Abstract
OBJECTIVE: Among western males, prostate cancer is the most frequent oncological disease. Since the widespread of PSA, diagnoses in younger adults is increasing. The aim of this study is to analyze pathological features and biochemical recurrence event in patients ≤55 years who underwent robotic radical prostatectomy (RRP) surgery.
MATERIAL AND METHODS: A study with a cohort of 510 patients operated between November 2012 and February 2017 in a tertiary centre is provided. A total of 460 are included in the analysis. Variables include PSA, biopsy Gleason score, prostate weight, final specimen Gleason score, pT and surgical margins. Biochemical recurrences during the follow-up are obtained. Statistical analysis with Chi2, Student's t test, Kaplan-Meier and log-rank (SPSS24.0) comparing the ≤55 years patients with older age group is performed.
RESULTS: 8.3% (38) of the patients were ≤55 years. The mean PSA among the younger group was 8.54ng/ml while in the older was 8.18ng/ml (p=0.13). The biopsy Gleason scores showed similar distribution in both age groups. 52.6% (20) of the young group presented an upgrading in the final Gleason, vs 49.1% (207) among the elderly (p=0.79). The average prost at eweight was higher among elderly patients (54.29g vs.40.50g P=0.001). 84.2% (32) of prostate cancers in young group corresponded to pT2 stages compared to 81.3% (343) in the elder (p=0.66). The presence of positive surgical margins was similar in both groups. The mean follow-up time was 45 months regardless of age. In 21.1% (8) of the young group, biochemical recurrence was detected compared to 17.1% (72) among the elderly (p=0.53). There were no differences in the biochemical recurrence-free survival recorded in both groups (p=0.53).
CONCLUSION: In our study population, patients  ≤55 years treated with RRP did not present differences in the pathologic features of prostate cancer or in biochemical recurrence rates in comparison to the group of older patients.
