PURPOSE: To determine the clinical value of the Siewert classification for gastic-cancer patients in Korea, we evaluated and compared the clinicopathologic factors of type II and type III cancer. MATERIALS AND METHODS: The medical records of 89 consecutive patients who had undergone surgery for an adenocarcinoma of the gastroesophageal junction (GEJ) at the Department of Surgery, Hanyang University Hospital, between Jun. 1992 and Dec. 2003 were reviewed retrospectively. RESULTS: There were one patient with type I, 12 pateints with type II and 77 patients with type III. During the same period, 1,341 patients underwent surgery for a gastric carcinoma, so proportion of GEJ cancer being 6.6%. The median follow- up duration was 31 months (range: 2~135 months), and the follow-up rate was 100%. Between type II and type III cancers, there were no significant differences in the clinicopathologic variables including age, sex, gross appearance, histologic type, depth of invasion, and pathologic stage. The longest diameter of the tumor was larger in type III (6.1+/-2.1 cm) than in type II (3.9+/-1.1 cm)(P=0.001). A total gastrectomy with Roux-en-Y esophagojejunostomy was done most frequently, while jejunal interposition was done in 3 cases of type II and 2 cases of type III. More than a D2 lymphadenectomy was done all cases. The numbers of dissected lymph nodes and metastatic lymph nodes in type II were 43.8 and 5.8 respectively, while they were 49.8 and 8.1 in type III, but the difference between the two groups were not statistically significant. The mean length of the proximal resection margin was 15+/-5 mm in type II and 21+/-13 mm in type III, but this difference was not statistically significanct. The time to recurrence after operation was 19.3 months in type II and 16.9 months in type III. The five-year survival rates of type II and III were 68.8% and 52.7% respectively, but difference was not significant. CONCLUSION: There were no significant differences in the clinicopathologic variables, including survival rate, between type II and type III cancers in Korean patients. According to these findings, it appears to be reasonable to classify type III cancer as a cardia cancer in a broad sense.

Journal of the Korean Gastric Cancer Association 2005;5(4):288-294
PURPOSE: Superficially spreading (SS) early gastric cancer (EGC) is characterized by wide horizontal extension without deep vertical invasion. It is a relatively rare form of EGC, and it's clinicopathological (C-P) characteristics are not evident. This study aimed to clarify their C-P characteristics. MATERIALS AND METHODS: We defined SS EGC as invading less than the submucosal layer that measured more than 60 mm in diameter or wider than 5 x 5 cm (25 cm2) in width. The C-P characteristics and prognosis were compared between 69 patients with SS EGC and 319 patients with the common type EGC (EGC except SS type). RESULTS: For SS EGC, lymph node metastases, Lauren's diffuse type, lymphatic invasion were significantly higher than in common type EGC. In patients with SS EGC, all of the metastatic lymph nodes were anatomically distributed within the paragastric region, with fewer along the left gastric artery and common hepatic artery. In 6 cases of SS EGC with resection margins less than 10 mm, there was no death during the follow-up period (4 to 13 years after operation) if margins were not involved. Age (>58 yrs), tumor site (upper 1/3), lymph node metastasis, submucosal invasion were statistically significant poor prognostic factor in univariate survival analysis. In multivariate survival analysis, age and lymph node metastasis were independent prognostic factors. However, tumor diameter or width was not a significant prognostic factor. CONCLUSION: Although SS EGC has histologically distinct properties, gastrectomy with free surgical margins and appropriate lymph node dissection (D1+beta) could be a suitable treatment.

