Abstract

We previously reported that reactive stromal grading in radical prostatectomies is a predictor of recurrence and that reactive stromal grading 0 and 3 are associated with lower biochemical recurrence-free survival rates than reactive stromal grading 1 and 2. We explored the prognostic significance of reactive stromal grading in preoperative needle biopsies. At Baylor College of Medicine, 224 cases of prostatic carcinoma were diagnosed by needle biopsy. Reactive stromal grading was evaluated on hematoxylin-eosin (H&E)-stained sections on the basis of previously described criteria: grade 0, with 0% to 5% reactive stroma; grade 1, 6% to 15%; grade 2, 16% to 50%; grade 3, 51% to 100%, or at least a 1:1 ratio between glands and stroma. Kaplan-Meier and Cox proportional hazard analyses were used. Reactive stromal grading distribution was as follows: reactive stromal grading 0, 1 case (0.5%); reactive stromal grading 1, 149 cases (66.5%); reactive stromal grading 2, 59 cases (26.3%); reactive stromal grading 3, 15 cases (6.7%). Reactive stromal grading in biopsies was correlated with adverse clinicopathologic parameters in the prostatectomy. Patients with reactive stromal grading 1 and 2 had better survival than those with 0 and 3 (P = .0034). Reactive stromal grading was an independent predictor of recurrence (hazard ratio = 1.953; P = .0174). Reactive stromal grading is independent of Gleason 4 + 3 and 3 + 4 in patients with a Gleason score of 7. Quantitation of reactive stroma and recognition of the stromogenic carcinoma in H&E-stained biopsies is useful to predict biochemical recurrence in prostate carcinoma patients independent of Gleason grade and prostate-specific antigen.
