A Study to Determine Whether Perioperative Energy Dynamics Correlates With Postoperative Outcomes

Recruiting
Conditions
Pelvic Cancer
Abdominal Cancer
Interventions
Other: Cardiopulmonary Exercise Testing (CPET)
Registration Number
NCT00493688
Lead Sponsor
M.D. Anderson Cancer Center
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:

1. Measure preoperative energy reserve capacity (fitness)

2. 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.

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.

Exclusion Criteria
  • Participant is under age 18.
  • 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.
