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

Aidan Kennedy Jason 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.

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

Benjamin H. Lowentritt Ibrahim Khilfeh Dominic Pilon Shawn Du Carmine Rossi Frederic Kinkead Lilian Diaz Jill Korsiak Patrick Lefebvre Gordon 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.

Prostate Biopsy Features: A Comparison Between the Pre– and Post–2012 United States Preventive Services Task Force Prostate Cancer Screening Guidelines With Emphasis on African American and Septuagenarian Men

Vladimir Ioffe Navin Shah Shannon Cherone

We compare prostate biopsy (Pbx) characteristics from 3 years prior to the 2012 United States Preventive Services Task Force (USPSTF) prostate cancer (PCa) screening guidelines with those of 2018, with a focus on African American (AA) men and healthy men aged 70 to 80 years. We completed a retrospective comparative analysis of 1703 sequential patients that had had a Pbx from 2010 to 2012 (3 years) with 383 patients biopsied in 2018. Data was collected on patient age, race, prostate-specific antigen (PSA), digital rectal examination (DRE), total number of biopsies performed, and Gleason sum score (GSS). The data was analyzed to determine whether the 2012 USPSTF screening recommendations affected PCa characteristics. Two study groups were defined as group A and B, Pbx prior to the 2012 USPSTF screening guidelines and that of 2018, respectively. The study population consisted of 71% high-risk AA patients. In Group A (pre-2012 USPSTF guidelines), 567 patients/year underwent a Pbx versus Group B, 383 patients/year, a 32% reduction post-USPSTF. The annual positive Pbx rate for Group A is 134/year versus Group B with 175/year, a 31% increase post-USPSTF. In Group B, there was a 94% relative increase in total positive biopsies. Group A had high-grade PCa (GSS 7-10) in 51.5% versus 60.5% in Group B, a 9% increase post-USPSTF. The proportion of patients with a PSA 10 ng/mL or higher was 25.4% in group A versus 29.3% in group B. The age group of 70 to 80 years demonstrated an increasing trend for patients with PSA 10 ng/mL and higher, 31% in Group A versus 38% in Group B; high-grade tumors (GSS 7-10) occurred in 61% in Group A versus 65% in Group B. After the 2012 USPSTF guidelines against PCa screening, our study shows decreased prostate cancer screening with decreased Pbx, increased PCa diagnosis, and increased high-grade (GSS 7-10) PCa. These trends were especially notable in the 70- to 80-year age group, which showed a larger proportion of total patients (compared with pre-2012 USPSTF guidelines), increased PCa grades, increased PSA levels, and a higher percentage of patients with greater than 50% positive cores. As our patient population consists of 71% AA patients, our results support aggressive PCa screening for high-risk patients, which includes AA men, men with a family history of PCa, and healthy men aged 70 to 80 years.
