RESUMEN
Objective:To establish a nomogram to predict overall survival of patients with stage Ⅰ-Ⅲ gastric cancer (GC) based on preoperative inflammatory markers.Methods:Clinicopathological and follow-up data of 1 035 patients with stage Ⅰ-Ⅲ gastric cancer operated at He'nan Cancer Hospital between May 2015 and Oct 2016 were retrospectively collected. A nomogram was established based on prognostic factors. Harrell's concordance index (C-index), receiver operating characteristic (ROC) curve, calibration curve and decision curve analysis (DCA) were used to verify the performance of the model according to differentiation, calibration and clinical utility.Results:A total of 1 035 patients were enrolled . The median follow-up time was 41.9 months; According to the optimal cutoff value, 170 were with elevated neutrophil-to-lymphocyte ratio (NLR) and 865 with a reduced ratio; 562 in elevated platelet-to-lymphocyte ratio (PLR) vs. 473 in the reduced group; fibrinogen/albumin ratio (FAR) elevated in 108 group vs. 972 in the reduced group; 180 in the prognostic nutritional index score (PNI) elevated group and 855 in the reduced group. Two hundred and sixty-seven patients were categorized at stage Ⅰ, 334 at stage Ⅱ ,434 at stage Ⅲ. Multivariate regression analysis showed tumor location, vascular tumor thrombus, pTNM stage, FAR, PNI and NLR were independent prognostic factors (all P<0.05). The C-index of the nomogram was 0.723 (95% CI: 0.710 -0.736) and had better clinical utility than the American Joint Committee on Cancer (AJCC) 8th TNM staging system 0.693 (95% CI, 0.681 -0.705). The calibration curve of the nomogram showed that the predicted survival rate was consistent with the actual survival rate in GC patients. Compared to AJCC 8th pTNM staging system, the DCA curve indicate that the nomogram has a higher net income. Conclusion:The nomogram predicting overall survival of patients with stage Ⅰ-Ⅲ gastric cancer is established and verified , which provides better individual prediction than TNM staging system.
RESUMEN
Objective:To investigate the effect of neoadjuvant chemotherapy on the prognosis of gastric neuroendocrine cancer.Methods:This study included 102 patients with gastric neuroendocrine cancer, the disease-free survival rate (DFS) and overall survival rate (OS) were compared between two groups according whether they were given neoadjuvant chemotherapy before radical resection.Results:Ninteen of the 102 patients received neoadjuvant chemotherapy combined with surgery, while the other 83 patients received upfront surgery . The 1-year survival rate of the direct operation group and the NAC group was 83.0% and 51.8%, respectively, and the 3-year survival rate was 63.0% and 33.3%, respectively ( χ2=9.182, P=0.002). The 1-year disease-free survival rate was 80.4% and 38.5%, respectively, and the 3-year disease-free survival rate was 59.8% and 25.7%, respectively ( χ2=11.142, P=0.001). Subgroup analysis showed that the difference between the two groups was mainly significant between MANEC patients ( χ2=10.742, P=0.001). Multivariate analysis showed that neoadjuvant therapy was an independent risk factor affecting the overall survival rate (all P<0.05). Univariate analysis shows that only adjuvant chemotherapy is the risk factor affecting disease-free survival ( P<0.05). When the neoadjuvant chemotherapy and the direct surgery were matched 1∶1, the OS and DFS of the direct surgery group were better than those of the NAC patients ( χ2=4.014, 3.954; P=0.045, 0.047). Conclusion:Neoadjuvant chemotherapy failed to improve the prognosis of patients with gastric neuroendocrine cancer/MANEC.
RESUMEN
Objective:To study the effects of miR-128-3p on the migration and invasion of the gastric cancer cells.Methods:qRT-PCR was used to detect the expression of miR-128-3p in 126 gastric cancer tissues and adjacent tissues from Jan 2014 to Jan 2016 at He'nan Cancer Hospital. The effect of miR-128-3p on the invasion and migration of gastric cancer cell line was detected.The expression of miR-128-3p related proteins was detected by Western blotting, miRNA on-line target prediction tool for the prediction of miR-128-3p directly regulated downstream target genes.Results:the expression of miR-128-3p in gastric cancer was significantly higher than that in adjacent non-tumor tissues ( P<0.05). The expression of miR-128-3p was correlated with the vascular tumor thrombus, pN staging and pTNM staging, the prognosis of patients with high expression of miR-128-3p was poor (all P<0.05). MiR-128-3p expression was significantly higher in gastric cancer cell lines ( P<0.05). Online target prediction tool and double luciferase reporter gene showed that CLDN18 was a downstream target gene directly regulated by mir-128-3p. Conclusion:The high expression of miR-128-3p is related to the poor prognosis of gastric cancer patients.
