Assessment Test

• 1. Soft Tissue Sarcomas:

  • Only occur in the extremities.
  • Are a complex group of diseases that need multiple modes of management.
  • Can be easily diagnosed by an Ultrasound Scan
  • Are best diagnosed with a Fine Needle Aspirate.

• 2. In the treatment of malignant primary bone tumours (bone sarcomas), Radiation Therapy has an important role in the primary treatment of:

  • Ewing Family Tumour
  • Osteosarcoma
  • Chondrosarcoma

• 3. Ewing Family Tumor is characterized by the following:

  • Simple translocation, large soft tissue mass and affects younger people.
  • Simple translocation, large soft tissue mass and affects older people.
  • Complex genetic changes, no soft tissue mass and affects older people.
  • Complex genetic changes, large soft tissue mass and affects younger people.

• 4. Osteochondromas:

  • Can be associated with a hereditary condition.
  • Continue growing throughout life, and as such need to be resected.
  • Do not undergo malignant change.
  • Are difficult to diagnose on a plain X-Ray.

• 5. An MRI scan can definitively diagnose a soft tissue sarcoma:

  • Yes
  • No

• 6. A 14 year old boy has a swollen tibia and pain for 6 months. You suspect a bone tumour. What would be the best first radiological investigation?

  • MRI scan.
  • Plain film X-ray.
  • A radionuclide bone scan.
  • An ultrasound scan.

• 7. Osteosarcoma:

  • Only occurs in childhood.
  • Cure rates as high as 75% can be achieved.
  • Is a benign tumour of bone.
  • Almost always results in an amputation.

• 8. A 35 year old man presents to his family doctor with a fast growing, 15 cm soft tissue mass in his right thigh. He has noticed it for three months. You examine him and think the lession is deep. What is the next best step?

  • Wait 3 weeks for an MRI before referring the patient.
  • Admit the patient to the hospital for investigations.
  • Perform a biopsy in the clinic.
  • Urgent referral to a multidisciplinary centre.

• 9. Giant Cell Tumor of Bone:

  • Is an aggressive cancer requiring major surgery
  • Typically occurs in the hands and feet.
  • Represents 20% of all benign bone tumour
  • Is a disease of childhood.

• 10. Referring to the causation of sarcomas

  • Most occur sporadically.
  • Most are associated with familial conditions.
  • Are mostly iatrogenic.
  • Can be related to trauma
