About this trial

This is an interventional diagnostic trial for Rhabdomyosarcoma

Eligibility Criteria

6 Years - 18 Years (Child, Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Referred with a confirmed or suspected sarcoma tumor (rhabdomyosarcoma [RMS] or non-rhabdomyomatous sarcoma) presenting with an extra-osseous component;
  • Candidate for neoadjuvant therapy that will consist of standard systemic chemotherapy with or without radiation therapy

Exclusion Criteria:

  • Patients with general contraindications for an MRI scan (metal foreign body, pacemaker, inability to tolerate an examination without sedation);
  • Patients with a known immunodeficiency/sickle cell disease/collagen vascular disease/another malignancy;
  • Patients with no clinical indication for neoadjuvant therapy prior to surgery;
  • Patients with chronic pulmonary disease;
  • Patients with other diagnosis confirmed after initial suspicion of RMS or non-RMS.

Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

FAZA - BOLD- DW- MRS

Arm Description

18F-FAZA (F18-Fluoroazomycin Arabinoside) is a radioactive agent developed as a non-invasive probe for the assessment of cellular hypoxia. 18F-FAZA Injection is indicated in a single dose of (5.2 MBq/kg [0.14 mCi/kg]) Route/method of administration: intravenous injection. Blood Oxygen Level Dependent [BOLD], Diffusion-Weighted [DW] MRI, MR Spectroscopy [MRS]

Outcomes

Primary Outcome Measures

Number of participants with response to therapy
Response will be assessed by measurements of tumor volume, percentage of BOLD signal changes, percentage of tumor necrosis, apparent diffusion coefficient, concentration of high-energy and low-energy phosphates in tumor and necrotic areas and 18F-FAZA uptake.

Secondary Outcome Measures

Associations between post-neoadjuvant therapy imaging measurements and surgical / histochemical outcomes in the residual tumor.

5. Study Description

Brief Summary
This study will test the feasibility of using novel/existing imaging technologies focused on hypoxia measurements to determine "response to therapy" in pediatric soft tissue sarcomas as a pilot study. Specifically, the investigators will compare the sensitivity of Blood Oxygen Level Dependent [BOLD], Diffusion-Weighted [DW] MRI, Magnetic Resonance Spectroscopy (MRS) and 18F-FAZA PET-MRI with that of conventional MRI to detect measurement changes between the start and completion of neoadjuvant therapy ("response to therapy") in children and adolescents (7-18 years) with suspicion of sarcoma tumors. Clinicians and scientists may use results of the proposed hypoxia-imaging surrogate markers to adjust/modify therapeutic schemes to patients on a personalized basis.

Intervention Type
Drug
Intervention Name(s)
18F-FAZA (F18-Fluoroazomycin Arabinoside)
Other Intervention Name(s)
18F- FAZA
Intervention Description
Intravenous administration of a hypoxia marker, 18F- Fluoroazomycin arabinoside (FAZA), before a PET-MR imaging in order to identify areas of lower oxygen content on samples of a tumour.
Intervention Type
Diagnostic Test
Intervention Name(s)
Blood Oxygen Level Dependent [BOLD] MRI
Intervention Description
BOLD is a non-invasive T2*-weighted MRI technique that is sensitive to the microvascular deoxyhemoglobin concentration. BOLD has the potential to monitor changes in tissue oxygenation in response to a gas breathing challenge to induce contrast.
Intervention Type
Diagnostic Test
Intervention Name(s)
Diffusion-Weighted [DW] MRI
Intervention Description
DW MRI is a non-invasive technique that provides quantitative biophysical information about the movement of water in tissues and reflects the anisotropy of normal and pathologic cells
Intervention Type
Diagnostic Test
Intervention Name(s)
Magnetic Resonance Spectroscopy [MRS]
Intervention Description
MRS is a non-invasive imaging technique that enables the generation of spectral profiles of low molecular weight metabolites that reflect status of a tissue
