摘　　要：非肿瘤死亡患者尸检常见滤泡性淋巴瘤、前列腺癌、乳腺癌等休眠肿瘤，而血液系统恶性肿瘤细胞的休眠与疾病的发生、发展和治疗密切相关。休眠是生物在生存竞争中普遍采用的策略，作为体内新生物的肿瘤保留了这类基本性状。肿瘤休眠的机制是近年来备受关注的研究课题，不仅具有理论意义，而且对肿瘤防治有指导作用，可能开拓新的防治途径，有助于对“过度诊断”“过度治疗”进一步认识，为“精准医学”提供新线索。文章介绍了肿瘤休眠的细胞机制及免疫和血管生成调控机制，讨论其临床意义和应用前景，并展望了深入研究的可能途径，以期为血液系统恶性肿瘤的诊疗提供新线索。Dormant follicular lymphoma, prostate carcinoma and breast carcinoma are frequently detected by autopsy of non-tumor patients. Dormancy of malignant cells in hematopoietic malignancies is associated with genesis, development and treatment of these diseases. Dormancy is the universally applied strategy by living organism during survival competition. As the in vivo neoplasm, tumor cells keep this property. Recently, much attention has been paid to the mechanisms of tumor dormancy. These studies not only have theoretical significance, provide new ways for the prevention and treatment of tumors, but also help the understanding of ＂over-diagnosis＂, ＂over-treatment＂ and provide clues for ＂precise medicine＂. This paper reviewed cellular mechanism of tumor cell dormancy,immunological and vascular regulation of dormant tumors. The clinical significance,application of these mechanisms and direction of further study, which will provide new clues for the treatment of hematopoietic malignancies, were also discussed.
