We histologically and immunohistochemically studied 95 bone marrow (BM) reactive plasmacytoses. Ten biopsies from plasma cell myeloma (PCM) patients served as a control group. In addition, we studied 10 monoclonal gammopathy of undetermined significance (MGUS) cases. Histologically, plasmacytosis varied between 5% and 25% with an interstitial pattern of plasma cell (PC) distribution being characteristically displayed. Immunohistochemically, we did not find any CD56/NCAM nor cyclin D1 expression in all biopsies (95 of 95, 100%), not even a weak, doubtful one; PCs were all polyclonal and CD138 positive. On the contrary, myeloma-associated PCs showed monoclonality for κ- or λ- light chain and strong CD56/NCAM immunoreactivity (8 of 10, 80%); four of them were cyclin D1 positive. Osteoblasts exhibited similar CD56/NCAM expression in both groups. Our data confirm the diagnostic utility of CD56/NCAM in the phenotypic characterization of polyclonal plasma cells, suggesting an important role of this particular immunomarker in the BM trephine study of polyclonal versus neoplastic plasmacytic infiltrations.  相似文献

Progression of multiple myeloma (MM) from intramedullary to extramedullary sites heralds an aggressive phase of the disease but to the best of our knowledge, biologic factors have not been studied in paired biopsies from medullary and extramedullary sites. In this study, we immunostained paired bone marrow and extramedullary biopsies from 12 cases of MM for p53, CD56 and MIB-1 (proliferative index). In addition, 22 cases of extramedullary plasmacytoma (EMP) without bone marrow involvement were included as a control group. p53 nuclear accumulations were detected in myeloma cells derived from the extramedullary sites in 9 (75%) of the 12 cases, whereas only 1 of (8%) 12 bone marrow myeloma specimens expressed p53 (P = 0.003). p53 expression was also more prevalent in extramedullary sites of MM than EMP (75% vs. 18%, P = 0.003). There was no significant difference in CD56 expression between intramedullary and extramedullary MM (17% vs. 33%, P = 0.64), or between intramedullary MM and EMP (17% vs. 38%, P = 0.25). The MIB-1 proliferation index increased significantly as plasma cells migrated from the bone marrow microenvironment to extramedullary sites (P = 0.0001). Our data indicates that p53 nuclear expression but not CD56 expression, along with increased proliferation index is associated with disease progression from intramedullary to extramedullary sites in MM.  相似文献

Primary plasma cell leukaemia: a report of 18 cases   总被引:6,自引:0,他引:6  
Primary plasma cell leukaemia (P-PCL) is a variant of multiple myeloma (MM) first diagnosed in the leukemic phase, with >2000/mm(3) circulating plasma cells (PCs) and plasmacytosis >20% of the white cell count. We investigated the clinical characteristics, therapy, immunophenotype and prognosis factors of 18 patients. Common features at diagnosis were asthenia (seven patients), renal insufficiency (ten patients), bone pain (seven patients), splenomegaly or hepatomegaly (five patients). Hypercalcemia was present at diagnosis in seven patients and was the most potent poor prognosis factor (P<0.05). Most patients (16 out of 18) were treated with an anthracyclin containing regiment; complete remission was attained in one patient and partial remission in 11 patients while six patients had no response. The median survival time from diagnosis was 7 months (2--12, 95% confidence interval), but response to treatment had favorable predictive value (P<0.05). The PCs were usually positive for mature B-cell markers (PCA-1, CD38). They expressed integrins which may increase their binding to endothelial cells and thus participate in PCL physiopathology by favoring plasmocyte extramedullary spread.  相似文献

The biological significance of CD56 antigen expression in patients with acute promyelocytic leukemia (APL) has been under investigation. We investigated the clinical and biologic features of CD56+APL. In our series, CD56 antigen was positive in 4 of 28 (14%) APL patients. No differences were found regarding age, gender, performance status (PS), initial leukocyte and platelet counts, lactate dehydrogenase (LDH) and fibrinogen (Fbg) levels according to CD56 expression. CD34 antigen was co-expressed in 3 of the 4 patients with CD56+ APL, in contrast to 2 of the 24 patients with CD56- APL (P = .01). Extramedullary relapse occurred in 3 of the 4 patients with CD56+ APL, in contrast to none of the 24 patients with CD56- APL (P = .001). Median remission duration was 4 months in CD56+ APL and was not reached in CD56- APL. The CD56+ population had a shorter remission duration (P < .0001) and disease-free survival (P < .0001). In contrast, no difference was found in overall survival. These results suggested that CD56 expression was associated with the leukemogenetic mutation at the primitive hematopoietic progenitor cell level and extramedullary relapse in APL patients treated with ATRA and chemotherapy.  相似文献

