800-Patient study aims to tailor sarcoma treatment
NCT ID NCT07432932
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is collecting tissue samples and medical data from 800 high-risk sarcoma patients to develop personalized treatment approaches. Researchers will analyze genetic and protein profiles to better predict which patients benefit from chemotherapy before surgery. The goal is to create a tool that helps doctors choose the most effective treatment for each individual.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could lead to personalized chemotherapy plans for high-risk sarcoma patients, potentially improving survival and reducing recurrence.
- What could go wrong
- This is an observational study, not a treatment trial. It may not directly benefit participants, and the findings might not translate into clinical practice for years.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Written informed consent for the prospective cohort * Histopathological diagnosis of high-risk soft tissue sarcoma and one of the following subtypes: DDLPS, LMS, SS, vascular sarcomas or MPNST. Other subtypes may be included with PI approval. * High-risk sarcoma definition: * Greater than 5cm or Grade 3 * Deep anatomic location * Have disease amenable to biopsy o Patients who are not amenable to repeat biopsy at baseline can be reviewed with the local site PI for consideration of inclusion to the study * Resectable tumour * Measurable disease by RECIST 1.1 * Aged ≥ 18 years * WHO performance status 0-2 * For patients receiving NCT, medically fit enough, with adequate organ function, to undergo neoadjuvant chemotherapy * Patients medically fit enough to undergo surgical resection * Capable of giving written informed consent (for prospective cohort) and comply with the study schedule * Patients may also participate in the STRASS 2 trial Exclusion Criteria: -Prior invasive malignancy in last 5 years, low risk malignancies in the last 5 years may be reviewed by the PI. * Known additional malignancy that is progressing or requires active treatment * Metastatic disease not amenable to curative intent local therapy * Any active uncontrolled medical conditions
