A

66-70 Gy for high risk and 44-50 Gy for low risk and 54-63 for intermediate-risk

17
Q

What is the XRT dose for post-op treatment? (high, Intermediate and low risk)

A

66-60 Gy for high risk (+ margins) and same for low and intermediate risk

18
Q

The radiation technique for salivary glands is designed for what?

A

to fit local invasion and lymphatic spread, wedged pair, and bolus over spread

19
Q

In terms of patient orientation, what can be done in terms of treating for salivary gland?

A

Patient can be positioned on side with lateral side of the head facing upwards

20
Q

What is the treatment technique orientation utilized for cancers of the salivary gland?

A

Wedged pair, superior and inferior oblique fields

21
Q

What is the significance of the oblique fields for salivary gland rt tx?

A

the obliques direct the beam away from the oral cavity and orbits, requires a table rotation of 90

22
Q

When using anterior and posterior obliques for Salivary gland treatment, what should be considered?
