Summary
More than half of patients with distal cholangiocarcinoma (DCC) recur after surgery. Key risk factors for recurrence include perineural invasion, pancreatic invasion, and lymph node metastasis, impacting recurrence-free survival (RFS).
Area of Science:
- Oncology
- Surgical Gastroenterology
- Hepatobiliary Surgery
Background:
- Distal cholangiocarcinoma (DCC) recurrence patterns post-resection are understudied.
- Understanding recurrence is crucial for improving patient outcomes after surgery.
Purpose of the Study:
- To investigate the incidence and patterns of recurrence following distal cholangiocarcinoma resection.
- To identify prognostic factors influencing time to recurrence and recurrence-free survival (RFS).
Main Methods:
- Retrospective review of 389 patients undergoing pancreatoduodenectomy for DCC with curative intent (2001-2010).
- Analysis focused on recurrence patterns and utilized Cox proportional hazards model for multivariable analysis.
Main Results:
- 54.8% of patients experienced recurrence, with 54.3% cumulative probability at 5 years.
- Initial distant recurrence (43.2%) was more common than locoregional recurrence (14.1%), often to the liver.
- Perineural invasion, pancreatic invasion, and lymph node metastasis were independent predictors of earlier recurrence and reduced RFS.
Conclusions:
- Over half of distal cholangiocarcinoma patients recur after R0 resection, typically within five years.
- Perineural invasion, pancreatic invasion, and lymph node metastasis are significant risk factors for recurrence.
- Increased risk factors correlate with significantly worse recurrence-free survival rates.
