Enrollment: 26
Healthy volunteers: no

Brief summary:
This phase II clinical trial studies the side effects and how well imatinib mesylate works in treating patients with uterine cancer that has failed to respond to initial chemotherapy or has re-grown after therapy. Imatinib mesylate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Detailed description:
PRIMARY OBJECTIVES:

I. To determine the activity of Gleevec\^trademark (TM) (imatinib mesylate) as measured by progression-free survival at six months.

II. To determine the frequency and severity of adverse effects of Gleevec\^TM in this cohort of patients as assessed by the Common Terminology Criteria of Adverse Events version 3.0 (CTCAE v3.0).

SECONDARY OBJECTIVES:

I. To determine the distribution of progression-free survival and overall survival.

II. To estimate the objective response rate (partial and complete response as defined under the Response Evaluation Criteria In Solid Tumors \[RECIST\] criteria).

III. To determine the effects of prognostic factors such as initial performance status and histological grade.

TERTIARY OBJECTIVES:

I. To determine the levels of expression of v-kit Hardy-Zuckerman 4 feline sarcoma viral oncogene homolog (c-KIT), platelet-derived growth factor receptor (PDGFR), v-akt murine thymoma viral oncogene homolog 2 (AKT2), and phosphorylated (p)-AKT2 in archived, formalin-fixed, paraffin-embedded primary tumors collected prior to the initiation of first-line chemotherapy

OUTLINE:

Patients receive imatinib mesylate orally (PO) once daily (QD) or twice daily (BID) on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 3 months for 2 years and then every 6 months for 3 years.

Arms:
arm 1: Patients receive imatinib mesylate PO QD or BID on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Interventions: intervention 1: imatinib mesylate intervention 2: laboratory biomarker analysis
Intervention descriptions: intervention 1: Given PO intervention 2: Correlative studies
