Item Open Access Contemporary radical prostatectomy.(Prostate Cancer, 2011) Fu, Qiang; Moul, Judd W; Sun, LeonPurpose. Patients diagnosed with clinically localized prostate cancer have more surgical treatment options than in the past. This paper focuses on the procedures' oncological or functional outcomes and perioperative morbidities of radical retropubic prostatectomy, radical perineal prostatectomy, and robotic-assisted laparoscopic radical prostatectomy. Materials and Methods. A MEDLINE/PubMed search of the literature on radical prostatectomy and other new management options was performed. Results. Compared to the open procedures, robotic-assisted radical prostatectomy has no confirmed significant difference in most literatures besides less blood loss and blood transfusion. Nerve sparing is a safe means of preserving potency on well-selected patients undergoing radical prostatectomy. Positive surgical margin rates of radical prostatectomy affect the recurrence and survival of prostate cancer. The urinary and sexual function outcomes have been vastly improved. Neoadjuvant treatment only affects the rate of positive surgical margin. Adjuvant therapy can delay and reduce the risk of recurrence and improve the survival of the high risk prostate cancer. Conclusions. For the majority of patients with organ-confined prostate cancer, radical prostatectomy remains a most effective approach. Radical perineal prostatectomy remains a viable approach for patients with morbid obesity, prior pelvic surgery, or prior pelvic radiation. Robot-assisted laparoscopic prostatectomy (RALP) has become popular among surgeons but has not yet become the firmly established standard of care. Long-term data have confirmed the efficacy of radical retropubic prostatectomy with disease control rates and cancer-specific survival rates.Item Open Access Hormone naïve prostate cancer: predicting and maximizing response intervals.(Asian journal of andrology, 2015-11) Moul, Judd WHormone naïve advanced prostate cancer is subdivided into two disease states: biochemical recurrence and traditional M1 (metastatic) prostate cancer and characterized by no prior hormonal therapy or androgen deprivation therapy (ADT). In biochemical recurrence/prostate-specific antigen (PSA) recurrence, men should be risk-stratified based on their PSA doubling time, the Gleason score and the timing of the recurrence. In general, only men who are at high risk should be considered for early/immediate ADT although this is best done using shared decision with the patient. The type of ADT to be used in biochemical recurrence ranging from oral-only peripheral blockade (peripheral androgen deprivation) to complete hormonal therapy (combined androgen blockade [CAB]) remains in debate owing to lack of randomized controlled trials (RCT). However, there is good RCT support for use of intermittent hormonal therapy (IHT). There is also limited research on biomarker response (PSA and testosterone decline) to predict prognosis. On the other hand, in the setting of M1 hormone naïve prostate cancer, there are many more RCT's to inform our decisions. CAB and gonadotrophin-releasing hormone antagonists perhaps provide a slight efficacy advantage while IHT may be slightly inferior with minimal M1 disease. The PSA nadir at 7 months after starting ADT is a powerful prognostic tool for M1 patients. There is growing recognition that serum testosterone (T) control while on ADT is linked to the development of castrate-resistant prostate cancer. Especially for a M1 patient, maintaining a serum T below 20-30 ng dl-1 prolongs the response to ADT. Novel oral agents (abiraterone and enzalutamide) may soon find use in hormone naïve disease and may alter the treatment landscape. Despite over 75 years of experience with ADT, many questions remain, and the field continues to evolve.Item Open Access How I do it: Apalutamide use in non-metastatic castrate resistant prostate cancer.(The Canadian journal of urology, 2019-06) Moul, Judd WUrologists have been using oral nonsteroidal antiandrogens (AA) for 30 years as a component of combined androgen blockade. In February 2018, a new third generation AA, apalutamide, became available for the first time for non-metastatic (M0) castrate resistant prostate cancer (CRPC). Apalutamide was found to delay the presence of metastases (metastases free survival-MFS) by approximately 2 years versus placebo in M0 CRPC. While overall survival benefit has yet to be established, the MFS benefit is clinically meaningful and urology practices should be equipped to manage patients using this new oral agent. Since the majority of patients remain under urologic care when this disease stage develops and because the drug is straightforward to administer, urology practices are ideal to identify and treat. The objective of this brief article is to discuss the typical patient profile for use of apalutamide and to review the pros and cons of use and common side effects and management.Item Open Access Management of prostate cancer in older men: recommendations of a working group of the International Society of Geriatric Oncology.