Postoperative ratio of the maximum C-reactive protein level to the minimum peripheral lymphocyte count as a prognostic indicator for gastric cancer patients

Inflammation, together with immune and nutritional status, are associated with the progression of various cancer types. We evaluated the prognostic significance of the postoperative ratio (post-CLR) of the maximum C-reactive protein value (post-CRPMax) to the minimum peripheral lymphocyte count (post-LCMin) in patients with gastric cancer (GC).
The subjects of this retrospective study were 227 patients who underwent curative surgery for histopathologically diagnosed gastric adenocarcinoma.
The 5-year overall survival (OS) rates differed significantly between the post-CLRHigh (≥ 152.6) group and the post-CLRLow (< 152.6) group for all patients (45.0% vs. 68.4%, respectively; P < 0.001). The 5-year disease-specific survival (DSS) rates were also significantly related to post-CLR for all patients, (80.6% vs. 64.3% for the post-CLRLow and the post-CLRHigh groups, respectively; P = 0.002). Among patients without infectious complications, the CLR affected both the 5-year OS rate (48.4% vs. 69.2% for the post-CLRHigh and the post-CLRLow groups, respectively; P = 0.006) and the 5-year DSS rate (80.2% vs. 67.0% for the post-CLRLow and the post-CLRHigh groups, respectively; P = 0.027). Multivariate analysis revealed that post-CLR was an independent prognostic indicator for both the OS and DSS of all patients.
Our finding show that the post-CLR can help predict the prognosis of GC patients.
