About this study
The use of hypofractionated radiotherapy for prostate cancer has matured to a point that in current guidelines extremely hypofractionated image-guided IMRT regimens (6 Gy per fraction or greater) can be considered an alternative to conventionally fractionated regimens at clinics with appropriate technology, physics and clinical expertise. The delivery of fewer and larger fractions with hypofractionation compared to conventional radiotherapy might effectively improve the therapeutic ratio while maintaining isoeffective tumour doses, thus, shortening overall treatment time. In the present study, patients will undergo postoperative image-guided SBRT by means of volumetric intensity-modulated arc radiotherapy (IGRT-VMAT) with state-of-the-art treatment-planning and quality assurance procedures. Normal tissue sparing and delivery accuracy are accomplished by the use of devices that ensure stability and beam location reproducibility. The primary endpoint is to evaluate the cumulative incidence of treatment related toxicities and adverse events in the acute (< 90 days from the end of treatment) and late (> 90 days) setting.
Read the detailed description
In this observational prospective trial eligible patients are those with adverse pathological features or rising PSA after radical prostatectomy proposed for receiving 31 Gy in 5 sessions each of 6.2 Gy to the prostatic bed delivered in one week, and up to 32.5 Gy in 5 sessions each of 6.5 Gy delivered in one week, respectively, in case of clinical relapse.
Patients will be treated by means of image guided volumetric modulated radiotherapy (IGRT-VMAT). A real time non-ionizing target monitoring might be used to account for intra-fractional errors, if deemed appropriate. Whether the dose constraints to the normal tissues are at risk, these will be prioritised over the prescription dose to the target. The primary endpoint of the trial is to assess the treatment related toxicity measured by the CTCAE v5.0. Secondary endpoints are quality of life in different domains (sexual, rectal , urinary) and biochemical outcome.
Patients will be followed at approximately one month, then every 3 months for the first 12 months and every 6 months thereafter. Quality of Life will be prospectively evaluated through validated tools (ECOG, EPIC, IIEF-5, ICIQ-SF) at various timepoints. Percentage or total mean score will be reported according to the questionnaires, whether they grade values in a scale or use descriptive statistics. Kaplan-Meier curve analysis of biochemical relapse free survival (b-RFS) at 2 and 5-year bRFS for all patients will be estimated.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The use of hypofractionated radiotherapy for prostate cancer has matured to a point that in current guidelines extremely hypofractionated image-guided IMRT regimens (6 Gy per fraction or greater) can be considered an alternative to conventionally fractionated regimens at clinics with appropriate technology, physics and clinical expertise. The delivery of fewer and larger fractions with hypofractionation compared to conventional radiotherapy might effectively improve the therapeutic ratio while maintaining isoeffective tumour doses, thus, shortening overall treatment time. In the present study, patients will undergo postoperative image-guided SBRT by means of volumetric intensity-modulated arc radiotherapy (IGRT-VMAT) with state-of-the-art treatment-planning and quality assurance procedures. Normal tissue sparing and delivery accuracy are accomplished by the use of devices that ensure stability and beam location reproducibility. The primary endpoint is to evaluate the cumulative incidence of treatment related toxicities and adverse events in the acute (< 90 days from the end of treatment) and late (> 90 days) setting.
Detailed description
In this observational prospective trial eligible patients are those with adverse pathological features or rising PSA after radical prostatectomy proposed for receiving 31 Gy in 5 sessions each of 6.2 Gy to the prostatic bed delivered in one week, and up to 32.5 Gy in 5 sessions each of 6.5 Gy delivered in one week, respectively, in case of clinical relapse.

Questions about this trial
What is this clinical trial studying?
An observational study of Radiation Toxicity, run by University of Milano Bicocca at 2 sites in Italy.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 8 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 25 Oct 2022. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites in Italy. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Stefano Arcangeli, MD (+39-0392333663, stefano.arcangeli@unimib.it), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Number of participants with treatment-related adverse events as assessed by CTCAE v.5.0 (time frame: 60 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04831970, which also lists 10 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Oct 2022; AzTrials last refreshed its copy on 27 Oct 2026.
