    The over-all aim of the present study was to compare the results of treatment with curative intent, with conservative treatment in men with prostate cancer (PCa) without distant metastases. In a population-based cohort in Sweden, the predictive value of prostate-specific antigen (PSA) was evaluated and the relative survival of men considered plausible candidates for treatment with curative intent was investigated. We also evaluated the association between curative treatment and cause-specific mortality, and over-all as well as relative survival in men diagnosed with PCa with a serum PSA level between 20 and 100 ng/ml. Due to the uncertainly of transrectal ultrasound-guided biopsy in the diagnosis of PCa, we created a model for prostate imaging  to increase the safety of guided Core Needle Biopsy (CNB) in men with suspect PCa, thereby improving staging.  Material and methods. The cohorts in the first three studies were prospectively included in a population-based register (the National Prostate Cancer Register). Study IV was a clinical study on patients included between 2010 and 2011. Results. Regardless of Gleason Score, a positive relationship between survival and serum PSA level categories in patients with a PSA level> 4 ng/ml was found, but a paradoxical inverse relationship was observed in men with a PSA level < 4 ng/ml. Men with a well-differentiated tumour had a 5-year relative survival exceeding 100% regardless of treatment. The survival rate for moderately and poorly differentiated tumours was poor for men managed conservatively. The 10-year cause-specific mortality for patients with PSA 20-50 ng/ml was 36% for patients treated without and 13% for patients treated with curative intent. For patients with a PSA 50-100 ng/ml the 10-year cause-specific mortality was 55% for conservative and 20% for patients treated with curative intent. PCa detection by CNB, magnetic resonance imaging (MR) with ADC (Apparent diffusion coefficient), magnetic resonance spectroscopic imaging (MRSI) and Positron Emission Tomography (PET/CT) ¹¹C Acetate imaging applied to 10 sections of the prostate demonstrated clear conformity between MRI ADC mapping and postoperative findings, showing high specificity (87%) and sensitivity (95%). Conclusion. The inverse relationship between relative survival and PSA at levels below 4 ng/ml should be considered when choosing a PSA cut-off level. Outcome differs little between conservative management and treatment with curative intent in men with localised well- to moderately differentiated tumours over a 10-yr period. For men with poorly differentiated tumours, on the other hand, choice of treatment is crucial for outcome. Treatment with curative intent is beneficial in the group of men with prostate cancer and PSA levels between 20 and 100 ng/ml without distant metastases. A combination of MRI , diffusion ADC and MRSI may provide an improved model for imaging of the prostate for targeted biopsy

    Background: There is insufficient information regarding the benefit of treatment with curative intent for men with localised poorly differentiated prostate cancer (PCa). Objective: To evaluate relative survival in men with potentially curable PCa in relation to Gleason score (GS) and treatment as practiced in the community at large. Design, setting, and participants: A population-based study including all men with localised PCa registered in Sweden's National Prostate Cancer Register. Interventions: Hormonal therapy, watchful waiting, and treatment with curative intent. Measurements: The ratio of observed deaths to expected deaths, determined from survival in the general male population of the same age, was assessed using Poisson regression analysis, with GS and treatment as covariates. Interaction between GS and treatment was tested in a multivariate Cox proportional hazard analysis. Results and limitations: A total of 31 903 men with potentially curable tumour (T1-T3, N0/NX, M0/MX, age < 75 yr, and prostate-specific antigen [PSA] < 20 ng/ml) were identified. GS was recorded for 28 454 of these men. Some 19 606 men (60.8%) were treated with curative intent, and 12 645 men (39.2%) were given either hormonal treatment or expectant management. The ratios between observed and expected survival gradually increased for men with GS 10, with GS to 3.3 for men treated conservatively and to 1.4 for men treated with curative intent. There was a significant interaction between GS and treatment, with a relatively greater benefit from treatment with curative intent for men with high-grade tumours. The results have to be interpreted with some caution, as there was no randomisation between the treatment groups. Conclusions: Survival for men with well-differentiated tumours is close to that of the general population, regardless of treatment, but the outcome is dismal for men with poorly differentiated tumours, whichever treatment is applied. Nevertheless, men with poorly differentiated tumours benefit more from curative treatment than do men with well-differentiated tumours. (c) 2009 European Association of Urology.

    P-score in preoperative biopsies accurately predicts P-score in final pathology at radical prostatectomy in patients with localized prostate cancer

