Follicular Lymphoma International Prognostic Index (FLIPI)

Additional Information

Score Description

The Follicular Lymphoma International Prognostic Index (FLIPI) is a prognostic index for patients with follicular lymphoma. The FLIPI is a modified version of the International prognostic index (IPI) that was originally developed in patients with clinically aggressive non-Hodgkin lymphomas. The FLIPI was devised based on an international study of long-term survival in 4167 patients with follicular lymphoma diagnosed between 1985 and 1992. Patients who were treated received a range of chemotherapies, none including rituximab. However, the FLIPI still retains prognostic relevance in the era of rituximab.
