Preoperative Home-based Multimodal Prehabilitation Based on 5G + Artificial Intelligence Mobile Health

The main questions it aims to answer are: Does digital multi‐modal prehabilitation reducethe postoperative comprehensive complication index (CCI) compared to conventional care?Does the intervention improve perioperative functional capacity (e.g., 6‐minute walkdistance, cardiopulmonary function), nutritional status, psychological well‐being,chemotherapy adherence, and long‐term survival outcomes (3‐year overall and disease‐freesurvival)? Researchers will compare the experimental group (receiving at least 2 weeks of5G+AI digitally supervised home‐based multi‐modal prehabilitation plus standard ERASperioperative management) to the control group (receiving conventional management plusstandard ERAS perioperative management) in a 1:1 randomization to see if the digitalprehabilitation approach significantly lowers postoperative complications, enhancesfunctional reserve, improves nutritional and psychological status, and optimizes recoveryand survival.
