Despite improvements in the surgical treatment of gastric adenocarcinomas, the recurrence rates remain high in patients with advanced-stage disease. Most of the recurrence occurs within 3 years of the surgical resection, and nearly $90\%$ of the patients with recurrence die within 2 years of the diagnosis of recurrence. A recent study analyzed recurrence patterns for patients who had undergone a potentially curative gastrectomy. For those patients, $33\%$ of the recurrences involved locoregional sites, $44\%$ the peritoneum, and $38\%$ distant sites. A 51-year-old female patient was diagnosed with stomach cancer and underwent a total gastrectomy with D2 lymph node dissection during Oct. 1999. The pathologic report indicated a T3N1M0 tumor. We performed immunochemotherapy for 2 years with regular follow up. A gastrofiberscopic examination done during sep. 2004, cancer recurrence was found at the Kim's tie site of the jejunual loop. We did an abdominal exploration and a segmental resection of cancer site with pathologically negative resection margins. After the operation, we started secondary chemotherapy with TS-1.

A 38-year-old man presented with abdominal discomfort and was diagnosed as type 3 advanced gastric cancer with multiple liver and lung metastases (Stage IV). Endoscopic forcep biopsy revealed moderately differentiated adenocarcinoma, which stained positive HER2 (Human epidermal growth factor receptor) on immunohistochemistry. We started chemotherapy with FP (5-Fluorouracil plus Cisplatin) plus trastuzumab. After 6 cycles of FP plus trastuzumab chemotherapy, there were partial response in the liver, lung and lymph nodes metastasis. Especially, metastatic lung lesions showed remarkable improvement. Chemotherapy with FP plus trastuzamab was effective for HER2 positive advanced cancer with multiple liver and lung metastases. Through active research on target therapy about advanced gastric cancer, we expect to improve the survival rate and quality of life of patients with advanced gastric cancer who can not undergo curative resection.

Purpose: The aim of this study was to examine the usefulness of positron emission tomography (PET)-computed tomography (CT) in the pre-operative staging of gastric cancer. Materials and Methods: Between February 2006 and August 2008, PET-CT and CT were performed on 70 patients diagnosed with gastric cancer by gastrofiberscopic biopsy. The sensitivities, specificities, Positive predictive value (PPV), and negative predictive value (NPV) of PET-CT and CT imaging for the detection of gastric cancer TNM staging were compared. Results: The detection rates for the primary tumor were as follows: PET-CT, 81.4% (57/70); and CT, 42.9% (30/70). For both early gastric cancer (EGC) and advanced gastric cancer (AGC), PET-CT was more accurate than CT in detecting the lesions. As the size of the tumor exceeded 3 cm, the detection rate increased. The sensitivities, specificities, PPV, and NPV of PET-CT for lymph node staging were 55.6%, 81%, 86.2%, and 45.9%, while the sensitivities, specificities, PPV, and NPV of CT were 40.0%, 85.7%, 85.7% and 40%, respectively. One case of multiple liver metastasis and two cases of dual primary cancer (rectal and pancreatic cancers) were detected by PET-CT. PET-CT also had a higher detection rate for all histologic types of primary tumors. PET-CT was more accurate than CT in detecting primary gastric cancer lesions. The detection of nodal metastasis by PET-CT was similar to CT; small-sized tumors or EGC detection rates were not high. However, PET-CT provided additional information to detect distant metastases and dual primary cancers and reduced unnecessary laparotomies to detect peritoneal seeding or carcinomatosis. Conclusion: It would be useful to make a pre-operative diagnosis of gastric cancer and determine treatment if PET-CT were added to other routine pre-operative studies.

Backgrounds : Gastric cancer is one of the most frequent causes of cancer-related deaths worldwide. Gastric cancer patients frequently exhibit distant metastasis at the time of diagnosis and at present, there is no standard regimen after operation or chemotherapy to prevent metastasis and recurrences. Aims : The objective of the study was to compare the overall survival and disease free survival in patients treated with wheel balance therapy (WBT) with patients treated with WBT alone or the combination of WBT and conventional therapy and see if there were any significant improvements in survival between the two groups. Setting & Design : East-West Cancer Center at Daejeon University: retrospective study. Materials & Methods : We retrospectively analyzed 62 patients with stage III (40 patients) and stage IV (22 patients) gastric cancer who have received operation or chemotherapy 2 months prior to beginning WBT. The patients followed the WBT protocol which includes herbal medicine such as PSM capsules, OnePlus syrup, or HAD capsules which prevent metastasis and recurrences. Overall survival and disease free survival were analyzed and the patients were treated for 89.55 weeks and 49.27 weeks (median value) for stages III and IV, respectively. Statistical analysis used : Overall survival and disease free survival were estimated using the Kaplan-Meier method and the WBT and combination treatment arms were compared using the log rank test. Results : For stage III, the 3 year overall survival was 78.5% and disease free survival was 78.3%. Metastasis and recurrence occurred in 13 of 40 patients (32.5%). For stage IV, the 2 year overall survival was 18.2% and disease free survival was also 18.2%. Metastasis and recurrence occurred in 19 of 22 patients (86.4%). No significant difference was found statistically between the WBT alone and combination treatment arms though the combination regimen showed superiority (overall survival p=0.5093, disease free survival p=0.5175). Conclusions : WBT yielded satisfactory results in prolonging survival and preventing metastasis and recurrence in gastric cancer patients. The major treatment unit of WBT is composed of herbal medications (HAD, PSM capsules, OnePlus syrup) and a randomized, prospective study should be carried out using only this treatment unit in the future.

