Supportive Care Intervention (ROAR-LCT) for Patients With Stage IIIA, IIIB, and IV Lung Cancer, ROAR-LCT Trial

Study adherence will be defined as the completion of 70% of the program sessions, repeated assessments, and collection of biospecimens either at the end of the study period or death, whichever occurs first.

Retention rates will be defined as the percentage of participants not lost to follow-up at 1.5 months,

Retention rates will be defined as the percentage of participants not lost to follow-up at 3 months

Retention rates will be defined as the percentage of participants not lost to follow-up at 6 months

A joint model using group-based trajectory modeling will be used to estimate clinically distinct trajectories of functional status and attrition probability (death or dropout). These models will be used to evaluate differences in change of functional scores between study arms through 3 months of follow-up. Additionally, generalized linear mixed models (GLMMs) will be used to model change in functional status from baseline to 3 months to explore if the intervention has both an immediate and sustained impact on function.

Functional Status Assessment: This is a 16-item questionnaire that includes seven Activities of Daily Living (ADL) measures, 5 Instrumental Activities of Daily Living (IADL) measures, and 3 mobility activities. For each activity, disability is defined as the need for personal assistance or inability to perform the activity. Activities are scored as 0 being no help, 1 being with help, and 2 meaning unable to perform the activity. Higher scores indicate greater disability or a lower functional status.

Toxicity assessment completed at the end of each chemotherapy or immunotherapy treatment cycle using the CTCAE V5; (irAEs, AEs, SAEs) Toxicities will be graded 1-5 with grade 5 being the worst and grade 1 being less severe.

GAD-7; This assessment is a 7 item questionnaire that asks patients how often in the past 2 weeks, have they been bothered by each symptom. The responses are scored as 0 being "not at all," 1 being "several days," 2 being "more than half the days", and 3 being "nearly every day," for an aggregate score of 21. Higher scores indicate a higher prevalence of anxiety and are strongly associated with multiple domains of functional impairment and disability days.33

PHQ-9; This is a 9-item depression segment which assesses the severity of depressive symptoms within the last two weeks. Patients will complete the PHQ-9 approximately every 6 weeks administered by the CRC. Items are scored from 0-3 with higher scores indicating greater levels of depression. If 5 or more of the 9 symptoms have been present for "more than half the days," then major depression is indicated. Other depression is indicated if 2, 3, or 4 of the symptoms have been present at least "more than half the days" in the past 2 weeks, and 1 of the symptoms is depressed mood or anhedonia.

Short Physical Performance Battery (SPPB);. The SPPB is a validated tool used to assess lower extremity functioning. It is comprised of three objective measures testing for standing balance, normal gait speed, and strength performance by use of a timed sit-to-stand. The participants are asked to stand with their feet side by side, semi tandem, and tandem for 10 seconds each to assess balance. Normal gait speed is tested by asking participants to walk 8 feet at his or her normal speed. Strength performance is tested by asking participants to complete five timed chair sit to stands without the use of hands. These three measures are scored individually from 0 to 4 with an aggregate score ranging from 0 to 12, with higher scores correlating with a greater functional status. The scores are then classified into 4 categories; very low physical function (0-3); low physical function (4-6); moderate physical function (7-9); and high physical function (10-12).

2-6 min walk test; This is a validated tool used to assess endurance and overall functional exercise capacity. Patients are instructed to walk on a treadmill at their own pace for as long as they are able. At the end of the allotted time, patients are told to stop and the total distance covered is recorded. Participants walking less than 300 meters are considered to have low endurance while those walking over 300 meters are considered to have normal endurance.
