Relationship between the inflammatory-nutritional index and recurrence and prognosis in patients with ;gastric cancer / 实用医学杂志

ABSTRACT

Objective To investigate the correlation between the inflammatory-nutritional index (INI) and recurrence and prognosis in patients with gastric cancer. Methods A total of 78 cases patients of gastric cancer with recurrence and 64 cases without recurrence were enrolled. INI was calculated by the ratio of serum albumin and C-reactive protein. The value of INI predicting recurrence was analyzed using receiver operating characteristic curve (ROC). According to this value, the Kaplan-Meier curves and Cox regression analysis were used to evaluate the effect of INI on prognosis. Results Compared with the control group, the recurrence group showed smaller INI, larger tumors, lower degree of differentiation, deeper invasion and higher TNM stage, the differences were statistically significant (all P < 0.01); The INI significantly predicted the recurrence of gastric cancer, with a sensitivity of 62.5%, specificity of 79.5% and critical value of 0.36 (P < 0.01); Additionally, The pathological features were worse in the low INI group than the high INI group , the differences were statistically significant (P < 0.01); The INI significantly predicted the prognosis of gastric cancer, with a sensitivity of 65.9%, specificity of 66.8% and the critical value of 0.34 (P < 0.01); Obviously, the survival rate was lower in the low INI group than the high INI group (48.8% vs 25.0%, P < 0.01). Furthermore, INI was an independent risk factor for prognosis of gastric cancer (OR = 1.78, 95% CI 1.34 ~ 2.59, P < 0.01). Conclusion The INI is closely related to the characteristics of gastric cancer, it is an effective marker to predict recurrence and prognosis of gastric cancer.
