Purpose
This study utilizes two cycles of Paclitaxel and Carboplatin chemotherapies followed by four small doses of radiation, prior to other treatment (surgery or radiation). This study is evaluating if radiation as a chemoenhancer increases the response rate of initial therapy.

Detailed Description:
Cancers of the head and neck (H&N) comprise 5% of all cancers, with 40,000 new cases diagnosed annually. Surgery followed by irradiation or irradiation alone has been the standard of care for locally advanced Stage III and IV patients. With this approach, fewer than 30% of patients achieve long-term remission, and most recur locoregionally. Neoadjuvant chemotherapy has been administered prior to definitive therapy with response rates ranging from 60-90%; with pathologic CR rates documented in 30-70% of clinical responders. However, large randomized trials have shown no improvement in overall survival.
Because induction chemotherapy alone does not appear to improve long-term disease free survival in advanced head and neck cancers, concomitant chemotherapy and radiation has been pursued in patients with locally advanced head and neck cancers. Improved disease-free survival has been demonstrated with a variety of agents. The concept of synergy between radiation and chemotherapy is well established in vitro. Various schedules of radiation and chemotherapy have been utilized including weekly chemotherapy during radiation, chemotherapy given every three weeks during hyperfractionated radiation and alternating chemotherapy and radiation.
One exciting new chemotherapeutic agent, Paclitaxel has been shown to radiosensitize cancer cell lines in vitro. Recent studies have added Carboplatin to Paclitaxel in tandem or concurrently with radiation in hopes of improving response rates. From in-vitro data, it appears that the optimum schedule for the combination of Paclitaxel and radiation is to first induce G2/M arrest with Paclitaxel and follow this with radiation therapy. In a recent study by Chendil, et al, a novel radiation scheme appeared to enhance the response of both p53 wild type and p53 mutant cancer cell lines to chemotherapy. In vitro data with Carboplatin also indicates an additive effect when given prior to irradiation using various cell lines. What has not been evaluated, is whether a neoadjuvant regimen of Paclitaxel and Carboplatin followed by 4 small fractions of radiation can be given safely and effect an improved response rate in patients with bulky T2, Stage III and IV H&N cancer. We propose the use of two cycles of Paclitaxel and Carboplatin followed by four small fractions of radiation, prior to definitive treatment (surgery or radiation). It is hoped that using radiation as a chemoenhancer will increase the response rate to induction therapy in this population of patients.
Eligibility| Ages Eligible for Study: | 18 Years and older |
| Genders Eligible for Study: | Both |
| Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Adult patients greater than 18 years of age.
- ECOG performance status of 0, 1 or 2.
- Patients with pathologically documented bulky T2, III and IV squamous cell cancer of the head and neck (excluding M1 disease), within 2 months of diagnosis. Bulky T2 tumors are defined as those that have a volume of disease greater than 35 cm3 as measured by CT or MRI scan (26).
Patients will be medically fit for undergoing chemotherapy. Specifically:
- no evidence of active angina pectoris or ventricular arrhythmias; no myocardial infarction within the last six months. (Patients with medically controlled hypertension or congestive heart failure are eligible.)
- an absolute neutrophil count of > 1000/uL and platelet count > 100,000/uL
- serum total bilirubin < 1.5 mg/dL
Creatinine Clearance greater than 50 ml/min
Using an actual or calculated creatinine clearance using the formula:
(140 - age) x (wgt in kg)*/(serum creatinine)x(72)*= multiply by 0.85 for females
- if a pre-existing grade I neuropathy exists, patients must be willing to risk worsening neuropathy secondary to Paclitaxel. Patients with grade II or greater neuropathy will be excluded from study.
- ability to give written, informed consent to participate in the trial.
- Patients will have measurable disease as determined by MRI or CT scan or evaluable disease determined by panendoscopy to be eligible for enrollment on this study.
Exclusion Criteria:
- Pregnant females. Males and women of childbearing potential must use effective contraception in order to prevent pregnancy during therapy.
- Patients with a history of previous or current malignancy at other sites diagnosed within the last 5 years, with the exception of adequately treated carcinoma in-situ of the cervix or basal or squamous cell carcinoma of the skin. Patients with a history of other malignancies, who remain free of recurrence or metastases for greater than five years are eligible.
- Patients with active infection will not be eligible for this protocol until the infection is treated and the symptoms have clinically resolved.
- Patients with a history of allergy to drugs utilizing Cremophor in the formulation.
- Prior induction chemotherapy, prior irradiation or surgery will not be allowed.
- Patients with metastatic disease will not be eligible for this study.
- Patients with grade II or greater peripheral neuropathy will be excluded from study.
