Spearman rank correlation analysis further revealed that intratumoral CHKA expression was positively correlated with local invasion (r = 0.148, p = 0.024), lymph node metastasis (r = 0.144, p = 0.028), TNM stage (r = 0.187, p = 0.004), disease recurrence (r = 0.186, p = 0.004), and death (r = 0.239, p < 0.001) (Table S1). This evidence concerns the gene CHKA and metastatic malignant neoplasm in the lymph nodes.
