Characterizing Chemo-Radiotherapy Treatment-Related Cardiac Changes in Non-metastatic, Non-recurrent Lung and Esophageal Cancer Patients

2019-12-06 00:24:50 | BioPortfolio


This trial studies cardiac changes after radiation or chemo-radiation for the treatment of lung or esophageal cancer that has not spread to other places in the body (non-metastatic) or has not come back (non-recurrent). Continuous cardiac monitoring with an implanted device may help to identify cardiac changes that would remain unnoticed, and facilitate the treatment of these early cardiac changes as part of standard care.



I. To determine the 12-month cardiac event rate after radiation or chemo-radiation for the treatment of lung or esophageal cancer.


I. Define the spectrum of cardiac toxicity among chemoradiotherapy (CRT) patients at highest risk of cardiac toxicity.

II. Establish the timeline of cardiac toxicity development and identify early predictive findings of permanent damage.

III. Characterize the areas of the heart at highest risk for persistent cardiac damage.

IV. Identify a dose response threshold for radiotherapy (RT) damage in different areas of the heart.

V. Improve survival by alerting the cardiology team of the need for life-saving standard of care interventions.

VI. Describe medical interventions employed for the cardiac events identified in the study.


Patients receive cardiac monitor implants then undergo standard of care RT or CRT at the discretion of the treating physician. Patients also undergo blood sample collection at baseline, 4 weeks, 3, 9, and 12 months.

After completion of study treatment, patients are followed up at 4 weeks, 3, 9 and 12 months post RT.

Medical and Biotech [MESH] Definitions

The treatment of a disease or condition by several different means simultaneously or sequentially. Chemoimmunotherapy, RADIOIMMUNOTHERAPY, chemoradiotherapy, cryochemotherapy, and SALVAGE THERAPY are seen most frequently, but their combinations with each other and surgery are also used.

Preliminary cancer therapy (chemotherapy, radiation therapy, hormone/endocrine therapy, immunotherapy, hyperthermia, etc.) that precedes a necessary second modality of treatment.

Organs which might be damaged during exposure to a toxin or to some form of therapy. It most frequently refers to healthy organs located in the radiation field during radiation therapy.

Drugs used to protect against ionizing radiation. They are usually of interest for use in radiation therapy but have been considered for other, e.g. military, purposes.

Combined chemotherapy and radiotherapy given to augment some other form of treatment such as surgery. It is commonly used in the therapy of cancer.
