ABSTRACT
OBJECTIVE@#To study the correlation of hematomorphology, bone marrow cytogenetics and clinical biochemical parameters with the prognosis of non-Hodgkin's lymphoma with bone marrow invasion.@*METHODS@#Morphological analysis of bone marrow cells was performed by routine bone marrow puncture.Chromosome samples were prepared by short-term bone marrow culture. Karyotype analysis was carried out by R-banding in 28 patients. P53 gene was detected by fluorescence in situ hybridization (FISH). Serum lactate dehydrogenase (LDH) of all patients was determined and compared.@*RESULTS@#In all patients, bone marrow morphology showed invasion of lymphoma. Chromosome analysis revealed abnormal karyotypes in 19 cases, which yielded an incidence of 67.85%. The proportion of lymphoma cells in bone marrow among those with an abnormal karyotype was much higher than those with a normal karyotype (60.2% vs. 33.5%, P<0.05). FISH assay showed that 9 (32.14%) patients had P53 gene deletion. And the deletion was much more common among those with an abnormal karyotype (42.11% vs. 11.11%, P<0.05). The serum LDH level in patients with an abnormal karyotype was significantly higher compared with whose with a normal karyotype (1464.37 U/L vs. 294.33 U/L, P<0.05).@*CONCLUSION@#Patients with abnormal karyotypes have a higher rate of P53 gene deletion, and their LDH level is significantly higher than those with a normal karyotype, which predicted a relatively poor prognosis.
