What a Precision Oncology Programme — Should Actually Include
A precision oncology programme does more than offer the latest drugs. It uses molecular testing to understand your specific tumour and builds a treatment plan around that — not around the average patient with your cancer type.

- Treatment matched to your biology — Precision oncology uses markers from your tumour tissue, not the cancer name alone, to decide which treatment is most likely to work.
- Testing before prescribing — A complete programme runs biomarker testing — PD-L1, MSI, NGS and others — before settling on a plan, not after other options have failed.
- Board review, not one opinion — Complex decisions are reviewed by a multidisciplinary team including oncologists, pathologists and radiologists before treatment begins.
- Day care where possible — Immunotherapy and most targeted therapies do not require hospital admission. Day-care administration is a marker of programme maturity.

A precision oncology programme uses molecular testing of your tumour tissue to match treatment to its specific biology rather than its type alone. A complete programme includes biomarker testing, a multidisciplinary tumour board, access to targeted therapies and immunotherapy, and coordinated imaging. These components together — not any single one — define the standard.
What does a precision oncology programme offer that standard oncology does not?
| Component | Standard oncology | Precision oncology programme |
|---|---|---|
| Basis for treatment choice | Cancer type and stage | Molecular profile alongside type and stage |
| Testing before treatment | Standard pathology (H&E, basic IHC) | Extended biomarker panel — NGS, PD-L1, MSI, and others as indicated for the cancer type |
| Treatment planning | Protocol based on tumour type | Individual plan reviewed by a multidisciplinary tumour board |
| Systemic therapy setting | Inpatient or day care depending on regimen | Day care as the default for eligible regimens |
| Response imaging | CT scan | PET-CT coordinated with specialist imaging |
| When standard options are exhausted | Referral to another centre | Clinical trial pathways discussed as part of the plan from the start |
How do you tell whether a centre actually does this — or just says it does?
Ask three specific questions. First: does the centre run biomarker testing on tumour tissue before deciding on treatment, and which markers? A centre that cannot name the tests is not running a precision programme.
Second: is there a tumour board — a regular meeting where oncologists, pathologists, radiologists and surgeons review cases together? Ask how often it meets and whether your case will go before it.
Third: are targeted therapies and immunotherapy given as day care, or does treatment require admission? Day-care capability indicates the infrastructure to deliver these regimens safely and routinely.

Did you know?
NCCN and ESMO guidelines now recommend biomarker testing before first-line treatment for several cancers — including lung, colorectal, breast and gastric — because treatment without testing risks giving an ineffective regimen when a better-matched one exists.
Testing changes the treatment decision in a meaningful proportion of patients who would otherwise have received a regimen unlikely to help them.

