Evaluating 18F-FDG PET/CT With Liver SUVmax-based Criteria for Prognosis of Patients With Peripheral T-cell Lymphoma

NCT ID: NCT03051568

Last Updated: 2017-02-13

Basic Information

• Recruitment Status: UNKNOWN
• Clinical Phase: NA
• Total Enrollment: 80 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2017-03-01
• Study Completion Date: 2020-12-31

Brief Summary

The purpose of this study is to evaluate whether a semi-quantitative interpretation using the liver SUVmax as reference can better interpret 18F-FDG PET/CT and predict disease progression during chemotherapy or survival in PTCL.

Detailed Description

In this study investigators develope a semi-quantitative interpretation using the liver SUVmax as reference to interpret 18F-FDG PET/CT. Positive lesions in PET were indicated as SUVmax of residues higher than the threshold or new 18F-FDG avid lesions. Investigators compare the prognostic accuracy of the liver SUVmax-based criteria with the 5-PS criteria and ΔSUVmax interpretation with respect to predicting disease progression during chemotherapy or survival in PTCL. Furthermore,investigators improve the prognostic ability of interim PET/CT by comparing the results to the clinical prognostic factors.

Conditions

Lymphoma, T-Cell, Peripheral

Study Design

• Allocation Method: NA
• Intervention Model: SINGLE_GROUP
• Primary Study Purpose: DIAGNOSTIC
• Blinding Strategy: NONE

Study Groups

PTCL patients with 18F-FDG PET/CT

18F-FDG PET/CT scans is to be evaluated using liver SUVmax-based criteria, Deauville 5-point criteria and reduction of SUVmax criteria

Group Type: EXPERIMENTAL

18F-FDG PET/CT

Intervention Type: DEVICE

18F-FDG PET/CT will be conducted before, during and after chemotherapy. Patients were instructed to fast for at least 6 h before PET. The blood glucose level was measured to ensure that it was \<200 mg/dL. 18F-FDG was intravenously administered at a dose of 3.7 MBq/kg. Approximately 60 ± 10 min post injection, a whole-body acquisition commenced in 6-8 bed positions (1 min/bed) using a hybrid system (PHILIPS Gemini TF) and covered from the base of the skull to the upper thigh, which was followed by CT in a non-contrast phase (modulated 100 mAs; 120 kV; slice thickness, 3 mm) for attenuation correction and anatomical localization purposes. The head acquisition was performed in one bed position (8-10 min/bed).
