Listen what Berty de Koning has to say about Dr. Boers-Doets's Approach

"I warmly applaud all research aimed at alleviating the side effects of cancer treatment. 

First-hand experience has taught me that not only the disease itself but its side effects, too, can have a huge impact.

It is regrettable that, as a result, some patients do not complete the treatment as planned. We can’t stay without side effects research!

- Berty de Koning, patient, Leiderdorp, The Netherlands"

Success Stories
 Patients tell about  Dr. Christine's side effect approach


"I suffered calluses my entire life, but the calluses grew exponentially large while on regorafenib. I was not able to walk anymore or enjoy my hobby. Christine explained how to apply the TARGET strategy on the calluses and how I could get rid of them. I followed the strategy and you can see the result: I am still on regorafenib AND can enjoy my hobby again. The TARGET strategy led to hemorrhoid cream. Amazing what hemorrhoid cream on the hand palms and foot soles can do!"


"I developed 90% of the adverse events that can come along with panitumumab. With help of the TARGET strategy I was able to relieve the adverse events within 48 hours every time. Even the nail of this finger was not removed at the emergency room because it was treated effectively with vinegar bathes supported with antibiotics. 

Simple, effective, and fast!"


"My mother was diagnosed with NSCLC in September 2012 and treated with gefitinib. She wanted to stop treatment due to extremely painful nail folds. 

Through Christine’s simple, but effective measures, resulting from the TARGET strategy, my mother was able to continue treatment for 5 more years!"

"Christine’s experiences, expertise & assistance provided me with a solid grounding in the evidence guiding the approaches & interventions she described and demonstrated, and practical considerations to enable practitioners to be successful."

Ferdinand Haslbauer, MD

"Her recommendations were a real eye opener!

Despite of several existing guidelines of how to handle these adverse events, Christine´s HHES method (Hit Hard Early & Short) during her lecture, emphasized on correct dosing of different corticosteroids, their equivalence dosages, as well as their anti-inflammatory properties and necessary duration of treatment."

I'm now prepared for 

Future Medications to come 

"August 2018 Christine hold a 2-day course in view of the implementation of an outpatient clinic on adverse event management at our Breast Cancer Unit. Participants were medical oncologists, breast and oncology nurses, pharmacists and patient advocates.

The interdisciplinary training Christine provided was very effective and very much appreciated. She triggered participants to be actively involved. Her systematic adverse event and cancer medication approach is easy to apply in daily practice.

After the training, she was available for online consultation, which allowed us to test what we learned and to continue to be updated.

The method we learned can be easily applied for future medications to come. We will definitely continue to work with CancerMed and we will be ready to recommend her training to other institutions."

“Christine has all my questions about practical matters and about any adverse events with the use of therapy quickly and very knowledgeable answered, so I can properly inform and advise my patients.”
DGKP's Bianca Schedler & Karin Pennetzdorfer Oncology, Salzkammergut Klinikum Vöcklabruck, Austria

"We were most impressed by the way Christine communicates with her patients. Her ASK method has become a fixed part during communications with our patients. Due to the insights, we significantly improved our work!"

Nele Debbaut, oncology nurse medical oncology / radiation-therapy. Ghent University Hospital, Belgium

"Finally, a simplification and the distinction between side effects from chemo- and targeted therapy was a real eye opener. The distinction between mucositis & stomatitis and between hand-foot syndrome and hand-foot skin reaction was enlightening. It actually makes a lot of sense if you look at it that way."

Here is what Professors say about Dr. Christine's scientific work:

“Christine is an enthusiastic and talented practitioner in the area of Supportive Care in Cancer, particularly in the field of Targeted Cancer Therapy. She is doing very important work for the benefit of cancer patients.”

"I know Christine as a very scientific person who is attacked by the vicissitudes of (oncological) patients.

Great partner! "
