多发性骨髓瘤肾功能衰竭66例

目的：分析66例多发性骨髓瘤（MM）患者的特征、治疗反应和肾功能可逆性相关的因素及生存期。方法：对1992年2月至200年2月诊断的MM患者66例进行研究；统计学方法：生存率、中位生存时间的计算及生存曲线的绘制采用Kaplan-Meier方法，生存曲线的比较采用Log-Rank检验。所有统计学检验均以α=0．05为显著性水平。统计学计算使用SPSS9．0软件包在PentiumⅡ计算机上完成。结果：66例患者26例（39．4％）有肾功能不全。肾功能不全MM患者更多处于疾病的Ⅲ期。肾功能不全和正常的MM患者治疗反应无统计学差异 （P＝0．398）。53．8％的患者肾功能恢复正常。血清肌酐水平（＜354μmol/L)和肾功能不全的可逆性有关。肾功能恢复正常的中位生存期是24个月，而肾功能不全不可逆的患者是8个月（P＝0．02）。在多变量分析中，只有肌酐水平（P＝0．0469）和化疗反应（P＝0．0117）对预后有显著性统计学意义。结论：MM患者确诊时，39．4％有肾功能不全，可的肾功能不全比不可逆的有更长生存期。肾功能恢复的相关因素是肾功能不全的程度、高钙血症。治疗反应与肾功能不全的严重程度是影响MM患者生存的独立因素。     

sBCMA在初诊多发性骨髓瘤患者中的表达水平及其与预后的关系

目的：研究可溶性B细胞成熟抗原（sBCMA）在多发性骨髓瘤（MM）患者外周血中的表达水平，并探讨其与MM患者预后的相关性。方法：收集31例初诊MM患者和30例健康志愿者的外周血，采用酶联免疫吸附试验（ELISA）法检测外周血中的sBCMA水平，并分析sBCMA水平与MM患者预后的相关性。结果：初诊MM患者外周血中sBCMA水平较健康对照组显著升高（P<0.05）。sBCMA水平与骨髓中浆细胞比例、M蛋白水平及治疗密切相关（P<0.05）。sBCMA水平与MM患者总生存期（OS）呈负相关(r=-0.47),sBCMA低表达的MM患者较sBCMA高表达患者OS显著延长（P<0.05）。结论：sBCMA在MM患者中显著升高，有望作为评估MM患者疗效以及预后的一种新指标。通过靶向sBCMA，可能为MM的治疗提供新的思路。

Thalidomide for patients with relapsed multiple myeloma after high-dose chemotherapy and stem cell transplantation: results of an open-label multicenter phase 2 study of efficacy, toxicity, and biological activity

OBJECTIVES: To determine the progression-free survival at 12 weeks, to evaluate the toxic effects, and to analyze the biological activity of thalidomide in patients with relapsed multiple myeloma (MM) after high-dose chemotherapy and stem cell transplantation. PATIENTS AND METHODS: From 1999 to 2001, we performed a multicenter prospective phase 2 study in patients with MM that relapsed after high-dose chemotherapy and stem cell transplantation to evaluate the efficacy of oral thalidomide, with dose escalation from 200 to 600 mg/d over 12 weeks and a subsequent maintenance phase of 200 mg/d for up to 1 year. Outcome was correlated with serum and plasma levels of vascular endothelial growth factor and serum levels of tumor necrosis factor alpha, soluble intercellular adhesion molecule 1, interferon gamma, interleukin (IL) 2, and IL-6 during treatment. RESULTS: Thirty patients were treated (19 men and 11 women; median age, 58 years). The median number of prior therapies was 5, and the median duration from diagnosis of MM to study enrollment was 4.3 years. The 12-week progression-free survival rate was 67% (95% confidence interval [CI], 48%-86%). The observed response rate (partial response plus minor response) was 43% (95% CI, 28%-60%) with a median duration of 6 months. Attributable toxicities included constipation, fatigue, rash, and neuropathy, which was dose limiting in 8 patients (27%). Dose escalation from 200 to 600 mg/d was achieved in 50% of patients. Although responses were observed with lower doses, possibly eliminating the need to escalate the dose, responses were also seen in patients who completed the dose escalation. Some patients had disease progression while receiving the maintenance dose of 200 mg/d. Analysis of biomarker assays did not identify any biomarker associated with greater response, but a significant increase in levels of soluble intercellular adhesion molecule 1, IL-2, and interferon gamma was seen with thalidomide therapy. CONCLUSION: The optimal thalidomide dose varies, and adverse effects can be dose limiting. The dose of thalidomide therapy should be based on the individual patient to ensure that it is well tolerated and that a response is achieved.

