Background: A definition of the best strategy is necessary to optimize the follow-up of patients with previous negative transrectal guided ultrasound biopsy (TRUS-GB) and the persistence of raised prostate-specific antigen (PSA).The purpose of this study was to evaluate the prostate cancer (PCa) diagnostic rate of targeted transperineal ultrasound guided biopsy (TPUS-GB) with cognitive multiparametric magnetic resonance imaging (mpMRI) registration with concurrent systematic biopsy in patients with previous negative systematic TRUS-GB and persistently elevated PSA levels. Materials and methods: In this prospective study conducted at the University Infanta Sofia Hospital from April 2016 to November 2017, patients with one previous negative systematic TRUS-GB and persistently high PSA levels were referred for mpMRI prostate scans. All patients underwent systematic TPUS-GB and those patients with suspicious findings on mpMRI scans, Pirads 3 and 4-5, underwent a subsequent cognitive guidance mpMRI-TPUS-GB. Results: In total, 71 patients were included in this study. Suspicious findings on mpMRI scans prior to TPUS-GB were found in 50 patients (70.4%). 16 patients were diagnosed with prostate cancer (22.5%), of whom 14 (87.5%) had a mpMRI scan with Pirads 3 or Pirads 4-5. Patients with Pirads 3, 4 or 5 showed negative results in almost all cores taken by concurrent systematic TPUS-GB. Conclusions: Cognitive mpMRI-TPUS fusion biopsy is a useful tool to diagnose PCa in patients with previous negative prostate biopsy. The samples obtained from the suspicious areas in the mpMRI detect more cases of intermediate and high risk PCa compared to the samples obtained at random or from non-suspicious areas.

Introduction. One of the biggest problems in the diagnosis of prostate cancer (PCa), which distinguishes it from many other solid tumour conditions, is the difficulty of detecting the tumour using standard imaging techniques. The primary method of diagnosis of PCa, which allows timely treatment, is prostate biopsy. However, under certain clinical situations a saturation biopsy allows a more accurate prediction of the volume and degree of malignancy of the tumour, which can be used to plan the tactics of treatment.Materials and methods. 81 patients were examined, whose mean age was 63.5 ± 7.4. The average volume of the prostate was 59 ± 24.2 cm3 , while the average level of the prostate-specific antigen was 12.5 ± 8.9 ng/ml. All patients underwent at least one transrectal prostate biopsy. The average duration of the transperineal saturation biopsy of the prostate was 25.2 ± 7.4 minutes. The average number of biopsies was 25.Results and discussion. Based on the results of transperineal saturation biopsy, prostate cancer was detected in 34 patients (43.2 %). Adenocarcinoma was detected in all patients with confirmed malignant pathology. Gleason grading was 6 points in 22 (27.1 %) patients, 7 in 9 (9.9 %) and 8 in 4 (4.9 %). Aggressive tumour types (Gleason 7 and 8) corresponded to PIRADS 4 and 5. In PIRADS 2 and 3, 80 % and 50 %, respectively, manifested prostatic adenoma without malignant manifestation. Following radical prostatectomy, the results of a planned morphological conclusion were studied alongside biopsy data. It was determined that in 80.0 % (n = 12) of cases the tumour did not go beyond the prostate capsule and in only 20.0 % (n = 3) of cases was not confined to the prostate. The coincidence of diagnosis based on biopsy results and morphological conclusion was 86.7 %.Conclusion. The study showed that saturation transperineal biopsy is often a reference diagnostic method when, despite the presence of clinical suspicion of PCa, a standard biopsy, including targeted fusion biopsies, fails to provide sufficient information to confirm or exclude PCa. In such situations, the proposed technique provides an alternative approach, with a good frequency of detection of prostate cancer.

