Comments:
DNA ploidy analysis provides correlative information of use in the staging of tumors. Ploidy analysis provides indication of whether a tumor has a normal component of chromosomes (diploid) or an abnormal number (aneuploid). The percentage of cells which are in active growth (S-phase) can also be enumerated. Generally, tumors which are aneuploid and have high S-phase percentages behave more aggressively.
Rejection Criteria:
Insufficient cells for analysis; excessive necrosis and debris.
