Brief Summary:
The MUTHEC project aims to describe the mutational and transcriptomic landscape of HCC treated by curative treatments (resection, radio frequency ablation, transplantation) as well as advanced HCC together with the analysis of circulating tumor DNA.

Condition or disease
HepatoCellular Carcinoma Cirrhosis

Detailed Description:

Scientific context

Hepatocellular carcinoma (HCC) is one of the leading causes of cancer death worldwide. A transcriptomic classification (G1-G6) described by our lab have underlined the heterogeneity of HCC and identified relationship between transcriptomic group and clinical and genetic features. Recently, a diagnostic and molecular algorithm has been developed to perform the diagnosis of benign and malignant hepatocellular tumors and assess the prognosis of resected HCC. Whole-exome sequencing has also identified new oncogenes and tumor suppressor genes in HCC. However, these studies have focused on HCC treated by liver resection and they have to be validated in biopsy and surgical pieces in larges series of patients treated by resection, liver transplantation and radiofrequency ablation (RFA). In addition, next-generation sequencing allows to sequence circulating tumor DNA in plasma of patients with advanced cancer but it has never tested in patients with HCC.

Description of the project The MUTHEC project involves 4 teams in France and aims to perform translation of molecular and genetic classification of HCC in clinical care.

First, the investigators want to draw a genetic landscape of HCC in different clinical settings. The investigators will sequence 30 genes, previously identified by whole exome sequencing, in a series of 120 HCC treated by RFA, 200 HCC treated by liver transplantation and 40 advanced HCC. The investigators also aim to validate our diagnostic and prognostic molecular algorithm (56 genes including the prognostic 5-gene score using quantitative RT-PCR) in different clinical settings and test their uses in formalin-fixed, paraffin-embedded (FFPE) tissues. In addition, the investigators will test surrogate markers of genetic alterations and oncogenic pathways using immunohistochemistry in these series of tumors. All the HCC will be reviewed by expert pathologist in order to perform genotype/phenotype classification. Lastly, the investigators want to conduct a pilot study to sequence circulating tumor DNA. The investigators will use next generation sequencing to detect in the plasma the somatic mutation observed in tumor biopsy. It will allow a non-invasive diagnosis of tumor mutation in the plasma of patients before and after treatment by RFA.

Expected results The investigators aim to extend our knowledge of HCC genetic alterations in the different types of curative treatment (resection, liver transplantation and RFA) and in advanced HCC. In addition, the investigators want to translate this classification using immunohistochemistry to facilitate it uses in routine. These results will be used in the future to identify subgroups predict to response to targeted treatment. In addition, the investigators will validate our diagnostic and prognostic molecular signature in different clinical situation and in FFPE samples. Assessment of prognosis after curative treatment will help to stratify adjuvant treatment in the future and guide therapeutic decision. Finally, sequencing circulating tumor DNA would allow monitoring somatic mutations ("liquid biopsy") after curative treatment and under the selective pressure of targeted therapies.

Group/Cohort
Patients with HCC
The cohort is composed of patients with HCC with available tumor and non tumor samples collected retrospectively. These patients have HCC of different stages (localized and advanced stages) It is an observational retrospective study.



Primary Outcome Measures :
  1. Genetic and transcriptomic landscape [ Time Frame: Up to 3 years ]
    Identification of the main genetic driver and transcriptomic subgroups among a large panel of HCC


Secondary Outcome Measures :
  1. Translation in immunohistochemical markers [ Time Frame: Up to 3 years ]
    The investigators aim to translate the major genetic drivers and oncogenic pathway dysregulated in HCC using immunohistochemistry. The investigators will test surrogate markers of the main genetic alterations and activation of oncogenic pathway using immunohistochemistry in HCC extensively reviewed by expert pathologists.

  2. Detection and sequencing of circulating tumor DNA as a liquid biopsy in HCC [ Time Frame: Up to 3 years ]
    The aim is to conduct a pilot and innovative study to detect mutations in DNA circulating in peripheral blood (ctDNA) in patients with early and advanced HCC. The results will be compared to that obtained in the tumor.

  3. Validation of the molecular classification by integrative analysis [ Time Frame: Up to 3 years ]
    At the end, the investigators aim to perform an integrative analysis of all the data generated by tumor analyses and collected in a database using the various approaches: clinical data, pathological and immunohistochemical features, molecular classification and genetic alterations.
