investigate whether pretreatment white blood cell (WBC), neutrophil, lymphocyte, monocyte, platelet, basophil and eosinophil counts, LDH level, NLR and PLR are associated with prognosis in patients with malignant pleural mesothelioma (MPM). Materials and Methods: We retrospectively reviewed files of 50 patients who were managed with a diagnosis of MPM between 2005 and 2010. Demographic and clinical characteristics, treatments, response to treatment and prognostic factors were evaluated, along with relationships between pretreatment blood parameters and prognosis. Results: Overall, 38 men and 12 women were included to the study. Mean age was $61.5{\pm}9.4$ years (range: 39-83 years). There was advanced disease in 86% (n=43) and the histological type was epithelial mesothelioma in the majority (82%). Of the cases, 17 (34%) received radiotherapy, while 42 cases underwent first- and second-line chemotherapy, with cisplatin plus pemetrexed as the most commonly used regimen. In the assessment after therapy, it was found that there was complete response in 4 cases (8%), partial response in 10 cases (20%), stable disease in 17 cases (34%) and progression in 19 cases (38%). Median follow-up was 10 months (range: 10 day-30 months). Median overall survival was found to be 20.7 months while median progression-free survival as 10 months. In univariate and multivariate analyses, it was found that factors significantly affecting overall survival included stage (p=0.030), response to treatment (p=0.026) and monocyte count (p=0.004), while factors affecting disease-free survival included NLR (p=0.018), response to treatment (p=0.001), and PLR score (p=0.003). Conclusions: Overall and disease-free survival was found to be better in cases with a WBC count<8.000, platelet count<300,000, and low NLR and PLR scores in malignant pleural mesothelioma.

  • Background: Metastatic renal cell carcinoma (mRCC) status as poor prognosis improved with the introduction of tyrosine-kinase inhibitors, especially sunitinib. There is sparse data reporting from our region on use of sunitinib in metastatic RCC. Thus the present study explores sunitinib usage at our institute. Materials and Methods: An unselected population of patients with metastatic RCC receiving sunitinib was analyzed with respect to patient characteristics, response, toxicity, and outcomes. Results: Fourty-nine patients with a median age of 50.5 years (range 21-71 years) were included. Most were male (61.2%). Twenty‑one (42.9%) had metastatic disease at presentation. Sunitinib was first line therapy in 45. Conventional clear cell carcinoma was the most common pathology present (39 patients; 79.59 %). The most common site of metastasis was the lung (75.5%). Most patients (30) were started at a dose of 50 mg once a day for 4 weeks and then 2 weeks rest. Clinical benefit rate was 73.5% (n= 36), and 22.5% (n= 11) demonstrated progressive disease at first imaging evaluation within the first 3-6 months. The following objective response performed for patients was 48.9% (n=24) and progression at 24.5 % (n=12). The median follow‑up was 16 months (range, 4-34 months), the overall estimated median PFS was 9 months and the estimated median OS was 15 months. Conclusions: This study demonstrated sunitinib is tolerable and effective in advanced/metastatic RCC Egyptian patients and indicates we should further seek second and third lines to increase survival equivalence as reported in the worldwide literature.

  • Objectives: The purpose of this study was to compare antibiotic resistance patterns between first urinary tract infection (UTI) and recurrent UTI groups and to obtain information regarding empirical antibiotic selection for treating recurrent UTI. Methods: We retrospectively reviewed 148 children treated for UTIs from January 2009 to June 2016. The patients were divided into two groups: first UTI (N = 148) and recurrent UTI (17 patients and 20 episodes). Results: In both groups, Escherichia coli was the most frequent causative organism, accounting for 89.9% and 75.0% in the first and recurrent UTI groups, respectively. When E. coli or Klebsiella pneumoniae was the causative organism, extended-spectrum ${\beta}-lactamase$ (ESBL)-producing organisms were more frequent in the recurrent UTI group (17.6%) than in the first UTI group (14.0%); however, this difference was not statistically significant (P = 0.684). Cefotaxime was the most frequently used first-line empirical antibiotic in both groups. In the first UTI and recurrent UTI groups, 7.4% and 15.0% of patients were treated with intravenous antibiotics as definitive therapy, respectively (P = 0.250). Fifteen out of 17 patients having a second UTI had different causative organisms or antibiotic susceptibility patterns compared to their previous episode. Conclusions: Escherichia coli was the most frequent causative organism in the recurrent UTI group. There were no differences in the proportion of ESBL-producing organisms between the first UTI and recurrent UTI groups. Therefore, when a UTI recurs in children, the antibiotics effective on the most common causative organism might be administered as empirical antibiotics.

