Effect of Smart Phone App-based Human Coaching Program in Gastrectomized Patients

April 9, 2025 updated by: Bang Wool Eom, National Cancer Center, Korea

A Study Evaluating Effect of Smart Phone App-based Human Coaching Program on QOL in Patients Who Underwent Gastrectomy for Stage I Gastric Cancer

This study is a single center, prospective, randomized controlled study. The aim of this study is to evaluate the effect of smart phone app-based human coaching program on QOL in patients who underwent gastrectomy for stage I gastric cancer. The hypothesis of this study is the patients who used smart phone app-based human coaching program for three months after surgery will have better QOL than patients who did not use it. The QOL will be assessed using EORTC QLQ C30 and STO22 at 3 months postoperatively. The secondary endpoints are QOL at 6 months postoperatively, 12 months postoperative, food intake, body composition, and nutritional indicators from blood test.

Detailed Description

< Patient enrollment>

  • 90 patients in each group, a total of 180 patients
  • 1:1 Randomization using permutated mixed block randomization
  • stratified by surgical extent (distal gastrectomy vs. total gastrectomy)
  • using nQuery program and web-based management system
  • Before discharge, patients are informed how to use the smart phone app and registered to the app.
  • Patients use the app after discharge until 3 months postoperatively.

Participant Group / Arm
Intervention / Treatment
Experimental: Smart phone app group
Patients used smart phone app based human coaching program for 3 months postoperatively.
Behavioral: smart phone app based human coaching program

  1. experimental arm

    • 1:1 coaching using smart phone app
    • Patients are provided several articles about postoperative care (symptom management, diet, and exercise) in the app.
    • Patients are encouraged to report their diet diaries and exercise everyday by the coach.
    • Patients can ask to the coach using the app and the coach answer when they check them.
  2. Comparator arm - Patient have consulting with clinical nutritionist at 1 month and 3 months postoperatively.
Active Comparator: Nutritional consultation group
Patients have two consulting with clinical nutritionist at 1 month and 3 months postoperatively.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Eating restriction score (XEatR) at 3 months postoperatively
Time Frame: 3 months postoperatively

Eating resection scale is calcuated according to the following equation.

  1. Add questionnaire items 41,42, 43 and 46 and divide this sum by the number of items (4):

    EatR = (Q41+Q42+Q43+Q46)/4

  2. Carry out a linear transformation to convert to a 1-100 scale:

XEatR = (EatR-1)*100/3

The 4 items are belong to European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ) STO22.

Each item has a value among 1, 2, 3, and 4 according to the answer and the scale score has a value ranging 0 (minimum) to 100 (maximum).

Higher scores mean having more symptom and worse quality of life.
3 months postoperatively
Eating restriction score (XEatR) at 1 month postoperatively
Time Frame: 1 month postoperatively
Eating resection scale is calculated according to the following equation. a. Add questionnaire items 41,42, 43 and 46 and divide this sum by the number of items (4): EatR = (Q41+Q42+Q43+Q46)/4 b. Carry out a linear transformation to convert to a 1-100 scale: XEatR = (EatR-1)*100/3 The 4 items are belong to European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ) STO22. Each item has a value among 1, 2, 3, and 4 according to the answer and the scale score has a value ranging 0 (minimum) to 100 (maximum). Higher scores mean having more symptom and worse quality of life.

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Eating restriction score (XEatR) at 6 months postoperatively
Time Frame: 6 months postoperatively

Eating resection scale is calcuated according to the following equation.

  1. Add questionnaire items 41,42, 43 and 46 and divide this sum by the number of items (4):

    EatR = (Q41+Q42+Q43+Q46)/4

  2. Carry out a linear transformation to convert to a 1-100 scale:

XEatR = (EatR-1)*100/3

The 4 items are belong to European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ) STO22.

Higher scores mean having more symptom and worse quality of life.
6 months postoperatively
Eating restriction score (XEatR) at 12 months postoperatively
Time Frame: 12 months postoperatively

Eating resection scale is calcuated according to the following equation.

  1. Add questionnaire items 41,42, 43 and 46 and divide this sum by the number of items (4):

    EatR = (Q41+Q42+Q43+Q46)/4

  2. Carry out a linear transformation to convert to a 1-100 scale:
