Official title
PET/MR in the Staging and Efficacy Evaluation of Newly Diagnosed NK/T-cell Lymphoma: a Prospective, Single-arm Clinical Study
Overview
This study intends to evaluate the application value of Positron Emission Tomography/Magnetic Resonance (PET/MR) in the staging and efficacy evaluation of NK/T cell lymphoma, aiming to explore a more accurate system for predicting the prognosis of patients and guiding the treatment.
Detailed description
Nature Killer/T-cell Lymphoma (NKTCL) is a highly heterogeneous, aggressive lymphoma subtype with poor prognosis. Ninty percent of patients have lesions involving the nasal region, other extranodal organs include adrenal glands, gastrointestinal tract, skin and so on. Local tumor infiltration (bone, skin, paranasal sinus, etc) is a poor prognostic factor. Therefore, NK/T-cell lymphomas have high demands on the resolution of fine anatomical structures. PET/CT and nasopharyngeal contrast-enhanced MR are routine examination methods for diagnostic staging and efficacy evaluation, but the images cannot be fused, and the divided examinations bring inconvenience to patients.
Interventions
- Device Positron Emission Tomography/Magnetic Resonance (PET/MR)
18F-FDG PET/MR imaging (manufacturer: Siemens, model: Biography mMR). Research devices are marketed products.
Primary outcome measures
- The sensitivity, specificity and accuracy of PET/MR in the staging of newly diagnosed NK/T-cell lymphoma patients [Time frame: Baseline]
- The sensitivity, specificity and accuracy of PET/MR in the efficacy evaluation of newly diagnosed NK/T-cell lymphoma patients [Time frame: After at least 2 cycles]
Secondary outcome measures (1)
- Exploratory construction of prognostic prediction or efficacy evaluation system for newly treated NK/T-cell lymphoma based on PET/MR imaging indicators. [Time frame: Baseline up to data cut-off (up to approximately 4 years)]
Eligibility criteria
Inclusion criteria
