PSA bounce phenomenon after External Beam Radiation Therapy for prostate cancer.
Journal Title: Współczesna Onkologia - Year 2007, Vol 11, Issue 3
Abstract
Introduction to clinical practice of PSA antigen altered the therapeutic approach to treatment of prostate cancer. The PSA antigen was defined as sensitive marker for monitoring of prostate cancer. At treated with radiotherapy patients (EBRT) value of PSA nadir after treatment is the significant determinant of results of treatment statistically. Three consecutive PSA rise above the post-treatment nadir have been defined as biochemical failure by the American Society for Therapeutic Radiology and Oncology (ASTRO) consensus panel. However a single rise in post-EBRT PSA level continues to be a source of considerable anxiety due to the intriguing uncertainty of relationship between PSA bouncing and disease relapse. The clinical practice show that growth of level PSA after radiotherapy was possible and does not it join with progression of disease. Phenomenon this was named as “PSA-bounce”. Various definitions of PSA bounce have been used in the literature. The authors in presented work represent the current state of knowledge on this phenomenon after use radical External Beam Radiation Therapy.
