SOX21 and neoplasm: We observed differences in the case of age (for SOX30: p = 0.0395), alcohol consumption (for SOX30: p = 0.0093; for SRY: p = 0.0102), pathological stage (for SOX21; p = 0.0064), pathological T-stage (for SOX21; p = 0.0005) and pathological N-stage (for SOX21; p = 0.0114 and for SOX30: p = 0.0114) and no differences in the expression levels of all SRY-related transcription factors for gender, tumor grade, clinical stage and clinical cervical lymph nodes status (p > 0.05).
