About this study

Official title: Arm Function in Breast Cancer Survivors: Is There a Decrease in Maximal Capacity and Oxygen Utilization?

Breast cancer is the most common type of cancer among women worldwide. The incidence rate has reached approximately 16%. According to 2016 data from the Ministry of Health, the incidence of breast cancer in Turkey is 46.8 per 100,000 people and approximately 17,000 women are diagnosed with breast cancer each year. While breast cancer survival rate is 80% in developed countries, this rate varies between 40-60% in low-middle income countries. Survival can be increased with early diagnosis and more effective treatment methods. However, a wide range of treatment-related complications are observed during and/or after breast cancer treatment. Cancer survivors are exposed to a variety of direct (local/regional therapy, systemic therapy and supportive care) and indirect factors (modifiable and non-modifiable risk factors) that can have adverse effects on pulmonary, cardiovascular, hematologic and musculoskeletal components. Oxygen consumption in cancer patients may be adversely affected by aging, deconditioning, existing comorbidities, cancer pathophysiology and cancer treatments (surgery, radiation, chemotherapy and hormone therapy). Although decreased functional capacity is common after breast cancer treatment, there are few studies evaluating maximal arm exercise capacity with oxygen consumption.

Read the detailed description

In recent years, thanks to the increasing treatment possibilities with the developing technology, the majority of patients show good functional recovery after breast cancer. However, it has been reported that the treatments negatively affect the functional capacity of the upper extremities, daily life, work and social activities and reduce the quality of life. It has also been reported that breast cancer-related lymphedema (BCRL) may both cause and exacerbate treatment-related complications such as decreased functional capacity of the upper extremities and worsened quality of life after breast cancer treatments. In addition, it has been found that lymphedema decreases the muscle strength and range of motion of the limb in which it develops and causes an increase in symptoms such as pain, fatigue and discomfort. These complications caused by lymphedema lead to decreased functional level of the upper extremity, activity limitations and decreased quality of life. Cardiovascular health is negatively affected after breast cancer. Decreased cardiorespiratory performance also has direct consequences on daily task performance and therefore quality of life is negatively affected.

The gold standard method of measuring cardiorespiratory exercise capacity is cardiopulmonary exercise testing (CPET). This method determines the causes of limitation during exercise and gives maximal oxygen consumption (VO2max) as a measure of maximum performance. In cancer patients, the oxygen system may be adversely affected by chemotherapy. Effects of chemotherapeutic agents on respiratory, cardiac, blood, vascular or skeletal muscle functions have been observed, potentially contributing to impaired cardiorespiratory fitness. Cardiorespiratory function is not routinely measured at any stage of breast cancer treatment and CPET is rarely used in clinical settings. Although low VO2max measurements have been observed in intervention studies during breast cancer survivorship and these studies were conducted without the use of an arm ergometer, to our knowledge, there is very limited information on the impact of cancer treatment on cardiorespiratory fitness using gold standard testing methods.

Although decreased functional capacity is common after breast cancer treatment, there are few studies evaluating maximal arm exercise capacity with oxygen consumption.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Arm Exercise Capacity, Peak Oxygen Consumption (VO2peak)Diagnostic test

    peak arm exercise capacity

  • Muscle oxygenationDiagnostic test

    Muscle oxygenation (SmO2 ) was recorded using a device (Moxy, Fortiori Design LLC, Minnesota, USA) that measures local SmO2 in muscle capillaries using near-infrared spectroscopy (NIRS)

Study groups in NCT06018038
Study groupRoleWhat they receive
Breast Cancer GroupInclusion criteria for BCS were as follows: an age between 18 and 65 years; diagnosis of stage I-III BC; individuals with unilateral BC; ≥ 15 months must have passed since BC surgery; participants must have completed active cancer treatment (CT and/or RT) ≥ 6 months prior to joining the study; absence of BCRL; ability to read and understand questionnaires; and ability to cooperate with the assessments. Exclusion criteria for BCS included the presence of active infection, presence of BCRL; musculoskeletal or neurological conditions affecting exercise performance, symptomatic cardiovascular disease, neurological disorders, or any condition that could impair cognitive function.
Receives: Diagnostic Test: Arm Exercise Capacity, Peak Oxygen Consumption (VO2peak); Diagnostic Test: Muscle oxygenation
Control GroupInclusion criteria for healthy controls were an age between 18 and 65 years, the willingness to participate, the ability to read and understand questionnaires, and the ability to cooperate with the assessments. Exclusion criteria for healthy controls were the presence of orthopedic or neuromuscular conditions, chronic diseases, psychiatric or other mental conditions that could interfere with exercise testing.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Arm ergometer test

    estimated Oxygen Consumption (VO2max)

    Measured: One Year

Secondary outcomes (6)
  1. Upper Extremity Oxidative Muscle Metabolism

    Muscle Oxygen Saturation (SmO2 )

    Measured: One Year

  2. Peripheral Muscle Strength

    Hand grip strength by hand dynamometer

    Measured: One Year

  3. Upper extremity muscle endurance

    Functional Impairment Test-Hand, Neck, and Shoulder/Arm (FIT-HaNSA)

    Measured: one year

  4. Evaluation of Quality of Life

    European Organization for Research and Treatment of Cancer Quality of Life (EORTC QLQ-C30) All scores were linearly transformed to a 0 to 100 scale. A high or healthy level of functioning is represented by a high functional score

    Measured: One Year

  5. Fatigue Measurement

    Piper Fatigue Scale (PFS) Responses for each item It is evaluated between 0-10 points. The total fatigue score is based on 22 items scores are summed and divided by the number of items. Scale obtained from high scores indicate a high level of perceived fatigue shows.

    Measured: One Year

  6. anthropometric measurements

    Arm Circumference

    Measured: One Year

Questions about this trial

What is this clinical trial studying?

An observational study of Breast Cancer and Upper Extremity, run by Hacettepe University at 1 site in Turkey (Türkiye).

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 12 inclusion and 7 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 19 May 2026. 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 Turkey (Türkiye). 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?

Arm ergometer test (time frame: One Year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 19 May 2026.
