Cytogenetic studies were performed in 21 cases of
Hodgkin's disease
. Fourteen cases revealed chromosomally aberrant clones which could be fully described in 12 cases. Two cases showed different unrelated clones and five cases only single cell aberrations. Recurrent breakpoints were 1p13/21 (six cases), 7q32/34 (five cases), 2p16/21 and 19p13 (four cases each), 4q25/28, 6q15/21 and 12q22/23 (three cases each). In two cases, a translocation between band 19q13 and band 14q11 or 14q32 was found. This finding may indicate that an unknown oncogene in 19p13 is activated by juxtaposition next to a T-cell receptor or immunoglobulin gene in 14q11 or 14q32, respectively. In eight cases each, total or partial monosomy 4 or 6 was present suggesting that tumor suppressor genes in 4q or 6q play a role in tumor development in
Hodgkin's disease
. Moreover, the aberrant clones lacked the Y-chromosome in men and the second X-chromosome in women in eight out of nine and in two out of three cases, respectively. Although different cell populations, especially T cells, showed mitotic activity in unstimulated short term culture, combined immunophenotyping and karyotyping unequivocally demonstrated that CD30 and CD15 positive
Hodgkin
and Sternberg-Reed cells represented the chromosomally aberrant clones.

Hodgkin's disease
(HD) is perceived to be a malignant disease of the lymphoid system. One of the main obstacles into the investigation of the cell biology of
Hodgkin's disease
is the relative paucity of Reed-Sternberg cells (or variants), the presumed neoplastic component of this condition, which often make up less than 1% of the total cell number.

A new human T-cell non-
Hodgkin lymphoma
cell line of the T-cell receptor (TCR) gamma/delta lineage has been derived from the peripheral blood of a patient with a subcutaneous T-cell lymphoma in leukemic phase. The cell line (Karpas 384) initially had the same characteristics as malignant cells from the patient. Both the original tumor and the cell line failed to express any T-cell differentiation antigens other than very weak cell-surface expression of CD3 and cytoplasmic CD7; with continued growth in vitro, surface CD3 became undetectable in the presence of maintained strong cytoplasmic expression. The cell line has a complex karyotype with six abnormal chromosomes exhibiting not only t(7;14) (p13;q11.2) but also inv7(p13;q22.1), t(1;2)(q11;q35), t(2;1;14) (q35;q11-q32.1;q22.1), interstitial deletion 12(q24.1q24.3), and an unidentified marker chromosome. DNA blot analysis showed that TCR C beta and TCR J alpha-C alpha DNA sequences were in germline configuration in all restriction endonuclease digests. TCR gamma sequences showed biallelic V gamma 9-J gamma P-C gamma 1 rearrangements, the TCR gamma rearrangement detected in the majority of normal TCR gamma/delta bearing cells. Use of a range of TCR delta probes showed biallelic deletion of both J delta 1 and J delta 2, but three rearranged fragments when probed with a 3' C delta genomic probe. Similar breakpoints at 7p13 have been reported in a wide range of hematologic malignancies. Molecular cloning of the t(7;14)(p13;q11.2) translocation breakpoint in this cell line may define new DNA sequences of oncogenic potential at the 7p13 locus.

Serum levels of interleukin-2 receptor (IL2R) were determined in children with newly diagnosed
Hodgkin disease
(n = 68), Wilms tumor (n = 20), osteosarcoma (n = 18), rhabdomyosarcoma (n = 18), or Ewing sarcoma (n = 15). Measurements of soluble IL2R were positively correlated with disease stage in
Hodgkin disease
but not in other tumors. Very high levels of soluble IL2R (> or = 5000 U/ml) were significantly associated with a poorer treatment outcome in
Hodgkin disease
(p = 0.006) and retained significance in a multivariate analysis (p = 0.03). The addition of soluble IL2R measurements to existing prognostic models may improve risk assignment in children with
Hodgkin disease
.

