The Surgery Treatment Modality Committee of the Korean Gynecologic Oncologic Group (KGOG) has determined to develop a surgical manual to facilitate clinical trials and to improve communication between investigators by standardizing and precisely describing operating procedures. The literature on anatomic terminology, identification of surgical components, and surgical techniques were reviewed and discussed in depth to develop a surgical manual for gynecologic oncology. The surgical procedures provided here represent the minimum requirements for participating in a clinical trial. These procedures should be described in the operation record form, and the pathologic findings obtained from the procedures should be recorded in the pathologic report form. Here, we focused on radical hysterectomy and lymphadenectomy, and we developed a KGOG classification for those conditions.

PURPOSE: The management of central venous catheters (CVCs) and catheter thrombosis vary among centers, and the efficacy of the methods of management of catheter thrombosis in CVCs is rarely reported. We investigated the efficacy of bedside thrombolysis with urokinase for the management of catheter thrombosis. MATERIALS AND METHODS: We retrospectively reviewed data from patients who had undergone CVC insertion by a single surgeon in a single center between April 2012 and June 2014. We used a protocol for the management of CVCs and when catheter thrombosis was confirmed, 5,000 U urokinase was infused into the catheter. RESULTS: A total of 137 CVCs were inserted in 126 patients. The most common catheter-related complication was thrombosis (12, 8.8%) followed by infection (8, 5.8%). Nine of the 12 patients (75%) with catheter thrombosis were recanalized successfully with urokinase. The rate of CVC recanalization was higher in the peripherally inserted central catheter (PICC) group (87.5%) than the chemoport group (50%). Reintervention for catheter-related thrombosis was needed in only 2.2% of patients when thrombolytic therapy using urokinase was applied. Age <60 years (P=0.035), PICC group (P=0.037) and location of the catheter tip above the superior vena cava (P=0.044) were confirmed as independent risk factors for catheter thrombosis. CONCLUSION: Thrombolysis therapy using urokinase could successfully manage CVC thrombosis. Reintervention was rarely needed when a protocol using urokinase was applied for the management of CVC thromboses.

BACKGROUND: Absolute lymphocyte count (ALC) in peripheral blood has recently been reported to be an independent prognostic factor in multiple myeloma (MM). Previous studies indicated that the absolute monocyte count (AMC) in peripheral blood reflects the state of the tumor microenvironment in lymphomas. Neither the utility of the AMC nor its relationship with ALC has been studied in MM. METHODS: The prognostic value of ALC, AMC, and the ALC/AMC ratio at the time of diagnosis was retrospectively examined in 189 patients with MM. RESULTS: On univariate analysis, low ALC (<1,400 cells/microL), high AMC (> or =490 cells/microL), and low ALC/AMC ratio (<2.9) were correlated with worse overall survival (OS) (p=.002, p=.038, and p=.001, respectively). On multivariate analysis, the ALC/AMC ratio was an independent prognostic factor (p=.047), whereas ALC and AMC were no longer statistical significant. Low ALC, high AMC, and low ALC/AMC ratio were associated with poor prognostic factors such as high International Staging System stage, plasmablastic morphology, hypoalbuminemia, and high beta2-microglobulin. CONCLUSIONS: Univariate analysis demonstrated that changes in ALC, AMC, and the ALC/AMC ratio are associated with patient survival in MM. Multivariate analysis showed that, of these factors, the ALC/AMC ratio was an independent prognostic factor for OS.

OBJECTIVE: To retrospectively compare the imaging characteristics of retropharyngeal density and associated findings for Kawasaki disease with those for non-Kawasaki disease, and identify the distinguishing features which aid the CT diagnosis of Kawasaki disease with retropharyngeal low density. MATERIALS AND METHODS: Among the enhanced neck CT performed in children less than 8-years old with clinical presentation of fever and cervical lymphadenopathy over a 6-year period, only cases with retropharyngeal low density (RLD) were included in this study. The 56 cases of RLD were divided into two groups; group A included cases diagnosed as Kawasaki disease (n = 34) and group B included cases diagnosed as non-Kawasaki disease (n = 22). We evaluated the CT features including the thickness of RLD and its extent into the deep neck spaces, as well as soft tissue change in the adjacent structure. We also scored the extent of RLD into the deep neck spaces and the soft tissue changes in the adjacent structure. RESULTS: The thickness of RLD was greater in group A than in group B (group A, 6.0 +/- 2.1; group B, 4.6 +/- 1.5, p = 0.01). The score of the RLD extent into the deep neck spaces was significantly greater in group A than in group B (group A, 2.3 +/- 1.3; group B, 0.8 +/- 1.0, p < 0.01). Also, the score of the adjacent soft tissue changes was greater in group A than in group B (group A, 2.0 +/- 1.1; group B, 1.0 +/- 1.0, p < 0.01). CONCLUSION: If children present with fever and cervical lymphadenopathy that display retropharyngeal low density with extension into more deep neck spaces as well as changes in more adjacent soft tissue, the possibility of Kawasaki disease should be considered.

