Assessment of Utility of Immunohistochemical Marker Prostein for Evaluation of Primary and Metastatic Prostatic Carcinomas

Background: To assess utility of immunohistochemical marker prostein for evaluation of primary and metastatic prostatic carcinomas.Methods:Fifty- six samples of clinically suspected carcinoma prostate was included. Immunohistochemistry (IHC) was performed for assessment of Prostein (P501S). The intensity of positivity was scored from 0 to 3 as follows: score 0 = non-stained; score 1 = weak; score 2 = moderate; and score 3 = strong. The percentage of positively stained cells for each staining intensity was estimated in the respective lesions.Results:Age group 18-28 years comprised of 6 patients, 28-38 years had 12, 38- 48 years had 16 and >48 years had 22 cases. Type of cases were normal prostatic epithelium in 11, benign prostate hyperplasia in 23, HGPIN in 10, primary prostatic adenocarcinoma in 7 and metastatic prostatic adenocarcinoma in 5 cases. Prostein expression was seen in 100% in normal prostatic epithelium with intensity score of 1.8-2.1, benign prostate hyperplasia having 2-2.7, HGPIN with 2-2.3, primary prostatic adenocarcinoma having 1-1.6 and metastatic prostatic adenocarcinoma with 0.8-1.4 intensity score. Conclusion:Prostein is a new prostate specific marker which showed 100% sensitivity and specificity to identify normal and prostatic lesions.

The Values of Systemic Immune-Inflammation Index and Neutrophil–Lymphocyte Ratio in the Localized Prostate Cancer and Benign Prostate Hyperplasia: A Retrospective Clinical Study

PurposeTo evaluate the diagnostic values of systemic immune-inflammation index (SII) and neutrophil–lymphocyte ratio (NLR) in patients with localized prostate cancer (PCa).MethodsBetween January 2014 and December 2019, 117 patients with benign prostate hyperplasia (BPH) and 278 patients with localized PCa who underwent radical prostatectomy (RP) were included in this study. The inflammatory markers including SII, NLR, platelet–lymphocyte ratio (PLR), lymphocyte–monocyte ratio (LMR), lymphocyte ratio (LR), neutrophil ratio (NR), mean platelet volume (MPV), and red cell distribution (RDW) of these two groups were examined and analyzed. ROC curve analysis was performed to assess the discriminative ability of inflammatory markers and their combination with tPSA for PCa. The binary logistic regression model was used to evaluate the association between significant inflammatory markers and risk of PCa.ResultsThe pathological results from RP specimen comprised 72 (25.90%) patients with pT1, 168 (60.43%) patients with pT2, and 38 (13.67%) patients with pT3. According to Student’s t test, patients with PCa had higher NLR (p = 0.034), SII (p = 0.008), and NR (p = 0.004), and lower LR (p = 0.025), MPV (p = 0.003), and TPV (p = 0.022) compared with patients with BPH; the distribution of age, PLR, LMR, RDW, f/t PSA ratio, and BMI did not show any significant differences. The AUC for NLR, SII, NR, and tPSA was 0.697 (p = 0.015), 0.719 (p < 0.001), 0.647 (p = 0.009), and 0.708 (p < 0.001), with threshold values of 1.6, 471.86, 65.15%, and 12.89 ng/ml, respectively. Patients were divided into two groups according to the threshold values, respectively. By using the multivariable logistic regression models, NLR ≥ 1.6 (OR, 2.731; 95% CI, 0.937–7.961, p = 0.042), SII ≥ 471.86 (OR, 1.274; 95% CI 0.473–3.433; p = 0.033), and PSA ≥ 12.89 ng/ml (OR, 1.443; 95% CI, 0.628–3.944; p = 0.014) were independent risk factors associated with PCa. The AUC for combination of NLR, SII, and NR with tPSA was 0.705 (p < 0.001), 0.725 (p < 0.001), and 0.704 (p < 0.001), respectively.ConclusionThis study demonstrated that SII, NLR, and NR were all independent risk factors of PCa. These factors alone could provide better screen methods for PCa before biopsy. In addition, SII is a more powerful tool among these three inflammatory markers associated with PCa. Besides, combination of SII and NLR with tPSA had not much advantage compared with themselves alone.

