Further studies found that high CRYAB and p53 co-expression was also significantly correlated with pathological grade (P=0.024), lymph node metastasis (P=0.000), Distant metastasis (P=0.015), TNM stage (P=0.013), and survival (P=0.000). The gene discussed is TP53; the disease is metastatic malignant neoplasm in the lymph nodes.
