We analyzed the patterns of DNA ploidy in 31 colorectal carcinoid tumors from paraffin-embedded tissues by DNA flow cytometry and the relationship of the patterns of DNA ploidy to prognosis. Diploid DNA was found in 78% (24 of 31) of carcinoids and tetraploid in 6% (2 of 31). Five (16%) carcinoids were DNA aneuploid, and four of the patients with aneuploidy showing a near-hypertriploid pattern died during the first 5 years of follow-up. The association of aneuploidy with stage, size, and invasion of tumor was significant. However, our data indicated that DNA aneuploidy of a near-hypertriploid pattern was the most precise and reliable parameter for predicting the prognosis of colorectal carcinoid tumors.
