Pancreatectomy with Vascular Resection After Neoadjuvant FOLFIRINOX: Who Survives More Than a Year After Surgery?

Résumé

Background: Experienced pancreatic surgeons, for whom complexity is not an issue, must decide at the end of neoadjuvant therapy whether to continue or discontinue surgery, when pancreatectomy with vascular resection is planned in patients with pancreatic ductal adenocarcinoma (PDAC). Objective: Our study aimed to determine preoperative factors that can predict short postoperative survival in such situations. Methods: Overall, 105 patients with borderline or locally advanced PDAC received neoadjuvant FOLFIRINOX (followed by chemoradiation in 22% of patients) and underwent pancreatectomy with segmental venous and/or arterial resection at two high-volume centers. The primary endpoint was overall survival (OS) of < 1 year after surgery for patients who did not die from the surgery. Results: Tumors were classified as borderline in 78% of cases and locally advanced in 22% of cases. Mean CA19-9 at diagnosis was 934 U/mL, which significantly decreased to 213 U/mL (p < 0.01) after a median of six cycles of FOLFIRINOX. Pancreaticoduodenectomy was performed most often (76%). The vast majority of patients underwent venous resection (92%), and a simultaneous arterial resection was performed in 16 patients (15%). The severe morbidity rate and 30- and 90-day mortality rates were 21%, 8.5%, and 10.4%, respectively. The median OS after surgery was 23 months. In the multivariate analysis, preoperative CA19-9 ≥ 450 U/mL was the only preoperative factor independently associated with OS of < 1 year (p = 0.044). Conclusion: The preoperative CA19-9 value should be considered in the clinical decision-making process when complex vascular resection is required. © 2021, Society of Surgical Oncology.
