Tyler Seibert: 10-year Results of FLAME Trial is Out Now

Tyler Seibert, Assistant Professor in the Division of Radiation Oncology and a member of the RMAS Center for Precision Radiation Medicine (CPRM), shared a post on X:

“10-year results of FLAME out in Journal of Clinical Oncology

  •  bDFS (15%), local recurrence
  •  nodal metastasis

No diff in toxicity—this is a freebie!

DMFS 87% vs 83% (p=0.12).

bDFS

0.40 [95% CI, 0.26 to 0.61]; P < .001

At 90 Gy, recurrence very low.

Tyler Seibert

Regional nodal DFS lower with focal boost. No pelvic nodal RT in this trial 85% (95% CI, 80% to 90%).

Tyler Seibert

Local recurrences very low with high boost dose.

Tyler Seibert

DMFS HR, 0.69 [95% CI, 0.43 to 1.10]; P = .12

Though dose response suggestive. Remember only ~50% of pts in boost arm got a substantial boost.”
