  • 배경: 최근 식도암의 성적을 향상시키려는 노력들이 행하여지고 있고 수술 성적도 많이 보고되고 있으나 아 직 국내에서는 많은 수의 환자를 대상으로 한 장기 성적은 드문 형편이다. 이 연구에서는 지난 13년간 서울 대학교병원 흉부외과에서 치험한 식도암 환자를 대상으로 후향적으로 연구하여 장기 생존율을 분석하여 향 후 전향적 연구의 기초로 삼고자 하였다. 대상 및 방법: 1984년부터 1996년까지 서울대학교 병원에서는 총 734명의 환자가 식도암으로 진단 받았으며 이들 환자 중 식도 절제가 가능하였던 253례의 환자를 대상으로 종양의 병기별 생존율을 후향적으로 분석하였다. 결과: 식도암의 세포형은 편평상피세포암이 237례로 대부 분을 차지하였고, 선암이 6례, 선암-편평상피암 5례, 소세포암3례, 기타 흑색포암 등이 있었다. 종양의 병기는 상피내 암종 4례, 1기가 21례, 2A기가 79례, 2B기가 30례, 3기 107례, 4기 6례 있었고, 6례에서는 병기를 확인 할 수 없었다. 수술 사망은 14례 (5.5%) 있었고 그 원인은 폐렴에 의한 호흡부전이 8례로 가장 많았고, 그 밖 에 패혈증, 급성 간부전, 과다 출혈 등이 있었다. 수술 후 일부 환자에서는 보조적 방사선 치료를 시행하였으 며, 재발한 경우에는 화학요법이나 방사선 치료를 시행하였다. 수술 사망 환자를 제외한 장기 생존자 중 근 치적 절제가 가능했던 222명 환자의 생존율은 1년 74.7$\pm$3.1%, 2년 46.5$\pm$3.7%, 3년 32.3$\pm$3.7%, 5년 19.9$\pm$3.3% 이었다. 결론: 이상의 결과로부터 식도암에 대한 외과적 절제술은 비교적 낮은 수술 사망률로 시행할 수 있으나 장기 생존율은 아직 낮아 향후 화학요법 혹은 방사선 요법 등을 병합하여 치료하는 등의 새로운 치료법에 대한 연구가 시급하다고 판단되었다.

  • 목적: 신 이식 이틀째 촬영한 Tc-99m DTPA 스캔 소견에서 나타난 이식신의 기능 저하가 이식신의 장기 생존에 영향을 미치는 지 알아보았다. 대상 및 방법: 생체 신 이식 총 64예에서 신장 스캔 소견에 따른 이식신 누적 생존율의 차이를 Kaplan-Meier법으로 분석하고, Cox proportional hazard model을 이용하여 이식신 장기 생존율 예측능을 알아보았다. Chi-square test로 두 군 간에 급성 거부반응의 빈도 차이를 보았다. 결과: 신장 스캔 비정상군의 이식신 장기 생존율이 정상군에 비하여 낮았으나 그 차이가 통계적으로 유의하지 않았다. 이식 직후 신장 스캔 소견 상 나타나는 이식신 기능저하도 이식신 장기 생존의 예후 인자가 아니었다. 단, 신장 스캔 비정상군에서 급성 거부 반응 빈도가 정상군에 비하여 유의하게 높았다. 결론: 생체 신이식 예에서 이식 직후 신장 스캔에서 이식신의 기능 저하 소견은 이식신의 장기 생존에 직접적 영향은 없으나 급성 거부 반응을 증가시켜 간접적 영향이 있을 것으로 판단된다.

  • Background: In 2008, Korea implemented a new type of social insurance known as "long-term care insurance". We examined the association between ownership of long-term care facilities and the incidence of pressure ulcers after the implementation of "long-term care insurance". This study is a population-based retrospective cohort study from 2006 to 2013. Methods: We used medical claims data from the Korean National Health Insurance Corporate Elderly Cohort Database from 2006 to 2013. These data comprise a nationally representative sample. To avoid confounders, only patients admitted to one long-term care facility and who stayed for >70% of the follow-up time were included; as a result, 3,107 individuals were enrolled. The main independent variable was the operating entity of the long-term care facility (local government, corporate bodies, and private for-profit owners), and the dependent variable was the 1-year incidence of pressure-ulcers. Survival analysis (Cox proportional hazard model) was used as an analysis method. Results: Compared to patients admitted to local government long-term care facilities, patients admitted to private long-term care facilities had a significantly higher 1-year risk of pressure ulcers (hazard ratio [HR], 1.94; 95% confidence interval [CI], 1.29-2.91); the risk was especially high among patients who were cognitively dependent (HR, 2.34; 95% CI, 1.25-4.37). Conclusion: Patients admitted to private for-profit long-term care facilities were more likely to have pressure ulcers compared to those in local government and corporate body long-term care facilities. Appropriate assessment tools and publicly available information, as well as more restricted legal requirements, are needed to improve the care quality and outcomes of patients in long-term care facilities.

