About this study

Official title: Randomized Phase II Study of Adjuvant Chemotherapy With 5-FU/Leucovorin vs. Oxaliplatin/5-FU/Leucovorin After Preoperative Chemoradiotherapy With Fluoropyrimidines Followed by Surgery in Patients With Locally Advanced Rectal Cancer

The purpose of this study is to evaluate the disease-free survival in patients with locally advanced rectal cancer treated with preoperative chemoradiotherapy with fluoropyrimidines and surgery followed by adjuvant combination chemotherapy with oxaliplatin/5-FU/Leucovorin vs 5-FU/Leucovorin.

Read the detailed description

Preoperative chemoradiotherapy with fluoropyrimidines followed by surgery is one of the standard treatments for patients with locally advanced rectal cancer; however, the role of adjuvant chemotherapy is still controversial. The aim of this study is to investigate the efficacy of adjuvant FOLFOX for rectal cancer who underwent fluoropyrimidine based chemoradiotherapy and complete total mesorectal excision.

What is being measured

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

  1. Number of Participants With Disease Recurrence

    Disease-free survival will be measured as the time from the date of randomization to the date of disease relapse or death due to any cause. Using Cox-proportional hazard regression, the hazard ratio together with the 95% confidence interval will be reported, in addition to Kaplan-Meier estimates of the survival curves, including medians and rates with 95% confidence intervals. Intent-to-treat population included all randomised patients, and per-protocol population included patients who received at least 1 dose of chemotherapy without any violation of inclusion criteria

    Measured: up to 3 years after completion of treatment

  2. Number of Participants With Disease Recurrence With Pathological Stage III

    Disease-free survival will be measured as the time from the date of randomization to the date of disease relapse or death due to any cause. Using Cox-proportional hazard regression, the hazard ratio together with the 95% confidence interval will be reported, in addition to Kaplan-Meier estimates of the survival curves, including medians and rates with 95% confidence intervals. Intent-to-treat population included all randomised patients, and per-protocol population included patients who received at least 1 dose of chemotherapy without any violation of inclusion criteria.

    Measured: up to 3 years after completion of treatment

  3. Number of Participants With Disease Recurrence With Pathological Stage II

    Disease-free survival will be measured as the time from the date of randomization to the date of disease relapse or death due to any cause. Using Cox-proportional hazard regression, the hazard ratio together with the 95% confidence interval will be reported, in addition to Kaplan-Meier estimates of the survival curves, including medians and rates with 95% confidence intervals. Intent-to-treat population included all randomised patients, and per-protocol population included patients who received at least 1 dose of chemotherapy without any violation of inclusion criteria.

    Measured: up to 3 years after completion of treatment

Secondary outcomes (2)
  1. Death Rate

    overall survival was defined as the time from randomisation to death. We used the Kaplan-Meier method to estimate disease-free and overall survival. Patients were censored at the last follow-up if they were alive and free from disease recurrence. We used the log-rank test to compare the two survival distributions. We estimated crude and stratified hazard ratios (HRs) and their corresponding 95% CIs using the Cox proportionalhazards regression model.

    Measured: Up to 3 years after completion of treatment.

  2. Pattern of Recurrence

    After the completion of study treatment, chest radiography and measurement of carcinoembryonic antigen were done every 3 months for the fi rst 2 years and every 6 months thereafter. Abdominopelvic CT scans were done every 6 months and chest CT scans annually. Colonoscopy was scheduled at 1 year, 3 years, and 5 years from the date of surgery. Local recurrence was defined as any clinically proven tumour relapse within the pelvis or perineum. Distant metastasis was defined as relapse at any other site rather than local recurrence. We regarded any local or distant recurrence as a disease recurrence event. Disease recurrence was judged by the investigators with no central review.

    Measured: the time from the date of randomization to the date of disease relapse, , assessed up to 5 years

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Adjuvant FL and Adjuvant FOLFOX in people with Rectal Cancer, run by Asan Medical Center at 6 sites in South Korea.

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 8 inclusion and 3 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 23 Oct 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in South Korea. 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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 23 Oct 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Number of Participants With Disease Recurrence (time frame: up to 3 years after completion of treatment). 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 NCT00807911, 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 23 Oct 2024.
