About

RATIONALE: Imatinib mesylate may stop the growth of cancer cells by blocking the enzymes necessary for cancer cell growth.

PURPOSE: Phase II trial to determine the effectiveness of imatinib mesylate in treating patients who have refractory or relapsed ovarian epithelial, fallopian tube, or primary peritoneal cancer, or ovarian low malignant potential tumor.

Full description

OBJECTIVES:

• Determine the clinical activity of imatinib mesylate in patients with recurrent or relapsed ovarian epithelial, fallopian tube, or primary peritoneal cancer or ovarian low malignant potential tumor.
• Correlate the biochemical modulation of signal transduction pathways downstream of platelet-derived growth factor receptor (PDGFR) and c-kit tyrosine kinases in biopsy tissue with outcome in patients treated with this drug.
• Correlate the expression of PDGFR and c-kit in both archival and fresh biopsy tissue with response and outcome in patients treated with this drug.
• Investigate the potential antiangiogenic activity of this drug in microdissected tumor cell and stromal lysates of these patients.
• Investigate the potential for collateral receptor tyrosine kinase inhibition in biopsy tissue of patients treated with this drug.
• Evaluate the application of surface-enhanced laser desorption and ionization with time-of-flight detection (SELDI-TOF) with artificial intelligence bioinformatics to serially obtained serum samples for prediction of response in these patients and/or toxicity of this drug.

OUTLINE: Patients receive oral imatinib mesylate once daily on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

PROJECTED ACCRUAL: Up to 47 patients will be accrued for this study within 12-20 months.

Sex: Female

Volunteers: No Healthy Volunteers
