    Author: Guan JH, Wang XN, Ma K.
    Journal: Zhongguo Shi Yan Xue Ye Xue Za Zhi; 2013 Aug; 21(4):1054-7. PubMed ID: 23998611.
    Abstract:
    This study was aimed to explore the value of one-step method of bone marrow aspiration and biopsy applied in diagnosis of the bone marrow metastatic cancer. The total of 46 cases of bone marrow metastatic cancer were analyzed retrospectively, and the results of the bone marrow smear and the bone marrow biopsies were compared. The results indicated that the success rate of one-step method of bone marrow aspiration and biopsy was 95.7%. Metastatic carcinoma cells in clumps or clusters with morphological changes were observed in the bone marrow biopsies of the 45 patients (97.8%), but the metastatic carcinoma cell clusters were observed only in bone marrow smears of the 25 patients (54.3%). There were mild to moderate hyperplasia of fibrous tissue in the patients with metastatic cancer. In addition to the 83.3% diagnostic rate of esophageal cancer, the rest diagnostic rate of bone marrow biopsy for metastatic carcinoma was 100%. The diagnostic rate of bone marrow smear for ovarian cancer, lung cancer, gastric cancer, thoracic tumor, sigmoid colon cancer, esophageal cancer and metastatic cancer of unknown primary cancers were 33.3%, 50%, 72.2%, 60%, 50%, 33.3% and 25%, respectively. The diagnostic rate of bone marrow biopsy was higher than that of bone marrow smear. It is concluded that the success rate of drawing specimen by one-step method of bone marrow aspiration and biopsy is high. The bone marrow biopsy is better than that of aspiration in diagnosis of metastatic cancer. Combining biopsy with aspiration can improve the accuracy of diagnosis.
