Fluorescent Dyes for Lymph Node Mapping

2014-08-27 03:14:52 | BioPortfolio

Summary

The goal of this clinical research study is to find lymph nodes before surgery using a dye called indocyanine green (IC-Green).

Objectives:

1. To determine the feasibility of using nonradioactive optical imaging techniques with indocyanine green (ICG) as a fluorescent contrast agent to identify all axillary lymph nodes.

2. To determine the feasibility of using nonradioactive optical imaging techniques with ICG as a fluorescent contrast agent to characterize lymphatic architecture and function in women with breast cancer who are scheduled for axillary node dissection

Description

Screening Tests:

Signing this consent form does not mean that you will be able to take part in this study. You will have "screening tests" to help the doctor decide if you are eligible to take part in this study. The following tests and procedures will be performed:

- Your medical history will be recorded.

- Women who are able to become pregnant must have a negative blood (about 2 tablespoons) or urine pregnancy test.

The study doctor will discuss the screening test results with you. If the screening tests show that you are not eligible to take part in the study, you will not be enrolled. Other treatment options will be discussed with you.

IC-Green Injections:

If you are found to be eligible to take part in this study, a member of the study staff will give you between 6-16 injections of IC-Green through a needle in your hand, arm, and breast. The study doctor will discuss the number of injections that you will receive in more detail. The injections will be given after you are under anesthesia.

This IC-Green injections will allow researchers to see the flow of the liquid through your body during imaging and locate the lymph nodes that will be removed during your standard of care surgery. After all of the IC-Green injections have been given, the imaging procedure will begin. Researchers will shine a special red light onto your skin causing the IC-Green to glow. The red light is like the red light in a grocery store scanner. The imaging procedure will take about 1 hour to complete.

Before the IC-Green injections and during imaging, a member of the research staff will monitor and record your vital signs (blood pressure, breathing rate, heart rate, and temperature).

After the IC-Green injections, a study staff member will closely monitor the injection site for possible side effects every 15 minutes during the first hour, and then every 30 minutes during the second hour.

Follow-Up Evaluation:

If you spend the night in the hospital after your surgery, a study staff member will visit you for a follow-up the day after surgery. At this visit, your temperature will be recorded and you will be asked how you are feeling and if you have had any side effects. The visit should last about 10 minutes.

If you do not spend the night in the hospital after surgery, you will be contacted by phone the day after surgery. You will be asked the same questions described above, as well as what your temperature is. The phone call should last about 10 minutes.

Length of Study:

After all of the images have been taken, and the follow-up evaluation is complete, your participation in this study will be over.

Additional Information:

If you have shortness of breath, please call 911 right away. If you have a reaction with redness, itchiness, and/or swelling at the injection sites before your follow-up evaluation, you should call Dr. Funda Meric-Bernstam at 713-745-4453 during business hours or contact the M. D. Anderson paging operator at 713-792-2121 and request to talk to Dr. Meric-Bernstam after business hours.

This is an investigational study. IC-Green is FDA approved and commercially available for mapping heart, liver, and eye function. The use of IC-Green for mapping the lymph nodes in breast cancer patients is investigational.

Up to 20 patients will be take part in this study. All will be enrolled at M. D. Anderson.

Medical and Biotech [MESH] Definitions

Abnormal accumulation of lymph in the arm, shoulder and breast area associated with surgical or radiation breast cancer treatments (e.g., MASTECTOMY).

Metastatic breast cancer characterized by EDEMA and ERYTHEMA of the affected breast due to LYMPHATIC METASTASIS and eventual obstruction of LYMPHATIC VESSELS by the cancer cells.

A tricarbocyanine dye that is used diagnostically in liver function tests and to determine blood volume and cardiac output.

A infiltrating (invasive) breast cancer, relatively uncommon, accounting for only 5%-10% of breast tumors in most series. It is often an area of ill-defined thickening in the breast, in contrast to the dominant lump characteristic of ductal carcinoma. It is typically composed of small cells in a linear arrangement with a tendency to grow around ducts and lobules. There is likelihood of axillary nodal involvement with metastasis to meningeal and serosal surfaces. (DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1205)

A deoxycytidine derivative and fluorouracil PRODRUG that is used as an ANTINEOPLASTIC ANTIMETABOLITE in the treatment of COLON CANCER; BREAST CANCER and GASTRIC CANCER.
