Background and objective. Increasing physical activity (PA) is
safe and beneficial in lung cancer (LC) patients. Advanced-stage LC patients are
under-studied and have worse symptoms and quality of life (QoL). We evaluated
the feasibility of monitoring step count in advanced LC as well as potential
correlations between PA and QoL. Methods. This is a
prospective, observational study of 39 consecutive patients with advanced-stage
LC. Daily step count over 1 week (via Fitbit Zip), QoL, dyspnea, and depression
scores were collected. Spearman rank testing was used to assess correlations.
Correlation coefficients (ρ) >0.3 or <−0.3 (more and less correlated,
respectively) were considered potentially clinically significant.
Results. Most (83%) of the patients were interested in
participating, and 67% of those enrolled were adherent with the device. Of those
using the device (n = 30), the average daily step count was 4877 (range = 504-12
118) steps/d. Higher average daily step count correlated with higher QoL (ρ =
0.46), physical (ρ = 0.61), role (ρ = 0.48), and emotional functioning (ρ =
0.40) scores as well as lower depression (ρ = −0.40), dyspnea (ρ = −0.54), and
pain (ρ = −0.37) scores. Conclusion. Remote PA monitoring
(Fitbit Zip) is feasible in advanced-stage LC patients. Interest in
participating in this PA study was high with comparable adherence to other PA
studies. In those utilizing the device, higher step count correlates with higher
QoL as well as lower dyspnea, pain, and depression scores. PA monitoring with
wearable devices in advanced-stage LC deserves further study.
