(A-C) T8 metastasis evolution after iterative irradiation. (A) 2006: First presentation: large deposit in the D8 vertebra with wedge compression (Bilsky grade 1a with epidural impingement). (B) 2014: First recurrence: osseous lysis lesion of the anterior portion of the T8 vertebra body (C). 2021: Further recurrence: right transverse pedicle of D8 vertebra (D). 2022: Recent follow-up (April 2022) showing complete response.

A dose of 30 Gy in 5 fractions at isodose 80% (maximum dose in the PTV: 37.5 Gy.) was planned for the second course of SBRT (third course of irradiation) using a CyberKnife system ( Figure 2C ).
