简要总结
RATIONALE: Monoclonal antibodies, such as cetuximab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Cetuximab may also stop the growth of tumor cells by blocking blood flow to the tumor. Radiation therapy uses high energy x- rays to kill tumor cells. Cetuximab may also make tumor cells more sensitive to radiation therapy. Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. It is not yet known which regimen of radiation therapy, combination chemotherapy, and cetuximab and is most effective in treating patients with head and neck cancer.
PURPOSE: This randomized phase II trial is comparing two different regimens of radiation therapy given together with combination chemotherapy and cetuximab to see how well they work in treating patients with newly diagnosed stage III or stage IV head and neck cancer that cannot be removed by surgery.
详细描述
OBJECTIVES:
- To determine the safety profile of chemoradiotherapy with carboplatin vs cisplatin in patients with newly diagnosed, unresectable stage III or IV squamous cell carcinoma of the head and neck.
- To select one of these chemoradiotherapy regimens to be used as an experimental arm in a future phase III trial.
- To look for EGFR expression and downstream signaling in reacting skin samples from patients experiencing skin toxicity and in normal skin samples from the same patients for comparison with skin samples from patients who have not shown skin toxicity.
- To explore which factors related to EGFR predict the biological activity of cetuximab in patients treated with these regimens.
OUTLINE: This is a multicenter study.
Patients receive induction chemotherapy comprising docetaxel IV over 1 hour and cisplatin IV over 1 hour on day 1 and fluorouracil IV continuously over 24 hours on days 1-5. Treatment repeats every 3 weeks for up to 4 courses in the absence of unacceptable toxicity.
Within 3 weeks after completion of induction chemotherapy or within 5 weeks from the start of the last chemotherapy course (day 21), patients are stratified by institution and treatment response (stable disease [SD], partial response [PR], or complete response [CR] vs non-response [progressive disease]). Patients with progressive disease are removed from study and patients with SD, PR, or CR are randomized to 1 of 2 treatment arms.
