[Cervical cancers diagnosed at the Pasteur Institute of Madagascar from 1992 to 2002].

In Madagascar, the epidemiological data actualized concerning the cancer of the collus of uterus are not available because of the absence of register of cancer. The objective of this study is to achieve a first assessment of the problem, to complete the epidemiological knowledge, to point out the tool of precoce detection of the precancerous lesions, to propose the measures aiming to improve the management of the patients and to contribute to the institution of a register of cancer. This is a retrospective survey on the frequency of the cancer of the cervix observed from 1992 to 2002 about 23,908 withdrawals addressed to the Institut Pasteur de Madagascar for anatomopathological exam and 12,605 cervical smears for cytological exam. In pathological anatomy, 2,621 (63.4%) of 4,136 cases of diagnosed cancer, have been observed in women. 687 cases (26.2%) of them were localized in the collus. The 3/4 of the cancers of the cervix is invasive and the mean age is 48.2 years old at the time of diagnosis. The cytology detects only 74 cases of invasive cancer of which most don't have an histological confirmation. 274 pre-lesions of cervix cancer were diagnosed for this period, the majority lesions are cytological diagnosis. In spite of a non representative recruitment of the general population, and by the number of withdrawals considered, these results may represent indicators of the epidemiological situation and justify the institution of program to detect the precancerous lesions in a national scale.
