The incidence of systemic non-Hodgkin lymphoma (NHL) has only slightly
decreased since the introduction of highly active antiretroviral therapy
(HAART), suggesting that current antiretroviral strategies do not
eliminate the lymphoma risk. This study evaluates the evolving
characteristics of HIV and NHL between the pre-HAART and the post-HAART
periods in 246 HIV-infected NHL patients from a single institution.
Major HIV-related characteristics were similar in the two periods. Most
patients in the post-HAART period presented with unknown (23%),
untreated (16%), or uncontrolled (37%) HIV infection. Despite an
increased frequency of advanced stage IV disease in the post-HAART
period (68% vs. 53%, p =.03), the overall survival has improved, with a
2-year survival probability of 61.6% versus 35.9%, (p <.001). This was
associated with an increased complete remission rate (69% vs. 55%, p
=.04) and the generalization of more intensive chemotherapy regimens.
Most patients (76%) who developed NHL in the post-HAART period had
uncontrolled HIV replication. However, 27 patients (24%) developed NHL
despite an effective viral suppression at NHL diagnosis. Patients who
were naive to any antiretroviral therapy at NHL diagnosis had an overall
survival probability very similar to that of patients with controlled
HIV replication.Improvement in the overall survival rate in the
post-HAART period was associated with more intensive chemotherapy
regimens, increased complete remission rate, and a likely benefit of
continuation or introduction of HAART.

Absolute level of Epstein-Barr virus DNA in human immunodeficiency virus
type 1 infection is not predictive of AIDS-related non-Hodgkin lymphoma.

To study whether Epstein-Barr virus (EBV) load can be used to predict
the occurrence of acquired immunodeficiency syndrome-related non-Hodgkin
lymphoma (AIDS-NHL), we determined EBV load longitudinally for
individuals infected with human immunodeficiency virus type 1. EBV load
in peripheral blood mononuclear cells (PBMC) was high and displayed
considerable fluctuations over time, indicating that absolute EBV load
in PBMC is not predictive of the development of AIDS-NHL. EBV DNA was
also detectable in serum at some time points but at a lower level.

A 36-year-old HIV-seropositive man developed progressive confusion and
unilateral tremor of the hand. His medical history included cryptococcal
meningitis and CMV colitis. CT scan revealed a single hyperdense mass
with minimal peripheral enhancement at the region of the cerebral
peduncle and pons, causing obstructive hydrocephalus. He was treated
with ventriculo-peritoneal shunt and cranial radiotherapy. He also
received treatment with highly active antiretroviral therapy (HAART). A
CD4+ cell count was increased from 2 to 345 cells/mm3. He returned to
normal function for about 32 months after treatment.

Expression of RB2/p130 tumor-suppressor gene in AIDS-related
non-Hodgkin's lymphomas: implications for disease pathogenesis.
SO - Hum Pathol 2002 Jul;33(7):723-31
AD - Institute of Pathological Anatomy and Histology, University of Siena,
Siena, Italy.
In this study we examined 21 cases of AIDS-related lymphomas for genomic
organization and expression of RB2/p130 oncosuppressor gene and compared
the results with the proliferative features of these neoplasms. We found
no mutations in the RB2/p130 gene and unusually high percentages of
cells expressing nuclear pRb2/p130 in tumors with a high proliferative
activity, such as AIDS-related lymphomas. These findings might suggest
that a molecular mechanism usually observed in viral-linked oncogenesis
could be involved. We performed in vitro and in vivo binding assays to
investigate whether the human immunodeficiency virus (HIV) gene product
Tat and Rb2/p130 could interact. The results of these assays revealed
that the HIV-1 Tat protein binds specifically to pRb2/p130. This may
result in the inactivation of its oncosuppressive properties and the
induction of genes needed to proceed through the cell cycle including
p107, cyclin A, and cyclin B. Using single-cell polymerase chain
reaction (PCR) assay, we found HIV-1 DNA in the neoplastic cells of only
2 of the 21 cases examined, whereas PCR on whole tissue revealed HIV-1
DNA in all of the cases. Furthermore, a diffuse and nuclear stain was
observed in tissue sections with anti-Tat monoclonal antibody. These
findings are in accordance with the notion that soluble Tat protein
could function as a biologically active extracellular protein released
by infected cells and taken up readily by uninfected B cells. In
conclusion, our results seem to suggest that pRb2/p130 oncosuppressor
protein may be a target in the interaction between the HIV-1 gene
products and host proteins. Copyright 2002, Elsevier Science (USA). All

