Recommend A Treatment Plan
Use evidence to recommend a treatment plan in a biomedical case.
- Read a data table: Students need to find values, labels, and units before calculating or graphing.
- Fair-test logic: Variables and controls make comparisons meaningful.

Recommend the plan that matches the case facts. Stage II in one area can be removed by surgery; a negative marker rules out a targeted drug.
Use the case facts. The cancer is Stage II in one area (M0) and the marker test is NEGATIVE. Which plan best fits?
Approved| Case fact | What it tells you |
|---|---|
| Stage | Stage II: tumor is in one area, no distant spread (M0) |
| Marker test | Negative: the cancer does NOT carry the marker a targeted drug needs |
| Patient health | Healthy enough for surgery |
- A.Do nothing, because a Stage II cancer is still harmless
- B.Use every treatment at once so nothing is missed
- C.Give the targeted drug, since newer drugs work better than surgery on a Stage II cancer
- D.Surgery to remove the local tumor; the negative marker rules out the targeted drug

Answer: D. Surgery to remove the local tumor; the negative marker rules out the targeted drug
- Step 1: Use the stage: Stage II is in one area with no distant spread, so a local treatment like surgery can remove it.
- Step 2: Use the marker: The marker test is negative, so the targeted drug has nothing to lock onto and is ruled out.
Why it's right: Surgery fits a local Stage II tumor, and the negative marker correctly rules out the targeted drug.
- A: Stage II cancer is serious and needs treatment.
- B: Throwing every treatment at it adds harm without matching the facts.
- C: Being newest does not matter; the negative marker means the targeted drug won't work.

Fill these in as you work through the lesson.
- Treatment plan (the recommended set of treatments):
- Stage (how far the cancer has spread (I to IV)):
- Marker status (whether the cancer carries the marker a targeted drug needs):
- Overclaim (promising more than the evidence supports):
- Local vs. systemic (one-spot vs. whole-body treatment):
A good plan matches the treatment to the cancer's and status. If the marker test is , a targeted drug will not work. Promising a guaranteed cure is an .
- What two case facts most shape a treatment plan?
- Why can't you recommend a targeted drug when the marker test is negative?
- What makes a recommendation an overclaim?
A patient has Stage II cancer in one area (no spread) and a negative marker test. Recommend a plan using the facts, and explain why you would NOT promise a guaranteed cure.
