NCI Scientists Create Model That Predicts Follicular Lymphoma Survival Scientists at the National Cancer Institute (NCI), part of the National Institutes of Health, have created a model that predicts the survival of follicular lymphoma patients based on the molecular characteristics of their tumors at diagnosis. The model is based on two sets of genes--called survival-associated signatures--whose activity was found to be associated with good or poor prognosis for patients with the cancer.
