Abstract
INTRODUCTION
Muscle-infiltrating bladder tumor (MIBT) has a recurrence-free survival (RFS) of 50% at 5 years. Although neoadjuvant chemotherapy (NCT) has increased it by 8%, which group of patients benefits the most from this treatment remains unclear.
OBJECTIVE
Evaluate the prognostic value of immune-nutritional status in patients with MIBT who are candidates for cystectomy, and to develop a score that allows identifying patients with a worse prognosis (pT3-4 and/or pN0-1).
MATERIAL AND METHODS
A retrospective analysis was carried out on 284 patients with MIBT treated with radical cystectomy. Preoperative laboratory tests were analyzed and immune-nutritional indices were calculated. The Kaplan-Meier method was used to calculate the PFS. Cox regression was used for multivariate analysis.
RESULTS
Univariate analysis showed a statistically significant relationship with leukocyte/lymphocyte index (p = 0.0001), neutrophil/lymphocyte index (p = 0.02), prognostic nutritional index (p = 0.002), and platelet/lymphocyte ratio (p = 0.002). In multivariate analysis, the leukocyte/lymphocyte ratio (p = 0.002) and PNI (p = 0.04) behaved as independent prognostic factors of decreased RFS. Based on these, a prognostic score was developed to classify patients into 3 prognostic groups. Eighty percent of patients with pT3-4 and/or pN0-1 tumors were in the intermediate-poor prognostic groups.
CONCLUSION
The implementation of a precystectomy immune-nutritional score in clinical practice would help in the selection of a group of patients with a more unfavorable pathologic stage and worse PFS. We believe that these patients could benefit more from a NACT.
