Other studies, such as those by Hsu et al., Chen et al., Jiang et al., Zhou et al., and Li et al. (2022) [23,25,33,34], also explored prognostic factors for EWS across different sample sizes and tumor locations, confirming the importance of factors such as age, race, tumor stage, surgery, chemotherapy, and metastasis. This evidence concerns the gene EWSR1 and neoplasm.
