Home-based Preoperative Exercise Training for Lung Cancer Patients Undergoing Surgery

Will be 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, the investigators will assess 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).

Will be 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.

Will be assessed using the Hamar plus+ digital hand dynamometer. Measurements will be conducted using the standard position approved by the American Society of Hand Therapists. The standard adjustable handle dynamometer will be set at the second handle position for all patients. The non-tested arm will be resting neutrally and both feet were firmly on the ground, shoulder width apart. Patients will be instructed to grip the handle with maximal strength during 3 seconds and the measurements will be repeated three times for the left and right hand, with 30 seconds rest in-between measurements. The highest value for both hands (in kilograms) will be considered as the output measure to each patient.

Patients will be 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 will start 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 will finish when the patients sit on the chair after the fifth repetition, and the time needed to complete the task will be recorded with a stopwatch to the nearest 0.01 s.

Defined as the number of days patients spend in the hospital after surgery. This will be collected from individual clinical records.

Will be assessed using the Comprehensive Complication Index, that integrates all complications with their respective severities on a continuous scale ranging from 0 (no burden due to complications) to 100 (death as a result of complications).Postoperative complications were scored by severity using the scored by severity using the Clavien-Dindo classification.

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 will be 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 will be 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).

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.
