Summary
Achieving a complete microscopic tumor clearance (R0 resection >1 mm) after distal bile duct cancer surgery significantly improves patient survival. This study validates the R0 resection definition for distal bile duct cancer outcomes.
Area of Science:
- Surgical Oncology
- Gastroenterology
- Pathology
Background:
- Distal bile duct cancer (DBC) is rare, with oncologic resection offering the sole curative potential.
- Evaluating resection margins is crucial for predicting outcomes in DBC surgery.
Purpose of the Study:
- To assess outcomes following distal bile duct cancer resection.
- To determine the impact of microscopic histopathological resection status (R0 >1 mm vs. R1 ≤1 mm vs. R1 direct) on survival.
Main Methods:
- Analysis of prospectively collected data from patients undergoing pancreaticoduodenectomy for DBC.
- Classification of histopathological resection status using the Leeds protocol for pancreatic ductal adenocarcinoma (PDAC).
Main Results:
- 196 patients underwent pancreaticoduodenectomy for DBC; 58% achieved R0 resection (>1 mm).
- Median overall survival (OS) was 37 months; R0 resection improved median OS to 78 months (5-year OS: 52%).
- Negative prognostic factors included age >70, blood loss >1000 mL, pN1/pN2 status, and ASA score >II.
Conclusions:
- The revised PDAC resection status definition is applicable to DBC.
- "True" R0 resection (>1 mm) is critical for superior survival in DBC patients.
- Unlike PDAC, R1 (≤1 mm) and R1 (direct) margins showed no significant survival difference in DBC.
