Brief Summary
To explore the feasibility and best methodology for collecting patient-reported outcome measures in patients who have previously been treated for cancer and are living in the community. The investigators are working with primary care research teams, and using an online electronic questionnaire. Although the study is entirely observational, the study offers some of the questions in a random order, so the investigators can explore the effect of changing the way in which questions are asked.

Outcome Measures
Primary Outcomes (2)
Completion of study questionnaire
Proportion of patients completing the entire study questionnaire
12 months
Agreement to link to national cancer data
Proportion of patients agreeing to link their data to national cancer data
12 months
Secondary Outcomes (4)
Completion of PROMs questionnaires
12 months
Satisfaction with questionnaires
12 months
Effectiveness of different communication channels for recruitment
12 months
Correlation of each PROM score with quality of life
12 months
Other Outcomes (1)
The feasibility of developing a national longitudinal cohort
12 months
Study Arms (4)
Linked to national data
Patients will be randomly assigned to be asked to link personal data with national cancer data. The outcome measure will be the proportion of completed questionnaires
Linking to national data, early vs. late questions
Subset of cohort 1: Patients will be randomly assigned to be asked the question about data linkage at the beginning vs. end of the questionnaire The outcome measure will be the proportion answering yes in each arm
Different PROM Completion rate
Patients will be randomised to two different PROM questionnaires The outcome measure will be the completion rate of the two different questionnaires
Impact of additional PROMS on completion and satisfaction
Patients will be randomised to either a standard PROM or additional, symptom directed questionnaire The outcome measure will be the satisfaction rate of patients in each arm
Eligibility Criteria
All adults living with a previous diagnosis of cancer in a defined geographical area (NW London in stage 1; nationally in stage 2)
You may qualify if:
- Participants who self-identify as having previously (time unlimited) received a diagnosis of cancer, based on histological, radiological, or clinical grounds (primary and/or metastatic cancer). Current treatment is not a barrier to participation, but the emphasis is on patients who have completed treatment.
- Participants need to be able to access the secure online platform, using a mobile device or computer.
- Have capacity and be able to provide informed consent via the online platform.
- To be able to understand, read and write English, with or without support from a trusted individual e.g., friends, family, carer.
You may not qualify if:
- Participants recently diagnosed with cancer (less than 12 months ago).
- Participants unable to access secure online platform.
- Participants who do not have sufficiently good understanding of written English to complete the PROMs and are unable to be supported by a trusted individual to complete the questionnaire.
- Participants lacking capacity and unable to give informed consent.

- Will not share
IPD will be shared, where patients give permission, with the national cancer registration service. Future researchers may then access the data via that route.
