Cancer staging and grading · NCLEX Exam

Why might two patients with the same stage of cancer have different prognoses?

  1. Stage already captures all relevant prognostic factors
  2. Tumour grade, molecular markers, health and treatment differ
  3. Stage on its own determines the outcome exactly
  4. One patient may have misreported their presenting symptoms
Show answer and explanation

Correct answer: Tumour grade, molecular markers, health and treatment differ

Prognosis depends not just on stage, but also on tumour grade, molecular features, patient comorbidities and treatment responses, so same stage might yield different outcomes.
