Gefitinib in Treating Patients With Cervical Cancer
Gefitinib in Treating Patients With Cervical Cancer
RATIONALE: Biological therapies such as gefitinib may interfere with the growth of the tumor
 cells and slow the growth of cervical cancer. Comparing results of diagnostic procedures
 performed before, during, and after treatment with gefitinib may help doctors predict a
 patient's response to treatment and help plan the most effective treatment.

 PURPOSE: This phase II trial is studying how well gefitinib works in treating patients with
 cervical cancer.
OBJECTIVES:

 -  Determine the reduction in phosphorylation of epidermal growth factor receptor (EGFR),
 AKT, and ERK by proteomics in tumor and normal skin of patients with ovarian epithelial
 cancer or cervical cancer receiving gefitinib. (Open to accrual for cervical cancer
 patients only as of 4/5/2005)

 -  Determine the clinical activity of this drug in these patients.

 -  Determine the toxicity of this drug in these patients.

 -  Correlate the biologic modulation of EGFR, ERK, and AKT by this drug with outcome and
 toxic effects in these patients.

 -  Correlate EGFR modulation in skin with outcome and toxic effects in patients treated
 with this drug.

 -  Correlate expression of EGFR and phosphorylated-EGFR in tissue biopsies from these
 patients with biochemical modulation and outcome.

 -  Determine the application of surface-enhanced laser desorption and ionization with
 time-of-flight detection (SELDI-TOF) and artificial intelligence bioinformatics to
 serially obtained serum samples for predicting response and toxic effects in these
 patients.

 OUTLINE: Patients are stratified according to disease (cervical cancer vs ovarian epithelial,
 fallopian tube, and primary peritoneal cancer). (Open to accrual for cervical cancer patients
 only as of 4/5/2005)

 Patients receive oral gefitinib daily. Treatment continues every 28 days in the absence of
 disease progression or unacceptable toxicity.

 Biopsies of a sentinel lesion (with CT guidance or laparoscopy) are obtained at baseline and
 at 4 weeks. Skin biopsies of unaffected areas are also obtained at these time points. Tissue
 is examined using immunohistochemical methods. Proteomic profiling using surface-enhanced
 laser desorption/ionization with time-of-flight (SELDI-TOF) mass spectrometry is conducted on
 serum at baseline and then every 4 weeks.

 Patients are followed monthly.

 PROJECTED ACCRUAL: A total of 30-40 patients (15-20 per stratum) will be accrued for this
 study within 10-12 months. (Open to accrual for cervical cancer patients only as of 4/5/2005)
