The eGFR10 model was trained on 75 patients and tested on 27, while the eGFR20 model was trained on 77 patients and tested on 24. The vViT model inputs included class token, patient characteristics (age, sex, BMI), comorbidities (peripheral vascular disease, diabetes, liver disease), habits (smoking, alcohol), surgical details (ischemia time, blood loss, type and procedure of surgery, approach, operative time), radiomics, and tumor and kidney imaging. We used permutation feature importance to evaluate each sector's contribution. The performance of vViT was compared with CNN models, including VGG16, ResNet50, and DenseNet121, using McNemar and DeLong tests.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>The eGFR10 model achieved an accuracy of 0.741 and an AUC-ROC of 0.692, while the eGFR20 model attained an accuracy of 0.792 and an AUC-ROC of 0.812. The surgical and radiomics sectors were the most influential in both models. The vViT had higher accuracy and AUC-ROC than VGG16 and ResNet50, and higher AUC-ROC than DenseNet121 (p\u2009&lt;\u20090.05). Specifically, the vViT did not have a statistically different AUC-ROC compared to VGG16 (p\u2009=\u20091.0) and ResNet50 (p\u2009=\u20090.7) but had a statistically different AUC-ROC compared to DenseNet121 (p\u2009=\u20090.87) for the eGFR10 model. For the eGFR20 model, the vViT did not have a statistically different AUC-ROC compared to VGG16 (p\u2009=\u20090.72), ResNet50 (p\u2009=\u20090.88), and DenseNet121 (p\u2009=\u20090.64).<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusion<\/jats:title>\n                <jats:p>The vViT model, a transformer-based approach for multimodal data, shows promise for preoperative CT-based prediction of eGFR status in patients with renal cell carcinoma.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1007\/s10278-024-01180-0","type":"journal-article","created":{"date-parts":[[2024,6,28]],"date-time":"2024-06-28T17:00:03Z","timestamp":1719594003000},"page":"3057-3069","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Predicting EGFR Status After Radical Nephrectomy or Partial Nephrectomy for Renal Cell Carcinoma on CT Using a Self-attention-based Model: Variable Vision Transformer (vViT)"],"prefix":"10.1007","volume":"37","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3945-3432","authenticated-orcid":false,"given":"Takuma","family":"Usuzaki","sequence":"first","affiliation":[]},{"given":"Ryusei","family":"Inamori","sequence":"additional","affiliation":[]},{"given":"Mami","family":"Ishikuro","sequence":"additional","affiliation":[]},{"given":"Taku","family":"Obara","sequence":"additional","affiliation":[]},{"given":"Eichi","family":"Takaya","sequence":"additional","affiliation":[]},{"given":"Noriyasu","family":"Homma","sequence":"additional","affiliation":[]},{"given":"Kei","family":"Takase","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2024,6,28]]},"reference":[{"key":"1180_CR1","doi-asserted-by":"publisher","unstructured":"Chandrasekar T, Boorjian SA, Capitanio U, Gershman B, Mir MC, Kutikov A.
