非霍奇金淋巴瘤组织中细胞间黏附分子-1表达的初步研究

 目的　探讨非霍奇金淋巴瘤（NHL）肿瘤组织中细胞间黏附分子-1（ICAM-1）的表达与疾病播散的相关性及其分泌机制。方法　用免疫组织化学方法检测50例NHL患者肿瘤组织中ICAM-1的表达。结果　31（62 %）例NHL患者的肿瘤细胞ICAM-1阳性表达。32（64 %）例NHL患者的血管内皮细胞ICAM-1阳性表达。病理类型以弥漫大B细胞和外周T细胞非特指型的ICAM-1为多见,阳性率达70 %以上。晚期和骨髓浸润的NHL患者肿瘤组织中ICAM-1为低表达。ICAM-1阳性和阴性二组NHL患者的OS率分别为74.2 %和47.4 %,二者差异较明显,但无统计学意义。对预后有一定提示作用。结论　NHL患者肿瘤组织ICAM-1的表达以成熟活性淋巴瘤细胞阳性率为高。表达低或阴性显示黏附功能低下,肿瘤细胞易扩散。ICAM-1产生的机制与肿瘤细胞自分泌和血管内皮细胞旁分泌有关。

评价全身FDG-PET/CT在诊断淋巴瘤患者骨髓浸润中的价值

目的:本研究旨在评价PET-CT和骨髓涂片、骨髓活检、免疫分型结果诊断淋巴瘤的一致性和相关性。方法:收集临床确诊淋巴瘤患者的详细临床信息,包括姓名、性别、年龄、淋巴瘤细胞起源、病理分型、临床分期、行为状态、有无B症状、血LDH水平、血β2微球蛋白水平、骨髓涂片结果、免疫分型结果、骨髓活检结果以及详细的PET-CT影像学描述等。根据不同临床信息为患者进行详细分层,评价影响PET-CT中骨髓摄取葡萄糖的因素、影响淋巴瘤骨髓浸润的因素。设定骨髓涂片、骨髓活检、免疫分型阳性为对照,探究PET-CT在诊断淋巴瘤患者骨髓浸润中的价值。分别探讨PET-CT对于诊断不同病理类型淋巴瘤患者骨髓浸润的差异。结果:在性别、病理类型、细胞起源、有无B症状及骨髓浸润等不同分层中,只有淋巴瘤骨髓浸润与PET-CT中骨髓葡萄糖摄取有密切相关性(P=0.002)。而骨髓浸润与年龄(P=0.017)密切相关。设定骨髓涂片、骨髓活检、免疫分型阳性为对照,PET-CT检测淋巴瘤总体骨髓浸润的敏感度为54.3％、特异度为80.5％、准确度为74.5％,并且在不同病理类型中差异显著。PET-CT可以与骨髓涂片、骨髓活检、免疫分型共同指导淋巴瘤临床分期。结论:PET-CT中的骨髓葡萄糖摄取对淋巴瘤骨髓浸润及临床分期有一定的指导意义。不同病理类型的淋巴瘤中,PET-CT与骨髓涂片、骨髓活检、免疫分型的一致性不尽相同。PET仍不能完全取代骨髓涂片、骨髓活检、免疫分型。     

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.     

Bone marrow scintigraphy using Technetium-99m antigranulocyte antibody in malignant lymphomas

Background: The purpose of this study was to elucidate the clinical reliability of immunoscintigraphy (IS) to detect infiltration of the bone marrow in patients with malignant lymphoma.Patients and methods: Whole body IS was performed in 103 patients with Hodgkin's disease (HD) or non-Hodgkin's lymphoma (NHL) using Tc-99m labelled anti-NCA-95 which allows visualization of the granulopoietic bone marrow. Of these, 52% were studied prior to any therapy. Findings were compared to posterior iliac crest biopsy as well as MRI and/or follow-up examination. Criteria of marrow infiltration were a positive biopsy, positive follow-up, or positive results of MRI.Results: Comparison of IS and biopsy revealed concordant findings in 69 and discordant findings in 34 of 103 patients. Of the 34 patients with discordant results, IS showed lesions suspicious of bone marrow infiltration in 29 patients despite normal biopsy findings. When follow-up and additional examinations were taken into consideration, 10 patients remained with probably false positive and five with false negative IS findings. IS proved to be highly sensitive and specific in patients with HD (100% and 84%, respectively) and high-grade NHL (93% and 84%, respectively). Moderate sensitivity (60%) was found in low-grade NHL. This was possibly due to false negative IS in three to five patients with chemotherapy in contrast to one of five false negative results in patients without chemotherapy.Conclusion: Bone marrow scintigraphy using antigranulocyte antibodies is highly sensitive in HD and high-grade NHL. Positive findings in IS subsequent to a negative biopsy should be followed by guided re-biopsy or MRI.     

