FLAMARIQUE, S et al. Re-irradiation with SBRT (Stereotactic Body Radiation Therapy) for locoregional unresectable relapse of head and neck cancer: a case report. Anales Sis San Navarra [online]. 2019, vol.42, n.3, pp.339-343.  Epub 20-Abr-2020. ISSN 1137-6627.  https://dx.doi.org/10.23938/assn.0715.

Patients with an unresectable recurrence of head and neck carcinoma (HNC) have a poor prognosis, with limited treatment options. Recent technical advances allow radiotherapy (RT) to be handled with great precision, making it possible to re-irradiate recurrent tumors by means of stereotactic body radiotherapy (SBRT) with high doses of RT while protecting healthy tissues near the tumor. Although this technique has been used to irradiate different primary tumors and their metastases, SBRT in HNC has had a much slower evolution than in the mentioned locations. This is due to the difficulties in re-irradiating the HNC, because of the expected toxicity as it is a relatively small area with dense vascularization and innervation, and where several senses are located.

We present the first case of a HNC re-irradiated with SBRT in the Complejo Hospitalario de Navarra; the patient showed a complete response and continues to be disease-free sixteen months after the irradiation.
