When you are a patient with us, we collect and store personal and medical data, as well as bodily material, for your treatment. This includes, for example, scans, blood, urine, or tissue. We would also like to utilize some data, images, and bodily materials for scientific research into cancer and related disorders, to improve care. This is called “further use”. No additional data or bodily materials need to be collected for this purpose, and no additional action is required. For further use, previously collected materials are used only with your prior consent.
This page tells you more about this consent, about scientific research, and why it is so important. We advise you to read this page carefully.
When you register at the NKI, we ask you to indicate whether you consent to the use of your data for scientific research. Your decision will be recorded in your patient file.
If you do not give consent, we may still ask you to participate in other specific studies. This may involve, for example, completion of a questionnaire or participation in clinical studies (trials). For these, we will always ask for your consent separately.
Why has the NKI introduced this consent question?
Patients increasingly desire to be better informed about the use of their data and materials. The NKI therefore wants to offer transparency towards its patients and has been working on this for several years. Part of this is actively asking patients to participate and consent to scientific research. In addition, the General Data Protection Regulation (GDPR) has provided impetus.
We also follow the Medical Treatment Agreement Act (WGBO). The WGBO deals with the relationship between the patient and the healthcare provider. We also follow COREON's Code of Conduct for Health Research. This contains guidelines for scientific research with bodily material and medical data collected for diagnostics and treatment.
Why is it important that you give consent?
When you give us permission, you help us achieve our goal of eliminating cancer from the world. This is because scientific research teaches us more about how to prevent, treat and cure cancer and related conditions and how to improve our care. In addition, scientific research gives us more insight into how to improve quality of life. This is important for all current and future patients.
Improving quality of life
Why do we request your consent?
Play videoWhat kind of research do we do?
We do different types of scientific research on cancer, including genetic research. We often do this together with other researchers, both in the Netherlands and abroad. We want to understand and treat cancer and related disorders better and better. We also want to continue to improve the quality of life for patients. Therefore, we also conduct scientific research into treatment and patient care. We use various research techniques.
Important results of scientific research are published in scientific journals. You cannot be identified in these.
Frequently asked questions
Please note! A new version of this FAQ is now available. Find the changes compared to the previous version at the bottom of this page.
What kind of research does the NKI conduct with your data and bodily material
When consent is given, is the NKI permitted to do everything it wants with medical data and bodily material?alles doen met mijn medische gegevens en het lichaamsmateriaal?
No. Proposals for scientific research are reviewed. Two points are paramount:
- The patient must continue to be provided with the best care possible for him/her. Research must not get in the way of that.
- In addition, the research must be useful in relation to the patient's condition.
A review board reviews the research: IRB (Institutional Review Board) or the METC (Medical Ethical Review Board). It is possible that this is an external review board, which reviews in a similar way as the review board at the AVL. We make very specific agreements about this.
What does the NKI want with my data and material?
- We use it to conduct scientific research on cancer and related diseases: how can we prevent, treat and cure them? And how can we improve patient care?
- We collaborate a lot with scientific researchers at other institutions and with researchers at companies. Sometimes these researchers are from abroad. This collaboration ensures even better research results. When we collaborate with other researchers, we also want to share your data and materials with them.
- We want to share your data with agencies and organisations that record medical and other data such as:
- The Central Bureau of Statistics’ (CBS) causes of death registry.
- The Dutch Cancer Registry (NCR). NCR may also share the data with scientific researchers at other institutes. This data is coded, so the data is not directly traceable to you.
- Palga. Palga is an encrypted central archive of information about stored bodily material in the Netherlands. The bodily material itself remains at the Antoni van Leeuwenhoek. Palga can share the encrypted data with scientific researchers.
- Hartwig Medical Foundation (HMF). From a small proportion of our patients, HMF is imaging the genetics of the tumor. If this also happens to you, the doctor will let you know. If you give permission, HMF may also share this data with scientific researchers. They do this only if a review board has approved it.
- Very occasionally, a researcher may come across something that could be important to your health or the health of your family members. In that case, the doctor or family doctor will inform you.
What kind of research does the NKI conduct with medical data and bodily material of patients?
- We have been investigating whether we can find new features in tumors that can predict the outcome of treatment. That way, doctors can make a better choice for the best treatment together with the patient.
- We have done scientific research on new and better ways of radiation therapy. With better radiation, we are able to treat the tumor better and damage less healthy tissue.
- We have studied the effects that cancer treatment can have on patients' quality of life. With this knowledge, we can better guide cancer patients and their loved ones during and after the disease.
- We have researched why certain treatments work for some patients and not so well for others. What genetic changes cause these differences? We use this knowledge to develop new treatments.
- We have investigated why a treatment does not work or works less well for some patients after a while and how we can prevent this.
- We have studied how we can continually improve patient care. Small improvements often have a big effect on the care we provide to patients.
- We researched the immune system. How can we use this system to defend the body against cancer? The latest immunotherapy treatments have been created with this knowledge.
Does the NKI make a profit from the research?
No. We do not make a profit from scientific research. Nor do we resell your data and materials to companies looking to make a profit. Do we receive money for a study? Then we use it for patient care or new scientific research.
Protection of your medical data
How does the NKI protect my medical data?
- We value your privacy and we handle your data very carefully. Below you can read how we do that.
- We comply with the rules and laws related to data processing (such as the General Data Protection Regulation (GDPR)) and data security. We also adhere to the agreements for scientific research between doctors, researchers and patient associations. These agreements are in COREON's COREON's Code of Conduct for Health Research.
- We store your data electronically in your patient file. We do this securely. Only authorized personnel have access to your file.
- Do we need data from your patient record for scientific research? Then we work as much as possible with coded data so that you cannot be identified by the researcher. A review board assesses research involving patient data and/or bodily material in advance.
- Do we collaborate with researchers outside the EU? Then we share your data only if they handle your data as securely as researchers within the EU.
- Before we share your data and materials with other researchers, we make written agreements with them about this. Every time.
- Is a researcher writing an article about the results of a scientific study and has that researcher used data or materials from you? If so, readers of the article will not know that the data are yours.
Our privacy statement tells you more about how we handle your data and materials. There you can also read what rights you have.
Who can access my data?
- We store your information electronically in your patient record. We do this in a secure manner. Only authorized personnel have access to your file, and they must sign a confidentiality agreement to do so.
- Do researchers need data from your patient file for scientific research? Then we work as much as possible with coded data so that you cannot be identified by the researcher.
- A review committee assesses research involving patient data and/or bodily material in advance.
Can insurance companies access my data?
- No, only if we are required to do so by law will we provide your personal data to regulators or other competent authorities.
- Your data will not be used for insurance premium review, by insurance doctors or occupational health physicians.
What happens to patient data and material after someone passes away?
Even after a patient has died, we fully adhere to the rules and laws related to data processing and data security with respect to the data and bodily material.
Overview of changes
Added further clarifications on which review committee can assess the research (November 2025).
