Understand and choose your treatment options better.
Know what actually works before you start.
Spare yourself unnecessary suffering and the side effects of ineffective treatments.
A treatment decision is easier when you clearly understand the options under consideration, and the chance of getting the most benefit from them.
For many treatment classes, efficacy and response rates are often below 50%. In practice, that means starting a treatment without knowing whether it works, waiting many weeks to find out, and only then learning it was not the right one. That is time, strength and hope that would have been better kept, and focused on the right treatment.
Many cancer treatments today are chosen based on how well they performed across large groups of patients in clinical trials. That is a reasonable starting point, but your own tumor's actual response may be different. This page explains how a decision can be matched to the biology of your tumor, so the conversation with your oncologist rests on more personal information.
Of 10 patients given the same treatment, often fewer than half respond. The average cannot tell which group you are in. Illustrative
Genomic testing, which reads your tumor's DNA, helps some patients, but it points to a matched therapy for only about one in four people tested. For those who receive a match, the chance of response improves; the rest are still left with considerable uncertainty.
Check your next treatment's statistics here. A tool to help you see the treatments relevant to your case and how they typically perform, so you and your doctor can weigh your options together.
Know before you start
See how your tumor responds biologically to each option under consideration, instead of trying one treatment and waiting weeks for the result.
Spare yourself an ineffective treatment
A treatment that does not work still carries many side effects. Knowing in advance which treatments your tumor is unlikely to respond to can spare weeks of unnecessary suffering, for no benefit.
Several treatments, one sample
Several treatments suited to your situation are tested in parallel on the same tissue, as single drugs or combinations, so your oncologist can compare how they perform.
90%+
High accuracy: in clinical studies, the test predicted the tumor's actual response to drugs, positive or negative, in over 90% of cases.
CE marked to European standards for in-vitro diagnostic devices.
Solid Tumors
Suitable for all solid tumor types.
Broad Drug Coverage
Assesses chemotherapy, biological and targeted therapies, and combinations.

The test ranks the treatment options under consideration. In a published study of 278 patients, the test result added value in one of three ways, each of them useful:
The planned treatment is expected to work
The treatment your oncologist planned showed good efficacy on your tumor, so you can start it with more confidence. Sometimes the test also surfaces other effective options, widening your oncologist's choice, for example to one with fewer side effects.
A better-matched option is found
The planned treatment showed low efficacy on your tumor, and the test points to another option with better efficacy. You can start with the option that showed the strongest response on your tumor, instead of starting an ineffective one and finding out after weeks of side effects.
No tested treatment was found effective
Knowing this in advance spares a great deal of suffering from ineffective treatments, and gives you and your oncologist time to consider other paths, such as a clinical trial or care focused on comfort and quality of life.
| cResponse™ | Genomic testing alone | |
|---|---|---|
| What is tested | Your living tumor cells, exposed to the treatments themselves | The genetic makeup of your tumor |
| A clear treatment direction | A ranked comparison of the options tested on your tumor | A matched therapy for about 1 in 4 patients |
| Link to your actual response | 90%+ accuracy against patient outcomes | A genetic match does not guarantee a response |
| Can it show that no option will work? | Yes, helping avoid a treatment with no real benefit | No, it can only suggest a possible match |
| Time to result | About 14 business days | Often several weeks |
Fresh tumor tissue is taken by biopsy or surgery. Our courier collects it the same day.
The sample reaches the lab, and the list of treatments is received from your oncologist. Optional rapid genomic sequencing may help identify additional drugs to test.
Several possible treatments are tested in parallel on your tissue.
Results are analyzed and a comparative ranking report is prepared.
Your oncologist receives the report and can discuss it with you.
Treatment decisions build on one another, and each choice shapes the treatment options that follow. That is why each one is worth making thoughtfully and based on solid information, rather than by trial and error. This is not about fear; it is about the real value of a well-matched choice, and about your right to understand and take part in it.
The simplest next step is to ask your treating oncologist about cResponse™, and whether functional testing could help with your specific decision.
- “For my cancer and stage of treatment, how many patients actually respond to the recommended treatment?”
- “If this treatment does not work for me, what would my next options be?”
- “Could the possible treatments be tested on my tumor first, so we choose the one expected to be most effective for me?”
cResponse™ may be worth asking about if:
- You've been diagnosed with a solid tumor and are now facing your next treatment decision.
- You and your doctor are weighing between more than one possible treatment.
- You have a tumor from which fresh tissue could be taken by biopsy or surgery.
- You want an additional, functional data point alongside imaging and genomic testing, to support the best decision given the response rates and side effects of current options.
cResponse™ is suitable for solid tumors (not blood cancers) and is performed on fresh tissue, so sample collection needs to be arranged with us in advance. Ask your oncologist whether it's a fit for your specific case.
Will this delay my treatment?
Results are typically ready within 14 business days, a timeframe that's common and accepted at oncology decision junctions.
Is the test itself painful?
It uses a standard biopsy, a common, minimally invasive procedure already used in oncology, or tissue taken during surgery. Note that fresh tissue is required; a previous biopsy sample can't be used for this test.
Does insurance cover it?
Coverage varies. Contact us for current details on what's typically involved.
Is it suitable for every cancer?
cResponse™ is applicable across solid tumor types. It is not suitable for blood cancers. If you're unsure, ask your oncologist to reach out to our team directly.
Who sees my results?
Your results go directly to your ordering physician, who will discuss them with you as part of your care.
