MIPI Score Calculator

MIPI Score Calculator for Hematology. Continuous MIPI uses <5.7, 5.7 through <6.2 and >=6.2 risk groups. Using 9.5 instead of 9500 for WBC changes the score by 2.8179; units must match the label. This is not simplified MIPI or MIPI-c.

For shared guidance on choosing a tool and documenting results, read the clinical calculator workflow.

How this calculator works

MIPI = 0.03535 x age + 0.6978 x indicator(ECOG >=2) + 1.367 log10(LDH/ULN) + 0.9393 log10(WBC in cells/microliter). Cutoffs are <5.7, 5.7 through <6.2 and >=6.2.

When to use this calculator

Use for original continuous MIPI prognostic description in mantle cell lymphoma, with documented ECOG grade and laboratory LDH upper limit. Enter WBC in cells/microliter exactly as labeled; it is not a treatment selector.

Inputs used

  • Age (completed years)
  • Documented ECOG performance-status grade
  • LDH (U/L)
  • Laboratory LDH upper limit (U/L)
  • WBC (cells/microliter; not 10^9/L)

Clinical interpretation

Continuous MIPI uses <5.7, 5.7 through <6.2 and >=6.2 risk groups. Using 9.5 instead of 9500 for WBC changes the score by 2.8179; units must match the label. This is not simplified MIPI or MIPI-c.

Worked example

Fictional teaching case. Age (completed years): 68; Documented ECOG performance-status grade: 0; LDH (U/L): 320; Laboratory LDH upper limit (U/L): 250; WBC (cells/microliter; not 10^9/L): 9500. Result: 6.286632. Original MIPI high-risk group. This is a risk estimate, not a diagnosis, a personal survival prediction, or an automatic treatment/discharge decision. This is original continuous MIPI, not simplified MIPI or MIPI-c; Ki-67 is not included.

Limitations and safety notes

For mantle cell lymphoma. Enter the documented ECOG integer grade from an authorized assessment; no questionnaire is reproduced. Logarithm inputs must be positive. Modern treatments and selected patient groups affect prognostic calibration.

Frequently asked questions

Can I fix the result by entering a different WBC unit without changing the label?

No. Enter WBC in cells/microliter as labeled. A laboratory result of 9.5 x 10^9/L corresponds to 9500 cells/microliter; the tool must not receive 9.5 under this label.

What can change the meaning of this result?

For mantle cell lymphoma. Enter the documented ECOG integer grade from an authorized assessment; no questionnaire is reproduced. Logarithm inputs must be positive. Modern treatments and selected patient groups affect prognostic calibration.
