PROMIS questionnaires and smartphone mobility tracking after sarcoma surgery

Official title: Patient-Reported Outcomes and Smartphone-Derived Mobility After Bone and Soft Tissue Sarcoma Surgery: A Multicentre Prospective Cohort Study

Run by University of Calgary · NCT07227961 · Data updated 2026-11-12

This project tests whether PROMIS questionnaires together with a new smartphone app can track recovery and mobility in adults undergoing surgery for sarcoma or giant cell tumor of bone.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are English-speaking adults (≥18) with primary or recurrent bone or soft-tissue sarcoma or giant cell tumor located in the pelvis or limbs who are scheduled for operative tumor resection and own a smartphone.

Probably not a fit

Patients with metastatic bone disease, certain excluded tumor types (atypical lipomatous tumor or dermatofibrosarcoma protuberans), those who are pregnant, lack a smartphone, or cannot complete questionnaires are unlikely to benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Adults with bone or soft-tissue sarcoma or giant cell tumor of bone who are scheduled for tumor resection will use a smartphone app to complete PROMIS questionnaires before surgery and at 6 weeks, 12 weeks, 6 months, and 12 months after surgery. The app will also passively collect mobility metrics such as daily step count, stairs climbed, and gait parameters. Researchers will compare PROMIS scores to the passive mobility data to validate PROMIS in this population and to characterize recovery trajectories following different surgical approaches. Enrollment is limited to English-speaking adults with an iPhone or Android device and excludes patients with metastatic bone tumors or certain tumor types, and the project is observational and conducted at centers in Calgary and at Mayo Clinic sites.

Why it matters

Potential benefit: If successful, this approach could offer more precise, patient-centered measures of functional recovery and allow remote monitoring of mobility after sarcoma surgery.

How similar studies have gone: PROMIS has been validated in orthopedic and oncology populations, but its performance specifically in orthopaedic oncology is not well established, and using passive smartphone mobility data in this context is a relatively novel approach with limited prior validation.
