If the nadir ANC < 500/μL for 10 days or more, or if the nadir platelet count at every time falls below 25,000/μL, then the doses of etoposide, doxorubicin and cyclophosphamide are reduced by 20% below the doses used in the previous cycle, but doxorubicin and etoposide should not be reduced below the initial dose (dose in first course).

Diagram showing the relationship between the zenith, the nadir, and different types of horizon.

PSA levels may continue to decrease for several years after radiation therapy. The lowest level is referred to as the PSA nadir. A subsequent increase in PSA levels by 2.0 ng/mL [disputed – discuss] above the nadir is the currently accepted definition of prostate cancer recurrence after radiation therapy. [citation needed]
The TNM Classification of Malignant Tumors (TNM) is a globally recognised standard for classifying the anatomical extent of the spread of malignant tumours (cancer). It has gained wide international acceptance for many solid tumor cancers, but is not applicable to leukaemia or tumors of the central nervous system.
