Objective:Bone metastases and haematological symptomes are sometimes the first manifestation of carcinoma.The present study aimed to reveal the clinical characteristics of bone marrow metastatic carcinoma;to improve the recognition of metastatic carcinoma of bone marrow;to treat patients effectively;to prolong patient's survival time;and to raise life quality of those patients.Methods:The clinical data of 62 patients with bone metastases were obtained and analyzed from 1995 to 2008.Clinical manifestation,hemogram and bone marrow picture were summarized in these patients with bone metastases.Results:Haematological symptomes were first symptoms in 62 patients with bone metastases.Amony them,the primary location of carcinoma was eventually identified in 51 patients.The average survival time was(11.16±7.72)months.The most common symptom was bone pain,followed by anemia(90.3%,56/62),fever(62.9%,39/62)and bleeding(37.1%,23/62).71.4% of patients with anemia showed normochromic anemia.White blood cell count was normal in 12 patients(19.4%),increased in 39 patients(62.9%),decreased in 11 patients(17.7%).bone marrow examination indicated that proliferation of nucleated cells active was presented in 35 patients(56.5%),hyperplasia to reduce in 12 patients(19.4%),bone marrow stem smoking in 15 patients(24.2%).The impact factors of life span included the proliferation degree ofone nucleus pulposus cells,the hemoglobin,melts,the chemoradiotherapy and the hemorrhage.Conclusions:When aematological symptomes as the first manifestation were presented in patients,the diagnosis of bone marrow metastasis should be considered.The bone marrow aspiration or bone marrow biopsy should be performed timely.