(BJU Int, 2010-08) Droz, Jean-Pierre; Balducci, Lodovico; Bolla, Michel; Emberton, Mark; Fitzpatrick, John M; Joniau, Steven; Kattan, Michael W; Monfardini, Silvio; Moul, Judd W; Naeim, Arash; van Poppel, Hendrik; Saad, Fred; Sternberg, Cora NProstate cancer is the most prevalent cancer in men and predominantly affects older men (aged >or=70 years). The median age at diagnosis is 68 years; overall, two-thirds of prostate cancer-related deaths occur in men aged >or=75 years. With the exponential ageing of the population and the increasing life-expectancy in developed countries, the burden of prostate cancer is expected to increase dramatically in the future. To date, no specific guidelines on the management of prostate cancer in older men have been published. The International Society of Geriatric Oncology (SIOG) conducted a systematic bibliographic search based on screening, diagnostic procedures and treatment options for localized and advanced prostate cancer, to develop a proposal for recommendations that should provide the highest standard of care for older men with prostate cancer. The consensus of the SIOG Prostate Cancer Task Force is that older men with prostate cancer should be managed according to their individual health status, which is mainly driven by the severity of associated comorbid conditions, and not according to chronological age. Existing international recommendations (European Association of Urology, National Comprehensive Cancer Network, and American Urological Association) are the backbone for localized and advanced prostate cancer treatment, but need to be adapted to patient health status. Based on a rapid and simple evaluation, patients can be classified into four different groups: 1, 'Healthy' patients (controlled comorbidity, fully independent in daily living activities, no malnutrition) should receive the same treatment as younger patients; 2, 'Vulnerable' patients (reversible impairment) should receive standard treatment after medical intervention; 3, 'Frail' patients (irreversible impairment) should receive adapted treatment; 4, Patients who are 'too sick' with 'terminal illness' should receive only symptomatic palliative treatment.Item Open Access Managing Prostate Cancer Surgical Patients during the COVID-19 Pandemic: A Brief Report of the Duke Cancer Institute's Initial Experience.(Oncology (Williston Park, N.Y.), 2020-05) Moul, Judd W; Chang, Andrew; Inman, Brant AThe coronavirus disease 2019 pandemic has rapidly placed tremendous stress on health systems around the world. In response, multiple health systems have postponed elective surgeries in order to conserve hospital beds and personal protective equipment, minimize patient traffic, and prevent unnecessary utilization and exposure of healthcare workers. The American College of Surgeons released the following statement on March 13, 2020: "Each hospital, health system and surgeon should thoughtfully review all scheduled elective procedures with a plan to minimize, postpone, or cancel electively scheduled operations, endoscopes, or other invasive procedures until we have passed the predicted inflection point in the exposure graph and can be confident that our health care infrastructure can support a potentially rapid and overwhelming uptick in critical patient care needs." In our state, North Carolina, Governor Roy Cooper requested that all hospitals postpone elective and non-urgent procedures and surgeries effective March 23, 2020.Item Open Access Postoperative changes in cognition and cerebrospinal fluid neurodegenerative disease biomarkers.(Annals of clinical and translational neurology, 2022-02) Berger, Miles; Browndyke, Jeffrey N; Cooter Wright, Mary; Nobuhara, Chloe; Reese, Melody; Acker, Leah; Bullock, W Michael; Colin, Brian J; Devinney, Michael J; Moretti, Eugene W; Moul, Judd W; Ohlendorf, Brian; Laskowitz, Daniel T; Waligorska, Teresa; Shaw, Leslie M; Whitson, Heather E; Cohen, Harvey J; Mathew, Joseph P; MADCO-PC InvestigatorsObjective
Numerous investigators have theorized that postoperative changes in Alzheimer's disease neuropathology may underlie postoperative neurocognitive disorders. Thus, we determined the relationship between postoperative changes in cognition and cerebrospinal (CSF) tau, p-tau-181p, or Aβ levels after non-cardiac, non-neurologic surgery in older adults.Methods
Participants underwent cognitive testing before and 6 weeks after surgery, and lumbar punctures before, 24 h after, and 6 weeks after surgery. Cognitive scores were combined via factor analysis into an overall cognitive index. In total, 110 patients returned for 6-week postoperative testing and were included in the analysis.Results
There was no significant change from before to 24 h or 6 weeks following surgery in CSF tau (median [median absolute deviation] change before to 24 h: 0.00 [4.36] pg/mL, p = 0.853; change before to 6 weeks: -1.21 [3.98] pg/mL, p = 0.827). There were also no significant changes in CSF p-tau-181p or Aβ over this period. There was no change in cognitive index (mean [95% CI] 0.040 [-0.018, 0.098], p = 0.175) from before to 6 weeks after surgery, although there were postoperative declines in verbal memory (-0.346 [-0.523, -0.170], p = 0.003) and improvements in executive function (0.394, [0.310, 0.479], p < 0.001). There were no significant correlations between preoperative to 6-week postoperative changes in cognition and CSF tau, p-tau-181p, or Aβ42 changes over this interval (p > 0.05 for each).Interpretation