    BACKGROUND: Prostate cancer (PCa) is a highly heterogeneous, multifocal disease, and identification of clinically significant lesions is challenging, which complicates the choice of adequate treatment. The Prostatype® score (P-score) is intended to guide treatment decisions for newly diagnosed PCa patients based on a three-gene signature (IGFBP3, F3, and VGLL3) and clinicopathological information obtained at diagnosis. This study evaluated association of the P-score measured in preoperative magnetic resonance imaging/transrectal ultrasound fusion-guided core needle biopsies (CNBs) and the P-score measured in radical prostatectomy (RP) specimens of PCa patients. We also evaluated the P-score association with the pathology of RP specimens. Furthermore, concordance of the P-score in paired CNB and RP specimens, as well as in index versus concomitant nonindex tumor foci from the same RP was investigated. METHODS: The study included 100 patients with localized PCa. All patients were diagnosed by CNB and underwent RP between 2015 and 2018. Gene expression was assessed with the Prostatype® real-time quantitative polymerase chain reaction kit and the P-score was calculated. Patients were categorized into three P-score risk groups according to previously defined cutoffs. RESULTS: For 71 patients, sufficient CNB tumor material was available for comparison with the RP specimens. The CNB-based P-score was associated with the pathological T-stage in RP specimens (p = 0.02). Moreover, the CNB-based P-score groups were in substantial agreement with the RP-based P-score groups (weighted κ score: 0.76 [95% confidence interval, 95% CI: 0.60-0.92]; Spearman's rank correlation coefficient r = 0.83 [95% CI: 0.74-0.89]; p &lt; 0.0001). Similarly, the P-score groups based on paired index tumor and concomitant nonindex tumor foci (n = 64) were also in substantial agreement (weighted κ score: 0.74 [95% CI: 0.57-0.91]; r = 0.83 [95% CI: 0.73-0.89], p &lt; 0.0001). CONCLUSIONS: Our findings suggest that the P-score based on preoperative CNB accurately reflects the pathology of the whole tumor, highlighting its value as a decision support tool for newly diagnosed PCa patients

    Prostate biopsy sampling causes hematogenous dissemination of epithelial cellular material

    The extent of epithelial cellular material (ECM) occurring in venous blood samples after diagnostic core needle biopsy (CNB) was studied in 23 patients with CNB diagnosed prostate cancer without provable metastases and 15 patients without cancer. The data show a significant increase of ECM in the peripheral blood sampled 20 seconds or 30 minutes after the last of 10 CNB procedures compared to the number of ECM detectable in the blood samples taken before the performance of CNB. The data indicate that diagnostic CNB of prostate cancer causes an extensive tissue trauma with a potential risk of cancer cell dissemination

    Bi-parametric MRI/TRUS fusion targeted repeat biopsy after systematic 10-12 core TRUS-guided biopsy reveals more significant prostate cancer especially in anteriorly located tumors

    Background: MRI and fusion guided biopsy have an increased role in the diagnosis of prostate cancer. Purpose: To demonstrate the possible advantages with Bi-parametric MRI fusion-guided repeat biopsy over systematic 10-12-core biopsy for the diagnosis of prostate cancer. Material and Methods: Four hundred and twenty-three consecutive men, with previous systematic 10-12-core TRUS-guided biopsy, and with suspicion of, or diagnosis of, low-risk prostate cancer underwent fusion-guided prostate biopsy between February 2015 and February 2017. The material was retrospectively assessed. In 220 cases no previous cancer was diagnosed, and in 203 cases confirmatory fusion guided biopsy was performed prior to active monitoring. MRI was classified according to PI-RADS. Systematic biopsy was compared to fusion guided biopsy for the detection of cancer, and PI-RADS was compared to the Gleason score. Results: Fusion guided biopsy detected significantly more cancers than systematic (p &lt; .001). Gleason scores were higher in the fusion biopsy group (p &lt; .001). Anterior tumors were present in 54% of patients. Fusion biopsy from these lesions showed cancer in 53% with previously negative biopsy in systematic biopsies and 66% of them were upgraded from low risk to intermediate or high-risk cancers. Conclusion: These results show superior detection rate and grading of bi-parametric MRI/TRUS fusion targeted repeat biopsy over systematic 10-12 core biopsies. Fusion guided biopsy detects more significant cancers despite using fewer cores. The risk group was changed for many patients initially selected for active surveillance due to upgrading of tumors. Bi-parametric MRI shows promising results in detecting anterior tumors in patients with suspected prostate cancer

    Changes of arterial pressure following relief of obstruction in adults with hydronephrosis

    No full text
    Background: As much as 20% of all cases of hypertension are associated with kidney malfunctions. We have previously demonstrated in animals and in pediatric patients that hydronephrosis causes hypertension, which was attenuated by surgical relief of the ureteropelvic junction (UPJ) obstruction. This retrospective cohort study aimed to investigate: (1) the proposed link between hydronephrosis, due to UPJ obstruction, and elevated arterial pressure in adults; and (2) if elevated blood pressure in patients with hydronephrosis might be another indication for surgery. Materials and methods: Medical records of 212 patients undergoing surgical management of hydronephrosis, due to UPJ obstruction, between 2000 and 2016 were assessed. After excluding patients with confounding conditions and treatments, paired arterial pressures (i.e. before/after surgery) were compared in 49 patients (35 years old; 95% CI 29–39). Split renal function was evaluated by using mercaptoacetyltriglycine (MAG3) renography before surgical management of the hydronephrotic kidney. Results: Systolic (−11 mmHg; 95% CI 6–15 mmHg), diastolic (−8 mmHg; 95% CI 4–11 mmHg), and mean arterial (-9 mmHg; 95% CI 6–12) pressures were significantly reduced after relief of the obstruction (p &lt; 0.001). Split renal function of the hydronephrotic kidney was 39% (95% CI 37–41). No correlations were found between MAG3 and blood pressure level before surgery or between MAG3 and the reduction of blood pressure after surgical management of the UPJ obstruction. Conclusions: In adults with hydronephrosis, blood pressure was reduced following relief of the obstruction. Our findings suggest that elevated arterial pressure should be taken into account as an indication to surgically correct hydronephrosis
