Risk factors for Gleason score changes between biopsy pathology and radical prostatectomy specimen / 中华泌尿外科杂志

ABSTRACT

Gleason grading system is a critical factor for assessing the risk, making treatment decision and evaluating prognosis for patients with prostate cancer. However, it has been reported that concordance rates of Gleason score between biopsy pathology and radical prostatectomy specimen were only39%-63%, whilst postsurgical upgrade and downgrade rates were 30%-55% and 7%-20% respectively. This situation brings difficulties in performing clinical practice. This literature aimed to review relevant and updated studies in literature to summarize the concordance rate and independent predictive factors of Gleason score change from following several aspects: patient clinical characteristics, biopsy-related factors, accuracy of pathologic assignment and interpretation of pathology reports. This review also investigated how the factors influenced the Gleason score change and clinical decision-making. There were many factors influencing the Gleason score change which were roughly consistent with risk factors of prostate cancer, however, some factors were controversial. In order to provide precise evaluation of risk stratification and optimal individualized treatment, it is essential to consider the risk factors which are correlated with Gleason score change.
