SAN ANTONIO—A new study indicates that patients with early stage follicular lymphoma (FL) are increasingly receiving no treatment or single-agent chemotherapy, despite evidence suggesting that radiation therapy can produce better outcomes.
Guidelines from the National Comprehensive Cancer Network and the European Society for Medical Oncology both list radiation therapy as the preferred treatment for low-grade FL.
However, investigators found that, in recent years, radiation has been replaced by alternative strategies.
“Our study highlights the increasing omission of radiation therapy in [FL] and its associated negative effect on overall survival at a national level,” said John Austin Vargo, MD, of the University of Pittsburg Cancer Institute in Pennsylvania.
“This increasing bias towards the omission of radiation therapy is despite proven efficacy and increasing adoption of lower radiation therapy doses and more modern radiation therapy techniques which decrease risk of side effects.”
Dr Vargo presented these findings at the 57th Annual Meeting of the American Society for Radiation Oncology (presentation #183).
He and his colleagues analyzed patterns of care and survival outcomes for 35,961 patients diagnosed with early stage FL as listed in the National Cancer Data Base. A majority of patients were older than 60 (61%), and most had stage I disease (63%).
The use of radiation therapy in this group of patients decreased from 37% in 1999 to 24% in 2012 (P<0.0001).
The use of observation increased from 34% in 1998 to 44% in 2012 (P<0.0001). And the use of single-agent chemotherapy increased from 5.4% in 1999 to 11.7% in 2006 (P=0.01).
The 5-year overall survival rate was 86% in patients who received radiation and 74% in those who did not (P<0.0001). Ten-year overall survival rates were 68% and 54%, respectively (P<0.0001).
In multivariate analysis, radiation therapy remained significantly associated with improved overall survival (P<0.0001).
