About this trial
The goal of this clinical trial is to learn whether an app-based, patient-centered prehabilitation program improves preoperative functional capacity in adults scheduled for elective cancer surgery. The main questions it aims to answer are:
Does the program increase the six-minute walk distance (6MWD) measured on the preoperative day (within 24-48 hours before surgery)?
Compared with usual care, does the program improve preoperative adherence to home 6MWT practice and patient-reported anxiety/depression (HADS)?
Researchers will compare an app-based prehabilitation program to usual care to see if the program improves preoperative functional capacity.
Participants will:
Use a study app to perform weekly home six-minute walk tests (6MWT) and complete brief daily check-ins (exercise, nutrition, psychological status) before surgery.
Attend routine preoperative admission (no extra visit) for in-hospital 6MWT (primary endpoint) and brief assessments (grip strength, Timed Up \& Go, HADS, skeletal muscle mass by InBody where available/fee-free).
Attend one routine postoperative outpatient visit at 3 or 6 months (site-standard timing) for follow-up assessments.
No additional study-specific clinic visits are required outside usual care.
Eligibility criteria
Qualifiers
Adults ≥18 years.
Elective cancer surgery planned under general anesthesia at a participating site (e.g., gastrointestinal, hepatobiliary-pancreatic, thoracic, gynecologic, or other site-approved cancer operations).
Ambulatory: able to walk independently (assistive device such as a cane is allowed) and deemed safe to perform a six-minute walk test (6MWT) per investigator judgment.
Smartphone access and app use: owns/has regular access to a smartphone capable of running the study app and agrees to use the app (notifications, weekly home 6MWT logging, brief daily check-ins).
Disqualifiers
Emergency surgery or surgery date that cannot accommodate even minimal prehabilitation onboarding.
ASA IV or higher, or any unstable/critical condition that, in the investigator's opinion, makes participation unsafe.
Contraindications to 6MWT/light walking, including but not limited to: unstable angina, recent myocardial infarction (≤30 days), decompensated heart failure, uncontrolled clinically significant arrhythmia, severe symptomatic aortic stenosis, severe uncontrolled pulmonary disease, or investigator-judged safety concerns (e.g., resting severe hypoxemia, high fall risk).
Non-ambulatory status or musculoskeletal/neurologic conditions that preclude performing a 6MWT.