Journal of the Korean Gastric Cancer Association 2005;5(1):29-33
PURPOSE: To determine the prognostic values of the hematologic parameters checked preoperatively in gastric cancer patients, we evaluated and compared the relationship between hematologic parameters and clinicopathologic factors of gastric cancer patient. MATERIALS AND METHODS: The medical records of 357 consecutive patients who had undergone surgery for gastric cancer at the Department of Surgery, Hanyang University Hospital, between Dec. 2,000 and Dec. 2003 were reviewed. To exclude any adverse effect of invasive procedures to hematologic parameters, the samples taken immediately at outpatient department was used. The normal range of serum albumin was defined above 3.5 g/dl, serum hemoglobin above 12 g/dl, and serum platelet count under 400x10(3)/microliter. Patients were defined as group 1 when any of these parameters was abnormal, and defined as group 2 when all parameters were normal. The relationships between hematologic parameters and survival rate were investigated. RESULTS: The mean values of platelet count increased, but level of serum albumin and serum hemoglobin decreased significantly according to the advancement of the disease stage (P=0.000). The differences of depth of tumor invasion and lymph node metastasis between the group 1 and the group2 was statistically significant (P=0.001). Three-year survival difference between group 1 and group 2 was significant (P=0.037). CONCLUSION: The hematologic parameters checked preoperatively in patients of gastric cancer are simple and cheap, meanwhile reflect the general condition of the patients. Any presence of anemia, hypoalbuminemia, or thrombocytosis can predict the progression of the disease and poor survival rates.

We report a case of Mycobacterium(M.) fortuitum infection in a 65-year-old female who presented with erythematous to purplish colored tender nodules and plaques with curst and purulent discharge on both upper and lower extremities along the sites of acupuncture. The culture of surgically excised specimen in 3% Ogawa media yielded slightly yellowish colored colonies within 2 days. Several tests for identification of the species were performed and growth on 5% NaCl, negative niacin test, positive results in nitrate reduction, catalase, urease and iron uptake tests were noted. Excision of the lesions followed by administration of minocycline and ciprofloxacin showed no sign of relapse to data a year after treatment.

BACKGROUND: The criteria for defining sarcopenia vary among studies and confusion has arisen when defining the cutoff value. As a result, the prevalence of sarcopenia differs markedly depending on the definition. This study used the Asian Working Group for Sarcopenia (AWGS) definition to determine the prevalence of sarcopenia among Korean women. METHODS: This study was based on data obtained from the 2008 to 2011 Korean National Health and Nutrition Examination Surveys IV and V. We used the AWGS recommended cutoff value of 5.4 kg/m2 to determine the prevalence of sarcopenia in Korean women. RESULTS: The prevalence rates of sarcopenia using a cutoff value of 5.4 kg/m2 were 385 (19.5%) in women in their 50s, 286 (16.6%) in women in their 60s, 293 (23.7%) in women in their 70s, and 91 (30.8%) in women > or =80 years. The prevalence rates of sarcopenia were 307 (19.0%) in women 65 to 74 years, 194 (27.4%) in women 75 to 84 years, and 32 (40.5%) in women > or =85 years. The overall prevalence among women >50 years was 20.2%. The prevalence of sarcopenia in women >65 years was 22.1%. CONCLUSIONS: The prevalence of sarcopenia among Korean women was within the range of values of previous research about sarcopenia. Furthermore, using 5.4 kg/m2 as the cutoff value was useful to compare various studies about sarcopenia in Koreans.

Journal of Bone Metabolism 2015;22(2):71-75
BACKGROUND: Sarcopenia is considering important disease entity in elderly. Several study groups define the sum of the muscle masses of the four limbs as appendicular skeletal mass (ASM) to calculate skeletal muscle index (SMI). The purpose of this study was to determine cut point of SMI for sarcopenia in Korean women. METHODS: This study was based on data obtained from the 2008 to 2011 Korean National Health and Nutrition Examination Survey (KNHANES) IV and V. A whole body dual energy X-ray absorptiometry scan were performed on individuals of > or =10 years old from July 2008 to May 2011. In the analysis, 11,633 women were included. ASM was calculated and SMI was obtained as ASM/height2. Cutoff value was defined two standard deviations below mean values for young reference group. RESULTS: Of 11,633 women aged 10 to 97 years, mean and standard deviation of year was 46.73+/-18.54 years. The highest level of height was noted in 20's and the highest total sum of skeletal mass was seen 14.87 kg in 40's. The highest value of SMI was noted in 60's in Korean women. Cutoff value as mean value of young women was decided with SMI of 30's and 40's that have peak ASM. Mean and standard deviation of SMI in those ages was 5.9+/-0.7 kg/m2. A SMI of two standard deviations below the mean SMI of reference groups was 4.4 kg/m2 as cutoff value. CONCLUSIONS: This study shows that 4.4 kg/m2 of SMI in Korean women was cutoff value of sarcopenia. Further study is clearly required to decide cutoff value of SMI for sarcopenia, especially for Korean women.

