OLFM4 and adenocarcinoma: Notably, there were no significant relationships between high and low OLFM4 expression groups, including age (p = 0.46), sex (p = 0.061), tumor location (head or body/tail, p = 0.37), histological type (adenocarcinoma or others, p = 0.52), TNM stage (IIA or IIB, p = 1.00), lymphatic invasion (p = 0.68), venous invasion (p = 0.11), and presence of adjuvant chemotherapy (p = 0.94).
