Summary
Mesopancreatic fat infiltration is common in distal pancreatic cancer, but does not affect margin status. However, clear margins improve survival and reduce recurrence in these patients.
Area of Science:
- Oncology
- Surgical Pathology
- Gastroenterology
Background:
- The pathologic circumferential resection margin (CRM) staging system increased R1 resections for pancreatic head cancer (hPDAC), linked to mesopancreatic fat (MP) infiltration.
- Mesopancreatic excision (MPE) improves local control in hPDAC, prompting neoadjuvant therapy discussions for MP-positive cases.
- The extent of MP infiltration and its impact on surgical margins in distal pancreatic cancer (dPDAC) remain unclear.
Purpose of the Study:
- To histopathologically analyze MP infiltration in dPDAC.
- To determine the influence of MP infiltration on surgical margin clearance in dPDAC.
- To compare MP infiltration and outcomes in dPDAC with hPDAC patients undergoing MPE.
Main Methods:
- Clinicopathological and survival data from 295 pancreatic ductal adenocarcinoma (PDAC) patients (63 dPDAC, 232 hPDAC) were analyzed.
- Standardized CRM evaluation using the Leeds pathology protocol (LEEPP).
- Histopathological examination of the MP area for cancerous infiltration.
Main Results:
- MP fat infiltration occurred in 75.4% of dPDAC patients.
- MP infiltration and R0CRM- resection rates were similar between dPDAC and hPDAC groups.
- MP status did not correlate with CRM resection status in dPDAC; however, R0CRM- resection significantly reduced local recurrence (5.2% vs. 33.3%, p=0.002).
Conclusions:
- High MP infiltration rates in dPDAC, similar to hPDAC, support considering MPE during splenopancreatectomy.
- While MP status doesn't impact margin status in dPDAC, achieving R0CRM- resection is crucial for improved survival and reduced local recurrence.
- Further large-scale studies are needed to validate these findings and explore neoadjuvant treatment effects in dPDAC.
