A Clinical Trial Comparing Preoperative Radiation Therapy And Capecitabine With or Without Oxaliplatin With Preoperative Radiation Therapy And Continuous Intravenous Infusion Of 5-Fluorouracil With or Without Oxaliplatin In The Treatment Of Patients With Operable Carcinoma Of The Rectum

RATIONALE: Drugs used in chemotherapy, such as capecitabine, fluorouracil, and oxaliplatin work in 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. PURPOSE: This randomized phase III trial is studying radiation therapy and either capecitabine or fluorouracil with or without oxaliplatin and comparing them to see how well they work when given before surgery in treating patients with resectable rectal cancer. It is not yet known whether radiation therapy and either capecitabine or fluorouracil is more effective with or without oxaliplatin in treating rectal cancer.

Stanford is not currently accepting new patients for this trial. You may want to check to see if other locations are recruiting.

Ages Eligible For Study:

18 Years - N/A

Inclusion Criteria

- Patients must consent to participate in the study and must have signed and dated an IRB-approved consent form conforming to federal and institutional guidelines. - Patients must be > 18 years of age. - Patients must have a life expectancy of 5 years, excluding their diagnosis of cancer (as determined by the investigator), and must have an Eastern Cooperative Oncology Group (ECOG) (Zubrod) performance status of 0 or 1. - Patients must have a diagnosis of adenocarcinoma of the rectum obtained by a biopsy technique which leaves the major portion of the tumor intact. - The interval between the initial diagnosis of rectal adenocarcinoma and randomization must be no more than 42 days. - Prior to randomization, the investigator must specify the intent for sphincter saving or non-sphincter saving surgery. - The tumor must be either palpable by digital rectal exam or be accessible via a proctoscope or sigmoidoscope. - Distal border of the tumor must be located < 12 cm from the anal verge. - The tumor must be considered by the surgeon to be amenable to curative resection. (Note that curative resection can include pelvic exenteration.) - The tumor must be clinically Stage II (T3-4 N0 with N0 being defined as all imaged lymph nodes are < 1.0 cm) or Stage III (T1-4 N1-2 with the definition of a clinically positive node being any node > 1.0 cm). Stage of the primary tumor may be determined by ultrasound or Magnetic Resonance Imaging (MRI). Computed Tomography (CT) scan is acceptable provided there is evidence of T4 and/or N1-2 disease. - At the time of randomization, all patients must have had the following within the previous 42 days: history and physical examination; if technically feasible, a complete colonoscopic examination; if not feasible, a proctoscopic or sigmoidoscopic exam; clinical staging of the tumor; CT or MRI of the abdomen and pelvis (combined PET/CT may be substituted), and a chest x-ray (PA and lateral) or CT scan of the chest to exclude patients with metastatic disease. - At the time of randomization: Absolute neutrophil count (ANC) must be > 1,200/mm3; Platelet count must be > 100,000/mm3; There must be evidence of adequate hepatic function as follows: total bilirubin must be < 1.5 x the upper limit of normal (ULN) for the lab; and alkaline phosphatase must be < 2.5 x Upper Limit of Normal (ULN) for the lab; and the Aspartate Amino Transferase (AST) must be < 2.5 x ULN for the lab; and If AST is > ULN, serologic testing for Hepatitis B and C must be performed and results must be negative; Calculated creatinine clearance must be > 50 mL/min. - Patients with prior malignancies, including invasive colon cancer, are eligible if they have been disease-free for > 5 years and are deemed by their physician to be at low risk for recurrence. Patients with squamous or basal cell carcinoma of the skin, melanoma in situ, carcinoma in situ of the cervix, or carcinoma in situ of the colon or rectum that have been effectively treated are eligible, even if these conditions were diagnosed within 5 years prior to randomization.