Hodgkin's disease
(HD) is a heterogeneous condition with distinct histological and epidemiological subgroups. Recent data provide evidence that the Epstein-Barr virus (EBV) is associated with a significant proportion of cases. Clonal EBV genomes have been detected in affected tissues and EBV has been localised to RS cells. The significance of these findings is reinforced by the detection of the EBV latent gene product LMP-1, which has known transforming potential, within RS cells in EBV-associated cases. The age distribution of EBV-associated cases is non-random. Paediatric cases, particularly those aged < 10 years, are likely to be EBV-associated as are older adult cases. In contrast, a smaller proportion of young adult cases is EBV-associated, and nodular sclerosis HD cases within this age group are positive infrequently. The results of our studies provide support for the hypothesis that HD has multiple aetiologies but do not support the polio model. The epidemiological evidence suggesting that HD may have an infectious aetiology is strongest for the young adult age group. EBV was suggested as a candidate virus however it is in these cases that there is least evidence for involvement of EBV. It would seem plausible that another virus, possibly another common childhood infectious agent, is responsible for the incidence peak seen in this age group in developed countries.

Soluble forms of the two molecular species of the cell surface receptors (Rs) for tumor necrosis factor (TNF) have been detected in normal urine and serum including type I and type II TNF-Rs. Using enzyme-linked immunosorbent assay we have determined type I 60 kDa sTNF-R levels in the sera of 45 age- and sex-matched healthy subjects and 106 patients with
Hodgkin's disease
(HD). HD patients were either previously untreated (n = 76) or were in complete remission for at least 3 years after remission induction treatment (n = 30). The mean +/- SD concentrations of the 60 kDa type sTNF-R were significantly higher in HD patients than in healthy controls (1.32 +/- 0.19 ng/ml versus 0.6 +/- 0.13 ng/ml; p < 0.001). The extent of increase correlated with the disease stage. Soluble 60 KDa TNF-Rs were found to be significantly higher in stage III and IV (1.42 +/- 0.21 ng/ml) than in stages I and II (1.08 +/- 0.15 ng/ml). Patients with B-symptoms (n = 33) had higher levels (1.67 +/- 0.20 ng/ml) than patients without systemic symptoms (1.02 +/- 0.11 ng/ml; p < 0.001). In 52 patients evaluable for response, the complete remission (CR) rate of patients with 60 kDa sTNF-Rs < 1.2 ng/ml was higher (88%) than in those with 60 kDa sTNF-Rs > 1.2 ng/ml (64%; p < 0.01). A significant increase in serum levels of 60 kDa sTNF-R levels was also observed in HD patients in long-standing CR (1.04 +/- 0.10 ng/ml). Our data suggest that the pretreatment serum concentration of 60 kDa sTNF-Rs in HD may bear prognostic relevance. Increased 60 kDa sTNF-R levels seen in HD patients in remission may point to the defect in cellular immunity characteristic of HD patients.

The association of Epstein-Barr virus (EBV) with
Hodgkin's disease
(HD) and non-Hodgkin's lymphoma (NHL) was examined in Algerian patients. The DNA extracted from fresh lymph node biopsies of 17 HD and five NHL was analysed by polymerase chain reaction (PCR). Fifteen out of 17 biopsies (88%) from HD contained EBV genome. Viral type analysis showed the coexistence of A and B types of EBV in 14 biopsies (93%), and the sole presence of A type virus in one biopsy. Among five NHL biopsies examined, four biopsies contained both A and B types of EBV, while one revealed A type-virus only. This co-infection of Algerian HD and NHL patients does not seem to be related with any histologic form of these diseases. The analysis of viral types in the saliva from 12 Algerian healthy individuals revealed six EBV positives with only one A type. Two types of lymphoma in Algeria therefore are closely associated with EBV, and are characterized by coinfection with A and B types of EBV.

