Pelvic lymph node metastasis in microinvasive adenocarcinoma of cervix

Abstract

Microinvasion of cervical cancer was defined according to the International Federation of Gynecologists and Obstetricians classification as a depth of invasion of no greater than 3 mm and a horizontal dimension of no greater than 7 mm. Although the status of the lymph nodes is not included in the staging of cervical cancer, the presence or absence of lymph node metastasis provides important prognostic information and influences decision-making for treatment. For patient with stage IA1 microinvasive squamous cell carcinoma, the incidence of lymph node involvement is estimated to be 1%, but very little is known about lymph node metastasis in microinvasive adenocarcinoma of cervical cancer. We have experienced a case of pelvic lymph node metastasis in microinvasive adenocarcinoma of cervix with a depth of invasion of 3 mm or less, with no lymphovascular invasion. So, we report the case with brief review of literatures.
