ABSTRACT
143 cytological studies of the material obtained from 98 children aged from 2 to 18 years with tentative diagnosis of Ewing's sarcoma were made. Histocytological correlations showed 96.2% cases to be of informative value, 87% of them with precise cytological diagnosis of the above sarcoma. The analysis of images specified mean values of square (S) and ploidity (P) of tumor cell nuclei in 21 children with a good (10), and bad (11) outcome of the disease. It was established that if ploidy is higher than expected one (p = 0.0357 S), bad prognosis can be supposed and a good prognosis in the opposite case. In case of good prognosis differentiated tumor cells with large clear nuclei are seen in the smears, and poorly differentiated cells with hyperchromic nuclei are observed in cases with bad prognosis.
