Indication for permanent interstitial brachytherapy (PIB) can be limited by prostate volume, commonly decreased using neoadjuvant hormonal therapy. Volume changes and initial clinical results focusing on patients treated with prostatic artery embolization (PAE) were evaluated in this study.A group of 102 consecutive patients were treated with permanent interstitial brachytherapy (PIB), 13 patients received a neoadjuvant PAE (median 12 weeks before PIB) in case of large prostate volume60 cm³, and moderate to severe urinary problems.Patients after PAE were treated with significantly larger prostate volumes (52 ± 11 cm³ vs. 39 ± 11 cm³; p0.01; 66 ± 17 cm³ before PAE), but larger volume reductions to 44 ± 10 cm³ versus 35 ± 10 cm³ was found at day 30 (p0.05). International Prostate Symptom Score (IPSS) decreased significantly from 13 ± 5 before PAE to 7 ± 4 after PAE; p0.01. Initial PSA and first PSA after PIB were similar for patients with versus without PAE (5.9 ± 2.9 ng/mL vs. 6.2 ± 2.8 ng/mL and 1.5 ± 0.8 ng/mL vs. 1.9 ± 1.5 ng/mL). However, PSA 12 months after PIB was significantly lower after PAE (0.4 ± 0.3 ng/mL vs. 0.8 ± 0.6 ng/mL; p = 0.03). Four patients without prior PAE needed an intervention after urinary retention - transurethral resection of the prostate (TURP) in three cases and PAE in a single case. Urinary incontinence resulted in two cases after TURP.PAE could be successfully applied to decrease prostate volume and reduce urinary symptoms before PIB or as a treatment for urinary retention after PIB. A significantly lower PSA is promising for improved long-term cancer control. |
