STEREOTACTIC REIRRADIATION IN TREATMENT OF RECURRENT HEAD AND NECK CANCER - OWN EXPERIENCE
Locoregional recurrence occurs in more than half of patients with squamous cell carcinoma of the head and neck (HNSCC) in two years from the time of primary treatment. At present day, there are no clear recommendations on the irradiation volumes, the total doses and the timing of reirradiation of these patients. Reirradiation with conventional methods had low efficacy and high radiation toxicity, which reduced the quality of life and, in some cases, these adverse effects were fatal. Based on the few publications on the choice of total doses and irradiation volumes, we evaluated the tolerability and effectiveness of repeated stereotactic irradiation using modern techniques IMRT and VMAT.
