Exercise Testing for Early Stage Breast Cancer Patients Receiving Radiation Treatment
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
Many patients receiving radiation therapy for breast cancer experience fatigue although doctors do not fully understand why. The purpose of this study is to test if patients who experience fatigue during radiation treatment for breast cancer have changes in their capability to perform exercise on a treadmill.
fatigue measurement using the 13-item FACIT-fatigue scale [ Time Frame: 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.

Layout table for eligibility information
Ages Eligible for Study:
18 Years to 80 Years (Adult, Older Adult)
Sexes Eligible for Study:
Accepts Healthy Volunteers:
Patients who are undergoing or have recently completed radiotherapy for breast cancer (in the last 3 months) will be assessed in outpatient clinics of the Radiation Oncology Department of MSKCC. The protocol is available for consenting only at OneMSK Sites Basking Ridge, Rockville Center, Commack, Monmouth and Westchester.
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).
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)
Uncontrolled arrhythmia causing symptoms or hemodynamic compromise
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
Room air desaturation at rest ≤ 85%
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