恶性淋巴增殖性疾病患者血清可溶性细胞间粘附分子—1的检

OBJECTIVE: To investigate the correlation of serum levels of soluble intercellular adhesion molecule 1 (sICAM-1) with clinical situation and treatment outcome in lymphoproliferative disorders. METHODS: Serum sICAM-1 levels were measured by immunoenzymatic assay. RESULTS: Pre-treatment serum sICAM-1 levels were above normal in 41% (9/22) of multiple myeloma (MM), 53% (17/32) of non-Hodgkin's lymphoma (NHL) and 63% (12/19) of acute lymphocytic leukemia (ALL) patients. Serum sICAM-1 levels in MM were positively correlated with Bataille stages, but were not related to Durie stage. Meanwhile, sICAM-1 levels in NHL were associated with the category of pathology, Ann Arbor stage and B symptom, but were not related to serum LDH levels. sICAM-1 levels were significantly higher in ALL patients complicated with central nervous system leukemia (CNSL) than in those without CNSL. Patients with elevated serum sICAM-1 levels had poorer treatment outcomes. Serum sICAM-1 levels were returned to normal at remission. CONCLUSION: Measurement of serum sICAM-1 levels in lymphoproliferative disorders patients is helpful for judging the clinical status and treatment outcome.     

112例多发性骨髓瘤患者ISS分期分析及与DS分期、IFM分期的比较

目的 探讨国际分期体系(ISS)在我国多发性骨髓瘤(MM)患者中的适用性,并与Durie-Salmon(DS)分期、法国骨髓瘤工作组(IFM)分期进行比较.方法 对112例具有ISS分期资料的MM初诊患者进行回顾性分析.结果 ①预后因素:血清β2微球蛋白(β2-MG)1≥3.5 mg/L是患者总体生存(OS)时间的独立预后不良因素,血清白蛋白(ALB)＜35g/L是患者疾病进展时间(TTP)的独立预后不良因素;在有核型检测结果 的58例患者中,13号染色体异常(△13)是OS时间的唯一独立预后不良因素;②临床指标相关性:与血清β2-MG显著相关的因素有血清肌酐、24 h尿蛋白定量、体重指数(BMI)、体能分级(PS);与血清ALB显著相关的因素有血红蛋白浓度、骨髓浆细胞比例、乳酸脱氢酶(LDH)、发热、PS、M蛋白类型、血清磷、BMI;⑧ISS分期临床特征:除血清β2-MG和肌酐外,其他传统预后指标在Ⅱ、Ⅲ期间的差异无统计学意义;6例△13阳性患者中5例划入ISSⅡ期;④预后效能比较:ISS分期中Ⅰ、Ⅱ、Ⅲ期患者的中位OS时间分别为69、23和26个月,其中Ⅱ、Ⅲ期间差异无统计学意义;DS分期中89.5%的患者被归人Ⅲ期,Ⅰ、Ⅱ期与Ⅲ期间预后差异无统计学意义;IFM分期中低、中、高危三组患者的中位OS时间依次为69、40和8个月,其中低、中危组与高危组间差异有统计学意义.结论 ISS分期体系Ⅱ、Ⅲ期的划分似乎并不适用于中国MM患者;ISS、DS、IFM三个分期体系比较后发现纳入遗传学指标△13的IFM体系区分预后效能最佳.

Clinical course of patients with relapsed multiple myeloma

OBJECTIVE: To study the clinical course of patients with multiple myeloma (MM) that relapses after initial therapy. PATIENTS AND METHODS: Patients with MM, seen at the Mayo Clinic in Rochester, Minn, between January 1, 1985, and December 31, 1998, were identified from a prospectively maintained database. Our study population consisted of 578 patients with newly diagnosed MM who were followed up and monitored throughout their clinical course at our institution. RESULTS: The median age of the 578 patients with MM was 65 years (range, 26-92 years); 228 patients (39%) were women. The median follow-up of 71 surviving patients was 55 months (range, 0-202 months). The overall survival (OS) for the 578 patients at 1, 2, and 5 years was 72%, 55%, and 22%, respectively; the median OS from initial therapy was 28.4 months. The median OS of 355 patients who experienced relapse after initial treatment was 17.1 months from initiation of the second therapy, and 84% died within 5 years. The duration of response decreased consistently with each successive regimen. Patients with a high plasma cell labeling index (> or = 1.0%), low platelet count (< 150 x 10(9)/L), high creatinine level (> or = 2.0 mg/dL), and low albumin level (< 3.0 g/dL) had a poorer prognosis. CONCLUSIONS: Our study revealed decreasing response duration with increasing number of salvage regimens, probably reflecting acquired drug resistance and an increasing proliferative rate of the myeloma cells. Patients who experienced relapse after initial treatment and received salvage therapy had a median survival of nearly 1.5 years. This must be remembered when making treatment decisions for these patients and must be factored in when assessing the efficacy of new therapies.     

