Kaplan-Meier survival curves of disease-free survival (A) and overall survival (B) stratified by the absence of lymphovascular invasion and presence of tumor invasion into non-muscular lymphovascular spaces (LVS) or tumor invasion into muscular vessels in patients with PDAC who received neoadjuvant therapy and pancreaticoduodenectomy. The patients with tumor invasion into muscular vessels had shorter DFS and OS than those patients who were negative for lymphovascular invasion or those who had tumor invasion into non-muscular LVS.
