For gross disease that has achieved a complete radiographic response to hormone therapy (e.g. enlarged lymph nodes), the original area of the disease should be treated to an EQD2 of 42-56Gy

In general for stereotactic radiotherapy of metastases, a dose of 35 Gy in 5 fractions delivered in a conformal fashion and with dose homogeneity is an effective and safe dose for the majority of non-spine tumour targets. For spine metastases, a dose of 24 Gy in 2 fractions is highly recommended
