Background: Patients on dialysis undergoing surgery belong to a high-risk group. Only a few studies have evaluated the outcome of major thoracic surgical procedures in dialysis patients. We evaluated the outcomes of pulmonary resection for non-small cell lung cancer (NSCLC) in patients on hemodialysis (HD). Methods: Between 2008 and 2013, seven patients on HD underwent pulmonary resection for NSCLC at our institution. We retrospectively reviewed their surgical outcomes and prognoses. Results: The median duration of HD before surgery was 55.0 months. Five patients underwent lobectomy and two patients underwent wedge resection. Postoperative morbidity occurred in three patients, including pulmonary edema combined with pneumonia, cerebral infarction, and delirium. There were no instances of in-hospital mortality, although one patient died of intracranial bleeding 15 days after discharge. During follow-up, three patients (one patient with pathologic stage IIB NSCLC and two patients with pathologic stage IIIA NSCLC) experienced recurrence and died as a result of the progression of the cancer, while the remaining three patients (with pathologic stage I NSCLC) are alive with no evidence of disease. Conclusion: Surgery for NSCLC in HD patients can be performed with acceptable perioperative morbidity. Good medium-term survival in patients with pathologic stage I NSCLC can also be expected. Pulmonary resection seems to be the proper treatment option for dialysis patients with stage I NSCLC.

수질의 형질세포종(extramedullary plasmacytoma)은 극히 드물게 나타나는 형질세포 악성종양(plasma cell malignancy)중 하나이며 치은에 발생한 경우는 거의 보고된바 없다. 다발성 골수종과의 감별진단은 조직학적 검사 후에도 여러 혈액검사 및 병이화학 검사가 필요하며 초기진단에 확실한 검사는 어렵다. Pahor등에 의하면 수질외 형질세초종의 5년생존률이 60%인 것에 비해 다발성 골수종에서는 5.7%를 보여 예후에 있어서 현저한 차이를 보이고 보든 수질외 형질세포종환자에 있어서 전신질환으로의 진행 가능성은 배제할 수 없으므로 장기간의 관찰이 필수적이라고 할 수 있다. 저자 등은 신장이식 수술 후 면역억제제를 사용한 15세 환자에서 치은에 발생한 형질세포을 치험하였기에 문헌 고찰과 함께 진단, 예후, 치료 및 면역 억제제와의 연관성에 관하여 보고하는 바이다.

Objectives: Metabolic syndrome is a cluster of risk factors for type 2 diabetes mellitus and cardiovascular disease. Associations between metabolic syndrome and several types of cancer have recently been documented. Methods: We analyzed the sample cohort data from the Korean National Health Insurance Service from 2002, with a follow-up period extending to 2013. The cohort data included 99 565 individuals who participated in the health examination program and whose data were therefore present in the cohort database. The metabolic risk profile of each participant was assessed based on obesity, high serum glucose and total cholesterol levels, and high blood pressure. The occurrence of cancer was identified using Korean National Health Insurance claims data. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using Cox proportional hazards models, adjusting for age group, smoking status, alcohol intake, and regular exercise. Results: A total of 5937 cases of cancer occurred during a mean follow-up period of 10.4 years. In men with a high-risk metabolic profile, the risk of colon cancer was elevated (HR, 1.40; 95% CI, 1.14 to 1.71). In women, a high-risk metabolic profile was associated with a significantly increased risk of gallbladder and biliary tract cancer (HR, 2.05; 95% CI, 1.24 to 3.42). Non-significantly increased risks were observed in men for pharynx, larynx, rectum, and kidney cancer, and in women for colon, liver, breast, and ovarian cancer. Conclusions: The findings of this study support the previously suggested association between metabolic syndrome and the risk of several cancers. A high-risk metabolic profile may be an important risk factor for colon cancer in Korean men and gallbladder and biliary tract cancer in Korean women.

Purpose: Various changes in nutrition, metabolism, immunity, and psychological status occur through multiple mechanisms after gastrectomy. The purpose of this study was to predict disease status after gastrectomy by analyzing diseases pattern that occur or change after gastrectomy. Materials and Methods: A retrospective cohort study was conducted using nationwide claims data. Patients with gastric cancer who underwent gastrectomy or endoscopic resection were included in the study. Eighteen target diseases were selected and categorized based on their underlying mechanism. The incidence of each target disease was compared by dividing the study sample into those who underwent gastrectomy (cases) and those who underwent endoscopic resection for early gastric cancer (controls). The cases were matched with controls using propensity score matching. Thereafter, Cox proportional hazard models were used to evaluate intergroup differences in disease incidence after gastrectomy. Results: A total of 97,634 patients who underwent gastrectomy (84,830) or endoscopic resection (12,804) were included. The incidence of cholecystitis (P<0.0001), pancreatitis (P=0.034), acute kidney injury (P=0.0083), anemia (P<0.0001), and inguinal hernia (P=0.0007) were higher after gastrectomy, while incidence of dyslipidemia (P<0.0001), vascular diseases (ischemic heart disease, stroke, and atherosclerosis; P<0.0001, P<0.0001, and P=0.0005), and Parkinson's disease (P=0.0093) were lower after gastrectomy. Conclusions: This study identifies diseases that may occur after gastrectomy in patients with gastric cancer.

