Abstract


Objectives: We performed a systematic review and meta-analysis on the prognostic values of 18F-FDG PET/CT in patients with newly diagnosed multiple myeloma (MM).

Methods: PubMed and Embase were searched until July 10, 2019, for studies that reported the prognostic significance of 18F-FDG PET in patients with newly diagnosed MM, with overall (OS) and progression-free survival (PFS) included as outcomes. Hazard ratios (HRs) and their 95% confidence intervals (CIs) were meta-analytically pooled using a random-effects model.

Results: Fifteen studies (1670 patients) were included for qualitative synthesis. Among multiple PET parameters, the presence of extramedullary disease (EMD), more than three focal lesions (FLs), and high FDG uptake were widely evaluated and significantly associated with shorter OS and PFS in most of the included studies. Among 11 studies included in quantitative synthesis, the overall HRs of EMD, more than three FLs, and high FDG uptake on PFS were 2.12 (95% CI, 1.52-2.96), 2.38 (95% CI, 1.84-3.07), and 2.02 (95% CI, 1.51-2.68), respectively. The pooled HRs of those three parameters on OS were 2.37 (95% CI, 1.77-3.16), 3.29 (95% CI, 2.38-4.56), and 2.28 (95% CI, 1.67-3.13). No statistical differences were found across parameters for either PFS (p = 0.6822) or OS (p = 0.2147).

Conclusions: Pretreatment 18F-FDG PET/CT is a significant predictor for disease progression and survival in patients with MM. It may be a useful prognostic biomarker capable of accurate risk stratification and application in clinical decision-making for newly diagnosed MM.

Key points: ? There remain unmet clinical needs for reliable prognostic biomarkers in patients with newly diagnosed multiple myeloma. ? This meta-analysis shows that the presence of extramedullary disease, more than three focal lesions, and high FDG uptake from baseline 18F-FDG PET are significant prognostic factors. ? These imaging biomarkers might help the accurate stratification of patient prognosis which is required for choosing an appropriate therapeutic strategy in clinical practice.
