Prostate-Specific Antigen: Any Successor in Sight?

Diagnostic Review

Aniebietabasi S ObortMary B AjadiOluyemi Akinloye

Prostate cancer (PCa) is the most frequently diagnosed malignancy and the second leading cause of cancer death in men in the United States and other parts of the world. The lifetime risk of being diagnosed with PCa is approximately 16%. At present, the only widely accepted screening tools for PCa are prostate-specific antigen (PSA) and digital rectal examination. PSA is known to be prostate specific, but not PCa specific, and hence lacks the sensitivity to detect a large number of tumors, especially during the early stages. The PSA level is also known to be affected by many factors, such as medication, inflammation (benign prostatic hyperplasia and prostatitis), and urologic manipulation; hence, the controversy regarding the appropriate level of serum PSA that should trigger a biopsy or have clinical relevance to prostate metastases. Attempts to determine the level of prostate cells in peripheral blood by reverse transcriptase polymerase chain reaction did not significantly improve cancer diagnosis or predict postoperative failure. Therefore, the search continues for a novel biomarker or a panel of markers as well as other possible interventions to improve the use of PSA. This article reviews several possibilities.

The Use of Biomarkers in Prostate Cancer Screening and Treatment

Treatment Update

Joseph Renzulli IIAshley V AlfordJoseph M Brito IIIKamlesh K YadavShalini S YadavAshutosh K Tewari

Prostate cancer screening and diagnosis has been guided by prostate-specific antigen levels for the past 25 years, but with the most recent US Preventive Services Task Force screening recommendations, as well as concerns regarding overdiagnosis and overtreatment, a new wave of prostate cancer biomarkers has recently emerged. These assays allow the testing of urine, serum, or prostate tissue for molecular signs of prostate cancer, and provide information regarding both diagnosis and prognosis. In this review, we discuss 12 commercially available biomarker assays approved for the diagnosis and treatment of prostate cancer. The results of clinical validation studies and clinical decision-making studies are presented. This information is designed to assist urologists in making clinical decisions with respect to ordering and interpreting these tests for different patients. There are numerous fluid and biopsy-based genomic tests available for prostate cancer patients that provide the physician and patient with different information about risk of future disease and treatment outcomes. It is important that providers be able to recommend the appropriate test for each individual patient; this decision is based on tissue availability and prognostic information desired. Future studies will continue to emphasize the important role of genomic biomarkers in making individualized treatment decisions for prostate cancer patients.

Exceptional Response to Radiation Therapy to the Primary Tumor in a Patient With de Novo Metastatic Prostate Cancer With High Tumor Mutation Burden

Benjamin MercierAndrew TamDaniela V. CastroSalvador Jaime-CasasAbhishek TripathiYun Rose LiRegina Barragan-Carrillo

We present the case of a patient diagnosed with de novo, low-volume metastatic prostate cancer who received first-line treatment with androgen-deprivation therapy in combination with darolutamide. The patient presented with symptoms derived from local growth from the primary tumor and received pelvic radiation therapy to the primary tumor and pelvic nodes. He experienced complete tumor regression, with high serum prostate-specific antigen declining to nondetectable levels. Next-generation genomic analysis indicated high tumor mutation burden and high microsatellite status instability. Here, we contextualize this patient’s case regarding the importance of precision genomics in radiation oncology and its potential importance for optimizing treatment.

Incorporation of IsoPSA Into Clinical Practice in the Management of Elevated Prostate-Specific Antigen Based on Current Guidelines

Aidan KennedyJason Hafron

Prostate cancer is a highly prevalent malignancy among men worldwide. Optimal management depends on early detection and accurate surveillance. Several screening and surveillance tools are available to men with prostate cancer, including prostate-specific antigen (PSA) testing, digital rectal examination, prostate biopsy, imaging modalities, and a plethora of biomarkers. Prostate-specific antigen, though widespread in its use, is limited in its specificity. Many adjunctive tests to PSA have been developed. One such test is IsoPSA (Cleveland Diagnostics), a novel PSA assay that focuses on structural differences among PSA isoforms to aid in detecting clinically significant prostate cancer. With an improved understanding of the capability and uses of IsoPSA, physicians can enhance patient outcomes through more accurate risk assessment and save costs by reducing the number of unnecessary prostate biopsies and imaging generated resulting from a nonspecific elevation in serum PSA. This review describes the performance and use of IsoPSA.

