[Non-small cell lung cancer irradiation in elderly]

People over the age of 65 are often excluded from participation in oncological clinical trials. However, more than half of patients diagnosed with non-small-cell lung cancer are older than 65 years. Any therapeutic strategy must be discussed in multidisciplinary meetings after adapted geriatric assessment. Patients who benefit from the comprehensive geriatric assessment (CGA) of Balducci and Extermann are those whose G8 screening tool score is less than or equal to 14. Age itself does not contraindicate a curative therapeutic approach. Stereotactic radiotherapy is an alternative to surgery for early stages in elderly patients who are medically inoperable or who refuse surgery, because it significantly increases overall survival. Mostly sequential (rarely concomitant) chemoradiotherapy can be proposed to elderly patients with locally advanced stages in good general state of health. For the others, an exclusive palliative radiotherapy, a single or dual agent of chemotherapy, a targeted drug or best supportive care only may be discussed.
