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.

One thousand and sixty-three twins with cancer whose co-twin was born alive were identified among patients born since September 1939 with cancers incident in England and Wales during 1971-1984 at childhood and young adult ages. Site-specific risks of cancer were analysed in relation to birth order within the twinship and sexes of the twin pair, using adjusted national birth data to give control distributions of these variables. Risk of leukaemia was increased in first-born twins, risk of testicular cancer was increased in second-born twins with female co-twins but decreased in second-born twins with male co-twins and lung cancer risk was increased in first-born twins with same-sex co-twins. Cutaneous melanoma risk was increased in persons with opposite-sex co-twins, nervous system cancer risk was increased in females with opposite-sex co-twins and Hodgkin's disease risk was increased in persons with same-sex co-twins. For most of the findings, no previous comparable analyses are available, so interpretation of the results must be provisional until the analyses can be repeated on other data. The result for leukaemia would accord with previous suggestions that leukaemia may be of prenatal origin and may sometimes lead to intrauterine death. The Hodgkin's disease result would fit with theories of an infectious aetiology, and this view is strengthened by reanalysis of previous data on paralytic poliomyelitis in twins, which show a pattern similar to that for the Hodgkin's disease patients. Cancer risk in relation to birth order and sex of twins can give novel, objective data relating to prenatal and infectious disease aetiology of cancers.

The relationship between a history of selected medical conditions and risk of lymphomas was investigated in a hospital-based case-control study conducted in Northern Italy on 429 incident, histologically confirmed cases of non-Hodgkin's lymphoma (NHL), 158 cases of Hodgkin's disease (HD) and 1157 controls admitted to hospitals for acute conditions. The odds ratios (OR) for NHL were above unity in patients with a history of infectious mononucleosis (OR 2.9), herpes zoster (OR 1.8), pyelonephritis (OR 4.9), tuberculosis (OR 1.8), malaria (OR 1.9), any chronic bacterial diseases (OR 1.7), rheumatoid arthritis (OR 1.7) and psoriasis (OR 2.5). With reference to HD, the ORs were 4.0 for infectious mononucleosis, 2.9 for herpes zoster, 3.3 for pyelonephritis, 2.3 for tuberculosis, 1.4 for chronic bacterial diseases, 2.4 for rheumatoid arthritis, 2.7 for psoriasis and 2.1 for diabetes. The association of NHL and HD with herpes zoster was restricted to the first ten years since the onset of the disease. The relationships between NHL and mononucleosis (OR 12.9), malaria (OR 2.8) and psoriasis (OR 14.0) were stronger for cases aged > or = 60 years, and that with tuberculosis (OR 3.5) was stronger for younger cases. For HD, the positive association was stronger for cases aged > or = 40 years for herpes zoster (OR 3.8) and diabetes (OR 2.6). An increased risk of NHL was found in association with poliomyelitis (OR 1.6) (restricted to cases aged > or = 60 years, OR 4.0) and BCG immunizations (OR 1.6), but not with vaccination against smallpox, tetanus and diphtheria; increased risks of HD were found in relation to poliomyelitis and BCG immunization in cases aged > or = 40 years (OR respectively 2.5 and 2.1), or > or = 50 years (OR 4.3 and 2.2). Thus, our results confirm the association between a history of several chronic infectious and inflammatory diseases and the risk of NHL or HD, and are compatible with a role of chronic immunological alterations in the aetiology of lymphomas.

Between 1955 and 1963, an estimated number of 150 million people in various parts of the world, including Norway, received poliomyelitis vaccine possibly contaminated with infectious simian virus 40 (SV40). Human studies have investigated the hypothesised association between SV40 and various cancers, but the results have so far been contradicting. The aim of the present study was to examine Norwegian cancer incidence data to assess a possible association between birth cohorts assumed to have been subjected to the vaccine and the incidence rate of lymphoproliferative disorders (excluding Hodgkin's lymphoma), further subdivided into non-Hodgkin's lymphoma (NHL), lymphocytic leukemia and plasma cell neoplasms. Between 1953 and 1997, the incidence rate of lymphoproliferative diseases combined increased about 3-fold in both males and females. Subgroup analysis showed that this increase was largely attributable to NHL. Age-period-cohort modelling of the subgroups, as well as of all groups combined, showed that the cohort effect was more prominent than the period effect. However, the variations in incidence patterns across the birth cohorts did not fit with the trends that would be expected if a SV40 contaminated vaccine did play a causative role. Thus, our data do not support the hypothesis of an association between the vaccine and any subgroup of lymphoproliferative diseases.