Prostate Cancer: Epidemiology, Screening, and Biomarkers

16th International Prostate Cancer Update

Gerald W Chodak

Carcinoma of the prostate continues to be a major health problem in the United States. Beginning in 1988, a marked increase in detection of prostate cancer occurred due to the development of a test for prostate-specific antigen (PSA). Controversy exists, however, about the value of PSA as a tumor marker. Although it has prognostic significance both before and after definitive therapy for prostate cancer, it is unclear whether routine PSA screening will translate into a survival advantage for patients. Because of its limitations, PSA may not ultimately be a good enough marker to be used as a screening tool. However, molecular biology has led to a rapid rise in the number of potential new prostate tumor markers, which may eventually overcome the weaknesses of PSA. Considerable progress has occurred in the diagnosis and management of prostate cancer: more is understood about the risk factors for the disease, possible ways to prevent it, and new ways to diagnose and monitor it. These developments have already translated into better patient care, while also identifying where further improvements are needed. [Rev Urol. 2006;8(suppl 2):S3-S8]

A Trend Toward Aggressive Prostate Cancer

Original Research

Navin ShahVladimir Ioffe

To compare prostate biopsy (Pbx) characteristics before and after the 2012 United States Preventive Services Task Force (USPSTF) prostate cancer (PCa) screening guidelines, we completed a retrospective comparative analysis of 1703 sequential patients that had a Pbx in 2010 to 2012 (3 years) with 383 patients biopsied in 2018 and 310 patients biopsied in 2019. Data was collected on patient age, race, serum prostate specific antigen (PSA) level, digital rectal examination (DRE) results, total number of biopsies performed, and Gleason sum score (GSS). Data were analyzed to determine whether the 2012 USPSTF screening recommendations against PCa screening may have affected PCa characteristics. Three study groups were defined as Group A, Group B, and Group C. Group A represents Pbx prior to the 2012 USPSTF screening guidelines (2010-2012), Group B represents Pbx in 2018, and Group C represents Pbx in 2019. The patient population consisted of 73% Black men, 16% White men, and 11% men of other races. The number of patients that had a biopsy in Groups A through C, respectively, were 567 patients/year, 383 patients/year, and 310 patients/year. The annual positive Pbx rate for Group A through C was 134/year, 175/year, and 201/year, respectively. High-grade PCa (GSS 7-10) in Groups A through C was 51.5%, 60.5%, and 60.0%. The proportion of patients with a serum PSA level 10 ng/mL or greater in Groups A through C was 25.4%, 29.3%, and 33%. For patients age 70 to 80 years, there was an increasing trend for serum PSA levels 10 ng/mL and higher: 31%, 38%, and 39%, respectively. In this age group, high-grade tumors (GSS 7-10) occurred in 61%, 65%, and 68%, respectively. In 2019, Grade Group 3, 4, and 5 was present in 37.7% of 70- to 80-year-old men and 34.6% of Black men. More than 50% positive biopsy cores were present in 46.3% of 70- to 80-year-old men and 36.6% of Black men. Our data through 2019 continued to show that after the 2012 USPSTF recommendations against PCa screening, PCa screening has decreased. We found decreased Pbx, increased PCa diagnosis, and increased high-grade PCa (GSS 7-10). As our patient population consisted of 73% Black patients and 33% of men age 70 to 80 years, our results support aggressive PCa screening for high-risk patients, which include Black men, men with a family history of PCa, and healthy men age 70 to 80 years.

Real-World Comparison of Deep Prostate-Specific Antigen Response in Patients With Metastatic Castration-Sensitive Prostate Cancer Treated With Apalutamide or Enzalutamide

Benjamin H. LowentrittIbrahim KhilfehDominic PilonShawn DuCarmine RossiFrederic KinkeadLilian DiazJill KorsiakPatrick LefebvreGordon A Brown

Deep prostate-specific antigen reduction of at least 90% (PSA90 response) after androgen receptor pathway inhibitor initiation to treat metastatic castration-sensitive prostate cancer (mCSPC) is associated with longer survival. This real-world study evaluated the proportion of androgen receptor pathway inhibitor–naive patients with mCSPC who achieved PSA90 response 6 months after initiating apalutamide or enzalutamide.

Role of Inflammation in Benign Prostatic Hyperplasia

Disease State Review

Steven A KaplanRichard LeeBilal ChughtaiAlexis E Te

Inflammation of the prostate may represent a mechanism for hyperplastic changes to occur in the prostate. There are a variety of growth factors and cytokines that may lead to a proinflammatory process within the prostate. There are several proposed mechanisms that lead to both the intrinsic and extrinsic basis of inflammation. Prostatic inflammation may represent an important factor in influencing prostatic growth and progression of symptoms. This article reviews the recent literature on inflammation leading to chronic prostatic diseases, such as benign prostatic hyperplasia.

Management of Localized Prostate Cancer and an Incidental Ureteral Duplication With Upper Pole Ectopic Ureter Inserting into the Prostatic Urethra

Case Review

Ellen ShapiroHerbert LeporJonathan MelamedTracy P MarienMichael D StifelmanBachir Taouli

Ectopic ureters are rare congenital malformations of the renal system that most commonly present in females. It is extremely rare to encounter an ectopic ureter in an older man undergoing radical prostatectomy. We report herein a case of a 66-year-old man with prostate cancer and a complete duplication of the left renal collecting system, with an upper pole ectopic ureter and associated normal functioning renal parenchyma entering into the prostatic urethra. This anomaly was incidentally discovered on preoperative magnetic resonance imaging of the prostate. Open radical retropubic prostatectomy and a left ureteroureterostomy were performed.