  • Background: This study evaluated the early and long-term outcomes of surgical aortic valve replacement (AVR) in elderly patients in the era of transcatheter aortic valve implantation. Methods: Between 2001 and 2018, 94 patients aged ${\geq}75years$ underwent isolated AVR with stented bioprosthetic valves for aortic valve stenosis (AS). The main etiologies of AS were degenerative (n=63) and bicuspid (n=21). The median follow-up duration was 40.7 months (range, 0.6-174 months). Results: Operative mortality occurred in 2 patients (2.1%) and paravalvular leak occurred in 1 patient. No patients required permanent pacemaker insertion after surgery. Late death occurred in 11 patients. The overall survival rates at 5 and 10 years were 87.2% and 65.1%, respectively. The rates of freedom from valve-related events at 5 and 10 years were 94.5% and 88.6%, respectively. The Society of Thoracic Surgeons (STS) score (p=0.013) and chronic kidney disease (p=0.030) were significant factors affecting long-term survival. The minimal p-value approach demonstrated that an STS score of 3.5% was the most suitable cut-off value for predicting long-term survival. Conclusion: Surgical AVR for elderly AS patients may be feasible in terms of early mortality and postoperative complications, particularly paravalvular leak and permanent pacemaker insertion. The STS score and chronic kidney disease were associated with long-term outcomes after AVR in the elderly.

  • Background: Although the Cox's proportional hazard model is the popular approach for survival analysis to investigate significant risk factors of cancer patient survival, it is not appropriate in the case of log-term disease free survival. Recently, cure rate models have been introduced to distinguish between clinical determinants of cure and variables associated with the time to event of interest. The aim of this study was to use a cure rate model to determine the clinical associated factors for cure rates of patients with breast cancer (BC). Materials and Methods: This prospective cohort study covered 305 patients with BC, admitted at Shahid Faiazbakhsh Hospital, Tehran, during 2006 to 2008 and followed until April 2012. Cases of patient death were confirmed by telephone contact. For data analysis, a non-mixed cure rate model with Poisson distribution and negative binomial distribution were employed. All analyses were carried out using a developed Macro in WinBugs. Deviance information criteria (DIC) were employed to find the best model. Results: The overall 1-year, 3-year and 5-year relative survival rates were 97%, 89% and 74%. Metastasis and stage of BC were the significant factors, but age was significant only in negative binomial model. The DIC also showed that the negative binomial model had a better fit. Conclusions: This study indicated that, metastasis and stage of BC were identified as the clinical criteria for cure rates. There are limited studies on BC survival which employed these cure rate models to identify the clinical factors associated with cure. These models are better than Cox, in the case of long-term survival.

  • The aim of this study was to determine the condition of supportive periodontal therapy (SPT) in implant patients and the effect of SPT on implant long-term survival. Implants placed at the Dept. of Periodontology, Chonnam National University Dental Hospital over a 5-year period, were traced for up to 8 years. Patients who had visited the hospital at least once a year were defined as regular SPT, and patients who were treated by active periodontal therapy were defined as patients with periodontitis. Kaplan-Meier survival analysis was performed based on the observation periods, and the effect of SPT and history of periodontitis on implant survival assessed by chisquare test. A total of 183 patients (age: 21-91, 98 males and 85 females), and 508 implants were used for this study. Three hundred eight implants were under SPT and 87 implants was under regular SPT. For the patients with periodontitis 136 implants were placed. The 5-year survival rate was 94.8%. The overall survival rate in patients who received SPT was 97.1% and 91.0% for those who did not (p=0.004). The survival rate in patients who received regular SPT was 97.7%, and 96.8% for patients received irregular SPT. The survival rate was 93.4% in patients with periodontitis and 95.2% in patients without periodontitis. Among patients with periodontitis, the survival rate was 100.0% in patients who received regular SPT and 89.2% for irregular SPT (p=0.012). These results suggest that regular SPT improves implant survival rate and is more effective in patients with periodontitis.

  • Purpose: The prognosis of stage IV gastric cancer is very grave. However, some of these patients survive long periods after surgery. This study was undertaken to investigate various clinico-pathological profiles related to the prognosis for these long-term survivors. Materials and Methods: One hundred fifty-five patients with stage IV gastric cancer who underwent a gastric resection from 1992 to 1997 at Hanyang University Hospital were evaluated. Thirty-three patients who survived more than 5 years after surgery were designated as long-term survivors (LTS); on the other hand, one hundred twenty-two patients who died within 5 years after surgery were named as short-term survivors (STS). Results: The rate of the patients with T4, preoperative serum level of CA19-9 greater than 37 U/g protein, and peritoneal dissemination was lower for the LTS than in for the STS (P=0.002, P=0.045, and P=0.0000, respectively). Tumors were smaller (7.3 cm vs. 8.9 cm, P=0.030) and metastatic lymph node were fewer (19.7 vs. 28.8, P=0.019) for the LTS than for the STS. Curative surgery ($\76\%\;vs.\;\46\%$, P=0.002) and a subtotal gastrectomy ($\76\%\;vs.\;46\%$, P=0.026) were performed more frequently for the LTS than for the STS. From a univariate survival analysis, depth of invasion, distant metastasis, extent of gastric resection, postoperative chemotherapy, and curability were statistically significant factors. From a multivariate survival analysis, curability, depth of invasion, and extent of gastric resection were independent prognostic factors. Conclusions: If feasible, we have to exert our efforts to achieve curative surgery although the tumor is considered to be a stage IV gastric cancer. Thereafter, multi-modality treatments including chemotherapy can be considered to improve the prognosis.
