How to Use DLBCL Prognosis Calculator
The DLBCL Prognosis Calculator applies five International Prognostic Index factors. Enter age, Ann Arbor stage, whether LDH is elevated, ECOG performance status, and the number of extranodal sites. The calculator adds one point for each adverse factor and displays the IPI score, risk group, and estimated 5-year survival reference.
The input choices mirror the components commonly discussed in DLBCL risk stratification. A user can change one factor at a time to see how age over 60, stage III/IV disease, elevated LDH, ECOG 2 or higher, or more than one extranodal site affects the total score.
This page is educational. Prognosis in DLBCL also depends on pathology, molecular features, treatment regimen, response to therapy, relapse status, comorbidities, access to care, and newer risk models. The result should never be used to make treatment decisions without an oncology team.
Formula & Theory - DLBCL Prognosis Calculator
The DLBCL Prognosis Calculator uses:
IPI score =
(age > 60) +
(Ann Arbor stage III or IV) +
(LDH elevated) +
(ECOG performance status >= 2) +
(extranodal sites > 1)Each true condition adds 1 point, giving a total score from 0 to 5. The calculator maps the score to risk groups:
0-1 points: low risk
2 points: low-intermediate risk
3 points: high-intermediate risk
4-5 points: high riskApproximate survival percentages are shown as historical educational references.
Use Cases for DLBCL Prognosis Calculator
The DLBCL Prognosis Calculator is useful for oncology education, explaining IPI components, reviewing case examples, and preparing structured questions for a hematology or oncology visit.
It can help learners understand why the same diagnosis may carry different risk categories. For patient counseling, always rely on the treating oncology team and the most relevant contemporary clinical data.
