Özet

Background & objectives Gleason scores guide clinical management in prostate adenocarcinoma. Cribriform glands are linked to poorer outcomes. Our study aims to assess the prognostic role of invasive cribriform gland size and percentage in low-intermediate risk group adenocarcinomas. Methods Our study enrolled 177 male patients with Grade Group 2 and 3 prostate adenocarcinoma. All cases were re-evaluated and recorded clinical and pathological data. The largest invasive cribriform gland was identified and its diameter measured. P63 was used as a basal marker for all cases Results The mean age of the patients was 67.8 years. Lymph node metastasis was not detected in cases without cribriform pattern, whereas it was noted in 22.5% of cases with cribriform pattern (p=0.014). The mean percentage of cribriform glands and the mean largest invasive cribriform gland size were significantly higher in cases with lymph node metastasis compared to cases without lymph node metastasis (34.3% - 2.98 mm vs. 17.5% - 1.98 mm, respectively; p<0.001 and p=0.003, respectively). Biochemical recurrence-free survival was significantly lower in cases with a maximum invasive cribriform gland diameter of >0.5 mm (p<0.001) and in cases with a cribriform pattern percentage of >10% (p<0.001). Conclusion Mean cribriform gland sizes and percentages were significantly associated with more advanced pT status, a higher rate of extraprostatic extension, lymph node metastasis, biochemical recurrence, higher preoperative PSA values, surgical margin positivity, and lower biochemical recurrence-free survival. Our findings suggest that a more aggressive clinical approach may be needed in grade group 2 and 3 cases with invasive cribriform glands larger than 0.5 mm and a cribriform gland percentage of >10% in prostate needle biopsies.
