What does the “T” in the TNM staging system system represent?
- A The number of tumours removed
- B The size and/or extent of the primary tumour
- C The treatment given to the tumour
- D The tumour's histologic grade
Correct answer: The size and/or extent of the primary tumour
In the TNM system the “T” category describes the size and extent of the primary tumour (how far it has grown into nearby tissue).
What is meant by “N0” in cancer staging?
- A No information about the lymph nodes is available
- B There is no regional lymph node involvement
- C Multiple regional lymph nodes contain cancer
- D Regional lymph node status cannot be assessed
Correct answer: There is no regional lymph node involvement
“N0” indicates that regional lymph nodes are free of cancer spread (no involvement).
A cancer is classified as M1. What does this signify?
- A No distant metastasis
- B Microscopic metastasis only
- C Distant metastasis is present
- D Metastasis cannot be evaluated
Correct answer: Distant metastasis is present
“M1” in the TNM system means that distant metastasis (spread to other organs or distant nodes) is present.
What is the difference between cancer stage and grade?
- A Stage refers to cell appearance; grade refers to spread
- B Grade refers to tumour size; stage refers to histologic type
- C Stage describes how far cancer has spread; grade, how abnormal cells look
- D Stage and grade are interchangeable terms with the same meaning
Correct answer: Stage describes how far cancer has spread; grade, how abnormal cells look
Staging describes tumour size/extent/spread; grading describes how abnormal the cells are under the microscope (their differentiation).
A tumour is described as “well-differentiated” under the microscope. What grade would that likely correspond to?
- A High grade, around grade 3 to 4
- B Low grade, around grade 1
- C Grade cannot be inferred from differentiation
- D Intermediate grade, around grade 2
Correct answer: Low grade, around grade 1
Well-differentiated tumours resemble normal tissue and are considered low grade (e.g., grade 1) with a more favorable prognosis.
Which statement correctly describes Stage IV cancer?
- A Local tumour only, with no nodal or distant spread
- B Carcinoma in situ only
- C Cancer has spread to distant sites (metastasis)
- D Disease confined to regional lymph nodes only
Correct answer: Cancer has spread to distant sites (metastasis)
Stage IV generally indicates metastatic disease (spread to distant organs).
The term “pT2” often seen in pathology reports refers to what?
- A Pathologic primary-tumour size category 2, assessed after surgery
- B Partial tumour removal of category 2 extent
- C Clinical primary-tumour category 2, assessed before treatment
- D Pediatric primary-tumour category 2 staging
Correct answer: Pathologic primary-tumour size category 2, assessed after surgery
The prefix “p” denotes pathologic staging (after surgery/biopsy) and “T2” describes tumour size/extent category 2.
What does a “Grade 3” tumour indicate?
- A Cells appear nearly normal and grow slowly
- B Cells appear mildly abnormal and grow at a moderate pace
- C Cells appear very abnormal and behave aggressively
- D Cell appearance does not reliably predict tumour behaviour
Correct answer: Cells appear very abnormal and behave aggressively
Grade 3 tumours are poorly differentiated or undifferentiated, look very abnormal and tend to grow/spread more aggressively.
In which scenario would the TNM system not be typically used?
- A a. Breast carcinoma
- B b. Colon adenocarcinoma
- C c. Acute leukaemia
- D d. Non-small cell lung carcinoma
Correct answer: c. Acute leukaemia
The TNM system is mainly used for solid tumours; hematologic malignancies like acute leukaemia use different classification systems.
What does “Tis” in the TNM classification mean?
- A Tumour size cannot be assessed at presentation
- B Tumour confined to the epithelium of origin
- C Tumour that has spread to distant metastatic sites
- D Tumour arising in skeletal or bone tissue
Correct answer: Tumour confined to the epithelium of origin
Tis denotes carcinoma in situ: malignant cells that remain within the epithelium of origin and have not breached the basement membrane, so there is no capacity for metastasis. TX means the primary tumour cannot be assessed and T0 means no evidence of a primary tumour, while distant spread is recorded in the M category.
A cancer is staged as T3N0M0. What can be inferred?
- A a. Large primary tumour, no nodal or distant spread
- B b. Small tumour, nodal involvement present, no distant spread
- C c. No tumour visible, no spread
- D d. Distant metastasis present only
Correct answer: a. Large primary tumour, no nodal or distant spread
T3 denotes larger tumour size/extension; N0 means no regional lymph node involvement; M0 means no distant metastasis.
