Siemens has become aware that serial psa measurements at values <0.2ng/ml are being used to monitor patients for biochemical recurrence of prostate cancer post-radical prostatectomy. the risk to health is limited to scenarios where the threshold for biochemical recurrence is defined independent of the 2013 american urological association (aua) guidelines or 2015 european association of urology (eau) guidelines which define recurrence of prostate cancer as a detectable or rising psa value post-radical prostatectomy that is =0.2 ng/ml (ug/l) with a second confirmatory level of =0.2 ng/ml (ug/l). in scenarios, where clinicians use the psa assay in accordance with clinical guidelines for biochemical recurrence there is negligible risk to health.In a recent study, the limit of quantitation (loq) level for the advia centaur/xp/xpt psa assay was evaluated and determined to be 0.04 ng/ml at the level of 20% within laboratory precision. this applies to all lots of advia centaur psa.

Siemens is providing a letter to emphasize that PSA values should be interpreted in accordance with current clinical guidelines for defining biochemical recurrence following radical prostatectomy. The use of PSA thresholds < 0.2 ng/mL (ug/L) to identify biochemical recurrence of prostate cancer is not recommended. Where clinicians decide to use a PSA value <0.2 ng/mL (ug/L) as a threshold for identifying patients who may be experiencing biochemical recurrence, the potential exists for unnecessary follow-up &/or treatment for progression of residual disease. Any clinician choosing to use PSA in this manner should be aware of current clinical guidance & the limitations of PSA assays. Siemens is advising users to review the information with the lab's Medical Director. Siemens is not recommending a lab review of previously generated results; however, this is at the discretion of the lab.
