Purpose
The modified Glasgow Prognostic Score (mGPS) by measurement of serum C-reactive protein and albumin levels has been shown to provide prognostic value in various cancer types. The purpose of this study was to evaluate whether preoperative assessment of the mGPS predicts patient survival outcome in renal cell carcinoma (RCC).
Materials and Methods
Clinicopathological and follow-up data in 219 RCC patients, all of whom underwent curative or non-curative nephrectomy, were collected. Overall survival (OS) and cancer-specific survival (CSS) after nephrectomy were evaluated, and univariate and multivariate analyses were conducted to assess the predictive value of the variables, including the mGPS.
Results
During the median follow-up of 57 months, 53 patients (24.2%) were deceased within 22 months of the median OS. The 5-year OS rate from nephrectomy was 85.9 and 18.8% in non-metastatic (n = 195) and metastatic (n = 24) patients, respectively. Increasing mGPS was associated with shorter OS in non-metastatic patients (2-year OS rate of 98.2% in mGPS0, 73.3% in mGPS1, and 44.4% in mGPS2; hazard ratio [HR] 9.96, 95% confidence interval [CI] 4.88–20.13, p < 0.001), whereas no significant difference in OS according to the mGPS was seen in metastatic patients (HR 2.01, 95% CI 0.79–5.16, p = 0.137). On multivariate analysis, the mGPS remained as an independent predictor for OS (HR 5.24, 95% CI 1.39–19.77, p = 0.015) and CSS (HR 4.69, 95% CI 1.13–20.96, p = 0.034) in non-metastatic RCC patients.
Conclusions
The mGPS appeared to be a reliable, preoperatively defined predictive marker with widely standardized protocol in non-metastatic RCC, and should therefore be considered in treatment decision making for RCC patients.
