Childhood malignant tumours in Papua New Guinea.
Data from the Papua New Guinea Tumour Registry and the Central Pathology Department were reviewed in order to document the incidence and pattern of malignancies in children in Papua New Guinea. Altogether, 680 cases of histologically defined childhood malignancies were recorded during the 14.5 years from 1971 to 1985. The frequencies of the various tumours were compared with past data and with published data from other countries. The incidence of malignancies in Papua New Guinean children appeared to be low, 36.5/1,000,000/year, with a male:female ratio of 1.6:1. Lymphoma was the most commonly occurring tumour and Burkitt's tumour accounted for 53% in this group. The relative frequency of leukaemia compared with lymphoma appeared to have increased since a previous report. A relatively high incidence of retinoblastoma (6.9%) and of other embryonal tumours (4.8%) was recorded, whilst the recorded incidences of tumours of the central nervous system (3.8%) and neuroblastoma (3.7%) were low. Ewing's sarcoma accounted for almost half of the bone tumours, whilst Kaposi's sarcoma was a relatively frequent soft tissue tumour. Differences and similarities between the Papua New Guinea data and those from other countries are discussed.
