RAD50 and neoplasm: In the AHNTU cohort, increased RAD50 expression was significantly associated with larger tumour size (p < 0.001), advanced AJCC stage (p = 0.003), the presence of multiple primary tumour lesions (p = 0.010), the degree of pathological nuclear differential expression (p = 0.005), the presence of microvascular invasion (p = 0.001), the presence of capsular invasion (p = 0.003), and higher Okuda score (p = 0.008).
