RLC score (R status, lymphovascular invasion, C-reactive protein) predicts survival following radical cystectomy for muscle-invasive bladder cancer

Abstract Background CRP-based scoring systems were found to correlate with survival in patients with urooncologic diseases. Our retrospective single-centre study aimed to confirm CRP as a prognostic parameter in patients with bladder cancer (BCa) undergoing radical cystectomy (RC) and, based on the findings, to develop our own outcome score for muscle-invasive bladder cancer (MIBC) patients undergoing RC in order to identify patients with a high risk of mortality. Material and methods A total of 254 patients who underwent RC at Hanover Medical School between 1996 and 2007 were reviewed with a follow-up until autumn 2013. The clinicopathologic parameters assessed included age, co-morbidities, pre-/postoperative serum levels of CRP, leukocytes, haemoglobin, creatinine, urinary diversion, tumour grading, staging, lymph node status, lymph node density (LND), lymphovascular invasion (LVI), metastases, and resection margin status. The Chi-square test was used for univariate analyses. Kaplan-Meier estimates and the log-rank test were used for survival analyses. Regarding outcome, overall survival (OS) was assessed. Results The multivariate analysis excluding lymph node (LN)-positive and metastatic patients at time of RC showed a significant association of R status (R; p < 0.001), LVI (L; p = 0.021) and preoperative CRP level > 5 mg/l (C; p = 0.008) with OS. Based on these parameters, the RLC score was developed. The median OS in the intermediate, high-risk and very high-risk groups according to the RLC score was 62, 22, and 6.5 months, respectively. The score had a high predictive accuracy of 0.752. Conclusion The RLC score identifies BCa patients at a higher risk of overall mortality after RC. Overall, our study supports the role of CRP in prognostic score models for BCa.

Introduction: Radical cystectomy (RC) is the main treatment option for patients with muscle-invasive bladder cancer (MIBC) and non-muscle-invasive bladder cancer (NMIBC), which carry the highest risk of progression. In this study, we investigated the effect of time from transurethral resection of the bladder (TUR-B) to cystectomy on lymph node positivity, cancer-specific survival and overall survival in patients with MIBC. Methods: The records were reviewed of 530 consecutive patients who had RC and pelvic lymphadenectomy procedures with curative intent performed by selected surgeons between May 2005 and April 2016. Our analysis included only patients with transitional cell carcinoma of the bladder; we excluded 23 patients with other types of tumor histology. Results: Patients who underwent delayed RC were compared with patients who were treated with early RC; both groups were similar in terms of age, gender, T stage, tumor grade, tumor differentiation, lymph node status and metastasis status. However, when both groups were compared for disease-free survival and overall survival, patients of the early-RC group had a greater advantage. Conclusions: The optimal time between the last TUR-B and RC is still controversial. A reasonable time for preoperative preparation can be allowed, but long delays, especially those exceeding 3 months, can lead to unfavorable outcomes in cancer control.
