Purpose
RATIONALE: Diagnostic procedures, such as lymphoscintigraphy using an injection under the nipple or near the tumor, may help doctors find out how far the disease has spread.
PURPOSE: This clinical trial is studying two different injection methods to compare how well they find the sentinel lymph node during lymphatic mapping and sentinel lymph node biopsy in patients with invasive breast cancer.

Experimental: Injection Methods
One injection site with radioactive tracer intraparenchymal/peritumoral (around the tumor), and other subareolar (around the nipple)
|
Drug: Isosulfan Blue
At time of surgery, breast injected with 3-5 cc of isosulfan blue in subareolar or peritumoral position.
Other Name: lymphazurin
Procedure: Lymphangiography
2 lymphoscintigraphy images performed following peritumoral and subareolar injection of breast
Radiation: Technetium Tc 99m sulfur colloid
At least 2 days before scheduled surgery, receive technetium Tc 99m sulfur colloid by peritumoral injection; and again the day before surgery by subareolar injection. At the time of surgery, patients receive isosulfan blue by subareolar injection. |
Detailed Description:
OBJECTIVES:
- Compare subareolar injection with peritumoral injection in identifying the sentinel node during breast lymphatic mapping in patients with invasive breast cancer.
- Compare the lymphatic drainage patterns using lymphoscintigraphy of the breast with subareolar injection vs peritumoral injection.
OUTLINE: At least 2 days before scheduled surgery, patients receive technetium Tc 99m sulfur colloid by peritumoral injection followed by lymphoscintigraphy. Images are obtained at 30 minutes and after 2 and 3 hours, provided no drainage is noted. Patients then receive technetium Tc 99m sulfur colloid by subareolar injection followed by another lymphoscintigraphy.
At the time of surgery, patients receive isosulfan blue by subareolar injection. A handheld gamma probe is used to locate the sentinel node. If the sentinel node is identified, it is excised and the scheduled breast surgery is performed. If the sentinel node cannot be identified, patients undergo the scheduled breast surgery.
PROJECTED ACCRUAL: A total of 100 patients will be accrued for this study within 12.5 months.
Eligibility| Genders Eligible for Study: | Both |
| Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Patients must have either pathologic, radiologic or clinical evidence of breast cancer with invasion, suspicious for invasion or microinvasion.
- Patients who are candidates for a total mastectomy or segmental mastectomy or axillary dissection.
- Patients who have undergone neoadjuvant chemotherapy who have an FNA confirmed lymph node positive for metastatic disease prior to induction chemotherapy and are then found to have grossly palpable disease but are ultrasound node negative at time of study entry.
- Patients must sign an informed consent and be registered before the procedure is performed.
Exclusion Criteria:
- A pregnancy test will be required preoperatively in women of childbearing potential and patients who are pregnant will be excluded from this study.
