We found that 32 genes were highly expressed in hypopharyngeal cancer, and the high expression of 16 genes was associated with poor OS, including ACAD9, ERCC5, COL4A5, COQ2, EGFR, EIF2B3, ERCC2, GJA3, JAG1, LDLR, POLG, PROK2, RAD54B, RYR1, SDHA and TUBB3. This evidence concerns the gene ACAD9 and hypopharynx cancer.
