BackgroundHigh-grade urothelial carcinomas (UCs) often show foci of variant differentiation. There is limited information in the literature about the response of these variant urothelial tumors to immunotherapy with bacillus Calmette–Guerin (BCG). We compared the response, to treatment with BCG, of UC containing glandular, squamous, nested, and micropapillary types of differentiation to response of conventional non-muscle invasive high-grade UC.MethodsA total of 100 patients were diagnosed with variant histology urothelial cancer between June 1995 and December 2013. Forty-one patients with Ta or T1, confirmed by second look biopsies, received immunotherapy with BCG. Fourteen patients in this group were diagnosed with micropapillary differentiation, 13 patients with squamous differentiation, 9 patients with glandular differentiation, and 7 patients with nested variants. The control group included 140 patients with conventional high-grade UC. Both groups have been treated and followed similarly.FindingsPatients with variant tumors had similar clinical features to patients with conventional disease, including age, male to female ratio, stage, the presence of Tis, and median follow-up. Patients with variant tumors had a significantly worse prognosis compared to patients with conventional high-grade UC, including 5-year recurrence-free survival (63.5 Vs. 71.5%, p = 0.05), 5-year progression (≥T2)-free survival (60 Vs. 82.5%, p = 0.002), 5-year disease-specific survival (73 Vs. 92.5%, p = 0.0004), and overall survival (66 Vs. 89.5%, 0.05).InterpretationA patient with variant bladder cancer treated with intravesical immunotherapy has a 27% chance of dying from this disease within 5 years compared to 7.5% chance for a patient with conventional high-grade UC.

Pregnancies complicated by placenta accreta are at increased risk for perinatal adverse outcome. We speculate that these findings may arise from pathological implantation of the placenta, resulting in interference with normal fetal growth.

Multiparametric magnetic resonance imaging is able to detect high-volume significant prostate cancer following focal therapy. Prostate biopsies are still required in the follow-up of focal therapy as (low-volume) significant prostate cancer is being missed by multiparametric magnetic resonance imaging.

Several studies suggest decreased fertility potential in patients with a history of testicular torsion. However, in the current study in couples in which the male had a history of testicular torsion the pregnancy rate and the interval to pregnancy were within the accepted range of the general population.

PurposeThe design, conduct and completion of randomized trials for curative prostate cancer (PCa) treatments are challenging. To evaluate the effect of robot-assisted radical prostatectomy (RARP) versus focal irreversible electroporation (IRE) on patient-reported quality of life (QoL) and early oncological control using propensity-scored matching.MethodsPatients with T1c–cT2b significant PCa (high-volume ISUP 1 or any 2/3) who received unifocal IRE were pair-matched to patients who received nerve-sparing RARP. Patient-reported outcomes were prospectively assessed using the Expanded Prostate Cancer Index Composite (EPIC), AUA symptom score and Short Form of Health Survey (SF-12) physical and mental components. Oncological failure was defined as biochemical recurrence (RARP) or positive follow-up biopsies (IRE). Generalized mixed-effect models were used to compare IRE and RARP.Results50 IRE patients were matched to 50 RARP patients by propensity score. IRE was significantly superior to RARP in preserving pad-free continence (UC) and erections sufficient for intercourse (ESI). The absolute differences were 44, 21, 13, 14% for UC and 32, 46, 27, 22% for ESI at 1.5, 3, 6, and 12 months, respectively. The EPIC summary scores showed no statistically significant differences. Urinary symptoms were reduced for IRE and RARP patients at 12 months, although IRE patient initially had more complaints. IRE patients experienced more early oncological failure than RARP patients.ConclusionsThese data demonstrated the superior preservation of UC and ESI with IRE compared to RARP up to 12 months after treatment. Long-term oncological data are warranted to provide ultimate proof for or against focal therapy.Electronic supplementary materialThe online version of this article (10.1007/s00345-018-2281-z) contains supplementary material, which is available to authorized users.

