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.
|Condition or disease||Intervention/treatment||Phase|
|Head and Neck Cancer||Biological: cetuximab Drug: carboplatin Drug: cisplatin Drug: docetaxel Drug: fluorouracil Genetic: fluorescence in situ hybridization Genetic: molecular genetic technique Genetic: reverse transcriptase-polymerase chain reaction Other: immunoenzyme technique Other: immunohistochemistry staining method Other: laboratory biomarker analysis Procedure: biopsy Radiation: 3-dimensional conformal radiation therapy Radiation: intensity-modulated radiation therapy||Phase 2|
- 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.
- Arm I: Patients undergo radiotherapy (RT) (3-dimensional conformal RT or intensity-modulated RT) on days 1-5 weekly for up to 7 weeks. Beginning on day 1 of RT, patients receive cisplatin IV over 1 hour once weekly for up to 7 weeks.
- Arm II: Patients undergo RT as in arm I. Beginning on day 1 of RT, patients receive carboplatin IV over 1 hour once weekly for up to 7 weeks.
Patients in both arms receive cetuximab IV over 1-2 hours once weekly beginning on day 1 of induction chemotherapy and continuing until the end of concurrent chemoradiotherapy.
Primary tumor tissue and skin biopsies, including fixed paraffin-embedded tissue specimens or frozen tissue, are collected at baseline (prior to treatment) and after completion of study treatment for correlative laboratory studies of EGFR expression and downstream signaling. Specimens are assessed by immunohistochemistry, fluorescence in situ hybridization, and reverse transcriptase-PCR sequencing of genes and proteins for ErbB-related activation. In the event of skin toxicity during treatment, patients undergo at least two additional biopsies, one in reacting skin and one in normal skin. Samples are assessed for markers of treatment efficacy related to cetuximab.
After completion of study therapy, patients are followed at 3 months and periodically thereafter.