Clinicopathological studies on bone marrow involvement of non-Hodgkin's lymphoma

OBJECTIVE: To investigate the relationship between pathomorphological features and clinical manifestations of non-Hodgkin's lymphoma (NHL) with bone marrow involvement (BMI). METHODS: Plastic-embedded section of bone marrow biopsy was stained with H-Giemsa-E. Immunotyping of NHL was performed immunohistochemically. RESULTS: A total of 70 patients with NHLBMI(male: 52, female: 18; median age: 49 years) was studied. There were 20 patients with T cell-lymphoma and 50 patients with B cell-lymphoma. The extent of bone marrow involvement was minimal in 15 cases, moderate in 16 cases and severe in 39 cases. Bone marrow involvement was of interstitial type in 23 cases, nodular type in 7 cases, and mixed type in 18 cases and diffuse type in 22 cases. The frequency of splenomegaly in nodular type NHLBMI was significantly higher than that in any other type. Nodular type NHLBMI occurred mainly in B cell-lymphoma. Lymphoma cell leukemia (LCL) developed in 14 of 39 (35.9%) cases of NHL with severe bone marrow involvement which was significantly more frequent than that in NHL with mild and moderate bone marrow involvement. CONCLUSION: Difference in the extent and pattern of bone marrow involvement in NHL is related to clinical manifestations. Bone marrow biopsy helps evaluate response to treatment.

Bone marrow staging of patients with non-Hodgkin lymphoma by flow cytometry: correlation with morphology

BACKGROUND: Immunophenotypic analysis is an established tool in the diagnosis and classification of many hematolymphoid disorders; however, the role of flow cytometry (FC) in detecting bone marrow involvement during the staging of non-Hodgkin lymphoma (NHL) has yet to be defined. METHODS: The authors retrospectively analyzed 157 staging and 70 restaging bone marrow biopsies on which morphologic and FC analyses were performed; these biopsies were taken from 195 consecutive patients. Bone marrow biopsies were blindly and independently reviewed and determined to be positive, negative, or suspicious for morphologic involvement by NHL, with disagreements settled by a third reviewer. A selected panel of monoclonal antibodies was used to determine whether bone marrow involvement was immunophenotypically positive (>5%), minimal (<5%), negative, or nondiagnostic. RESULTS: FC and morphology agreed in 78% of cases (178 of 227: 129 both negative, 49 both positive) and were discrepant in 22% (49 of 227). Seven percent (16 of 227) were morphologically positive but showed no evidence of disease on FC, whereas 12% (27 of 227) were positive by FC but had no morphologic involvement. Of the 162 morphologically negative or suspicious bone marrows, 27 were shown to be involved by FC, resulting in a false-negative detection rate of 17%. Most of these (22 of 27, 81%) had minimal detectable disease. Seven percent of Stage I and 26% of Stage II NHL cases with negative staging bone marrow morphologically were found to be involved by FC. CONCLUSIONS: Neither morphologic examination of bone marrow biopsy specimens nor FC alone is adequate to detect all cases of NHL with bone marrow involvement. FC is most sensitive for detecting minimal bone marrow lymphoma, whereas morphology will detect most cases in which involvement is >5%. Cases of early stage NHL with morphologically negative bone marrow could potentially be restaged as Stage IV on the basis of FC results. The clinical importance of minimal bone marrow involvement by NHL needs further evaluation.
