About this study

Official title: Pre-operative Plasma Concentrations of Choline and Its Metabolites in People With Prostate Cancer Compared to Those With Benign Hyperplasia

The aim of this study was to investigate plasma concentrations of one-carbon metabolites and phospholipid classes in participants with primary prostate cancer and those with benign hyperplasia. Moreover, the metabolites were studied in relation to tumor grade and age.

Read the detailed description

This observational study recruited participants with primary prostate cancer (cases) and those with benign hyperplasia (controls) before the surgery. Data on the outcomes of the surgery including the results of the biopsy investigation were collected. Blood samples were collected before the surgery in context of routine blood investigations. Blood plasma samples collected on ethylenediaminetetraacetic acid (EDTA) were used to measure concentrations of free choline, betaine, dimethylglycine, folate forms, S-adenosylhomocysteine, S-adenosylmethionine, homocysteine, cystathionine, and methylmalonic acid (MMA). Data on serum concentrations of prostate specific antigen (PSA) and the tumor grade and classification (Gleason Score system) were collected. The associations between the plasma concentrations of the metabolites and PSA or the Gleason score were studied. The concentrations of the metabolic markers were compared between the cases and the controls according to the age of the participants.

    Measured: through study completion, on average 1 year

Secondary outcomes (6)
  1. Plasma and whole blood folate forms

    Concentrations measured in plasma with liquid chromatography tandem mass spectrometry

    Measured: through study completion, on average 1 year

  2. Plasma phospholipids

    Concentrations measured in plasma with liquid chromatography tandem mass spectrometry after extraction

    Measured: through study completion, on average 1 year

  3. Plasma S-adenosylmethionine concentrations

    Concentrations measured in plasma with liquid chromatography tandem mass spectrometry

    Measured: through study completion, on average 1 year

  4. Plasma betaine concentrations

Questions about this trial

What is this clinical trial studying?

An observational study of Primary Prostate Urothelial Cancer and Benign Prostatic Hyperplasia, run by Universität des Saarlandes at 1 site in Germany.

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 3 inclusion and 6 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 25 Apr 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 Germany. 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?

Plasma choline concentrations (time frame: through study completion, on average 1 year). The study lists 2 primary outcomes in all. 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 NCT06380062, which also lists 2 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 Apr 2024.
