A 60-year-old woman has a firm mass with irregular borders felt in her left breast on a routine physical examination. A fine needle aspiration is performed and microscopic examination shows an infiltrating ductal carcinoma. A left mastectomy with axillary lymph node dissection is performed. A tissue sample of this neoplasm is submitted for analysis by flow cytometry. Which of the following does flow cytometric analysis most likely provide?

A Determination of the karyotype

B Diagnosis of benign neoplasms

C Determination of aneuploidy

D Distinguishing carcinoma from sarcoma

E Quantitation of RNA content

(C) CORRECT. Flow cytometry can detect the degree of aneuploidy from the DNA content. Aneuploidy implies that the neoplasm is worse than if it were not aneuploid.nodnodnod

(A) Incorrect. Flow cytometry does not distinguish individual chromosomes or count them.
(B) Incorrect. Flow cytometry cannot be used to distinguish a benign from a malignant neoplasm.
(D) Incorrect. Flow cytometry cannot distinguish the cell of origin of neoplasms.
(E) Incorrect. Flow cytometry is used to measure DNA content.