Journal of the Korean Gastric Cancer Association 2005;5(3):174-179
PURPOSE: The 5-year survival rate is the most useful parameter for evaluating the effect of management on most malignant tumors. Recurrence after a curative resection for gastric cancer occurs mostly within 3 years of the operation, which caused us to evaluate whether a 3-year disease-free survival (3DFS) can be substituted for a 5-year overall survival (5OS). MATERIALS AND METHODS: We reviewed the medical records of 656 consecutive patients who had undergone a curative resection for gastric cancer. To assess whether 3DFS represents 5OS, we used a simple linear regression with survival probability calculated by using the survival function. RESULTS: Recurrence was found in 175 cases during the follow-up periods. The accumulative frequencies of recurrence at postoperative 1 year, 3 years, and 5 years were 46% (81 cases), 89% (156 cases), and 97% (170 cases), respectively. The correlation coefficient (r) and the coefficient of determination (r2) between 3DFS and 5OS were 0.87 and 0.76, respectively, and the regression equation was 5OS=0.18+(0.80 x 3DFS). The r and R2 according to the type of recurrence were 0.89 and 0.80 in peritoneal seeding, 0.88 and 0.78 in hematogeneous metastasis, and 0.86 and 0.73 in local recurrence, respectively. The r (0.77) and r2 (0.60) were relatively lower in low stages (stage I and II) compared to r (0.88) and r2 (0.77) in high stages (stage III and IV). CONCLUSION: The 3DFS is an excellent predictor of 5OS. Therefore, if we use the former as the treatment evaluating method, 2-year time reduction in assessing and reporting treatment results is expected.

To clarify the clinicopathologic features of small-cell carcinomas (SCC) of the stomach, we reviewed three cases of surgically treated SCC. The first case was a pure SCC, with severe pancreatic invasion and peritoneal seeding. A gastro-jejunostomy was performed. Postoperative chemotherapy was performed with CDDP and VP-16 (8 cycles), but showed disease progression (PD); a consecutive chemotherapy with CDDP and irinotencan (2 cycles) also showed PD. A third line with CDDP, VP16, ifosfamide, and mesna was followed by a 4th line (CDDP and Taxol). The male patient died with liver metastasis and peritoneal seeding 14 months after the operation. The second case was a SCC mixed with a poorly differentiated adenocarcinoma. Profound lymphadenopathy and liver metastasis were found. Two cycles of preoperative chemotherapy with TS-1 and CDDP were performed, which showed nearly complete remission for lymphadenopathy and partial response for the primary tumor site and liver metastatic lesion. A total gastrectomy and extended lymphadenectomy was performed. There were no viable cancer cells in 35 retrieved lymph nodes. Postoperative chemotherapy using the same regimen was performed for 4 cycles. Enlarged liver metastasis was found at the follow-up CT scan, so a posterior segmentectomy of liver was performed. After liver surgery, the chemotherapy regimen was changed to irinotecan and cisplatin. This male patient has been in good health for the 14 months since gastric surgery. The third case was a pure SCC, and a subtotal gastrectomy was performed curatively. That male patient received 5 cycles of TS-1 and is still in good health 14 months after operation.
