title: Heteromorphisms of C-bands in patients with precancerous and cancerous lesions of the cervix uteri.
abstract: C-band heteromorphisms of chromosomes 1, 9 and 16 were studied in 62 patients with cervical cancer, 100 women with various grades of precancerous lesions and 47 normal women as controls. The data showed an increased frequency of heteromorphisms of chromosome 1 in patients with cancer (48.39%) and severe dysplasias (40%) as compared to controls (29.8%) and lower grades of dysplastic lesions, i.e. mild and moderate (28.8%). The increase in the incidence of chromosome 1 heteromorphisms in cancer was found to be statistically significant (p less than 0.05) compared to controls. The present study indicates that C-band heteromorphisms may play some role in the development of malignancy of the uterine cervix.