The Predictive Factor for Favorable Outcome after Surgical Treatment of Benign Prostate Hyperplasia Performed by Young Urologist: Is Surgical Modality Important in Beginner Urologists?

Objective: To identify predictive factors for favorable outcomes after surgical treatments that were performed by beginner urologists in patients with benign prostate hyperplasia (BPH), we retrospectively evaluated outcomes after holmium laser enucleation of the prostate (HoLEP) and transurethral resection of prostate (TURP) that were performed by two young urologists.Methods: Of 80 patients who were treated with HoLEP or TURP, 31 (HoLEP) and 36 (TURP) patients who were followed up for 3 months were enrolled in this study. Preoperative and perioperative variables were evaluated to identify predictive factors for favorable outcome after surgical treatment for BPH.Results: At 3 months postoperative after HoLEP or TURP, the median decrease in International Prostate Symptom Score (IPSS) was 13.0. Patients whose IPSS decreased by over 13 points were categorized into a favorable response group after HoLEP or TURP. Univariate and multivariate logistic regression analyses were performed to identify predictors of favorable outcomes at 3 months after HoLEP or TURP, and the preoperative IPSS was identified as an independent predictor for favorable outcomes.Conclusion: When young urologists plan to perform surgical treatment for BPH, they should consider that the severity of symptoms is the most important factor for favorable outcomes. The type of surgical modality for managing BPH is less important.

Literature Review : Pengaruh Tekhnik Relaksasi Benson Terhadap Nyeri Pada Pasien Post Operasi Benigna Prostat Hyperplasia

Benign Prostatic Hyperplasia (BPH) is a progressive enlargement of the prostate gland that can be treated surgery, As a result of the surgery, the patient will usually feel pain. To overcome it, Benson’s relaxation technique could be applied. This relaxation is an action to free mentally and physically from tension and stress so that it can increase tolerance to pain. This study aims to examine the effect of Benson’s relaxation technique on pain in patients with postoperative benign prostate hyperplasia. Since it is a literature review, it has reviewed three articles taken from Google scholar with Benson’s relaxation, pain, and postoperative BPH as the keywords. Those articles are full-text, published in 2010-2020. The result stated the average vaule of pain scalee was 6,24 before the treatment and it reduced into 2,07 after it, with the p-value 0,000. It proved the therapy has effectively reduced oain in patients with postoperative benign prostate hyperplasia. Thus, nurses suggested applying this therapy as an alternative to reduce the problem.Keywords: Benson’s relaxation, pain, postoperative benign prostate hyperplasia AbstrakBenigna Prostat Hyperplasia (BPH) adalah pembesaran progresif dari kelenjar prostat yang dapat diatasi dengan tindakan pembedahan.

The Association between Trichomonas Vaginalis Infection and The Risk of Benign Prostate Hyperplasia, Prostate Cancer, and Bladder Cancer in Patients: A Nationwide Population-Based Case-Control Study

Introduction: Trichomonas vaginalis infection is one of the most widespread sexually transmitted infections in the world. There are approximately 276 million cases worldwide. Most men remain undiagnosed and untreated because they are asymptomatic. The chronic inflammation induced by persistent infection may increase the risk of developing genitourinary cancers. In this study, we aimed to investigate the association between trichomoniasis and benign prostate hyperplasia (BPH), prostate cancer (PCa), and bladder cancer (BC) in Taiwan.Material and method: We designed a case-control study by using the database of the National Health Insurance program in Taiwan. We used the International Classification of Diseases, 9th Revision classifications to classify all the medical conditions in the case and control groups. All odds ratios (ORs) and 95% confidence intervals (CIs) were analyzed using multivariable logistic regression to adjust for all comorbidities and variables.Result: From 2000 to 2015, we enrolled a total of 62,544 individuals as the case group and 187,632 as the control group. Trichomoniasis exposure had a significant association with BPH and PCa (adjusted OR: BPH = 2.685, 95% CI = 1.233–4.286, P = 0.013; PCa = 5.801, 95% CI = 1.296–26.035, P = 0.016). The relative risk was much higher if patients had both trichomoniasis and depression (adjusted OR = 7.682, 95% CI = 5.730–9.451, P < 0.001).Conclusion: Men with trichomoniasis had a significantly higher risk of developing BPH and PCa than those without. Healthcare professionals should not only pay more attention to disease treatment, but also to public health education.
