[Radiation therapy in bone metastases from lung cancer].

The record of 73 patients with 153 sites of bone metastases from a lung cancer treated by radiation have been reviewed to evaluate the effectiveness of pain relief. Radiation therapy for bone metastases was found to be very effective. Sufficient symptomatic improvement was achieved in 94% of all patients, while 63% obtained almost complete pain relief that was sustained until death. Onset of a symptomatic response to radiotherapy was within less than 20 Gy in total dose in more than 80% of all patients. There were no significant differences in the frequency of pain relief among the various histological types of primary lung tumors.
