Gitto, Pantel et al. evaluate a PARP-targeted PET imaging ligand, [18 F]FlourThanatrace, as a biomarker of response to PARP inhibitors in patients with breast cancer. There is [18 F]FlourThanatrace uptake in the tumor before treatment, and a decline in uptake after PARP inhibitor therapy initiation, correlating with patient progression free survival.
