A five-point score (age, stage, performance status, LDH, extranodal sites) that predicts how risky a lymphoma is before treatment.
The International Prognostic Index is a five-point score for aggressive lymphoma that counts age, stage, performance status, LDH and extranodal involvement, and is calculated before treatment begins. Scores of 0 to 1 are low risk, 2 low-intermediate, 3 high-intermediate and 4 to 5 high risk. In diffuse large B-cell lymphoma the IPI defines trial eligibility, with POLARIX enrolling patients scoring 2 to 5 and frontMIND those scoring 3 to 5, and it frames the expected outcome of R-CHOP, which is far better at the low end of the scale than at the high end in the rituximab era. Readers meet it on the DLBCL page and in those two trial records.
Leukaemias, myeloma and MDS live in the marrow and blood; lymphomas grow in lymph nodes and spleen. The node stations are the disease map, not a route of spread, and staging counts them.
In lymphoma the node stations are the disease itself; staging (Ann Arbor / Lugano) counts how many regions and sides of the diaphragm are involved.

Showing the organ this term concerns: Diffuse large B-cell lymphoma.
The reason second-line CAR-T is offered with axicabtagene ciloleucel or lisocabtagene maraleucel rather than tisagenlecleucel. The trial is also the strongest evidence in the field that the interval between apheresis and infusion, and what is given during it, is part of the treatment rather than logistics around it.
One of the two foundational genetic classifications of diffuse large B-cell lymphoma. Neither has yet changed what a patient receives outside a trial, but together they are the reason precision-medicine trials in this disease now select by genetics rather than by cell of origin.
The practical form of cell-of-origin classification, used in pathology laboratories worldwide. When a report says germinal-centre or non-germinal-centre, this is almost always the algorithm behind it.
The reason a pathology report on diffuse large B-cell lymphoma says germinal-centre or non-germinal-centre, and the origin of every attempt since to treat the two differently. It also made the case that microarray profiling could do something the clinical index could not, which is what pulled genomics into haematology.
