Simplicity at the cost of predictive accuracy in diffuse large B-cell lymphoma : A critical assessment of the R-IPI, IPI, and NCCN-IPI
The international prognostic index (IPI) and similar models form the cornerstone of clinical assessment in newly diagnosed diffuse large B-cell lymphoma (DLBCL). While being simple and convenient to use, their inadequate use of the available clinical data is a major weakness. In this study, we compared performance of the International Prognostic Index (IPI) and its variations (R-IPI and NCCN-IPI)
