Hypofractionated Radiation Therapy or Conventional Radiation Therapy After Surgery in Treating Patients With Prostate Cancer
Study Details
Study Description
Brief Summary
This randomized phase III trial studies how well hypofractionated radiation therapy works compared to conventional radiation therapy after surgery in treating patients with prostate cancer. 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. Conventional radiation therapy uses high energy x-rays, gamma rays, neutrons, protons, or other sources to kill tumor cells and shrink tumors. It is not yet known whether giving hypofractionated radiation therapy or conventional radiation therapy after surgery may work better in treating patients with prostate cancer.

Detailed Description
PRIMARY OBJECTIVES:
- To demonstrate that hypofractionated post-prostatectomy radiotherapy (HYPORT) does not increase patient-reported gastrointestinal (GI) or genitourinary (GU) symptoms over conventionally fractionated post-prostatectomy (COPORT) at the 2-year time point.
SECONDARY OBJECTIVES:
-
To compare patient-reported GI symptoms using the Expanded Prostate Cancer Index Composite (EPIC)-26 at end of radiation therapy (RT) and 6, 12, 24, and 60 months from end of treatment.
-
To compare patient-reported GU symptoms using the EPIC-26 at end of RT and 6, 12, 24, and 60 months from end of treatment.
-
To compare the cost effectiveness based on the cost of radiotherapy and measured utilities for health outcomes using the EuroQol five dimensions questionnaire (EQ-5D).
-
To compare time to progression (TTP) where progression is defined as the first occurrence of biochemical failure (BF), local failure, regional failure, distant metastasis (DM), institution of new unplanned anticancer treatment, or death from prostate cancer (prostate cancer specific mortality [PCSM]).
-
To compare freedom from biochemical failure (FFBF) and TTP rates with an alternate prostate specific antigen (PSA) >= PSA nadir + 2 ng/mL definition of BF.
-
To compare local failure, regional failure, salvage therapy (i.e. institution of new unplanned anticancer treatment), DM, PCSM, and overall survival (OS) rates.
-
Assessment of adverse events. VIII. Paraffin-embedded tissue block, serum, plasma, whole blood, and urine for future translational research analyses for predictors of toxicity following hypofractionated or conventionally fractionated post-prostatectomy radiotherapy.
After completion of study treatment, patients are followed up every 6 months for 2 years and every year for 3 years and thereafter.

Outcome Measures
Primary Outcome Measures
- Change in Urinary Domain of the Expanded Prostate Cancer Index (EPIC) at Two Years [Baseline (randomization), 2 years]
The EPIC is a prostate cancer health-related quality of life (HRQOL) self-administered instrument measuring patient-reported urinary, bowel, sexual, and hormonal symptoms related to prostate cancer treatments. Response options for each item form a Likert scale with scores transformed linearly to a 0-100 scale. Domain scores are also on a 0-100 scale with higher scores representing better HRQOL. The urinary domain contains 12 items. Change from baseline is calculated by subtracting baseline from later score, with a positive change score indicating increased HRQOL.
- Change in Bowel Domain of the Expanded Prostate Cancer Index (EPIC) at Two Years [Baseline, 2 years]
The EPIC is a prostate cancer health-related quality of life (HRQOL) self-administered instrument measuring patient-reported urinary, bowel, sexual, and hormonal symptoms related to prostate cancer treatments. Response options for each item form a Likert scale with scores transformed linearly to a 0-100 scale. Domain scores are also on a 0-100 scale with higher scores representing better HRQOL. The bowel domain contains 14 items. Change from baseline is calculated by subtracting baseline from later score, with a positive change score indicating increased HRQOL.
Secondary Outcome Measures
- Change in Urinary Domain Score of the Expanded Prostate Cancer Index (EPIC) at End of Radiation Therapy (RT), 6 Months, 1 and 5 Years [Baseline, end of RT, then 6 months,1 and 5 years from the start of RT (5 year time point has not yet been reached). RT dates depend on timing and duration of androgen deprivation therapy (ADT) (optional) and RT.]

