Our study aims to evaluate the benefit of the administration of immunotherapy (atezolizumab), in patients with hepatocellular carcinoma (HCC), prior surgical resection of the tumor.
HCC is the most prevalent primary liver cancer, responsible for nearly 800,000 deaths annually, making it the third leading cause of cancer-related mortality worldwide. Ablation by radiologic micro-waves or surgical resection represent at the moment the only curative therapies for early stages of the disease. Despite these curative options, HCC recurrence is frequent.
Recently, immunotherapy has demonstrated good results on patient overall survival for advanced stages of HCC in comparison to sorafenib. Because of the beneficial effect of immunotherapy on HCC, several groups have attempt to use it as adjuvant therapy in order to reduce the recurrence rate. However the results are at the moment controversial. One can hypothetize that postoperative inflammation and liver regeneration can negatively impact the effect of the immunotherapy. Therefore, the administration of the treatmeent before surgical resection could overcome this issue.
All adult patients undergoing liver resection for HCC at the Geneva University Hospitals (HUG), with prior informed and signed consent.
Patients of childbearing age must be willing to use a contraception at the day of inclusion and for at least 5 months after the last infusion.
Negative pregnancy test at inclusion
Patients will require to be eligible for surgical resection according to the BCLC guidelines (very early to early stage with preserved liver function and good patient condition) (4).
Patients who do not ultimately undergo liver resection due to unforeseen reasons (this happens rarely, such as in the presence of unexpected HCC progression discovered during surgery).
Patients with an ongoing pregnancy (an unlikely event, as non-surgical HCC treatments would be prioritized in such cases).
Patients unable to follow procedures due to language barriers, insufficient comprehension of project language, or unable to give consent.
Patients <18 years.