Neurocognitive changes after non-cardiac, non-neurologic surgery in the majority of cognitively healthy, community-dwelling older adults are unlikely to be related to postoperative changes in AD neuropathology (as assessed by CSF Aβ, tau or p-tau-181p levels or the p-tau-181p/Aβ or tau/Aβ ratios).Trial registration
clinicaltrials.gov (NCT01993836).Item Open Access Prostate cancer: an evolving paradigm.(J Endourol, 2010-05) Caso, Jorge R; Mouraviev, Vladimir; Tsivian, Matvey; Polascik, Thomas J; Moul, Judd WSince at least the early 1990s, stage and risk migration have been seen in patients with prostate cancer, likely corresponding to the institution of prostate specific antigen (PSA) screening in health systems. Preoperative risk factors, including PSA level and clinical stage, have decreased significantly. These improved prognostic variables have led to a larger portion of men being stratified with low-risk disease, as per the classification of D'Amico and associates. This, in turn, has corresponded with more favorable postoperative variables, including decreased extraprostatic tumor extension and prolonged biochemical-free recurrence rates. The advent of focal therapy is bolstered by findings of increased unilateral disease with decreased tumor volume. Increasingly, targeted or delayed therapies may be possible within the current era of lower risk disease.Item Open Access Prostatic alpha-linolenic acid (ALA) is positively associated with aggressive prostate cancer: a relationship which may depend on genetic variation in ALA metabolism.(PLoS One, 2012) Azrad, Maria; Zhang, Kui; Vollmer, Robin T; Madden, John; Polascik, Thomas J; Snyder, Denise C; Ruffin, Mack T; Moul, Judd W; Brenner, Dean; Hardy, Robert W; Demark-Wahnefried, WendyPrevious observational studies have reported associations between prostate cancer and alpha-linolenic acid (ALA). However, few investigations have been able to study this relationship prospectively and in well-controlled settings. Moreover, no studies have determined whether single nucleotide polymorphisms (SNPs) that influence ALA metabolism are associated with this common cancer. The purpose of this study was to explore associations between prostatic levels of ALA, SNPs and prostate cancer-specific biomarkers in samples collected from a previous randomized clinical trial conducted using a presurgical model and which tested the effects of flaxseed supplementation, a rich source of ALA, prior to prostatectomy (n = 134). Serum prostate-specific antigen (PSA) was determined and immunohistochemistry was used to assess tumor proliferation rate (Ki67). Prostatic ALA was determined with gas chromatography. Seven previously identified SNPs associated with delta-6 desaturase activity (rs99780, rs174537, rs174545, rs174572, rs498793, rs3834458 and rs968567) were tested for associations with prostatic ALA, PSA and Ki67. Despite consuming seven times more ALA per day, men in the flaxseed arm had similar amounts of prostatic ALA relative to men not consuming flaxseed. In unadjusted analysis, there were significant positive associations between prostatic ALA and PSA (ρ = 0.191, p = 0.028) and Ki67 (ρ = 0.186, p = 0.037). After adjusting for covariates (flaxseed, age, race, BMI and statin-use) the association between ALA and PSA remained (p = 0.004) but was slightly attenuated for Ki67 (p = 0.051). We did not observe associations between any of the SNPs studied and prostatic ALA; however, in models for PSA there was a significant interaction between rs498793 and ALA and for Ki67 there were significant interactions with ALA and rs99780 and rs174545. Independent and inverse associations were observed between rs174572 and Ki67. This study provides evidence that prostatic ALA, independent of the amount of ALA consumed, is positively associated with biomarkers of aggressive prostate cancer and that genetic variation may modify this relationship.Item Open Access Reply by Authors.(Urology practice, 2020-09) Han, Tracy; Gagnon, Jennifer; Barth, Pamela; Schilder, Mary; Goldstein, Ben; Faerber, Gary; Lipkin, Michael; Moul, Judd WItem Open Access Successful Diagnosis and Treatment of Occult Prostate Cancer Despite Multiple Negative Prostate Biopsies and Negative Prostate MRIs.(Oncology (Williston Park, N.Y.), 2022-03) Morris, Kostantinos E; Grimberg, Dominic C; Gupta, Rajan T; Pendse, Avani A; Moul, Judd WProstate-specific antigen (PSA) values above 100 ng/mL often suggest metastatic prostate cancer. We present the case of a patient with a PSA of 110 ng/mL, 4 negative prostate biopsies, and 4 negative prostate MRIs. After his fifth MRI revealed a PI-RADS 5 lesion, he underwent his fifth transrectal biopsy; this revealed Gleason 3 + 4 = 7. He was found to have organ-confined pT2 disease on subsequent radical prostatectomy pathology. This case highlights that there may be no PSA for which one can assume metastatic disease with certainty. Depending on life expectancy, patients with extremely elevated PSA may still warrant a full staging workup.Item Open Access The type of ADT may matter for testosterone recovery.(The Canadian journal of urology, 2021-08) Moul, Judd W
