Cancer chemotherapy is based on an understanding of tumor cell growth and of how drugs affect this growth. After cells divide, they enter a period of growth (ie, phase G1), followed by DNA synthesis (ie, phase S). The next phase is a premitotic phase (ie, G2), then finally a mitotic cell division (ie, phase M).

Cell-division rates vary for different tumors. Most common cancers grow slowly compared with normal tissues, and the growth rate may be decreased in large tumors. This difference allows normal cells to recover more quickly than malignant ones after chemotherapy and is the rationale behind current cyclic dosage schedules.
