The Study
Structured proactive nutritional care delivered via a digital follow-up platform is associated with better postoperative outcomes in gastric cancer patients after radical gastrectomy
This study watched two groups of people after stomach surgery — one group got extra help through a phone app, and the other got the usual check-ins. The app group did better, but we don’t know if it was the app or just because they got more attention and care. So we can say the app group had better results, but not that the app made them better.
Analysis score
Maximum 72 for a cohort study.
Where the score came from
After stomach cancer surgery, patients often lose weight and muscle. This study tested a phone app that gave personalized diet advice and reminded patients to track their food and weight.

Quality score
Groups of people are followed over time to see who develops an outcome. Strong for identifying risk factors and associations, but cannot prove causation as firmly as RCTs.
Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes — keeping muscle and returning to chemo faster can mean better survival and quality of life after cancer surgery.
- 2Patients using the app were 2.2 times more likely to recover from malnutrition (58% vs 34%), had 47% fewer complications, 58% fewer hospital readmissions, returned to chemotherapy 13 days faster, and kept 0.9 kg more muscle than those without the app.

Patients who received structured nutritional care through a digital platform after stomach cancer surgery had a 24 percentage point higher rate of recovery from malnutrition at 12 months than those who received standard care.
After surgery to remove the stomach for gastric cancer, patients who receive structured digital nutritional care have 47% fewer postoperative complications and 58% fewer readmissions due to nutrition problems than those who receive standard care.
Patients who received structured digital nutritional care after stomach cancer surgery returned to their cancer treatment 13 days faster on average and were more likely to start chemotherapy than those who did not receive this care.
After surgery to remove the stomach for gastric cancer, patients who received structured digital nutritional care retained 0.9 kilograms more muscle and 0.9 kilograms more fat-free mass at 12 months than those who received standard care, and their phase angle increased by 0.4 degrees.
Patients who interact more frequently with a digital nutritional follow-up platform after stomach cancer surgery have a higher likelihood of recovering from malnutrition and losing less muscle mass, with each 10-point increase in platform usage corresponding to a 28% higher chance of malnutrition remission.
In patients recovering from radical gastrectomy for gastric cancer, adherence to recommended protein intake explains 36% of the improvement in nutritional status linked to using a digital health platform.
