About this study

Official title: Development of an MRI-based Radiomic Model for Non-invasive Tumor Grading of Soft Tissue Sarcomas.

Radiomics is defined as a quantitative high-throughput analysis of imaging data combined with model development aiming to predict biological correlates or clinical endpoints. The investigators of this study hypothesize that radiomic features may correlate with pathology-defined tumor grading in soft tissue sarcoma patients. The aim of this study is to develop a predictive radiomics model for tumor grading determination.

Read the detailed description

Soft tissue sarcomas (STS) constitute an overall rare malignant entity comprising 1% of all cancers with a yearly incidence rate of 3.8 per 100.000 inhabitants. Therapy decisions are made using clinical and pathological determinants defined by the American Joint Committee on Cancer (AJCC). It involves the TNM staging system that classifies STS by their tumor size (measured as maximal diameter), pathological tumor grading defined by the French Fédération Nationale des Centres de Lutte Contre le Cancer (FNCLCC) and the occurrence of nodal or distant metastases.

For the guidance of therapy, the most important factor constitutes tumor grading. In "low-grade" sarcomas (G1), surgical resection is often sufficient for durable tumor control. In "high risk" STS, however, resection of the tumor is combined with radiotherapy improving locoregional control and eventually survival.

Currently, invasive biopsies followed by pathological work-up are necessary to determine tumor grading. However, bioptic specimens are always restricted to small tumor subvolume.

Medical imaging-based analyses constitutes an alternative tool to characterize tissue. Recent developments in quantitative image analysis and data science have led to the evolvement of "Radiomics". It is defined as an algorithm-based large-scale quantitative analysis of imaging features. It should be considered as a two-step process with (1) extraction of relevant imaging features, and (2) incorporating these features into a mathematical model to ultimately predict patient or tumor-specific outcomes. In previous scientific studies, radiomic models have been associated with survival, tumor progression, and molecular changes including genetic mutations or expression profiles as shown in multiple malignant entities. In addition, radiomic models were able to predict tumor grading e.g. for gliomas, meningiomas, hepatocellular carcinoma or pancreatic neuroendocrine tumors. In contrast to pathology, quantitative image analysis (radiomics) has the principal advantage of analyzing the whole tumor.

In this study, the investigators are aiming to correlate radiomic features with tumor grading of STS. The ultimate goal is to develop a prediction model to non-invasively classify tumor grading. In a first step, the focus will be laid on differentiating "low-grade" and "high-grade" STS. In a second step, "high-grade" STS will be divided into G2 and G3 tumors.

To this end, the investigators will retrospectively analyze a patient cohort of 138 patients (139 tumors) with known tumor grading and available pre-therapeutic MRI-scans. As secondary endpoint overall survival will be determined for all patients. An independent patient cohort from the University of Washington (139 patients) will be used for external validation of the developed models.

Questions about this trial

What is this clinical trial studying?

An observational study of Sarcoma, Soft Tissue, run by Technical University of Munich at 1 site in Germany.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 10 Apr 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Germany. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Pathological tumor grading (time frame: Baseline). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03798795, which also lists 3 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Apr 2019.
