Information for general practitioners

You can refer your patients to the NKI for (rapid) diagnostics, second opinions or further treatment. Referrals from general practitioners go through ZorgDomein

We offer rapid diagnostics for many types of cancer. All relevant examinations take place as much as possible in one day. The patient also speaks to all the specialists involved and the patient is discussed within the multidisciplinary team (MDO). In most cases, the patient has a preliminary treatment recommendation on the same day. 

Referral for Radiotherapy

Do you have a referral for the Radiotherapy Department?  Then we ask you to send an e-mail to: RT-medsec@nki.nl and to send the following information:

  • a referral letter containing the relevant medical history
  • copies of relevant pathology reports
  • copies of relevant operation reports
  • copies of relevant X-ray reports

Radiology images and reports can be exchanged digitally via the Twiin image exchange portal.

If it  isurgent, you can call 020 512 9111. The medical data can then be given to the patient.

Sending radiological and nuclear examination images

Determining circulating tumor DNA

The Netherlands Cancer Institute offers referrers the opportunity to request a circulating tumor DNA (ctDNA) analysis. To do this, go to our laboratory forDNA diagnostics. 

Overview of ongoing trials

Some of the trials have a Dutch summary suitable for patients. These are here on the website.

Phase 1 study

If there are no more regular treatment options for your patient, there may still be experimental treatment options in the context of the so-called phase 1 studies. If you want to know if your patient may be eligible for one of our phase 1 studies, you can send a short email to fase1@nki.nl.

If you provide at least the following information in the email, we can assess whether your patient could possibly participate in an experimental treatment in our hospital and whether referral for this is useful. We aim to answer your email within a few days.

Minimal data in mail:

  • Referrer Name
  • Referrer's phone number
  • Patient Name
  • Patient's date of birth
  • Tumor type
  • Previous treatments
  • Known results of molecular diagnostics

NB: Are you a patient and do you want to know if you are eligible to participate in a phase 1 study? Then ask your treating specialist to contact us.

Foto Second Opinion

Second opinion at the NKI

Does your patient need a second opinion on an already made diagnosis or a proposed treatment plan? Or do you want to check whether your patient is eligible to participate in a study? Then you can easily refer your patient to us via ZorgDomein. In ZorgDomein you will find the option for a second opinion under the relevant specialty.
