• Study Type: observational
• Target: 12

• Sites: 4

Brief Summary

The goal of this observational study is to demonstrate the ability of using non-invasive Phosphorus (31P) Magnetic Resonance Spectroscopy (MRS) to monitor changes of in-vivo markers of mitochondrial function in skeletal and cardiac muscles in muscles in patients with cancer treated with anthracyclines and/or platinum-derivates. The main question it aims to answer is: • Can 31P-MRS be used to monitor changes of in vivo markers of mitochondrial function in skeletal and cardiac muscles in patients with cancer undergoing treatment with anthracyclines and or platinum derivates? To be able to answer this main question, participants will undergo 31P-MRS imaging of the calf muscles and of the heart 3 times during the study period.

Conditions

Doxorubicin Induced Cardiomyopathy; Chemotherapeutic Toxicity; Anthracyclines

Outcome Measures

Primary Outcomes (1)

Other Outcomes (2)

• Changes in weight (kg)

  Baseline, halfway (R-)CHOP treatment (+/- 9 weeks), after (R-)CHOP treatment (+/- 18 weeks)

• Height (cm)

  Baseline, halfway (R-)CHOP treatment (+/- 9 weeks), after (R-)CHOP treatment (+/- 18 weeks)

Study Arms (1)

Study population

Patients scheduled for cancer treatment with anthracyclines and/or platinum-based agents.

Study population

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

Patients will be recruited at UMC Utrecht, Diakonessenhuis Utrecht and possibly other hospitals in the vincity of the UMC Utrecht. The aim is to include 12 patients with with any type of cancer scheduled to receive treatment with anthracyclines and/or platinum-based drugs at any of the recruiting hospitals.

You may qualify if:

• Age ≥ 18 years
• Patients diagnosed with any type of cancer, who are scheduled to receive chemotherapy treatment containing at least anthracyclines and/or platinum-based drugs.
• WHO-performance score 0-2.
• Patients with sufficient Dutch writing and reading skills.
• Written informed consent.

You may not qualify if:

• Contra-indications for 7T MR scanning, including patients with a non-MRI compatible pacemaker, cochlear implant or neurostimulator; patients with non-MR compatible metallic implants in their eye, spine, thorax or abdomen; patients with a non-MR compatible aneurysm clip in their brain; patients with claustrophobia, and/or severe obesity.
• Any circumstances that would impede adherence to study requirements or ability to give informed consent.
• Medical disorders affecting mitochondrial function; e.g., spinal muscular atrophy.
• (Other) relevant medical disorders; e.g., comorbidities affecting exercise tolerance.
• Being under examination for non-diagnosed disease at the time of investigation.
