NCT05739084

Brief Summary

To date, the radiation oncologist are missing biomarkers predictive of response/resistance to RT in order to identify patients who may benefit from RT and personalize the RT schedule. Our proposal is to conduct a cohort study aiming at identifying transcriptomic biomarkers predictive of sensitivity and/or resistance to RT in limbs STS patients

Outcome Measures

Primary Outcomes (1)

  • To define a transcriptomic signature of histological response to radiotherapy in STS patients using the percentage of residual viable cells as a clinical meaningful endpoint

    Gene expression signature using RNAseq correlated to the percentage of residual viable cells on surgery specimen to define histological response.

    36 months

Secondary Outcomes (1)

  • To identify biomarkers of sensitivity or resistance to radiotherapy in STS patients using additional clinical endpoints

    36 months

Study Arms (2)

Retrospective cohort

A total sample size of 200 patients is expected in the retrospective thanks to the NETSARC/ CONTICABASE databases (French sarcoma reference network)

Radiation: pre-operative radiationProcedure: Standard surgery after rpreoprative radiation

Prospective cohort

To ensure an external validation, patients from NETsarc centers experiencing preoperative RT will be prospectively accrued and transcriptomic signature will be tested. Up to 100 patients will be enrolled in this prospective cohort.

Study Population

Patients with Soft tissus sarcoma who underwent/undergo to preoperative Radiation and for whom resected tumour specimen is available.

You may qualify if:

  • Male and female ≥ 18 years at time of non-opposition to participate to the study
  • Patient with documented non-opposition to participate to the study.
  • Patient with histologically and cytologically confirmed diagnosis with STS (..)
  • Patient with availability of FFPE tumor block from initial diagnosis biopsy (mandatory) and surgery specimen (optional).
  • Patients with tumor FFPE samples prepared with the last 4 years
  • Patient with evaluable tumor sample meeting the following quality/quantity control criteria (..)

You may not qualify if:

  • Patients with metastatic soft tissue sarcoma at diagnosis
