BACKGROUND: The malignancy of cholangiocarcinoma is highly pronounced, and it exhibits a propensity for recurrence and metastasis even in the presence of standard chemotherapy. The efficacy of adjuvant chemotherapy combined with immunotherapy in patients with resected cholangiocarcinoma needs to be substantiated.
METHODS: Data from 101 patients with cholangiocarcinoma treated at the Sun Yat-sen University Cancer Center between 2015 and 2020 were studied.
RESULTS: After propensity score matching, there were no significant differences in baseline characteristics between patients in the combined adjuvant chemotherapy and immunotherapy group (AC + IM group) and the adjuvant chemotherapy alone group (AC group) (all p > 0.05). The AC + IM group demonstrated a statistically significant improvement in relapse-free survival (RFS) compared to the AC group (p = 0.032). Likewise, the AC + IM group exhibited a significantly superior overall survival (OS) outcome when compared to the AC group (p = 0.044). Multivariate Cox analysis unveiled perineural invasion (p = 0.041), lymph node metastasis (p = 0.006), and postoperative immunotherapy (p = 0.008) as independent prognostic factors exerting a significant impact on the OS of patients. In the cohort of patients with perineural invasion, the AC + IM group exhibited significantly improved OS compared to the AC group (p = 0.0077). Similarly, within the subset of patients with lymph node metastasis, the AC + IM group exhibited a significantly superior OS outcome when compared to the AC group (p = 0.023).
CONCLUSION: Combining postoperative adjuvant chemotherapy with immunotherapy extends the RFS and OS of patients with cholangiocarcinoma following radical resection.
