In peripheral blood, the ANXA2 serum level has been evaluated in patients with HCC (median, 69.6 ng/ml) [25], early-stage HCC (median, 150 ng/ml) [26], gastric cancer (median, 211.0 ng/ml) [27], lung cancer [28], and oral squamous cell carcinoma (median, 27.1 ng/ml) [29] (Table 2). Here, ANXA2 is linked to lung cancer.
