The research underlines the fact that when cancer strikes, modern patients and their oncologists across the United States are taking many diverse treatment paths when there is scant data to support one method over another.
This study suggests that the old standard approach – radiation therapy, alone – is no longer the best choice for early follicular lymphoma, according to researchers at the James P. Wilmot Cancer Center at URMC.
Lead author Doctor Jonathan W. Friedberg pointed out that the earlier recommendation for radiation was based on uncontrolled experiences at select institutions.
“As we move into an era focused on quality, we need research like this to help us determine the true effectiveness of various therapies when definitive studies are lacking,” Friedberg said. “The choice of treatment should be based on whether it produces remission and survival. And if the outcomes are equivalent, then we’ll need to consider toxicities and tolerance of therapies, as well as cost. We hope our data will assist physicians in making decisions with patients.”
Researchers followed 471 patients for up to 10 years. The study is believed to be the largest of early-stage follicular lymphoma (FL) in the modern treatment era. All patients were identified through a disease registry called National LymphoCare, which includes more than 2,700 cases diagnosed between 2004 and 2007, at 200 medical practices in the United States.
As the definition of stage 1 FL changed over time, so did the way doctors evaluated and diagnosed patients. Two groups emerged in the study: People who received a comprehensive staging exam, which included imaging tests and a bone marrow biopsy, and people who were not carefully staged. The latter group had more recurrences and individuals were less likely to survive. This finding emphasizes the importance of a rigorous evaluation at diagnosis as the best way to predict the prognosis, Friedberg said.
Among all patients, researchers observed six treatment approaches, from a conservative watch-and-wait strategy to an aggressive combination of chemotherapy and radiation. An important goal of the Wilmot study was to better understand the outcomes associated with the various treatment options, since no data so far has proven that one therapeutic approach is better than another for early-stage FL. Researchers noted that only 34 percent of patients with stage 1 FL were treated with the recommended radiation therapy, according to their analysis of the national cancer database.