Objectives: To compare pain, systemic lidocaine toxicity and complications between periprostatic with intraprostatic local anaesthesia for transrectal prostate biopsy. Methods: This study was carried out in the Department of Urology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka Medical College (DMCH) and Comfort Nursing Home, Dhaka during the period of January 2009 to October 2009, For this purpose, a total number of 60 consecutive patients having increased prostate specific antigen (PSA >4.0ng/ml), abnormal DRE/transrectal ultrasound were admitted in the above mentioned hospitals were enrolled in this study for surgical management. Results: The age ranged from 50 to 90 years and the maximum number was found in the age group of 61-70 years in both groups. The mean(±SD) age was 68.5±7.5 years and 70.3±8.2 years in group I and group II respectively. The mean(±SD) PSA was 17.0±12.8ng/ ml with their PSA ranged from 5.9- 62.8ng/ml in group I and in group II was 17.2±17.3ng/ml with their PSA ranged from 4.6 – 55.1ng/ml, which was not significant (p>0.05) between two groups. Normal digital rectal was found 14(46.7%) and 16(53.3%) in group I and group II respectively. Carcinoma was found 13(43.3%) and 14(46.7%) in group I and group II respectively and rest of them were benign in group I and group II respectively. The mean(±SD) pain degree during biopsy was 2.6±1.1 and 2.0±1.2 in group I and group II respectively according to allocated pain score. Pain degree after 30 minutes of biopsy, most of the patients had no pain in both groups. Pain during anesthesia it was found that 4(13.3%) and 13(43.3%) of the patients had no pain in group I and group II respectively. The mean(±SD) pain degree during anesthesia was 2.7±1.2 and 2.1±1.2 in group I and group II respectively. Conclusion: It is a simple and safe method that is less painful and it should be considered in all patients undergoing transrectal ultrasound guided prostate biopsy. The decreased discomfort of this procedure may enable more core biopsies to be taken in patients at high risk for prostate cancer or in those with an enlarged prostate Bangladesh Journal of Urology, Vol. 15, No. 2, July 2012 p.33-39

Definition Of

The incidence of prostate cancer (PC) has been increasing in Asian countries, where it was previously low. Although the adoption of a Westernized lifestyle is a possible explanation, the incidence is statistically biased due to the increase in prostate-specific antigen (PSA) screening and the accuracy of national cancer registration systems. Studies on latent PC provide less biased information. This review included studies evaluating latent PC in several countries after excluding studies using random or single-section evaluations and those that did not mention section thickness. The findings showed that latent PC prevalence has been stable since 1950 in Western countries, but has increased over time in Asian countries. Latent PC in Asian men has increased in both prevalence and number of high-grade cases. Racial differences between Caucasian and Asian men may explain the tumor location of latent PC. In conclusion, the recent increase in latent PC in Asian men is consistent with an increase in clinical PC. Evidence suggests that this increase is caused not only by the increase in PSA screening, but also by the adoption of a more Westernized lifestyle. Autopsy findings suggest the need to reconsider the definition of clinically insignificant PC.

AbstractTo analyze the clinical characteristics of patients with negative biparametric magnetic resonance imaging (bpMRI) who didn’t need prostate biopsies (PBs). A total of 1,012 male patients who underwent PBs in the First Affiliated Hospital of Nanjing Medical University from March 2018 to November 2019, of 225 had prebiopsy negative bpMRI (defined as Prostate Imaging Reporting and Data System (PI-RADS 2.1) score less than 3). The detection efficiency of clinically significant prostate cancer (CSPCa) was assessed according to age, digital rectal examination (DRE), prostate volume (PV) on bpMRI, prostate-specific antigen (PSA) and PSA density (PSAD). The definition of CSPCa for Gleason score > 6. Univariate and multivariable logistic regression analysis were used to identify predictive factors of absent CSPCa on PBs. Moreover, absent CSPCa contained clinically insignificant prostate cancer (CIPCa) and benign result. The detection rates of present prostate cancer (PCa) and CSPCa were 27.11% and 16.44%, respectively. Patients who were diagnosed as CSPCa had an older age (P < 0.001), suspicious DRE (P < 0.001), a smaller PV (P < 0.001), higher PSA value (P = 0.008) and higher PSAD (P < 0.001) compared to the CIPCa group and benign result group. PSAD < 0.15 ng/ml/cm3 (P = 0.004) and suspicious DRE (P < 0.001) were independent predictors of absent CSPCa on BPs. The negative forecast value of bpMRI for BP detection of CSPCa increased with decreasing PSAD, mainly in patients with naive PB (P < 0.001) but not in prior negative PB patients. 25.33% of the men had the combination of negative bpMRI, PSAD < 0.15 ng/ml/cm3 and PB naive, and none had CSPCa on repeat PBs. The incidence of PB was determined, CSPCa was 1.59%, 0% and 16.67% in patients with negative bpMRI and PSAD < 0.15 ng/ml/cm3, patients with negative bpMRI, PSAD < 0.15 ng/ml/cm3 and biopsy naive and patients with negative bpMRI, PSAD < 0.15 ng/ml/cm3 and prior negative PB, separately. We found that a part of patients with negative bpMRI, a younger age, no suspicious DRE and PSAD < 0.15 ng/ml/cm3 may securely avoid PBs. Conversely PB should be considered in patients regardless of negative bpMRI, especially who with a greater age, obviously suspicious DRE, significantly increased PSA value, a significantly small PV on MRI and PSAD > 0.15 ng/ml/cm3.

