(Annals of Medical Research, 2021) Kölükçü, Engin; Ozbek, Latif Mustafa; Unsal, Velid
Aim: Active surveillance is a highly emphasized approach to low-risk prostate cancer. Upgrading and upstaging should be evaluated carefully in this strategic management. This study aimed to analyze the relationship of neutrophil-lymphocyte ratio (NLR) with these two clinical conditions. Materials and Methods: Demographic data, prostate-specific antigen (PSA) levels, prostate volumes, NLR, disease stages, and Gleason scores of 59 low-risk prostate cancer patients who underwent radical prostatectomy and met active surveillance criteria were evaluated in our clinic. The patients were examined in four groups according to their postoperative pathology specimens. Accordingly, the patients with upgrading Group 1, while those without formed Group 2. Similarly, Group 3 consisted of the cases with upstaging and the patients with no upstaging were determined as Group 4. Results: Median age, PSA levels, prostate volumes, neutrophil and lymphocyte counts of the patients were 69.0 (63.0-72.0) years, 7.24 (5.50-8.90) ng/dL, 65.0 (60.0-65.0) cc, 6.40 (4.87-8.73) K/uL, and 2.50 (1.60-3.10) K/uL, respectively. Prostate volume and age distribution were similar between the groups. PSA levels were higher in Group 1 and Group 3 than those in Group 2 and Group 4 (p=0.012 and p=0.049, respectively). NLR was 3.54 (1.89-5.45) and 1.94 (1.68-3.76) in groups 1 and 2, respectively. Although these values were low in Group 2, a statistically significant relationship could not be established (p=0.266). NLR in groups 3 and 4 was 2.46 (1.52-5.45) and 2.24 (1.68-4.35), respectively. The NLR level in Group 3 was high; however, the difference was not statistically significant (p=0.953). Conclusion: The study let us to conclude that NLR alone is not sufficient to predict the clinical course of patients with low-risk prostate cancer.
Clinical Significance of Preoperative Neutrophil to Lymphocyte Ratio in Organ-Confined Urothelial Bladder Cancer
(2021) Ozbek, Latif Mustafa; Unsal, Velıd; Demir, Osman; Kölükçü, Engin
We aimed to investigate the relationship between the preoperative neutrophil to lymphocyte ratio (NLR) and the postoperative tumor stage and grade in patients with organ- confined urothelial bladder cancer. We examined 308 patients who underwent transurethral resection in our clinic. Our study only included patients whose pathology results were organ-confined urothelial bladder cancer. The patients were classified according to tumor stage (Ta, T1, and T2) and tumor grade (Grade 1 and 2, indicating a low-grade; Grade 3, referring to a high-grade). Then each group was compared within itself based on the NLR evaluated before the surgery. A total of 279 cases (90.6%) were male. The mean age, tumor size, neutrophil and lymphocyte counts of the patients were 69.33±10.92 years, 2.99±2.35 cm, 5.36±1.99 K/uL, and 2.23±0.78 K/uL, respectively. Inflammation parameters regarding the cancer stage were as follows: NLR was 2.08, 2.36, and 3.07, for Ta, T1, and T2 tumors respectively. The relationship between T1 and T2 tumors and Ta and T2 tumors was significant (p <0.001, p <0.001). But there was no significant difference between the Ta and T1 tumors (p: 0.142). NLR was 2.07 and 2.78 for low- and high-grade tumors, respectively. These values were statistically significant (p <0.001). We could not statistically correlate between Ta and T1 tumors. However, based on the other positive correlations we have obtained, we think that NLR evaluated before transurethral resection may be a valuable parameter in predicting the operative pathology result.
