Clinical studies of 210 RCC patients from The Cancer Imaging Archive (TCIA) who underwent either partial or radical nephrectomy were included in this study. Regions of interest (ROIs) were manually defined on CT images. A total of 225 radiomic features were extracted and analyzed along with the 59 clinical features. An elastic net penalized Cox regression was used for feature selection. Accelerated failure time (AFT) with the shared frailty model was used to determine the effects of the selected features on the overall survival time. Eleven radiomic and twelve clinical features were selected based on their non-zero coefficients. Tumor grade, tumor malignancy, and pathology t-stage were the most significant predictors of overall survival (OS) among the clinical features (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.002,\u2009&lt;\u20090.02, and\u2009&lt;\u20090.018, respectively).

Along with important clinical features, such as tumor heterogeneity and tumor grade, imaging biomarkers such as tumor flatness, area density, and median are significantly correlated with OS of RCC patients.<\/jats:p>","DOI":"10.1007\/s10278-021-00500-y","type":"journal-article","created":{"date-parts":[[2021,8,11]],"date-time":"2021-08-11T22:02:24Z","timestamp":1628719344000},"page":"1086-1098","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":67,"title":["Overall Survival Prediction in Renal Cell Carcinoma Patients Using Computed Tomography Radiomic and Clinical Information"],"prefix":"10.1007","volume":"34","author":[{"given":"Zahra","family":"Khodabakhshi","sequence":"first","affiliation":[]},{"given":"Mehdi","family":"Amini","sequence":"additional","affiliation":[]},{"given":"Shayan","family":"Mostafaei","sequence":"additional","affiliation":[]},{"given":"Atlas","family":"Haddadi Avval","sequence":"additional","affiliation":[]},{"given":"Mostafa","family":"Nazari","sequence":"additional","affiliation":[]},{"given":"Mehrdad","family":"Oveisi","sequence":"additional","affiliation":[]},{"given":"Isaac","family":"Shiri","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7559-5297","authenticated-orcid":false,"given":"Habib","family":"Zaidi","sequence":"additional","affiliation":[]}],"member":"297","published-online":{"date-parts":[[2021,8,11]]},"reference":[{"key":"500_CR1","doi-asserted-by":"publisher","first-page":"3591","DOI":"10.1200\/JCO.2018.79.2341","volume":"36","author":"A Sanchez","year":"2018","unstructured":"Sanchez A, Feldman AS, Hakimi AA: Current management of small renal masses, including patient selection, renal tumor biopsy, active surveillance, and thermal ablation.
