Definition and treatment of microcarcinoma of the cervix uteri

Patients with tumors without vessel invasion have a better prognosis than patients with tumors of the same size with vessel invasion. The depth of stromal infiltration should be measured from the epithelial surface. In patients with an infiltration less than 1 mm, conization will be sufficient treatment, but hysterectomy is necessary when the disease is more advanced. When the tumor has infiltrated into vessels, additional treatment including pelvic lymphadenectomy or external irradiation should be performed.