BACKGROUND: Although several hospital-based stroke studies were published, there has not been any reliable data representing the clinical characteristics of stroke in Korea. We analyzed the clinical characteristics of patients with ischemic stroke registered in the Korean Stroke Registry (KSR), which is the largest prospective hospital-based nation-wide stroke registry in Korea. METHODS: The KSR provided standardized protocols for collecting data, which includes the data of demographics, subtypes of stroke, risk factors, and neurological outcome at discharge. The brain imaging studies, including CT or MRI, were performed in all cases. RESULTS: KSR registered 10,811 patients of acute ischemic stroke between Nov. 2002 and Jun. 2004. The large-artery atherosclerosis was the most common subtype (37.3%), followed by small vessel occlusion (30.8%). Hypertension (65.4%) was the most common risk factor, followed by smoking (34.5%) and diabetes (28.3%). Although most of the hypertensive and diabetic patients had been diagnosed before the stroke, less than 45.4% and 32.5% of them were under regular control. The steno-occlusive lesion of extracranial carotid artery was only 29.3% and the ratio of intra- to extracranial artery disease was more than 2 in KSR. Only 20.5% of patients were admitted within 3 hours after stroke onset and 2.1% were treated with intravenous thrombolysis. In-hospital case-fatality was 5.2%, which is relatively comparable to those of previous studies. CONCLUSIONS: The KSR provided informative data in understanding the clinical characteristics of ischemic stroke in Korea. Further analysis of KSR will facilitate clinical trials and development of guidelines for the management of stroke patients.

Aortic thrombus is a rare but life threatening disorder. The usual causes of aortic thrombus are primary or secondary thrombocythemia, malignancy, atherosclerosis, trauma, and acute infectious disease. Here, we report a case of aortic arch thrombus associated with acute pyelonephritis in a patient with thrombocythemia. A 78-year-old woman was admitted with acute pyelonephritis. A complete blood cell count showed severe thrombocythemia with platelet count of 1, 340, 000/mm3. Chest CT scan demonstrated floating thrombus in the aortic arch. After antibiotic treatement, platelet count decreased to 770, 000/mm3 and aortic thrombus disappeared without thrombolytic therapy.

BACKGROUND: The primary mediastinal lymphoma (PML) is defined as the non-Hodgkin's lymphoma that presents primarily within the mediastinum, and primary mediastinal diffuse large B cell lymphoma (PMLBL) is defined as primary mediastinal lymphoma of which histology shows diffuse large B cell lymphoma. There is no available clinical study yet about the clinical characteristics and treatment outcome of PMLBL in Korea. Here the authors report our experience of 21 cases of PML including 11 cases of PMLBL. METHODS: The authors reviewed retrospectively medical records of 21 cases with PML from January 1992 to January 2003, and analyzed clinical characteristics, response to induction therapy, and survival. The authors subsequently performed subset analysis in 11 cases with PMLBL. Median follow-up period was 16 months (range, 4~80 months). RESULTS: Male to female ratio was 8:13 and the median age of 21 PML cases was 33.5 years. Of 21 PML cases, histology of most cases was diffuse large B cell lymphoma (11/21) and lymphoblastic lymphoma (8/21). Cell lineage was B cell in 13 cases (61.9%). Thirteen cases (62.0%) were in stage I and II. Initial induction therapy was chemotherapy alone in 19 cases, combined chemoradiotherapy in 1 case and no treatment in remaining 1 case. Response rate to initial therapy was 70% in 20 PML cases (complete response [CR] 50%, partial response 20%) with CR of 50% in 10 PMLBL. Median progression-free survival and overall survival for 11 PMLBL cases were 11 months and 16 months, respectively. CONCLUSION: Incidence of PML showed slight predominance in female and in relatively young age with median age of less than 40 years. Most patients presented with a chief complaint of superior vena cava syndrome including dyspnea. The most common histology of PML was diffuse large B cell lymphoma. PMLBL represented low complete response rate to conventional chemotherapy, low progression-free and overall survival rates compared with peripheral diffuse large B cell lymphoma by historical review.

