  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Study population: 1. The patients were diagnosed with colorectal cancer and the tumor was considered to have invaded the adjacent organs before surgery. 2. The patient experienced multivisceral resection for surgical T4b colorectal cancer from January 2010 to December 2021. 3. All of the operations were performed with either open or laparoscopic surgery.

Who may be able to join

  • The patient was pathologically diagnosed as colorectal adenocarcinoma by endoscopic biopsy before operation.
  • All patients were considered to have tumors invading adjacent organs after preoperative radiographic evaluation.
  • All patients were recommended to undergo radical surgery after preoperative multidisciplinary consultation.

Who cannot join

  • Patients with distant metastasis or recurrent colorectal cancer were excluded.

About this study

This study attempts to compare safety and long-term oncological outcomes between laparoscopic surgery and open surgery in the treatment of clinical T4b Colorectal cancer.

Read the detailed description

Laparoscopic surgery is controversial for patients with T4b colorectal cancer who require multivisceral resection. With the expansion of the indications for laparoscopic surgery in recent years, surgeons try to perform laparoscopic multivisceral resection for the treatment of clinical T4b colorectal cancer. In this study, investigators attempted to compare safety and long-term oncological outcomes between laparoscopic surgery and open surgery in the treatment of clinical T4b colorectal cancer.

This study was a multicenter retrospective cohort study based on a multicenter database which contained hospitalization. According to the operation method, the patients were divided into laparoscopic multivisceral resection group(patients who underwent laparoscopic surgery or conversion to open surgery) and open multivisceral resection group(patients who underwent open surgery directly). The short-term and long-term result was compared between groups.

What is being measured

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

  1. Blood loss

    Blood loss is defined as intraoperative blood loss and measured in milliliters(ml).

    Measured: Until the end of the operation, an average of 8 hours.

  2. Complications

    Complications are defined as all surgery-related adverse events postoperatively, such as anastomotic leak, infection, which are measured in frequency.

    Measured: Until the patient recovered and was discharged from the hospital, an average of 10 days.

  3. Hospital stay after surgery

    Hospital stay after surgery is defined as the length of time from the end of surgery to the discharge of patient, which is measured in days.

    Measured: Until the patient recovered and was discharged from the hospital, an average of 10 days.

Secondary outcomes (2)
  1. Overall survival

    Overall survival is defined as the time from the surgery to death or last follow-up, regardless of disease recurrence, which was measured in months.

    Measured: The endpoint of the overall survival assessment is the last follow-up or patient death. Follow-up time is up to 72 months.

  2. Disease-free survival

    Disease-free survival is defined as the time from the surgery to disease recurrence or last follow-up, which was measured in months.

    Measured: The endpoint of the disease-free survival assessment is the last follow-up or disease recurrence. Follow-up time is up to 72 months.

Questions about this trial

What is this clinical trial studying?

An observational study of Colorectal Cancer, run by Cancer Institute and Hospital, Chinese Academy of Medical Sciences 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 3 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 27 Dec 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 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?

Blood loss (time frame: Until the end of the operation, an average of 8 hours.). The study lists 3 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 NCT05707598, 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 27 Dec 2024.
