Purpose
Gastric cancer (GC) is a common malignancy, especially in East Asian countries. There is emerging evidence that circulating neutrophil and platelet levels correlate with cancer progression. We evaluated the short- and long-term outcomes of GC patients systemically, to compare the original neutrophil–platelet score (NPS) and our modified NPS (mNPS).
Methods
We analyzed the original pre-operative NPS and the mNPS of 621 GC patients.
Results
Racial differences between the United Kingdom and East Asian countries accounted for compelling deviation in classification using the original NPS, which could not reliably stratify the prognoses of Japanese GC patients. We developed the mNPS using appropriate cutoff levels for pre-operative neutrophils and platelets, and demonstrated that the pre-operative mNPS was significantly correlated with all of the well-established clinicopathological factors for disease development, including advanced T stage, venous and lymphatic vessel invasion, lymph node/peritoneal /distant metastasis, and tumor-node-metastasis stage. The pre-operative mNPS could stratify prognostication for both overall survival (OS) and disease-free survival (DFS): a high pre-operative mNPS was an independent prognostic factor for the OS and DFS of GC patients and also an independent predictor of post-operative surgical site infection after gastrectomy.
Conclusion
Calculating the mNPS could help clinicians to stratify the surgical and oncological risks of patients with GC.
