According to the data in this study, it can be said that Ta-T1 tumors are likely to be invasive by 50% if the NLR value is greater than 3.96.

Background: The aim of this study was to research the importance of the neutrophil to lymphocyte ratio (NLR) in prediction of PSA recurrence after radical prostatectomy, which has not been reported so far. Materials and Methods: The data of 175 patients who were diagnosed with localised prostate cancer and underwent retropubic radical prostatectomy was retrospectively examined. Patient pre-operative hemogram parameters of neutrophil count, lymphocyte count and NLR were assessed. The patients whose PSAs were too low to measure after radical prostatectomy in their follow-ups, and then had PSAs of 0,2 ng/mL were considered as patients with PSA recurrence. Patients with recurrence made up Group A and patients without recurrence made up Group B. Results: In terms of the power of NLR value in distinguishing recurrence, the area under OCC was statistically significant (p<0.001) .The value of 2.494 for NLR was found to be a cut-off value which can be used in order to distinguish recurrence according to Youden index. According to this, patients with a higher NLR value than 2.494 had higher rates of PSA recurrence with 89.7% sensitivity and 92.6% specificity. Conclusions: There are certain parameters used in order to predict recurrence with today's literature data.We think that because NLR is easy to use in clinics and inexpensive, and also has high sensitivity and specificity values, it has the potential to be one of the parameters used in order to predict biochemical recurrence in future.

Objectives: To determine whether there is a correlation between high Gleason score and free/total (f/t) prostate specific antigen (PSA) in patients newly diagnosed with prostate carcinoma. Materials and Methods: The study included 272 prostate biopsy patients whose total PSA value ranged from 4 - 10 ng/ml. The patients were divided into 2 groups according to the f/t PSA ratio: Group 1 ≤ 15% and Group 2 > 15%. Furthermore, the groups were also compared to each other in terms of mild (≤ 6), moderate (= 7), and high (≥ 8) Gleason score. Results: Group 1 consisted of 135 (49.6%) patients and Group 2 consisted of 137 (50.4%) patients. While 27 (20%) patients had a high Gleason score in Group 1, only 10 (7.3%) patients had a high Gleason score in Group 2 (p = 0.008). Using Spearman's correlation test, we found that the f/t PSA ratios were observed to decrease significantly in all patients with increased Gleason scores (p = 0.002, r = -0.185). Conclusion: According to our study, there is a relationship between higher Gleason score and decreased f/t PSA ratio. Therefore, f/t PSA can be an indicator for predicting the Gleason score.
