Ga-68-CXCR4 PET/CT in Indolent B-cell Lymphoma

Phase 2
Recruiting
Conditions
Indolent B-Cell Non-Hodgkin Lymphoma
Interventions
Registration Number
NCT06461182
Lead Sponsor
Koo Foundation Sun Yat-Sen Cancer Center
Brief Summary

This study explores the efficacy of Ga-68-PentixaFor PET/CT in detecting, assessing treatment response, and monitoring the risk of aggressiveness in indolent B-cell lymphoma. The background introduces CXCR4 and discusses its role in cancer research. Currently, FDG-PET is the primary imaging tool for lymphoma staging, but it lacks diagnostic accuracy for low-grade lymphomas. Ga-68-PentixaFor PET demonstrates promising detection capabilities across various lymphomas, suggesting its potential as a superior imaging modality for low-grade lymphomas.

Primary Outcome Measures
NameTimeMethod
Performance of Ga-68-CXCR4 PET/CT in indolent B cell lymphomaup to 24 months

Detection rate = number of positive scan / total number of scan Sensitivity = number of true positive scan / total number of proven recurrent patient Specificity = number of true negative scan / total number of proven free of disease patient Accuracy = number of (true positive scan + true negative scan) / total number of scan Positive predictive value = number of true positive scan / number of positive scan Negative predictive value = number of true negative scan / number of negative scan

Secondary Outcome Measures
NameTimeMethod
Ga-68-CXCR4 compared to F-18-FDG PET/CTup to 24 months

McNemar test, Two-tailed,P\<.05

Prognostic value of Ga-68-CXCR4 PET/CT scanup to 36 months

The correlation between the radiomic features of Ga-68-CXCR4 PET/CT scan and progression free survival.

CXCR4 radiomics : Feature extraction was performed with the open-source Python package pyradiomics. For each volume of interest (VOI), including first-order statistics, shape features, grey level co-occurrence matrix (GLCM), grey level run length matrix (GLRLM), grey level size-zone matrix (GLSZM), neighborhood grey level different matrix (NGLDM), and grey level dependence matrix (GLDM).

Clinical impact of Ga-68-CXCR4 compared to F-18-FDG PET/CTup to 24 months

Treatment plan questionnaires before and after Ga-68-CXCR4 PET/CT
