Logistic regression analysis of small round cell neoplasms: A cytologic study

摘要: The diagnosis of small round cell neoplasms (SRCN) in children is difficult by both histologic and cytologic methods. These are unified morphologically the scanty cytoplasm surrounding relatively nuclei containing a primitive chromatin pattern. Further categorization achieved histologically recognition architectural differentiation cytoplasmic features. Numerous series case reports documenting features SRCN have been published English-language literature, but few studies statistically analyzed diagnostic utility these Our logistic regression analysis 59 cases indicates that presence an extremely favors Ewing's sarcoma (P = 0.004), as does positive expression vacuoles 0.02).
