HORIZONS: a study of the impact of a cancer diagnosis and treatment on everyday life in people with diffuse large B-cell lymphoma (DLBCL) and other cancers

Being part of this study does not change what treatment you have. The researchers need people to complete regular questionnaires about their health and wellbeing for research.


Purpose of study

The aim of this study is to find out more about how a cancer diagnosis and treatment affect a person’s health and wellbeing. This research could help improve support services in the future.

There are several groups of people who are invited to take part in this trial. One of these groups includes people with diffuse large B-cell lymphoma (DLBCL). The other groups include people under 50 with breast cancer and those with gynaecological (ovarian, cervical and uterine) cancer.


What is involved

Participants are asked to complete questionnaires about their health and wellbeing:

  • after you are diagnosed but before your treatment starts (baseline measurement)
  • 3 months, 12 months, 18 months and 2 years after baseline measurement
  • once a year for up to 5 years (3, 4 and 5 years after baseline measurement).

The baseline questionnaire is given to you by the research team at your local hospital. The follow up questionnaires are posted to you and you can complete them at home. You are given pre-paid envelopes to return questionnaires to the HORIZONS Coordinating Centre.

The researchers also collect information from your medical records, for example details about your treatment. All information collected about you for this study is kept strictly confidential. The study team can give you more details about how your information is used and how it is kept anonymous (you can’t be identified from it).


Who can enter

Your local hospital research team can advise you whether you are suitable for this study.

Around 3000 people with cancer are needed for this study overall, including 1000 people with lymphoma.

You may be able to enter if:

  • You have a new diagnosis of diffuse large B-cell lymphoma (DLBCL).
  • You are waiting for treatment to start and your treatment is intended to cure your lymphoma.
  • You are able to complete the questionnaires in English.
  • You are 16 or over.

You will not be able to enter if:

  • You have a type of lymphoma other than DLBCL (for inclusion in the non-Hodgkin lymphoma group).
  • Your lymphoma is not a new diagnosis but lymphoma that has got worse or come back.
  • You have previously been treated for your lymphoma.
