PURPOSE: To evaluate Focal therapy (FT) by means of high-intensity focussed ultrasound (HIFU) hemiablation in a prospective trial. MATERIALS AND METHODS: Prospective multicentre single arm study in patients with unilateral low/intermediate risk PC, treated from April 2013 through March 2016 in Germany (AUO study protocol AP 68/11). Unilateral PC was assessed by transrectal ultrasound (TRUS)-guided biopsy and multiparametric magnetic resonance imaging (mpMRI). Hemiablation was performed with the Ablatherm or Focal One device. Oncologic outcome was assessed by salvage-treatment rate, mpMRI and re-biopsy at 12 months. Functional outcome, quality of life (QOL), anxiety and depression by validated questionnaires at baseline and every three months. RESULTS: 51 of 54 recruited patients completed ≥ 12 month visits. Mean follow-up was 17.4 ± 4.5 months. Mean PSA dropped from 6.2±2.0 ng/ml to 2.9±1.9 ng/ml at 12 months (p<0.001). Biopsy at 12 months was positive for any and for clinically significant (cs)PC in 13/49 (26.5%) and 4/49 (8.2%) patients, respectively. Posttreatment mpMRI demonstrated limited sensitivity (25%) for csPC. 10 (19.6%) patients underwent salvage treatment. Potency was maintained in 21 of 30 preoperatively potent men. There was no increase in incontinence. QOL, anxiety and depression were not changed postoperatively. The study is limited by short follow-up and lack of a control arm. CONCLUSIONS: FT hemiablation is safe with little alterations of functional outcome. Oncologic outcome is acceptable on short term follow-up. Follow-up mpMRI performed poorly and should not replace repeat-biopsy. FT has no impact on post-treatment anxiety and depression.

Kidney international
In autosomal dominant polycystic kidney disease, total kidney volume and age can identify patients with progressive disease. Texture analysis of magnetic resonance imaging that computerizes and extracts differences in signals that we cannot sense visually is now demonstrated as a significant prognostic biomarker for the progression of renal decline in autosomal dominant polycystic kidney disease. Image analysis holds promise for providing a new dimension for the management of autosomal dominant polycystic kidney disease.

Purpose To correlate quantitative diffusion-weighted imaging (DWI) parameters derived from conventional monoexponential DWI, stretched exponential DWI, diffusion kurtosis imaging (DKI), and diffusion-tensor imaging (DTI) with quantitative histopathologic tumor tissue composition in prostate cancer in a preliminary hypothesis-generating study. Materials and Methods This retrospective institutional review board-approved study included 24 patients with prostate cancer (mean age, 63 years) who underwent magnetic resonance (MR) imaging, including high-b-value DWI and DTI at 3.0 T, before prostatectomy. The following parameters were calculated in index tumors and nontumoral peripheral zone (PZ): apparent diffusion coefficient (ADC) obtained with monoexponential fit (ADCME), ADC obtained with stretched exponential modeling (ADCSE), anomalous exponent (α) obtained at stretched exponential DWI, ADC obtained with DKI modeling (ADCDKI), kurtosis with DKI, ADC obtained with DTI (ADCDTI), and fractional anisotropy (FA) at DTI. Parameters in prostate cancer and PZ were compared by using paired Student t tests. Pearson correlations between tumor DWI and quantitative histologic parameters (nuclear, cytoplasmic, cellular, stromal, luminal fractions) were determined. Results All DWI parameters were significantly different between prostate cancer and PZ (P < .012). ADCME, ADCSE, and ADCDKI all showed significant negative correlation with cytoplasmic and cellular fractions (r = 0.546 to -0.435; P < .034) and positive correlation with stromal fractions (r = 0.619-0.669; P < .001). ADCDTI and FA showed correlation only with stromal fraction (r = 0.512 and -0.413, respectively; P < .045). α did not correlate with histologic parameters, whereas kurtosis showed significant correlations with histopathologic parameters (r = 0.487, 0.485, -0.422 for cytoplasmic, cellular, and stromal fractions, respectively; P < .040). Conclusion Advanced DWI methods showed significant correlations with histopathologic tissue composition in prostate cancer. These findings should be validated in a larger study.
