Background. The systemic immune-inflammation index (SII), based on peripheral lymphocytes, neutrophils, and platelet count, has been used as a prognostic marker for several tumors. However, use of the SII has not been reported for gastric cancer. Methods. We evaluated the prognostic value of the SII in primary and validation cohorts. We also established an effective prognostic nomogram for gastric cancer based on R language. The predictive accuracy and discriminative ability of the nomogram were determined using the concordance index (C index) and a calibration curve and were compared with TNM classifications. Results. The Kaplan-Meier survival analysis results showed that the high SII was associated with poor prognosis of gastric cancer patients in the primary and validation cohorts. SII proved to be related to tumor location, histological grade, tumor size, TNM stage, and perineural infiltration in patients with gastric cancer and was an independent prognostic factor for patients with gastric cancer. SII has a better predictive ability than other existing prognostic indexes based on inflammation, such as NLR, PLR, and MLR. The nomogram established can accurately predict the 3- and 5-year survival rates of patients with gastric cancer after operation, and its accuracy is significantly higher than that of the 8th edition of the AJCC staging system. Conclusion. SII can independently predict the overall survival of patients with gastric cancer after operation, which is superior to the existing systemic inflammatory indexes. The prognostic nomogram based on SII is a reliable model for predicting the postoperative survival of patients with gastric cancer.

181 Background: To compare the efficacy of docetaxel plus FOLFOX4 to FOLFOX4 as adjuvant chemotherapy for gastric cancer patients. Methods: 320 patients with stage IB-IV (M0) gastric cancer were enrolled into the retrospective study. All patients received a total or subtotal gastrectomy with at least D1 lymph nodes dissection. 193 patients received FOLFOX4 as adjuvant chemotherapy. 127 patients received biweekly docetaxel plus FOLFOX4 (DOF regimen) as adjuvant chemotherapy. Docetaxel was administered at 40 mg/m2 on day 1, followed by FOLFOX4 regimen. Both of the regimens were repeated every 2 weeks for a maximum of 12 cycles. Results: In comparison with patients in FOLFOX4 group, patients in DOF group were relatively younger (p=.001), with more advanced disease in pN stage (p=.035) and pTNM stage (p=.031), received more cycles of adjuvant chemotherapy (p=.004), and had a higher percentage of adjuvant radiation (p =.002). After adjustment of unbalanced variables as mentioned above, no statistical difference was observed between DOF group and FOLFOX4 group in terms of 3-year disease-free survival (54% vs 69%, p = 0.100, HR 1.362, 95% CI (0.943-1.967)) and 3-year overall survival(70% vs 72%, p = 0.810, HR 1.049, 95% CI (0.711-1.548)). Stratified analysis according to clinicopathologic characters showed that there were almost no statistical differences of 3-year overall survival rates between two groups, except the primary site (middle 1/3) (p =.025) and pTNM stage (IIb stage) (p =.035) in favor of FOLFOX4 group. The incidences of grade 3/4 adverse events were obviously higher in DOF group than in FOLFOX4 group,including decreased appetite (18.1% V 10.4%, P = 0.046), diarrhea (4.7% V 0%, p=0.004 ), hypersensitivity reactions to oxaliplatin (3.1% V 0%, p=0.024) and neutropenia (47.3% V 31.6%, p=0.004). Conclusions: Compared to FOLFOX4 regimen, adjuvant docetaxel plus FOLFOX4 did not show significant survival advantages in gastric cancer patients. However, a more serious toxicity profile was observed in docetaxel plus FOLFOX4 arm. Further studies are needed to decide whether triplet regimen is appropriate as adjuvant chemotherapy of gastric cancer.

8Th Edition

Background and Aim: Our aim was to compare the prognostic value of the American Joint Committee on Cancer (AJCC) 7th and 8th editions staging systems for patients with gastric cancer in China. Methods: A total of 1326 gastric cancer patients diagnosed between 2008 and 2012 were included. The discriminative ability of the AJCC 8th and 7th editions was compared using the Harrell’s concordance index (C-index). Results: There are two main modifications in the 8th edition. (i) pN3 staging was divided into pN3a and pN3b. The gastric cancer patients with pN3a experienced significantly better overall survival compared with those with pN3b (5-year overall survival: 34.5% vs. 15.6%, P < 0.001) (stratified by pT: pT3: 5-year overall survival: 33.9% vs. 13.2%, P < 0.001; pT4a: 32.8% vs. 16.9%, P = 0.056; pT4b: 17.0% vs. 11.1%, P = 0.048). (ii) Subgroup staging adjustments. The subgroup staging adjustments (T3N3bM0 (IIIB→IIIC), T4aN3aM0 (IIIC→IIIB), T4bN0M0 (IIIB→IIIA), and T4bN2M0 (IIIC→IIIB)) resulted in more gastric cancer patients being accurately staged. Furthermore, the C-index value of the 8th edition tumor node metastasis (TNM) staging system was significantly higher than that of the AJCC 7th TNM staging system to predict the survival of gastric cancer patients (0.701 vs. 0.685, P < 0.001). Conclusions: The 8th edition of the TNM staging system is superior to the 7th edition staging system for prediction of survival of gastric cancer patients in China.

