![]() ![]() “These patients are ending up with clinically significant prostate cancer not in five or 10 years, but in a short time,” Dr. Results also showed that the mean time from MRI to diagnosis in the patients who were determined to have clinically significant prostate cancer was nine months. Of the 292 patients with available follow up pathology and medical reports, 26% were diagnosed with clinically significant prostate cancer, 51% had non-clinically significant prostate cancer and 23% had no prostate cancer. Of those patients, 90% had a biopsy, 8% had a prostatectomy and 2% underwent a transurethral resection. The retrospective study found that 292 patients with a PI-RADS 3 score underwent 713 procedures. Out of 3,238 MRI exams, 423 patients had a PI-RADS 3 score. The team examined all prostate MRI exams at Brigham and Women’s Hospital performed between 20 with a PI-RADS 3 score. Salah and colleagues sought to determine the incidence of clinically significant prostate cancer in patients with a PI-RADS v2 assessment category 3 based on their prostate multiparametric MRI. PI-RADS 3 Patients Require Plan for Care Managementĭr. “Practice variability can create confusion, diagnosis delay or unnecessary procedures,” Dr. But that can vary from patient to patient. Typically, when a patient receives a PI-RADS 3 rating the next step is to speak with the person’s doctor about other risk factors and evaluate possible next steps. PI-RADS 5: clinically significant cancer is highly likely to be present.PI-RADS 4: clinically significant cancer is likely to be present.PI-RADS 3: the presence of clinically significant cancer is equivocal.PI-RADS 2: clinically significant cancer is unlikely to be present.PI-RADS 1: clinically significant cancer is highly unlikely to be present.In the PI-RADS scale, each lesion is assigned a score from 1 to 5 indicating the likelihood of clinically significant cancer. PI-RADS is used to standardize interpretation of prostate MRI, improve early diagnosis and treatment, and reduce unnecessary biopsies. “PI-RADS 3 is a common category but it’s problematic because there are no specific guidelines for what the next steps should be.” “Those patients are more challenging,” Dr. However, PI-RADS v2 doesn’t provide guidelines to aid in clinical decision-making for patients with intermediate scores, making it more difficult to develop a timely plan for care, said Fatima Salah, MD, a clinical fellow at Brigham and Women’s Hospital in Boston, and colleagues in her RSNA 2020 session, “Understanding Prostate MR PI-RADS 3: A Longitudinal Study.” Patients who receive an intermediate score of the Prostate Imaging Reporting and Data System (PI-RADS) scale, or PI-RADS 3, have a substantial chance of developing clinically significant prostate cancer, new research shows. ![]()
