Abstract PDF: Purpose：Although several chemotherapy regimens used against advanced and recurred gastric cancer have been studied extensively in an attempt to further improve the prognosis of patients, no standard chemotherapeutic regimens have been established. The aim of this study was to determine the anti-tumor efficacy and safety of TS-1 or TS-1 plus cisplatin (CDDP). Materials and Methods：From December 2004 to June 2007, we treated 43 patients with unresectable or recurred gastric cancer either with 80 mg/m2 of TS-1 for 28 days, which was followed by a 2-week rest, or with 80 mg/m² of TS-1 for 28 days and 60 mg/m² of CDDP on day 3 every 6 weeks.
Results
：Tumor response rates in the primary chemotherapy group and in the recurrent group were 46.7% and 21.4%, respectively. The median survival rates in the primary and the recurrent group were 14 months and 8 months, and it was not significantly different. But the one-year survival rates according to the kinds of regimens (TS-1 or TS-1/CDDP group) were significantly different (P=0.0014). The incidences of grade 3 or 4 adverse effects were 18%, respectively.
Conclusion
：The anti-tumor efficacy and safety of TS-1 and TS-1 plus CDDP in unresectable or recurred gastric cancer patients seemed to be high with modest adverse effects, thus suggesting the possible use of this regimen for unresectable or recurred gastric cancer patients.

Abstract PDF: Purpose：To investigate the efficacy and safety of docetaxel based chemotherapy as a secondline treatment in patients with metastatic or recurrent gastric cancer. Materials and Methods：Between January 2001 and March 2007, 28 patients with recurrent or metastatic gastric cancer were enrolled. The administered doses of decetaxel was 75 mg/m² on day 1 and 5, cisplatin 60 mg/m² on day 3, 5-FU 600 mg/m² over 24 hrs on day 1 to day 5, every 4 weeks. The response was assessed every 2 cycles. The toxicities were evaluated for every course of chemotherapy according to National Cancer Institute-common toxicity criteria (NCI-CTC).
Results
：For response rates, 3 (10.7%) partial response, 13 (46.4%) stable disease, and 12 (42.9%) progressive disease, respectively. The overall disease control rate was 57.1%. The median time to progression was 3.0 months (2-8 months). Median overall survival was 8 months (5-11 months). NCI-CTC grade 3 leukocytopenia occurred in 1 cases, grade 3 anemia in 1case and grade 3 nausea/vomiting in 2 cases.
Conclusion
：Docetaxel based chemotherapy has a tolerable efficacy with acceptable toxicities in patients with recurrent gastric cancer as a second-line treatment.

Abstract PDF

Purpose：A difference of a pathologic characteristic in proportion to depth of invasion analyzed in T2 gastric cancer and a difference of depth of invasion examined an influence to lymph node metastasis and prognosis. Materials and Methods：The clinicopathologic outcomes of 432 patients who underwent curative resection for pT2 stage gastric cancers from 1995 to 1999 were reviewed retrospectively. We are compared on lymphatic metastasis, stage distribution, histologic classification, Bormann’s classification, Lauren classification, vessel invasion, lymphatic invasion, neural invasion and 5-year survival rate of pT2 groups(mp vs. ss).
Results
：pT2b(ss) group compare to pT2a(mp) in Lauren classification, ratio of diffused type was higher(p<0.05) and in Bormann classification, infiltration type was higher (p<0.01). Vessel and lymphatic invasion, neural invasion showed significant difference between pT2a(mp) and pT2b(ss) (p<0.01). Difference noted between pT2a(mp) and pT2b(ss) group in a lymph node metastatic rate, degree of a metastasis and stage distribution (p<0.01). On stratifying patients according to depth of invasion, 5-year suvival rate for those with pT2a(mp) group was significantly greater than those with pT2b(ss) group(82.4% vs. 47.4%, respectively: P<0.01). In this study, appeared with the significant prognostic factor in 5-year suvival rate which multivariate analysis, depth of invasion(P<0.05) and lymph node metastasis (P<0.01) that enforced the total gastric cancer patient who had T2 gastric cancer with the object noted, but for patients with accurately staged pN0 group, suvival characteristics were similar for pT2a (mp) and pT2b(ss) gastric cancer (P=0.97).
Conclusion
：The subclassification of pT2 gastric cancer into pT2a(mp) and pT2b(ss) is necessary to demonstrate their different prognosis.

