Early initiated postoperative rehabilitation enhances quality of life in patients with operable lung cancer: Secondary outcomes from a randomized trial.

INTRODUCTION: Patients with lung cancer report a lower degree of Health Related Quality of Life (HRQoL) compared with other cancer patients. HRQoL reflects how patients experience the impact of their disease and its treatment on their quality of daily living. A widely used questionnaire in lung cancer patients is the Functional Assessment of Cancer Therapy - Lung (FACT-L) questionnaire. Here we report the secondary outcomes on FACT-L data from the Postoperative Rehabilitation in Operation for Lung CAncer (PROLUCA) study, which describes the effect of early (14 days) versus late initiated (14 weeks) postoperative rehabilitation. MATERIALS AND METHODS: The PROLUCA study was designed as a two-armed randomized controlled trial with an early rehabilitation group (14 days after surgery (ERG)) or a control arm with a late rehabilitation group (14 weeks after surgery (LRG)). The results for seven domain scores obtained using the FACT-L at the following time-points: baseline, 14 weeks, 26 weeks and 52 weeks after surgery are presented here. RESULTS: 119 patients were randomized to the ERG and 116 to the LRG. In the ERG, HRQoL measured by both FACT-L and FACT-G (general core instrument) showed a continuous improvement up to 26 weeks after which HRQoL decreased after further 26 weeks without structured intervention. In the LRG a non-significant deterioration was detected over the first 14 weeks after surgery. After participation in the 12 weeks rehabilitation program, an increase in HRQoL was seen, without reaching the same level as the early group. CONCLUSION: Analyses of the seven domain scores obtained using FACT-L and FACT-G reflect the importance of starting exercise early after surgery since the ERG avoid a temporary decrease in HRQoL. It is therefore recommended to start up a structured rehabilitation program 14 days after surgery, containing high intensity interval training and strength exercise twice a week for 12 weeks.

Early initiated postoperative rehabilitation reduces fatigue in patients with operable lung cancer: A randomized trial.

INTRODUCTION: Little is known about the optimal amount and timing of exercise strain in concern of the operation wound and with regard improvement of physical function and quality of life (QOL) after surgery for lung cancer. On this background, we decided to investigate the effect of early vs. late initiated postoperative rehabilitation in patients with operable lung cancer on exercise capacity, functional capacity, muscle strength, and QOL. METHODS: The study was designed as a two-armed randomized controlled trial with randomization to either early initiated postoperative rehabilitation (14 days after surgery (ERG)) or a control arm with late initiated postoperative rehabilitation (14 weeks after surgery (LRG)). The primary endpoint was a change in maximum oxygen consumption (VO2peak) from baseline to post intervention 26 weeks following lung resection. Fatigue was measured with EORTC QLQ C30 LC13. RESULTS: From April 2013 to June 2016, 582 patients with operable NSCLC were screened for eligibility. With 119 patients randomized in the early rehabilitation group (ERG) and 116 randomized to late rehabilitation group (LRG). There was no significant difference from baseline to 26 weeks between ERG and LRG (p = 0.926). There was a significant difference from baseline to 14 weeks between groups (p = 0.0018). There was a significant difference from 14 weeks to 26 weeks between the two groups (p < 0.001). We found no significant differences in QOL but we found a significant difference between ERG and LRG from baseline to 14 weeks in fatigue level in favour of ERG. CONCLUSION: This is the first randomized controlled trial to investigate the effects of early vs. late initiated postoperative rehabilitation in patients with lung cancer. There is no difference in the commencement (early vs. late) of a postoperative exercise program for patients with lung cancer on exercise capacity. But to reduce fatigue patients should be recommended to initiate early exercise programs.
