Radical perineal prostatectomy
2004
Historically, perineal prostatectomy was the primary type of surgery for prostate cancer, performed for the first time by Billroth in 1867 mostly without visual control. However, Hugh Hampton Young received credit for the first perineal prostatectomy after reporting in 1905 his experience with a mostly visually controlled operation and new special instruments [1]. Different perineal routes of access to the prostate have been described, but the most commonly used route is Young’s suprasphincteric approach ventral to the external and internal sphincter ani. It was the mainstay of surgical treatment until by the mid of last century pelvic lymph node dissection became part of the procedure. Rad…
Single-institution experience with primary tumours of the male urethra
2007
OBJECTIVE To assess primary tumours of the urethra in males. PATIENTS AND METHODS We retrospectively reviewed our database from 1986 to 2006 for primary tumours of the male urethra; nine patients with primary tumours of the urethra were analysed and follow-up information was obtained. RESULTS Three patients had tumours of the prostatic urethra, two of which had proliferating focal inflammation and one a low-grade, superficial urothelial cancer. All patients were treated successfully with transurethral resection. Six patients had carcinoma of the bulbar or penile urethra, including two with previous local percutaneous radiotherapy for prostate cancer. All had primary surgical excision that w…
Focal Therapy for Prostate Cancer: Complications and Their Treatment
2021
Focal therapy is a modern alternative to selectively treat a specific part of the prostate harboring clinically significant disease while preserving the rest of the gland. The aim of this therapeutic approach is to retain the oncological benefit of active treatment and to minimize the side-effects of common radical treatments. The oncological effectiveness of focal therapy is yet to be proven in long-term robust trials. In contrast, the toxicity profile is well-established in randomized controlled trials and multiple robust prospective cohort studies. This narrative review summarizes the relevant evidence on complications and their management after focal therapy. When compared to whole glan…
Use of multiparametric magnetic resonance imaging and fusion-guided biopsies to properly select and follow African-American men on active surveillance
2019
OBJECTIVES To determine the rate of Gleason Grade Group (GGG) upgrading in African-American (AA) men with a prior diagnosis of low-grade prostate cancer (GGG 1 or GGG 2) on 12-core systematic biopsy (SB) after multiparametric magnetic resonance imaging (mpMRI) and fusion biopsy (FB); and whether AA men who continued active surveillance (AS) after mpMRI and FB fared differently than a predominantly Caucasian (non-AA) population. PATIENTS AND METHODS A database of men who had undergone mpMRI and FB was queried to determine rates of upgrading by FB amongst men deemed to be AS candidates based on SB prior to referral. After FB, Kaplan-Meier curves were generated for AA men and non-AA men who th…
The percentage of free prostate-specific antigen does not predict extracapsular disease in patients with clinically localized prostate cancer before …
2001
Objective To determine whether the percentage of free/total prostate-specific antigen (f/tPSA) can predict the pathological features in patients with clinically localized prostate cancer before radical prostatectomy. Patients and methods Univariate and multivariate logistic regression was used to analyse data from 171 untreated patients who underwent radical prostatectomy. Variables included the total PSA (tPSA), fPSA, f/tPSA, biopsy Gleason score, clinical stage and patient age. Results In 115 patients with pathologically organ-confined tumours ( pT2N0) the mean (sd) tPSA value was 6.9 (5.6) ng/mL; in 56 patients with extracapsular disease ( pT3pN0/N+) it was 10.2 (7.6) ng/mL; the respecti…
Zonal Segmentation of Prostate T2W-MRI using Atrous Convolutional Neural Network
2019
The number of prostate cancer cases is steadily increasing especially with rising number of ageing population. It is reported that 5-year relative survival rate for man with stage 1 prostate cancer is almost 99% hence, early detection will significantly improve treatment planning and increase survival rate. Magnetic resonance imaging (MRI) technique is a common imaging modality for diagnosis of prostate cancer. MRI provide good visualization of soft tissue and enable better lesion detection and staging of prostate cancer. The main challenge of prostate whole gland segmentation is due to blurry boundary of central gland (CG) and peripheral zone (PZ) which lead to differential diagnosis. Sinc…
Dental implants in patients treated with oral bisphosphonates. A bibliographic review
2010
Bisphosphonates inhibit bone resorption and are used to treat a range of pathologies, including Paget disease, osteoporosis, multiple myeloma and metastases associated with breast or prostate cancer. At present, there is no effective treatment for bisphosphonate induced osteonecrosis, so prevention is extremely important. Since quality of life deteriorates for those suffering osteonecrosis, maximum precautions should be taken with patients at risk, and especially whenever oral surgery, including dental implant placement, is contemplated. Dentists and oral or maxillofacial surgeons must keep up to date with the latest approaches to prevention, particularly when treating patients who are pres…

Inverse Comorbidity: The Power of Paradox in the Advancement of Science
2013
Abstract: Research on comorbidity and multimorbidity is finally receiving the attention it deserves, particularly considering the magnitude and impact they have on health and the delivery of healthcare [1,2]. Numerous studies have demonstrated that individuals with Down’s syndrome, Parkinson’s disease, schizophrenia, diabetes, anorexia nervosa, Alzheimer’s disease, allergy related diseases, multiple sclerosis or Huntington’s disease (among other health problems) are protected against many forms of cancer, including solid tumors, smoking-related tumors and prostate cancer. This apparent anti-cancer effect, which we have termed inverse cancer comorbidity, has been obse…
Clinical and biochemical markers of visceral adipose tissue activity: Body mass index, visceral adiposity index, leptin, adiponectin, and matrix meta…
2018
Context: The correlation between aggressive prostate cancer and obesity mainly based on body mass index (BMI) and pathology after surgery remains controversial. Aims: The aim of the study was to correlate BMI, visceral adiposity index (VAI), and the plasmatic levels of leptin, adiponectin, and matrix metalloproteinase-3 (MMP-3), and biomarkers of adipose tissue function, with the detection of Gleason patterns 4 and 5 at biopsy. Subjects and Methods: Consecutive patients with prostate cancer at 12-core transrectal biopsy were enrolled. BMI, waist circumference (WC), blood samples to evaluate the plasmatic levels of triglycerides (TG) and high-density lipoproteins (HDL), adiponectin, leptin, …
