Complete Neoadjuvant Treatment for REctal Cancer (CONTRE)

• Status: Completed
• Trial end date: 2013-01-01
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this study is to find out how well patients with cancer of the rectum do if they get all of their other treatment - chemotherapy by itself followed by chemotherapy and radiation together - before surgery. Patients have recently been diagnosed with rectal cancer, and the doctors have recommended neo-adjuvant chemo treatment to try to shrink the cancer before removing it.

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

Details

• Lead Sponsor: William Sikov; William Sikov MD
• Collaborators: Memorial Hospital of Rhode Island; Rhode Island Hospital; The Miriam Hospital
• Treatments: Leucovorin; Oxaliplatin

Criteria

Inclusion Criteria

• Patients must have histologically proven adenocarcinoma of the rectum with no evidence of distant metastases.

• The tumor must be clinically Stage II (T3-4 N0 with N0 being defined as all imaged lymph nodes are < 1.0cm) or III (T1-4 N1-2 with the definition of a clinically positive node being any node > 1.0cm). Stage of the tumor may be determined by CT scan, endorectal ultrasound or MRI.

• Patients must have no evidence of distant metastases including liver metastases, peritoneal seeding, or inguinal lymphadenopathy.

• Patients must not have received prior chemotherapy or pelvic radiation for rectal cancer, or prior pelvic radiation for any other malignancy that would prevent the patient from receiving the required radiation treatments for this study.

• Patients must have a life expectancy of 5 years, excluding their diagnosis of cancer (as determined by the investigator).

• Patients must not have an active concurrent invasive malignancy. Patients with prior malignancies, including invasive colon cancer, are eligible if they 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 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.

• Patients must be > 18 years of age, ECOG performance status 0-1.

• ANC > 1,500/µl, platelets > 100,000/µl, total bilirubin < 2.0 mg/dl or direct bilirubin < 1.0 mg/dl, alkaline phosphatase < 3xULN, ALT < 3xULN, creatinine < 1.5xULN.

• The patient must have been evaluated by a surgeon, radiation oncologist and medical oncologist and all must concur that the patient is appropriate for this study.

• Signed informed consent; able to comply with study and/or follow- up procedures

• Peripheral neuropathy < grade 1

Exclusion Criteria:

• Evidence of metastatic disease.

• Rectal cancers other than adenocarcinoma, i.e., sarcoma, lymphoma, carcinoid, squamous cell carcinoma, cloacogenic carcinoma, etc.

• Pregnancy or lactation at the time of proposed randomization. Eligible patients of reproductive potential (both sexes) must agree to use adequate contraception.

• Any therapy for this cancer prior to randomization.

• Synchronous invasive colon cancer.

• Nonmalignant systemic disease (cardiovascular, renal, hepatic, etc.) that would preclude the patient from receiving any chemotherapy treatment option or would prevent required follow-up.

• Patients with active inflammatory bowel disease, abdominal fistula, gastrointestinal perforation, or intraabdominal abscess within 6 months prior to Day 0 or other serious medical illness which might limit the ability of the patient to receive protocol therapy.

• Prior pelvic irradiation for any indication.

• Known hypersensitivity to 5-fluorouracil or oxaliplatin

• Psychiatric or addictive disorders or other conditions that, in the opinion of the investigator, would preclude the patient from meeting the study requirements.
