How to Present at Tumor Board (When the Room Already Knows the Medicine)

Tumor board is the most misjudged presentation in oncology and neuro-oncology. Presenters bring a Grand Rounds deck — background, pathophysiology, literature review — to a room of surgeons, radiation oncologists, medical oncologists, and pathologists who already know all of it.

The room does not need to be taught. It needs to make a decision: resect or radiate, adjuvant or observe, eligible for trial or not. The deck exists to get the room to that decision fast and with the right information in front of it.

Tumor Board Is Not Grand Rounds

The audience parameter changes the entire deck. For Grand Rounds you build for learners and you teach the reasoning. For tumor board you build for peers and you compress to the decision.

Set the audience honestly when you build. A deck pitched at residents wastes the room's time; a deck pitched at the board strips the teaching scaffolding you do not need and surfaces the data points the discussion will turn on.

The Structure That Drives a Decision

A tumor board case is short and fixed in order. Every slide earns its place by feeding the decision:

• One-line patient summary — age, performance status, the single sentence that frames everything.
• Imaging — the actual films, sized to be read across the room, not a thumbnail.
• Pathology / molecular — the markers that change management (IDH, MGMT, 1p19q, Ki-67), not the full report.
• The specific question — written as a question. "Resectable given proximity to motor cortex?" not "Discussion."
• Options on the table — the two or three real management paths, each with its evidence handle.
• Trial eligibility — named, with the one criterion that decides in or out.

Time Is the Hard Constraint

Tumor board gives a case three to five minutes before discussion. A 25-slide deck guarantees you get cut off before the question. Set the target duration when you build and let the deck be cut to fit it — deliberately, not by you skipping slides live while the chair watches.

The cut is the skill. A tumor board deck that respects the clock signals you understand the room. One that overruns signals you do not.

Speaker Notes Carry the Discussion

The slides are sparse on purpose. The depth lives in the notes: the effect size behind the option you favor, the trial inclusion line, the question the radiation oncologist always raises. When discussion starts you answer from notes without flipping slides — which is what separates a presenter who controls the room from one who is searching it.

The Point

Build for the room you are in. Tumor board is expert, fast, and decision-driven — set the audience and the duration to match, and let the deck compress to the question.

The best tumor board deck is the one nobody remembers, because the discussion started on time and landed on a plan.
