What to Expect When Active Surveillance Leads to Prostatectomy | Medpage Today: High-risk features in 39% of prostate specimens at surgery

Defining Intermediate-Risk Prostate Cancer Suitable for Active Surveillance - The Journal of Urology: Active surveillance (AS) for intermediate-risk prostate cancer (PCa) is controversial.
Many AS programs are limited to grade group (GG) 1 (Gleason 6) and PSA<10 ng/ml. However,
recent guidelines state that AS can be considered for limited GG2 (Gleason 3+4), despite
limited data on outcomes. Our objective was to compare prostatectomy outcomes between
subgroups of intermediate-risk versus low-risk PCa.

Worth a local treatment? – Analysis of modern radiotherapy concepts for oligometastatic prostate cancer | Radiation Oncology | Full Text: Prostate cancer (PCA) is the most-prevalent non-skin cancer in men worldwide. Nevertheless, the treatment of oligometastatic, especially lymph-node (ln) recurrent, PCA remains elusive. The aim of our study was to provide insights in radiotherapy (RT)-treatment of recurrent PCA exhibiting ln- or osseous (oss)-oligometastases. Between April 2012 and April 2017, 27 oligometastatic PCA patients (19 ln and 8 single oss) were treated with RT at our institution. The metastasis-free survival (MFS) was 24.8 m (22.0–36.0 m) and 25.4 m (23.9–28.1 m) for the ln- and oss-subgroup resulting in 1-year MFS of 75.4 and 100% and 2-year MFS of 58.7 and 83.3% for ln- and oss-metastatic patients, respectively. Of notice, none of the recurrences for ln-patients was in the RT-field, constituting a local control of 100%. Within the ln-group, pre-RT median-PSA was 2.6 ng/ml, median post-RT PSA was 0.3 ng/ml, which was significant (p = 0.003). Median biochemical-free survival (bfS) was 12.2 m. PCA that was initially confined to the prostate had a better bfS (p < 0.001) and MFS (p = 0.013). The oss-group had a median PSA of 4.9 ng/ml pre-treatment which dropped to a median value of 0.14 ng/ml (p = 0.004). To

Three-dimensional localization and targeting of prostate can... : Current Opinion in Urology: d follow-up. However, the accuracy of MRI to detect clinically significant disease is variable between different institutions. The role of quality control initiatives to increase the concordance between clinical-imaging–histopathological data and to improve accurate targeting of the suspicious lesions cannot be overemphasized. This article describes the approaches to correlate mpMRI findings with histopathology and the role of multidisciplinary teams for quality improvement and feedback interventions.
Recent findings
Validating the mpMRI and image-targeted fusion biopsy findings with prostatectomy specimen histopathology as the gold standard is essential for assessment of the concordance between clinical-imaging–histopathological data. Utilization of a MRI-derived patient-specific prostate mold enables a direct comparison between histopathological versus imaging characteristics of cancer foci in the same sectional plane of the specimen versus MRI. Furthermore, ‘reverse fusion’ technology provides the ability to audit the quality of targeting following fusion biopsy.
Summary
The development of a multidisciplinary team approach with group discussions, workflows to integrate and cor

MRI to guide biopsies or avoid biopsies? : Current Opinion in Urology: of care for men with increased suspicion for prostate cancer, MRI with or without targeted biopsy has been shown to reliably improve the detection of clinically significant disease following a prior negative biopsy. At the same time, there is a growing body of evidence to support the use of MRI for diagnostic purposes in biopsy-naive patients, as well for enrolling and monitoring men on active surveillance programs.
Summary
mpMRI is an evolving technology with great promise for altering our approach to prostate cancer diagnosis and surveillance. In conjunction with targeted biopsies, MRI offers greater specificity for the detection of clinically significant cancer and therefore may help to reduce overdetection of indolent disease while minimizing the risks and limitations of systematic biopsies.
