%X OBJECTIVE: This study aimed to investigate whether clinical outcomes varied based on the tumor location within the pancreatic body and tail in patients with pancreatic cancer (PC).
METHODS: Ninety-five patients who had undergone a distal pancreatectomy for resectable (R) or borderline resectable (BR) PC within the pancreatic body or tail region were retrospectively investigated and divided into four groups (three subgroups of R-PC according to tumor location, and BR-PC): R-PC in the pancreatic body region (group A, n = 24), R-PC on the right side of the pancreatic tail region (group B, n = 17), R-PC on the left side of the pancreatic tail region (group C, n = 29), and BR-PC located in any region within the pancreatic body and tail (group BR, n = 25).
RESULTS: Group C patients showed a higher incidence of pretreatment splenic artery and vein involvement than group A and B patients (splenic artery: 8.3/11.8/41.4%, p < 0.010; splenic vein: 25.0/23.5/79.3%, p < 0.010, in groups A/B/C, respectively). The overall survival of group C patients was significantly unfavorable compared to that of group A and B patients (median: 3.9/4.2/2.3 years in groups A/B/C, p = 0.029, respectively). Pretreatment clinical factors were comparable between group C and group BR. Median survival rates were comparable between group C and BR patients (2.3 and 2.0 years, respectively) (p = 0.93).
CONCLUSIONS: Differences in anatomical location within the pancreatic body and tail characterize the unfavorable outcomes of PC near the splenic hilum.
