A panel of commercially available monoclonal antibodies (MoAbs) including LN1, LN2, MB2, L26, Leu M1, UCHL1, MT1 and L60 was used to evaluate a diverse group of neoplastic processes in 256 Zenker's-fixed, decalcified, paraffin-embedded bone marrow biopsies using the ABC immunoperoxidase technique. LN2 and MB2 were useful in delineating the extent of B-cell lymphoproliferative processes and in identifying interstitial patterns of involvement. The combined application of LN2, MB2 and UCHL1 had utility in differentiating B-cell from T-cell lymphoproliferative processes; in no instance was reactivity with LN2 observed in T-cell processes. The combined application of these three MoAbs was also used in differentiating benign reactive lymphoid aggregates from focal malignant B-cell proliferations. LN2 exhibited positivity with the Reed-Sternberg cells (RSC) of Hodgkin's Disease (HD) and significantly aided in the identification of these cells. Staining of RSC with Leu M1 was inconsistent and was observed in only 50% of cases of HD. Use of the entire panel of MoAbs together with more recently available reagents such as Cathepsin G, MAC 387 and neutrophil elastase was essential in optimally evaluating a particular lesion; none of these MoAbs used singly reliably differentiated myeloid from lymphoid, hematopoietic from metastatic, or reactive from malignant processes.

Lymphoid cells in human bone marrow are either assembled focally or occur in a diffuse, loosely scattered infiltrate. While the focal lesions are easily detected, the lymphoid cells of the diffuse infiltrate are hardly recognizable with conventional stains. Quantitative immunohistological analysis of 103 trephine biopsies, including cases with reactive disorders (e.g. myeloid hyperplasia, aplastic anaemia) and neoplastic processes (e.g. myeloproliferative disorders, B-cell non-Hodgkin's lymphomas) and some specimens with normal architecture yielded the following results: (1) Various antibodies recognizing B cells (L26, 4KB5, MB1, Ki-B3), T cells (UCHL1, MT1) and NK cells (Leu-7) are effective in paraffin-embedded bone marrow sections, thus enabling analysis of the in situ distribution of normal lymphocyte subsets and subtyping of lymphomatous infiltrates. (2) The lymphocytes of the diffuse infiltrate constituted about 1-5% of all nucleated cells in normal bone marrow. (3) In the diffuse infiltrate, T lymphocytes were regularly observed in higher numbers than B cells, and Leu-7+ cells were rare or virtually absent, irrespective of the diagnosis. (4) The focally assembled lymphoid cells were mainly B lymphocytes, but many T cells were always intermingled. This was true for both reactive follicles and neoplastic lymphomatous infiltrates, which generally cannot be differentiated on the basis of immunohistological findings alone.

The diagnostic value of immunohistochemistry using monoclonal antibodies was assessed in 100 liver biopsy specimens. The majority of these cases were hepatic localizations of lymphoid malignancies. Ten normal and reactive inflammatory liver biopsies were used as controls. Some monoclonal antibodies directed against leukocyte antigens revealed unexpected reactivities with normal liver structures: biliary tract (anti-CD10, anti-B MB2) and hepatocytes (anti-B LN1). In 12/17 cases of hepatic involvement by large cell malignancy, immunohistochemistry allowed the diagnosis of non Hodgkin's lymphoma (NHL); the remaining 5 cases were metastatic undifferentiated carcinoma. It was difficult to differentiate small cell liver NHL from reactive inflammatory infiltration. New anti-B (MB1, MB2, 4KB5, LN1 and LN2) and anti-T (MT1 and UCHL1) monoclonal antibodies suitable for use on paraffin sections were of value to phenotype NHL when only fixed material was available. But, information was too limited to distinguish malignant from reactive infiltrates. Immunohistochemistry on frozen sections was often necessary to diagnose inflammatory infiltrates and to phenotype NHL. Most NHL were of B cell origin (11/13 cases) and showed monotypic surface immunoglobulins as well as B cell-associated antigens (CD22+). The expression of the T CD5 antigen by B-cell NHL may have some diagnostic value. When monotypic surface immunoglobulins could not be demonstrated (due to background staining) the expression of this antigen by B lymphocytes was considered to be highly indicative of their neoplastic nature. Hairy cell leukemia exhibited a pathognomonic phenotype on frozen sections (CD11c+, CD22+, CD25+). T NHL were rare (2 cases) and difficult to diagnose due to the lack of clonal markers. The diagnosis of Hodgkin's disease in liver (15/20 cases) was facilitated by using paraffin sections of both monoclonal antibodies anti-CD15 (Leu M1) and anti-CD30 (Ber-H2) which detect fixation-resistant antigens expressed by Sternberg cells.

