ABSTRACT
PURPOSE:
Prostatic adenocarcinoma with cribriform morphology and/or intraductal carcinoma has higher recurrence and mortality rates after radiation and surgery. While the prognostic impact of these features is well studied, concordance with cribriform morphology and/or intraductal carcinoma on biopsy and prostatectomy has only recently gained attention. Our primary objective was to evaluate the diagnostic performance of biopsy to detect cribriform morphology and/or intraductal carcinoma in paired biopsy and prostatectomy specimens in a large contemporary cohort. MATERIALS ANDMETHODS:
Patients who underwent prostate biopsy or had biopsies reviewed prior to prostatectomy at a tertiary hospital between November 2017 and November 2018 were included in study. Sensitivity and specificity were calculated to assess concordance with cribriform morphology and/or intraductal carcinoma on biopsy and prostatectomy. The association of biopsy diagnosed with cribriform morphology and/or intraductal carcinoma with adverse pathology was assessed by multivariable regression.RESULTS:
Of the 455 men who underwent prostatectomy 216 (47.5%) had biopsy identified with cribriform morphology and/or intraductal carcinoma. For cribriform morphology and/or intraductal carcinoma the sensitivity and specificity of biopsy was 56.5% and 87.2%, respectively. In men eligible for active surveillance sensitivity was 34.1% and specificity was 88.1%. Magnetic resonance imaging targeted biopsies did not improve sensitivity (53.5%). Cribriform morphology and/or intraductal carcinoma identified on prostatectomy correlated with adverse pathological findings. However, compared to cribriform morphology and/or intraductal carcinoma negative biopsies, biopsies identified with cribriform morphology and/or intraductal carcinoma were not independently associated with adverse pathology. This was likely due to biopsy low sensitivity.CONCLUSIONS:
In this cohort biopsy was not sensitive for detecting cribriform morphology and/or intraductal carcinoma and this was not improved by magnetic resonance imaging fusion. However, specificity was high, suggesting that when present on biopsy, cribriform morphology and/or intraductal carcinoma may be considered in treatment planning algorithms.Palavras-chave
