Assessment Test

• 1. 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.

• 2. 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.

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

  • Yes
  • No

• 4. A patient presents to his family doctor with a 4 cm mass that has been stable. How would you first try to determine if it was superficial?

  • If soft, it is probably on top of the fascia.
  • Have the patient tense the underlying muscle, if it becomes fixed it is superficial.
  • Have the patient tense the underlying muscle, if it becomes fixed it is deep.
  • Order an ultrasound scan.

• 5. A patient undergoes treatment including 5000cGy of external beam radiation and wide resection surgery for a large, deep high grade soft tissue sarcoma in the thigh. There is no evidence of metastases. How will you counsel the patient?

  • They will almost certainly succumb to the disease, so arrange for palliative care.
  • Most patients survive, but regular follow up is required.
  • The chance of further tumours is basically nil, so just get on with it.
  • There are no long term effects from the radiation treatment they received.

• 6. 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.

• 7. A patient has a superficial lesion that is 4 cm in size. It feels like a lipoma. Is it safe for the family doctor to remove this in her office?

  • Yes
  • No

• 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
