Emerging Research in Prostate Cancer Imaging — October 2024

For patients who received radiotherapy for localized prostate cancer, total intraprostatic tumor volume derived from AI segmentation had a 10 percent higher AUC for predicting seven-year metastases in comparison to a risk model from the National Comprehensive Cancer Network (NCCN).

For patients with biochemical recurrence of prostate cancer, PSMA PET imaging may facilitate a 12.8 percent lower incidence of prostate cancer mortality in contrast to the combination of CT and bone scan, according to long-term outcome estimates from a new decision-analytic modeling study.

Earlier detection of PSMA-avid lesions in post-radiotherapy patients with increases in PSA levels < 2 ng/ml above nadir were reportedly associated with a significantly lower incidence of distant metastases and lower overall mortality rates.

When employing a PI-RADS > 4 cutoff, researchers found that the mdprostate software provided an 85.5 percent sensitivity rate for diagnosing clinically significant prostate cancer on mpMRI.

In a recent interview, Lisa F. Newcomb, Ph.D., discussed the merits of active surveillance for low-risk prostate cancer (PCa) and key findings from multicenter research involving over 2,100 men with localized PCa.

PSMA PET/CT revealed progressive PCa in 31 percent of patients who demonstrated greater than a 50 percent decline in PSA level after treatment with either an androgen receptor-targeted agent or chemotherapy.
