[Predictive and Prognostic significance of high-sensitivity modified Glasgow Prognostic Score (HS-mGPS) in advanced gastric cancer patients treated with neoadjuvant chemotherapy].

To study the predictive and prognostic significance of high-sensitivity modified Glasgow Prognostic Score (HS-mGPS) on the effect of neoadjuvant chemotherapy for advanced gastric cancer. 117 patients with advanced gastric cancer received neoadjuvant chemotherapy with SOX (oxaliplatin+ S1) or mFOLFOX 6(oxaliplatin+ CF+ 5-FU) regimen. HS-mGPS was calculated according to blood C-reactive protein (CRP) concentration and serum albumin (ALB) level. The correlation between HS-mGPS and clinicopathological characteristics was determined and the predictors of survival were analyzed. 117 patients with stage ⅡB (43 cases), stage Ⅲ (60), and stage Ⅳ (14) received preoperative neoadjuvant chemotherapy. The overall response rate of neoadjuvant chemotherapy was 61.5%(72/117), and the tumor control rate was 88.0% (103/117), with a pathological response rate of 91.5% (107/117). The R0 resection rate was 81.2% (95/117). The median disease-free survival (DFS) was 21.0 (95% 6.4-35.6) months. The median overall survival (OS) was 39.0 (95% 21.4-56.6) months. Higher HS-mGPS was associated with higher T stage, local lymph-node metastasis, distant metastasis, lower chemotherapy overall response rate and lower pathological response rate (all <0.05). The univariate analysis and multivariate analysis showed that higher HS-mGPS, presence of local lymph-node metastasis and non R0 resection were associated with poorer DFS and OS (<0.05). HS-mGPS can be used to predict the benefits of neoadjuvant chemotherapy and as an independent prognostic factor for survival in patients with advanced gastric cancer.
