Study type | Interventional |
This phase III trial studies how well hypofractionated radiation therapy works compared to the conventional one in treating patients with prostate cancer. Radiation therapy uses high energy beams to kill tumor cells and shrink tumors. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more tumor cells and have fewer side effects.

Eligibility | Inclusion Criteria: - Men age 18 or older - Patient has diagnosis of pathologically confirmed prostate cancer, treated with radical prostatectomy. Any type of radical prostatectomy will be permitted, including retropubic, perineal, laparoscopic, or robotically assisted - Patient has pathologic T2-T3M0 stage. Patients can have 5 or less metastatic pelvic lymph nodes confirmed by pathology - For patients radiated in the post-operative salvage setting: pathology can demonstrate any of the following features but not required, positive margin, extracapsular extension, or seminal vesicle involvement with detectable prostate-specific antigen (PSA) of >= 0.1. PSA >= 0.1 after radical prostatectomy: most recent PSA value within 12 months of registration and prior to initiating any androgen deprivation therapy (ADT) - Patient diagnosed with Gleason score of 6-10 - Eastern Cooperative Oncology Group (ECOG) performance 0-2 - Patients may receive 6 months and up to 24 months of androgen deprivation therapy. Patients may have received androgen deprivation therapy up to 12 months prior to postoperative radiotherapy - If the patient has a prior history of any cancer other than prostate cancer, he must have completed treatment within 1 year of study registration and the patient must have no evidence of disease of this prior non-prostate cancer Exclusion Criteria: - Prior radiation therapy to prostate/seminal vesicle fossa or postoperative region - Neoadjuvant chemotherapy before or after prostatectomy - History of lupus, scleroderma, or calcinosis, Raynaud's phenomenon, esophageal dysmotility, sclerodactyly, and telangiectasia (CREST) syndrome - History of severe active co-morbidity or uncontrolled diabetes - Unstable angina and/or congestive heart failure requiring hospitalization within the last 6 months - Transmural myocardial infarction within the last 6 months - Severe hepatic disease, defined as a diagnosis of Child-Pugh class B or C hepatic disease - End-stage renal disease (i.e., on dialysis or dialysis has been recommended) |

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Incidence of >= grade 2 gastrointestinal (GI) or genitourinary (GU) toxicity | Will be denoted as Tc and Te for conventional and hypo-fractionated arm respectively. | At 2 years | |
Secondary | Local control | Up to 5 years | ||
Secondary | Loco-regional control | Up to 5 years | ||
Secondary | Distant metastases | Up to 5 years | ||
Secondary | Biochemical progression-free survival | Will be analyzed using the Kaplan-Meier method. Log-rank test will be used to assess the differences in time-to-event outcomes between the two groups. Cox proportional hazards model will be fit to compare the two arms while accounting for other patient characteristics. | Up to 5 years | |
Secondary | Prostate-cancer specific survival (PCSS) | Will be analyzed using the Kaplan-Meier method. Log-rank test will be used to assess the differences in time-to-event outcomes between the two groups. Cox proportional hazards model will be fit to compare the two arms while accounting for other patient characteristics. | Up to 5 years | |
Secondary | Time to salvage therapy | Will be analyzed using the Kaplan-Meier method. Log-rank test will be used to assess the differences in time-to-event outcomes between the two groups. Cox proportional hazards model will be fit to compare the two arms while accounting for other patient characteristics. | Up to 5 years | |
Secondary | Biochemical failure (FFBF) | Up to 5 years | ||
Secondary | Time to progression (TTP) | Will be defined as post prostatectomy nadir + 2 ng/mL in both treatment arms. Will be analyzed using the Kaplan-Meier method. Log-rank test will be used to assess the differences in time-to-event outcomes between the two groups. Cox proportional hazards model will be fit to compare the two arms while accounting for other patient characteristics. | Up to 5 years | |
Secondary | Patient reported quality of life outcomes | Will evaluate patient reported quality of life outcomes with hypo-fractionated compared to standard fractionated postoperative radiotherapy using validated surveys (Expanded Prostate Cancer Index Composite [EPIC]-26, Short Form [SF]-12) and use of erectile dysfunction medications/devices. Will be summarized using descriptive statistics by treatment arm and will be compared using two sample t-test or Wilcoxon rank-sum test as appropriate. | Up to 5 years | |
Secondary | Patient reported GU symptoms | Will be assessed by Common Terminology Criteria for Adverse Events (CTCAE) version 5. Will be compared to quality of life reports with EPIC-26, SF-12, EQ-5D survey. Quality of life (QOL) data will be summarized using descriptive statistics by treatment arm and will be compared using two-sample t-test or Wilcoxon rank-sum test as appropriate. The generalized estimating equations (GEE) model will be fit to assess the change of GU or GI symptoms over time as well as treatment effect. | At end of radiation therapy (RT), 6, 12, 24 and up to 60 months from the end of RT | |
Secondary | Patient reported GI symptoms | Will be assessed by CTCAE version 5. Will be compared to quality of life reports with EPIC-26, SF-12, EQ-5D survey. QOL data will be summarized using descriptive statistics by treatment arm and will be compared using two-sample t-test or Wilcoxon rank-sum test as appropriate. The GEE model will be fit to assess the change of GU or GI symptoms over time as well as treatment effect. | At end of RT, 6, 12, 24, and up to 60 months from the end of RT | |
Secondary | Health economics | Will report health economics with cost and time based driven activity (TDABC) in delivering shorter hypofractionated courses of radiotherapy compared to standard course (indirect and direct cost). Will be summarized using descriptive statistics by treatment arm and will be compared using two sample t-test or Wilcoxon rank-sum test as appropriate. | Up to 5 years |
