The prognostic significance of preoperative platelet-to-lymphocyte ratio and interleukin-6 level in non-muscle invasive bladder cancer.

Preoperative peripheral blood inflammatory markers (PLR and IL-6) are useful predictors of RFS in NMIBC patients at the time of initial diagnosis. High PLR and high IL-6 were identified as independent risk factors for tumor recurrence and could serve as potential biological markers for prediction of NMIBC recurrence.
