Patient-Reported Symptom Care Versus Usual Care After Esophageal Cancer Surgery: A Single-Center Phase 3 Randomized Trial

Postoperative esophageal cancer patients will receive a PRO (patient-reported outcome) symptom self-report system via a WeChat mini-program/electronic form. The system covers 12 target symptoms-pain, fever, cough with sputum, dyspnea, palpitations, fatigue and activity limitation, nausea/vomiting, acid reflux/heartburn, abdominal bloating, diarrhea, swallowing obstruction (dysphagia), and hoarseness with coughing when drinking-and uses a five-level severity scale: 0 (none), 1 (mild), 2 (moderate), 3 (severe), and 4 (very severe). If any of the 12 symptom scores entered in the mini-program reaches the predefined intervention threshold (≥2, indicating moderate to very severe), the system sends a real-time alert to the surgeon, who is required to respond within a specified time window. After discharge, interventions are delivered via WeChat, text message, or telephone. Interventions mainly include counseling, patient education, prescription medication.

Patients in the control arm receive conventional postoperative symptom management. The electronic questionnaires use the same content and time points as the intervention arm, but reported symptoms do not trigger alerts, and surgeons cannot view the symptom scores. During the postoperative inpatient stay, surgeons typically assess symptom severity based on patient reports during morning and afternoon rounds and manage symptoms according to the same guidelines and consensus as the intervention arm. After discharge, patients do not receive proactive symptom management from their primary surgeon unless they actively seek medical care.
