Comparison of the prognostic impact of pre- and post-operative CA19-9, SPan-1, and DUPAN-II levels in patients with pancreatic carcinoma

When the prognostic impacts of pre- and post-operative serum CA19-9, SPan-1, and DUPAN-II levels in patients with resectable PDAC were compared, elevated postoperative CA19-9 was the strongest predictive marker of poor survival in the pre- and post-operative period.
