Resiliency among Older Adults Receiving (Roar) Lung Cancer Treatment: A Feasibility Study

ABSTRACT

PURPOSE/HYPOTHESIS: Poor physical performance and negative mood are two risk factors for functional decline among older adults with lung cancer. Yet, targeted interventions to maintain independence prevent functional decline are not well studied. Our primary objective was to assess the feasibility of a novel virtual health physical therapy (PT) plus progressive muscle relaxation (PMR) intervention with longitudinal microbiome biospecimen collection delivered to older adults with advanced lung cancer. Secondary objectives were to characterize functional status and clinical factors pre and post-study intervention. NUMBER OF SUBJECTS: We accrued adults aged >=60 years with advanced non-small cell or extensive-stage small cell lung cancer receiving treatment at The Ohio State University James Comprehensive Cancer Center (OSU-JCCC) in the Thoracic Oncology department (N=22). There were no exclusion criteria pertaining to Eastern Cooperative Oncology Group (ECOG) performance status, laboratory values, prior cancer diagnoses, presence of comorbidities, or brain metastases. MATERIALS AND METHODS: Participants were asked about functional status, symptoms, mood through the PHQ-9, GAD-7, POMS, and acceptability questions about the program. PT evaluation and assessment included SPPB and 2- or 6-minute walk test outcomes. The study sought to collect gut microbiome samples for every in-person visit and activity monitoring data (Actigraph) on a subset. Feasibility was defined as successfully collecting specimens, wearing an Actigraph activity monitor, and adhering to the intervention. PT and psychologists evaluated participants in-person at the first and final visit. The rest of the 12-week intervention was conducted via virtual health. Physical therapy intervention consisted of endurance, strength, and flexibility exercises. RESULT(S) In total, 22 patients consented and 18 started the intervention (81.8%). Seven microbiome samples were collected from four participants. Six patients collected activity monitoring data. Among the 18 participants, 11 participants (61.1%) completed 70% or more of all the intervention visits. The SPPB data show a moderate effect size (Cohen's d=0.24) from pre- to post-data. On average patients improved by 1.8 total points on the SPPB. Patients demonstrated improvement on timed walk tests throughout intervention from an average of 108 feet pre-intervention to an average of 138.4 feet post intervention. CONCLUSION(S) Despite the challenges of the COVID-19 pandemic, longitudinal biospecimen and correlative data collection were feasible in the context of PT and PMR intervention among older adults with advanced lung cancer. Virtual physical therapy interventions can be safely delivered to improve physical performance as demonstrated by a moderate effect size for the SPPB in this patient population. CLINICAL RELEVANCE Based on the feasibility study results, delivering a virtual PT intervention to older patients with lung cancer can improve SPPB score leading to decreased frailty and improve quality of life among patients.