Serum β2-microglobulin levels in multiple myeloma and monoclonal gammapathy of undetermined significance: A clinical study of 55 patients

Summary Previous reports provided clear evidence that serum β₂-microglobulin (β2m) is a marker highly correlated with the total mass of myeloma cells and suggested its use in the follow-up of patients with plasma cell tumors. Serum β2m levels were measured in 38 patients with multiple myeloma (MM), in 17 patients with monoclonal gammapathy of undetermined significance (MGUS) and in 32 normal control subjects. While statistically significant differences could be established between controls and both MM and MGUS patients, between patients with MM at stage III and patients with MM at lower stages as well as between patients with MGUS and patients with mostly advanced MM, it was not possible to statistically separate patients with MM at stage I from patients with MM at stage II, patients with untreated MM from patients with treated MM and, finally, patients with MGUS from patients with low cell mass MM. These results substantially confirm the already published data and lead to the conclusion that serum β2m determination is a useful test in the clinical management of monoclonal gammapathies, but it does not allow a differential diagnosis between benign and malignant forms of the disease.

目的 探讨不同的治疗方案[BD(硼替佐米+地塞米松)、TID(沙利度胺+地塞米松)]对多发性骨髓瘤(MM)骨病的影响.方法 2006年11月至2008年9月,分别应用硼替佐米和沙利度胺联合地塞米松治疗的初治及难治复发MM患者共40例.在2种不同化疗方案前后,对患者进行骨痛评分、X线检查,同时采用ELISA法检测血清成骨细胞抑制因子DKK-1、可溶性细胞核因子κB受体活化因子配体(sRANKL)和抗酒石酸酸性磷酸酶(TRACP)-5b等骨代谢因子的水平.结果 TD组治疗前后中位血清TRACP-5b水平分别为5.94 U/L和4.84 U/L(P＜0.05).BD组有效患者治疗前后中位血清DKK-1浓度分别为35.11 μg/L和32.03 μg/L(P＜0.05);血清sRANKL浓度分别为1.05 pmol/L和0.67 pmol/L(P＜0.05);血清TRACP-5b浓度分别为5.57 U/L和4.90U/L(P＜0.05).结论 硼替佐米治疗有效的患者通过下调血清DKK-1、sRANKL和TRACP-5b水平从而可能显著增加骨形成活动,减少骨吸收活动;沙利度胺治疗的患者骨吸收活动显著减少.

Abstract：

Objective To explore the difference of effects of two regimens (bortezomib and dexamethasone, BD; and thalidomide and dexamethasone, TD) on bone disease in multiple myeloma(MM).Methods Forty patients with newly diagnosed and refractory or relapsed MM were treated with BD or TD regimens from Dec 2006 to Sep 2008. Bone pain score and X-ray examination were carried out before and after therapy. Serum levels of DKK-1, sRANKL, OPG and TRACP-5b were measured by ELISA before and 3 months after therapy. Results Serum TRACP-5b concentration was significantly decreased in patients received TD regimen (5.94 U/L before therapy vs 4.84 U/L 3 months after therapy ,P ＜ 0.05), and so did for serum DKK-1 concentration in patients responded to BD regimen (35.11 μg/L before vs 32.03 μg/L 3 months after therapy,P ＜0.05) ;for serum concentration of sRANKL in patients responded to BD regimen (1.05 pmol/L before vs 0.67 pmol/L 3 months after therapy, P ＜ 0. 05); and for serum concentration of TRACP-5b in responders to BD regimen (5.57 U/L before therapy vs 4.90 U/L 3 months after therapy ,P ＜0.05). Conclusion Bortezomib lowers levels of serum DKK-1 and RANKL in responders, thus leads to normalization of abnormal bone remodeling through the increase of bone formation and reduction of bone resorption. Thalidomide decreases bone resorption regardless of treatmant response.
