Furthermore, patients with HL demonstrated a significant reduction in IL-6 (<i>P</i> = 0.048) and IL-1b (<i>P</i> = 0.045), whereas patients with NHL did not demonstrate significant reduction in IL-6 (<i>P</i> = 0.085) and IL-1b levels (<i>P</i> = 0.476).<h4>Conclusions</h4>Aortic inflammation, as assessed by 18-FDG PET/CT, is reduced in HL patients after first-line treatment but not in NHL patients. The gene discussed is IL6; the disease is Hodgkins lymphoma.
