  • 2. 

    A benign epithelial neoplasm that forms glandular patterns, or, is derived from glandular tissue but does not necessarily produce glandular patterns.

    • Chondroma

    • Osteoma

    • Fibroma

    • Adenoma

    • Papilloma

    • Hamartoma

    Correct Answer
    A. Adenoma
    Explanation
    Adenoma is a benign epithelial neoplasm that can form glandular patterns or be derived from glandular tissue, but it does not necessarily produce glandular patterns. This means that while an adenoma may have glandular characteristics, it can also have other patterns or structures. The other options listed, such as chondroma, osteoma, fibroma, papilloma, and hamartoma, do not fit the description of a neoplasm derived from glandular tissue.

  • 3. 

    Seminomas are extremely radiosensitive and can usually be eradicated by radiotherapy.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Seminomas are a type of testicular cancer that are known to be highly sensitive to radiation therapy. This means that radiotherapy is an effective treatment option for seminomas and can often completely eliminate the cancer cells. Therefore, the statement that seminomas can usually be eradicated by radiotherapy is true.

    Rate this question:

  • 4. 

    Malignant tumour arising in mesnchymal tissue

    • Sarcoma

    • Osteoma

    • Carcinoma

    • Adenoma

    • Papilloma

    • Hamartoma

    Correct Answer
    A. Sarcoma
    Explanation
    Eg. fibrosarcoma, liposarcoma, leiomyosarcoma, rhabdomyosarcoma, chondrosarcoma, osteogenic sarcoma.

    Rate this question:

  • 5. 

    Benign tumour made up of parynchymal cells representative of more than one germ layer (usually all 3).

    • Sarcoma

    • Osteoma

    • Carcinoma

    • Teratoma

    • Papilloma

    • Hamartoma

    Correct Answer
    A. Teratoma
    Explanation
    Ovarian cystic teratoma is also called a dermoid cyst. They arise from totipotent cells.

    Rate this question:

  • 6. 

    Malignant tumour of epithelial origin from any of the 3 germ layers.

    • Sarcoma

    • Osteoma

    • Carcinoma

    • Adenoma

    • Papilloma

    • Hamartoma

    Correct Answer
    A. Carcinoma
    Explanation
    It is also common tho identify the cell pattern and organ of origin eg, renal cell adenocarcinoma, bronchogenic squamous cell carcinoma.

    Rate this question:

  • 7. 

    Embryonal carcinomas of the testis are extremely radiosensitive and can usually be eradicated by radiotherapy.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Embryonal carcinomas of the testis are not radiosensitive.

    Rate this question:

  • 8. 

    Tumours with low growth fractions are generally more susceptible to chemotherapy.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Tumours with HIGH growth fractions are generally more susceptible to chemotherapy because most anti-cancer agents act on cells in the cell cycle. After debulking surgery, remaining cells may enter the cell cycle producing a higher growth fraction and making subsequent chemotherpy more effective.

    Rate this question:

  • 9. 

    What % of people with solid organ tumours have metastases present at diagnosis?

    • 5%

    • 10%

    • 20%

    • 30%

    • 40%

    • 50%

    Correct Answer
    A. 30%
    Explanation
    30% of people with solid organ tumors have metastases present at the time of diagnosis. This means that nearly one-third of individuals with solid organ tumors already have the cancer spread to other parts of their body when it is first detected. This high percentage highlights the aggressive nature of these tumors and the importance of early detection and treatment to improve outcomes.

    Rate this question:

  • 10. 

    Which of the following is a benign neoplasm?

    • Wilm's tumour

    • Melanoma

    • Hepatoma

    • Seminoma

    • Mesothelioma

    • Hamartoma

    Correct Answer
    A. Hamartoma
    Explanation
    All the others are malignant, despite ending with -oma instead of carcinoma or sarcoma. They are now entrenched in our medical vocabulary.

    Rate this question:

  • 11. 

    To retain their self-renewing capacity, leukaemic Tumour initiating cells require the expression of which gene?

    • P161NK4a

    • P14ARF

    • BMI1

    • SHOX

    • FMRI

    • COL5A1

    Correct Answer
    A. BMI1
    Explanation
    Leukaemic Tumour initiating cells require the expression of the BMI1 gene in order to retain their self-renewing capacity. This gene plays a crucial role in regulating stem cell self-renewal and differentiation. Without the expression of BMI1, these cells would lose their ability to continuously divide and regenerate, which is essential for the progression and maintenance of leukemia.

    Rate this question:

  • 12. 

    The proportion of cells within the tumour population that are in the proliferative pool is called the _ _ _ _ _ _     _ _ _ _ _ _ _ _.

    Correct Answer
    growth fraction
    Explanation
    Usually, by the time a tumour is clinically detectable, most cells have left the replicating pool. The higher the growth fraction, the more cell production will exceed cell loss and the faster the tumour will grow.

    Rate this question:

  • 13. 

    Which of the following malignant neoplasms do not metastasise? (2)

    • Melanomas

    • Osteosarcomas

    • Squamous cell carcinomas of the skin

    • Basal cell Carcinomas of the skin

    • Most malignant neoplasms of glial cells

    • Renal cell carcinomas

    Correct Answer(s)
    A. Basal cell Carcinomas of the skin
    A. Most malignant neoplasms of glial cells
    Explanation
    Both are locally invasive though.