Why is accurate cancer staging important for patient care?
- A It has no real impact on how treatment is planned
- B It guides treatment, prognosis and research comparisons
- C It is relevant only for billing and insurance records
- D It removes any need for separate histologic grading
Correct answer: It guides treatment, prognosis and research comparisons
Accurate staging guides treatment decisions (surgery, chemo, radiation), helps estimate prognosis, and allows comparison across patients and studies.
Which phrase best describes “clinical stage” compared to “pathologic stage”?
- A Clinical stage follows surgery; pathologic stage precedes treatment
- B Clinical stage is estimated pre-treatment; pathologic stage uses surgical findings
- C Both terms describe exactly the same staging assessment
- D Pathologic stage relies solely on imaging study results
Correct answer: Clinical stage is estimated pre-treatment; pathologic stage uses surgical findings
Clinical stage (c-) uses physical exam/imaging before treatment; pathologic stage (p-) uses surgical/histologic findings.
For prostate cancer, the Gleason score is used in addition to TNM staging. What aspect does the Gleason score assess?
- A The overall size of the prostate gland at diagnosis
- B The patient's age and general health at diagnosis
- C Histologic grade of the tumour cells (how abnormal they appear)
- D The extent of metastatic spread to distant organs
Correct answer: Histologic grade of the tumour cells (how abnormal they appear)
The Gleason score is a grading system for prostate cancer that describes how much the tumour cells differ from normal prostate cells, assessing aggressiveness.
A patient’s tumour is designated G4. What implication does this have for prognosis?
- A Likely excellent prognosis with minimal expected spread
- B Low grade tumour with slow, indolent growth expected
- C High grade tumour; more aggressive with poorer prognosis
- D Grade has essentially no effect on the patient's prognosis
Correct answer: High grade tumour; more aggressive with poorer prognosis
Grade 4 indicates poorly differentiated or undifferentiated cells, signifying more aggressive behaviour and generally a worse prognosis.
Which statement is true regarding Stage I cancer?
- A Usually involves distant metastatic spread to organs
- B Very early cancer, small and confined to the organ of origin
- C Stage I disease always requires palliative-only management
- D Stage I disease always involves regional nodal involvement
Correct answer: Very early cancer, small and confined to the organ of origin
Stage I often means the tumour is small, confined to the organ, and has not yet spread to lymph nodes or distant sites.
Which of the following impacts grading more than staging?
- A The maximum size of the primary tumour
- B The degree of regional lymph node involvement
- C Histologic appearance and differentiation of tumour cells
- D The presence or absence of distant metastasis
Correct answer: Histologic appearance and differentiation of tumour cells
Grading is based on how abnormal the tumour cells look under microscope (their differentiation); staging is based on extent/spread.
Why might two patients with the same stage of cancer have different prognoses?
- A Stage already captures all relevant prognostic factors
- B Tumour grade, molecular markers, health and treatment differ
- C Stage on its own determines the outcome exactly
- D One patient may have misreported their presenting symptoms
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.
In breast cancer, a tumour reported as pT1aN0M0 would mean what?
- A Very small primary tumour, no nodal or distant spread, pathologically confirmed
- B Large primary tumour with many regional nodes involved
- C Distant metastasis present in one or more distant organs
- D No primary tumour could be detected on assessment
Correct answer: Very small primary tumour, no nodal or distant spread, pathologically confirmed
pT1a indicates very small tumour (≤1 cm), N0 means no regional lymph nodes, M0 means no distant metastasis — good prognostic sign.
A nurse explains to a patient that “your cancer is T2N1M0, grade 2”. Which statement best reflects what they should understand?
- A A large tumour with distant metastasis and high-grade cells
- B A moderate tumour, some nodal spread, no distant spread, moderately differentiated
- C A very small tumour, no nodes or spread, but highly abnormal cells
- D The tumour's grade and stage essentially mean the same thing
Correct answer: A moderate tumour, some nodal spread, no distant spread, moderately differentiated
T2 = moderate tumour size/extent; N1 = some nodal spread; M0 = no distant spread; grade 2 = moderately differentiated tumour which is intermediate.
