title: [Morphologic criteria for the initial forms of stage Ia invasive cancer of the cervix uteri].
abstract: Morphological study was carried out on biopsy and operation materials from 107 patients with initial forms of cervical cancer. The initial forms of cancer include lesions suspect for infiltrative cancer, and infiltrative cancer with the depth of invasion not more than 3 mm. The condition of the stroma in initial invasion which is considered to be a defence reaction is described in detail. In 85% of the patients the infiltrative cancer developed against the background of carcinoma in situ, in 15% against the background of dysplasia. The authors believe that the morphological features of the initial invasive forms are sufficient for distinguishing them as a separate stage Ia.
