Background/aim: This study aimed to identify the risk factors for early recurrence (ER) after pancreatic ductal adenocarcinoma (PDAC) resection to create a novel scoring system for ER and analyze their effect on the recurrence pattern.
Patients and methods: Sixty patients with PDAC who underwent pancreatectomy were included. The predicted risk factors for ER were analyzed. A new score defining ER was created and analyzed for recurrence pattern and prognosis.
Results: Independent predictors included high CA 19-9 (≥147 U/ml), high lymph node ratio (LNR of ≥0.1277), and no adjuvant chemotherapy (AC). The 5-year overall survival rates with a score of 0, 1, and 2 were 55.8%, 11.0%, and 0%, respectively. In the moderate- risk score group, prognosis was improved by induction of AC within 58 days.
Conclusion: Preoperative high CA19-9, high LNR, and no AC could be ER predictors. Induction of postoperative chemotherapy within 58 days may improve prognosis.
