Objective:
Neoadjuvant therapy (NAT) has become part of the multimodality treatment for borderline resectable pancreatic cancer (BRPC) and locally advanced pancreatic cancer (LAPC).
Summary Background Data:
It is currently uncertain which are the preferable NAT regimens, who benefits from surgery, and whether more aggressive surgical strategy is motivated.
Methods:
A retrospective cohort analysis was performed for all patients with BRPC/LAPC discussed and planned for NAT at multidisciplinary conference at Karolinska University Hospital from 2010 to 2017.
Results:
Of 233 patients eligible, 168 (72%) received NAT and were reevaluated for possibility of resection. A total of 156 (67%) patients (mean 64 yrs, 53% male) had pancreatic adenocarcinoma, comprising the study group for survival analysis. LAPC was diagnosed in 132 patients (85%), BRPC in 22 (14%), and resectable tumor in 2 (1.3%). Fifty patients (40.3%) received full-dose NAT. Only 54 (34.6%) had FOLFIRINOX. The overall survival among resected patients was similar for BRPC and LAPC (median survival 15.0 vs 14.5 mo, P = 0.4; and 31.9 vs 21.8 mo, P = 0.7, respectively). Resected patients had better survival than nonresected, irrespective of the type or whether full-dose NAT was given (median survival 22.4 vs 12.7 mo; 1-, 3-, and 5-yr survival: 86.4%, 38.9%, 26.9% vs 52.2%, 1.5%, 0%, respectively (P < 0001). For all preoperative values of Ca 19-9, surgical resection had positive impact on survival.
Conclusions:
All patients with BRPC/LAPC who do not progress during NAT should be considered for surgical resection, irrespective of the type or dose of NAT given. Higher levels of Ca 19-9 should not be considered an absolute contraindication for resection.
The findings show DP-CAR to be a valid procedure for treating locally advanced pancreatic body cancer, which might contribute more to patients' survival when performed as part of multidisciplinary treatment.
This study demonstrated that preoperative bile culture-targeted administration of prophylactic antibiotics decreased SSIs following HBP surgery with biliary reconstruction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
