Palliative chest irradiation in sitting position in patients with bulky advanced lung cancer.

Some patients with bulky advanced lung cancer are not able to lie down because of dyspnea. We therefore designed a technique for irradiation in a sitting position by using a dedicated chair. The reproducibility of the sitting position was high and all ten patients preferred this position over lying down. In selected patients who are unable to lie down, palliative irradiation in a sitting position may be an option.