Expression profile of MUM1/IRF4, BCL-6, and CD138/syndecan-1 defines
novel histogenetic subsets of human immunodeficiency virus-related
lymphomas.
SO - Blood 2001 Feb 1;97(3):744-51

Oncologico, Istituto Nazionale Tumori, IRCCS, Aviano, Italy.
This study was aimed at defining the histogenesis of the pathologic
spectrum of lymphoma arising in the context of human immunodeficiency
virus (HIV) infection. Toward this aim, 87 AIDS-related non-Hodgkin
lymphomas (AIDS-NHL) and 16 Hodgkin lymphomas arising in HIV+ patients
(HIV-HL) were comparatively analyzed for the expression pattern of
several B-cell histogenetic markers, including BCL-6 (expressed by
centroblasts and centrocytes), MUM1/IRF4 (expressed by late centrocytes
and post-germinal center [GC] B cells), and CD138/syn-1 (expressed by
post-GC B cells). Expression of MUM1, BCL-6, and syn-1 segregated 3
major phenotypic patterns among AIDS-NHL and HIV-HL: (1) the
BCL-6+/MUM1-/syn-1- pattern, selectively clustering with a large
fraction of AIDS-Burkitt lymphoma (17 of 19) and of systemic
AIDS-diffuse large cell lymphoma (12 of 16); (2) the BCL-6-/MUM1+/syn-1-
pattern, associated with a fraction of AIDS-immunoblastic lymphoma (8 of
24); and (3) the BCL-6-/MUM1+/syn-1+ pattern, associated with systemic
and primary central nervous system immunoblastic lymphoma (14 of 24) and
with primary effusion lymphoma (10 of 10), plasmablastic lymphoma of the
oral cavity (7 of 7), and HIV-HL (15 of 16). Analysis of nonneoplastic
lymph nodes showed that the 3 phenotypic patterns detected in AIDS-NHL
and HIV-HL correspond to distinct stages of physiologic B-cell
development-centroblasts (BCL-6+/MUM1-/syn-1-), late GC/early post-GC B
cells (BCL-6-/MUM1+/syn-1-), and post-GC B cells (BCL-6-/MUM1+/syn-1+).
Expression of the Epstein-Barr virus-encoded latent membrane protein-1
clustered with the BCL-6-/MUM1+/syn-1+ profile throughout the
clinicopathologic spectrum of AIDS-NHL and HIV-HL. Overall, these
results define novel histogenetic subsets of AIDS-NHL and HIV-HL and may
provide novel tools for refining the diagnosis of these disorders.

Expression of cyclin-dependent kinase inhibitor p27(Kip1) in
AIDS-related diffuse large-cell lymphomas is associated with
Epstein-Barr virus-encoded latent membrane protein 1.

Knowledge of the role of cell-cycle regulators in the pathogenesis of
acquired immune deficiency syndrome-related non-Hodgkin's lymphomas
(AIDS-NHLs) is scarce. Here we analyzed 86 systemic AIDS-NHLs and 20
AIDS-primary central nervous system lymphomas for expression of
p27(Kip1), a negative regulator of cell-cycle progression belonging to
the Kip family of cyclin-dependent kinase inhibitors. In parallel, we
investigated the relationship between p27(Kip1), the lymphoma
proliferation index, Epstein-Barr virus status, expression of cellular
cyclin D3 and cyclin D1, and B-cell differentiation stage. We report
that AIDS-immunoblastic lymphomas (AIDS-IBLs), either systemic or
primarily localized to the central nervous system, consistently express
p27(Kip1) protein (19 of 24 and 10 of 14, respectively) despite the high
proliferative rate of the lymphoma clone, suggesting a failure of
p27(Kip1) to inhibit the cell cycle in AIDS-IBL. Conversely, the
remaining systemic AIDS-NHLs and AIDS-primary central nervous system
lymphomas preferentially fail to express p27(Kip1). Expression of
p27(Kip1) in Epstein-Barr virus-positive AIDS-NHLs generally associates
with latent membrane protein 1 (LMP1) expression and is related to a
late stage of B-cell differentiation, characterized by the
BCL-6-/MUM1+/syn-1+/- phenotypic profile, whereas it seems to be
unrelated to the expression of cellular cyclins. In B cells in vitro,
induction of LMP-1 expression under the control of inducible promoters
up-regulates expression of p27(Kip1), thus providing a putative
mechanistic explanation for the association between LMP1 and p27(Kip1)
observed in vivo. Overall, these data show that AIDS-IBL pathogenesis is
characterized by loss of the inverse relationship between p27(Kip1)
positivity and tumor growth fraction that is otherwise generally
observed in normal lymphoid tissues and in most other types of NHLs.

