39 Background: In patients with stage 1 gastric cancer, surgical resection without neoadjuvant therapy is offered as the first line treatment. However, some of these patients are found to have higher stage after resection and miss the opportunity for neoadjuvant therapy. Preoperative patient and tumor characteristics may be predictive of the likelihood of pathological upstaging in stage 1 gastric cancer patients who have not received neo-adjuvant therapy. Methods: The National Cancer Database was queried for patients diagnosed from 2004-2015 with clinical stage 1 gastric adenocarcinoma who had undergone surgical resection without neoadjuvant therapy. Univariate analysis and multivariable logistic regression were conducted to determine pre-operative factors associated with pathological upstaging. Candidate variables examined included age, sex, race, tumor size, histology, grade, tumor location, days to surgery, and lymphovascular invasion. Results: Analysis was conducted on 8,015 clinical stage 1 patients. Overall 1,981 (25%) patients were upstaged. On multivariable logistic regression analysis, significant predictors of upstaging included increasing tumor size [ref : size < 1 cm, 1-2 cm aOR=3.8 (95% CI 2.3-6.1); 2-4 cm aOR=12.4 (7.9-19.5); > = 4cm aOR=25.9 (22.9-56.4)], younger age [ref: > = 75, < 50 aOR=1.7 (1.4-2.1), 50-65 aOR=1.4 (1.2-1.6), 65-75 aOR=1.2 (1.1-1.5)], male gender [aOR=1.16 (1.0-1.3)], presence of diffuse type gastric cancer [aOR=2.3 (1.7-3.2)], mucinous type [aOR=1.7 (1.1-2.5)], or signet ring cell histology [aOR=1.6 (1.3-2.0)] compared to intestinal histology, presence of lymphovascular invasion [aOR=6.0 (5.0-7.1)], and increasing grade [ref: grade 1, grade 2 aOR=2.30 (1.7-3.5); grade 3 aOR=4.9 (3.6- 6.7)]. Conclusions: A quarter of all patients thought to have stage 1 gastric cancer prior to surgery had higher pathologic stage at time of resection. Patients with the above risk factors may be understaged with currently available diagnostic tools. The addition of neoadjuvant therapy should be considered when the above risk factors are present in clinical stage 1 patients.

Aim.To investigate whether tumor size is a reasonable indication for adjuvant chemotherapy for T3-4aN0M0 gastric cancer patients after D2 gastrectomy.Method. We performed a retrospective study of 269 patients with a histological diagnosis of T3-4aN0M0 stage gastric cancer who underwent D2 radical surgery at the Sun Yat-sen University Cancer Center or the Sixth Affiliated Hospital of Sun Yat-sen University between January 2006 and December 2010. The follow-up lasted until June of 2015. Chi-square tests and Kaplan-Meier methods were employed to compare the clinicopathological variables and prognoses.Result. For this group of patients, univariate analyses revealed that tumor size (p<0.001), pathological T stage (p<0.001), and tumor location (p=0.025) were significant prognostic factors. Adjuvant chemotherapy did not exhibit prognostic benefits. For patients with tumors larger than 5 cm, univariate analysis revealed that tumor location (p=0.007), Borrmann type (p=0.039), postoperative chemotherapy (p=0.003), and pathological T stage (p<0.001) were significant prognostic factors. Multivariate analysis revealed that postoperative chemotherapy and pathological T stage were independent prognostic factors.Conclusion. Our results imply that tumor size should be a critical factor in the decision to utilize adjuvant chemotherapy for T3-4aN0M0 gastric cancer patients after D2 gastrectomy. Additional randomized controlled trials are required before this conclusion can be considered definitive.

Aim: Caveolin-1 plays a significant role in the pathogenesis of various carcinomas and its expression affects the survival of cancer patients. However, the molecular function of caveolin-1 and its possible clinical importance has remained uncertain in gastric cancer. No clinical trial has examined serum caveolin-1 levels in gastric cancer patients so far, instead all available results were provided from studies conducted on tissue samples. In the current study, we analyzed the soluble serum caveolin-1 levels in gastric cancer patients, and specified its associations with the clinical factors and prognosis. Material and Methods: Sixty-three patients with pathologically confirmed gastric cancer were enrolled into the trial. Serum caveolin-1 concentrations were detected by ELISA method. Thirty healthy subjects were also included in the study. Results: The median age of patients was 62 years, ranging from 28 to 82 years. The serum caveolin-1 levels in gastric cancer patients were significantly higher than those in control group (p < 0.001). The common clinical parameters including patient age, sex, lesion localization, histopathology, histological grade, disease stage, and various serum tumor markers (e.g. LDH, CEA, and CA 19.9) were not found to be associated with serum caveolin-1 levels (p > 0.05). Similarly, no correlation existed between serum caveolin-1 concentration and chemotherapy responsiveness (p = 0.93). Furthermore, serum caveolin-1 level was not found to have a prognostic role (p = 0.16). Conclusion: Even though it is neither predictive nor prognostic, serum caveolin-1 level may be a valuable diagnostic indicator in patients with gastric cancer. Key
