What happens in Germany
People often ask me what these treatments actually involve. Here it is.
The clinic
Arcadia Praxisklinik in Bad Emstal, near Kassel. A clinic for integrative medicine and cancer treatment, led by Dr. med. Henning Saupe. Every patient gets an individual treatment plan. I’m still in regular contact with him.
What I did there
Two periods of two weeks as an inpatient, with treatments every day, combined with a low-carbohydrate diet:
- IPT — insulin is used to lower the blood sugar level, after which infusions are given. In my case combined with a reduced dose of chemotherapy (lomustine and Alimta).
- Hydrogen therapy — by inhalation.
- Hyperthermia — targeted raising of the temperature of the tumour tissue.
- PEMF — pulsed electromagnetic field therapy.
- Infusion therapy — with vitamin C, curcumin and methylene blue.
- Taurolidine — by infusion, for five days.
The tests in Düsseldorf
On Dr. Saupe’s advice, my hospital’s laboratory sent tumour tissue from an earlier operation to NextGen Oncology Group in Düsseldorf. There it was tested to see which substances my tumour cells respond to, both chemical and natural. Based on those results, I now take a number of them every day.
What continues alongside
The treatments from Germany continue in a scaled-down form. Every ten days I go to Amsterdam for hyperthermia and a vitamin C infusion. Once a month I go to Gronau, just across the German border, for a curcumin infusion. At home I have my own hydrogen device. On top of that, I follow a strict keto diet and take supplements every day.
During the radiotherapy in 2026 I went to the Centrum voor Hyperthermie in Amsterdam twice a week, to give the radiotherapy an extra boost and to spare healthy cells as much as possible. My oncologist and radiotherapist know about this.
How this relates to my treatment in the Netherlands
This comes on top of my hospital care, not instead of it. My doctors know about everything I do in Germany. They can’t give these treatments themselves: they fall outside the protocol that an academic hospital is bound by.
What they have told me is that they are surprised it stayed stable for so long. This type of brain tumour is aggressive. That I had no trouble from it for a year and a half is not something to take for granted.
What this is and isn’t
This is not a cure, and nobody has promised me anything. These are complementary treatments that fall outside what my insurance covers. I applied for reimbursement from my health insurer and corresponded with them at length. The answer is no, because these treatments are not on their list.
What I want now
After the radiotherapy I’m going back to Arcadia for a new two-week treatment period, at the end of October. Dr. Saupe has drawn up a new treatment plan with a quote.
