Summary
Perihilar cholangiocarcinoma frequently recurs after surgery, with a 76% rate observed up to 8 years. Node-positive tumors indicate a poor prognosis, highlighting the need for improved adjuvant therapies and prolonged surveillance.
Area of Science:
- Surgical Oncology
- Gastroenterology
- Hepatobiliary Surgery
Background:
- Perihilar cholangiocarcinoma (PHC) is a challenging upper biliary tract malignancy.
- Curative intent resection is the primary treatment, but recurrence rates are high.
Purpose of the Study:
- To investigate the rate and pattern of tumor recurrence after surgical resection of PHC.
- To identify prognostic factors influencing recurrence-free survival (RFS).
Main Methods:
- Analysis of prospectively maintained databases from 1991-2012.
- Kaplan-Meier method for estimating time to recurrence and RFS.
- Cox proportional hazards modeling for prognostic factor identification.
Main Results:
- A recurrence was diagnosed in 58% of 306 patients.
- Overall recurrence rate reached 76% by 8 years post-resection.
- Independent prognostic factors for RFS included resection margin, lymph node status, and tumor differentiation. Node-positive PHC showed limited RFS beyond 7 years.
Conclusions:
- Most patients (76%) experience recurrence after PHC resection, necessitating improved adjuvant strategies.
- Prolonged surveillance is warranted due to recurrence rates extending up to 8 years.
- Node-positive PHC appears incurable, suggesting limited benefit from current surgical approaches.
