Fourteen patients with poor-prognosis intermediate- to high-grade
non-Hodgkin's lymphoma
(
NHL
) associated with human immunodeficiency virus (HIV) infection (12 patients) or human T-cell leukemia virus type I (HTLV-I) infection (two patients) received cyclophosphamide 750 mg/m2, doxorubicin 50 mg/m2, and etoposide 240 mg/m2 administered as a continuous intravenous (IV) infusion over 4 days (infusional CDE); treatment was repeated every 28 or more days for up to six cycles. All HIV-positive patients had at least one poor prognostic feature, which included either extranodal disease (10 patients), Karnofsky performance status less than 70% (six patients), a CD4 count less than 100/microL (six patients), or a prior history of acquired immunodeficiency syndrome (AIDS; one patient). Both HTLV-I-positive patients had an elevated serum
lactate dehydrogenase
(
LDH
) level, a poor prognostic feature in that setting. Complete response (CR) occurred in 10 patients (71%; 95% confidence interval, 48% to 95%) and partial response (PR) occurred in three patients (21%), yielding an overall objective response rate of approximately 93%. The estimated Kaplan-Meier median survival was 17.4 months; seven of 12 HIV-positive patients are alive and disease-free with a median follow-up of 15 months (range, 7 to 24 months). Hospitalization was required after 19% of treatment cycles due to fever associated with granulocytopenia. Documented or suspected opportunistic infection occurred in five patients (36%), bacteremia occurred in three patients (21%), and candidemia occurred in one patient (7%). There was one treatment-related death attributable to disseminated aspergillosis. This pilot study suggests that infusional CDE may be a highly active regimen capable of producing durable remissions in a high proportion of patients with HIV-related
NHL
. Further study is required to confirm this observation.

Serum neural cell adhesion molecule (NCAM) has been described as a prognostic marker in multiple myeloma (MM). Both C-reactive protein (CRP) and beta 2-microglobulin (beta 2M) are established prognostic markers in MM. We tested the diagnostic value of these markers in 212 serum samples of patients with paraproteinemia registered prospectively in a population-based registry. Sixty patients had MM and 152 had other monoclonal gammopathies (hematologic diseases [48], paraneoplastic disease [35], autoimmune disease [15], and monoclonal gammopathy of undetermined significance [56]). CRP and beta 2M had wide and overlapping ranges in all diagnostic categories. However, serum neural cell adhesion molecule (NCAM) was low (< 20 U/mL) in all but 4 of 152 nonmyeloma cases and high (> or = 20 U/mL) in 31 (52%) of the 60 MM cases. Two patients with
non-Hodgkin's lymphoma
, 1 with chronic lymphatic leukemia, and 1 with autoimmune disease had serum NCAM values between 20 and 30 U/mL. In a discriminant analysis in which serum NCAM, CRP, beta 2M, paraprotein type and concentration, hemoglobin, leukocyte and thrombocyte counts, creatinine, corrected calcium,
lactate dehydrogenase
, and alkaline phosphatase were included, paraprotein type and concentration and serum NCAM turned out to be the best combination of parameters predicting whether a patient had MM, with 89% of cases being correctly classified. Even without bone marrow and x-ray examinations, serum NCAM, in combination with paraprotein type and concentration, can differentiate between MM and nonmyeloma patients.

A series of 520 cases of
non-Hodgkin's lymphoma
(NHL; 374 of B-cell, 130 of T-cell, 5 of non-B/non-T-cell, and 11 of undetermined phenotype) was analyzed for the presence of Epstein-Barr virus (EBV) using RNA in situ hybridization (RISH). The aims of the study were to assess the frequency of EBV-encoded small nuclear RNAs 1 and 2 (EBER), abundant immediate early RNAs (BHLF), and latent membrane protein-1 (LMP-1) in cases covering the entire histologic spectrum of NHL, and to analyze whether EBV status had prognostic relevance with regard to patient survival. EBER positivity was found in 25 of 374 (7%) B-NHL and 40 of 130 (31%) T-NHL (P < .00005) cases, but in only 1 of 16 cases with non-B/non-T-cell or undetermined phenotype. Among T-NHL cases, EBER positivity was confined to angioimmunoblastic, lymphadenopathy-like lymphoma (11 of 13 cases, 85%), Lennert's lymphoma (five of seven cases, 71%), and pleomorphic T-NHL (24 of 67 cases, 36%). Mycosis fungoides, lymphoblastic, and CD30-positive anaplastic large T-cell NHL cases were consistently EBV-negative. Double-labeling by RISH and immunophenotyping demonstrated the presence of EBV in neoplastic T cells, but no CD21 expression was found in the EBER-positive T-NHL cases. LMP-1 was expressed in 12 of 40 (30%) EBER-positive T-NHL and 5 of 25 (20%) EBER-positive B-NHL cases. For both T- and B-NHL, no correlation was found for EBER positivity and age, sex, clinical stage, or serum level of
lactate dehydrogenase
(
LDH
) at diagnosis. However, in T-NHL but not B-NHL, EBER positivity correlated with the presence of constitutional symptoms and a poor performance score (PS < 1; scale, 0 to 4). EBER status did not have any prognostic significance in B-NHL, but it had a negative prognostic impact in high-grade T-NHL (7-year survival of EBER-negative v EBER-positive cases: 33% v 14%; P = .01). A multivariate analysis including all B- and T-NHL of intermediate-/high-grade histology showed that EBER positivity in T-NHL was one of the three most significant factors recognized by the final prognostic model, only surpassed by PS greater than 1 and age greater than 67 years, and more powerful than B symptoms, an elevated
LDH
, or disseminated disease (clinical stage greater than II). We conclude that patients with EBV-positive T-NHL have a very poor clinical outcome, that EBV status should be considered as additional useful information in the classification of T-NHL, and that EBV-positive T-NHL should be treated as a separate entity in the future.

