PET interim results could promptly select Follicular Lymphoma patients in need of maintenance therapy. Potential additional value of ctDNA.

PET interim results could promptly select Follicular Lymphoma patients in need of maintenance therapy. PET/CT SB EOT sb were predictive of relapse, with 2-years PFS 47% in PET/CT SB EOT sb (+) vs. 89% in PET/CT SB EOT sb (-) ( I p i <.001).On iPET/CT, 41 (34%) patients were PET/CT(+).The estimated 5 year-PFS at was 72% in patients with a negative iPET/CT versus 29% in those with a positive iPET/CT ( I p i < 0.001) (Figure 1a). B Conclusion: b Response assessment by PET/CT at mid-induction can identify FL patients at high risk of failure early on during first line ICT and is able promptly select patients in whom maintenance therapy could be avoided.
