Deck 28: Bone,Cartilage and Soft Tissue Sarcomas

Question 1

In which anatomical location are STSs most common?

A) head and neck
B) upper extremity
C) lower extremity
D) trunk

Answer 1

B
Roughly 60% of STSs are found in extremities,with the thigh being most common.

Question 2

Which of the following is an acceptable radiation therapy treatment technique for STS?
I)external beam
II)brachytherapy
III)intraoperative

A) I and II
B) I and III
C) II and III
D) I,II,and III

Answer 2

D
STSs are adequately treated using external beam radiotherapy,brachytherapy,and IORT.

Question 3

It is important when treating an extremity for STS to have a strip of unirradiated tissue near the treatment volume to: I.maintain some lymphatic function
II)avoid increased fracture possibilities
III)avoid circumferential fibrosis

A) I and II
B) I and III
C) II and III
D) I,II,and III

Answer 3

B
Total circumferential radiation of extremities is not recommended because the likelihood of lymphedema and fibrosis is increased.Fracture potential is neither increased nor decreased by leaving a strip of unirradiated tissue.

Question 4

When used with radiation therapy,which of the following reduces the loss of function and improves overall control?

C) lower extremity
D) trunk

Question 6

Preoperative radiation therapy for STS is performed to: I.kill the reactive rim of tumor cells before they are cut into
II)decrease the risk of implantation
III)attempt to preserve as much normal function as possible

A) I and II
B) I and III
C) II and III
D) I,II,and III

A) red
B) white
C) blue
D) yellow

Question 9

Most STSs generally spread through: I.the lymphatic system
II)direct invasion and extension
III)hematogenous spread

A) I and II

Where should the upper and lower field edges be placed for the treatment of metastatic spine cancer?

A) mid-vertebral body
B) medial aspect of the vertebral body
C) superior aspect of the vertebral body
D) intervertebral space

Question 18

Overall,STS requires which dose of radiation to achieve local control and long-term survival?

A) low
B) medium
C) high

Question 19

What is the most common site of metastasis from a primary bone cancer?

A) brain
B) bowel
C) lung
D) bone

Question 20

What is the most important prognostic factor for osteosarcoma?
