Does minimally invasive surgery have a different impact on recurrence and overall survival in patients with pancreatic head versus body/tail cancer?

Abstract

AbstractObjectiveThis study sought to investigate the impact of minimally invasive surgery (MIS) on recurrence and overall survival between patients with pancreatic head versus body/tail cancers.MethodsThe risk factors associated with recurrence and long‐term outcomes were analyzed according to tumor location and operative modality.ResultsA total of 288 and 87 patients underwent surgical resection for pancreatic head cancer and body/tail cancer, respectively. The perioperative outcomes and histopathologic results were comparable in open and MIS approach in both head and body/tail groups. There was no difference in local or systemic recurrence patterns and disease‐free and overall survival rates according to primary tumor location and surgical modality. During subgroup analysis by stage; however, patients with stage III pancreatic head cancer in the MIS group had a decreased disease‐free survival compared with those in the open surgery group (p = 0.020). On multivariate analysis, MIS was not a risk factor of total or local recurrences.ConclusionsRecurrence patterns and overall survival rates of patients did not differ according to tumor location and surgical approach. However, patients with stage III pancreatic head cancer in the MIS group showed inferior disease‐free survival relative to patients who underwent open surgery.
