Preoperative Measurement of the Modified Glasgow Prognostic Score Predicts Patient Survival in Non-Metastatic Renal Cell Carcinoma Prior to Nephrectomy.

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.

Incidence of urethral stricture after bipolar transurethral resection of the prostate using TURis: results from a randomised trial.

OBJECTIVES: To assess whether bipolar transurethral resection of the prostate (B-TURP) using the TURis system has a similar level of efficacy and safety to that of the traditional monopolar transurethral resection of the prostate (M-TURP), and to evaluate the impact of the TURis system on postoperative urethral stricture rates over a 36-month follow-up period. PATIENTS AND METHODS: A total of 136 patients with benign prostatic obstruction were randomised to undergo either B-TURP using the TURis system or conventional M-TURP, and were regularly followed for 36 months after surgery. The primary endpoint was safety, which included the long-term complication rates of postoperative urethral stricture. The secondary endpoint was the follow-up measurement of efficacy. RESULTS: In peri-operative findings, no patient in either treatment group presented with transurethral resection syndrome, and the decline in levels of haemoglobin and hematocrit were similar. The mean operation time was significantly extended in the TURis treatment group compared with the M-TURP group (79.5 vs 68.6 min; P = 0.032) and postoperative clot retention was more likely to be seen after M-TURP (P = 0.044). Similar efficacy findings were maintained throughout 36 months, but a significant difference in postoperative urethral stricture rates between groups was detected (6.6% in M-TURP vs 19.0% in TURis; P = 0.022). After stratifying patients according to prostate volume, there was no significant difference between the two treatment groups with regard to urethral stricture rates in patients with a prostate volume ≤ 70 mL (3.8% in M-TURP vs 3.8% in TURis), but in the TURis group there was a significantly higher urethral stricture rate compared with the M-TURP group in patients with a prostate volume >70 mL (20% in TURis vs 2.2% in M-TURP; P = 0.012). Furthermore, the mean operation time for TURis was significantly longer than for M-TURP for the subgroup of patients with a prostate volume > 70 mL (99.6 vs 77.2 min; P = 0.011), but not for the subgroup of patients with a prostate volume ≤ 70 mL. CONCLUSION: The TURis system seems to be as efficacious and safe as conventional M-TURP except that there was a higher incidence of urethral stricture in patients with larger preoperative prostate volumes.

The combination of preoperative platelet count and neutrophil lymphocyte ratio as a prognostic indicator in localized renal cell carcinoma.

INTRODUCTION: The combination of platelet count and neutrophil to lymphocyte ratio (COP-NLR) has been shown to provide prognostic information in several cancers, whereas its prognostic value in renal cell carcinoma (RCC) has not been reported. The objective of the present study was to examine the preoperative prognostic value of the COP-NLR in patients with localized RCC undergoing nephrectomy. MATERIAL AND METHODS: The record of 268 patients, who underwent nephrectomy due to a diagnosis of RCC at our institute was analyzed in the study. The cut-off value of platelet count and NLR were defined by receive operating characteristic (ROC) analysis and the areas under the curve (AUC). Patients with both an increased platelet count (> 310×109/l) and an elevated NLR (> 3.85) were assigned to the score 2, and patients with one or neither of these indicators were assigned to the score 1 or 0, respectively. The impact of the COP-NLR and other clinicopathological characteristics on overall survival (OS) and recurrence-free survival (RFS) were evaluated using the univariate and multivariate Cox regression analysis. RESULT: The median follow-up duration after surgical resection was 60 months. Multivariate analysis using the 10 clinicopathological findings selected by univariate analyses demonstrated that the preoperative COP-NLR was an independent prognostic factor for OS (HR: 2.32, 95%CI: 1.22 to 4.26, p=0.011) and RFS (HR: 1.91, 95%CI: 1.02 to 3.53, p=0.044). CONCLUSION: The findings of the current study suggested that the preoperative COP-NLR is an independent prognostic indicator of OS and RFS for patients with localized RCC.
