WebAug 2, 2024 · Mitotic phases Mitosis takes place in 4 distinct yet continuous phases: prophase, metaphase, anaphase, and telophase. Cytokinesis overlaps with the later stages of mitosis to compete the mitotic phase. The mitotic phase results in the formation of 2 genetically identical daughter cells. WebMitotic activity may also be used as a predictor of the ability of thin melanomas to metastasize. 8 In recent melanoma staging systems, a single mitosis per square millimeter is considered important, and can upstage thin melanomas from pT1a to pT1b. 9 Finally, interobserver agreement for melanoma mitotic rate has been shown to be excellent. 10