발생률이 높고, 예후는 좋지만 재발을 잘하는 경향이 있는 갑상선암에서도 전통적인 치료법은 수술이다. 하지만, 2000년대 초반부터, 간암, 폐암, 신장암에서와 마찬가지로 고주파 절제술이 원발 갑상선암 및 재발 갑상선암에 적용되기 시작했다. 원발암에서는 1 cm 이하 크기의 미세유두암 저위험군에서 수술 불가능한 경우에 대한 많은 연구가 이뤄져 왔고, 1 cm보다 더 크고 4 cm 이하의 다양한 군에 대해서도 일부 연구가 시행되었으며, 전반적으로 모두 양호한 결과를 보고하였다. 재발암에 대해서도 주로는 국소 경부 재발암에 고주파 절제술이 시행되었으며, 일부 폐, 뼈 등의 원격 전이에 대해서도 시도되었고, 전반적으로 양호한 결과가 보고되었다. 최근 들어, 한국, 미국, 유럽 등 각지에서 갑상선암의 고주파 절제술에 대해 옹호하는 움직임이 있다. 하지만, 미국 국립 종합 암 네트워크(National Comprehensive Cancer Network) 등의 중립적인 임상지침에는 고주파 절제술이 아직 인정되지는 않은 상태이다. 지금까지의 노력들과 미래의 연구를 바탕으로 향후 가까운 미래에 갑상선암의 치료에 있어 고주파 절제술이 적절한 자리매김을 할 것으로 전망한다.

Purpose: The surgical outcomes of end-stage renal disease (ESRD) patients undergoing radical gastrectomy for gastric cancer were inferior compared with those of non-ESRD patients. This study aimed to evaluate the short- and long-term surgical outcomes of ESRD patients undergoing laparoscopic gastrectomy (LG) and open gastrectomy (OG) for gastric cancer. Materials and Methods: Between 2004 and 2014, 38 patients (OG: 21 patients, LG: 17 patients) with ESRD underwent gastrectomy for gastric cancer. Comparisons were made based on the clinicopathological characteristics, surgical outcomes, and long-term survival rates. Results: No significant differences were noted in the clinicopathological characteristics of either group. LG patients had lower estimated blood loss volumes than OG patients (LG vs. OG: 94 vs. 275 mL, P=0.005). The operation time and postoperative hospital stay were similar in both the groups. The postoperative morbidity for LG and OG patients was 41.1% and 33.3%, respectively (P=0.873). No significant difference was observed in the long-term overall survival rates between the 2 groups (5-year overall survival, LG vs. OG: 82.4% vs. 64.7%, P=0.947). Conclusions: In ESRD patients, LG yielded non-inferior short- and long-term surgical outcomes compared to OG. Laparoscopic procedures might be safely adopted for ESRD patients who can benefit from the advantages of minimally invasive surgery.

14살령의 중성화 수컷 개가 혈뇨와 배뇨통으로 내원하였다. 복부초음파 검사에서 편측성 수신증과 요관 벽이 국소적으로 두꺼워진 수뇨관증이 진단되었다. 수술적 탐색으로 좌측 근위 요관에서 요관 유래의 관내 종괴가 확인되었으며, 종괴 절제술이 실시되었다. 요관 종괴는 조직학적 검사를 통해 유두상 이행세포암종으로 진단되었다. 환자는 안정적으로 회복되었으나, 수술 3개월 후 또 다른 종괴가 우측 신장에서 발견되었다. 신장 종괴에 대한 세포학적 검사 결과 간엽세포종양으로 진단되었다.

신장의 혈관근지방종은 전형적으로 고형 종괴지만, 낭성 형태의 신장 혈관근지방종이 소수 보고되었다. 그중에서 대다수의 보고는 상피낭종을 동반한 혈관근지방종으로 입방상피조직으로 둘러싸인 낭종을 포함한다. 다음으로 상피모양 혈관근지방종은 호산성 세포질이 풍부한 상피모양세포를 포함하는데, 이것이 출혈이나 괴사로 인해 낭성변화를 일으킨 증례 보고도 있었다. 이런 낭성 형태의 신장 혈관근지방종은 영상검사에서 낭성 신세포암 등의 다른 낭성 종괴로 오인될 수 있다. 이 증례 보고에서는 58세 남성에서 발견된 상피낭종을 동반한 상피모양 혈관근지방종의 영상 소견을 살펴보려고 한다.
