Cyclin D1 expression in combination with lymph node status is associated with disease recurrence. A: Disease-free survival of patients with lymph node metastasis (LN+) is compared to that of patients without lymph node metastasis (LN−). B: Disease-free survival of four subgroups of patients. Patients were stratified into four different groups based on the level of cyclin D1 expression and lymph node metastasis: Patients with high cyclin D1 expression but no lymph node metastasis; patients with low cyclin D1 expression and no lymph node metastasis; patients with low cyclin D1 but with lymph node metastasis; patients with high cyclin D1 expression and lymph node metastasis. Log-rank test was performed.
