Pre-Operative ERAS® (Enhanced Recovery After Surgery): Randomized Feasibility Trial of Implementing Individualized Prehabilitation for People Undergoing Neo-Adjuvant Radiotherapy and Lower Limb Soft-Tissue Sarcoma Surgery
Summary
This clinical trial evaluates whether patients with deep soft tissue sarcomas who receive a tailored prehabilitation exercise regimen during standard radiotherapy and prior to standard of care surgery have better recovery and surgical outcomes than those who do not. Patients undergoing surgery to soft tissue sarcomas are at high risk for post-operative disability, which is associated with high rates of depression and poor health-related quality of life. Prehabilitation is the practice of exercising before surgery to ensure that the patient is in the best possible condition. It allows patients to prepare their bodies for recovery after surgery, which may result in better surgical outcomes, recovery, and quality of life after surgery.
Detailed description
PRIMARY OBJECTIVES: I. To determine if a tailored prehabilitation program focusing on functional optimization of spared limb tissue in two groups of patients with localized, lower extremity soft tissue sarcoma, one with prehabilitation and one with equal attention and informational support, improves functional outcome as measure by the Toronto Extremity Salvage Score (TESS). II. To identify the measures and metrics most responsive to the intervention using the (TESS), Six Minute Walk Test (6MWT), wearable Heel2Toe sensor technology, and daily step count. III. To estimate recruitment, retention, adherence, and acceptability rates. SECONDARY OBJECTIVES: I. To compare changes in quality of life over time as a result of the prehabilitation intervention using the Edmonton Symptom Assessment Scale (ESAS), European Quality of Life Five Dimension Five Level Scale Questionnaire (EQ-5D-5L) (Euroqol Group), the Patient Generated Index (PGI). OUTLINE: Patients are randomized to 1 of 2 arms. ARM I: Patients perform personalized prehabilitation physical therapy exercises twice a day (BID) 5 days per week for 8 weeks while receiving standard of care radiotherapy and prior to standard of care surgery, attend telemedicine visits with a physical therapist once a week for 9 weeks, and receive educational materials. Patients undergo magnetic resonance imaging (MRI) and computed tomography (CT) at week 9. ARM II: Patients receive educational materials and attend a telemedicine visit with a research assistant once a week for 8 weeks while receiving standard of care radiotherapy prior to standard of care surgery. Patients undergo MRI and CT at week 9. After completion of study, patients are followed up at weeks 2, 6, and 12.

Outcome measures
Primary
Feasibility as measured by recruitment, retention, adherence, and acceptability
Univariate descriptive statistics and frequency distributions will be calculated, as appropriate for all variables. Baseline values for demographic, clinical, and outcome variables will be tabulated for the treatment groups.
Time frame: Up to 22 weeks
Efficacy potential
Univariate descriptive statistics and frequency distributions will be calculated, as appropriate for all variables. Baseline values for demographic, clinical, and outcome variables will be tabulated for the treatment groups. Between-group effect sizes will be estimated for continuous outcomes.
Time frame: Up to 22 weeks
Toronto Extremity Salvage Score
This is a self-report measure comprising 30 items (23 for activities of daily living; 7 items for role participation). Will use this measure, completed using observed performance for feasible items and self-report for the remaining items (getting in and out of a car, shopping; driving). Univariate descriptive statistics and frequency distributions will be calculated, as appropriate for all variables. Baseline values for demographic, clinical, and outcome variables will be tabulated for the treatment groups. Between-group effect sizes will be estimated from a mixed model which considers the individual as a cluster with multiple measures per person.
Time frame: At 2, 6, and 12 weeks
Functional walking capacity
Functional walking capacity is defined as walking capacity needed for everyday activities of daily living such as shopping, traveling to and from work, and walking in the workplace or public buildings. The six minute walk test (6MWT) is the gold standard measure for this. The units are distance in meters covered during the test. There is a standardized mobile application for measuring and data comes minute by minute to assess fatigability. Univariate descriptive statistics and frequency distributions will be calculated, as appropriate for all variables.
Time frame: At 2, 6, and 12 weeks
Gait quality
Gait quality will be measured during the 6MWT using a wearable developed by the team, Heel2Toe sensor. The parameters of gait quality will include proportion of steps with as strong a heel strike pre-operatively, as well as distribution of cadence and of angular velocity. Irregular stepping pattern is indicated by lack of heel strike, large variability in cadence, stride length, and angular velocity as indicated by coefficient of variation. Univariate descriptive statistics and frequency distributions will be calculated, as appropriate for all variables.
Time frame: Up to 22 weeks
Daily step count
Daily step count for the duration of the study will be obtained using the native accelerometer/gyroscope and pedometers available on both iPhone and android devices. Will summarize this complex data using benchmarks of 1, 3, 5, 7, 9 (000 steps) based on meaningful physical activity targets. Will measure the time to achieve these targets post-surgery. These will be captured for the 9 week prehabilitation period and the post-surgery recovery period. As indicated, will focus on steps taken outside of the house as "in house" steps tend to be of very low cadence. For step counts, time to reach the benchmarks of 1, 3, 5, 7, 9 (000 steps) will be calculated and presented descriptively. Univariate descriptive statistics and frequency distributions will be calculated, as appropriate for all variables.
