骨髓瘤分期和危险因素影响疗效和生存期的因素有肾功能、血消钙水平、感染、血红蛋白数、白细胞或血小板减少和机体功能状态。而血清白蛋白、尿酸和非轻链尿蛋白量对预后十分重要,因与瘤细胞负荷有密切关系。从瘤细胞蛋白产生率和 M 蛋白分解率可推算出瘤细胞数量。又根据骨损害、血红蛋白、血清钙和异常IgG 量同肿瘤负荷的回归方程式,提出骨髓瘤的分期 Myeloma staging and risk factors Factors influencing efficacy and survival include renal function, serum calcium levels, infection, hemoglobin counts, leukopenia or thrombocytopenia, and functional status of the body. Serum albumin, uric acid and non-light chain urine protein amount on the prognosis is very important, because of the tumor cell load are closely related. From the tumor cell protein production rate and M protein degradation rate can be calculated from the number of tumor cells. Based on the regression equations of bone damage, hemoglobin, serum calcium, and abnormal IgG levels with tumor burden, the stage of myeloma
