[Concentrated irradiation of bone metastasis (author's transl)]

One hundred patients with bone metastasis of various histological types have been submitted to a concentrated irradiation: 2 sessions of 850 rads or 650 rads over 3 days. Pain disappeared in 65% of the cases in a 3 to 7 days delay, for a mean duration of two months. The mean survival of this groups of patients is 4.3 months. The concentrated irradiation is well tolerated. Authors emphasize the value of this kind of treatment for patients with plurifocal metastasis and short survival.
