[Evolution of some epidemiologic factors in invasive carcinoma of the uterine cervix. The period from 1972-1985]. / Evolución de algunos factores epidemiológicos en el carcinoma invasor de cuello uterino. Período 1972-1985.

204 cases of invasive carcinoma of the uterine cervix seen in the period 1972-1985 are studied. The incidence was higher from 50 to 69 years of age and maximum during the last years of the decade of the fifties. It was verified that the early beginning of sexual intercourse increases the number of cases and the age of presentation, and also that invasive uterine cervix cancer is more common in women with 3 or more pregnancies, while the incidence decreases in women with 1 or 2 pregnancies and specially in nulliparous virgins.

CIN I and CIN II can be treated by colposcopy-guided biopsy. Control examinations must be made every six months. Persistence of a CIN II lesion is an indication for conization. Some CIN III cases can be treated by conization, but considering the frequency of residual lesions and insufficient conization, a total hysterectomy is a safer procedure.
