简要总结
This trial is a multicenter, prospective cohort study aiming to describe molecular profiles of soft tissue sarcoma (STS) with complex genomic profiles in particular to assess the incidence of NTRK1/2/3, ROS1 or ALK gene fusions to direct such patients through an ongoing clinical trial with entrectinib when appropriate. An exploratory translational program is also correlated to this trial in order to analyse immune gene expression.
详细描述
Following inform consent form (ICF) signature, a formalin-fixed and paraffin-embedded (FFPE) tumor block (archival or a dedicated freshly collected tumor biopsy) will be collected for all enrolled patients and centralized at the biological resources platform of the Centre Léon Bérard.
At reception, a central pathological review will be performed to confirm if quality and quantity of material is acceptable: all tumor sample should present at least 20 % (ideally 30 %) of tumor cells and have a surface area > 5 mm2 (optimal condition is a surface area of 5-25 mm2). If the quality and quantity of tumor sample do not meet the standards, patients will be considered as "screening failure". If standards are met, inclusion will be confirmed and molecular screening will be initiated as well as the translational research program.
The molecular screening to detect NTRK1,2,3, ROS1 or ALK gene rearrangements will be a two-step process, consisting of :
- First, immunohistochemistry (IHC) assay to detect protein expression of TRKA/B/C (encoded by NTRK1,2,3), ROS1 or ALK. Only positive IHC samples will continued the 2nd step of molecular screening. Negative IHC patients do not require further NTRK, ROS or ALK gene rearrangement testing; however tumor samples will be further used for additional translational research program presented in Section VII and data about the clinical evolution of these patients will be collected
- Second, RNAseq analysis will be performed on positive IHC specimens to detect specific rearrangements in the NTRK1,NTRK2, NTRK3, ROS1 or ALK genes.
- Following molecular analyses, screening results will be immediately (within 24 hours) communicated to investigators, GSF-GETO Network and Ignyta representatives in order to recommend patients with NTRK1, NTRK2, NTRK3, ROS1 or ALK rearrangement for formal eligibility determination for potential enrolment in a clinical trial in particular with entrectinib (STARTRK-2; NCT02568267).

结局指标
主要结局
the proportion of patients with NTRK1/2/3, ROS1 or ALK gene fusions (95% confidence interval)
时间窗: 24 months
Such molecular pre-screening will allow to direct eligible patients with sarcomas harboring an NTRK1/2/3, ROS1 or ALK fusion to a clinical trial with entrectinib, when judged appropriate by the patient's treating oncologist. Depending of the molecular alterations, other therapeutic options could be envisaged.
次要结局
- Proportion of patients with NTRK1/2/3, ROS1, or ALK gene fusion per histological sub-types of STS with complex genomics(24 months since first inclusion)
- anti-cancer treatments initiated since inclusion.(36 months)
- Clinical characteristics of patients with NTRK1/2/3, ROS1, or ALK gene fusion versus patients with no NTRK1/2/3, ROS1, or ALK gene fusion.(24 months since first inclusion)
- Overall survival (OS)(36 months)
