BACKGROUND: We analyzed the histological features and DNA flow cytometric results in 34 @entity1 with @entity1911 and @entity1823 and attempted correlation with the biological behavior for determination of the malignant potential of these @entity5 . METHODS: DNA analysis was done on a FACSort flow cytometer using paraffin-embedded tissues. Histopathological analysis was performed using parameters, i.e., cell size (large, medium, and small), cell size variation, mitotic rate, nuclear pleomorphism, golden yellow to brown pigment in the @entity5 , @entity39 , and @entity3 . RESULTS: Six @entity5 had high (>5/10HPF) mitotic rate while @entity3 was seen in three @entity5 . Fifty percent (18/34) of @entity1 had @entity5 , and 68% (23/34) of @entity1 had high (>10%) S-phase fraction @entity5 . Aneuploidy correlated with >5/10HPF mitotic rate (P <.05) and diploidy with golden yellow to brown pigment (P <.01). The @entity1 with @entity5 had a worse prognosis than @entity1 with @entity5 (P =.004). No such difference was observed with low and high S-phase fractions (P =.748), presence and absence of @entity3 (P =.927), and mitotic rate (P =.159). Nuclear pleomorphism and @entity39 were not significant factors in prognosis. CONCLUSIONS: Flow cytometric DNA analysis of @entity1823 and @entity1911 correlated with biological behavior in the @entity1 with regard to metastasis and overall survival in the @entity1 .
