The antimutagenic effect of green-ye1low vegetables on the mutagenicities induced by N-methyl-N'-nitro-N-nitrosoguanidine(MNNG) and N-nitrosodimethylamine (NDMA) in Salmonella assay system and also their inhibitory effect on AZ-521 human gastric cancer cells were studied. Twenty-four items from twenty six kinds of vegetables(92%) revealed antimutagenic activity toward MNNG (p< 0.0l, 0.05). Perilla leaf, Korean cabbage, cauliflower, lettuce, mustard leaf, water dropwort, small water dropwort, carrot and burdock inhibited the mutagenicity more than 80%. The methanol extracts of the vegetables also showed the antimutagenic activity toward NDMA (p< 0.01, 0.05). Especially, perilla leaf, kale, soybean sprout and onion inhibited more than 80% of the NDMA induced mutagenicity in S. typhimurium TA100. Small water dropwort and perilla leaf exhibited the strong inhibitory effect (97~100%) on the growth of the AZ-521 human gastric cancer cells. Soybean sprout, water dropwort, broccoli, crown daisy, green red pepper, red pepper leaves, spinach, cabbage and sweet potato also inhibited growth of the cancer cells (p < 0.001~0.05).

A case of multiple myeloma combined with stomach cancer and related literatures were reviewed. A 67 year-old male patient entered the hospital with dysphagia and weight loss for 3 months. Peripheral blood examination revealed anemia with rouleaux formation. Total protein of the serum was 9.9g/$d{\ell}$ with hyperglobulinemia(albumin 2.7g/$d{\ell}$, globulin 7.2g/$d{\ell}$, A/G ratio 0.375). On the electrophoresis and immunoelectrophoresis of the serum, the abnormal protein with the pattern of monoclonal gammopathy(IgG-K type) was shown. There were multiple variable sized osteolytic lesions on skull X-ray and abnormal hot uptakes of ribs on bone scan and result of rib biopsy was plasmacytoma. Gastrofiberscopy was performed to search for the cause of upper gastrointestinal bleeding, revealed stomach cancer, and the result of the gastric mucosal biopsy proved to be well-differentiated adenocarcinoma.

Background: The origin site of carcinoma invading esophagogastric junction is variable. It may arise from squamous cell carcinoma of low esophagus, adenocarcinoma arising from Barrett's esophagus, adenocarcinoma of gastric cardia, or extension from proximal stomach cancer. In Korea, the majority of adenocarcinoma invading esophago-gastric junction seems to arise from proximal gastric carcinoma. Material and Method: We reviewed the data of surgically-resected gastric adenocarcinoma involving esophagogastric junction in KCCH between 1988 and 1999. Result: There were 212 cases. Male to female ratio was 156 to 56. Age distribution was between 22 and 78. Variable surgical approaches including median laparotomy, laparotomy with left or right thoracotomy, left thoracotomy, and thoracoabdominal approach were used. Postoperative pathologic stages were : Stage IA-7, IB-11, Ⅱ-25, ⅢA-73, ⅢB-34, and Ⅳ-57. Curative resection was performed in 199 patients, and total gastrectomy was performed in 200 patients. There were 77.4%(164 cases) with esophageal involvement, 74.1％(157 cases) with tumor involvement in the abdominal LN, and 8%(17 cases) with mediastinal LN metastasis. Operative mortality was 3.3%, and over-all 5 year survival rate was 35%. Conclusion: There are various surgical approaches and many things to consider for surgical resection, thoracic and abdominal approach may need for obtain proper resection margin and adequate lymph node dissection in stomach cancer invading esophagogastric junction.

The anticarcingenic effect of methanol extracts from such cruciferous vegetables as cabbage, red cabbage, Korean cabbage, kale, cauliflower, broccoli, radish root, leafy radish, rape leaves and shepherd’s purse on the growth of human K-562 leukemia cells, MG-63 osteosarcoma cells, HT-29 colon cancer cells and AGS gastric cancer cells were studied. All of cruciferous vegetables inhibited more than 70% of the growth of K-52 leukemia cells and more than50% fo rhe growth fo AGS gastric cancer cells. Particularly, kale, broccoli and shepherd’s purse showed inhibition rates of 93.5%, 93,5% and 96.3% on the growth of AGS gastric cancer cells, respectively. In case of HT-29 colon cancer cells, the methanol extracts of cabbage, kale and shepherd’purse exhibited 82.4%, 72.15, 79.4% and 95.6% of inhibitory effects, respectively. The cabbage, kale, cauliflower and shepherd’s purse extracts also highly suppressed the proliferation of MG-63 cells. Generally the 10 cruciferous vegetable we studied strongly decreased the growth of various human cancer cells in vitro, however, kale and shepherd’s showed the most effective vegetable among them.