share equal senior contribution. ObjectiveTo evaluate the clinical presentation and treatment outcomes of prostate cancer (PCa) in 432 consecutive patients aged < 50 years in the prostate-specific antigen (PSA) era. MethodsRetrospective analysis was performed on all patients with PCa (14 570) from the years 1994 to 2017. A total of 432 consecutive patients aged < 50 years were identified. The patients were stratified by D'Amico risk groups, and their clinical presentation and treatment outcomes were analysed. The rates of biochemical recurrence after surgery were compared with the D'Amico prediction model as well as with older propensity-score-matched patients. The surgical pathology results in patients undergoing active surveillance (AS) were compared with those of low-risk patients who underwent immediate surgery. ResultsA total of 44%, 42% and 13% of patients harboured low-risk, intermediate-risk and high-risk PCa, respectively. Their median age was 47 years and a positive family history of PCa was reported in 39.1%. Clinical stage was T1 in 65.5% and T2 in 30.0% of patients, and 2.0% of patients had metastatic disease at presentation. Radical prostatectomy (RP) was performed in 78.4% of patients (n = 339) and the biochemical recurrence rates were 7.8% (low-risk), 15.3% (intermediate-risk) and 23.3% (high-risk) at 5 years postsurgery. These rates were lower than expected according to the D'Amico prediction model or when compared with older matched patients. A total of 74 patients with low-risk PCa underwent AS and only 17.6% (n = 13) required radical treatment after a median follow-up of 46 months. The surgical pathology results in patients undergoing ASdid not differ significantly from patients with low-risk PCa who underwent immediate surgery (positive surgical margins [P = 0.145], tumour volume [P = 0.257] or seminal vesicle involvement [P = 0.100]). Of the present cohort, only 0.4% died from PCa during a median follow-up of 65 months. ConclusionsThe clinical presentation and prognosis of young patients has changed dramatically during the PSA era. Patients nowadays present with lower-risk disease that can be treated adequately, with reassuring biochemical recurrence rates at 5 years postsurgery. AS appears to be safe in patients with low-risk.

This pilot study shows that urinary cell H19 is a highly sensitive test for UC and pending verification could transform patient management.

IntroductionThree percent of all new diagnosed prostate cancer (PC) patients are under the age of 50. Multiparametric MRI (mpMRI) is considered as increasingly powerful tool for decision-making in diagnosis of PC and in some active surveillance protocols. Since prostate architecture changes with age, we evaluated the sensitivity of mpMRI to detect clinically significant PC in patients under the age of 50 compared to pair-matched older patients.MethodsData from a prospective collected and ethics approved database were retrospectively analyzed. We reviewed 1,395 records of PC patients from the years 2012–2017, identifying those under the age of 50 who had radical prostatectomy as primary treatment, a pre-operative mpMRI, a full clinical data set and who had clinically significant cancer (N=51). Tumor size and International Society of Urological Pathology (ISUP) score pair-matching was performed for patients older than 55 years. Clinically significant cancer was defined as ISUP >2 or ISUP 2 with >5% Gleason 4. The sensitivity to detect clinically significant cancer with mpMRI was calculated using pre-operative Prostate Imaging Reporting and Data System (PI-RADS) score and whole-gland final pathology.ResultsThe median patient age in the young and older groups was 47 and 62, respectively. Both cohorts matched significantly regarding tumor volume (P =0.91) and ISUP score (P =1.0). The median PI-RADS score for the young group was 3, and 4 for the older group. The sensitivity for mpMRI, for PI-RADS 3,4 and 5 was 80.3% (95% CI 66.8%–90.1%) in the young group and 84.3% in the older group (95% CI 71.4%–92.9%), demonstrating no statistically significant difference (P=0.603). Sensitivity of mpMRI for PI-RADS 4,5 was 49.0% (95% CI 34.7%–63.4%) for the young group and 72.5% (95% CI 58.2%–84.1%) for the older group, which differ significantly (P=0.014).ConclusionsmpMRI may have a reduced sensitivity for detecting clinically significant PC in patients under the age of 50 for PI-RADS score 4,5 lesions. Many significant PC lesions were reported as PI-RADS 3 under the age of 50. We recommend that increased significance is placed on PI-RADS 3 lesions found in patients under the age of 50.
