BackgroundOver the past decade, significant updates have been made regarding the classification and grading of prostate adenocarcinoma in radical prostatectomy specimens, following decisions reached in international conferences and through impactful publications. These alterations are closely linked to patient prognosis.ObjectivesObserve the incidence of these changes and their impact on patient prognosis. Additionally, investigate the relationship between histopathological and clinical parameters to assist in multidisciplinary treatment planning.DesignRetrospective cohort study.SettingTertiary university hospital.MethodsHematoxylin and eosin, along with immunohistochemistry stained sections, were reevaluated, and clinical information, including patient demographics, preoperative PSA levels, and patient follow-up were collected from patients who underwent radical prostatectomy at our center.Sample Size182 patients.Main Outcome MeasuresBiochemical recurrence.ResultsThe study highlighted the negative prognostic effects of factors such as Gleason grade group, lymphovascular invasion, intraductal carcinoma, positive surgical margins, extraprostatic extension, pathological T stage, and seminal vesicle invasion. These factors are important determinants of recurrence-free survival in prostate adenocarcinoma patients.ConclusionThis study identified comedonecrosis and intraductal carcinoma as independent negative prognostic factors. A 3-mm cutoff for positive surgical margins was supported, while the current cutoff for extraprostatic extension may require reevaluation. The impact of cribriform pattern and ductal carcinoma appears to be influenced by the grade group. No independent relationship was found between the Gleason score/pattern on positive surgical margins or extraprostatic extension and prognosis. Further, large-scale studies with long-term follow-up are needed.LimitationsThe study is limited by the relatively small number of patients for certain parameters.
