Background: Hodgkin’s lymphoma is a distinct primary solid tumor of the immune system that shows wide variation in incidence among different geographic regions and among various races. It was previously suggested that susceptible people living in certain parts of Israel had a higher risk of HL[1] because of exposure to unidentified environmental factors in these regions. Compared with other parts of Israel, these regions were characterized by a higher proportion of Israeli-born Jews.

Objectives: To study time trends in the incidence rate of HL in Israeli-born Jews of all age groups during the years 1960–2005.

Results: A total of 4812 Jewish cases of HL were reported to the Israel Cancer Registry during the study period 1960–2005. There has been a persistent increase in the age-standardized incidence rate of HL, all subtypes pooled, in Israeli-born Jews in both men and women. The age distribution pattern in both genders was bimodal in all periods. The highest incidence was observed in the 20–24 year age group: for women (9.13 per 100,000 per year) during the period 1988–1996, and for men (6.60 per 100,000 per year) during the period 1997–2005.

Conclusions: The reported incidence level of HL in Israeli-born young adult Jews in Israel has increased in recent years to high levels compared with other western countries. Our findings suggest a cohort effect to unidentified factors affecting Israeli-born young adult Jews in Israel.

Background: A previous study on Hodgkin's lymphoma in southern Israel found that Bedouin patients had an increased rate of Epstein-Barr virus expression in their tumor cells.

Objectives: To determine the influence of the patients' communities on the pattern of disease in HL.

Methods: We compared the clinical features, demographic data, stage at diagnosis, treatment modality and outcome, as well as laboratory findings, in four community-based subgroups. These groups comprised kibbutz residents (n=11), Bedouin (n=19), new immigrants from the former USSR (n=22), and town-dwellers (n=82).

Results: The Bedouin patients differed significantly from the new immigrants and town-dwellers, particularly regarding the rate of EBV sequences in the tumor tissues, and a poorer response to treatment. The kibbutz patients did not differ significantly from the other populations regarding most of the parameters studied, but showed an intermediate expression of EBV antigens compared to Bedouin patients and the rest of the cohort.

Conclusions: This study indicates that HL may behave differently in different population groups in a given geographic area. Notably, the Bedouin patients showed markedly different clinical and biological patterns of this malignancy.
