HSPA2 and pancreatic neoplasm: The median HSPA2 mRNA expression level of pancreatic cancer tissues (4.1) was used as a cut-off point to divide all 104 patients into two groups: pancreatic cancer patients who expressed HSPA2 at levels less than the cut-off value were assigned to the low expression group (n = 49), and those with HSPA2 mRNA expression higher than the cut-off value were assigned to the high expression group (n = 55).
