The Role of Liquid Biopsy in CCA

On September 2, 2022, the US Food and Drug Administration approved durvalumab in combination with gemcitabine/cisplatin for advanced biliary tract cancers (BTCs) on the basis of the TOPAZ-1 study.

The 2022 ASCO GI Cancers Symposium clearly highlighted the rapid trajectory of clinical research in biliary tract cancers. One of the most eagerly anticipated studies, TOPAZ-1, was presented by Do-Youn Oh, MD, PhD, from Seoul National University Hospital in South Korea. This phase 3 clinical trial enrolled 685 patients and investigated the addition of the PD-L1–directed agent durvalu­mab to gemcitabine and cisplatin chemotherapy backbone versus these chemotherapies alone. The results demonstrated a statistically significant improvement in overall survival (OS), overall response rate (ORR), and progression-free survival (PFS), without dose-limiting toxicities.

The Third CCA Summit was held on October 21-22, 2021 in New Orleans. For the majority of the cholangiocarcinoma (CCA) community, this was their first “live” meeting since the pandemic.