RESUMEN
Objective:To explore the prognostic value of combined fibrinogen/albumin ratio (FAR) and CA724 in patients with stage Ⅱ/Ⅲ gastric cancer after radical resection.Methods:A total of 932 patients were enrolled in the study, and the best cut-off values of CEA, FAR, NLR and other variables were obtained through ROC curve analysis. According to the FAR-CA724 score, patients were divided into 3 groups: FAR-CA724=0 (CA724<3.43 ng/ml and FAR<0.083), FAR-CA724=1 (CA724≥3.43 ng/ml and FAR≥0.083) and FAR-CA724=2 (CEA≥3.43 ng/ml and FAR≥0.083).Results:After FAR-CA724 grouping, the patient's age (χ 2=12.02, P=0.002), gender (χ 2=15.91, P<0.001), tumor size (χ 2=18.22, P<0.001), hypertension (χ 2=6.35, P=0.042), tumor location (χ 2=26.09, P<0.001), degree of differentiation (χ 2=12.46, P=0.002) and pTNM staging (χ 2=6.68, P=0.035) are significantly different. Survival analysis showed that there were significant differences in OS between the three groups of patients (FAR-CA724=0, 1, and 2: 88.2%, 64.3% and 37.8%, respectively, P<0.001). By multivariate analysis FAR-CA724 is an independent risk factor affecting OS in patients with stage Ⅱ/Ⅲ gastric cancer after radical surgery. Conclusions:Preoperative FAR-CA724 may be a potential blood marker for predicting the prognosis of GC patients.
RESUMEN
Objective:To investigate the value and molecular mechanism of gastric cancer stem cells in invasion and metastasis of gastric cancer.Methods:Gastric cancer stem cells were isolated by spheroid culture method, and the biological characteristics were identified. The role of gastric cancer stem cells in multidrug resistance, invasion and metastasis was analyzed. The important molecules involved in the biological behavior of gastric cancer stem cells were identified by gene chip. Screening of the signaling pathway revealed that anthrax toxin receptor 2 (ANTXR2)plays an important role in invasion, metastasis, glomerization and tumor formation.Results:Sox2 and Bmi1 expression in SGC7901 and MGC803 cells were significantly higher than monolayer culture cells (15.39±3.23). Oct4 express increased to (4.19±0.62). The expression levels of the dry-related genes Bmi1, Sox2 and Oct4 in SGC7901-SC cells were (3.29±0.52), (3.12±0.49), (2.58±0.35), respectively, which were higher than those of SGC7901-MN cells, Bmi1, Sox2 and Oct4, respectively. The differences were statistically significant ( t=5.392, 7.316, 6.449, all P<0.05) for (1.41±0.39), (2.04±0.33), (1.39±0.32); in primary cells XN0422-SC and in SGC7901-SC cells, miR-638 was in high expression (0.69±0.11), and miR-181b and miR-181a in low expression (0.12±0.05) and (0.15±0.07). ANTXR2 expression in SGC7901-SC cells was higher than that in SGC7901-MN cells ( t=6.216, P<0.05). The ANTXR2 positive cells in SGC7901-SC was 85.48%. The proportion of ANTXR2 positive cells in SGC7901 was 4.98%. Gastric cancer cells XN0422 and SGC7901 were affected by PLVT713, and ANTXR2 expression protein decreased. Conclusion:ANTXR effects a regulatory role by activating the Src/ERk signaling pathway, which can be used to predict the biological beharious of gastric cancer.

