전립선비대증 환자에서 Dutasteride 치료 후 혈 중 Prostate-specific antigen 치의 변화 = The Effect of Dutasteride on Serum Prostate-specific Antigen (PSA) in Patients with BenignProstate Hypertrophy

다국어 초록 (Multilingual Abstract)

Purpose: 5α reductase, dutasteride, has widely used to treat enlarged prostate (BPH). By suppressing
the conversion of testosterone to dihydrotestosterone it decreases serum prostate-specific antigen
(PSA) which is very important screening marker for prostate cancer. We evaluate the early serum
PSA changes after dutasteride treatment to Korean BPH patients.
Materials and Methods: A total 159 men with a clinical diagnosis of BPH and no evidence of
prostate cancer were enrolled. They were treated with dutasteride 0.5mg daily for 12 months. Serum
PSA was evaluated at 2, 6, and 12 months after the medication.
Result: Dutasteride statistically significantly reduced serum PSA to 0.70±0.52, 0.64±0.35, and
0.59±0.49 from baseline level at 2, 6, and 12 months after the medication, respectively. However,
there was no statistical significance among the three groups in serum PSA changes after dutasteride.
There were statistically significant correlations between a high pre-treatment serum PSA level and
a large reduction of follow-up PSA levels at 2, 6, and 12 months after dutasteride treatment.
Conclusions: The reduction of serum PSA is variable in patients to patients at 2, 6, and 12 months
after dutasteride treatment. The patient with high initial serum PSA revealed a large reduction
of serum PSA level after treatment. The traditional concept that follow-up serum PSA level should
be doubled for prostate cancer screening may overestimate real serum PSA level within 12 months
in Korean men receiving 5α reductase inhibitors. (J Korean Continence Soc 2008;12:42-47)
