Changing PSA's Link with Recurrence after External Beam Radiation

[Guest guest]

4,247 prostate cancer patients were analyzed and 339 (12.2%) had clinical

recurrences. The median number of PSA measurements was 9. Regarding PSA

pattern and its determinants, for ptPSA only iPSA was of statistical

significance with higher pretreatment PSA levels corresponding to

higher post-treatment PSA levels. iPSA and T-stage were significantly

associated with the short-term PSA decline after XRT. iPSA, T-stage and

Gleason score all had higher values, corresponding to higher rates of

long-term PSA rise. Click on the below link for the full story:<http://www.medicalnewstoday.com/articles/133737.php>
