Background: The local and systemic inflammatory responses provide prognostic information in cancer. The modified Glasgow Prognostic Score (mGPS) provides additional prognostic information than C-reactive protein (CRP) alone when assessing the systemic inflammation in cancer. The aim of this study was to determine the role of local and systemic inflammation in renal cancer.
Methods: The cohort consisted of 79 patients who had undergone potential curative resection. Systemic inflammation, mGPS, was constructed by measuring preoperative CRP and albumin concentrations and the Klintrup-Makinen score was evaluated histologically for the local inflammatory response. Pathological parameters such as T stage, grade and tumour necrosis were also assessed. The local inflammatory response was assessed by examining all inflammatory cells at the tumour edge on diagnostic haematoxylin and eosin slides.
Results: On univariate analysis, T stage (p < 0.001), grade (p = 0.044) and mGPS (p < 0.001) were significant predictors of cancer-specific survival. On multivariate analysis, mGPS (hazard ratio 8.64, 95% confidence interval 3.5-21.29, p < 0.001) was the only significant independent predictor of cancer-specific survival.
Conclusion: A preoperative systemic inflammatory response as measured by the mGPS is an independent predictor of poor cancer-specific survival in renal cancer in patients undergoing potential curative resection.
