About this study

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.

Read the detailed description

Rationale: Anthracyclines and platinum-based drugs are widely used chemotherapeutic agents, offering a favorable approach to treating solid and hematological cancers. However, treatment with these drugs can lead to severe toxicities, which last for many years. These chemotherapeutic agents are known to have detrimental effects on skeletal and cardiac muscles. Loss of skeletal muscle mass is associated with treatment modifications (i.e., dose delay/reduction/discontinuation), increased levels of fatigue, decreased quality of life (QoL) and shorter survival. Cardiomyopathy might lead to chronic heart failure in the long-term, which negatively affects prognosis as well. Preclinical studies investigating underlying mechanisms of these detrimental effects suggest that mitochondrial dysfunction plays a key role. However, human data is lacking due to the need of invasive repeated muscle biopsies. Phosphorus (31P) Magnetic Resonance Spectroscopy (MRS) is an innovative, non-invasive technique, which enables repeated measures of skeletal and cardiac muscle mitochondrial energy metabolism.

Hypothesis:

In this study we hypothesize that patients treated with anthracyclines and/or platinum-based agents will show decreased mitochondrial function in skeletal and cardiac muscle tissue following chemotherapy treatment.

Objective:

To demonstrate the ability of using non-invasive 31P-MRS to monitor changes of in vivo markers of mitochondrial function in skeletal and cardiac muscles (i.e., skeletal muscle PCr recovery rate constant and cardiac PCr/ATP ratio) in patients treated with anthracyclines and/or platinum-based agents. Furthermore, we will assess the feasibility of undergoing the study measurements for patients during intensive cancer treatment and explore the association between changes in in vivo measured mitochondrial function in skeletal and cardiac muscle tissue and changes in muscle mass, physical fitness, muscle strength, physical activity levels measured by Fitbit, chemotherapy completion rate and patient-reported outcomes, including physical activity, fatigue and quality of life.

Study design: Cohort study.

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

Main study parameters/endpoints:

The main study parameters are differences in skeletal muscle PCr recovery rate constant and cardiac PCr/ATP ratio. These parameters will be compared within-patients before, halfway during and after completion of chemotherapy treatment.

Nature and extent of the burden and risks associated with participation and benefit:

Included patients will visit the UMC Utrecht 3 times (i.e., before, halfway during and after completion of chemotherapy treatment). During these visits, participants will undergo 31P-MRS imaging of the calf muscles and of the heart at 7 Tesla. During the calf muscle scan, patients will be asked to perform a mild exercise challenge (i.e., dynamic plantar flexions). 7T 31P-MRS is a safe and reliable technique for subjects without contra-indications for undergoing MRI. Possible side-effects are limited to short-term vertigo and nausea. In addition, anthropometrics will be measured and small tests to evaluate muscle strength and physical performance will be performed. Participants will be asked to complete questionnaires regarding physical activity, quality of life and fatigue. Finally, patients will be asked to wear a Fitbit, provided by the study team, to objectively assess their levels of physical activity.

Subjects will not experience direct benefits by participating in this study. By the end of the study, the investigators will demonstrate the ability to non-invasively monitor skeletal and cardiac muscle mitochondrial damage using 31P-MRS, which is a pre-requisite to assess the efficacy of (non-)pharmacological interventions.

  5. Changes in skeletal muscle area in cm2

    Assessed through routine CT-scans

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

  6. Changes in subjective physical activity levels (min/week moderate-to-vigorous physical activity)

    Physical activity levels will be assessed subjectively using the Short QUestionnaire to ASsess Health-enhancing physical activity (SQUASH)

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

  7. Changes in objective physical activity levels (min/week moderate-to-vigorous physical activity)

    Participants are provided with a Fitbit Inspire HR and are asked to wear these as much as possible during the whole study period. The Fitbit continuously registers the heart rate. Based on this, physical activity levels will be calculated.

    Measured: Throughout the whole study, but of particular interest are the 9th week after baseline and 18th week post-baseline

  8. Changes in health-related Quality of Life

    Measured using the core EORTC Quality of life questionnaire (QLQ-C30). The results of the questionnaire can be used to calculate a summary score, global health status, functional subscales and symptom subscales. For the summary score, global health status and functional subscales, a higher score is a better outcome, whilst for the symptom subscales, a lower score is a better outcome. All scores range from 0 to 100.

    • Global health status
    • Summary score

    Functional scales:

    • Physical functioning
    • Role functioning
    • Emotional functioning
    • Cognitive functioning
    • Social functioning

    Symptom scales:

    • Fatigue
    • Nausea and vomiting
    • Pain
    • Dyspnoea
    • Insomnia
    • Appetite loss
    • Constipation
    • Diarrhoea
    • Financial difficulties

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

  9. Changes in lymphoma specific symptoms

    Measured using the add-on of the abovementioned EORTC QLQ-C30, which is specifically developed for non-Hodgkin lymphoma patients (EORTC QLQ-NHL-HG29). A higher score depicts worse outcomes. All scores range from 0 to 100.

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

  10. Changes in fatigue

    The EORTC provides several questionnaires to asses the quality of life of cancer patients. To assess fatigue the EORTC developed a specific fatigue questionnaire (QLQ-FA12). This questionnaire can be used to assess different dimensions of fatigue. A lower score depicts a better outcome. All scores range from 0 to 100.

    Fatigue dimensions:

    • Physical fatigue
    • Emotional fatigue
    • Cognitive fatigue

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

  11. Changes in skeletal muscle end-exercise pH

    Assessed through 31P-MRS imaging.

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