Biochemical (Prostate-Specific Antigen) Relapse: An Oncologist's Perspective.

Mary-Ellen Taplin

    Reviews in Urology
    |September 21, 2006
    PubMed
    Summary

    Defining biochemical relapse after prostate cancer treatment remains unclear. Early prostate-specific antigen (PSA) rise signals recurrence, but treatment options lack proven benefits, necessitating clinical trials.

    Area of Science:

    • Oncology
    • Urology

    Background:

    • The definition of biochemical relapse after prostatectomy lacks consensus, with varying prostate-specific antigen (PSA) thresholds.
    • PSA measurements post-radiation are less predictable, yet PSA levels indicate occult cancer recurrence.

    Purpose of the Study:

    • To review features of PSA relapse after prostatectomy and radiation.
    • To evaluate current and future treatment options for biochemical relapse.
    • To emphasize the need for clinical trials to establish care standards.

    Main Methods:

    • Review of retrospective, single-institution trials.
    • Analysis of PSA doubling time and time to PSA elevation.
    • Examination of various treatment modalities for biochemical relapse.

    Main Results:

    • PSA relapse does not always equate to clinical relapse or cancer-specific mortality.
    • PSA doubling time and time to PSA elevation correlate with clinical progression.
    • No current treatment for biochemical failure offers proven benefits in quality of life, metastasis-free survival, or overall survival.

    Conclusions:

    • Observation or hormone therapy are current options for biochemical relapse, depending on PSA doubling time and patient factors.
    • Early chemotherapy combined with hormone therapy shows promise.
    • Enrollment in clinical trials is crucial for developing evidence-based standards of care for prostate cancer biochemical relapse.
