      Preconditioning before surgery can lower complication rates, but there are significant barriers to its adoption in the lung cancer population, which is characteristically older, suffers multiple comorbidities, and is averse to exercise. In an effort to overcome these barriers, we designed Move For Surgery (MFS), a home-based, preoperative preconditioning program which involves aerobic exercise using wearable technology and deep breathing exercises. We aimed to test the feasibility of MFS in preparation for a randomized controlled clinical trial.


      In this prospective feasibility study, patients undergoing resection for NSCLC were preoperatively enrolled and provided with a wearable activity tracker (Fitbit) and a booklet describing various aerobic exercises, deep breathing exercises, and nutritional and smoking cessation tips. The daily step count, sleep cycle, and calories burned were synced and tracked remotely. Daily step goals were set by increasing the participants’ baseline step count by 600 steps each week until the day of surgery. Participants were encouraged and motivated to reach their daily step goal by daily automatic reminders through the Fitbit. Participants completed the EQ-5D-5L health-related quality of life instrument at baseline and on the day of surgery. Data is presented as mean +/- SD and median (range). Continuous variables were compared using Student’s t-test, and categorical variables were compared using Chi-square or Fischer’s exact test, with a level of significance p<0.05.


      Of the 40 patients screened, 62.5% (25/40) were eligible and enrolled. Of the 15 not eligible, 80% (12/15) did not have a smartphone. Participants (n=25) were enrolled from 11/2017 to 07/2018. Median age was 62 (33-82) and 72% (18/25) were women. The mean predicted FEV1 and DLCO were 88.9% +/- 23.4% and 74.9% +/- 19.8% respectively. Participants spent a median of 25 days (8-55) on trial, and wore their Fitbits 90.0% +/- 25.2% of the time. The mean baseline daily step count for this cohort was 7,586 +/- 4,082, and the participants were able to achieve the daily step goal in 40.8% +/- 30.0% of the time. Participants with higher baseline step counts (≥6,000/day) were more likely to achieve the daily step goals (52.2% vs 20.5%; p=0.0083). Significant improvement was seen in the overall health component of the EQ-5D-5L from before the intervention (76.4 +/- 15.45) to after the intervention (80.4 +/- 14.57; p=0.03). Overall, 96.0% (24/25) of the participants completed the recommended deep breathing exercises, 100% (25/25) recommended MFS for future patients, and 96.0% (24/25) stated they will buy their own Fitbits and continue this lifestyle post-surgery.


      A preoperative preconditioning trial with wearable technology prior to lung cancer resection is feasible based on encouraging enrollment rates, use of the device, and goal achievement, but it is only applicable to participants with smart devices. MFS motivates patients to undergo preconditioning before lung cancer resection and to continue with a healthy lifestyle after surgery. A revision of the daily step goal is required to improve compliance. A randomized trial is in progress to determine the impact of MFS on postoperative outcomes in the thoracic surgery population.
