Radiotherapy with rituximab may be better than radiotherapy alone in first-line treatment of early-stage follicular lymphoma: Is it time to change the standard strategy?
Abstract
Early-stage follicular lymphoma (FL) has traditionally been treated with involved-field radiotherapy (RT). Rituximab (R) is a low-toxic, efficient systemic therapy for FL, but there are no data about its clinical impact in early FL.
We retrospectively analyzed 93 patients with stage I-II indolent FL treated with RT (n = 65) or RT + R (n = 14) or R alone (n = 14). Median follow-up was 5.0 years for patients with RT, 2.8 years for the RT + R subgroup and 2.5 years for patients treated with R.
The complete response rate was 92%, 100% and 86% (not significant) and the median PFS was 3.3 years, not reached and 4.9 years (p = 0.035) for the RT, RT + R and R arms, with no impact on overall survival. R combined with RT seems to give better results in terms of global FL control, but longer follow-up and prospective comparison are needed to verify these results.
