Abstract:
Objective:To observe the clinicopathologic features and prognosis of prostate cancer (PCa) in young men.
Methods:Twenty-eight early onset (≤55 years) patients with PCa pathologically confirmed in the Peking University Third Hospital and Peking University Shougang Hospital from January 1st 2000 to August 31st 2016 were collected. There were 18 radical prostatectomy (RP) cases and 10 transrectal prostatic biopsy cases. Contemporaneously, 445 elderly (>55 years) patients were collected, of which 385 had detailed pathological information, were chosen as control group. The mean age of young group was 51 years (29-55 years). Follow-up data for 22 cases were available (1-110 months). The correlation of the clinicopathological features and prognosis were analyzed retrospectively.
Results:Presurgical prostatic specific antigen (PSA) level was abnormal in young patients, with 18 cases (64.3%) had elevated fPSA level, 26 (92.9%) had increased tPSA level, and 26 (92.9%) had decreased fPSA/tPSA ratio. Gleason score (GS) was 8 in 10.7% (3/28) of cases, and 9 in 42.9% (12/28) of cases. Of the 18 patients with RP, 17 (94.4%) had pT stage ≥pT2c. PSA level (P=0.006) and GS (P=0.001) were positively correlated with pT stage. Family history of PCa in 1st degree relatives was found in 9.1% of the cases. During follow-up, 2 patients died of PCa, 7 patients showed progression within 24 months. There were no significant differences in PSA level and GS between young patients and elderly patients, while the former group was more likely to have incontinence (P=0.023), higher PSA levels (P=0.001), and lower overall survival (P=0.049). Only postsurgical PSA level was found to be negatively associated with overall survival (P=0.030) and cancer specific survival (P=0.021) in young patients.
Conclusions:Presurgical PSA level and GS are positively correlated with pT stage of early onset PCa. Compared with elderly patients, young patients are more likely to have incontinence, higher postsurgical PSA level, and lower overall survival. Among all the parameters, only postsurgical PSA level shows an adverse impact on prognosis of early onset PCa. Young patients, especially those with family history, may benefit from studies on the susceptibility loci and phenotype of PCa.
