恶性淋巴瘤骨髓侵犯相关因素分析

目的 探讨恶性淋巴瘤骨髓侵犯的相关因素。方法分析恶性淋巴瘤骨髓侵犯57例初治患者的临床资料。结果恶性淋巴瘤骨髓侵犯与患者的年龄、病理类型、临床分期、受累部位、有无全身症状、病程等有关，年龄以30岁以下为多(50％)，病理类型以小淋巴细胞型及弥漫型裂细胞、淋巴母细胞、大细胞多见(84％)，临床分期以Ⅲ期、Ⅳ期为多(95％)，受累部位以纵隔及脾脏为多(44％、32％)，有全身症状者占63％，平均病程4．5月，45例NHL骨髓侵犯(BMI)患者仅有3例外周血象异常。结论恶性淋巴瘤患者年轻、病理类型差、临床分期晚、纵隔及脾脏受累、有全身症状、病程长者易出现骨髓侵犯，但BMI患者外周血象不能提示骨髓侵犯。为正确分期和指导临床治疗，应常规行骨髓涂片检查。

淋巴瘤侵犯骨髓的骨髓活检病理学诊断研究进展

淋巴瘤侵犯骨髓(lymphomabonemarrowinvolvement,LBMI)主要靠骨髓活检确诊。霍奇金淋巴瘤(Hodgkin蒺slymphoma,HL)、非霍奇金淋巴瘤(non-Hodgkin蒺slymphoma,NHL)侵犯骨髓各有其不同病理特点。骨髓中瘤细胞的形态特点、分布方式及免疫表型多数与髓外部位一致,少数又可存在差别。本文比较了各型HL、B-NHL、T-NHL的骨髓侵犯病理学特点,并从形态学、免疫组化及淋巴瘤基因重排检测三方面对LBMI的骨髓活检诊断研究进展进行了综述。

A Pilot Study of Autologous Bone Marrow Transplantation Followed by Recombinant Interleukin-2 in Malignant Lymphomas

In this study, we investigated the impact of recombinant interleukin-2 (rIL-2) after high dose chemotherapy and autologous bone marrow transplantation (ABMT) in 25 patients with refractory or relapsed Hodgkin's disease (HD) (11 patients) and non Hodgkin's lymphoma (NHL) (14 patients). 48% of patients had resistant disease, 84% achieved complete remission after ABMT. rIL-2 was started at a median of 54 days post-transplant and consisted of a first cycle of 5 days followed by 4 cycles of 2 days every other week. Patients received a mean of 160 × 10⁶ IU/m² rIL-2 and hematological toxicity was moderate and transient. None of the 5 evaluable patients with measurable disease responded to rIL-2. After a 5 year median follow-up, the probability of survival and DFS is 72% (HD: 73% and NHL: 70%, p = NS) and 45% (HD: 36% and NHL: 48%, p = NS) respectively. These somewhat encouraging results warrant further evaluation of rIL-2 after ABMT in controlled studies, especially in NHL patients stratified for previous chemosensitivity.

69例恶性淋巴瘤骨髓侵犯后骨髓象与血象分析

目的了解恶性淋巴瘤骨髓侵犯后骨髓与外周血白细胞之间的关系.方法对69例恶性淋巴瘤具有骨髓侵犯的骨髓细胞分类及外周血白细胞检验结果作回顾性分析.结果 69例恶性淋巴瘤骨髓侵犯者外周血白细胞计数异常33例,分类计数异常35例,骨髓增生正常者19例,增生异常者50例.结论当恶性淋巴瘤发展到骨髓侵犯或淋巴瘤细胞白血病时,外周血白细胞计数和分类计数与骨髓象之间没有绝对的对应关系,但如明确诊断为恶性淋巴瘤时则应把骨髓涂片细胞形态学列为常规检查,如其外周血白细胞形态出现异常,则应高度怀疑有淋巴瘤细胞白血病.     

Bone Marrow Involvement in Lymphoma: The Importance of Marrow Magnetic Resonance Imaging

Detection of bone marrow involvement is important for staging and treatment decisions in patients with lymphoma. Although routine bone marrow evaluation is based on aspirates and bone marrow biopsies, new diagnostic tools are required to improve diagnostic accuracy. Visual and quantitative assessment of the bone marrow by magnetic resonance (MR) imaging is useful for the detection of occult lymphomatous marrow involvement. MRI is also suitable for the evaluation of disease extent in the bone marrow. Furthermore, abnormal images on marrow MRI may be associated with a significantly poorer survival in patients with lymphoma, regardless of histologic findings in the marrow. Evaluation of the bone marrow by MRI is essential to assess disease status in patients with lymphoma.     

