# Physical activity and lung cancer screening (PALS): feasibility randomised controlled trial of exercise and physical activity in lung cancer screening

## TL;DR

This study shows that an 8-week exercise program is feasible and safe for lung cancer screening participants, improving their physical activity and quality of life.

## Contribution

The study introduces a semi-supervised exercise program integrated into lung cancer screening, demonstrating its feasibility and safety.

## Key findings

- 75 participants were enrolled with a 67% consent rate, showing strong recruitment feasibility.
- 88% of participants in the exercise group attended over 70% of sessions, indicating high compliance.
- The program was safe, with no adverse events reported during the trial.

## Abstract

There is increasing evidence that screening provides a catalyst for behavioural change. Low physical activity (PA) levels are a potentially modifiable risk factor for developing lung cancer. This study aims to assess the feasibility and safety of a semi-supervised 8-week multi-modal exercise program to improve health-related quality of life and PA levels of participants of lung cancer screening.

Participants without lung cancer from a single Australian International Lung Screen Trial (ILST; NCT02871856) site were invited to this feasibility randomised controlled trial. Enrolled participants were randomised to usual care, written material, or a home-based exercise program (in addition to written material). Assessments occurred at baseline, 9 weeks, and 6 months.

75 participants were enrolled over a 3-month period in 2022 (consent rate of 67%). 43% of participants were female, median age 66 years old (IQR 62, 73). Of the 25 participants randomised to the home-based exercise program, 22 participants (88%) attended > 70% of weekly sessions. 99% (74/75) of study participants attended their 9-week and 6-month follow-up assessments.

This study confirms the feasibility and high compliance of delivering a semi-supervised 8-week multi-modal exercise program to participants of a lung cancer screening program. It was safe, with no adverse events.