  • 연구배경 : 오늘날 폐결핵의 치료에 있어 폐절제술이 폐결핵 치료의 보조적 역할을 하게 됨으로써 수술뿐 만 아니라 술전 및 술후 투약의 중요성이 강조되었다. 그러나, 폐결핵의 폐절제술 후 투약기간에 대해서는 관련 논문의 저자에 따라, 참고 문헌에 따라 다양하고 차이가 있다. 이에 본 연구는 폐결핵환자에서 폐절제술 후 투약 기간에 따른 재발율을 후향적으로 비교 분석함으로써 술후에 적절한 투약기간을 찾고자 하였다. 방법 : 국립마산결핵병원에서 1993년 1월부터 1998년 12월까지 폐절제술이 시행된 95예 중 수술 후 항결핵제로 치료종결하고 추적관찰이 가능했던 예, 술후 투약 중 치료실패 하였으나 약제 변경 등을 통하여 무사히 치료종결하고 추적관찰이 가능하였던 예, 술후 투약을 조기에 종결하고 추적관찰 가능하였으며, 재발 또는 악화된 예를 포함하여 총 66예를 대상으로 진료기록을 중심으로 조사하였다. 치료종결 후 술후 투약기간을 6, 9, 12, 18, 24개월 단위별, 기준별로 분류하여 각 군의 재발율을 ${\chi}^2$-test를 이용하여 비교 분석함으로써 술후 투약기간의 적절성 여부를 판정하였고, 연속 변수에 대하여는 student t-test를 이용하여 비교하였다. 결과 : 대상 환자 66 중 남자가 53예, 여자가 13예 이었고 16세에서 63세의 연령분포를 보였으며 중앙치가 33.5세 였다. 술후에 짧게는 2.7개월, 길게는 28.8개월 동안 투약하였고, 평균 투약기간은 12.9개월이었고, 술후 추적관찰기간은 평균 39.7개월이었다. 추적관찰 기간 중에 5예(7.6%)의 재발이 있었다. 과거력의 수가 2 이하인 군에서 술후 6개월 이하 투약군 10예 중에 2예(20%)의 재발이 발생하였고, 술후 6개월 초과 투약군 43예 중 1예(2.3%)의 재발이 발생하여 유의한 재발율의 차이를 보였다(p=0.03). 과거력의 수가 3이상인 군에서 술후 18개월 이하 투약군 9예 중에는 재발이 없었고, 18개월 초과 투약군 4예 중 2예(50%)의 재발이 발생하여 유의한 재발율의 차이를 보였다(p=0.02). 술후에 이차항결핵제사용군과 혼합약제사용군 사이에 투약기간의 차이는 없었으나, 일차항결핵제사용군과는 두 군이 모두 유의한 차이를 보였다. 이차항결핵제사용군에서는 술후에 평균 15.1개월의 투약 후 평균 24.4개월의 추적관찰기간 동안 21예 중 1예의 재발이 있어, 투약기간별 재발율을 비교한 결과 6, 9, 12개월 기준별 분류에서 유의한 차이를 볼 수 있었다(p=0.012,, 0.034, 0.034). 재발군 5예와 재발이 없었던 비재발군 61예의 특성을 성별, 나이, 술전 및 술후 사용약제 수, 술전 및 술후 사용 약재분류, 약제 감수성 검사 결과, 내성 약제 수, 과거 치료력의 횟수, 수술 직전 객담배양검사 결과, 술후 투약기간, 추적관찰기간, 치료실패율 등을 비교하였는데, 이 중에 재발군에서 1예(1/5, 20%), 비재발군에서 1예(1/61, 1.6%)의 재발이 발생하여 유의한 재발율의 차이를 보였다(p<0.001). 결론 : 상기의 연구결과를 바탕으로 우리는 술후 투약 중 치료실패가 재발의 주 요인이 될 수 있음을 알 수 있었고, 과거 치료력의 수가 2이하군에서는 술후에 최소한 6개월을 초과하는 투약기간이 필요하며, 다제 내성 등을 이유로 이차 항결핵제를 사용하는 군은 술후에 최소 12개월을 초과하는 투약기간이 필요하다는 것을 알 수 있었다. 그러나, 좀더 명확한 투약기간을 확인하기 위해서 술후 잔류병변의 유무, 절제된 폐의 미생물학적, 병리조직학적인 결과, 수술 대상(Indications for operation) 등에 의한 폐절제술 후 투약기간을 공식화하는데 더 많은 연구와 분석이 있어야 하겠다.
