Patient-Reported Outcomes of Video-Assisted Thoracoscopic Surgery Versus Thoracotomy for Locally Advanced Lung Cancer: A Longitudinal Cohort Study

Abstract

Background: The effects of video-assisted thoracoscopic surgery (VATS) and traditional thoracotomy with respect to patient-reported outcomes (PROs) have only been assessed for early-stage lung cancer. This study was a longitudinal PRO assessment to compare the effects of these surgeries for locally advanced (stage II and III) lung cancer from the patients' perspective.

Methods: We investigated lung cancer patients from a previous prospective, multicentre study. Longitudinal data of clinical characteristics and PROs were collected. PROs were obtained preoperatively, daily in the hospital postoperatively, and weekly up to 4 weeks after discharge or the beginning of postoperative adjuvant therapy. Symptoms and impact on daily functioning and quality of life (QOL) were assessed by using the MD Anderson Symptom Inventory for lung cancer and a single-item QOL scale. Trajectories of PROs over the investigation period were compared.

Results: Overall, 117 primary lung cancer patients (stage II or III), including 63 and 54 patients who underwent VATS and traditional thoracotomy, respectively, were included. During postoperative hospitalization, VATS patients reported milder disturbed sleep (p = 0.048), drowsiness (p = 0.008), and interference with activity (p = 0.001), as well as better work ability (p < 0.0001), walking ability (p < 0.0001), and life enjoyment (p = 0.004). Post-discharge, VATS patients had less distress (p = 0.039), milder pain (p = 0.006), better work ability (p = 0.001), and better QOL (p = 0.047).

Conclusions: Locally advanced lung cancer patients who underwent VATS had lower postoperative symptom burden, less daily function interference, and better QOL than those who underwent thoracotomy.
