Overview
Brief Summary
To validate a new method for assessing perioperative risk in the cancer patient undergoing major cancer surgery.
In this proposed study researchers will:
- Measure preoperative energy reserve capacity (fitness)
- Determine if postoperative morbidity is a function of perioperative cardiopulmonary gas exchange metabolism
Detailed Description
Primary Objective: • To characterize the effects of neoadjuvant therapy (chemotherapy, radiation therapy, and/or immunotherapy) on functional capacity in esophageal and lung cancer participants as measured by gas exchange parameters (%predicted AT, %predicted P-VO2, VO2 at AT \& peak exercise, oxygen pulse, ΔVO2/ΔWR, ΔVE/ΔVCO2) obtained from CPET before and after neoadjuvant therapy. Secondary Objectives: • To characterize changes in CPET measures in participants treated with chemotherapy, radiation therapy, and/or immunotherapy followed by surgery and correlate these changes with postoperative outcome.
Investigators
Eligibility Criteria
Inclusion Criteria
- •Participants 18 years of age or older.
- •Participants with newly diagnosed esophageal and lung cancer undergoing neoadjuvant chemotherapy, radiation therapy, and/or immunotherapy.
- •Participants who have signed the consent form to participate in the study.
- •Participants must have been evaluated in the Perioperative Evaluation and Management (POEM) Center or by a staff Anesthesiologist.
- •All laboratory and diagnostic evaluations required or used to evaluate the patient must be completed. All participants must be approved to undergo anesthesia by the standards of the POEM Center.
- •No samples belonging to vulnerable populations (children, pregnant women, cognitively impaired adults or prisoners) will be allowed from participation.
Exclusion Criteria
- •Participant is under age
- •Participant is unwilling to sign consent.
- •Participant is unable to exercise (bedridden or wheel chair bound).
- •Participant is enrolled in another study deemed by the investigator to affect oxygen metabolic efficiency and not presently the standard of care at MDACC.
- •Participant's condition is deemed unsatisfactory for surgery after the preanesthetic evaluation.
- •Participant has had a myocardial infarction within three months of the preanesthetic evaluation or presents with new or unstable angina.
- •Participant has a history of a cerebrovascular accident or transit ischemic attacks within three months of the preanesthetic evaluation.
- •Participant has a history of a pulmonary embolic event within three months of the preanesthetic evaluation.
- •Participant is known to have acute or chronic deep vein thrombosis.
- •Participant is pregnant.
