About

RATIONALE: Biological therapies such as erlotinib may interfere with the growth of tumor cells and slow the growth of the tumor.

PURPOSE: Phase II trial to determine the effectiveness of erlotinib in treating patients who have locally advanced and/or metastatic endometrial cancer.

Full description

OBJECTIVES:

• Determine the efficacy of erlotinib, in terms of response rate and duration of stable disease, in patients with locally advanced and/or metastatic carcinoma of the endometrium.
• Determine the toxicity of this drug in these patients.
• Determine the time to progression and duration of response in patients treated with this drug.
• Correlate objective tumor response with levels of epidermal growth factor receptor expression in patients treated with this drug.

OUTLINE: This is a multicenter study.

Patients receive oral erlotinib once daily. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Patients are followed at 4 weeks. Patients with complete or partial response or stable disease are also followed every 3 months until relapse or death.

PROJECTED ACCRUAL: A total of 15-30 patients will be accrued for this study within 12-18 months.

Sex: Female

Ages: 18+ years old

Volunteers: No Healthy Volunteers
