Li W, et al. - In patients with gastric cancer who had undergone radical resection, the physicians retrospectively studied the clinical prognostic consequence of radiomics signature (R-signature). A sum of 181 patients was recruited and a link between R-signature and overall survival (OS) was evaluated and verified in primary and validation cohort. It was examined that radiomics nomogram including R-signature and significant clinicopathological risk factors (T stage, N stage, and differentiation) showed notable prognostic superiority over clinical nomogram and R-signature alone. Therefore, the experts determined that R-signature could be used to scrutinize cases with gastric cancer following radical resection into high- and low-risk groups as radiomics nomogram provided better predictive accuracy than other predictive models.
