About this study

Official title: Assessment of Autologous Blood Marker Localization and Intraoperative Colonoscopy Localization in Laparoscopic Colorectal Cancer Surgery: a Randomized Controlled Trial

Laparoscopic colorectal surgery has been proved to have similar oncological outcomes with open surgery. Due to the lack of tactile perception, surgeons may have misjudgments in laparoscopic colorectal surgery. Therefore, the accurate localization of a tumor before surgery is important, especially in the early stages of cancer. Recently, some retrospective studies reported the use of patients' autologous blood for preoperative colonic localization in colorectal cancer with successful detection by laparoscopy, but its benefits remain controversial. This study aimed to assess the accuracy and safety of autogenous blood marker localization in laparoscopic radical resection for colorectal cancer.

Read the detailed description

Laparoscopic surgery has become the standard for management of colorectal cancer(CRC) with the advantages of less traumatic procedure, but similar oncological outcomes to open surgery. Due to the lack of tactile perception (haptic feedback), surgeons may have misjudgments in patients with small or flat early colon cancer, malignant polyps resected by endoscopic mucosal resection or endoscopic submucosal dissection. Therefore, the accurate localization of a tumor before surgery is important, especially in the early stages of cancer, to clarify the extent of surgical resection.

Several methods are currently being proposed and used to identify the location of tumors. These include endoscopic tattooing with India ink, indocyanine green (ICG), preoperative endoscopic metal clipping with detection using an x-ray or palpation during surgery, and intraoperative endoscopy.

Recently, some retrospective studies reported the use of patients' autologous blood for preoperative colonic localization in CRC with successful detection by laparoscopy. Autologous blood was thought a feasible and safe tattooing agent for preoperative endoscopic localization. Nonetheless, all currently available evidence comes from observational studies that are susceptible to bias. We therefore proposed to conduct this randomized controlled clinical trial to evaluate the accuracy and safety of autogenous blood marker localization in laparoscopic radical resection for colorectal cancer.

  • Laparoscopic colorectal cancer resectionProcedure or surgery

    This is one of the routine procedures used for colorectal cancer resection.

Study groups in NCT05597384
Study groupRoleWhat they receive
Autologous Blood Marker GroupExperimentalThe tattooing was performed at 24-48 hours before the surgery. When the lesion was identified by endoscopy, 2-3 ml of the patient's peripheral venous blood without heparin preparation were injected submucosally at the distal side and proximal side of the lesion using a conventional endoscopic needle without submucosal injection of normal saline.
Receives: Procedure: Laparoscopic colorectal cancer resection
Intraoperative colonoscopy groupActive comparatorUnder general anesthesia with endotracheal intubation, the patient was placed in the modified lithotomy position. After routine laparoscopic exploration, CO2-insufflated intraoperative colonoscopy was performed using a flexible videocolonoscope. Upstream small bowel clamping was applied before intraoperative colonoscopy. During intraoperative colonoscopy, CO2 pneumoperitoneum was maintained by the insufflator so that the laparoscope could guide the colonoscope effectively.
Receives: Procedure: Laparoscopic colorectal cancer resection

What is being measured

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

  1. Autogenous blood marker localization was not inferior to intraoperative colonoscopy localization

    While checking the intraperitoneal cavity at the start of the surgery, the visibility of tattooing will be first checked. After the complete resection of the colon segment, resected colon specimen will be checked the localization with autologous blood tattooing. The localization accuracy of autologous blood marker will be similar to that of intraoperative colonoscopy localization.

    Measured: From the beginning of endoscopic tattooing to the end of the surgery.

Secondary outcomes (1)
  1. Adverse events related to endoscopic tattooing

    The secondary endpoint is the localization safety. Adverse events related to endoscopic tattooing, such as perforation, abscess formation, peritonitis, post-tattoo fever, post-tattoo abdominal pain, and intraperitoneal spillage of tattooing agent, were evaluated in autologous blood group.

    Measured: From the beginning of colonoscopic tattooing to 2 weeks after surgery.

Questions about this trial

What is this clinical trial studying?

A study testing Laparoscopic colorectal cancer resection in people with Colorectal Cancer, run by Shanghai East 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 7 inclusion and 10 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: status not confirmed, as of the sponsor's last update on 8 Mar 2023. 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?

Results are not available in the source record.

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

Contact Xiao-hua Jiang, MD ((8621)38804518, jiangxiaohuash@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Autogenous blood marker localization was not inferior to intraoperative colonoscopy localization (time frame: From the beginning of endoscopic tattooing to the end of the 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 NCT05597384, 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 8 Mar 2023.
