AFP and neoplasm: Further, we performed tumor staging and liver function grading for HCC patients, and compared the level of AFP, LINC00941, and LINC00514 in different stages and grades, and found that AFP levels in advanced HCC patients were significantly higher than those in early and middle‐stage HCC patients, LINC00941 and LINC00514 showed no significant difference in different HCC stages, but showed a trend of gradual decrease with the development of HCC.
