Trial summary

Multiple lines of evidence have shown that perioperative opioids requirement was associated with poor outcomes in cancer patients, including increased cancer progression and metastases and reduced survival in patients with lung, breast, prostate, and bladder cancer. Read more about this study

About this study

Official title: Influence of Peri-operative Opioids on Circulating Tumor Cells in Patients Undergoing Robot-Assisted Laparoscopic Radical Cystectomy

Multiple lines of evidence have shown that perioperative opioids requirement was associated with poor outcomes in cancer patients, including increased cancer progression and metastases and reduced survival in patients with lung, breast, prostate, and bladder cancer. Circulating tumor cells (CTCs) have been validated as prognostic biomarkers of a number of cancers. The aim of this study is to investigate the effects of perioperative opioids on the number of CTCs in patients receiving robot-assisted laparoscopic radical cystectomy. The difference of the amounts of perioperative opioids is achieved by using general anesthesia combined with intravenous opioid-based analgesia intra- and post-operatively in one group and general analgesia combined with epidural ropivacaine-based analgesia in the other group.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • general anesthesiaProcedure or surgery

    Patients will receive intraoperative and postoperative intravenous opioid-based analgesia for robot-assisted laparoscopic radical cystectomy.

  • general anesthesia combined with epidural analgesiaProcedure or surgery

    Patients will receive epidural ropivacaine-based analgesia for robot-assisted laparoscopic radical cystectomy.

What is being measured

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

  1. the number of circulating tumor cells

    The number of circulating tumor cells will be measured by collecting 5ml of venous blood sample.

    Measured: on the 3rd day after surgery

Secondary outcomes (4)
  1. the number of circulating tumor cells

    The number of circulating tumor cells will be measured by collecting 5ml of venous blood sample.

    Measured: immediately after the surgery

  2. the number of circulating tumor cells

    The number of circulating tumor cells will be measured by collecting 5ml of venous blood sample.

    Measured: on the 30 day after surgery

  3. Visual Analogue Scale

    Pain intensity will be assessed using the Visual Analogue Scale, which ranges from 0 to 10, with a higher score indicating greater pain intensity at 24 hours after surgery.

    Measured: at 24 hours after surgery

  4. Visual Analogue Scale

    Pain intensity will be assessed using the Visual Analogue Scale, which ranges from 0 to 10, with a higher score indicating greater pain intensity at 48 hours after surgery.

    Measured: at 48 hours after surgery

Questions about this trial

What is this clinical trial studying?

A study testing general anesthesia and general anesthesia combined with epidural analgesia in people with Bladder Cancer, run by RenJi Hospital at 1 site in China.

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 9 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 9 Aug 2021. 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 China. 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?

the number of circulating tumor cells (time frame: on the 3rd day after surgery). 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 NCT04358718, 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 9 Aug 2021.
