ROCHESTER, Minn. -- Mayo Clinic researchers have identified the first immune molecule that appears to play a role in prostate cancer development and in predicting cancer recurrence and progression after surgery. The report on the B7-H3 molecule by Mayo Clinic Cancer Center appears today in Cancer Research.

“This discovery will allow physicians to individualize treatment and observation plans for prostate cancer patients,” says Timothy Roth, M.D., a Mayo Clinic urology resident and lead author of the study. “Being able to tell a patient his specific risk after surgery, and perhaps even prior to surgery, will be a huge step forward.”
