A historical perspective of registered cases of malignant ocular tumors in Zimbabwe (1990 to 1999). Is HIV infection a factor?

Introduction: Anecdotal and published reports suggest that ocular tumours are on the increase in Zimbabwe.

Objectives: To determine the trends in incidence rates of common malignant ocular tumours registered with the Zimbabwe Cancer Registry during the last decade (1990 to 1999).

Design: Retrospective study.

Aids and cancer in Africa: the evolving epidemic in Zimbabwe.

Background: Zimbabwe is severely affected by the AIDS epidemic, and many cancers in African populations are related to infectious agents.

Objective: To study the current pattern, and short-term changes in incidence, of cancers related to infectious agents (and especially to HIV), with respect to the evolving epidemic of AIDS.

Methods: Analysis of data on the African population of Harare, Zimbabwe, from the Zimbabwe Cancer Registry, for the period 1990-1995.

Cancer incidence in the African population of Harare, Zimbabwe: second results from the cancer registry 1993-1995.

The data of the population-based cancer registry in Harare, Zimbabwe, for 1993-1995 are presented and compared with those from 1990-1992. The most significant change in rates is the striking increase in the incidence of Kaposi's sarcoma (KS) in both men and women, compatible with the evolution of the AIDS epidemic in sub-Saharan Africa. The incidence of KS doubled in both sexes and now accounts for 31.

Cancer in the African population of Harare, Zimbabwe, 1990-1992.

The data presented from the population-based cancer registry in Harare, Zimbabwe, represent the first information on the incidence of cancer in Southern Africa for almost 20 years. In the African population in Zimbabwe there are several features in common with other countries in sub-Saharan Africa: high rates of liver, prostate and cervix cancer, low rates of large-bowel cancer and breast cancer. Also, as reported from southern and south-eastern Africa, there are relatively high incidence rates of cancers of the oesophagus, bladder and (in men) lung.

Cancer in the European population of Harare, Zimbabwe, 1990-1992.

The data presented from the population-based cancer registry in Harare, Zimbabwe, represent the first information on the incidence of cancer in a population of European origin living in Southern Africa for over 30 years. Their cancer pattern is more or less typical of white populations of high socio-economic status living in Europe or North America, with elevated incidence rates of breast cancer, large-bowel cancer and, in women, lung cancer. However, there are also several unusual features, with extremely high incidence rates of skin cancers, including melanomas, and higher rates of liver and bladder cancer than normally seen in white populations.
