What is the primary role of radiation therapy in mesothelioma treatment?
Answer: Palliative symptom control and adjuvant therapy
Radiation therapy in mesothelioma is primarily used for palliative symptom control and as adjuvant therapy after surgery rather than as a curative monotherapy.
Hemithoracic radiation after EPP is intended primarily to:
Answer: Reduce local recurrence risk in the treated hemithorax
Hemithoracic radiation after EPP targets the entire treated side of the chest to reduce local recurrence in the surgical field.
Which radiation technique is considered most precise for mesothelioma, reducing dose to surrounding structures?
Answer: Intensity-Modulated Radiation Therapy (IMRT)
IMRT allows precise dose delivery with modulated beam intensity, sparing adjacent critical structures like the heart and contralateral lung.
Prophylactic irradiation of procedure tracts is used in mesothelioma to prevent:
Answer: Seeding of tumor cells along biopsy or drain tracks
Prophylactic irradiation of biopsy and drain tracts is used to prevent seeding of tumor cells along these procedure sites.
Which organ is the primary dose-limiting structure during pleural mesothelioma radiation therapy?
Answer: Contralateral lung
The contralateral lung is the primary dose-limiting structure because radiation pneumonitis in the remaining lung can be fatal.
Stereotactic Body Radiation Therapy (SBRT) is used in mesothelioma primarily for:
Answer: Treating discrete metastatic lesions
SBRT delivers high-dose, precisely targeted radiation to discrete metastatic lesions, offering palliative control with minimal surrounding tissue damage.
