Brief Summary
Survivors of non-Hodgkin lymphoma and a control group will be screened for (sub)clinical cardiovascular disease, to assess the influence of contemporary treatments on risk and burden of (sub)clinical cardiovascular disease and their influence on survival.

Study Arms (2)
Survivors
Over the past years, a Dutch multicentre hospital-based patient cohort of 5-year non-Hodgkin lymphoma survivors has been established. Survivors will be invited for the current study by their treating physician through the BETER survivorship clinics, or when patients have been dismissed from clinical follow-up, by their former treating physician (or head of the medical department, if the treating physician is retired) within each BETER clinic.
Siblings
As there are no patients who are unexposed to potential cardiotoxic treatment in the BETER cohort we will request every participating NHL survivor to approach one of their siblings, more specifically the sibling who is closest in birthdate to the birthdate of the survivor, for participation in the study.
Interventions
A cardiovascular assessment will be performed to screen for (sub)clinical cardiovascular diseases and to compare the prevalences in survivors of non-Hodgkin lymphoma and a control group.
Eligibility Criteria
* Survivors: Over the past years, a Dutch multicentre hospital-based patient cohort of 5-year non-Hodgkin lymphoma survivors has been established. Survivors will be invited for the current study by their treating physician through the BETER survivorship clinics, or when patients have been dismissed from clinical follow-up, by their former treating physician (or head of the medical department, if the treating physician is retired) within each BETER clinic. * Siblings: As there are no patients who are unexposed to potential cardiotoxic treatment in the BETER cohort we will request every participating NHL survivor to approach one of their siblings, more specifically the sibling who is closest in birthdate to the birthdate of the survivor, for participation in the study.
You may qualify if:
- year survivors from the patient cohort with (mediastinal) large B-cell non-Hodgkin lymphoma (ICD-code 9679) or diffuse large B-cell non-Hodgkin lymphoma (ICD-code 9684), treated with R-CHOP:
- survivors treated between five to ten years ago (2007-2012)
- survivors treated between ten to fifteen years ago (2002-2007)
- Treated in one of the following centers: AVL, Amsterdam UMC (location VUmc or AMC), LUMC, EMC, UMCU, UMCG, UMC Radboud.
- Age at diagnosis 15 up to 60 years.
You may not qualify if:
- Use of immunosuppressant and/or prednisolone
- HIV-infected individuals
- Pregnant women
- Mental disability or psychological condition potentially hampering compliance with the study protocol
- Insufficient understanding of the Dutch language
- siblings of the above mentioned patients (maximum of 1 sibling per patient) with their date of birth closest to the birthdate of the survivor.
- Use of immunosuppressant and/or prednisolone
- HIV-infected individuals
- Pregnant women
- Mental disability or psychological condition potentially hampering compliance with the study protocol
- Insufficient understanding of the Dutch language
