| Inclusion Criteria: | 1) Patients must have histologically or cytologically confirmed metastatic or recurrent head and neck squamous cell carcinoma from the primary lesions and/or lymph nodes of the oral cavity, oropharynx, hypopharynx, or larynx.
2) Patients must have measurable disease, defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded) as >/= 20 mm with conventional techniques or as >/= 10 mm with spiral CT scan.
3) Patients have received one or more chemotherapy regimens.
4) Age >/= 18 years.
5) Life expectancy of greater than 3 months.
6) No acute intercurrent illness or infection.
7) ECOG performance status </= 2 (Karnofsky >/= 60%)
8) Laboratory parameters: WBC >3,000/mL; Neutrophils >1,500/mL; Hemoglobin >8g/dL; Platelets >100,000/mL; Bilirubin <1.5 times the upper limit of normal; Serum creatinine: within normal institutional limits; ALT/AST < 3 x institutional upper limit of normal (ULN) if alkaline phosphatase is < ULN, except in known hepatic metastasis, wherein ALT/AST may be </= 5 x ULN
9) Creatinine clearance: The standard Cockcroft and Gault formula or the measured glomerular filtration rate (GFR) using the appropriate radiolabeled method (51-CrEDTA or Tc99m-DTPA) must be used to calculate CrCl for enrollment or dosing. The same method used at baseline should be used throughout the study. No dosage adjustment is needed in patients with CrCl >/= 45 mL/min.
10) Patients with a history of non-melanoma skin cancer, or other malignancies treated 5 years or more prior to the current tumor, from which the patient has remained continually disease-free, are eligible.
11) Ability to understand and the willingness to sign a written informed consent document. |
