简要总结
The purpose of this study is to learn how to identify early which patients will respond to chemotherapy plus radiation therapy in order to reduce the number of subjects who require surgery (followed by radiation therapy).
详细描述
In this study one cycle of chemotherapy will be administered and then those subjects who respond well to that cycle will be started on radiation therapy along with chemotherapy and those that don't respond well to the initial cycle of chemotherapy, will undergo a total laryngectomy (surgery to remove the voice box) followed by radiation therapy. The initial cycle of chemotherapy consists of the drugs Taxotere, Cisplatin, and 5-Fluorouracil (this combination is known as TPF). Then on Day 20 of the study, the subjects will be administered another chemotherapy agent called cetuximab (a.k.a. C-225). It will then be determined if the patient's response to the chemotherapy was favorable by examining the patient's tumor with an endoscopy. If the response is determined to be good, then the patient will continue with a chemotherapy regimen with the addition of radiation therapy combination. If the patient's response to the chemotherapy is determined to be less than favorable, then the patient will be advised to undergo salvage surgery (a.k.a. laryngectomy) to remove their voice box and then undergo radiation therapy treatment. Additionally, tumor tissue samples and blood will be studied to see if there are special molecular markers that help predict when a tumor will respond to chemotherapy and radiation treatment.

研究组 & 干预措施
Chemotherapy/Radiation/Surgery
Patients will undergo induction chemotherapy with (TPF): Docetaxel (Taxotere) 75 mg/m2 and cisplatin 100 mg/m2 on day 1, and 5-FU 750 mg/m2 days 1-4.
On day 20 patients will receive a single dose of cetuximab (C-225) 400 mg/m2.
Depending upon disease response, patients will undergo salvage laryngectomy followed by radiation therapy and chemotherapy.

结局指标
主要结局
Percentage of Patients Achieving Histologic Complete Response
时间窗: 3 years
The proportion of patients treated with radiation+cetuximab achieving histologic CR will be estimated, along with 95% exact confidence intervals. Histologic Complete Response (CR) will be defined as primary tumors exhibiting a clinical CR or at least a 90% PR (Partial Response) along with a negative post-treatment biopsy.
次要结局
- Overall Survival Time(3 years)
- The Difference, From Baseline, in EGFR, for Tumor Biopsies Taken After the Administration of Cetuximab Following TPF.(Day 23)
- The Change in Overall Quality of Life Score During Radiation Therapy and at 6, 12, and 24 Months Post Treatment.(24 months)
- The Number of Patients That Experience Grade 3 and 4 Mucositis or Dysphagia(3 years.)
