Prognostic and Predictive Factors in Childhood Soft Tissue Sarcomas (MAKI-France)
The goal of this study is to better understand biological characteristics of non-rhabdomyosarcoma soft tissue sarcomas (NRSTS), a rare group of cancers that affect children, adolescents, and young adults. Researchers also aim to identify factors that could help predict how the disease will behave and respond to treatment.
The main questions it aims to answer are:
- Can advanced molecular analyses improve the classification and diagnosis of NRSTS?
- Can blood- and tumor-based biomarkers help predict outcomes and detect relapse earlier?
- Can researchers identify biological features that may guide future personalized treatments?
Participants aged 0 to 25 years with a recent diagnosis of NRSTS will take part in the prospective study. Researchers will collect archived tumor samples and blood samples during routine follow-up (approximately every 3 to 4 months) and will analyze these samples using advanced laboratory techniques. Clinical information will also be collected over a follow-up period of up to 4 years.
150 participants will be enrolled in the prospective part from 28 investigating centers across France.
Tumor samples already collected as part of your care, together with blood samples taken during follow-up visits, will be stored for future researches.