ABSTRACT Objective: to develop a predictive model to estimate the probability of prostate cancer prior to biopsy. Methods: from September 2009 to January 2014, 445 men underwent prostate biopsy in a radiology service. We excluded from the study patients with diseases that could compromise the data analysis, who had undergone prostatic resection or used 5-alpha-reductase inhibitors. Thus, we selected 412 patients. Variables included in the model were age, prostate specific antigen (PSA), digital rectal examination, prostate volume and abnormal sonographic findings. We constructed Receiver Operating Characteristic (ROC) curves and calculated the areas under the curve, as well as the model's Positive Predictive Value (PPV) . Results: of the 412 men, 155 (37.62%) had prostate cancer (PC). The mean age was 63.8 years and the median PSA was 7.22ng/ml. In addition, 21.6% and 20.6% of patients had abnormalities on digital rectal examination and image suggestive of cancer by ultrasound, respectively. The median prostate volume and PSA density were 45.15cm3 and 0.15ng/ml/cm3, respectively. Univariate and multivariate analyses showed that only five studied risk factors are predictors of PC in the study (p<0.05). The PSA density was excluded from the model (p=0.314). The area under the ROC curve for PC prediction was 0.86. The PPV was 48.08% for 95%sensitivity and 52.37% for 90% sensitivity. Conclusion: the results indicate that clinical, laboratory and ultrasound data, besides easily obtained, can better stratify the risk of patients undergoing prostate biopsy.

Introduction Prostate cancer is one of the most common cancer in elderly male. Suspicion of prostate cancer is based on increased Prostate Specific Antigen (PSA) level and abnormal digital rectal examination (DRE) findings. Transrectal ultrasonography (TRUS) can detect and localize hypoechoic lesions in prostate which are considered as suspicious for malignancy. TRUS can also guide for prostate biopsy, which is the gold standard for diagnosis of prostate cancer. The study was aimed to find out TRUS findings in suspected prostate cancer patients and correlate these findings with histopathological findings. MethodsProspective study was done in 66 males of age >40 years, sent for prostate biopsy in suspicion for prostate cancer (PSA >4 ng/ml, and/or abnormal DRE findings). Prostate was evaluated with TRUS and subsequently underwent TRUS guided six core biopsy of prostate. Total 396 cores of biopsy were taken. Histopathology reports were collected and correlated with the TRUS findings. ResultsTwenty three patients were positive for prostate cancer and 14 of them showed hypoechoic lesions in TRUS. Total 81 suspicious hypoechoic lesions were seen in prostate of all the patients and among them 42 lesions matched with histopathology report for cancer. Cancerous focus detection rate of TRUS was 51.85%. ConclusionTRUS is a supplementary tool in diagnosis of prostate cancer, however when used alone it has less sensitivity for detection of prostate cancer.
