Oxaliplatin, Leucovorin, and Fluorouracil Before and After Radiation Therapy and Surgery in Treating Patients With Rectal Cancer That Can Be Removed by Surgery

Phase 2
Completed
Conditions
Colorectal Cancer
Interventions
Procedure: adjuvant therapy
Procedure: neoadjuvant therapy
Procedure: therapeutic conventional surgery
Radiation: radiation therapy
Registration Number
NCT01263171
Lead Sponsor
Cardiff University
Brief Summary

RATIONALE: Drugs used in chemotherapy, such as oxaliplatin, leucovorin, and fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving chemotherapy before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving chemotherapy after surgery may kill any tumor cells that remain after surgery.

PURPOSE: This phase II trial is studying giving oxaliplatin, leucovorin, and fluorouracil together, before and after radiation therapy and surgery in treating patients with rectal cancer that can be removed by surgery.

Detailed Description

OBJECTIVES:

Primary

* To assess the feasibility of introducing 8 weeks of neoadjuvant oxaliplatin and fluorouracil followed by radiotherapy and immediate surgical resection in patients with resectable adenocarcinoma of the rectum.

Secondary

* Determine feasibility of achieving dose intensity for chemotherapy and radiotherapy in these patients.

* Determine the safety, in terms of NCI CTCAE version 4 toxicities, including postoperative complication rate (up to 30 days postoperatively), and late toxicity assessment at 1 year following surgery, in these patients.

* Determine how active is the neoadjuvant chemotherapy, in terms of down staging the rectal cancer, local recurrence-free, distant metastasis-free, and overall survival at 1 year following surgery in these patients.

Neoadjuvant therapy: Patients receive oxaliplatin and leucovorin (L-leucovorin or leucovorin calcium) IV over 2 hours on day 1 and fluorouracil IV over 46 hours on days 1-2. Treatment repeats every 2 weeks for up to 4 courses in the absence of disease progression or unacceptable toxicity.

Radiotherapy/Surgery: Beginning 1 week after completion of chemotherapy, patients undergo radiotherapy, followed by surgical resection of their primary tumor, within 7-14 days after completion of radiotherapy. Between 6-8 weeks following surgery, patients begin adjuvant therapy.

Adjuvant therapy: Patients receive oxaliplatin and leucovorin (L-leucovorin or leucovorin calcium) IV over 2 hours on day 1 and fluorouracil IV over 46 hours on days 1-2. Treatment repeats every 2 weeks for up to 8 courses in the absence of disease progression or unacceptable toxicity.

Blood and biopsy specimens are collected at baseline and periodically for translational research studies.

After completion of study therapy, patients are followed up periodically for 1 year.
