The S-phase index is a measure of the percentage of cells in a tumor that are actively dividing (in S-phase of the cell cycle). A low S-phase index indicates that very few cells are dividing, which is characteristic of certain slow-growing cancers. Therefore, it is likely that the oncologist used the S-phase index to determine that the client's cancer is slow-growing.