A panel of paraffin effective antibodies recognizing B cells and T cells (LN-2, MB1, L26, MT1, UCHL1, kappa, lambda) was used to characterize the immunophenotypes of 26 sinonasal non-Hodgkin's lymphomas. Seventeen tumors were stage I, five were stage II, one was stage III, and three were stage IV. Nine lymphomas were classified morphologically as large cell, six were large cell immunoblastic, six were small cleaved cell, two were mixed small and large cell, two were small noncleaved cell, and one was lymphoblastic. None were follicular. Twenty-two lymphomas had a B cell immunophenotype, three were T cell neoplasms, and one was immunoreactive only for MT1. This predominance of sinonasal lymphomas with a B cell immunophenotype in patients residing in the United States contrasts with the almost exclusive occurrence of T cell sinonasal lymphomas in Chinese patients living in Hong Kong and Japanese patients residing in regions of Japan that are nonendemic for human T cell leukemia virus-1.

Diffuse, mixed small and large cell lymphomas (DML) are a heterogeneous group of non-Hodgkin's lymphomas. There are only a few published immunophenotypic and/or genotypic studies of DML, and they include a small number of cases. It is unclear whether these neoplasms are monoclonal, oligoclonal, or perhaps of dual lineage. Using monoclonal antibodies (UCHL1, MB2, MT1, LN1, LN2, and L26) that are effective in paraffin-embedded, B5-fixed tissue, 13 cases of DML were studied. This method allowed for improved correlation between cell morphology and immunophenotype compared with frozen section immunohistology. In addition, Southern blotting/DNA hybridization was used to identify directly the lineage of the neoplastic cell population. In each case a population of large B lymphocytes was demonstrated by immunohistology. In six of the cases, a single class of immunoglobulin light chains was detected by frozen section immunohistology, cytospin immunocytology, or both supporting the hypothesis that the B lymphocytes are monoclonal. In almost all the cases (12 of 13), the small cell population consisted predominantly of T lymphocytes. Immunoglobulin gene rearrangements were detected in seven cases, but no T cell receptor gene rearrangements were detected. It was concluded that DML are monoclonal lymphomas of B cell lineage with a non-neoplastic T cell component.

A novel, comprehensive panel of monoclonal antibodies was tested in a large series of routinely processed lymph node biopsy specimens from patients with Hodgkin's disease (69 cases), with the object of developing either definitive or adjunctive diagnostic criteria. B- and T-cell lymphomas and reactive states that could mimic Hodgkin's disease were also assessed with the same monoclonal antibody panel. In addition to the popularly used anti-Leu-M1 (CD15), the panel included the recently produced Ber-H2 (CD30) antibody, which detects a formalin-resistant epitope of the Ki-1 antigen. The other monoclonal antibodies were directed against epithelial membrane antigen (Dako-EMA) and leukocyte common antigen (Dako-LC) (CD45), as well as B-cell (LN-1 and LN-2) and T-cell (MT1) associated antigens. The results showed clear phenotypic separation of nodular lymphocyte predominant subtype of Hodgkin's disease from other subtypes. The lymphocytic and histiocytic cells of nodular lymphocyte predominant Hodgkin's disease were reactive for LN-1 (all cases) and anti-EMA (most cases) but negative for anti-Leu-M1 and Ber-H2. Within the other subtypes--i.e. nodular sclerosis and mixed cellularity--nearly all Reed-Sternberg cells and Hodgkin's cells were positive for both anti-Leu-M1 and Ber-H2. Ber-H2 monoclonal antibody was observed to react more frequently with Reed-Sternberg cells and Hodgkin's cells in Bouin's- or formalin-fixed tissues. Pleomorphic T-cell lymphomas, which could mimic Hodgkin's disease on morphology, created the same problem on phenotypic analysis. However, MT1 identified a significant proportion of T-cell lymphomas with Reed-Sternberg-like cells, having proven negative for Reed-Sternberg cells and Hodgkin's cells in Hodgkin's disease. Thus, a combination of anti-Leu-M1, Ber-H2, anti-EMA, LN-1, and MT1 monoclonal antibodies appears at present to be the most useful panel for the diagnosis and the differential diagnosis of Hodgkin's disease.

The monoclonal antibodies F8-11-13, 4KB5, MB1, and MB2 recognize largely B-cell-restricted antigenic determinants that resist routine processing. Similarly, MT1, MT2, and UCHL1 react with fixation-resistant T-cell-restricted antigens. In order to evaluate the diagnostic potential of these antibodies, the authors have assessed their immunoreactivity with a series of 81 formalin-fixed and paraffin-embedded non-Hodgkin's lymphomas (48 B-cell, 33 T-cell) encompassing a wide variety of histologic subtypes, which had been fully characterized by frozen-section immunophenotyping. Ninety-six percent of B-cell lymphomas reacted with one or more of the B-cell-associated antibodies, whereas 100% of T-cell lymphomas reacted either with MT1, UCHL1, or both antibodies. MT2 was of no value in distinguishing between B- and T-cell lymphomas. None of the antibodies was entirely lineage specific; furthermore, a proportion of cases failed to react with one or more of the B- or T-cell-associated antibodies. Although these antibodies provide useful information in distinguishing between T- and B-cell lymphomas, the authors suggest that a panel of these antibodies is necessary for accurate determination of the histogenesis of these tumors. As with any immunohistochemical marker, interpretation of the immunostaining must be in the context of the morphologic features.

