Prognostic analysis showed that SOX9 expression was positively correlated with the prognosis of ACC patients and negatively correlated with the prognosis of LGG, CESC, and THYM patients, which suggests that SOX9 is likely to be an oncogene, making it an important factor affecting the prognosis of LGG, CESC, and THYM patients. Here, SOX9 is linked to cervical squamous cell carcinoma.
