In pursuit of a functional cure for follicular lymphoma.

We are now a quarter of a century after the transformative impact of rituximab in improving overall survival for patients with follicular lymphoma. With a burgeoning array of effective immunochemotherapy approaches, we can now frame many patients' expectations of longevity and a "functional cure," with survival estimates for many newly diagnosed patients comparable to age- and gender-matched populations. We highlight not just heterogeneity in disease but also in patients, which influences therapeutic decision-making in an immunochemotherapy era where progression-free survival advances are associated with efficacy-toxicity trade-offs, and no clear overall survival advantage is associated with any specific regimen. We provide the metrics that assist, prognostication both at diagnosis and after initial therapy, but we also highlight the limited long-term follow-up in institutional, population, and clinical trial data sets to inform our survival estimates. Nonetheless, the data are sufficient to empower us to reframe more optimistic conversations with our patients and the lymphoma community, discussions that engender hope and planning for a life lived long, and well, after therapy for follicular lymphoma.
