Five Fractions of Radiotherapy Followed by Full Dose FOLFOX Chemotherapy as Preoperative Treatment for Rectal Cancer

• Status: Completed
• Trial end date: 2014-09-01
• Target enrollment: 0
• Participant gender: All

Summary

To determine if short course radiotherapy followed by chemotherapy can maintain morbidity at or below levels reported with concurrent 5FU, oxaliplatin, and radiotherapy, while maintaining response rates comparable to what would be expected with radiotherapy and concurrent chemotherapy.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Washington University School of Medicine
• Treatments: Capecitabine; Fluorouracil; Leucovorin; Oxaliplatin

Criteria

Inclusion Criteria:

• Biopsy proven adenocarcinoma of the rectum

• Patient evaluated by surgeon and found to be a potential surgical candidate. Since the primary objectives are response to chemoradiation and acute toxicity, lesions which are initially unresectable are eligible-provided the surgeon feels that, if there is sufficient response, surgery could become feasible.

• Clinical evidence of T3 or T4 disease. This can be by imaging studies (see or by physical findings (tethering on palpation for T3 lesions or invasion of a neighboring organ for T4 lesions)

• Karnofsky Performance Status at >60

• Laboratory criteria:

• Absolute neutrophil count >= 1.5 K

• Platelets >= 100 K

• Total Bilirubin <= 2.0;

• SGOT and Alkaline Phosphatase <= 2 x upper limit of normal

• Creatinine < 2.0

• Hemoglobin >= 8.0

• Informed consent signed

• Tumor measurable in at least one dimension. This may be, e.g. length and/or width measured endoscopically or on digital rectal examination, and maximum rectal wall thickness determined by imaging studies.

• Estimated longevity at least 12 months

• Patients with distant metastatic disease will be eligible if they satisfy all other conditions

Exclusion Criteria:

• Pregnant women, children < 18 years, or patients unable to give informed consent

• Patients with a past history of pelvic radiotherapy.

• Patients with any other malignancy within the past 5 years except: skin cancer or in-situ cervical cancer

• Patients with known allergy/intolerance to 5FU, Leucovorin, Oxaliplatin, Capecitabine

• Prior chemotherapy for colorectal cancer.

• Grade >= 2 peripheral neuropathy

• Any condition which, in the opinion of the treating medical oncologist, renders the patient unfit for 5FU (oral capecitabine if 5FU is unavailable), Leucovorin, Oxaliplatin chemotherapy
