Material and methods: We evaluated 367 patients who underwent RP between 2009 and 2016, with pT2 disease in the final pathological evaluation. We assessed differences in rates of biochemical recurrence (BCR), metastasis and mortality between T2 substages (pT2a/b vs pT2c).
Results: Fifty-three (14.4%) patients presented pT2a/b disease and 314 (85.6%) pT2c disease. The mean follow-up time was 4.9 ± 2.6 years. Grade group scores (p = 0.1) and prostate specific antigen (PSA) (p = 0.2) did not differed between pT2 substages. The rate of BCR in pT2a/b and pT2c patients was 11.3% and 18.2%, respectively (p = 0.2). Five (9.4%) patients with pT2a/b and 45 (14.3%) with pT2c substage underwent salvage radiotherapy (p = 0.3). The rate of positive surgical margins did not differ between groups (p = 0.2). Seven (2.2%) patients with pT2c had lymph nodes or distant metastases. The overall survival was 92.5% and 93.6% in pT2a/b and pT2c, respectively (p = 0.2).
Conclusion: Our results are in accordance with the changes introduced in the 8th edition of the AJCC staging system in which the pT2 subclassification was eliminated.
