Fluorine-18 (¹⁸F)-fluoromisonidazole (FMISO) is a positron emission tomography (PET) radiotracer that is widely used to diagnose hypoxia (insufficient oxygen supply to tissue), and non-small cell lung cancer (NSCLC) patients with FMISO uptake are known to face a poor prognosis. A multicenter French Phase II study featured in the July issue of The Journal of Nuclear Medicine (JNM) investigated whether a selective radiotherapy (RT) dose increase to tumor areas with significant FMISO uptake in NSCLC patients could improve outcomes. {read more here}
