Radiation Therapy, Surgery, and Chemotherapy in Treating Patients With Rectal Cancer That Can Be Surgically Removed
A Phase 3 study testing fluorouracil, leucovorin calcium and conventional surgery in people with Colorectal Cancer, run by European Organisation for Research and Treatment of Cancer - EORTC at 35 sites in 10 countries.
Trial summary
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug, giving the drugs in different ways, and combining radiation therapy and surgery with chemotherapy may kill more tumor cells. Read more about this study

About this study
Official title: FOUR ARMS PHASE III CLINICAL TRIAL FOR T3-T4 RESECTABLE RECTAL CANCER COMPARING PRE-OPERATIVE PELVIC IRRADIATION TO PRE-OPERATIVE IRRADIATION COMBINED WITH FLUOROURACIL AND LEUCOVORIN WITH OR WITHOUT POST-OPERATIVE ADJUVANT CHEMOTHERAPY
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug, giving the drugs in different ways, and combining radiation therapy and surgery with chemotherapy may kill more tumor cells.
PURPOSE: Randomized phase III trial to compare radiation therapy alone before surgery with radiation therapy plus fluorouracil and leucovorin before surgery, with and without fluorouracil and leucovorin after surgery in patients with rectal cancer that can be surgically removed.
Read the detailed description
OBJECTIVES:
- Compare the disease-free and overall survival in patients with resectable adenocarcinoma of the rectum treated with preoperative radiotherapy with or without preoperative fluorouracil (5-FU) combined with leucovorin calcium (CF) and/or postoperative 5-FU/CF.
OUTLINE: This is a randomized, multicenter study. Patients are stratified according to center, sex, tumor location (0-5 vs 6-10 vs 11-15 cm from anal margin), and stage (T3 vs T4). Patients are randomized to 1 of 4 treatment arms.
- Arm I: Patients undergo involved-field radiotherapy 5 days a week for 5 weeks followed 3-10 weeks later by abdominoperineal resection or anal-sparing resection according to local practice in the absence of disease progression or unacceptable toxicity.
- Arm II: Patients undergo radiotherapy as in arm I beginning on day 1 and leucovorin calcium (CF) IV followed by fluorouracil (5-FU) IV (1 hour before radiotherapy) on days 1-5 and 29-33, followed 3-10 weeks later by resection as in arm I in the absence of disease progression or unacceptable toxicity.
- Arm III: Patients undergo radiotherapy followed 3-10 weeks later by resection as in arm I. Within 3-10 weeks after resection, patients receive CF followed by 5-FU on days 1-5. Chemotherapy continues every 4 weeks for 4 courses in the absence of disease progression or unacceptable toxicity.
- Arm IV: Patients undergo preoperative radiotherapy with concurrent chemotherapy followed by resection as in arm II and postoperative chemotherapy as in arm III.
Patients are followed every 6 months.
PROJECTED ACCRUAL: A total of 992 patients will be accrued for this study within 4 years.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing fluorouracil, leucovorin calcium and conventional surgery in people with Colorectal Cancer, run by European Organisation for Research and Treatment of Cancer - EORTC at 35 sites in 10 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
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 2 Sep 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 35 sites in France, Belgium, Spain, Netherlands, Switzerland and 5 more countries. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00002523, which also lists 13 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 2 Sep 2016.
