title: What is remission in follicular lymphoma and what is its relevance?
abstract: Follicular lymphoma (FL) is a unique disease characterised by a long natural history and responsiveness to many different therapies. We have reviewed the prognostic significance of the quality of both clinical and molecular responses for patients with FL. We have found that, as might be expected, patients who achieve a complete clinical response to treatment have a better prognosis than patients who achieve an incomplete or a partial response. However, unlike aggressive lymphomas, treatments that produce a higher frequency of complete responses do not result in better survival outcomes than treatments that produce lower complete response rates. Recent improvements in technologies have enabled quantitative monitoring of responses at the molecular level and at much higher degrees of sensitivity than can be obtained at the clinical level. Although these data are very heterogeneous and have many limitations, data are emerging that demonstrate that achieving molecular remissions after standard dose chemotherapy, high dose chemotherapy or various immunotherapies may have prognostic significance for patients with FL. With sensitive, quantitative, standardised and reproducible tools for molecular monitoring and with the combination of novel targeted biological therapies, we are approaching an era, where the potential to cure patients with FL is being turned into a reality.
