Overview
Radiation therapy regimens
Shown below is a list of the different regimens radiation therapy for patients with non-small cell lung cancer. The list of regimens has been adapted from the 2014 NCCN Non-Small Cell Lung Cancer guidelines.[1]
Usual Dosages for Definitive Radiation Therapy
Administer fractions of 2 Gy over a period of 6 to 7.5 weeks to a total dose of 60 to 74 Gy.
Neoadjuvant Radiation Therapy Regimen
Administer fractions of 1.8 to 2 Gy over a period of 5 weeks to a total dose of 45 to 50 Gy.
Adjuvant Radiation Therapy Regimens
- Negative surgical piece margins: Administer fractions of 1.8 to 2 Gy over a period of 5 to 6 weeks to a total dose of 40 to 54 Gy.
- Positive surgical piece margins: Administer fractions of 1.8 to 2 Gy over a period of 6 weeks to a total dose of 54 to 60 Gy.
- Extracapsular nodal extension: Administer fractions of 1.8 to 2 Gy over a period of 6 weeks to a total dose of 60 to 70 Gy.
- Residual tumor: Administer fractions of 2 Gy over a period of 6 to 7 weeks to a total dose of 54 to 60 Gy.
Stereotactic Ablative Radiotherapy Usual Dosage
- Peripheral small tumors: 25 to 34 Gy not fractioned.
- Peripheral tumors and chest wall tumors larger than 1 cm: 45 to 60 Gy administered in 3 fractions.
- Central or peripheral tumors smaller than 5 cm: 48 to 60 Gy administered in 4 fractions.
- Central or peripheral tumors principally chest wall tumors smaller that 1 cm: 50 to 55 Gy administered in 5 fractions.
- Central tumors: 60 to 70 Gy administered in 8 to 10 fractions.
Palliative Radiation Therapy Regimens
Listed bellow are the recommended palliative radiation therapy regimens for patients with non-small cell lung cancer according to the 2014 NCCN Non-Small Cell Lung Cancer guidelines[1]
- Obstructive disease: Administer fractions of 3 Gy over a period of 2 to 3 weeks to a total dose of 30 to 45 Gy.
- Bone metastases associated with soft tissue mass: Administer fractions of 4 to 3 Gy over a period of 1 to 2 weeks to a total dose of 20 to 30 Gy.
- Bone metastases not associated with soft tissue mass: Administer fractions of 8 to 3 Gy over a period of 1 to 14 days to a total dose of 8 to 30 Gy.
- Patients with poor performance status and symptomatic chest disease: Administer fractions of 8.5 Gy over a period of 7 to 14 days to a total dose of 17 Gy.
- Metastatic disease in patients who have a poor performance status: Administer fractions of 8 to 4 Gy over a period of 1 to 7 days to a total dose of 8 to 20 Gy.
- Whole brain radiation therapy regimens for metastases to the brain are the following Adapted from the 2014 NCCN Central Nervous System Cancers guidelines[2]:
- 10 fractions of 3 Gy each to a total of 30 Gy.
- 15 fractions of 2.5 Gy each to a total of 37.5 Gy.
- 5 fractions of 4 Gy each to a total of 20 Gy. Good option for patients with poor performance status.
