Effects of the prolongation of survival time on immunotherapy with an extract from human tubercle bacilli (SSM) for gastric cancer in cases of non-curative resection. Statistical analysis of the results of long term observation.

e15646 Background: The oophorectomy in isolated metastasis of ovary can lead to long term survival in patients with gastric cancer, but the clinical significance of oophorectomy in stage IV gastric cancer patients is not known well in this time. Methods: We reviewed the medical record of the 55 gastric cancer patients who were metastasis or recurrent in ovary at Dongsan Medical Center, Kimyung University School of Medicine, Daegu, Korea from 1985 to 2008. Results: Twenty-one patients were metastasis to ovary at the time of diagnosis of gastric cancer, and 34 patients were recurrent in ovary after the gastric resection. The mean age was 45.3 ± 11.6 years in metastatic cancer and 46.8 ±12.6 years in recurrent cancer patients. The stage at the time of gastric resection in 34 recurrent patients were I in 3, II in 1, III in 18, and IV in 10. Adjuvant chemotherapy were performed in 26 (76.5%) patients. Oophorectomy were performed in 33 (97.1%) of recurrent cancer, and 17 (81.0%) of metastatic cancer. The 1-year and 2-year survival rate of metastatic cancer were 14.7%, and 0%, and 1-year, 2-year, and 3-year survival rate of recurrent cancer were 47.2%, 18.1%, and 0%, respectively. The median survival duration of metastatic cancer were 8.9 ±1.0 months, and recurrent cancer were 11.4 ±2.3 months. Recurrent cancer were better survival than metastatic cancer patients (p=0.014). The long-term survival (over 2 years) was noted in 5 patients of recurrent cancer patients. The stage of gastric cancer was correlated to overall survival time in total patients (p=0.028). But, the relapse-free survival time after gastrectomy is the only factor to predict survival duration after oophorectomy in recurrent cancer patients (p=0.029). Age, stage of gastric cancer, extent of involvement of ovary, and systemic chemotherapy were not related to survival time of recurrent cancer patients. Conclusions: The survival time in patients with oophorectomy in recurrent gastric cancer was correlated to relapse-free survival time after gastric resection. No significant financial relationships to disclose.

132 Background: Metastatic gastric adenocarcinoma is an incurable condition. Despite the recently reported benefits of chemotherapies, the prognosis of advanced gastric cancer remains poor. The role of surgical resection is still debatable. Therefore, we investigated the efficacy of gastrectomy plus chemotherapy for stage IV gastric cancer. Methods: We retrospectively evaluated the efficacy of gastrectomy plus chemotherapy for treating stage IV gastric cancer. Among the 753 patients with gastric cancer treated with gastrectomy at our institute between 2003 and 2010, a total of 70 patients classified into stage IV and underwent gastrectomy with perioperative chemotherapy were included in this study. In the analysis, particular attention was paid to the prognostic factors of age, gender, tissue type, metastatic site, pre or postoperative chemotherapy, single agent or combination chemotherapy and the reason for gastrectomy (palliative surgery due to stenosis, bleeding or perforation and reduction surgery). The survival rate was calculated by the Kaplan Meier method and a statistical analysis was performed using the log-rank test. Survival was calculated from the beginning of the treatment until the last follow-up or death from any cause. Results: The median age was 65 years old. Peritoneal, lymph node and liver metastasis were 28, 23, and 13 patients respectively. Fifty-three patients had diffuse type. Gastrectomy followed by chemotherapy and chemotherapy were 53 patients. Single agent chemotherapy were 42 and combination were 28 patients. Thirty-one patients were underwent palliative surgery and 39 patients were reduction surgery. One-year survival rate of all patients was 43% and the median survival time was 19.9 months. In the statistical analysis, only reduction surgery plus chemotherapy demonstrated significant survival benefit. The median survival time was significantly greater in patients undergoing reduction gastrectomy group than in those undergoing palliative gastrectomy (25.3 versus 9.8 months; p=0.005). Conclusions: Long-term survival for patients with stage IV gastric cancer who are managed with reduction surgery and chemotherapy is achievable. Further study with a larger number of patients is warranted.

E Cadherin

Purpose: To evaluate whether pretherapeutic serum soluble E-cadherin is an independent factor predicting long-term survival in gastric cancer. Gastric cancer remains the second leading cause of cancer-related deaths in the world, but a satisfactory tumor marker is currently unavailable for gastric cancer. Soluble E-cadherin has recently been found to have prognostic value in gastric cancer. Patients and Methods: One hundred sixteen patients with histologically proven gastric adenocarcinoma were included in the trial. Pretherapeutic serum was collected, and soluble E-cadherin was assayed using a commercially available enzyme-linked immunosorbent assay kit. The patients were followed up prospectively at the outpatient clinic. Results: There were 75 men and 41 women, with a mean (± SD) age of 66 ± 14 years. Forty-eight percent of tumors were located in the gastric antrum. The median survival time was 11 months. The mean pretherapeutic value of soluble E-cadherin was 9,159 ng/mL (range, 6,002 to 10,025 ng/mL), and the mean pretherapeutic level of carcinoembryonic antigen was 11 ng/mL (range, 0.3 to 4,895 ng/mL). On multivariate analysis, soluble E-cadherin is an independent factor predicting long-term survival. Ninety percent of patients with a serum level of E-cadherin greater than 10,000 ng/mL had a survival time of less than 3 years (P = .009). Conclusion: Soluble E-cadherin is a potentially valuable pretherapeutic prognostic factor in patients with gastric cancer.
