In follicular lymphoma (FL), no prognostic index has been built based solely on a cohort of patients treated with initial immunochemotherapy. There is currently a need to define parsimonious clinical models for trial stratification and to add on biomolecular factors. Here, we confirmed the validity of both the follicular lymphoma international prognostic index (FLIPI) and the FLIPI2 in the large prospective PRIMA trial cohort of 1135 patients treated with initial R-chemotherapy ± R maintenance. Furthermore, we developed a new prognostic tool comprising only 2 simple parameters (bone marrow involvement and β2-microglobulin [β2m]) to predict progression-free survival (PFS). The final simplified score, called the PRIMA-PI (PRIMA-prognostic index), comprised 3 risk categories: high (β2m > 3 mg/L), low (β2m ≤ 3 mg/L without bone marrow involvement), and intermediate (β2m ≤ 3 mg/L with bone marrow involvement). Five-year PFS rates were 69%, 55%, and 37% in the low-, intermediate-, and high-risk groups, respectively (P < .0001). In addition, achieving event-free survival (EFS) or not at 24 months (EFS24) was a strong posttreatment prognostic parameter for subsequent overall survival, and the PRIMA-PI was correlated with EFS24. The results were confirmed in a pooled external validation cohort of 479 patients from the FL2000 LYSA trial and the University of Iowa/Mayo Clinic Lymphoma Specialized Program of Research Excellence Molecular Epidemiology Resource. Five-year EFS in the validation cohort was 77%, 57%, and 44% in the PRIMA-PI low-, intermediate-, and high-risk groups, respectively (P < .0001). The PRIMA-PI is a novel and easy-to-compute prognostic index for patients initially treated with immunochemotherapy. This could serve as a basis for building more sophisticated and integrated biomolecular scores.

An adverse prognostic impact of statin use in lymphoma was first suspected from in vitro data showing an impairment of anti-CD20 antibody binding. However, further clinical studies suggested an improved outcome associated with their use in hematological malignancies. In particular, a survival benefit was reported for patients with follicular lymphoma on statins. Our objective was to assess the outcome of follicular lymphoma patients treated in the PRIMA study with immunochemotherapy according to the use of statins. Among the 1,217 patients enrolled in the PRIMA study, 1,135 were included in the present study. Concomitant treatments at registration were available for all patients. Among those 1,135 patients, 119 were on statins (10.5%) at diagnosis. Adverse events frequencies, event-free survival (EFS), time to next lymphoma treatment (TTNLT), time to next chemotherapy (TTNCT), and overall survival (OS) were evaluated according to the use of statins. The rates of overall and specific cardiovascular adverse events between the two groups of patients were comparable both during induction and maintenance. Outcome in terms of response rates or EFS, TTNLT, TTNCT, and OS were similar regardless of the use of statins (P = 0.57, P = 0.85, P = 0.30, and P = 0.43, respectively) in univariate analysis and after further adjustments for potential confounding factors in multivariate analysis. In conclusion, statin use does not impact the prognosis of patients with follicular lymphoma treated with immunochemotherapy.