Purpose: The prognosis for patients with a Borrmann type IV gastric cancer is extremely poor despite an aggressive surgical approach. We evaluated the clinicopathological features for Borrmann type IV cancers to find treatment strategy. Materials and Methods: The 1098 patients with advanced gastric cancer who underwent surgical resection between 1990 and 2001 were analyzed. These patients were divided into two groups: 81 patients with a Borrmann type IV carcinoma, and 1017 patients with all other types of gastric carcinomas. Results: Patients with a Borrmann type IV carcinoma were younger than those with other types, and female was prevalent (p=0.000). Of the patients with a Borrmann type IV gastric carcinoma, 68 patients (84%) were classified as stage III or IV at the initial diagnosis. The histologic type was commonly undifferentiated and serosal infiltration; nodal involvement and lymphatic invasion were more frequent in patients with a Borrmann type IV than in those with other types of cancer. Multivariate analysis confirmed that the extent of lymph node metastasis was a negative prognostic factor for Borrmann type IV gastric carcinomas. The curability for a Borrmann type IV carcinoma was only 53.1%, and peritoneal dissemination rate was 25.9%. The predominant pattern of recurrence for a Borrmann type IV gastric carcinoma was peritoneal dissemination, and it was significantly different with other types (93.1% vs 55.8%, P<0.05). The 5-year survival rate of patients with a Borrmann type IV gastric carcinoma was significantly lower than those of patients with other types of cancer, even though a curative resection had been accomplished (26% vs 63%, p<0.005). The 5-year survival rates of patients with a Borrmann type IV carcinoma following a curative resection were 44.9%, 24%, and 0% for stages II, III and IV, respectively (p<0.05). Conclusion: Because the prognosis for patients of a Borrmann type IV gastric cancer is extremely poor despite a curative resection, preoperative and/or intraperitoneal chemotherapy should be considered. And diagnostic laparoscopy and peritoneal cytology may be used to play an important role in accurate staging workup. (J Korean Gastric Cancer Assoc 2006;6:97-102)
Purpose: RUNX3, a novel tumor suppressor, is frequently inactivated in gastric cancer. In the present study, we examined the pattern of RUNX3 expression in gastric cancer cells from gastric cancer specimens and the impact of its alteration on clinical outcome. Materials and Methods: A total of 124 samples of both gastric cancer and normal tissue were obtained from 124 patients who underwent curative gastrectomy at the Seoul Medical Center from January 2001 to December 2005. RUNX3 expression was determined by immunohistochemical staining, and the results were analyzed. Statistical analysis wabased on clinicopathological findings and differences in survival rates. Results: The mean age of the patients was 61 years, and the male:female ratio was 1.9:1. The expression rate of RUNX3 was 59.7% (74/124). The expression rate was higher in differentiated gastric cancers (nucleus: 9.1%, cytoplasm: 57.6%) than in the undifferentiated types (nucleus: 5.2%, cytoplasm: 46.6%) (P=0.133). The 5-year survival rates according to RUNX3 expression determined from cancer tissue were 88.9% for the nucleus $\pm$ cytoplasm(+) group of patients, 76.1% for the cytoplasm only (+) group of patients, and 65.3% for the RUNX3 negative expression group of patients (P=0.626). Only UICC TNM staging showed statistical significance related to the survival rate, as determined by multivariate analysis. Conclusion: The RUNX3 expression rate was higher in differentiated gastric cancer than in the undifferentiated types without significance. Although RUNX3 expression predicted better survival, based on multivariate analysis, the finding was not statistically significant. More cases should be further evaluated.

