PURPOSE: Multiparametric MRI (mpMRI) has a potential role for the identification of aggressive cancer that can be targeted for biopsy. We report the incidence and severity of discordant information between the pathology found on the transrectal ultrasound (TRUS)-guided biopsy and the mpMRI findings in patients with favorable or intermediate-risk prostate cancer referred for brachytherapy. METHODS AND MATERIALS: From March 2014 to September 2015, 10/44 consecutive patients with low- or intermediate-risk prostate cancer referred for brachytherapy presented an aggressive lesion on mpMRI and underwent an MRI-TRUS fusion-guided transperineal biopsy of the index lesion...

We report a case of nonischemic priapism following brachytherapy. A 63-year-old man presented 22 days after brachytherapy for prostate cancer. He suffered painless sustained incomplete erection for a few days. The patient was diagnosed with nonischemic priapism by cavernosal blood gas analysis. Right internal pudendal arteriography showed blood pooling in the cavernosum caused by arteriovenous fistula. Selective arterial embolization with gelatin sponge particles was performed and detumescence achieved. To our knowledge,this is the first case of high flow priapism caused by brachytherapy for prostate cancer...

PURPOSE: To determine the dosimetric feasibility of dose-escalated MRI-guided high-dose-rate brachytherapy (HDR-BT) focal monotherapy for prostate cancer (PCa). METHODS: In all patients, GTV was defined with mpMRI, and deformably registered onto post-catheter insertion planning MRI. PTV included the GTV plus 9mm craniocaudal and 5mm in every other direction. In discovery-cohort, plans were obtained for each PTV independently aiming to deliver ⩾16.5Gy/fraction (two fraction schedule) while respecting predefined organs-at-risk (OAR) constraints or halted when achieved equivalent single-dose plan (24Gy)...

PURPOSE: Prostate brachytherapy is an important treatment technique for patients with localized prostate cancer. An inflatable rectal ultrasound probe cover is frequently utilized during the procedure to adjust for unfavorable prostate position relative to the implant grid. However, the inflated cover causes prostate deformation, which is not accounted for during dosimetric planning. Most of the therapeutic dose is delivered after the procedure when the prostate and surrounding organs-at-risk are less deformed...

Essi Kovalainen, Markku H Vaarala
The aim of this study was to evaluate risk factors for biochemical failure (BF) following permanent prostate seed (125)I brachytherapy for prostate cancer. The study reviewed the medical records of 607 patients with biopsy-proven prostate adenocarcinoma who were treated at Oulu University Hospital between 2001 and 2014. Clinical characteristics at diagnosis, treatment-related data and follow-up data were collected to identify potential risk factors for BF, which was defined using the Phoenix criteria [prostate-specific antigen (PSA) increase >2 µg/l from the PSA nadir concentration, which defined as the lowest PSA concentration observed after BT]...

BACKGROUND: The risk stratification currently applied prior to curative treatment for localized prostate cancer (PC) does not take into account comorbidity or age. Therefore, we investigated the impact of comorbidity on overall survival (OS) in PC patients treated with external beam radiotherapy (EBRT) and high-dose rate (HDR) brachytherapy boost. MATERIAL AND METHODS: At a single center, 611 consecutive patients diagnosed with localized PC from 1998 to 2004 underwent definitive EBRT (50 Gy) and HDR brachytherapy boosts (2 × 10 Gy) combined with neoadjuvant total androgen blockade...

We report here lessons learned from an autopsy case involving radioactive materials. We performed an autopsy of an unidentified mummified man with no available medical history whom from imaging findings we suspected had received radioactive seed implants for prostate brachytherapy. We returned the excised prostate and seeds to the body. A few days later, the body was identified by DNA matching and cremated. According to the man's medical record, he had undergone iodine-125 seeds implantation for prostate cancer 11 months earlier...

BACKGROUND: Several systems for MRI/TRUS fusion-guided biopsy of the prostate are commercially available. Many studies have shown superiority of fusion systems for tumor detection and diagnostic quality compared to random biopsy. The benefit of fusion systems in focal therapy of prostate cancer (PC) is less clear. OBJECTIVES: Critical considerations of fusion systems for planning and monitoring of focal therapy of PC were investigated. MATERIALS AND METHODS: A systematic literature review of available fusion systems for the period 2013-5/2016 was performed...

Radiation therapy represents an alternative treatment to radical prostatectomy in the management of clinically localized prostate cancer. Radiation-induced second neoplasms are defined by a latency period of at least 5 years, location within the field of radiation therapy, and a histology which differs from the primary tumor. Based on the data in the literature, there is a consistently increased risk of bladder cancer (HR: 1.67, 95% CI 1.55-1.80), rectal cancer (HR: 1.79, 95% CI 1.34-2.38), and colorectal cancer (HR: 1...

BACKGROUND: The treatment options for high-risk prostate cancer are either radical prostatectomy or radiotherapy/brachytherapy depending on the patients' prognosis. In older men with multiple comorbidities, radiotherapy with androgen deprivation therapy is an attractive option. Common side effects of androgen deprivation therapy include hot flushes, tiredness, increased risk of fractures, increased risk of metabolic disorders, coronary heart disease, and psychological effects. This case highlights the potential side effect of lipodystrophy secondary to leuprolide acetate injections...
