Doubling Time, Doubling Rate & Progression Calculator

The Doubling Time, Doubling Rate & Progression Calculator can be used for the following purposes:

    1. Calculation of tumor marker – doubling time and doubling rate.
      To calculate tumor marker – doubling time and doubling rate with the data of serial measurements of a serum tumor marker.
    2. Calculation of tumor volume – doubling time and doubling rate
      To calculate tumor volume – doubling time and doubling rate with the data of serial measurements of tumor sizes.
    3. Estimation of time for progression
      To estimate the time (T) for a tumor with a known doubling time (DT) or doubling rate (DR) of size A to grow to size B.
      If you input DT or DR, A, and B, the calculator gives T.
    4. Estimation of progression over time
      To estimate the time D after a given time (T) of a tumor of size C with a known doubling time (DT) or doubling rate (DR).
    5. If you input DT or DR, C, and T, the calculator gives D.