We report the first known case of fulminant bone marrow necrosis (BMN) occurring after infusion of fludarabine monophosphate in a patient with recurrent low-grade
non-Hodgkin's lymphoma
(
NHL
). Extensive BMN is characterized by the development of fever, bony pain, a leukoerythroblastic peripheral blood film, variable degrees of pancytopenia and elevations in
lactate dehydrogenase
and alkaline phosphatase. The diagnosis of BMN is rarely entertained ante-mortem. Although the precise role chemotherapy may have played in triggering fatal BMN remains speculative, we alert clinicians to be aware of this entity as more patients with indolent lymphomas and leukemias are treated with this and other potent nucleoside analogs.

We measured soluble interleukin-2 receptor (sIL-2R) levels in the cerebrospinal fluid (CSF) of patients with hematological malignancies especially, adult T-cell leukemia (ATL) and
non-Hodgkin's lymphoma
(
NHL
) with or without meningeal infiltration. CSF levels of sIL-2R were significantly higher in patients with ATL and
NHL
with meningeal infiltration than in patients with both diseases without meningeal infiltration. The sIL-2R levels in CSF were elevated in 4/4 ATL patients (100%) and 3/13
NHL
patients (23%) with meningeal infiltration. CSF levels of sIL-2R from ATL patients with meningeal infiltration had a tendency to elevate in correlation with numbers of mononuclear cells and
lactic dehydrogenase
(
LDH
) in CSF. However, these had no correlation with serum levels of sIL-2R. Therefore, sIL-2 levels in CSF may be useful in the diagnosis of meningeal infiltration in patients with ATL, are probably specific markers for meningeal infiltration of ATL.

Extranodal
non-Hodgkin's lymphoma
in the head and neck, especially T-cell lymphoma of the lethal midline granuloma (LMG) type, has unique clinical and histologic features differentiating it from other lymphomas. The authors measured soluble intercellular adhesion molecule-1 (ICAM-1) in sera from 12 patients with T-cell lymphoma of the LMG type and from 52 patients with other head and neck non-Hodgkin's lymphomas, by double-determinant immunoassay. The expression of ICAM-1 in lymphoma tissue was examined in 26 patients by the avidin-biotin immunoperoxidase method. The serum ICAM-1 levels were significantly higher in T-cell lymphoma of the LMG type than in other head and neck lymphomas or in healthy adult controls. Elevated levels of serum ICAM-1 were associated with increased levels of serum
lactate dehydrogenase
, poor prognosis, and impaired T-cell-dependent immune functions, both in T-cell lymphoma of the LMG type and in other head and neck lymphomas. When we monitored serum ICAM-1 levels in individual patients, the level decreased in the complete remission interval compared to before treatment and went up again when the lymphoma relapsed. Although the staining intensities of ICAM-1 in lymphoma cells were not related to serum ICAM-1 levels, a markedly intense expression of ICAM-1 was found on the angiocentric or angiodestructive lymphoreticular infiltrate region in the tissues from T-cell lymphoma of the LMG type. A higher serum ICAM-1 level and its tissue expression in T-cell lymphoma of the LMG type may be one of the clues to understanding this particular lymphoma. The serum ICAM-1 level could be an efficient parameter for monitoring the clinical course of head and neck non-Hodgkin's lymphomas.

A case of primary lymphoma of the liver in a patient with acquired immunodeficiency syndrome (AIDS) is presented. Persistent fever, tender hepatomegaly, and mildly abnormal liver function tests combined with an elevated
lactate dehydrogenase
level gave the clue for the diagnosis. High-grade,
non-Hodgkin's lymphoma
of B-cell phenotype was demonstrated by percutaneous liver biopsy. Primary hepatic lymphoma is a rare event among patients with AIDS. We reviewed the cases in the literature and noted that a preponderance of these patients presented with multiple lesions (a rather rare occurrence in primary lymphoma of the liver in patients not infected with the human immunodeficiency virus).

