Randomized Phase II Study to Evaluate Efficacy of Web-based Patient-reported Outcome (PRO) Application in Solid Cancer Patients

The intervention lasted 12 weeks. Patients in the Mobile PRO group received instruction on symptom reporting and were asked to submit reports at baseline and at least once before each outpatient visit. Treating oncologist reviewed Mobile PRO entries during clinic visits and used the information in clinical decision-making; no automated alerts or additional staff-based interventions were implemented. Usual-care patients did not use Mobile PRO; symptoms were assessed verbally during routine outpatient visits. AEs in both groups were graded using NCI-CTCAE version 5.0. All patients received chemotherapy according to institutional practice, including guideline-based antiemetic prophylaxis. Survival follow-up was conducted every 3 months after the 12-week intervention.
