Abstract
Biological samples of mammary fluid or components thereof are obtained using a breast pump device coupled with an absorbent paper or membrane, optionally facilitated by administering oxytocin to the subject. The breast pump device stimulates expression of mammary fluid and provides for collection of diagnostic samples on the absorbent paper or membrane to evaluate breast disease, including cancer. The biological sample may include fluid containing one or more of cells or cellular components, proteins, glycoproteins, peptides, nucleotides or other desired constituents comprising a breast disease marker. Absorbent paper or membrane, and methods relating to the paper or membrane, and a breast pump device are also provided.
Claims26
-20. (canceled)
An absorbent paper that is sized to cover a nipple, comprising microcellulose, mixed cellulose ester paper or nitrocellulose, wherein the absorbent paper is from about 1.0 to about 3.0 inches in diameter and from about 0.01 to about 0.1 inches thick.
(canceled)
A method of identifying risk of developing breast cancer in an individual in need thereof, comprising:
- a) detecting the total amount of protein and/or number of cells in a nipple aspirate fluid sample absorbed onto an absorbent paper, wherein said absorbent paper comprises microcellulose, mixed cellulose ester paper or nitrocellulose;
- and
- b) identifying the risk for developing breast cancer based on the total amount of protein and/or the number of cells of the nipple aspirate fluid sample.
-34. (canceled)
A composition comprising nipple aspirate fluid (NAF) and an absorbent paper that is sized to cover a nipple, comprising microcellulose, mixed cellulose ester paper or nitrocellulose.
-47. (canceled)
A system for analyzing a nipple aspirate fluid (NAF) sample from an individual in need thereof comprising:
- a. an absorbent paper for absorbing the nipple aspirate fluid sample, the absorbent paper comprising microcellulose, mixed cellulose ester paper, or nitrocellulose, wherein the absorbent paper is sized to cover a nipple;
- and
- b. colloidal metal stain for determining the total protein of the nipple aspirate fluid sample.