Between August 1985 and January 1994, 73 evaluable adult patients with bulky localized or advanced-stage, intermediate- and high-grade de novo
non-Hodgkin's lymphoma
(
NHL
) were treated with MECOP-B (methotrexate and leucovorin rescue, epirubicin, cyclophosphamide, vincristine, prednisone, and bleomycin). Over a median follow-up of 32 months (range, 4-98 months), 55 patients (75%) achieved complete remission (CR) (95% confidence interval, 81-69%) and 3 attained partial remission (PR) (4%) for an overall response rate of 79%. Using a multiple regression analysis where the dependent variable was response to therapy (CR vs. PR + treatment failure), poor performance status, and the presence of a bulky disease were negatively associated with the likelihood of achieving CR. Survival analysis showed that 49 (67%) patients (95% confidence interval, 74 and 60%) were alive, of whom 47 (64%) were disease-free. While the median survival has not been reached, the actuarial survival probability at 5 years +/- SE was 64 +/- 6%. Time to treatment failure for those attaining CR was also estimated. While the median survival has not been reached, probability of freedom from treatment failure at 5 years +/- SE was estimated as 74 +/- 7%. However, the long-term CR (CR rate times disease-free survival rate) was only 48%, and the 'measurement of efficacy' was 53%. These results were inferior to those from our earlier reports. The proportional hazards model of Cox identified poor performance status, older age, and high
lactate dehydrogenase
as factors with an adverse effect on survival. Using the results of the model, patients were categorized into three predefined risk groups with significant differences in outcome. Toxicity of the regimen was high, but comparable to that reported in the literature with a toxic death rate of 8%. We conclude that MECOP-B is an effective therapy for patients with aggressive
NHL
; however, based on the current results as compared with our earlier analysis, besides the emergence of prognostic factors, therapy of
NHL
should be individualized. Less expensive, less toxic regimens should be used for lower-risk patients, while the use of more intense, more toxic, more expensive programs should only be offered to those with a predicted poor outcome.

We describe two cases of
non-Hodgkin's lymphoma
associated with t(3;6)(q27;p21.3) and BCL6 rearrangement. The first case was in a 78-year old woman, whose performance status (PS) was 1, the serum
lactate dehydrogenase
(
LDH
) level was elevated, and the Ann Arbor stage was IIIA with no extra nodal lymphomatous site. The pathological diagnosis from a biopsy of the inguinal lymph node was 'malignant lymphoma (ML), follicular, small cleaved' according to the Working Formulation. Complete remission was achieved. Although she had relapse in 1992, remission was obtained again. The second case was in a 62-year old man, whose PS was 1, the serum
LDH
was normal, and Ann Arbor stage was IVA with the involvement of the small intestine. Histological diagnosis of the cervical lymph node was 'ML, diffuse, large cell'. Complete remission was obtained without relapse. The 3q27 translocations, found in 20-30% of
non-Hodgkin's lymphoma
, are unique in having multiple chromosomal translocation partners. Chromosome band 6p21.3 is one of these partner sites that may be the site of a novel gene. The two cases presented here show that this translocation is a non-random chromosomal change involving 3q27 and BCL6. Since t(3;6) was the sole karyotypic abnormality in one case, this translocation may play a role in lymphomagenesis.

We describe a case of peripheral T cell lymphoma that is remarkable for its fulminate course and selective targeting of both kidneys. The patient was a 6-year-old girl who was in her usual state of good health until the onset of abdominal pain and fever. She was treated for acute oliguric renal failure and visual disturbances. A renal biopsy was performed. Biopsy findings were interpreted as suggestive of a vasculitic process, and treatment was initiated for a presumptive diagnosis of Wegener's granulomatosis. The patient died 3 days following admission, and autopsy revealed extensive bilateral kidney infiltration by a peripheral T cell lymphoma. The remainder of the body was spared with the exception of mild infiltration of the pulmonary parenchyma and choroid plexus by neoplastic lymphocytes. The neoplastic nature of the disease was confirmed utilizing immunoperoxidase stains and T cell receptor gene rearrangement. Primary renal lymphoma and renal failure attributable to involvement by lymphoma are rare findings that should be considered when other more common causes of renal insufficiency have been excluded. The presenting clinical complaints are generally of short duration, nonspecific, and atypical. Most patients exhibit oliguria. Physical examination may reveal hepatosplenomegaly, lymphadenopathy, and flank and/or abdominal mass(es). Laboratory findings frequently include an elevated serum creatinine, blood urea nitrogen,
lactate dehydrogenase
, and a mild proteinuria. Electrolyte abnormalities are variably present. Possible radiographic findings include hypodense or hypoechoic renal lesions and diffuse bilateral renal enlargement. Although the prognosis is dismal, survival may be prolonged utilizing current treatment modalities, and rare patients may be "cured" of disease. The clinical presentation, radiological findings, and prognosis of patients with clinically evident renal involvement by
non-Hodgkin's lymphoma
are discussed.
