Abstract

Introduction: The TOPAZ-1 phase III trial showed a survival benefit with durvalumab plus gemcitabine and cisplatin in patients with advanced biliary tract cancer (BTC). To understand this combination's real-world efficacy and tolerability, we conducted a retrospective analysis of its first-line treatment outcomes.

Methods: We included patients with unresectable, locally advanced, or metastatic BTC treated with cisplatin, gemcitabine plus durvalumab. The primary endpoint was overall survival (OS).

Results: 33 patients were enrolled. Median OS was NR and median PFS was 7.6 months, after a median follow up of 13.5 months. The investigator-assessed overall response rate was 34.5 %, with stable disease in 53.0 % of patients. High baseline CEA levels were associated with poor survival. Any grade adverse events (AEs) occurred in 97 % of patients. Immune-related AEs (irAEs) occurred in 16 % (grade >2: 6 %). Presence of TP53 mutation was related to a worse OS, conversely the presence of ARID1A genomic alteration was related to a better PFS. A tendence toward a better OS was found for BRCAness patients which did not reach the statistical significance. On the other hand, BRCAness patients showed significantly higher PFS compared to no BRCAness patients Conclusion: This real-world analysis largely confirmed the TOPAZ-1 findings, supporting gemcitabine, cisplatin, and durvalumab as a first-line standard of care for patients with advanced BTC.

期刊介绍： Although laboratory and clinical cancer research need to be closely linked, observations at the basic level often remain removed from medical applications. This journal works to accelerate the translation of experimental results into the clinic, and back again into the laboratory for further investigation. The fundamental purpose of this effort is to advance clinically-relevant knowledge of cancer, and improve the outcome of prevention, diagnosis and treatment of malignant disease. The journal publishes significant clinical studies from cancer programs around the world, along with important translational laboratory findings, mini-reviews (invited and submitted) and in-depth discussions of evolving and controversial topics in the oncology arena. A unique feature of the journal is a new section which focuses on rapid peer-review and subsequent publication of short reports of phase 1 and phase 2 clinical cancer trials, with a goal of insuring that high-quality clinical cancer research quickly enters the public domain, regardless of the trial’s ultimate conclusions regarding efficacy or toxicity.