Purpose: The aim of this study was to evaluate the significance of palliative gastrojejunostomy for treating patients with unresectable stage IV gastric cancer, and as compared with laparotomy for treating patients with incurable gastric cancer. Materials and Methods: We retrospectively studied 167 patients who could not undergo resection without obstruction at Korea University Hospital from 1984 to 2007. They were classified into two groups, one that underwent palliative gastrojejnostomy (the bypass group, n=62) and one that underwent explo-laparotomy (the O&C group, n=105), and the clinical data and operative outcomes were compared according to the groups. Results: For the clinical characteristics, there were no differences of age, gender and liver metastasis between the bypass group and the explo-laparotomy group, but there was a significant different for the presence of peritoneal metastasis (P=0.001). There was no difference between two groups for the postoperative mortality and morbidity. For the postoperative outcomes, the duration of the hospital stay (29.25 vs 16.67) and the frequency of re-admission were not different, but the median overall survival (4.3 months vs. 3.4 months, respectively) was significantly different. By multivariate analysis, the presence of peritoneal metastasis was identified as the independent prognostic factor for incurable gastric cancer. Conclusion: A prophylactic bypass procedure is not effective for improving the quality of life and prolonging the life expectancy of unresectable stage IV gastric cancer patients without obstruction.
In gastric cancer, the only potentially curative treatment is surgery that attempts to achieve curative (R0) resection. However, despite the use of curative resection, a recurrence develops in a high percentage of patients, especially in cases of serosa and/or lymph node involvement. As a strategy to improve the survival of the patients with resectable advanced gastric cancer, neoadjuvant chemotherapy has been evaluated in several phase II trials and a few phase III trials. The results of these trials have confirmed the feasibility and safety of this approach with no apparent increase in surgical complications. Recently, the findings of a large phase III randomized trial (MAGIC trial) have indicated that compared to the use of surgery alone, perioperative chemotherapy, using both a neoadjuvant and adjuvant strategy, decreased the number of T and N stage cancers and improved survival. The results of another recent phase III trial (FNLCC 94012/FFCD 9703) also showed that compared to the use of surgery alone, perioperative chemotherapy improved the R0 resection rate and survival. In both trials, the improved outcomes may be attributed to the use of neoadjuvant chemotherapy because of poor compliance with adjuvant chemotherapy. These results cannot be directly translated to clinical practice in Korea due to differences in surgical techniques and outcomes. However, the findings of a few small phase II and III trials performed in patients with locally advanced gastric cancer in Korea have also suggested that neoadjuvant chemotherapy would result in the improvement of the R0 resection rate and down-staging of the disease. More effective chemotherapy regimens are needed in future large randomized trials to determine the subset of patients that will benefit from neoadjuvant chemotherapy and to determine the extent of benefit.

Purpose: KLF6, a member of the KLF family, is a ubiquitous zinc finger tumor suppressor protein that is mutated in several human cancers. Our aim was to determine whether the expression pattern of KLF6 might be associated with gastric cancer development and, if so, to determine to which pathologic parameter it is linked. Materials and Methods: For the construction of the gastric cancer tissue microarray, 85 paraffin-embedded tissues containing gastric cancer areas were cored 3 times and transferred to the recipient master block. The expression pattern of KLF6 was examined on tissue microarray slides by using immunohistochemistry and was compared with pathologic parameters, including histologic type, depth of invasion, lymph node metastasis, and peritoneal dissemination. Results: The KLF6 protein was expressed on superficial and foveolar epithelial cells in the gastric mucosa. We found loss of KLF6 expression in 28 ($32.9\%$) of the 85 gastric cancer tissues. There was a significant correlation between loss of KLF6 expression and lymph-node metastasis. However, other pathologic parameters, such as histologic type, depth of invasion, and peritoneal dissemination, were not statistically associated with loss of KLF6 expression. Conclusion: Our findings suggest that loss of KLF6 expression may contribute to abnormal regulation of gastrointestinal epithelial cell growth and differentiation and to the development and/or progression of Korean gastric cancer.
Gastric cancer is the second most common cancer and the third leading cause of cancer-related deaths in Korea. Many cases of gastric cancer are detected in the early stages on standard medical examinations; complete surgical and endoscopic resection is the most recommended treatment for early-stage gastric cancer. Nevertheless, many patients have already progressed to advanced gastric cancer (AGC) upon diagnosis, and the prognosis of such patients is very poor. Combination chemotherapy has been shown to produce a better quality of life (QOL) and to increase overall survival in AGC patients. However, approximately 50% of patients do not respond to the current first-line chemotherapy, while most patients who do respond eventually show disease progression. Accordingly, various second-line regimens have been investigated, and active salvage chemotherapy has been shown to improve the QOL and clinical outcomes in select AGS patients who can tolerate it. There is also an increasing need for neoadjuvant therapy for treating gastric cancer; therefore, various clinical trials have been set up to investigate different regimens. Neoadjuvant therapy is currently established as the standard treatment for locally AGC in Europe; it has contributed to lowering the nodal stages and has reduced overall mortality rates. Despite these benefits, many uncertainties remain. Therefore, further prospective, high quality randomized controlled trials for neoadjuvant therapies are needed to clarify their clinical benefits and to establish the most effective treatment strategies for AGC.
