Study of Exosomes in Monitoring Patients With Sarcoma (EXOSARC) (EXOSARC)
Sarcomas are rare cancers with a high risk of metastatic progression and a major pejorative factor with respect to patient survival. The estimation of the metastatic risk of sarcomas is very complex given the histological heterogeneity of this entity. It is therefore essential that, at diagnosis, a reliable evaluation of this metastatic potential be made, in order to adapt the therapeutic strategy as well as possible.
It has recently been discovered that sarcomas secrete many exosomes that appear to play an important role in tumorogenesis, growth, tumor progression and the onset of metastases. They contain many proteins and nucleic acids (DNA, RNA, microRNA), reflecting the characteristics of the tumor. It has been shown that the amount of exosomes can be correlated with the grade of malignancy of the tumor. Present in the blood, exosomes offer the possibility of non-invasively analyzing the molecular information of the cancer cell. As a result, the study of serum exosomes derived from sarcomas has a high potential as a liquid biopsy to evaluate cancer pathogenesis, progression, and treatment efficacy.
The purpose of this study is to demonstrate in patients with sarcomas that exosomes can be used to monitor their disease and be used as a predictor of the risk of recurrence.
Study Overview
Detailed Description
The main objective of this pilot study is to quantify exosomes and analyze their protein and RNA content in patients with sarcoma with disease:
- localized before and after treatment with surgery,
- localized for which neoadjuvant chemotherapy is being considered
- metastatic or locally advanced cancer before and after treatment with first-line chemotherapywhich may include neoadjuvant therapy
The secondary objectives are:
- Determine whether the initial exosome concentration and the protein and RNA profile they contain vary with the localized or metastatic stage of the disease.
- Determine if the exosome concentration as well as the protein and RNA profile they contain varies after treatment.
- Determine if the initial exosome concentration (at T0) is associated with a response to treatment.
- Determine whether the change in exosome concentration before and after treatment is associated with a response to treatment.
- Identify a protein marker or RNA associated with a treatment response (marker present at T0 or occurring during follow-up).
