Squamous carcinoma was observed in 92,3% cases of CC, adenocarcinoma - in 7,7% cases among women to 50years old and ones in 9,8% cases among women older than 50 years.

Distribution according to FIGO clinical stages of patients with CC older 50 years was: I stage - 17,6% cases, II - 19,6%, III - 44,9% and IV - 17,9%. Advanced CC increased from patients older 50 years. 73,6%o patients with CC at the age before 50 years were treated by surgery, 30,2% - by surgery and X-ray therapy and 24,5% - only by X-ray therapy. 21,2% patients with CC older 50 years were treated by surgery and X-ray therapy and 63,6% of ones were treated by X-ray therapy only.
