The International Prognostic Index (IPI) is a clinical tool developed by oncologists to aid in predicting the prognosis of patients with aggressive non-Hodgkin's lymphoma. Previous to IPI's development, the primary consideration in assessing prognosis was the Ann Arbor stage alone, but this was increasingly found to be an inadequate means of predicting survival outcomes, and so other factors were studied.

  • Der Internationale Prognostische Index (IPI) ist ein klinisches Scoring-System in der Onkologie, das 1993 entwickelt wurde, um die Prognose von Patienten mit malignen Non-Hodgkin-Lymphomen abschätzen zu können.Der Score beruht auf der retrospektiven Analyse der Krankheitsverläufe von 2031 Non-Hodgkin-Lymphom-Patienten, die im Zeitraum von 1982 bis 1987 mit einer Doxorubicin-basierten Chemotherapie (wie zum Beispiel dem CHOP-Schema) behandelt worden waren. Aktuelle Leitlinien wie die Leitlinien Maligne Lymphome der DGHO differenzieren die Empfehlungen zur Chemotherapie und zur Antikörpertherapie nach dem INI-Score. (de)

  • The International Prognostic Index (IPI) is a clinical tool developed by oncologists to aid in predicting the prognosis of patients with aggressive non-Hodgkin's lymphoma. Previous to IPI's development, the primary consideration in assessing prognosis was the Ann Arbor stage alone, but this was increasingly found to be an inadequate means of predicting survival outcomes, and so other factors were studied. In 1984, the first prognostic indicator for advanced non-Hodkin's lymphoma was developed. An information theory guided, computer search and evaluation procedure was employed to discover the largest sub-groupings for which survival is as extreme as possible In the clinical trials analyzed retrospectively and containing a large fraction of patients not matching the 'good' - of 'good' (Karnofsky status >80 and 'A" Symptoms and SGOT <36 U/L), 'poor' (Karnofsky status <70 or Night sweats) and 'intermediate' (All Remaining) prognosis patterns identified, a significant difference was found between the survival of patients with and those without a complete response to therapy. The authors concluded that trials using a patient mix weighted toward good prognosis will not find such a difference. In 1993, a retrospective analysis was performed on 2031 patients with aggressive non-Hodgkin's lymphoma, of all ages, treated with a doxorubicin-based chemotherapy regimen such as CHOP between 1982 and 1987. Several patient characteristics were analyzed to determine whether they were associated with differences in survival, and the factors that emerged as significant were, in addition to the Ann Arbor stage: age, elevated serum lactate dehydrogenase (LDH), performance status, and number of extranodal sites of disease.
