Analyses of the contributions of BAMBI to overall survival, disease-free survival, tumor grade, and nodal metastasis in the 11 types of cancers showed that higher BAMBI expression was associated with poor prognosis and greater nodal metastasis in HCC, suggesting that BAMBI can serve as a diagnostic biomarker and an indicator of unfavorable prognosis in HCC. This evidence concerns the gene BAMBI and neoplasm.
