Cancer patterns in Jordan 1975-1979

A total of 3,604 primary malignant tumours diagnosed histologically at the Departments of Pathology in Jordan during the period 1975-1979 were analysed. The relative frequency by age, sex and site of these tumours and age-standardised incidence rate are presented. Truncated standardised incidence rates for selected tumours were compared in Jordan and other countries. Except for the urinary bladder tumours, there is a striking resemblance between Jordan and other Middle Eastern countries in the pattern of tumour-occurrence in most sites. Skin malignancies are the dominant tumours in the general and male population, breast in female population and lymphomas in children. Noteworthy are the histologically advanced bladder cancers and the relatively young females affected by breast cancer at first diagnosis. Childhood tumours comprised 7.4% of the total cancers in the present study.
