BACKGROUND: Despite advances in the treatment of oncology patients, therapy-related side effects may lead to premature morbidity. Inflammatory activation that has been linked to cardiovascular disease is crucial for the pathogenesis of both Hodgkin (HL) and non-Hodgkin lymphoma (NHL).
OBJECTIVES: The purpose of this study was to assess the vascular effects of chemotherapy in patients with HL and NHL by positron emission tomography/computed tomography with 18-fluorodeoxyglucose (18-FDG PET/CT) and to investigate interactions with systemic inflammation as assessed by circulating inflammatory markers.
METHODS: Between July 2015 and July 2019, 65 consecutive patients (mean age 56 ± 17.78 years) with confirmed diagnosis of either HL (n = 33) or NHL (n = 32) were prospectively studied. PET/CT imaging was performed at baseline, at an interim phase, and after first-line treatment. Aortic FDG uptake was assessed by measuring global aortic target-to-background ratio (GLA-TBR). Serum biomarkers interleukin (IL)-6 and IL-1b were measured at each phase.
RESULTS: Patients with HL demonstrated significant reduction in aortic TBR after first-line treatment (median GLA-TBR baseline: 1.98, median GLA-TBR third scan: 1.75, median difference = -0.20, 95% CI: -0.07 to -0.33, P = 0.006), which remained significant after adjustment for confounders (adj. R2 of model = 0.53). In contrast, patients with NHL did not demonstrate a significant aortic inflammation response (P = 0.306). Furthermore, patients with HL demonstrated a significant reduction in IL-6 (P = 0.048) and IL-1b (P = 0.045), whereas patients with NHL did not demonstrate significant reduction in IL-6 (P = 0.085) and IL-1b levels (P = 0.476).
CONCLUSIONS: Aortic inflammation, as assessed by 18-FDG PET/CT, is reduced in HL patients after first-line treatment but not in NHL patients. These findings imply that different pathophysiological pathways and different therapies might affect the arterial bed in different ways for patients with lymphoma.
