Gustavo Viani: A New Era for Biliary Tract Cancers

Gustavo Viani, Associate Professor at Faculty of Medicine of Botucatu, São Paulo State University (UNESP), shared on LinkedIn: about a recent paper by Han Xiao et al. published on JAMA Network:

“A New Era for Biliary Tract Cancers: ACCORD Trial Proves the Power of RT + Immunotherapy

Objective

  • To assess whether camrelizumab + capecitabine + radiotherapy improves survival compared with observation after curative surgery for EHC and GBC.

Methods

  • Design: Randomized clinical trial (ACCORD, 2020–2022)
  • Population: 93 patients with resected EHC/GBC
  • Intervention: Camrelizumab every 3 weeks → capecitabine with concurrent RT
  •  Control: Observation only
  • Endpoints: Overall survival (OS, primary), recurrence-free survival (RFS), safety

Results

  • OS at 3 years: 58% vs. 31% (HR 0.43; p=0.004)
  • RFS at 3 years: 40% vs. 17% (HR 0.46; p<0.001)
  •  Well tolerated: no treatment-related deaths, only 13% with delay in immunotherapy

Clinical Impact

  • This trial provides robust evidence that combining immunotherapy with adjuvant chemoradiation significantly increases survival in this challenging setting. It opens a new path for standardizing adjuvant therapy in resectable biliary tract cancers (EHC/GBC), historically lacking effective strategies.”