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

The Impact

Background and Objectives: The prognosis of metastatic or unresectable gastric cancer is dismal, and the benefits of the palliative resection of primary tumors with noncurative intent remain controversial. This study aimed to evaluate the impact of palliative gastrectomy (PG) on overall survival in gastric cancer patients. Materials and Methods: One hundred forty-eight gastric cancer patients who underwent PG or a nonresection (NR) procedure between January 2011 and 2017 were retrospectively reviewed to select and analyze clinicopathological factors that affected prognosis. Results: Fifty-five patients underwent primary tumor resection with palliative intent, and 93 underwent NR procedures owing to the presence of metastatic or unresectable disease. The PG group was younger and more female dominant. In the PG group, R1 and R2 resection were performed in two patients (3.6%) and 53 patients (96.4%), respectively. The PG group had a significantly longer median overall survival than the NR group (28.4 vs. 7.7 months, p < 0.001). Multivariate analyses revealed that the overall survival was significantly better after palliative resection (hazard ratio (HR), 0.169; 95% confidence interval (CI), 0.088–0.324; p < 0.001) in patients with American Society of Anesthesiologists Physical Status (ASA) scores ≤1 (HR, 0.506; 95% CI, 0.291–0.878; p = 0.015) and those who received postoperative chemotherapy (HR, 0.487; 95% CI, 0.296–0.799; p = 0.004). Among the patients undergoing palliative resection, the presence of <15 positive lymph nodes was the only significant predictor of better overall survival (HR, 0.329; 95% CI, 0.121–0.895; p = 0.030). Conclusions: PG might lead to the prolonged survival of certain patients with incurable gastric cancer, particularly those with less-extensive lymph-node metastasis.

Background: Over the last 10 years the incidence of gastric cancer has declined significantly. Nevertheless, it remains one of the most prevalent malignancies both in Russia and worldwide. Therefore, the problems of early diagnostics, prognosis and individualized treatment choice are still on the agenda. Much attention is paid to the evaluation of molecular biological characteristics of the tumor, as well as to the development of multiparametric prognostic systems for gastric cancer based on its identified characteristics. An important place among potential tumor biological markers belongs to matrix metalloproteinases (MMPs) involved into all the stages of tumor progression, first of all, into the regulation of invasion and metastasizing.Aim: Comparative quantitative evaluation of some MMP family members (MMP-2, 7, and 9) and one of the tissue MMP inhibitors (TIMP-2) levels in the tumors and adjacent histologically unchanged mucosa in gastric cancer patients, the analysis of their associations with the main clinical and pathological features of the disease and its prognosis.Materials and methods: Sixty six (66) primary gastric cancer patients (32 male and 34 female) aged 24 to 82 years (median, 61 year) were recruited into the study. Twenty two (22) patients were with stage I of the disease, 11 with stage II, 28 with stage III, and 5 with stage IV. The concentrations of the proteins studied were measured in the tumor and unchanged mucosa extracts by standard direct ELISA kits (Quantikine®, R&D Systems, USA).Results: Tumor MMP-2, 7 and 9 levels were significantly increased, compared to those in the adjacent histologically unchanged mucosa, in 80, 70 and 72% of gastric cancer patients, respectively, while the increase of TIMP-2 level found in 61% of the tumors was not statistically significant. Tumor MMP-2 and TIMP-2 content was increasing significantly with higher T index – size and advancement of the primary tumor (p < 0.01 and p < 0.05 respectively). Tumor MMP-2 level was also increasing in parallel with the N index (regional lymph node involvement; p < 0.01); it was significantly higher in the patients with distant metastases than in those without them (p < 0.05). Tumor MMP-9 and MMP-7 concentrations were not significantly associated with the indices of the tumor progression. The patients were followed up for 1 to 85 months (median, 18.3 months). According to the univariate analysis, high (> 32.6 ng/mg protein) MMP-2 and low MMP-7 (< 1.1 ng/mg protein) levels in the gastric cancer tissue represent statistically significant unfavorable prognostic factors for overall survival. Increased TIMP-2 level is associated with a non-significant decrease in the overall survival (p > 0.05), whereas the MMP-9 level was unrelated to the gastric cancer prognosis. Only T index (p = 0.0034) and tumor MMP-7 content (p = 0.026) remained independent prognostic factors in the multivariate regression analysis.Conclusion: The majority of gastric cancer patients demonstrate a significant increase in the expression of three MMP family members, i.e. gelatinases (MMP-2 and 9), and matrilysin (MMP-7), in the tumors, as compared to adjacent histologically unchanged mucosa. Only MMP-2 levels were associated with the disease progression, increasing with higher TNM system indices. High MMP-2 and low MMP-7 content in the gastric cancer tissue are significant unfavorable prognostic factors for the overall survival in the univariate analysis, but only MMP-7 has retained its independent prognostic value in the multivariate assessment.

