Understanding the Post-Surgical Non-Small Cell Lung Cancer Patient's Symptom Experience

Persons with non-small cell lung cancer (NSCLC) report significantly more unmet supportive care needs than other cancer populations, yet they are among the most vulnerable and least studied. Two of the most prevalent unmet supportive care needs include overcoming fatigue and attaining adequate exercise to meet physical demands of daily living. Cancer-related fatigue (CRF) is a prevalent, persistent, and distressing symptom in the NSCLC population. Cancer-related fatigue correlates with greater severity of 15 other symptoms, leading to lower physical function for persons with NSCLC. Among 13 core symptoms across 3,106 breast, colorectal, prostate, and lung cancer patients, persons with lung cancer were the most symptomatic, with moderate to severe fatigue being reported with the greatest prevalence. While surgery is the standard curative treatment for NSCLC, no formal guidelines exist for post-surgical rehabilitation. This is a proposed randomized controlled trial (RCT) of a novel rehabilitative intervention for persons with NSCLC after surgery. The intervention promotes self-management of CRF and tests the intervention's impact on CRF severity and fatigability with analysis by age. A previous study incorporating the proposed intervention exceeded goals for recruitment, retention, adherence, acceptability, and preliminary efficacy, with no adverse events reported. The investigator's long-term goal is to develop interventions to increase perceived self-efficacy for CRF self-management in order to improve CRF, symptom status, functional status, and quality of life (QOL) for persons with NSCLC. The objective in this application is to determine the efficacy, optimal timing, and sustainability of this innovative home-based exercise intervention. This study has the potential to transform the current standard by providing a rehabilitative exercise intervention after surgery. The intervention is home-based, self-paced, and builds in duration upon discharge from the hospital after surgery. Aim 1: Determine efficacy by comparing the immediate intervention group with wait-list control (usual care) and attention control by age. Aim 2: Determine efficacy of initiating the exercise intervention 6 wks post-discharge and compare results with the immediate intervention group for all ages. Aim 3: Determine the immediate intervention's sustainability by analyzing 3a) rates of extension, adherence, and retention; 3b) acceptability; and 3c) efficacy of primary and secondary outcomes. IMPACT: The results of this study will provide a novel exercise intervention, and its optimal timing, and fill the gap for a vulnerable population by providing a practical, portable, and low-cost means of reducing CRF severity and fatigability that is enjoyable and applicable to nearly all post-thoracotomy lung cancer patients.
