Background: The objective of this analysis was to present the clinical outcome of patients with microinvasive adenocarcinoma (AC)of the uterine cervix treated at the Department of Obstetrics and Gynecology between 1999 and 2010. Materials and Methods: The authors analysed 125 patients with microinvasive AC. The analysis involved the following parameters: women’s age at surgery, type of surgery, number of positive lymph nodes, and patient’s survival. Additionally, a questionnaire regarding history and symptoms before diagnosis and postoperative follow-up was developed and analysed specifically for this study. Results: The mean women’s age at surgery was 40.58 ± 9.58 years. In 70 women (56%), the performed treatment was conization, 34 women (27.2%) underwent simple hysterectomy, and 24 (19.2%) women had radical hysterectomy. In 14 (11.2%) women, the margins of the cone were not disease-free, in nine of them the authors later performed radical hysterectomy. From 14 women who became pregnant after treatment, 13 (16.9%) of them gave birth. One of the 125 patients diagnosed with microinvasive AC died and the cause of death was rectal carcinoma. Conclusion: The authors may conclude that conservative management of patients with microinvasive AC is safe when exact evaluation of tumor extension and surgical margins of the cone are considered, and results in very low risk of recurrence, lymph node disease, and death caused by cancer.
