Brief summary:
The goal of this clinical research study is to learn if cetuximab can help to control the disease in patients who have recurrent endometrial cancer.

Primary Objective:

1\. To determine the overall disease control rate of cetuximab in patients with progressive or recurrent endometrial cancer.

Secondary Objectives:

1. To determine the duration of disease control, time to disease progression, and survival of this cohort of patients.
2. To determine the nature and degree of toxicity of cetuximab in this cohort of patients.
3. To correlate biologic markers with response to therapy if tissue is available.

Detailed description:
The epidermal growth factor receptor (EGFR) is a large protein that plays an important role in tumor growth. When EGFR is stimulated or "overexpressed," a series of chemical reactions happen that result in a tumor being "told" to grow. Researchers know that EGFR is overexpressed in many types of endometrial cancer. Cetuximab is designed to block this receptor, which may help to stop or slow the growth of tumors in those patients whose endometrial cancer has come back.

Before you can start treatment on this study, you will have "screening tests." These tests will help the doctor decide if you are eligible to take part in the study. If you have had some of the tests done recently, they may not need to be repeated. Your complete medical history will be recorded. You will have a physical exam, including a pelvic exam and measurement of vital signs (blood pressure, heart rate, temperature, and breathing rate). Blood (about 2-3 teaspoons) will be drawn for routine tests, tests of your kidney and liver function, and a pregnancy test for women who are able to have children. The pregnancy test must be negative for you to be allowed to take part in this study. You will have a chest x-ray and computed tomography (CT) or magnetic resonance imaging (MRI) scans of the abdomen and pelvis (stomach and hip area) to measure the tumor.

If you are found to be eligible to take part in this study, you will receive cetuximab once a week through a needle in a vein. Each treatment cycle is 4 weeks long. In the first week of your first treatment cycle only, you will receive cetuximab over 120 minutes (2 hours). For all additional treatments, you will receive cetuximab over 60 minutes. During the infusion and for 60 minutes after the infusion ends, you will be closely watched for signs of an allergic reaction.

You will receive diphenhydramine (or a similar antihistamine) by vein, about 30-60 minutes before receiving each cetuximab infusion. This is in order to lower the risk of side effects that the study drug may cause. Your doctor may decide to lower the dose of diphenhydramine in later doses.

Before each cycle of therapy and 1 month after treatment ends, you will have a physical exam. Blood (about 2-3 teaspoons) will be drawn for routine tests. CT scans or MRI will be repeated every 2-3 cycles and at the end of treatment. If you have any tumors in your chest, a chest x-ray will be repeated every 2-3 cycles and at the end of treatment. If you have a partial or complete response (the tumor shrinks or disappears completely) or the disease is stable (where the tumor has neither grown nor shrunk), the CT or MRI will be repeated 4 weeks later to check the response.

You will be able to keep receiving additional treatment cycles as long as you are benefitting. If the disease gets worse or you experience any intolerable side effects, you will be taken off the study.

After you have completed treatment on the study, the status of your health and the disease will be checked. Your doctor will decide how often these check-ups will occur. You may return to M. D. Anderson for these follow-up exams, or if you choose not to come in to the clinic, you will be contacted by phone to see how you are doing.

This is an investigational study. Cetuximab is commercially available and FDA approved for the treatment of colorectal cancer. Its use in the treatment of endometrial cancer in this study is experimental. Up to 40 patients will take part in this study. Up to 30 patients will be enrolled at M. D. Anderson.
