Mesothelioma Therapy Radiation Therapy 1

Question 1

What is the primary role of radiation therapy in mesothelioma treatment?

Accepted Answer

Palliative symptom control and adjuvant therapy

Answer

Radiation therapy in mesothelioma is primarily used for palliative symptom control and as adjuvant therapy after surgery rather than as a curative monotherapy.

Question 2

Hemithoracic radiation after EPP is intended primarily to:

Accepted Answer

Reduce local recurrence risk in the treated hemithorax

Answer

Hemithoracic radiation after EPP targets the entire treated side of the chest to reduce local recurrence in the surgical field.

Question 3

Which radiation technique is considered most precise for mesothelioma, reducing dose to surrounding structures?

Accepted Answer

Intensity-Modulated Radiation Therapy (IMRT)

Answer

IMRT allows precise dose delivery with modulated beam intensity, sparing adjacent critical structures like the heart and contralateral lung.

Question 4

Prophylactic irradiation of procedure tracts is used in mesothelioma to prevent:

Accepted Answer

Seeding of tumor cells along biopsy or drain tracks

Answer

Prophylactic irradiation of biopsy and drain tracts is used to prevent seeding of tumor cells along these procedure sites.

Question 5

Which organ is the primary dose-limiting structure during pleural mesothelioma radiation therapy?

Accepted Answer

Contralateral lung

Answer

The contralateral lung is the primary dose-limiting structure because radiation pneumonitis in the remaining lung can be fatal.
