This trial is active, not recruiting.
|Sponsor||Swiss Group for Clinical Cancer Research|
|Start date||January 2011|
|End date||July 2016|
|Trial size||350 participants|
|Trial identifier||NCT01272050, CDR0000691926, EU-21088, SAKK 09/10, SWS-SAKK-09/10|
RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. It is not yet known which radiation therapy regimen is more effective in treating patients with relapsed prostate cancer.
PURPOSE: This randomized phase III trial is studying the side effects of radiation therapy and comparing two radiation therapy regimens in treating patients with relapsed prostate cancer after surgery.

|Official title||Dose Intensified Salvage Radiotherapy in Biochemically Relapsed Prostate Cancer Without Macroscopic Disease. A Randomized Phase III Trial.|
|Description||OBJECTIVES: - To determine the tumor control in patients with biochemically relapsed prostate cancer without macroscopic disease treated with dose-intensive salvage radiotherapy. - To determine the toxicity in these patients. - To determine the quality of life of these patients. OUTLINE: This is a multicenter study. Patients are stratified according to Gleason score (≥ 8 vs 7 vs ≤ 6), pathological tumor classification (pT3b vs others), lymphadenectomy performed (yes [pN0] vs no [cN0]), persistent PSA after prostatectomy (detectable [≥ 0.1 ng/mL] vs undetectable [< 0.1 ng/mL]), PSA at randomization (> 0.5 ng/mL vs ≤ 0.5 ng/mL), participating center, and radiotherapy technique (3-dimensional conformal radiation therapy [3D-CRT] vs intensity-modulated radiation therapy [IMRT]/rotational techniques). Patient are randomized to 1 of 2 treatment arms. - Arm A: Beginning at least 12 weeks after surgery, patients undergo radiotherapy* once a day, 5 days a week, for 6.4 weeks for a total dose of 64 Gy (in 32 fractions of 2 Gy over 6.4 weeks). - Arm B: Patients undergo radiotherapy* once a day, 5 days a week, for 7 weeks for a total dose of 70 Gy (in 35 fractions of 2 Gy over 7 weeks). NOTE: *3-dimensional conformal radiation therapy, rotational techniques such as Tomotherapy®, Rapidarc®, or intensity-modulated arc technique and volumetric-modulated arc therapy are all eligible. Patients complete quality-of-life questionnaires at baseline and at 3, 12, 24, 36, 48, and 60 months after completing study therapy. After completion of study treatment, patients are followed every 6 months for 3 years and then every 12 months for up to 10 years.|