Magnetic resonance imaging of bone marrow versus bone marrow biopsy in malignant lymphoma

Bone marrow involvement is a frequent finding in malignant lymphoma. Bone marrow biopsy of the posterior iliac crest is routinely performed for staging. Abnormal magnetic resonance imaging (MRI) signals of bone marrow was also reported to be indicative of bone marrow involvement. This study included 60 patients with malignant lymphoma. Unilateral bone marrow biopsy of the posterior iliac crest was performed. MRI of lumbar spine was studied within 24 hours of bone marrow biopsy. 22 healthy controls were used for the detection of MRI objectivity during visual evaluation. In 83% of patients (50/60), biopsy and MRI results agreed completely. In two patients, histologic sections failed to show any evidence of bone marrow involvement despite abnormal MRI signals suggestive of involvement. In three patients, MRI was completely normal despite biopsy proven bone marrow infiltration. False negativity (3/60) and false positivity (2/60) rates were very low. Negative biopsy findings with positive or equivocal MRI results should not exclude bone marrow involvement and needs further evaluation with bilateral or guided biopsy. Thus, we conclude that MRI of bone marrow is a fairly sensitive, noninvasive modality and might be of potential value in detecting bone marrow infiltration in malignant lymphoid neoplasms which can be utilized as a useful adjunct to standard staging procedures.

Femoral marrow MRI is a non-invasive,non-irradiated and useful tool for detecting bone marrow involvement in non-Hodgkin lymphoma

Femoral marrow magnetic resonance imaging (MRI) is a non-invasive, non-irradiated and useful modality for evaluating bone marrow (BM) conditions. Human adult femoral BM is almost uniformly fatty marrow and has the largest volume of a single bone. MRI has an extremely high resolution for fat and water, which allows high-contrast imaging of cellular infiltration into fat tissue. In hematological diseases, femoral BM MRI can clearly detect cell infiltration, which is symmetrically imaged from the proximal to the distal direction of abnormal signal areas. Thus, we investigated the significance of femoral MRI for non-Hodgkin lymphoma (NHL). We analyzed the data of 69 NHL patients who received femoral MRI at diagnosis in this single-center retrospective cohort study. The median patient age was 73 years. MRI patterns were mainly classified as uniform patterns or nonuniform patterns. We also classified the range of cellular marrow as high-grade or low-grade based on whether it had spread to over half of the femur. Both overall survival (OS) and progression-free survival (PFS) were significantly influenced by abnormal femoral marrow MRI. In particular, the patients with cellular femoral marrow lesions had a worse OS and PFS based on log-rank tests. Multivariable analyses with the Cox proportional hazards model revealed that OS and PFS were significantly influenced by cellular marrow diagnosed by femoral MRI. We concluded that femoral marrow MRI is a useful tool for detecting BM involvement and an independent prognostic factor in NHL patients.     

Optimum trephine length in the assessment of bone marrow involvement in patients with diffuse large cell lymphoma.

BACKGROUND: The National Cancer Institute has recommended a bone marrow biopsy length of >/=20 mm for the staging and surveillance of patients with non-Hodgkin's lymphoma. However, there are few published data to support this recommendation, particularly the role of examining multiple levels. PATIENTS AND METHODS: Bone marrow biopsies from 172 patients with newly diagnosed diffuse large cell lymphoma (DLCL) entered in two consecutive trials of the Australasian Leukaemia and Lymphoma Group were analysed. The original haematoxylin and eosin-stained trephine biopsy and two or more deeper sections cut at 0.1-0.2 mm intervals were assessed with respect to the morphology, extent and pattern of lymphomatous involvement. The rate of positive diagnosis was correlated with the length of the biopsy specimen and the number of sections examined. RESULTS: Forty-seven biopsies (27%) demonstrated marrow involvement on examination of a mean of four trephine biopsy sections. The rate of positivity increased with the examination of multiple levels and correlated with increasing trephine length but was not dependent on the number of sites sampled. Twenty per cent of biopsies <20 mm in length were positive for lymphoma; this increased to 35% for biopsies >/=20 mm (P = 0.023). CONCLUSIONS: Morphological bone marrow involvement in DLCL is optimally demonstrated by a 20-mm long trephine biopsy from a single site which is examined at multiple levels (four or more). This obviates the need for bilateral sampling, thereby reducing patient morbidity from the procedure. This study provides evidence to support the National Cancer Institute recommendations regarding trephine biopsy in the staging of DLCL, providing multiple levels are examined.
