We had six cases of patients who were treated with long-term testosterone replacement therapy (TRT) after high dose-rate (HDR) brachytherapy and androgen deprivation therapy for high-risk prostate cancer. All patients were given testosterone enanthate by intramuscular injection every 3 to 4 weeks. Blood biochemistry including prostate specific antigen (PSA) level was evaluated every 3 to 6 months after TRT, and radiological imaging was performed every 12 months. All patients had slight increases in PSA within the normal range and not indicative of biochemical recurrence. A sudden increase in PSA was observed in one patient, but it finally decreased. Aging male symptoms scale and various metabolic factors were improved by TRT in all of cases. Although adverse events included polycythemia in one patient, no patients experienced disease recurrence or progression during TRT. Our results suggest TRT for high risk-patients with HDR brachytherapy for prostate cancer may be beneficial and safe.

The International Prostate Symptom Score (IPSS) is often used as an interview sheet for assessing lower urinary tract symptoms (LUTS) at the time of prostate-specific antigen (PSA) testing during population-based screening for prostate cancer. However, the relationship between prostate cancer detection and LUTS status remains controversial. To elucidate this relationship, the cumulative probability of prostate cancer detection using IPSS in biopsy samples from patients categorized by serum PSA levels was investigated. The clinical characteristics of prostate cancer detected using IPSS during screening were also investigated. A total of 1,739 men aged 54-75 years with elevated serum PSA levels who completed the IPSS questionnaire during the initial population screening in Kanazawa City, Japan and underwent systematic transrectal ultrasonography-guided prostate biopsy between 2000 and 2013 were enrolled in the present study. Of the 1,739 men, 544 (31.3%) were diagnosed with prostate cancer during the observation period. The probability of cancer detection at 3 years in the entire study population was 27.4% and 32.7% for men with $IPSS{\leq}7$ and those with $IPSS{\geq}8$, respectively; there was no statistically significant difference between groups. In men with serum PSA levels of 6.1 to 12.0ng/mL at initial screening, the probability of cancer detection was significantly higher in men with $IPSS{\leq}7$ than in those with $IPSS{\geq}8$. There were no significant differences in clinical characteristics between groups of patients stratified by IPSS. These findings indicate that the use of IPSS for LUTS status evaluation may be useful for prostate cancer detection in the limited range of serum PSA levels.