AbstractAimThis study aimed to evaluate and compare the efficacy and toxicity of common regimens used as perioperative chemotherapy including ECF, DCF, FOLFOX, and FLOT to identify the most effective chemotherapy regimen with less toxicity.Material and MethodsThis retrospective cohort study was based on 152 eligible gastric cancer patients recruited in a tertiary oncology hospital in Isfahan, Iran (2014-2019). All resectable gastric cancer patients who had received one of the four chemotherapy regimens including ECF, DCF, FOLFOX, or FLOT, and followed for at least one year (up to five years) were included. The primary endpoint of this study was Overall Survival (OS), Progression-Free Survival (PFS), Overall Response Rate (ORR), and R0 resection. We also considered toxicity according to CTCAE (v.4.0) criteria as a secondary endpoint. Cox -regression models were used applied to estimate OS and PFS time, controlled for relevant covariates.ResultsOf included patients, 32(21%), 51(33.7%), 37(24.3%), and 32(21%) had received ECF, DCF, FOLFOX and FLOT, respectively. After the median 25 months follow-up, overall survival was higher with the FLOT regimen in comparison with other regimens (hazard ratio [HR] = 0. 052). The median OS of the FLOT regimen was not reachable in Kaplan-Meier analysis and the median OS was 28, 26, and 23 months for DCF, FOLOFX, and ECF regimens, respectively. On the other hand, a median PFS of 25, 17, 15, and 14 months was observed for FLOT, DCF, FOLFOX, and ECF regimens, respectively (Log-rank = 0. 021). FLOT regimen showed 84. 4% ORR which was notably higher than other groups (p-value<0. 01).ConclusionsFor resectable gastric cancer patients, the perioperative FLOT regimen seemed to lead to a significant improvement in patients’ OS and PFS in comparison with ECF, DCF, and FOLFOX regimens. As such, the FLOT regimen could be considered as the optimal option for managing resectable gastric cancer patients.

Abstract Backgroud Obg-like ATPase 1 (OLA1) is a member of the Obg family of P-loop NTPases and has recently been detected in several human cancer cells. However, its expression type and clinical relevance in gastric cancer remains unclear. Methods In the present study, 2 datasets downloaded from the open Gene Expression Omnibus database were used to evaluate the mRNA level of OLA1 in gastric cancer. Quantitative Reverse Transcription PCR further validated the mRNA expression in gastric cancer tissues. Immunohistochemistry was performed on gastric cancer tissue microarray to assess OLA1 protein expression type, prognostic value, biological significance and its association with Snail in 334 patients of gastric cancer. The prognostic value of combination of OLA1 and Snail has been evaluated. Results The results showed that OLA1 mRNA and protein were elevated in gastric cancer tissues. High expression of OLA1 was significantly associated with aggressive features, such as tumor size, lymph node metastasis and TNM stage (P = 0.0146, P = 0.0037, P < 0.001, respectively). Moreover, high levels of OLA1 predicted worse overall survival. Multivariate Cox regression analysis indicated that high expression of OLA1 was an independent prognostic factor for poor overall survival (hazard ratio, 0.573; 95% confidence interval, 0.376–0.872; P = 0.009). Additionally, OLA1 expression was positively correlated with Snail, and combination of them revealed improved prognostic accuracy for gastric cancer patients. Conclusions Our results suggested that OLA1 high expression was considered as an independent factor for the prediction of unfavorable prognosis in gastric cancer patients, and we believe that OLA1 could serve as a biomarker of poor prognosis and a novel target in treating gastric cancers.
