目的　研究骨髓转移癌的临床及血液学特点。方法　骨髓活检塑料包埋切片 ,H Gmiesa E ,Gomori ,PAS ,Alcinblue染色。结果　 47例患者中 2 4例找到原发灶 ,其中胃癌 15例 ,前列腺癌 4例 ,肺癌 2例 ,乳腺癌、结肠癌、肝癌各 1例。 3 4例做骨髓活检者骨髓均找到转移癌细胞 ,而其中 10例骨髓象未能发现转移癌细胞。临床表现以贫血最常见 (91.5 % ) ,其次是血小板减少 (64 .7% )、骨痛 (61.7% )和发热 (4 8.9% )。结论　对于不明原因的贫血和骨痛患者 ,骨髓活检对转移癌具有重要诊断价值 Objective To study the clinical and hematological features of bone marrow metastases. Methods Bone marrow biopsy plastic embedded sections, H Gmiesa E, Gomori, PAS, Alcinblue staining. Results Of the 47 patients, 24 cases found primary tumor, including 15 cases of gastric cancer, 4 cases of prostate cancer, 2 cases of lung cancer, 1 case of breast cancer, colon cancer and liver cancer. 34 cases of bone marrow biopsy were found in bone marrow metastatic cancer cells, and 10 cases of bone marrow like failed to find metastatic cancer cells. The most common clinical manifestations were anemia (91.5%), followed by thrombocytopenia (64.7%), bone pain (61.7%) and fever (4. 8.9%). Conclusion In patients with unexplained anemia and bone pain, bone marrow biopsy has an important diagnostic value for metastatic cancer
