研究概览
简要总结
The goal of this clinical research study is to find lymph nodes before surgery using a dye called indocyanine green (IC-Green).
Objectives:
- 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.
- 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.
详细描述
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.
These 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 use an experimental camera that shines a special red light onto your skin causing the IC-Green to glow when the images are taken. 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. A study staff member will call you the next day and ask you to take your temperature. This phone call should last about 5 minutes.

入选标准
- •Subjects must be 18 years of age or older
- •Diagnosis of breast cancer requiring axillary nodal dissection
- •Negative urine pregnancy test within 72 hours prior to study drug administration, if female of childbearing potential
- •Females of childbearing potential who agree to use a medically accepted method of contraception for a period of one month following the study. Medically acceptable contraceptives include (i) hormonal contraceptives (such as birth control pills, Depo-Provera, or Lupron Depot) if such use is approved by the subject's Oncologist; (ii) barrier methods (such as a condom or diaphragm) used with a spermicide, or (iii) an intrauterine device (IUD).
- •Continuation of Inclusion #4: Non-childbearing potential is defined as physiologically incapable of becoming pregnant, including any female who is post-menopausal; postmenopausal is defined as the time after which a woman has experienced 12 consecutive months of amenorrhea (lack of menstruation).
- •Patients with a positive fine needle aspirate or core biopsy of their axillary nodes
排除标准
- •Women who are pregnant or breast-feeding
- •Persons who are allergic to iodine
- •A female of child-bearing potential who does not agree to use an approved contraceptive for one month after study participation
- •History of ipsilateral axillary surgery including sentinel node biopsy
- •Any patient who does not meet inclusion criteria for study
