Résumé
Most patients with localized cholangiocarcinoma (CCA) endure cancer relapse after curative resection underscoring the importance of systemic therapy. The current study attempts to determine the impact of perioperative chemotherapy (PC) on survival in patients with CCA undergoing resection. Patients diagnosed with CCA undergoing curative-intent resection between January 1, 2000, and December 31, 2019, in a tertiary care center were included. Cox proportional hazard modeling was used to determine the impact of PC on disease-free survival (DFS) and overall survival (OS). In addition, a nomogram was constructed to estimate 3-year DFS. Among the 182 patients included in the analysis, 102 underwent surgery alone, and 80 received surgery plus PC. Forty-two patients received neoadjuvant therapy, and 38 patients received adjuvant therapy. On multivariate analysis, PC was significantly associated with an improved DFS (HR, 95% CI: 0.63, 0.41-0.98; p = 0.04) and OS (HR, 95% CI: 0.46, 0.27-0.78; p < 0.01). In the interaction analysis, the survival benefit was especially seen in patients with positive resection margins and tumor size > 5 cm. In patients with CCA undergoing curative resection, receipt of PC was associated with improved DFS and OS. The nomogram constructed from this database provides an estimate of 3-year DFS after surgical resection. Randomized trials are needed to define the optimal regimen and sequence.

BACKGROUND
BACKGROUND
Most patients with localized cholangiocarcinoma (CCA) endure cancer relapse after curative resection underscoring the importance of systemic therapy. The current study attempts to determine the impact of perioperative chemotherapy (PC) on survival in patients with CCA undergoing resection.
METHODS
METHODS
Patients diagnosed with CCA undergoing curative-intent resection between January 1, 2000, and December 31, 2019, in a tertiary care center were included. Cox proportional hazard modeling was used to determine the impact of PC on disease-free survival (DFS) and overall survival (OS). In addition, a nomogram was constructed to estimate 3-year DFS.
RESULTS
RESULTS
Among the 182 patients included in the analysis, 102 underwent surgery alone, and 80 received surgery plus PC. Forty-two patients received neoadjuvant therapy, and 38 patients received adjuvant therapy. On multivariate analysis, PC was significantly associated with an improved DFS (HR, 95% CI: 0.63, 0.41-0.98; p = 0.04) and OS (HR, 95% CI: 0.46, 0.27-0.78; p < 0.01). In the interaction analysis, the survival benefit was especially seen in patients with positive resection margins and tumor size > 5 cm.
CONCLUSION
CONCLUSIONS
In patients with CCA undergoing curative resection, receipt of PC was associated with improved DFS and OS. The nomogram constructed from this database provides an estimate of 3-year DFS after surgical resection. Randomized trials are needed to define the optimal regimen and sequence.
