Prostate specific antigen bounce after intensity-modulated radiation therapy in an Asian population

摘要

ObjectiveSerum prostate specific antigen (PSA) is commonly used to evaluate treatment response after definitive radiation therapy (RT). However, PSA levels can temporarily rise without a clear reason, termed “PSA bounce”, and often engender great anxiety for both patients and physicians. The present study aimed to determine the prevalence and factors that predict “PSA bounce” after intensity-modulated radiation therapy (IMRT), and the relevance to biochemical failure and cancer recurrence in an Asian population.
