What Happens During a Multidisciplinary Tumor Board?

A tumor board is a scheduled meeting where doctors from several specialties review individual patients' cases together and agree on a treatment recommendation. The National Cancer Institute describes it as a treatment planning approach in which experts from different disciplines review and discuss a patient's medical condition and treatment options — typically a medical oncologist, a surgical oncologist and a radiation oncologist among others.

It is one of the few structural features of cancer care that meaningfully changes how decisions get made, and most patients never hear about it.

The core group:

• Medical oncologist — chemotherapy, immunotherapy, targeted and hormone therapy.
• Surgical oncologist — whether and how the tumor can be removed.
• Radiation oncologist — whether radiation has a role and in what sequence.
• Pathologist — projects your slides and walks through what the tissue shows.
• Radiologist — pulls up your scans and re-reads them live, comparing with priors.

Depending on the program you may also find an oncology nurse navigator, an advanced practice provider, an oncology pharmacist, a genetic counselor, a clinical trial coordinator, a palliative care physician, a social worker, and residents or fellows.

Larger centers run disease-specific boards — breast, thoracic, gastrointestinal, genitourinary, neuro, sarcoma — and often a separate molecular tumor board that reviews genomic test results and matches mutations to targeted drugs or trials.

Cases are submitted in advance by the treating physician. A typical meeting covers eight to fifteen cases in an hour, so each gets a few minutes.

The presenting doctor gives a short history: age, relevant medical problems, how the cancer was found, what has been done so far. The radiologist displays the imaging and states the findings and stage. The pathologist projects the slides and confirms the diagnosis, grade and biomarkers. Then the specialists discuss: is this resectable, should systemic therapy come first, is radiation indicated, is there a trial, is further testing needed before deciding.

The group arrives at a recommendation. A coordinator records it, and it should end up in your chart.

Two things happen in that room that do not happen in a clinic visit. Slides and images are re-examined by fresh eyes, which is why staging and occasionally the diagnosis itself change. And specialists who would otherwise never meet about your case have to reconcile their views in front of each other.

Patients do not attend. It is not a hearing and there is no vote you take part in.

The recommendation is advisory, not binding. Your treating physician remains responsible for your care and makes the final decision with you. They may depart from the board's view for reasons specific to you — other illnesses, your own goals, information the group did not have.

Not every case is presented. Programs prioritize new diagnoses, complex or unusual cases, disagreements between specialists, recurrences, and cases where a trial might apply. A textbook case following a clear guideline may never be discussed, and that is not neglect.

Ask the question plainly at your next appointment: "Has my case been presented at tumor board? If not, can it be?"

If it has, ask what was recommended, whether there was disagreement, and whether it can be documented in your chart so you can read it. If it has not and your case is complex — an unclear diagnosis, specialists giving you different plans, a rare cancer, a recurrence — ask for it to be scheduled. This is a normal request.

If your practice does not hold tumor boards, ask whether it participates in a regional or virtual one, or can refer your case for external review. Commission on Cancer accredited programs are required to hold regular multidisciplinary cancer conferences, which is one practical reason accreditation is worth checking when choosing where to be treated.

Ask why. There is often a good answer — a comorbidity, a preference of yours, something learned since the meeting. What you want is the reasoning, not compliance for its own sake. And if you cannot get an explanation you can follow, that is worth noting in its own right.
