目的：研究以血小板计数增多发病的慢性粒细胞白血病的临床表现与生物学特点。方法对患者外周血细胞形态、骨髓细胞形态、染色体、融合基因进行检查。结果以血小板计数增多发病的慢性粒细胞白血病的临床发病率低，易误诊为原发性血小板增多症，可检测到bcr/abl融合基因及Ph染色体，随病程进展，可进一步向加速期、急变期演变，应及早干预。结论对于以血小板计数增多发病的患者，应注意检测bcr/abl融合基因及Ph染色体，鉴别慢性粒细胞白血病与原发性血小板增多症，以避免误诊、误治。

Objective To study the clinical and biological characteristics of chronic myeloid leukemia(CML) with thrombocytosis.Methods The changes of patients were observed by blood films, bone marrow smear and biopsy. The bcr/abl fusion gene was examined by reverse transcription-polymerase chain reaction assay. The genetic changes of the cells were determined by conventional chromosome analysis. Result The patients of chronic myeloid leukemia with thrombocytosis were very rare and might be misdiagnosed as essential thrombocythemia. The bcr/abl fusion gene and the Ph chromosome were examined in the patints,and they could develop into accelerated phrase or blast crises of CML.So ealier intervetion is necessary. Conclusion CML with marked thrombocythemic onset has unique clinical and biological charactoristics. It is necessary to diffentiate ET and CML by examining the bcr/abl fusion gene and the Ph chromosome in order to avoid diagnosing and treating incorrectly.
