The International Prognostic Index (IPI), which was originally designed as a prognostic factor model for aggressive non-Hodgkin lymphoma, also appears to be useful for predicting the outcome of patients with low-grade lymphoma. This index is also used to identify patients at high risk of relapse, based on specific sites of involvement, including bone marrow, central nervous system, liver, testis, lung, and spleen. [8] Separate indices have been developed for follicular and mantle cell lymphoma. [9, 10, 11]