PURPOSE: Proteinuria is the hallmark of glomerular injury and results from alterations in glomerular permeability. The permeability of diseased glomerulus has been estimated by selectivity of proteinuria. Recently, some authors showed a significant relationship between selectivity of proteinuria and tubulointerstial damage. The present study examines the role of protein selectivity as a prognostic marker in patients with IgA nephropathy and its correlation with other prognostic indices. METHODS: The selective proteiuria index of 81 cases with IgA nephropathy diagnosed between 1990 and 2000 were reviewed, and each case was subclassified using the following : highly selective(SPI0.2). The mean age of the patients was 27+/-15 years with a follow-up period of 38+/-24 months. Six patients had highly selective proteinuria, thirty three patients had moderately selective proteinuria, and forty two patients had nonselective proteinuria. RESULTS: 1) A significant relationship was found between the SPI and Haas subclasess(p=0.01). With respect to clinical presentaion, hypertension(0, 4, 11 cases, p<0.05), proteinuria(0.52+/-0.35, 1.85+/-1.55, 2.79+/-2.51 g/day, p<0.05) were significant correlation.2) Chronic renal failure was significantly higher in patients with nonselective proteinuria in comparison with patients with selective proteinuria(p<0.05).3) Markers of renal failure by the Cox proportional hazards model were Cr(Exp(B)=4.2, p<0.001), Ccr (Exp(B)=2.1, p<0.05), SPI(Exp(B)=1.7, p<0.05), hypertension(Exp(B)=1.6, p<0.05). 4) In 28 patients of IgA nephropathy with nephrotic syndrome, 9 patients were moderately selective, 19 patients were nonselective. The response to therapy, evaluated retrospectively, was 67% and 16% in moderate and nonselective proteinuria(p=0.01). CONCLUSION: There is a significant relationship between selectivity of proteinuria and clinical para meters. Moreover, the selectivity of proteinuria has a predictive value on functional outcome.

Mucoepidermoid carcinoma is a common malignant tumor of the salivary glands, but rare in other sites. Only 10 cases of mucoepidermoid carcinoma of liver have been reported, and there was 1 case of double primary cancer of hepatocellular carcinoma and mucoepidermoid carcinoma. The definite diagnosis and pathogenesis are still controversial. However, hepatocellular carcinoma is the second most common cancer in Korea. Its etiology is better known compared to mucoepidermoid carcinoma. We report a rare case of double primary cancer of mucoepidermoid carcinoma and hepatocellular carcinoma in liver.

OBJECTIVES: This study was performed to survey worker's demands for worksite medical care and agency's intention for offering worksite medical care in Group Health Service Agency. METHODS: One study subjects were employers, workers and office personnels in 167 factories. They were asked for medical care utilization behavior and worksite medical care demand. 121 employers(72.5%), 145 office personnels(86.8%) and 816 workers(60.5%) answered the questionnaire. The other subjects were doctors, nurses and administrators in 66 Group Health Service Agencies nationwide. They were asked for intention of offering worksite medical care in Group Health Service Agency through the mail survey. 31 doctors(47.0%), 38 nurses(57.6%) and 34 administrators answered the questionnaire. RESULTS: 87 percentage of doctors and 94 percentage of nurses had experiences of being requested to prescribe and laboratory examination. All nurses, 94 percentage of administrators and 76 percentage of doctors thought that it was necessary to give medical treatment at worksite. Also in worksite 85 percentage of employers, 86 percentage of office personnels and 81 percentage of workers answered that they accepted the worksite medical care when it would be given. CONCLUSIONS: Worksite medical care should be permitted because almost of all workers and employers requested worksite medical care, and doctors and nurses in Group Health Service Agency were willing to give worksite medical care and there was necessity to prevent occupational cerebrovascular disease.
