Carcinoma in situ cervicis uteri: diagnosis, treatment and prognosis

A total of 252 patients with carcinoma in situ colli uteri were treated at the Women's Clinic at Turku University between 1964 and 1971. Seventy-seven percent of the patients came to the clinic for treatment after they had participated in a mass screening program (cytodiagnosis, colposcopy). Extrafascial hysterectomy was performed most often on women in the older age groups, while most of the younger patients were treated by conization. Patients were followed up for a minimum of 5 years. There was a 1.0% recurrence of invasive carcinoma and a 4.0% recurrence of noninvasive carcinoma. All invasive recurrences occurred after hysterectomy. None of the patients died from complications of carcinoma.
