For I-type tumors, a significant inverse association was found between RBM3 expression and tumor size (p = 0.030), and in PB-type tumors, RBM3 expression was significantly associated with the presence of lymph node metastases (p = 0.015), larger tumor size (p = 0.031), and with growth in peripancreatic fat (p = 0.027). The gene discussed is RBM3; the disease is neoplasm.
