Lymphocyte count threshold for diagnosis

This slide calculates the likely time from being diagnosed with CLL to the commencement of formal treatment for CLL, based on lymphocyte count at diagnosis.

The time from diagnosis to treatment is started is often called the “watch and wait” period. This can be a very stressful time.
This slide uses the patient’s lymphocyte count at diagnosis to predict when treatment with medications will likely start.
The horizontal axis is months from time of diagnosis until treatment with medications is likely to start, and the vertical axis is how likely the patient is at a certain number of months after diagnosis to be on treatment (0.0 = no chance, 1.0 = certain to be having treatment). So if the patient’s lymphocyte count at diagnosis is greater than 15b/L, they have about a 50% chance of being started on treatment 50 months after diagnosis.
