Long-Term Outcomes After High-Dose Postprostatectomy Salvage Radiation Treatment

Salvage RT provides effective long-term biochemical control and freedom from metastasis in selected patients presenting with detectable PSA after prostatectomy. Androgen-deprivation therapy was associated with improvement in biochemical progression-free survival. Clinical local failures were rare but occurred most commonly in patients with greater burden of disease at time of SRT as reflected by either radiographic imaging or a greater PSA level. Salvage radiation doses ≥70 Gy may ultimately be most beneficial in these patients, but this needs to be further studied.
