[Cancer in Madagascar. Experience of the Institut Pasteur de Madagascar from September 1992 to June 1996].
The Unit of the anatomo-pathology in the "Institut Pasteur de Madagascar" (IPM) examined in the period from September 1992 to June 1996 tissue specimens from 10,275 patients. Tumorous pathology presented 40% of the tissues and half of which were of malign etiology. 64% of the cancer diagnosed were in females. Cervical cancer was most frequently observed (17%), followed by breast cancer (16%). Cancer in the gastro-intestinal tract (15%) was most often located in the colon without sex difference. Stomach cancer occurring predominantly in males presented 25% of the total cases of cancer in the gastro-intestinal tract. Cancer of liver is rarely diagnosed despite the high prevalence of infection with hepatitis B virus. Skin cancer constituted 9% of the malign diagnosis and was mainly found in males. Children under 15 years old presented 7.4% of the total cases of malignancy with the haematopoietic tissues (30%) and the eyes (17%) as the most frequent topic locations. Due to a very low seroprevalence of the HIV in Madagascar, malign tumours associated to AIDS were only seen in a few rare cases. The review of cancer cases in the IPM may not be representative for the cancer epidemiology of Madagascar because of a general very low level of health care coverage, especially in the rural areas. Furthermore, a major part of the specimens originates from easily accessible organsystems, whereas other organs seem less investigated due to lack of appropriate available technique. Therefore, it is not feasible for the moment to establish a cancer register in Madagascar, although the Unit of Pathology in the IPM can offer a valid cancer diagnostical service.