Abstract For differentiating reactive plasmacytosis from clonal plasma cell neoplasms such as plasma cell myeloma (PCM), it is important to determine the expression of the cytoplasmic light chain accurately. Through retrospective analysis, we studied the cytoplasmic kappa/lambda ratio of CD138-positive plasma cells in bone marrow from 50 patients with PCM and 50 controls by immunohistological analysis. The percentage of cytoplasmic light chain immunoreactive cells out of the total plasma cell population was shown by a novel quantitative image analysis approach using an Aperio ScanScope CS and the Membrane v9 algorithm. PCM cells were distinguished from normal plasma cells by cut-off levels between 0.35 and 5.5, a sensitivity of 100% and a specificity of 98.0%. Detection of the cytoplasmic kappa/lambda ratio of CD138-positive plasma cells could be a useful tool for simple, efficient and accurate diagnosis of PCM.  相似文献

We evaluated the frequency and prognostic significance of extramedullary infiltrates (EMI) at presentation of acute myeloid leukemia (AML) in adult patients. Of 331 cases with de novo AML, 101(30.5%) had extramedullary infiltrates at diagnosis. The extramedullary manifestations included: lymphadenopathy, splenomegaly, hepatomegaly, gingival hypertrophy, skin infiltrates and involvement of central nervous system (CNS). Patients with EMI had a high initial WBC count and a high proportion of M4/M5 morphological variants. The complete remission rate (CR) with induction chemotherapy was lower in patients with EMI (P=0.0077) and their overall survival was also inferior (P=0.0017). Flow cytometric evaluation of the surface antigens expressed by the leukemic blasts for CD34, TdT, HLADR, CD7, CD19 and CD56 found that only CD56 expression was associated with EMI. The association of CD56 expression with lymphadenopathy was statistically significant (P=0.035). Abnormal karyotypes were found in 50.6% of patients with EMI and 49.7% of patients without EMI. Only 11q23 abnormalities were associated with specific sites of EMI; lymphadenopathy (P=0.0111) and gingival hypertrophy (P=0.0016). Our study of adult AML patients demonstrates that EMI at diagnosis is associated with CD56 expression by leukemic blasts, 11q23 karyotypic abnormalities, low complete remission rate and poor overall survival.  相似文献

The clinical features and response to therapy of 32 Chinese patients with localised plasmacytoma are presented, and a comparison between extramedullary plasmacytoma (EMP) and solitary plasmacytoma of bone (SPB) is made. Twenty-two patients had SPB and ten had EMP, accounting for 9% of all of our plasma cell neoplasms. Both groups had a male predominance with a median age of 54 years for SPB and 63 years for EMP. The common sites of SPB included vertebral bodies (15) and the skull (4). Most EMPs occurred in the oronasopharynx (6) and paranasal sinuses (2). An M-protein was detected in eight patients with SPB and in six with EMP. Seventeen patients with SPB and seven with EMP received radiation therapy, and all achieved initial local control. The pattern of failure in 22 patients with SPB manifested as local recurrence in two, multiple bone metastases without bone marrow plasmacytosis in two, multiple EMP progression in two, and development of multiple myeloma (MM) in one. There were two local recurrences, one further solitary bone involvement and one MM conversion in the EMP group. Local recurrence or dissemination was associated with the appearance of M-protein or an increase in the M-protein level in both groups. There was no significant difference in M-protein status or incidence and patterns of failure between the two groups. Patients with EMP had a more favourable overall survival than those with SPB (P = 0.03). The 5 year disease-free survival rate was 79% for EMP and 58% for SPB (P = 0.53). Patients aged less than 60 years had a better overall survival in the SPB group, but location of tumour, presence of M-protein, radiation dose and chemotherapy did not influence prognosis in either group. Our results indicate that adequate local therapy can result in long-term survival with a low frequency of MM progression for patients with localised plasmacytomas, and both EMP and SPB appear to be similar in terms of frequency and patterns of failure.  相似文献

Currently, CD133 is one of the best markers to characterize cancer stem cells and Her-1 is reported as an important marker for the prognosis of triple-negative breast cancer. To investigate the relationship between the expression of CD133 and Her-1 and clinicopathology as well as prognosis in triple-negative breast cancer, 67 cases of triple-negative invasive ductal breast carcinoma taken from 422 patients with breast cancer were analyzed by immunohistochemistry and clinicopathology with follow-up. The CD133 and Her-1 were expressed as positive in 43.3% (29/67) and 53.7% (36/67) of patients, respectively. The expression of CD133 corresponded to tumor size (P = 0.022), clinical stage (P = 0.001) and lymphatic metastasis (P = 0.001), but not to age and histological grade. By Kaplan-Meier analysis the expression of CD133 was correlative with overall survival (OS) (log rank = 9.346, P = 0.002) and disease free survival (DFS) (log rank = 38.840, P = 0.0001) time of breast cancer patients. The expression of Her-1 was corresponding to tumor size (P = 0.031), clinical stage (P = 0.005) and lymphatic metastasis (P = 0.002), but not to age and histological grade. By Kaplan-Meier analysis the expression of Her-1 was correlative with overall survival (OS) (log rank = 7.998, P = 0.005) and DFS (log rank = 4.227, P = 0.040) time of patients with cancer. It is concluded that the expression of CD133 and Her-1 may be correlative with prognosis in triple-negative breast cancer.  相似文献
