Home-based Exercise Training for Lung Cancer Patients Awaiting Surgery

Defined as the ratio of recruited patients to those who were eligible, expressed as a percentage.

Defined as the ratio of patients who completed the study to those who were recruited, expressed as a percentage

Attendance rate will be defined as the ratio of total completed to planned exercise sessions, expressed as a percentage.

Compliance rate will be defined as the ratio of total completed to planned training volume, expressed as a percentage.

Defined as any unfavorable or unexpected event that occurred as a direct result of exercise training, during or within 24 hours after an exercise session. The severity of adverse events was categorized based on the Common Terminology Criteria for Adverse Events (CTCAE), version 5. The CTCAE provides a grading (severity) scale, with each adverse event been classified as grade 1 (asymptomatic or mild symptoms, clinical or diagnostic observations only, and/or intervention not indicated) to grade 5 (death). An adverse event was classified as "serious" if it resulted in hospitalization, persistent or significant disability, was life threatening, or resulted in death (i.e., grade 3 or higher).

Assessed by the Incremental Shuttle Walk Test (ISWT). The ISWT measures the distance in meters an individual can walk around a 10 meters shuttle course paced according to an incremental speed dictated by an audio recording and was performed under the supervision of a single investigator using the protocol described by Singh et al.

(1992). The test finished when the participant can no longer maintain the desired speed or became too breathless to continue.

Assessed through the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire C30 (QLQ-C30) (version 3.0). The QLQ-C30 is composed of 30 questions, including five multi-item functioning scales, three multi-item symptom scales, six single-item symptom scales, and a two-item global health status scale [GHS]. Scores range from 0 to 100 points, with a higher score on the functioning scales indicating a higher level of functioning, whereas a higher score on the symptom scales indicates a higher level of symptom burden.

In addition, was assessed the EORTC QLQ-C30 summary score (SumSc) because it provides a psychometrically more robust alternative to the GHS score that is frequently used as the primary HRQOL endpoint in clinical trials. The SumSc is calculated from the mean of 13 of the 15 QLQ-C30 scores (the GHS and financial impact scales are excluded).

Assessed using a Jamar hydraulic hand dynamometer (JA Preston Corporation, Jackson, MI, USA). Measurements were conducted using the standard position approved by the American Society of Hand Therapists. The standard adjustable handle dynamometer was set at the second handle position for all patients. The non-tested arm was resting neutrally and both feet were firmly on the ground, shoulder width apart. Patients were instructed to grip the handle with maximal strength during 3 seconds and the measurements were repeated three times for the left and right hand, with 30 seconds rest in-between measurements. The highest value for both hands (in kilograms) was considered as the output measure to each patient.

Patients were instructed to perform the Five Times Sit to Stand Test (5STS) on a standardized armless chair (i.e., seating height between 41-45 cm, no elbow rests and wheels). After the cue "ready, set, go!", patients started the STS repetitions as rapidly as possible from the sitting position with their buttocks touching the chair to the full standing position, with their arms crossed over the chest. The 5STS test finished when the patients sit on the chair after the fifth repetition, and the time needed to complete the task was recorded with a stopwatch to the nearest 0.01 s.
