[Chromosome changes on 20 lesions of cervix uteri ].
Cytogenetic studies on biopsies of cervix uteri (5 dysplasias, 2 carcinomas in situ and 13 invasive carcinomas) are reported in this paper in order to detect the numerical and structural chromosome changes. In dysplasias, the deviation number is mostly restricted around the diploid mode while in carcinomas the range of deviation is wider and more than one modal number could be identified. Structural aberrations of chromosome 1 were found in one case of dysplasia and in 10 cases of invasive carcinomas. A long acrocentric was observed in three carcinomas and one dysplasia, while a medium-sized metacentric in three carcinomas. Further markers : minute chromosomes (in two carcinomas) and double minute bodies (DMs, in one carcinoma). These studies and the early ones suggest that the changes of chromosome 1 may be a relative late appearance of malignant transformation. The possible role of DMs is also discussed.
