In the study of Bauzá Quetglas et al. [46] on 80 tCa patients undergoing orchiectomy, no correlation was observed between NLR and conventional tumor markers (AFP and B-HCG) at both pre-orchiectomy (r value = 0.08 and 0.06, respectively) and post-orchiectomy (r value = 0.12 and 0.07, respectively) assessments. The gene discussed is AFP; the disease is neoplasm.
