Project summary

Although the EORTC QLQ-STO22 is one of the most well-established instruments for measuring the HRQOL of people with gastric cancer, the module is in need of a potential update in order to capture the Health related quality of life (HRQoL) issues related to the new and diverse treatment strategies which have emerged since the development of the original QLQ-STO22 and to include the perspective of patients and health care professionals from East Asia.
This study is conducted within the network of the EORTC QLG, EORTC Gastrointestinal Tract Cancer Group, and the Japan Clinical Oncology Group (JCOG) Stomach Cancer Study Group including different countries of the European Union, UK, China, Mongolia, South Korea and Japan.
1.1.1 The update of the QLQ-STO22 project has two overall objectives:
1) Evaluate the need for an updated QLQ-STO22 to accommodate changes to treatment modalities and to include the perspective of patients and clinicians from East Asia.
2) To develop a provisional draft updated STO22 covering new treatment schedules and the experiences of patients with GC from East Asia thus positioning the STO22 more globally as a standard module to assess HRQOL of GC patients.

In order to identify the HRQOL issues of importance and relevance to people with gastric cancer globally (including East Asia), we will be reviewing the literature and asking patients and health care professionals to share their experiences and opinions. During the first phase, we will invite 60 people with stomach cancer, to comment on the existing QLQ-STO22 to see if the questions are relevant to them and whether anything has been overlooked. We are interested in finding out about all the different ways the effects of stomach cancer and its treatment affect people’s lives. The research will explore the best way to measure the effects of stomach cancer on people’s lives and look at whether the current questionnaire (QLQ-STO22) is suitable. We want to be sure we are capturing issues from people in different countries. We especially want to understand the issues for people in East Asia where people’s experiences have been under reported. After we have carried out our first set of interviews across different centres and countries, we will be in a position to propose any changes to the questionnaire which will subsequently be reviewed for relevance by an additional 30 patients and 15 healthcare professionals.


  • Systematic Review is currently in progress: a main review of health-related quality of life issues of people with gastric cancer has been conducted and is being written up for publication.
  • Ethical permissions have been gained in 8 countries and are or are currently being sought in 4 remaining sites.
  • Active collaboration with sites to initiate set-up: Active sites include those in the UK, Japan, Cyprus, Turkey, Spain, Norway, and Malaysia. Sites currently in set-up include those in India, South Korea, China and Mongolia.
  • Data analysis for patient interviews in under way.


8 sites have finished recruitment for Phase 1a.

4 sites are in set-up for Phase 1a with recruitment to end at the end April 2021 for Phase 1a.

Recruitment for Phase 1b is to start imminently (May 2021)

Future plans

Concluding interviews with patients will be conducted during April 2021 for Phase 1a.  The update questionnaire will be reviewed by patients and healthcare professionals in May-Sept 2021.


We very much welcome new collaborators. Please get in touch with the Project Coordinator, Dr Ali Rowsell: if you want more information about the project or if you would like to join the team of collaborators.

For patients

We are conducting a study which asks adults with stomach cancer to look at a questionnaire to see if the questions and issues are relevant to them. This will help us find out about all the different ways stomach cancer and its treatment affect people’s lives. We want to find the best way to measure the effects of stomach cancer on people’s lives and whether a current questionnaire we have is suitable. We are showing people with stomach cancer a questionnaire which has been developed for people like them and will interview them about the questionnaire. We are interested in their thoughts on the issues in the questionnaire and also on whether they have any suggestions for questions or have experienced any other issues not covered by the questionnaire. We are particularly interested in whether the issues are the same for people in different parts of the world, including East Asia. Therefore, we will be talking to people from many countries. Once we have spoken to people with gastric cancer and reviewed the questionnaire and issues with patients and healthcare professionals, we will update the questionnaire if it needs it.
