Evaluation of bone marrow biopsy and smear examinations in differential diagnosis for patients with pancytopenia by simultaneously compartive study / 中国实验血液学杂志

To simultaneously compare and evaluate the examinations of bone marrow smear and trephine biopsy in differential diagnosis and therapeutical effect of pancytopenia patients, the differences between bone marrow smear and trephine biopsy in degree of cellularity, misdiagnosis rate and therapeutical effect for 71 patients with pancytopenia were analyzed. The results showed that the degree of cellularity in bone marrow biopsy for cytologic morphology was higher than that from the smear, but misdiagnosis rate in the biopsy was lower than that in the smear. In conclusion, bone marrow biopsy is necessary to the differential diagnosis and more valuable for evaluation of therapeutical effect and prognosis of pancytopenia patients.