What should you ask when comparing precision oncology programmes?
Does a smaller centre near home ever make more sense than travelling to a large one?
It depends on the regimen. Chemotherapy given every three weeks, or immunotherapy with straightforward monitoring, can sometimes be delivered closer to home once the plan is established. Complex regimens, first cycles of a new treatment, or cases requiring multidisciplinary input usually benefit from a centre with full infrastructure. Ask your oncologist which parts of your treatment genuinely need the larger centre and which can be delivered closer to home — that is a question they should be able to answer specifically.
What does 'multidisciplinary tumour board' actually mean in practice?
A tumour board is a scheduled meeting where your case is presented to oncologists from different disciplines — medical, surgical, and radiation — alongside a pathologist and a radiologist. The outcome is a consensus recommendation rather than a single doctor's judgement. What you want to know is whether your case will actually be reviewed, not simply whether the board exists. Ask: 'Will my case be presented at the next board meeting, and when will I hear the outcome?' A centre with a functioning board will have a straightforward answer.
We cannot afford extensive molecular testing. Does that mean precision oncology is not for us?
Not necessarily. Some biomarker tests are part of standard care and included in treatment costs in many settings. Others are more expensive and may be discretionary. What matters is knowing which tests are clinically relevant for your cancer type — your oncologist should be able to say which markers are likely to change the treatment plan and which are not. Paying for a broad genomic panel when only one or two markers apply to your cancer type is expensive information with limited practical use, not more precise care.
Does CION run biomarker testing?
Biomarker testing — including PD-L1, MSI, and relevant panel testing — is coordinated as part of treatment planning at CION across its 35+ centres. PET-CT is arranged through partner imaging centres. Immunotherapy is administered as day care. CION does not provide CAR-T or cell therapy; patients for whom those are being considered are referred to appropriate centres. If you want to discuss which tests are relevant for your diagnosis, bring your previous biopsy report and pathology results to the first appointment — that is the starting point.
How do I know if the molecular testing was done properly?
The test report itself should name the laboratory, the methodology used, and the specific markers tested. For sequencing-based tests, it should state the genes or regions covered. If the report is vague — 'molecular testing done' without specifics — ask your oncologist or the centre's coordinator for the full laboratory report. Reputable laboratories issue structured reports that an oncologist can interpret directly. If you are uncertain about the interpretation, a second opinion on the pathology and molecular results is a reasonable request.
Is a second opinion worth getting even if we are satisfied with our current oncologist?
Yes — particularly for complex or rare cancers, cases where a biomarker result is borderline, or where first-line treatment did not work as expected. A second opinion is not a vote of no confidence; it is standard practice in any situation where the decision carries large consequences. Most oncologists at experienced centres will not be discouraged by a request for one. Ask for your records, pathology slides, molecular reports and imaging to be made available — the second-opinion centre will need all of them to give you a meaningful answer.

Frequently asked questions
What is a precision oncology programme?
A precision oncology programme uses molecular or biomarker testing on your tumour tissue to identify the specific characteristics driving your cancer's growth. Treatment is then selected based on those characteristics rather than the cancer type alone. It typically includes extended biomarker testing, review by a multidisciplinary team, and access to targeted therapies and immunotherapy where indicated. Not every patient will have a targetable marker — a complete programme also means being told clearly when standard treatment is the right choice.
What biomarker tests should a precision oncology programme be able to run?
The tests that matter depend on your specific cancer type, so there is no universal list. Commonly relevant markers include PD-L1 expression for immunotherapy eligibility, microsatellite instability for checkpoint inhibitor response, BRCA status for breast and ovarian cancers, EGFR and ALK for lung cancer, and HER2 for breast and gastric cancers, among others. Ask your oncologist which markers are relevant for your diagnosis specifically — a broad panel covering markers irrelevant to your cancer type is not more precise, just more expensive.
Does precision oncology mean I will get immunotherapy?
Not necessarily. Precision oncology means your treatment is matched to the biology of your tumour — and for many tumours, the matched treatment is chemotherapy, targeted therapy, surgery, or radiation rather than immunotherapy. Immunotherapy is one tool in the programme, indicated when biomarker results support its use. Being told it is not indicated for you is a precise answer based on your results, not a limitation of the programme.
How long does biomarker testing take before treatment can start?
Most standard biomarker tests — PD-L1, MSI, BRCA, individual gene tests — return results within one to two weeks. Comprehensive genomic profiling panels can take two to three weeks and may require sending the sample to a specialist laboratory. If treatment needs to begin urgently, your oncologist will discuss which tests are essential first. Do not assume that waiting for all results is always the right decision — the urgency of your situation is part of that judgement.
What happens if my tumour does not have any targetable markers?
This is common. Many cancers do not carry markers that point to a specific targeted therapy or indicate immunotherapy benefit. In that case, the precision in the programme lies in ruling those options out clearly rather than giving you a treatment unlikely to help. Your oncologist should then explain the recommended alternative and what it aims to achieve. A programme that tests and then recommends a different path is still doing its job.
Can I get a precision oncology second opinion without switching centres?
Yes. You can seek a second opinion on your molecular testing results and treatment plan without transferring your care. Bring your biopsy report, pathology results, any molecular or biomarker reports, and your imaging. A second-opinion consultation will review whether the testing was appropriate for your cancer type, whether the results were interpreted correctly, and whether the treatment recommendation follows from them. After that, you decide whether to continue at your current centre or move.
