About this study

Official title: Myeloid-derived Suppressor Cells in Colorectal Cancer: Influence on Postoperative Complications and Neoadjuvant Treatment

The aim of the study is to evaluate whether the preoperative level of myeloid-derived suppressor cells is associated with postoperative complications classified by Clavien-Dindo categories. Levels of all MDSC, polymorphonuclear MDSC (PMNMDSC), monocytic MDSC (MMDSC), early-stage MDSC (EMDSC) and monocytic to polymorphonuclear MDSC ratio (M/PMN MDCS) were established and compared in patients with postoperative complications, severe postoperative complications (>= IIIA according to Clavien-Dindo) and severe septic complications.

Read the detailed description

Levels of all MDSC, polymorphonuclear MDSC (PMNMDSC), monocytic MDSC (MMDSC), early-stage MDSC (EMDSC) and monocytic to polymorphonuclear MDSC ratio (M/PMN MDCS) were established and compared in patients with and without postoperative complications. Then subgroup analysis was performed to compare levels of MDSC in patients with severe postoperative complications (>= IIIA according to Clavien-Dindo) and those without severe complications. Another subgroup analysis will be performed for patients with severe septic complications that are defined as severe complications with accompanying infection. Levels of MDSC will be compared by means of U Mann Whitney test as their distribution is not normal. After above mentioned analyses it will be possible to evaluate the role of MDSC in patients with colorectal cancer in terms of postoperative complications. Additional analyse will be performed to compare levels of MDSC in patients who underwent neoadjuvant treatment (radiotherapy or chemoradiotherapy).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Level of MDSC in patients with postoperative complications

    Measured: 30 days

  2. Level of MDSC in patients with severe septic postoperative complications

    Level of all MDSC, PNMMDSC, MMDSC, EMDSC and M/PMNMDSC ratio in patients with severe postoperative complications (Clavien-Dindo>= IIIA) with infection

    Measured: 30 days

  3. Level of MDSC in patients after neoadjuvant therapy

    Level of all MDSC, PNMMDSC, MMDSC, EMDSC and M/PMNMDSC ratio in patients after neoadjuvant treatment

    Measured: 1 day before surgery

  4. Level of MDSC in patients with T2-T4 tumours after neoadjuvant treatment

    Level of all MDSC, PNMMDSC, MMDSC, EMDSC and M/PMNMDSC ratio in patients with tumours T2-T4 after neoadjuvant treatment

Questions about this trial

What is this clinical trial studying?

An observational study of Colorectal Cancer and Suppression, run by Jagiellonian University at 1 site in Poland.

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 4 inclusion and 4 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 7 Jul 2022. 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 Poland. 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?

Level of MDSC in patients with postoperative complications (time frame: 30 days). 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 NCT04943419, which also lists 1 linked publication.

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 7 Jul 2022.