- Percentage of Participants With Biochemical Failure [From randomization to last follow-up. Maximum follow-up at time of analysis was 3.0 years.]
Biochemical failure was analyzed using two different definitions. The protocol definition of biochemical failure is a PSA measurement ≥ 0.4 ng/mL and rising (i.e. PSA ≥ 0.4 ng/mL followed by a value higher than the first by any amount) or followed by initiation of salvage hormones. The Phoenix definition of biochemical failure is a PSA measurement ≥ PSA nadir + 2 ng/mL where nadir is the lowest post-RT PSA value. Time to biochemical failure is defined as time from randomization to the date of first biochemical failure, last known follow-up (censored), or death without biochemical failure (competing risk). Biochemical failure rates are estimated using the cumulative incidence method. The protocol specifies that the distributions of failure times be compared between the arms, which is reported in the statistical analysis results. Two-year rates are provided.
- Percentage of Participants With Progression [From randomization to last follow-up. Maximum follow-up at time of analysis was 3.0 years. Two-year rates reported here. Follow-up schedule: end of RT, then 6, 12, 18, 24 months from start of RT, then yearly.]
Progression (failure) is defined as the first occurrence of biochemical failure, local failure, regional failure, distant failure, institution of new unplanned anticancer treatment, or death from prostate cancer. Time to progression is defined as time from randomization to the date of progression, last known follow-up (censored), or death without progression (competing risk). Progression rates are estimated using the cumulative incidence method. The protocol specifies that the distributions of failure times be compared between the arms, which is reported in the statistical analysis results. Two-year rates are provided.
- Percentage of Participants With Local-Regional Failure [From randomization to last follow-up. Maximum follow-up at time of analysis was 3.0 years. Two-year rates reported here. Follow-up schedule: end of RT, then 6, 12, 18, 24 months from start of RT, then yearly.]
Local-regional failure is defined as local or regional failure. Local failure is defined as the development of a new biopsy-proven mass in the prostate bed. Regional failure is defined as radiographic evidence (CT or MRI) of lymphadenopathy (lymph node size ≥ 1.0 cm in the short axis) in a patient without the diagnosis of a hematologic/lymphomatous disorder associated with adenopathy. Time to local-regional failure is defined as time from randomization to the date of first local-regional failure, last known follow-up (censored), or death without local-regional (competing risk). Local-regional failure rates are estimated using the cumulative incidence method. The protocol specifies that the distributions of failure times be compared between the arms, which is reported in the statistical analysis results. Two-year rates are provided.
- Percentage of Participants Receiving Salvage Therapy [From randomization to last follow-up. Maximum follow-up at time of analysis was 3.0 years. Two-year rates reported here. Follow-up schedule: end of RT, then 6, 12, 18, 24 months from start of RT, then yearly.]
Salvage therapy is defined as the initiation of new unplanned anticancer treatment. Time to salvage therapy initiation is defined as time from randomization to the date of first salvage therapy, last known follow-up (censored), or death without salvage therapy (competing risk). Salvage therapy rates are estimated using the cumulative incidence method. The protocol specifies that the distributions of salvage initiation times be compared between the arms, which is reported in the statistical analysis results. Two-year rates are provided.
- Percentage of Participants With Distant Metastasis [From randomization to last follow-up. Maximum follow-up at time of analysis was 3.0 years. Two-year rates reported here. Follow-up schedule: end of RT, then 6, 12, 18, 24 months from start of RT, then yearly.]
Distant metastasis (failure) is defined as radiographic evidence of hematogenous spread evaluated by bone scan, CT, or MRI. Time to distant metastasis is defined as time from randomization to the date of first distant metastasis, last known follow-up (censored), or death without local recurrence (competing risk). Distant metastasis rates are estimated using the cumulative incidence method. The protocol specifies that the distributions of failure times be compared between the arms, which is reported in the statistical analysis results. Two-year rates are provided.
- Percentage of Participants Who Died From Prostate Cancer (Prostate Cancer Specific Mortality) [From randomization to last follow-up. Maximum follow-up at time of analysis was 3.0 years. Two-year rates reported here. Follow-up schedule: end of RT, then 6, 12, 18, 24 months from start of RT, then yearly.]
Cause of death was centrally reviewed. Count and percentage at time of analysis are reported.
- Percent of Participants Alive (Overall Survival) [From randomization to last follow-up. Maximum follow-up at time of analysis was 3.0 years. Two-year rates reported here. Follow-up schedule: end of RT, then 6, 12, 18, 24 months from start of RT, then yearly.]
Overall survival time is defined as time from registration/randomization to the date of death (failure) from any cause or last known follow-up (censored). Overall survival rates are estimated by the Kaplan-Meier method. The protocol specifies that the distributions of failure times be compared between the arms, which is reported in the statistical analysis results. 2-year rates are provided.
- Number of Participants With Grade 3+ Adverse Events [From randomization to last follow-up. Maximum follow-up at time of analysis was 3.0 years. Follow-up schedule: end of RT, then 6, 12, 18, 24 months from start of RT, then yearly.]
Common Terminology Criteria for Adverse Events (CTCAE) version 4 grades adverse event severity from 1=mild to 5=death. Summary data is provided in this outcome measure; see Adverse Events Module for specific adverse event data. Counts of participants with any grade 3 or higher adverse event, any grade 3 or higher gastrointestinal adverse events, and any grade 3 or higher genitourinary adverse events are reported. Adverse events of any attribution are included.

