However, when the prognostic value of CYP1B1 was analyzed using univariate Cox regression, the overall survival rate was significantly affected by CYP1B1 expression (p = 0.039; HR = 1.335, 95% CI = 1.014–1.758), along with other parameters such as age, lymph node metastasis, distant metastasis, grade, and stage, implying poor survival (Table 2). Here, CYP1B1 is linked to metastatic malignant neoplasm in the lymph nodes.
