Objectives For NPC patients, distant metastasis is now the main reason for treatment failure. The patients with distinct metastases need different therapeutic regimen and have distinct prognosis. Radiomics might help us predict the type of metastases effectively. Methods The MRI data of seventy non-metastatic NPC patients who develop distant metastasis within five years after treatment were collected and 4410 radiomics features for each patient were extracted by PyRadiomics. Every radiomics feature were compared among patients with distinct metastases and tested by the receiver operating characteristic curve. Results Twenty features have significant differences between the bone metastases cohort and lung metastases cohort, two features have significant differences between the bone metastases cohort and liver metastases cohort, one feature has significant differences between the bone metastases cohort and multiple metastases cohort and sixty-seven features have significant differences between the lung metastases cohort and liver metastases cohort. Six T2WI features could identified lung metastases from bone metastases and liver metastases effectively (AUC = 0.851 ~ 0.896), two T1WI features and one CE T1WI feature could respectively identified bone metastases from liver metastases and multiple metastases effectively (AUC = 0.779 ~ 0.821). Conclusion The results indicate that the radionics features could reflect some of the characteristics of distinct metastases and have potential to be used as predictor of distinct metastases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