Abstract PDF: PURPOSE: Various postoperative adjuvant chemotherapy regimens have been proposed for the patients with advanced gastric cancer. The majority of clinical trials have shown no significant difference in the survival benefit. The aim of this study was to compare the survival rates of postoperative adjuvant chemotherapies used in stage III gastric cancer patients who received curative gastrectomy. MATERIALS AND METHODS: Between 1990 and 1999, a survival analysis was performed in 260 patients who received curative gastric resection and postoperative adjuvant chemotherapy. The patients were divided into four groups according to the chemotherapeutic regimens received. The groups were: the F group: furtulon alone, FM group: furtulon and mitomycin, FAM group: 5-FU, adriamycin and mitomycin, FLEP group: 5-FU, leucovorin, etoposide and cisplatin. The survival rates were analyzed using the Kaplan-Meier method and the Cox proportional hazards model. RESULTS: There were no differences among the groups of patients with regard to tumor characteristics except for lymph node metastasis and the ratio of metastasis to lymph nodes. In the FLEP group, the ratio of metastasis to lymph nodes was higher than in the other groups. The five and ten year survival rates of F, FM, FAM and FLEP were 51.9%, 28.9%, 59.5%, 49.8%, 66.1%, 57.4% and 30.0%, 27.5%, respectively. The univariate analysis showed that age, Borrmann type, lymph node metastasis, ratio of metastasis to lymph nodes, postoperative adjuvant chemotherapy and recurrence were significant factors for survival. For the multivariate analysis, recurrence, age, Borrmann type, ratio of lymph node metastasis and lymph node dissection were independent prognostic factors; however, the postoperative adjuvant chemotherapy was not an independent prognostic factor. CONCLUSION: The FAM regimen was the most beneficial postoperative adjuvant chemotherapy for improved survival rates; the FM regimen was the second and the FLEP regimen was the last. In order to determine the effectiveness of postoperative adjuvant chemotherapy in stage III gastric cancer, well designed prospective studies including a surgery only group will be needed.

Abstract PDF: Small bowel tumors have been difficult to diagnose because of low incidence and absence of specific symptoms. There are no efficient and accurate tests available for diagnosis. Capsule endoscopy is an efficient diagnostic tool for small bowel disease and obscure gastrointestinal bleeding. We diagnosed two cases of small bowel gastrointestinal stromal tumor (GIST) diagnosed by capsule endoscopy that were treated by surgery. A 68 year old male presented with abdominal pain. The capsule endoscopy showed fungating ulcer mass at the jejunum. A 55 year female presented with melena. The capsule endoscopy showed an intraluminal protruding mass with a superficial ulcer at the jejunum. Two cases were diagnosed with GIST after surgery. We report these two case diagnosed by capsule endoscopy and review the medical literature.

Abstract PDF: The aim of present study was to elucidate whether the expression of nm23 protein might be of clinical value as prognostic factor in gastric cancer. The expression of nm23 protein was analyzed using immunohistochemical method in formalin-fixed and paraffin-embedded tissue samples of 76 gastric carcinoma patients. The cytoplasmic immunoreactivity of nm23 protein were detected in 53.9%(41/76). When the immunoreactivity of nm23 protein with TNM status and other histopathologic findings were compared by using Chi-Square test, nm23 was found to have correlations with the lymph node metastasis(p=0.04), the number of metastatic lymph node, and the invasion of lymphatic vessels(p=0.007). But, it has no correlation with TNM status. The conventional prognostic factors such as the depth of invasion, lymph node metastasis, distant metastasis, Borrmann type, size of tumor, and the curability of operation was found to have strong correlation with the survival time(p<0.003). But, the expression of nm23 protein was not significantly correlated with that in survival analysis. These results showed that the expression of nm23 protein is not a useful prognostic indicator in gastric cancer.

Abstract PDF: Insulinoma is the most frequent endocrine tumor of the pancreas and the first of the endocrine-secreting tumor of the gut to be recognized by Nicholls in 1902. Recurrent episodes of hypoglycemia is the main cause of the symptoms and signs which were sweating, pallor, dizziness, habitual change, convulsion and coma. In 1935, Whipple and Frants were described so-called “Whipple's triad”: the patient's symptoms occur with fasting or exercise; at the time of symptoms, the serum glucose in 50mg/dl or less; and the symptoms are relieved by the administration of glucose. While these criteria were timely, they proved to be rather nonspecific and may be found in other conditions that result in fasting hypoglycemia. We experienced a 44-year-old female patient who had repeated attacks of convulsion, unconsciousness and coma for 3 years. Although she has been treated with anticonvulsant, the symptoms and signs were not disappeared. At the time of administration, she was a full coma state due to hypoglycemia and was dramatically reversed by intravenous administration of the glucose solution. The preoperative test such as provocative test, abdominal CT and celiac angiography revealed insulinoma and after enucleation the pathologic diagnosis was the same. We like to report an adult female patient with insulinoma and the review of literatures briefly.

Abstract PDF: Splenic abscess is an uncommon lesion and may be present either as a localized area of infection in the spleen or as a part of generalized sepsis. The diagnosis is difficult because of the rather nonspecific clinical picture. Hence, splenic abscess has a high mortality rate and is after diagnosed only at autopsy. Computerized tomography (CT) offers the clinician a reliable tool for the diagnosis of intra-abdominal abscess. A successful outcome is dependent on an early diagnosis and prompt treatment by splenectomy with antibiotic cover. We experienced a care of splenic abscess which was diagnosed by CT and treated by splenectomy with antibiotics. Postoperative course was relatively uneventful.

Abstract PDF: Leriche syndrome is a chronic disorder mostly in male and is a specific symptom complex due to thrombotic obliteration of the aortic bifurcation as result of an atherosclerotic change. The symptoms include 1) extreme liability to fatigue of both lower limbs; 2) symmetric atrophy of both lower limbs; 3) pallor of the legs and feets; 4) inability to maintain stable erection. There are several methods for surgical management of this disorder; 1) thromboendarterectomy with or without sympathectomy; 2) aortoiliac bypass graft; 3) aortofemoral bypass graft. Here we report a case of Leriche syndrome which was successfully managed with aortobifemoral bypass graft with Dacron and reviewed literatures on it briefly.
