Eigentumors for prediction of treatment failure in patients with early-stage breast cancer using dynamic contrast-enhanced MRI: a feasibility study

Abstract: We present a radiomics model to discriminate between patients at low risk and those at high risk of treatment failure at long-term follow-up based on eigentumors: principal components computed from volumes encompassing tumors in washin and washout images of pre-treatment dynamic contrast-enhanced (DCE-) MR images. Eigentumors were computed from the images of 563 patients from the MARGINS study. Subsequently, a least absolute shrinkage selection operator (LASSO) selected candidates from the components that cont… Show more

“…While Hattangadi et al [ 12 ] focused on tumour-induced changes to the parenchyma directly around the index tumour, CPE focuses on the properties of the healthy parenchyma prior to tumourigenesis. Texture analysis of parenchymal tissue has been associated with signalling pathways and patient survival [ 37 , 38 ].…”

“…Dynamic contrast‐enhanced (DCE)‐MRI is essential in breast MRI applications, as it provides anatomical and hemodynamic information regarding the tumor with a high spatial resolution. DCE‐MRI‐based radiomics have been used for differentiating malignancy, classifying molecular subtypes, assessing Ki67 status, evaluating the risk of recurrence, predicting the response to treatment, and predicting sentinel lymph node metastasis in breast cancer . However, DCE‐MRI‐based radiomics for LVI prediction remains underinvestigated.…”

“…Accumulating evidence also suggests the predictive value of an MRI-based radiomics model in nasopharyngeal carcinoma, breast cancer, glioma and cervical cancer. [29][30][31][32][33][34] Given the widespread application and predictive value of MRI, it is necessary to build an MRI-based prognosis model for treatment guidance in resectable HCC.…”
