Exercise Testing for Early Stage Breast Cancer Patients Receiving Radiation Treatment

Recruitment & Eligibility

Inclusion Criteria

Female
ECOG performance status 0 or 1
Medical clearance from attending radiation oncologist or medical oncologist to undergo a symptom-limited CPET
Currently undergoing intact breast radiotherapy for early stage breast cancer (including TisN0, T1N0, T2N0) or has completed intact breast RT in the last 3 months.
Receiving or received a prescribed dose of 4240 cGy in 16 fractions to the whole breast without treatment directed at nodal basins. Patients may also be receiving or have received a boost to the lumpectomy bed at the discretion of the treating physician.
Subjects may be treated in the supine or prone position at the discretion of the treating physician.
Subjects may be treated with or without a deep inspiratory breath hold technique at the discretion of the treating physician.
Identified by the treating radiation oncologist as having significant treatment-related fatigue or minimal treatment-related fatigue and not simply baseline fatigue. A score of "0" on the RTOG fatigue scale will be considered minimal fatigue, while a score of "2" or greater will be considered significant fatigue (moderate fatigue causing difficulty performing some ADLs).

Exclusion Criteria

Currently undergoing post-mastectomy radiation
Has received chemotherapy previously or has a plan to receive chemotherapy during the timeframe of study assessment.
Any of the following absolute contraindications to CPET, as per American Thoracic Society (ATS) recommendations
- Acute myocardial infarction (within 3-5 days of any planned study procedures)
- Unstable angina
- Uncontrolled arrhythmia causing symptoms or hemodynamic compromise
- Recurrent syncope
- Active endocarditis
- Acute myocarditis or pericarditis
- Symptomatic severe aortic stenosis
- Uncontrolled heart failure
- Acute pulmonary embolus or pulmonary infarction within 3 months of any planned study procedures
- Thrombosis of lower extremities
- Suspected dissecting aneurysm
- Uncontrolled asthma
- Pulmonary edema
- Room air desaturation at rest ≤ 85%
- Respiratory failure
- Acute non-cardiopulmonary disorders that may affect exercise performance or be aggravated by exercise (i.e. infection, renal failure, thyrotoxicosis)
- Mental impairment leading to inability to cooperate

Primary Outcome Measures

Name	Time	Method
fatigue measurement using the 13-item FACIT-fatigue scale	1 year	Fatigue will be assessed using the 13-item FACIT-fatigue scale for the assessment of fatigue in cancer patients.24 The FACIT-Fatigue is a validated questionnaire that was originally developed for the precise evaluation of fatigue levels in cancer patients with anemia. It consists of 13 questions using a 5 point scale (0=not at all; 1 = a little bit, 2 = somewhat, 3 = quite a bit and 4 = very much). It has been used frequently in the clinical trial setting (please see appendix 1). Responses to each question are added with equal weight to obtain a total score. The range of possible scores is 0-52, with 0 corresponding to the highest level of fatigue and 52 corresponding to the lowest level of fatigue.
