ABSTRACT

ABSTRACT Objective To validate multilineage score system correlating results of flow cytometry, cytogenetics, cytomorphology and histology from samples of patients with suspected myelodysplastic syndrome or cytopenia of unknown origin. Methods A retrospective study analyzing laboratory data of 49 patients with suspected myelodysplastic syndrome or cytopenia of unknown origin, carried out between May and September 2017. The inclusion criteria were availability of flow cytometry results, and at least one more method, such as morphology, histology or cytogenetics. Thirty-eight patients were classified as diagnosis of myelodysplastic syndromes, whereas 11 were classified as normal. Patients were evaluated based on score systems, Ogata score and flow cytometry multilineage score. Results Comparing the scores obtained in the Ogata score and the multilineage score, it was observed that in four cases the Ogata score was zero or 1 point, while the multilineage score was higher than 3 points. In addition, in 12 cases with Ogata score of 2, the multilineage score was greater than 3. Conclusion The flow cytometry multilineage score system demonstrated to be more effective in dysplasia analysis, by assessing the erythroid, monocytic, granulocytic and precursor cell lineages, apart from the parameters evaluated by the Ogata score.


RESUMO Objetivo Validar ficha de escore multilinhagem correlacionando resultados obtidos de citometria de fluxo, citogenética, citomorfologia e histologia de amostras de pacientes com suspeita de síndrome mielodisplásica ou citopenias a esclarecer. Métodos Estudo retrospectivo de análise de dados laboratoriais de 49 pacientes com suspeita clínica de síndrome mielodisplásica ou citopenias a esclarecer realizado entre maio e setembro de 2017. Os critérios de inclusão foram a disponibilidade de resultados de citometria de fluxo e de, pelo menos, outra metodologia, entre morfologia, histologia, ou citogenética. Trinta e oito pacientes foram classificados como diagnosticados com síndromes mielodisplásicas enquanto 11 foram classificados como normais. Os pacientes foram avaliados utilizando sistemas de escore, escore de Ogata e ficha multilinhagem. Resultados Comparando as pontuações obtidas no escore de Ogata e na ficha multilinhagem, observou-se que, em quatro casos, o score de Ogata foi zero ou 1 ponto, enquanto, pela ficha multilinhagem, a pontuação foi superior a 3 pontos. Além disso, em 12 casos com escore de Ogata 2, a pontuação pela ficha multilinhagem foi superior a 3. Conclusão A ficha multilinhagem demonstrou ser mais eficaz na análise de displasia por avaliar as linhagens eritroide, monocítica, granulocítica e células precursoras, além dos parâmetros avaliados no escore de Ogata.
