Establishment of a Prospective Clinical-biological Database

Official title

Development of a Monocentric and Prospective Clinical and Biological Database in Sarcoma

Overview

A Clinical and Biological Database will provide to the scientific community a collection of blood and tissues with clinical data to improve knowledge about cancer and help to develope new cancer treatments. This database is specific to Sarcoma

Detailed description

Liposarcomas (LPS) are soft tissue tumours of mesenchymal origin. The most common histological subtypes, represented by well differenciated Lipsarcomas (WD-LPS) and dedifferenciated (DD-LPS), are characterized by the quasi-systematic amplification of the q13-15 of chromosome 12 containing the Mdm2 gene.

The systematic amplification of the Mdm2 gene is such that it is used clinically to distinguish WD/DD-LPS from other types of sarcomas. These observations raise key questions about the high selection pressure that leads to the almost systematic amplification of Mdm2 during the development of these LPS.

Mdm2 is an oncoprotein whose roles in p53 tumour suppressor degradation are broadly described. However, the different inhibitors targeting this interaction were disappointing in clinical trials.

Recently a team from the U1194 INSERM unit of the IRCM which collaborates in this project showed by a pan-genomics analysis, that Mdm2 is recruited to chromatin within a multiproteic complex having as target a transcriptional program involved in the metabolism and in particular in the biosynthesis of the serin.

This clinical-biological basis will allow the continuation of this research project on liposarcomas and the development of new research projects on other histological types of sarcomas.

Interventions

• Other Paraffin tissue samples
  Paraffin tissue samples collected during surgery (neoplasic tissue and normal tissue
• Other blood sample
  MDM2 project : Blood samples collected at different times : Before the surgery, and 1 month after the surgery circulant DNA project : Blood samples collected at different times : Before the surgery, and 1 month after the surgery radiotherapy toxicity : Blood samples collected before the radiotherapy

Primary outcome measures

• Establishment a clinical and biological database will provide to the scientific community a collection of blood and tissues with clinical data to improve knowledge about sarcoma [Time frame: Until the study completion : 5 years]
• Establishment a clinical and biological database will provide to the scientific community a collection of blood and tissues with clinical data to improve knowledge about sarcoma [Time frame: Until the study completion : 5 years]
