The vertebral 3′-deoxy-3′-18F-fluorothymidine uptake predicts the hematological toxicity after systemic chemotherapy in patients with lung cancer

Objectives Although hematological toxicities (HT) are the leading adverse events of systemic chemotherapy, the estimation of severe HT is challenging. Recently, 3′-deoxy-3′-[18F]-fluorothymidine (18F-FLT) accumulation with PET has been considered a biomarker of the cell proliferation. This study aims to elucidate whether the vertebral accumulation of 18F-FLT could estimate severe HT during platinum-doublet chemotherapy.
