[Reirradiation of brain metastasis: Review of the last five years].

No recommandations have been established for reirradiation of brain metastases yet. The purpose of this review is to analyse the data of the five last years about the feasibility, efficacy and tolerance of reirradiation of brain metastases. Reirradiation can be 3D conformal or stereotactic. Whole brain irradiation seems appropriate for multiple brain metastases in order to obtain symptomatic relief, with or without supportive care. Stereotactic reirradiation has shown satisfying results in terms of overall survival, local control, without significant toxicity. Prospective trials are necessary in order to validate consensual recommandations.
