Comparison of Adjuvant Chemotherapy Regimens in Treating Stage II/III Rectal Cancer
Intergroup Randomized Phase III Study of Postoperative Irinotecan, 5-Fluorouracil and Leucovorin vs. Oxaliplatin, 5-Fluorouracil and Leucovorin vs. 5-Fluorouracil and Leucovorin for Patients With Stage II or III Rectal Cancer Receiving Either Preoperative Radiation and 5-Fluorouracil or Postoperative Radiation and 5-Fluorouracil

Brief Summary
This randomized phase III trial is comparing the effectiveness of three adjuvant combination chemotherapy regimens in treating patients who are receiving radiation therapy and fluorouracil either before or after surgery for stage II or stage III rectal cancer. Drugs used in chemotherapy, such as irinotecan, fluorouracil, leucovorin, and oxaliplatin, use different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. It is not yet known which adjuvant combination chemotherapy regimen is more effective in treating patients who are receiving radiation therapy and fluorouracil either before or after surgery for rectal cancer.

Outcome Measures
Primary Outcomes (1)
3-year Overall Survival Rate
Overall survival (OS) was defined as time from randomization to death from any cause. 3-year OS rate was estimated using Kaplan-Meier method.
assessed every 3 months withihn 2 years of study entry, every 6 monhts between years 3-5 and then annually for 5 years, estimated at 3 years
Secondary Outcomes (3)
3-year Disease Free Survival
assessed every 3 months withihn 2 years of study entry, every 6 monhts between years 3-5 and then annually for 5 years, estimated at 3 years
Proportion of Sphincter Preservation
assessed at primary surgery time
Failure Pattern
assessed every 3 months withihn 2 years of study entry, every 6 monhts between years 3-5 and then annually for 5 years
Study Arms (6)
Group I, Arm I
EXPERIMENTALPatients receive 1 of 3 preoperative chemo and radiotherapy treatment regimens, determined by the treating physician. Within 21-56 days after the completion of chemoradiotherapy, patients undergo surgical resection. Patients receive irinotecan IV over 90 minutes and leucovorin calcium IV over 2 hours followed immediately by fluorourcil IV bolus on day 1. Treatment continues in the absence of disease progression or unacceptable toxicity.
Group I, Arm II
EXPERIMENTALPatients receive 1 of 3 preoperative chemo and radiotherapy treatment regimens, determined by the treating physician. Within 21-56 days after the completion of chemoradiotherapy, patients undergo surgical resection. Patients receive oxaliplatin IV over 2 hours and leucovorin calcium IV over 2 hours followed immediately by fluorourcil IV bolus on day 1. Patients also receive fluorouracil IV continuously over 46 hours beginning on day 1. Treatment repeats every 2 weeks for 8 courses. Treatment continues in the absence of disease progression or unacceptable toxicity.
Group I, Arm III
EXPERIMENTALPatients receive 1 of 3 preoperative chemo and radiotherapy treatment regimens, determined by the treating physician. Within 21-56 days after the completion of chemoradiotherapy, patients undergo surgical resection. Patients receive leucovorin calcium IV over 2 hours and fluorouracil IV over 1 hour on days 1, 8, 15, 22, 29, and 36. Treatment repeats every 8 weeks for 3 courses. Treatment continues in the absence of disease progression or unacceptable toxicity.
Group II, Arm I
EXPERIMENTALPatients receive irinotecan, leucovorin calcium, and fluorouracil as in group 1, arm I for 4 courses. Within 4 weeks after the completion of chemotherapy, all patients undergo concurrent pelvic chemoradiotherapy as described in group 1 preoperative chemo and radiotherapy Regimen A, B, or C, followed 4-6 weeks later by 4 additional courses of adjuvant chemotherapy for arms I and II and 2 additional courses of adjuvant chemotherapy for arm III. Treatment continues in the absence of disease progression or unacceptable toxicity.
Group II, Arm II
EXPERIMENTALPatients receive oxaliplatin, leucovorin calcium, and fluorouracil as in group 1, arm II for 4 courses. Within 4 weeks after the completion of chemotherapy, all patients undergo concurrent pelvic chemoradiotherapy as described in group 1 preoperative chemo and radiotherapy Regimen A, B, or C, followed 4-6 weeks later by 4 additional courses of adjuvant chemotherapy for arms I and II and 2 additional courses of adjuvant chemotherapy for arm III. Treatment continues in the absence of disease progression or unacceptable toxicity.
Group II, Arm III
EXPERIMENTALPatients receive leucovorin calcium and fluorouracil as in group 1, arm III for 1 course. Within 4 weeks after the completion of chemotherapy, all patients undergo concurrent pelvic chemoradiotherapy as described in group 1 preoperative chemo and radiotherapy Regimen A, B, or C, followed 4-6 weeks later by 4 additional courses of adjuvant chemotherapy for arms I and II and 2 additional courses of adjuvant chemotherapy for arm III. Treatment continues in the absence of disease progression or unacceptable toxicity.

Eligibility Criteria
You may qualify if:
- Patients must have histologically proven adenocarcinoma of the rectum with no distant metastases. Clinical staging is required (T3N0M0, T4N0M0, TanyN1-3M0).
- Patients must not have evidence of tumor outside of the pelvis including liver metastases, peritoneal seeding, or metastatic inguinal lymphadenopathy.
- The distal border of the tumor must be at or below the peritoneal reflection, defined as within 12 cm of anal verge by proctoscopic examination. In addition, patients who have had a portion of their tumors confirmed to be below the peritoneal reflection at the time of surgery are eligible regardless of the distance determined by endoscopy.
- Transmural penetration of tumor through the muscularis propria must be demonstrated by CT scan, endo-rectal ultrasound or MRI.
- Tumors must be defined prospectively by the surgeon as clinically resectable or not.
- Clinically resectable tumors will be defined by the surgeon as not fixed and completely resectable with negative margins based on the routine examination of the non-anesthetized patient.
- Before pre-op treatment, the surgeon should estimate and record the type of resection anticipated: APR, LAR or LAR/coloanal anastomosis.
- The tumor may be clinically fixed or initially not completely resectable, clinical stage T4 N0-2 M0 based on the presence of at least one of the following criteria:
- Clinically fixed tumors on rectal examination with tumor adherent to the pelvic sidewall or sacrum.
- Hydronephrosis on CT scan or IVP or ureteric or bladder invasion as documented by cystoscopy and cytology or biopsy, or invasion into prostate.
- Vaginal or uterine involvement.
- Patients must not have a previous or concurrent malignancy, with the exception of:
- Nonmelanoma skin cancer or in situ cervical cancer.
- Treated non-pelvic cancer from which the patient has been continuously disease-free for \>5 years.
- Patients must have ECOG performance status 0-1.
- +3 more criteria
You may not qualify if:
- Patients have received prior chemotherapy or pelvic irradiation therapy.
- Female patients must not be pregnant or breast-feeding.
- Patients have an active inflammatory bowel disease or other serious medical illness which might limit the ability of the patient to receive protocol therapy.
- Group II (Post-operative) Registration
- Patients must have had histologically proven adenocarcinoma of the rectum with no distant metastases. Pathologic staging is required (T3N0M0, T4N0M0, TanyN1-3M0).
- Patients must not have evidence of tumor outside of the pelvis including liver metastases, peritoneal seeding, or metastatic inguinal lymphadenopathy.
- The distal border of the tumor must have been at or below the peritoneal reflection, defined as within 12 centimeters of anal verge by proctoscopic examination.

- Patients must not have received prior chemotherapy or pelvic irradiation therapy.
- Patients must not have a previous or concurrent malignancy, with the exception of:
