    Author: Urban A, Miszczyk L, Maciejewski B.
    Journal: Otolaryngol Pol; 2005; 59(1):21-5. PubMed ID: 15915914.
    Abstract:
    PURPOSE: The purpose of this investigation was to evaluate the quality of life, measured in LENT-SOMA and DISCHE scale, of patients with xerostomia as late irradiation injury. MATERIALS AND METHODS: 45 head and neck cancer patients were radically irradiated receiving doses from 48 Gy to 76.8 Gy (mean: 65.1 Gy) on PTV. Patients received doses from 48 to 76 Gy on salivary gland (mean: 63.8 Gy, SD: 8). The irradiation injury of the oral cavity was assessed using DISCHE scale at the end of radiotherapy and late radiation sequels of salivary gland was assessed in 6 and 7 month after radiotherapy using DISCHE and LENT-SOMA scale. The average follow-up for this group of patients was 8 months. RESULTS: All patients with 6 and more points of acute reactions assessed in DISCHE scale at the end of radiotherapy have had xerostomia in follow-up period. Results measured by LENT-SOMA scale was similar to DISCHE scale. CONCLUSIONS: Dose escalation of radiotherapy increases number of xerostomia as late irradiation injury. Both scales (LENT-SOMA and DISCHE) are similar in qualifying and quantifying of salivary gland radiation injury. Minimal therapeutic dosage prescribed on salivary gland after which irradiation injury occurred was 63 Gy.
