Materials and methods. 26 patients (17 women, 9 men) aged 10 to 69 years (mean - 38,9 ± 14,9 years) with LGC were treated. All the patients underwent a complete clinical - instrumental examination, the diagnosis of LGC confirmed morphologically after surgery. Follow-up was from 13 to 204 months (median - 22.5 months) after surgery. Results. In 3 patients tumor stabilization was estimated, the others - various lo-cal/regional recurrences were identified. It had been shown that the basaloid subtype of ad-enocystic LGC prognostically was the most unfavorable. Distant metastases were found in 9 patients, 4 of them died (median follow up - 22.5 months). Conclusion. The efficiency of LGC treatment remains low with high risk of local and regional recurrence. Prognosis of LGC depends on several factors, including the histological type of the tumor, the presence of perineural invasion and, possibly, on the patient’s age.
