[Mitotic conditions in primary and metastatic nodes of breast and cervix cancer]

The results of the study on the mitotic regimen (mitotic activity ratios of mitosis phases and percent of pathological mitoses) in primary and metastatic nodes of the tumour by the example of mammary gland and cervical carcinoma are presented. A similarity in the mitotic regimen in primary and metastatic nodes of the tumour was observed which was manifested in a high level of mitotic activity predominance of metaphases over other phases of mitosis, the occurrence of similar pathological forms of mitosis. The difference between the mitotic regimen in the primary and metastatic nodes consisted in an increase in the latter of the number of pathological mitoses mostly at the expence of K-mitoses. Three-group metaphase typical of cervical carcinoma was found in all metastatic nodes of the squamous cell carcinoma of the cervix and may probably serve as a peculiar "marker" of tumours of this localization.