Human herpesvirus-8-associated lymphoma of the bowel in human
immunodeficiency virus-positive patients without history of primary
effusion lymphoma.
SO - Hum Pathol 2002 Aug;33(8):846-9
AD - Laboratoire d'Anatomie Pathologique, Centre Hospitalier Universitaire de
Purpan, Toulouse, France.
This report describes two cases of human herpesvirus-8
(HHV-8)-associated large cell lymphoma of the bowel in human
immunodeficiency virus (HIV)-positive men. Immunohistochemistry provides
evidence of HHV-8 infection of the lymphoma cells (LNA1+, vIL-6+). In
both cases, lymphoma cells were coinfected by the Epstein-Barr virus.
One case was of B-cell lineage, but the second one was of null phenotype
with isolated expression of the CD3 molecule. However, in the latter
case, assessment of B- or T-cell clonality remained elusive. The chief
finding for these two cases was the lack of history of primary effusion
lymphoma. There was an apparent restriction of the tumor to the large
bowel in the first case. For the second case, the bowel tumor was
preceded by lymph node and liver involvement. The cases suggest that the
incidence of HHV-8 infection in large cell lymphoma arising in the
setting of HIV infection (other than primary effusion lymphoma) may be
underestimated and that the detection of the viral gene products would
be appropriate for greater understanding of the pathogenesis of these
tumors. HUM PATHOL 33:846-849. Copyright 2002, Elsevier Science (USA).

BACKGROUND AND OBJECTIVES: Intensive chemotherapy (CHT) in AIDS-related
non-Hodgkin's lymphoma (AIDS-NHL patients) is a vexing problem. Our
purpose was to evaluate the feasibility of a high dose idarubicin
(HD-IDA)-based regimen in diffuse large cell (DLC) AIDS-NHL patients.
DESIGN AND METHODS: Fourteen stage I-IV untreated DLC AIDS-NHL patients
with a performance status <3 and no prior AIDS-related diseases received
CIOD: cyclophosphamide, HD-IDA (25 mg/m2 in 8 patients, 20 mg/m2 in 6
patients) vincristine and dexamethasone plus granulocyte
colony-stimulating factor (G-CSF) and prophylaxis against infections.
The outcomes measured were: rate of response, disease-free survival
(DFS), overall survival (OS) and the impact of chemotherapy on
immunologic and virological parameters. RESULTS: Complete response was
achieved in 13/14 cases (response rate: 93%). The median time of
response and survival was 33 (range 5-79) and 35.5 (range 6-84) months,
respectively. At 60 months the DFS and OS were 71% and 44%,
respectively. CIOD with idarubicin 20 mg/m2 was better tolerated than
that with 25 mg/m2 and was administered with a higher mean
average-relative-dose-intensity (95.38+/-7% vs 83.35+/-15.59%,
p=0.0001). Opportunistic infections were more frequent in patients with
a baseline CD4 <100 than those with >100 cells/microL (4/5 vs 1/9:
p=0.0229). After 3 CIOD courses the mean CD4 cells/microL was
significantly lower (p=0.001) and the mean HIV.1 RNA load was
significantly higher (p=0.045) than at baseline. INTERPRETATION AND
CONCLUSIONS: The proposed chemotherapeutic regimen for AIDS-related
non-Hodgkin's lymphoma is feasible in an outpatient setting in selected
patients with relatively well-preserved immune function.
