Feasibility of a Short Home-based Rehabilitation Program for Cancer Patients Waiting for Lung Resection Surgery

Being the leading cause of death from cancer, lung cancer represents a pressing health issue
which generates significant social costs. In Canada, in 2009, an estimated 23 400 people
will be diagnosed with lung cancer, and 20 500 will die from the disease. For people with
localized non small cell lung cancer (NSCLC), lung resection surgery offers the best chance
of curing the disease. In addition with lung cancer, these patients often experience such
effects as a reduction in their exercise capacity and tolerance, muscle weakness, and
decreased quality of life. Many researches demonstrated a link between a low exercise
capacity and cardiopulmonary complications surrounding surgery. Therefore, the
implementation of a preoperative pulmonary rehabilitation program, focused on improving
aerobic capacity, could have significant positive outcomes, notably by reducing operative
risks. The effectiveness of pulmonary rehabilitation, whether carried-out in a supervised
setting or as a home-based program, is well recognized and such programs are included in
guidelines for many pulmonary diseases. Despite these facts, few researches have studied its
impact on lung cancer patients waiting for surgery. Moreover, not one have examined the
feasibility and effectiveness of a home-based program for this population.

We plan to use that time waiting for surgery to increase exercise capacity and work
tolerance of cancer patients waiting for surgery. Our expertise in pulmonary rehabilitation
will prove to be invaluable to carry out this research project which objectives are to
verify the feasibility of a short home-based rehabilitation program for cancer patients
waiting for lung resection surgery, and to measure its effects on aerobic capacity, work
tolerance and muscle strength.

In this way, we hope to contribute in developing innovative interventions that will assist
the Canadian Lung Association's mission of improving the health of patients with respiratory
problems. The results of this study will lead toward the development of a multicenter,
randomized study that will be designed to verify the impact of such interventions on
postoperative complications in this population.

Experimental design:

This pilot study will take place at the research center of the Institut de cardiologie et de
pneumologie de Qu├ębec (IUCPQ), in collaboration with the thoracic surgery division and the
Pavillon de Prevention des Maladies Cardiaques (PPMC). Once the lung cancer and surgical
procedure considered by pneumologist, we will obtain the patient's consent and we will
proceed to the initial assessment.

After the initial evaluation participants will undergo a 4-week home-based rehabilitation
program under the supervision of an exercise specialist certified by the American College of
Sport Medicine. Patients will be reevaluated after 4 weeks.

Preliminary screening: An initial screening, including maximal oxygen consumption
assessment, will be performed under the supervision of a respiratory physician (Dr F.
Maltais) to ensure that patients meet the all the inclusion and exclusion criteria of the
study. In addition, a brief history of each patient's disease course and medication will be

Anthropometric measurements: Weight and height will be measured to determine the Body Mass
Index (BMI). Body composition will be analyzed by bio-impedance (InBody 520, Biospace).

Quality of life and psychological distress: Generic quality-of-life questionnaires provide
information on many aspects of a patient's life and can also be used to discriminate between
patients within the same population. However, they are not as responsive to change as
disease-specific questionnaires. Thus, generic quality-of-life assessment will be obtained
at the time of enrolment. The SF-36 survey was selected for its ease of administration and
because it is the most largely used questionnaire. A French version of the SF-36 is
currently available. These data will be obtained only for descriptive analyses.

Pulmonary function tests: Standard pulmonary function tests including spirometry, lung
volumes, and carbon monoxide diffusion capacity will be obtained for all subjects during the
initial evaluation, according to previously described guidelines, and related to appropriate
reference values.

Incremental cycle exercise test: In order to determine peak aerobic capacity and
eligibility, and to quantify changes in exercise tolerance occurring with exercise training,
an incremental exercise test will be performed (before inclusion). Patients will be seated
on an electrically braked ergocycle (Quinton Corival 400; A-H Robins, Seattle, WA) and
connected to the exercise circuit through a mouthpiece (Sensor Medics, Vpeak Legacy, Yorba
Linda, CA). A progressive stepwise exercise test will be performed up to individual's
peakimum capacity, using exercise steps of 1 minute and increments of 5-10 watts. Heart rate
and oxygen saturation will be recorded using pulse oximetry and ECG, respectively. Symptoms
of dyspnea and leg fatigue will be recorded using a modified Borg scale for perceived
exertion52. Testing will take place under medical supervision, in the exercise physiology
laboratory of IUCPQ research center.

Constant workrate cycle exercise test and 6-min walking test: A constant workrate cycle
exercise test and a 6-min walking test will be performed to quantify changes in exercise
tolerance occurring with exercise training.

1. During the constant workrate cycle exercise test, patients will be asked to pedal at
80% max exercise work rate determined during the maximal test, and the time to
exhaustion will be measured. Heart rate, dyspnea Borg score, and oxygen saturation will
be monitored. Supplemental oxygen will be used if oxygen saturation < 90%.

2. For the 6-min walking test, patients will also be asked to walk as far as possible for
6 minutes with standardized encouragement53. Two trials will be done and only the best
one will be used for data analysis. Monitoring of respiratory and cardiac parameters,
in addition to dyspnea and leg fatigue (modified Borg scale) will be done during the

Strength evaluation:

1. Quadriceps strength will be assessed in two ways. First, by maximum voluntary
contraction, and second, by measuring supramaximal twitch tension from a series of
twitch following a magnetic stimulation (Magstim 200; Magstim Co.) of the femoral nerve
as previously described. Generated force will be measured by an isometric force gauge
while subjects will be in a standardized positioning. Validity and sensitivity of this
equipment have previously been studied and we have used it in previous studies.

2. Maximum voluntary contraction of the biceps brachii, deltoid and hamstring will be
measured with a hand-held dynamometer (Microfet. Hoggan Inc, USA), using the method
described and validated by Andrews and colleagues56. Finally, a maximum prehension
strength will be assessed with a hydraulic dynamometer (Jamar).

Inclusion Criteria:

- Suffering from a non-small cell lung cancer on a waiting list for lung

- Having a VO2 Peak value of less than 20mL/kg/min.

Exclusion Criteria:

- SaO2 less less than 80% during the cardiopulmonary exercise test

musculoskeletal concerns that might limit the ability of these subjects to perform
active exercises

- Severe psychiatric illness compromising training rehabilitation observance
