简要总结
RATIONALE: Drugs used in chemotherapy, such as irinotecan, leucovorin, fluorouracil, 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. Combining radiation therapy with chemotherapy may kill more tumor cells.
PURPOSE: This phase II trial is studying how well different regimens of induction chemotherapy followed by chemoradiotherapy work in treating patients with locally advanced adenocarcinoma of the rectum.
详细描述
OBJECTIVES:
- Determine the feasibility of obtaining a pre-treatment determination of intratumoral molecular markers (TS, DPD, and ERCC-1) for use in selection of the appropriate regimen for induction cytotoxic combination chemotherapy in patients with cT3-4 rectal adenocarcinoma.
- Determine the response probability (unconfirmed, complete and partial) in patients treated with targeted induction cytotoxic chemotherapy.
- Determine the toxicity of targeted induction cytotoxic chemotherapy and chemoradiotherapy in these patients.
- Determine the response probability in these patients treated with chemoradiotherapy.
OUTLINE: This is a multicenter study.
-
Induction chemotherapy: Patients are assigned to 1 of 3 treatment groups based on molecular analysis of the pretreatment tumor specimen.
-
Group I (lower likelihood of resistance to a fluorouracil-based regimen): Patients receive irinotecan IV over 90 minutes and leucovorin calcium IV over 2 hours on day 1 and fluorouracil IV over 46 hours beginning on day 1.
-
Group II (higher likelihood of resistance to a fluorouracil-based regimen): Patients receive oxaliplatin IV over 2 hours and irinotecan IV over 90 minutes on day 1.
-
Group III (high likelihood of sensitivity to oxaliplatin and fluorouracil therapy): Patients receive oxaliplatin IV over 90 minutes and leucovorin calcium IV over 2 hours on day 1 and fluorouracil IV over 46 hours beginning on day 1.
