Capillary invasion (CI) offers been found to play a significant part in metastasis and recurrence of gastric adenocarcinoma (GAC). stratified by TNM stage, the prognosis of CI (+) group in stage III was remarkably even worse than CI (?) group (= 0.006), as the differences were not significant in stage ICII and stage IV (both 0.05). The nomograms indicated that (-)-Epigallocatechin gallate manufacturer CI was part of the individual prognostic prediction system. The predictive accuracy of CI and other characteristics was better than TNM alone ( 0.001). Our finding suggested that CI was an independent prognostic factor in patients with GAC, and the nomogram based on CI and other clinicopathological factors was a valuable and accurate tool in individual prognostic prediction. = 0.020), poorly/undifferentiated differentiation grade ( 0.001), larger tumor size ( 0.001), more (-)-Epigallocatechin gallate manufacturer advanced macroscopic type ( 0.001) and TNM stage ( 0.001) than those with CI (?). On the other hand, the relationship between CI (+) and age (= 0.451), gender (= 0.934) was not found. To identify the independent risk factors for CI, multivariate analyses (-)-Epigallocatechin gallate manufacturer were performed in our study (Table ?(Table2).2). By logistic regression analysis, we found that CI was significantly correlated to differentiation grade (= 0.009) and pN stage ( 0.001). Table 1 Comparison of clinicopathological features between capillary invasion (CI) positive and negative group value= 227 (%)= 1171(%)value= 662, 47.4%), stage III (= 655, 46.9%) and stage IV (= 81, 5.7%). The rates of CI (+) were 8.8%, 22.0% and 30.9% in TNM ICII, III and IV subpopulation respectively. In the subgroup of TNM stage ICII, we found that there were more tumors with poorly differentiation grade (= 0.026), more advanced pT stage ( 0.001) and pN stage (= 0.013) in CI (+) group than those in CI (?) group (Table ?(Table3).3). With regard to TNM stage III subgroup, the results demonstrated that there were more patients with N2 and N3 stage ( 0.001) tumors in CI (+) group than those in CI (?) group. However, in TNM IV subgroup, there were no significant differences between patients with CI (+) and CI (?).

Patients with CI (+) had significant worse prognosis than those with CI (?) in Kaplan-Meier analysis ( 0.001, Figure ?Figure1).1). Additionally, we performed multivariate analysis with Cox regression to further evaluate the prognostic significance of CI and other clinicopathological factors (Table ?(Table4),4), and we found that CI (= 0.023, HR = 1.270, 95% confidence interval [1.034?1.560]) was an independent prognostic factor, as well as other clinicopathological factors like age (= 0.002), tumor size ( 0.001) and TNM stage ( 0.001). Table 4 Univariate and multivariate Cox analysis for prognostic factors valuevalue= 0.006, Figure ?Figure2)2) was significantly worse than that of CI (?) group, while in stage ICII (= 0.556, Figure ?Figure3)3) and stage IV (= 0.904, Figure ?Figure4),4), the difference wasn’t remarkable.

Open in a separate window Figure 4 Survival analysis between TNM ICII stage patients with CI (+) and CI (?) Nomogram based on CI We also used nomogram to predict 3-year overall survival rate of individual patients. Age, tumor size, TNM stage and CI (= 0.015, hazard ratio 1.292, 95% confidence interval: 1.052, 1.587) were selected in the nomogram (Shape ?(Shape5).5). The nomograms indicated that CI was area of the specific prognostic prediction program. The outcomes of the nomograms had been comparable to those of aforementioned multivariate analyses. The calibration curves of nomograms demonstrated that the predictive possibility of 3-yr survival was extremely carefully to the real 3-yr survival (Shape ?(Figure66).

The C-indexes of nomograms had been 0.718 (95% CI 0.696 0.740), weighed against 0.689 (95% CI 0.669, 0.709) of TNM staging system. The variations between nomograms and TNM staging program were significant ( 0.001). Dialogue CI included lymphatic invasion and/or venous.