We studied 11 cases of malignant lymphoma diagnosed concurrently with or following lymph node infarction. Cases included seven B-cell lymphomas, three T-cell lymphomas, and one case of Hodgkin's disease. Sections of viable and infarcted tissue were immunostained in parallel using a panel of antibodies effective in routinely processed, wax-embedded tissue. The panel included anti-leucocyte-common antigen (CD45), T-cell-associated antigens (UCHL1, MT1), B-cell-associated antigens (MB1, 4KB5 (CD45R), MT2, LN1), a B-cell-specific antigen (L26), C3D-1 (CD15), and BER-H2 (CD30). Antibodies to intermediate filament cytoskeletal proteins, epithelial membrane antigen, and Factor VIII-related antigen were also used. In eight cases, staining of the infarcted material gave evidence of a lymphoid proliferation of either T- or B-cell type; an in the case of Hodgkin's disease, the results supported this diagnosis. The immunophenotype derived in the infarcted tissue mirrored the findings in the viable material in these eight cases of non-Hodgkin's lymphoma. A case of testicular infarction with concurrent intraosseous lymphoma was also examined. Staining in this case provided evidence of infarcted lymphoma. Thus, immunostaining of infarcted lymphoid tissue with these novel antibodies provides valuable information that conventional light microscopy cannot offer.

Reagents that recognize antigens on lymphoid cells in fixed and wax-embedded sections have been applied to a series of cases of non-Hodgkin's lymphomas. The panel consisted of MB1, 4KB5 (CD45r), LN1, L26 and MB2 which recognize antigens expressed predominantly on B-lymphocytes; UCHL1 and MT1 which recognize antigens expressed on T-lymphocytes and myeloid cells; antibodies recognizing the non-lineage antigens LeuM1 (CD15), BerH2 (CD30), anti-EMA; anti-lysozyme and MAC 387 which detect antigens present on some macrophages; and finally TAL1B5 (class II MHC), CAM 5.2 (low molecular weight cytokeratin) and PD7/26 + 2B11(CD45). Two hundred and four cases of non-Hodgkin's lymphoma have been studied, of which 158 had been fully characterized on frozen sections. The series was biased towards high-grade (n = 108) and T-cell (n = 44) tumours and these were largely prospectively accrued. It was found that discrimination between B-cell and T-cell lymphomas can be reliably achieved using these reagents and that a small panel (CD45, L26, MB2, MT1, UCHL1) is adequate for this purpose. Using the full range of reagents it is not possible to subdivide cases into groups that correspond with morphological subtypes of lymphoma. Although paraffin section immunohistochemistry is of value, the diagnosis of lymphoproliferative disorders must still be based upon the assessment of well fixed, carefully prepared tissue sections using conventional tinctorial methods.

Immunophenotyping of hematopoietic malignancies is usually accomplished in frozen sections or cell suspensions. To determine whether this procedure was also feasible in paraffin sections, we performed a double-blind immunoperoxidase study of 65 hematopoietic tumors whose phenotypes had been determined previously in fresh tissue. A selected antibody panel was used, including anti-LN2, UCHL-1, anti-cathepsin B, anti-Leu M1, anti-MB2, and anti-MT1. A correct phenotype was obtained on paraffin sections in 95% of cases. All 31 B-cell malignancies were properly classified, showing reactivity for LN2 and MB2. In 14 of 15 T-cell hematopoietic malignancies, all cells reacted with anti-MT1 and/or UCHL-1; the 1 case negative for these antigens was misdiagnosed as a B-cell tumor because of misinterpreted LN2 reactivity in benign histiocytes. Four of 5 true histiocytic neoplasms were positive for cathepsin B and LN2 but lacked other antigens; the fifth case was wrongly considered a B-cell proliferation because only bland histiocytes displayed cathepsin B. Only 1 of 7 Hodgkin's lymphomas was misdiagnosed (as a T-cell tumor); in the other 6 cases, Reed-Sternberg cells were reactive for LN2 and LEU M1. Five of 6 extramedullary myeloid leukemias also stained for LN2, MT1, and LEU M1. One showed LN2, MB2, and MT1; this case was classified as a B-cell neoplasm and indeed represented a pre-B-cell transformation of chronic myelogenous leukemia. These results show that the specified panel of antibodies may be useful for immunophenotyping of hematopoietic neoplasms when only paraffin sections are available for analysis. However, it cannot supplant traditional cell-marker studies of hematopoietic tumors because of its lesser accuracy.
