title: Comparison of the prognostic value of inflammation-based pathologic and biochemical criteria in patients undergoing potentially curative resection for colorectal cancer.
abstract: OBJECTIVE
  To examine interrelationships between the local inflammatory response (Klintrup and Jass scores) and the systemic inflammatory response (Glasgow prognostic score [GPS]), and compare their prognostic value in patients undergoing curative resection for colorectal cancer.
  
  
  BACKGROUND
  Both localized peritumoral inflammatory cell infiltrate and the host systemic inflammatory response are known to have prognostic value in colorectal cancer. However, the interrelationships of biochemical and cellular components of the systemic inflammatory response and the local inflammatory response are poorly understood.
  
  
  METHODS
  Retrospective study of 287 patients who underwent surgery between 1997 and 2004. Data were collected from routine preoperative blood tests. Routine pathology specimens were scored according to Jass and Klintrup criteria for peritumoral infiltrate.
  
  
  RESULTS
  Increased Dukes stage was associated with less peritumoral infiltrate (Jass criteria: P < 0.001, Klintrup criteria: P < 0.01). Increased modified GPS (mGPS) was associated with increased circulating white cell (P < 0.01) and neutrophil (P < 0.01) counts and low lymphocyte counts (P < 0.01). Increased circulating white cell count was associated with increased neutrophil count (P < 0.001) and low-grade peritumoral infiltrate (P < 0.05, Klintrup criteria). Jass and Klintrup criteria for peritumoral infiltrate were directly associated (P < 0.001). On univariate survival analysis of patients with node-negative disease (Dukes A and B), age (P < 0.01), mGPS (P < 0.01), neutrophil count (P < 0.05), and Klintrup criteria (P < 0.05) were associated with cancer-specific survival. On multivariate survival analysis in node-negative disease, the mGPS (hazard ratio: 2.61, 95% CI: 1.27-5.35, P < 0.01) and Klintrup criteria (hazard ratio: 6.31, 95% CI: 1.40-28.44, P < 0.05) were independently associated with cancer-specific survival.
  
  
  CONCLUSIONS
  The results of the present study suggest low peritumoral infiltrate (Klintrup criteria) and increased systemic inflammation (mGPS criteria) are linked through the cell-mediated immune system. Furthermore, both pathologic (Klintrup) and biochemical (mGPS) measures of the inflammatory response predict survival after colorectal cancer surgery.
