既往10年,急性白血病已取得治疗的进展,长期缓解率也相应增高,然而低增生性白血病仍为治疗上的难题。为此,作者从270例急性白血病中,对29例低增生型的临床和治疗方式作了探讨。骨髓增生程度依据髓液和颗粒涂片、骨髓活检及髓液离心定量计数作出全面判断。显著低下者,骨间隙为脂肪组织占据,造血成份<15%;中度低下者,造血细胞占据骨间隙的15～30%;轻度低下者,造血细胞占据骨髓的30～40%。29例骨髓活检均呈增 In the past 10 years, progress has been made in the treatment of acute leukemia, long-term response rate also increased accordingly, however, hypo-proliferative leukemia is still a treatment problem. To this end, the author from 270 cases of acute leukemia, 29 cases of low proliferative clinical and therapeutic approach were discussed. The degree of myeloproliferation is based on a comprehensive assessment of the medullary fluid and pellet smears, bone marrow biopsy, and quantitative quantification of the medullary fluid centrifugation. Significantly lower, the bone space occupied by adipose tissue, hematopoietic components <15%; moderately low, hematopoietic cells account for 15 to 30% of the bone space; mildly low, hematopoietic cells account for 30 to 40% of bone marrow. 29 cases of bone marrow biopsy were increased