Lymphoma represents a major source of morbidity and mortality among AIDS patients. AIDS-associated non-
Hodgkin
lymphomas (AIDS-NHL) are almost invariably B-cell derived, are classified as high or intermediate grade lymphomas, and display three main histologic types: namely, small non-cleaved cell lymphoma (SNCCL), large cell immunoblastic plasmacytoid lymphoma (LC-IBPL), and large cell lymphoma (LCL). Here we report the in vitro establishment of three new AIDS-NHL cell lines (termed HBL-1, HBL-2, and HBL-3) derived from three AIDS-SNCCL patients differing in primary tumor sites and risk factors for HIV infection. The derivation of the cell lines from the original tumor clones was established by immunophenotypic and molecular genetic analysis. These cell lines display clonal immunoglobulin gene rearrangement, express surface immunoglobulin and B-cell restricted markers, and exhibit a phenotype consistent with SNCCL. Monoclonal Epstein-Barr virus infection was found in only one of the cell lines (HBL-1). Cytogenetic analysis demonstrated the presence of a chromosomal translocation involving the c-myc proto-oncogene and an immunoglobulin locus in all three cell lines. The pattern of genetic lesions detected in HBL-1, HBL-2, and HBL-3 reflects that found in primary AIDS-SNCCL and includes activation of the c-myc oncogene as well as inactivation of the p53 tumor suppressor gene. These cell lines should prove useful in studies of the biological, immunological, and viral factors involved in AIDS-associated lymphomagenesis.

The t(14;18) chromosomal translocation occurs in most follicular non-
Hodgkin
's lymphomas and places the Bcl-2 gene on chromosome 18q21 into the immunoglobulin JH region on chromosome 14q32. This translocation can be exploited to detect clonal malignant cells bearing this genetic alteration. A polymerase chain reaction (PCR) assay amplifying over the major breakpoint region (mbr) and minor cluster region (mcr) was developed and optimized. In this report, the sensitivity and reproducibility of this semiquantitative assay, performed on a relatively large number of clinical samples is shown. A titration curve of DNA made from a t(14;18)- cell line admixed with increasing ratios of a t(14;18)+ cell line was used to demonstrate that one t(14;18)+ cell in 100,000 t(14;18)- cells could reproducibly be detected. Occult lymphoma cells, not detected by standard morphologic analysis, were demonstrated in almost two-thirds of the bone marrow and peripheral blood specimens obtained from untreated patients with follicular lymphoma. Of 11 bone marrow samples assessed, seven were positive for occult disease by PCR amplification over the mbr and one was positive over the mcr. Of these six positive marrow samples, only three had been reported positive by standard morphologic criteria. In addition, seven of nine peripheral blood samples assessed were positive over the mbr and one additional sample was positive over the mcr. None of these were morphologically positive. Seven of the above patients would have been upstaged if these results were utilized for staging, including two of three patients with stage I or stage II disease. PCR-detectable occult disease persisted in four of four patients assessed both pre- and post-treatment, even after aggressive multi-drug combination chemotherapy in two of these patients. The clinical significance of detecting this occult disease must await the study of larger numbers of patients and the clinical outcomes of patients with occult disease and patients without occult disease.

The expression of the monocyte esterase was examined in a panel of 77 continuous human leukemia-lymphoma cell lines representing all hematopoietic cell lineages and in 16 other cell lines. Accumulation of mRNA, determined by Northern blotting with the cDNA probe HMSE-1, and production of the protein, shown by isoelectric focusing on polyacrylamide gels, correlated with differentiation of the cells along the monocytic lineage. None of the lymphoid, erythroid, megakaryoblastic or
Hodgkin's disease
derived cell lines or the non-hematopoietic human tumor cell lines expressed the full-length mRNA of 2.0 kb. These results support the notion that this enzyme, a serine hydrolase with still unknown physiological functions, is specifically expressed in cells committed to the monocyte/macrophage cell lineage.
