PET Tracer Based FDG Signal for Predicting Prognosis in Acute Myeloid Leukemia

Conditions
Acute Myeloid Leukemia
Interventions
Other: No intervention
Registration Number
NCT05919199
Lead Sponsor
First Affiliated Hospital of Jinan University
Brief Summary

The purpose of this study is to evaluate the predictive value of 18F-FDG PET probe signal in de novo diagnosed or refractory/relapsed patients with acute myeloid leukemia. It is hypothesized that the intensity of 18F-FDG signal, an indicator of glucose uptake capacity, in various cell subsets of bone marrow will improve the predictive effect of clinical standard prognostic work-up.

Detailed Description

Rationale:

FDG is incorporated by leukemia cells and other cell subsets in bone marrow micro-environment of various degree. The heterogeneous FDG uptake is a promising marker for predicting response to treatment. The investigators will collect bone marrow under standard clinical work-up after 18F-FDG PET/CT scan and correlate the FDG signal intensity with clinical and genomics features of the patients to explore its prognostic significance.

Objective:

The primary objective of this research project is to investigate the intensity of FDG PET probe based glucose uptake signal in predicting induction treatment response of AML. As secondary objectives, this analysis will be applied to calculate the overall predictive specificity and sensitivity of FDG probe avidity in predicting PFS and OS.
