Trends in Targeted Prostate Brachytherapy: from Multiparametric MRI to Nanomolecular Radiosensitizers
Nicolae et al.

Recent research into the biological nature of prostate cancer Canada has shown that large localized doses of radiation to the cancer offer excellent long- Full list of author information is available at the end of the term disease control. Brachytherapy, a form of localized radiation therapy, has been article shown to be one of the most effective methods for delivering high radiation doses to the cancer; however, recent evidence suggests that increasing the localized radiation dose without bound may cause unacceptable increases in long-term side effects. This review focuses on methods that have been proposed, or are already in clinical use, to safely escalate the dose of radiation within the prostate. The advent of multiparametric magnetic resonance imaging (mpMRI) to better identify and localize intraprostatic tumors, and nanomolecular radiosensitizers such as gold nanoparticles (GNPs), may be used synergistically to increase doses to cancerous tissue without the -

Prostate Biopsy in the Staging of Prostate Cancer

Prostate biopsies were initially indicated for the diagnosis of cancer, by the perineal approach under general anesthesia. Nowadays prostate biopsies are not only for diagnostic purposes but also to determine the prognosis, particularly before radical prostatectomy. They are performed in patients with elevated PSA levels, by the endorectal approach, sometimes under local anesthesia.(1±3) The gold standard is the sextant biopsy technique described by Hodge4,5, which is best to diagnose prostate cancer, particularly in case of T1c disease (patients with serum PSA elevation).6±13 Patients with a strong suspicion of prostate cancer from a negative series of biopsies can undergo a second series14;15 with transition zone biopsy16,17 or lateral biopsy.18,19 Karakiewicz et al 20 and Uzzo et al 21 proposed that the number of prostate biopsies should depend on prostate volume to improve the positivity rate. After the diagnosis of prostate cancer, initial therapy will depend on several prognostic factors. In the case of radical prostatectomy, the results of sextant biopsy provide a wealth of information.22,23 The aim of this report is to present the information given by prostate biopsy in the staging of prostate cancer. -
A Review of Rectal Toxicity Following Permanent Low Dose-Rate Prostate Brachytherapy and the Potential Value of Biodegradable Rectal Spacers
Prostate Cancer and Prostatic Disease (2015) 18, 96–103 © 2015 Macmillan Publishers Limited All rights reserved 1365-7852/15 www.nature.com/pcan REVIEW A review of rectal toxicity following permanent low dose-rate prostate brachytherapy and the potential value of biodegradable rectal spacers ME Schutzer1, PF Orio2, MC Biagioli3, DA Asher4, H Lomas1 and D Moghanaki1,5 Permanent radioactive seed implantation provides highly effective treatment for prostate cancer that typically includes multidisciplinary collaboration between urologists and radiation oncologists. Low dose-rate (LDR) prostate brachytherapy offers excellent tumor control rates and has equivalent rates of rectal toxicity when compared with external beam radiotherapy. Owing to its proximity to the anterior rectal wall, a small portion of the rectum is often exposed to high doses of ionizing radiation from this procedure. Although rare, some patients develop transfusion-dependent rectal bleeding, ulcers or fistulas. These complications occasionally require permanent colostomy and thus can significantly impact a patient’s quality of life. Aside from proper technique, a promising strategy has emerged that can help avoid these complications. By injecting biodegradable materials behind Denonviller’s fascia, brachytherpists can increase the distance between the rectum and the radioactive sources to significantly decrease the rectal dose. This review summarizes the progress in this area and its applicability for use in combination with permanent LDR brachytherapy.

Modern Pathology (2018) 31, S96–S109 S96 © 2018 USCAP, Inc All rights reserved 0893-3952/18 $32.00 Prostate cancer reporting and staging: needle biopsy and radical prostatectomy specimens David J Grignon Department of Pathology and Laboratory Medicine, Indiana University School of Medicine, IUH Pathology Laboratory, Indianapolis, IN, USA Prostatic adenocarcinoma remains the most common cancer affecting men. A substantial majority of patients have the diagnosis made on thin needle biopsies, most often in the absence of a palpable abnormality. Treatment choices ranging from surveillance to radical prostatectomy or radiation therapy are largely driven by the pathologic findings in the biopsy specimen. The first part of this review focuses on important morphologic parameters in needle biopsy specimens that are not covered in the accompanying articles. This includes tumor quantification as well as other parameters such a extraprostatic extension, seminal vesicle invasion, perineural invasion, and lymphovascular invasion. For those men who undergo radical prostatectomy, pathologic stage and other parameters are critical in prognostication and in determining the appropriateness of adjuvant therapy. Staging parameters, including extraprostatic extension, seminal vesicle invasion, and lymph node status are discussed here. Surgical margin status is also an important parameter and definitions and reporting of this feature are detailed. Throughout the article the current reporting guidelines published by the College of American Pathologists and the International Collaboration on Cancer Reporting are highlighted.

PPB is an outpatient procedure with short treatment time, rapid patient recovery, and demonstrated long-term efficacy. For men with low-risk disease, treatment efficacy is comparable to other primary treatment options [2-5]. -
