M Part I

Question 1

complete physical examination of the pt and pt tumour

Answer 1

Clinical Evaluation

Question 2

oncologist must be aware of the biological and pathologic characteristics of the tumor as well as all clinical manifestations so that proper microextensions of the tumor can be included in traetment volume

Answer 2

Diagnostic Work-up

Question 3

measures the degree of malignancy spread

Answer 3

Staging

Question 4

treatment goal is obtain complete durable remission; expected probability of surviving even if chance is low

Answer 4

Curative Treatment

Question 5

treatment considered curative, consists of irradiation of microscopically uninvolved areas

Answer 5

Prophylactic Treatment

Question 6

limited intent of improving pt’s quality of life and prolonging survival

Answer 6

Palliative Treatment

Question 7

Beam delivery systems:

Answer 7

1. conventional
2. Conformal
3. IMRT/IGRT

Question 8

-simple treatment delivers uniform dose of 2-4 beam angles
-beam shape: rectangular or square
-beam hits healthy tissue as well
-doses have to be kept low

Answer 8

Conventional Radiotherapy - 1960s

Question 9

custom-molded blocks match beam shape to tumor profile
typical treatment use 4-6 beam angles
dose relatively low
slow and labor intensive

Answer 9

3S conformal Rad Thera

Question 10

conform the treated volume to the planning target volume; MLC is an option for this

Answer 10

conformal rad thera

Question 11

inverse treatment planning
divides each treatment in multiple segments (up to 500/angle)
allows dose escalation for aggressive tumor

Answer 11

IMRT

Question 12

desired dose distribution to PTV and critical organs prescribed accdg to dose volume constraints with penalty systems for directions

Answer 12

Inverse Treatment Planning for IMRT
