Haematological Malignancy Prognosis
Every haematological malignancy prognosis calculator on CalcEngines — unit converters, derived indices and interpretive tools, each with its formula, a worked example and the reference intervals it is judged against.
8 calculators in this section
- CML Risk Scores: Sokal, Hasford, EUTOS, ELTSFour published scores on one patient. They use different variables, different formulas and different scales, they classify the same patient into different risk groups, and the published agreement between Sokal and the other two is poor. The ELN 2020 panel recommends the ELTS score instead of the older three.
- DIPSS Calculator for MyelofibrosisFive risk factors, and anaemia is the only one worth two points — the change that turned the fixed-at-diagnosis IPSS for myelofibrosis into a score that can be applied at any point in the illness.
- FLIPI Calculator for Follicular LymphomaFive adverse factors, one point each. FLIPI was built on patients diagnosed between 1985 and 1992 — before rituximab existed — which is the entire reason FLIPI-2 was later developed, and the reason its survival figures are a historical measurement rather than a forecast.
- FLIPI-2 Calculator for Follicular LymphomaFLIPI-2 keeps age and haemoglobin, swaps LDH for beta-2 microglobulin and the nodal count for the largest node's diameter, and adds marrow involvement. Built on prospectively collected rituximab-era data, and it predicts progression-free survival rather than overall survival.
- IPSS-R Calculator for Myelodysplastic SyndromeFive weighted items to a total of 0 to 10, and the weights are FRACTIONAL: platelets and neutrophils can score 0.5 and haemoglobin 1.5, so an implementation that rounds moves a patient across a stratum boundary silently.
- MIPI Calculator for Mantle Cell LymphomaMIPI is NOT a points score. It is a continuous linear predictor in age, performance status, the LDH ratio and the logarithm of the white cell count, with published coefficients, banded afterwards — so a one-year change in age moves it, which no sum can do.
- NCCN-IPI Calculator for DLBCLThe refined IPI: age in four bands, the LDH ratio in three, and a restricted list of extranodal sites, to a maximum of 8 points. The LDH term is a RATIO to the laboratory's own upper limit of normal, which is why this index cannot be computed from an absolute LDH.
- R-IPI Calculator for DLBCLThe revised IPI changes no factor and no weight. It redistributes the same five points of the 1993 index into three strata instead of four, because R-CHOP collapsed the difference between the two middle groups the original index separated.