Purpose: The aim of the study was to obtain data on the anatomic and histologic distributions, the clinical features, and the treatment results for patients with primary gastric non-Hodgkin's lymphoma. Materials and Methods: One hundred thirty-two patients who were treated at 8 university hospitals and 2 general hospitals between January 1991 and December 2000 were enrolled to evaluate clinico-pathologic features. Results: The lower one-third of the stomach was the most frequent site ($42\%$), and the most frequent chief complaint was epigastric pain ($54\%$). Gastric resection was performed in 114 cases. Pathologic findings of preoperative endoscopic biopsy specimens from the 114 patients that underwent surgery were a gastric lymphoma in 94 cases ($82\%$), a carcinoma in 15 cases ($13\%$), an ulcer in 4 cases ($4\%$), and a gastrointestinal stromal tumor in 1 case ($1\%$). The stage distributions by Musshoff's criteria were 71 cases ($54\%$) of stage IE, 36 cases ($27\%$) of stage $II_{1}E$, 8 cases ($6\%$) of stage $II_{2}E$, 2 cases ($2\%$) of stage IIIE, and 15 cases ($11\%$) of stage IVE. Histologic gradings by the Working Formulation in were 31 cases ($23\%$) of low grade, 96 cases ($73\%$) of intermediate grade, and 5 cases ($4\%$) of high grade. Chemotherapy-related complications occurred in 25 cases ($22\%$) while operation-related complications occurred in 6 cases ($5\%$). Seventeen patients ($13\%$) only underwent surgery, 19 ($14\%$) had chemotherapy (CTx) and/or radiotherapy (RTx) only, and 96 patients ($73\%$) received surgery and CTx and/or RTx. No substantial differences in survival were found in relation to the different histologic grades and different treatments. The five-year survival was $85\%$ in stage I or II and $47\%$ in stage III or IV (P=0.0000). Conclusion: Pathologic stage appears to be the single most important prognostic indicator. Survival differences according to treatment modalities were not statistically significant. However, the low number of patients treated with various approaches over a long period precludes a firm conclusion.

Gastric teratoma (GT) is an exceeding rare lesion seen most often in male infants, comprising less than $1\%$ of all teratomas in children. A 2-day-old male child was preoperatively diagnosed to have gastric teratoma on ultrasonogram and abdominal computed tomography (CT). On laparotomy, Dumbbell- shape GT was located on lesser curvature of stomach and complete excision of the tumor was performed. The histological examination revealed immature teratoma of the stomach. The child is well 10 months after surgery.

Though the occurrence of multiple primary malignant tumor is a rare finding but the reported cases of it has increased in recent years. We collected multiple primary cancer of different organ, tissue and the multicentric origin of bilaterally paired organs. This paper reports 6 cases of multiple primary malignant tumors which were experienced at Yeungnam university hospital in Taegu during the past 2 years with review of journals. The results were as follows. 1. The incidence of multiple primary cancer was 0.31% for 2 years(1987-1988). 2. The ratio between male and female was 1:1 and mean age of incidence was 54.1 years. 3. The ratio between synchronous and metachronous(interval more than 6 months) was 1:1. 4. The time interval between first and second cancer was average 2.7 years in metachronous cases. 5. The most frequent involved organ was stomach, breast and colon in order of frequency. 6. The incidence of familial cancer associations was found in one out of 6 cases. 7. The test of DNCB, multi test CMI and ratio of T4 to T8 were performed in 4 cases but there was no definitive evidence of abnormality. We concluded that every effort should be made to discover the presence of synchronous malignancies in the patients who are being treated for a known tumor, and also special care should be given to detect new metachronous lesions is required.

Purpose: This study was to observe whether the apoptotic function of tumor-infiltrating lymphocytes (TIL) is induced in human gastric epithelial dysplasia and gastric adenocarcinoma according to the role of FasL expression. Materials and Methods: A total of 56 gastric epithelial dysplasia and gastric adenocarcinoma patients were enrolled in this study: 9 cases of gastric epithelial dysplasia, 18 cases of early gastric carcinomas (EGC) and 29 cases of advanced gastric carcinomas (AGC). Immunohistochemical staining was performed for FasL and CD45, and the terminal deoxynucleotidyl transferase mediated dUTP nick end labelling (TUNEL) method was used to detect cell death in tumor-infiltrating lymphocytes. Results: 1) Positive reactions of FasL to neoplastic cells were $88.9\%$ (8/9) in gastric epithelial dysplasia, $83.3\%$ (15/18) in EGC, and $75.9\%$ (22/29) in AGC. 2) Expression of TIL was decreased in the FasL positive region and was increased in the FasL negative region, and significant expression of TIL was observed in the AGC group (P=0.001). 3) Expression of apoptotic TIL was very similar to the FasL expression, and $100\%$ expression was observed in gastric epithelial dysplasia group. 4) Expression of apoptotic TIL was increased in the FasL positive region and decreased in the FasL negative region, and significant apoptotic expression was observed in the gastric epithelial dysplasia and EGC groups (P=0.0420, P=0.0263, respectively). Conclusion: These results suggest that FasL is a prevalent mediator of immune privilege in epithelial dysplasia and cancer of the stomach.

Usually in the subtotal gastrectomy, the left and the right gastric arteries, as well as the left and the right gastroepiploic arteries are ligated. Thus, to avoid a blue stomach surgeons preserve the spleen and the short gastric arteries. When a radical subtotal gastrectomy with splenectomy is performed, meticulous caution is necessary; otherwise, the subtotal gastrectomy might have to be changed to a total gastrectomy to prevent a blue stomach. We report the case of a 67-year-old woman who had distal stomach cancer with a splenic solitary mass, for which splenic meatastasis could be excluded. We planned and performed a laparoscopy-assisted radical subtotal gastrectomy with splenectomy as the diagnostic and therapeutic option. In this case, to avoid a remnant stomach infarction or total gastrectomy we saved the left gastric artery and vein with clearing perivascular soft tissue, lymphatics, and lymph nodes. Thus the radical therapeutic goal was reached, and serious complications were avoided.