Outcome Measures
Title | Change in Urinary Domain of the Expanded Prostate Cancer Index (EPIC) at Two Years |
---|---|
Description | The EPIC is a prostate cancer health-related quality of life (HRQOL) self-administered instrument measuring patient-reported urinary, bowel, sexual, and hormonal symptoms related to prostate cancer treatments. Response options for each item form a Likert scale with scores transformed linearly to a 0-100 scale. Domain scores are also on a 0-100 scale with higher scores representing better HRQOL. The urinary domain contains 12 items. Change from baseline is calculated by subtracting baseline from later score, with a positive change score indicating increased HRQOL. |

Comments | Null hypothesis (H0): mean change score of HYPORT (∆2) is worse than that of COPORT (∆1), specifically ∆2 - ∆1 < -5. Alternative hypothesis (HA): ∆2 is not worse than ∆1, specifically ∆2 - ∆1 ≥ -5. The study sample size is based on 90% power for this endpoint and 91% power for the bowel endpoint (resulting in 81.9% statistical power to reject the null hypothesis for both endpoints) and a one-sided alpha=0.025 with an overall type I error of 0.05 with a Bonferroni adjustment. | |

Response options for each item form a Likert scale with scores transformed linearly to a 0-100 scale. Domain scores are also on a 0-100 scale with higher scores representing better HRQOL. The urinary domain contains 12 items. Change from baseline is calculated by subtracting baseline from later score, with a positive change score indicating increased HRQOL. |
Time Frame | Baseline, end of RT, then 6 months,1 and 5 years from the start of RT (5 year time point has not yet been reached). RT dates depend on timing and duration of androgen deprivation therapy (ADT) (optional) and RT. |

Title | Percentage of Participants With Biochemical Failure |
---|---|
Description | Biochemical failure was analyzed using two different definitions. The protocol definition of biochemical failure is a PSA measurement ≥ 0.4 ng/mL and rising (i.e. PSA ≥ 0.4 ng/mL followed by a value higher than the first by any amount) or followed by initiation of salvage hormones. The Phoenix definition of biochemical failure is a PSA measurement ≥ PSA nadir + 2 ng/mL where nadir is the lowest post-RT PSA value. Time to biochemical failure is defined as time from randomization to the date of first biochemical failure, last known follow-up (censored), or death without biochemical failure (competing risk). Biochemical failure rates are estimated using the cumulative incidence method. The protocol specifies that the distributions of failure times be compared between the arms, which is reported in the statistical analysis results. Two-year rates are provided. |
Time Frame | From randomization to last follow-up. Maximum follow-up at time of analysis was 3.0 years. |