Cell counting kit-8 (CCK-8) and clone formation were used to detect the changes of proliferation of SGC7901, flow cytometry to detect the changes of SGC-7901 cell cycle, and nude mouse model bearing subcutaneous gastric cancer xenograft was established using SGC-7901 cells with stable ANXA9 knockdown to assess the effect of low expression of ANXA9 on xenograft growth.Results:Immunohistochemistry showed that the expression level of ANXA 9 was 67.1% and 30.7% in gastric cancer tissues and adjacent tissues, respectively. qPCR showed that the expression levels of ANXA 9 mRNA in gastric cancer tissues and adjacent tissues were 0.142±0.107 and 0.819±0.191, respectively. The difference was statistically significant ( P<0.05). The high expression of ANXA9 was different from the low expression group in the degree of tissue differentiation ( P<0.05), and the median survival time was 50 and 59 months, respectively. OD values of the transfected cells were 0.285±0.025, 0.386±0.031, 0.711±0.032, 1.007±0.084, 1.552±0.055 and 0.274±0.026, 0.380±0.049, 0.714±0.035, 1.106±0.081, 1.561±0.060, respectively, compared with 0.294±0.011, 0.445±0.046, 1.076±0.096, 1.588±0.095, 2.286±0.110 in NC group ( P<0.05). Cell clone formation in the transfection group was 207±12 and 225±14, lower than that in the NC group (412±14, P<0.05). After inhibiting the expression of ANXA9, the proportion of G 0/G 1 phase cells in the transfection group was 62.80% and 55.87%, respectively, significantly increased compared with 44.37% in the NC group. The proportions of S-phase cells in the transfected group were 22.74% and 21.44%, respectively, which were significantly lower than that in the NC group 29.19% ( P<0.05), after stable interference with ANXA9, the growth rate of transplanted tumors was significantly slower than that of the control group. On the 23rd day, the average volume of transplanted tumors in the two groups were (625±49) mm 3 and (303±157) mm 3, respectively, and the mass of tumor tissues in the two groups were (1.60±0.11) and (0.57±0.09) g ( P<0.05). Conclusions:Down-regulation of ANXA9 expression can inhibit the proliferation of gastric cancer cells and the ability of subcutaneous tumor formation in nude mice.
RESUMEN
Objective To investigate the effect of the first surgical treatment on progression-free survival (PFS)time of retroperitoneal liposarcoma and the prognosis.Methods We analyzed the clinical data of 74 cases of retroperitoneal liposarcoma from 1998 to 2016 in He'nan Cancer Hospital (Zhengzhou University Affiliated Tumor Hospital Department of General Surgery).Results The results demonstrated that progression-free survival time of the first surgical resection of retroperitoneal liposarcoma in patients related with tumor necrosis (P < 0.001),lobulated tumor (P < 0.001),symptoms (P =0.013),Ro resection (P =0.003),distant metastasis (P =0.028),postoperative chemotherapy (P =0.006) and tumor differentiation (P < 0.001).Progression-free survival time was not correlated with gender,age of first diagnosis,the invasion of adjacent organs,tumor size,operation time and combined organ resection (all P>0.05).The rate of 1-year,3-year,5-year survival time attached to PFS≤24 m and PFS >24 m were 93.7% vs.94.7,90.5% vs.80.9%,58.4% vs.74.8%(P=0.111).Conclusion The first attempt of radical resection determines progression-free survival of retroperitoneal liposarcoma,however,patients' PFS was not related with their overall survival.

RESUMEN
Objective To report a new approach of splenic hilar lymph nodes dissection in radical gastrectomy for gastric cancer. Methods 193 cases of gastric cancer patient receiving radical resection of gastric cancer between May 2008 and October 2008 were studied. The tail and body of spleen and pancreas were thoroughly freed with retroperitoneal way retrogressively and extruded out of abdominal cavity in 80 cases. The other 113 cases received operation with routine way. Results In 80 cases who received operation with retroperitoneal approach retrogressively, the total splenic hilar lymph nodes were 519, the positive ones were 65, the positive rate was 12.5 %; In the other 113 cases the total splenic hilar lymph nodes were 565, the positive ones were 58, the positive rate was 10.3 %. The positive rate had statistic significance between these two groups. Conclusion Extruded splenic hilar lymph nodes dissection with retroperitoneal approach retrogressively is safe and has the same effect with splenectomy in gastric cancer operation.
