Curative-intent surgery for hilar cholangiocarcinoma: prognostic factors for clinical decision making.
BACKGROUND
The surgical approach for hilar cholangiocarcinoma (HC) has largely evolved, and increased resectability rates are reported. Large series of patients with resections for HC were published in the last years, and potential predictors for survival were explored. However, the usefulness of these predictors in clinical decision making is controversial.


OBJECTIVE
The aim of the present review is to explore the main prognostic factors after curative-intent surgery for HC, as emerged from the current literature. Furthermore, the impact of these predictors on clinical decision making is assessed.


CONCLUSIONS
An aggressive surgical approach has improved the survival rates in patients with HC and implies bile duct resection associated with liver resection and loco-regional lymph node dissection. The AJCC staging system remains the main tool to assess the prognosis after resection of HC. Margin-negative resections and absence of lymph node metastases are the main prognostic factor after curative-intent surgery for HC. Response to chemotherapy is also a prognostic factor. Markers of systemic inflammatory response might predict prognosis of patients with HC, but their usefulness in clinical decision making remains unclear.
