Changes In Benign Tissue Next To Prostate Tumors May Predict Biochemical Recurrence Of Cancer, Scientists Find

Changes in benign tissues next to prostate tumors may provide an early warning for patients at higher risk for biochemical recurrence after a radical prostatectomy, a study by researchers at Case Western Reserve University and Johns Hopkins Medical Institutions shows.

Biochemical recurrence, which is increasing prostate-specific antigen (PSA) levels, can be used to predict which prostate cancer patients will develop local recurrence, distant metastases and death.

In a small sampling, image analysis of the adjacent tissue was a better predictor than the current standard for prognosis following the prostatectomy.

If preliminary findings are confirmed by further studies, they may help doctors decide sooner which patients need more follow-up therapies after surgery or should return for more regular monitoring.

“In a sense, this study is validating what a lot of people think regarding these cancers—that there is a field effect, as if the tumor has hard-to-see tentacles that can affect the patient and outcomes,” said Anant Madabhushi, the F. Alex Nason professor II of biomedical engineering at Case Western Reserve and leader of the research.
