Radiation treatment decreases bone cancer pain, osteolysis and tumor size.

Radiotherapy is the cornerstone of palliative treatment for primary bone cancer in animals and metastatic bone cancer in humans. However, the mechanism(s) responsible for pain relief after irradiation is unknown. To identify the mechanism through which radiation treatment decreases bone cancer pain, the effect of radiation on mice with painful bone cancer was studied. Analysis of the effects of a 20-Gy treatment on localized sites of painful bone cancers was performed through assessments of animal behavior, radiographs and histological analysis. The findings indicated that radiation treatment reduced bone pain and supported reduced cancer burden and reduced osteolysis as mechanisms through which radiation reduces bone cancer pain.

Back pain and sciatica: controlled trials of manipulation, traction, sclerosant and epidural injections.

Four treatment regimens for patients with specified combinations of low back pain and sciatica were evaluated. The largest group studied had low back pain with limited straight-leg raising (SLR) and in them the beneficial effect of manipulation in hastening pain relief was highly significant. In similar patients without limitation of SLR, the effect was of borderline significance. In all the other groups, treated patients also recovered more quickly than their controls. Traction, for patients with low back pain and sciatica, and epidural injections when a root palsy was present also produced some significant pain relief. The effect of sclerosants for back pain was less clear.
