<p>Significant benefit of nivolumab combining radiotherapy in metastatic gallbladder cancer patient with strong PD-L1 expression: a case report</p>

Abstract

To our knowledge this is the first case presenting significant nivolumab response in a Chinese GBC patient. This remarkable response was most likely associated with the strong PD-L1 expression, and indicated that PD-L1 expression could be considered as a biomarker for nivolumab treatment in metastatic gallbladder cancer. However, more studies are needed for validation.
