About this study

The number of metastases may reflect the biological aggressiveness of the tumor and may determine the possibility of performing potential curative interventions such as surgery or high-dose targeted radiotherapy (RT). Until a few years ago, the treatment of choice for metastatic prostate cancer was androgen deprivation (TDA). This treatment was carried out as palliative care in order to postpone the progression of the disease or reduce symptoms. Patients with prostate cancer with a limited number of metastases, similarly to patients suffering from other solid tumors, can be considered as patients with disease that has limited capacity to cause further secondary effects. In this scenario, the primary treatment in patients with carcinoma localized prostate, is characterized by radical prostatectomy, followed by measurement of prostate specific antigen (PSA) during follow-up. After primary prostatectomy, PSA values > 0.2 ng/mL are indicative of disease recurrence, but it is not possible to determine whether the recurrence is local or distant. Furthermore, imaging modalities, such as bone scanning and computed tomography (CT), do not have sufficient sensitivity to detect the presence of metastatic disease in patients with low PSA levels. Positron emission tomography/CT with 11C-choline is able to detect local or distant metastases with a sensitivity and specificity greater than 85% in patients with biochemical disease recurrence. 11C-Choline PET/CT can be a valid tool both for diagnosis and for guiding radiotherapy treatments in these patients for whom it is not possible to obtain a definitive diagnosis with conventional diagnostic procedures. There are currently few studies that have described the use of 11C-choline PET/CT to guide treatment for bone metastases; the limitations of these studies concern the small number of patients and the short follow-up. The aim of this retrospective observational study was to evaluate the efficacy of 11C-choline PET/CT as a guide to the treatment of helical tomotherapy for an innovative therapeutic approach in bone metastases in a population of patients affected by prostate cancer with a limited number of metastasis.

Questions about this trial

What is this clinical trial studying?

An observational study of Prostate Cancer, run by IRCCS San Raffaele at 1 site 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 2 inclusion and 1 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: finished, as of the sponsor's last update on 6 Mar 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

11C-choline PET/CT to the treatment of patients with prostate cancer with a limited number of metastasis. (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 6 Mar 2024.
