The purpose of this study is to evaluate the biodistribution and dosimetry of single dose of 99mTc-glycopeptide (99mTc-GP, 20-25 mCi) in 3 different doses of GP (5, 10and 20 mg)in patients with breast cancer at pre-chemotherapy.
Cohorts of 3 will be treated each at different dose levels and images will be taken at 4 time points. For dosimetry estimates, there will be a 20-24 hr time point post-administration of 99mTc-GP for the first 3 patients. If the biodistribution and dosimetry can be adequately quantified without the 20-24 hr scan in 3 patients, then we will eliminate that 4th scan for all other patients. Urine and blood samples will be collected at 5 time points, and an additional blood and urine sample will be collected for dosimetry analysis at 30~60 min.

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 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.
Carbohydrate antigen elevated in patients with tumors of the breast, ovary, lung, and prostate as well as other disorders. The mucin is expressed normally by most glandular epithelia but shows particularly increased expression in the breast at lactation and in malignancy. It is thus an established serum marker for breast cancer.
